Case Style:

State Compensation Insurance Fund v. Readylink Healthcare, Inc.

Case Number: D075942

Judge: Aaron, J.

Court: California Court of Appeals Fourth Appellate District, Division One on appeal from the Superior Court, County of Riverside

Plaintiff's Attorney: Edward D. Pomerance, Vincent S. Gannuscio and David R. Ginsburg

Defendant's Attorney: Anthony Lewis, Noah Graff, R. Timothy O'Connor, Eric P. Jones, Tony M. Chang and Seaton Tsai

Description: Defendant ReadyLink Healthcare, Inc. (ReadyLink) is a nurse staffing company
that places nurses in hospitals, typically on a short-term basis. Plaintiff State
Compensation Insurance Fund (SCIF) is a public enterprise fund created by statute as a
workers' compensation insurer. Like private workers' compensation insurers, SCIF
provides workers' compensation insurance to employers. The premiums that SCIF
charges are based in part on the employer's payroll for a particular insurance year.
SCIF and ReadyLink have been engaged in a multiyear, multijurisdictional dispute
over the final amount of workers' compensation insurance premium that ReadyLink owes
to SCIF for the 2005 policy year, from September 1, 2005 to September 1, 2006, based
on an audit of ReadyLink's payroll for that year performed by SCIF. During the audit,
SCIF determined that certain payments made by ReadyLink to its nurses, which
ReadyLink characterized as per diem payments, should instead be considered to be
payroll under the relevant workers' compensation regulations.1 SCIF's audit resulted in a
significant increase in ReadyLink's premium for the policy year at issue.

ReadyLink challenged SCIF's application of the regulations by filing an appeal of
the audit to the Insurance Commissioner. The Insurance Commissioner approved SCIF's
application of the relevant regulation. A trial court rejected ReadyLink's petition for a

1 Under the relevant regulations, per diem payments refer to "reimbursement for
additional living expense by virtue of job location." (Italics added.)
3
writ of administrative mandamus to prohibit the Insurance Commissioner from enforcing
its decision, and an appellate court affirmed the trial court's judgment.2
SCIF subsequently filed the action underlying this appeal, pleading causes of
action including breach of contract, and seeking a judgment for damages against
ReadyLink for its failure to pay the additional premium amount that SCIF had calculated
was owed pursuant to its audit of ReadyLink's 2005 policy year payroll. ReadyLink
answered SCIF's complaint and asserted a number of affirmative defenses, including
estoppel, waiver, and fraud. ReadyLink was later granted leave to file an amended
answer, in which it provided additional factual allegations supporting its affirmative
defenses.
SCIF moved for judgment on the pleadings, claiming that the issue of the premium
that ReadyLink owed for the 2005 policy year had been previously determined in the
administrative proceeding and had been affirmed by subsequent judicial review of the
administrative decision, and further claiming that issues related to ReadyLink's
affirmative defenses had also been litigated in the prior proceedings. The trial court
agreed with SCIF and concluded that SCIF's "action was necessary to reduce SCIF's

2 ReadyLink also filed a separate putative class action in federal court, seeking a
declaratory judgment that federal tax law preempted the Insurance Commissioner's
decision regarding what an employer must demonstrate in order for per diem payments to
be excluded from payroll calculations for purposes of workers compensation.
ReadyLink's federal lawsuit was ultimately dismissed, and the dismissal was upheld on
appeal on the ground of issue preclusion, in view of an intervening California Court of
Appeal opinion rejecting the federal preemption argument.

claim to the premium owed to a judgment," and that "[t]he amount owed is precisely
what was determined in the underlying administrative decision and appeals." The trial
court granted SCIF's motion for judgment on the pleadings and entered a judgment in
favor of SCIF in the amount of $555,327.53, plus prejudgment interest of $571,606.99.
On appeal, ReadyLink contends that the trial court erred in granting SCIF's motion
for judgment on the pleadings, and also asserts that the trial court erred in denying
ReadyLink's motions to compel further discovery responses from SCIF. According to
ReadyLink, the trial court erred in concluding that the amount of premium it owes SCIF
for the 2005 policy year was determined in prior proceedings. ReadyLink concedes that
it previously litigated and lost its challenge to SCIF's decision to include per diem
amounts as payroll for the 2005 insurance year, but argues that it has never had the
opportunity to challenge whether SCIF otherwise properly calculated the premium
amount that it claims is due, pursuant to the terms of the contract between the parties, or
whether SCIF's past conduct, which ReadyLink alleges includes SCIF's acceptance of
ReadyLink's exclusions of its per diem payments from payroll in prior policy years and
SCIF's exclusion of per diem amounts in paying out on workers' compensation claims
filed by ReadyLink employees, might bar SCIF from being entitled to collect that
premium amount under the contract.
We agree with ReadyLink that the trial court erred in granting SCIF's motion for
judgment on the pleadings. A full review of the collateral administrative and judicial
proceedings demonstrates that ReadyLink and SCIF have not previously litigated the vast
majority of issues raised by SCIF's action seeking to collect additional premium amounts
5
from ReadyLink, and further reveals that those issues could not have been litigated in the
administrative action. We therefore reverse the judgment, as well as the court's
interlocutory order denying ReadyLink's motion to compel further discovery responses
from SCIF. We remand the matter for further proceedings.
II.
FACTUAL AND PROCEDURAL BACKGROUND
A. Factual background
1. Background regarding ReadyLink and its payments to its nurse employees
Appellant ReadyLink is a nurse staffing company based in Thousand Palms,
California. It contracts with registered nurses, licensed vocational nurses, and certified
nursing assistants from throughout the United States and places them at hospitals.
During the relevant time period, ReadyLink paid its nurses an hourly wage and,
with respect to its California nurses for whom the workers' compensation insurance is at
issue in this case, also paid a "per diem" amount. The per diem component that
ReadyLink relied on in paying its nurses was calculated using location-specific federal
tables, known as "CONUS" tables. ReadyLink pays the per diem to nurses as an
expense, which is taken from its general and administrative account, rather than as
payroll.
6
2. SCIF's role as ReadyLink's workers' compensation insurer
SCIF is a public enterprise fund, created pursuant to Insurance Code section 11770
et seq., as a workers' compensation insurer.3 In September 2000, ReadyLink applied for
workers' compensation insurance through SCIF, and SCIF issued a policy to ReadyLink.
ReadyLink's workers' compensation policy with SCIF was renewed annually until
ReadyLink cancelled its coverage with SCIF in February 2007.
Pursuant to the terms of the insurance policy, at the end of each policy year, SCIF
was permitted to audit ReadyLink's payroll records to determine the amount of wages
that ReadyLink had paid to its employees that year, and to use that amount to determine
the final premium owed. Workers' compensation insurers report the results of such audits
to the Workers' Compensation Insurance Rating Bureau (WCIRB), which uses the data
supplied to support its classification and rating systems. (ReadyLink Healthcare, supra,

3 As the court in ReadyLink Healthcare, Inc. v. Jones (2012) 210 Cal.App.4th 1166,
1169 (ReadyLink Healthcare) described it, "SCIF is a quasi-public company created by
the Legislature to ensure that mandatory workers' compensation insurance will be
available to California employers." By statute, SCIF is required to be "self-supporting"
and is to "be fairly competitive with other [workers' compensation] insurers." (Ins. Code,
§ 11775.)
7
210 Cal.App.4th at p. 1169.)4 SCIF conducted routine audits for ReadyLink's 2001,
2002, 2003, and 2004 policy years. In each of those years, SCIF did not question
ReadyLink's use of the per diem payment system, thereby essentially permitting
ReadyLink to exclude the per diem payments from its payroll calculation for purposes
determining the amount of its premium. According to a declaration submitted by
ReadyLink's Executive Vice President, during these policy years, SCIF paid out workers'
compensation benefits to ReadyLink's injured employees and excluded the per diem
amounts when calculating salary replacement.

4 Workers' compensation insurance is regulated by the Insurance Commissioner.
"Each workers' compensation insurer must report claims data to a rating organization
designated by the Insurance Commissioner. (§§ 11734, subd. (b), 11751.5.) 'To achieve
a uniform system for accurately recording and analyzing data, Insurance Code section
11751.5 authorizes the Insurance Commissioner to adopt "reasonable rules and statistical
plans" for reporting loss and expense information.' (Simi Corp. v. Garamendi [(2003)]
109 Cal.App.4th [1496,] 1500–1501.) To achieve this end, the Rating Bureau publishes
the California Workers' Compensation Uniform Statistical Reporting Plan—1995
([USRP]; available at [as
of Feb. 16, 2012]) and the California Workers' Compensation Experience Rating Plan—
1995 (Experience Rating Plan; available at org/wcirb/root/pdf/erp_ic_regs_only.pdf> [as of Feb. 16, 2012]). The plans are
compendia of administrative rules and regulations governing the issuance of workers'
compensation coverage by SCIF and other carriers. They set forth classifications, rates
and rating systems approved by the commissioner pursuant to sections 11658 and 11730
et seq. and have been incorporated by reference into the California Code of Regulations.
(Cal. Code Regs., tit. 10, §§ 2318.6, 2353.1.)" (Allied Interstate Inc. v. Sessions Payroll
Management, Inc. (2012) 203 Cal.App.4th 808, 818–819.)

3. SCIF's audit of the 2005 policy year and invoice for additional premiums
based on the inclusion of per diem payments as payroll
SCIF began its audit of ReadyLink's 2005 policy year in January 2007. During the
audit of the 2005 policy year, SCIF requested from ReadyLink information regarding its
per diem program. A senior auditor in SCIF's "[S]pecial [R]isk [D]ivision" had noticed
that ReadyLink was paying its nurses a minimum wage of approximately $6.75 an hour
and providing them with unusually high stipulated per diem amounts. This senior auditor
had conducted dozens of audits of nurse staffing agencies and registries and had never
before seen a nurse staffing agency pay more than 50 percent of its remuneration to
nurses in the form of per diem payments; nor had she seen a nurse staffing agency pay its
nurses hourly wages that were significantly below the average hourly rate that was
typically paid to nurses who were trained, licensed, and registered nurses in California.
(ReadyLink Healthcare, supra, 210 Cal.App.4th at 1170.) The auditor questioned
ReadyLink regarding its per diem payments and requested documentation to substantiate
that the per diem payments met the standards for such payments set forth in the USRP.
ReadyLink responded to SCIF's inquiries by stating that ReadyLink was in compliance
with federal per diem guidelines. ReadyLink provided no additional documentation to
SCIF regarding its per diem payment program.
SCIF provided ReadyLink with its final audit for the 2005 policy year in June
2007. The audit categorized ReadyLink's per diem payments to nurses during the policy
year as payroll for reporting purposes, and included the per diem amounts in calculating
ReadyLink's final premium for the policy year. SCIF determined that with the per diem
9
payments included as payroll, ReadyLink owed more than $550,0005 in additional
premium payments for the 2005 policy year.6
4. ReadyLink's appeal of SCIF's decision to include the per diem amount as
payroll in calculating ReadyLink's 2005 premium to the Department of
Insurance
ReadyLink disputed SCIF's decision to include the per diem amounts as payroll
under the USRP rules, and SCIF referred the dispute to its internal customer assistance
program. (ReadyLink Healthcare, supra, 210 Cal.App.4th at p. 1170.) SCIF's internal
customer assistance program "requested that ReadyLink provide 'verifiable
documentation' of the per diem payments, in the form of 'invoices, receipts and other
third-party paperwork' showing reimbursement for 'travel expenses, lodging, food
expenses, and the like.' " (Ibid.) "ReadyLink did not provide any documentation" in
response to this request. (Ibid.) In the absence of documentation to support ReadyLink's
assertion that the per diem payments were made to reimburse nurses for their travel
expenses while away from home, rather than having been made to compensate them for
their nursing services, SCIF's internal customer assistance program determined that the

5 In the breach of contract action from which this appeal arises, SCIF contends that
the amount of additional premium is $555,327.53. In an administrative decision issued
by an Administrative Law Judge (ALJ) and adopted by the Insurance Commissioner
arising from ReadyLink's appeal of SCIF inclusion of the per diem amounts as payroll in
its final audit—a decision that we discuss further below—the ALJ identifies the amount
of additional premium that SCIF was claiming as being due as $570,000.
6 Beginning in September 2007, the IRS began a tax audit of ReadyLink for tax
years 2004, 2005, and 2006. At the conclusion of that audit, the IRS tax auditor informed
ReadyLink that he "was proposing no changes to ReadyLink's tax return."
10
per diem amounts were properly included in the adjusted premium calculation for the
2005 policy year. (Ibid.)
In April 2008, ReadyLink appealed SCIF's audit decision to include per diem
amounts as payroll to the California Department of Insurance (DOI appeal).7 The issue

7 Although the ALJ's Proposed Decision states that ReadyLink filed its appeal
"pursuant to California Insurance Code section 11753.1," the trial court that decided
ReadyLink's subsequent petition for a writ of administrative mandamus states that
ReadyLink "appealed . . . to the California Department of Insurance's Administrative
Hearing Bureau, pursuant to California Insurance Code Section 11737(f)." On appeal,
ReadyLink suggests that it was proceeding pursuant to Insurance Code section 11753.1,
arguing that its appeal related to the "reclassification of per diem payments . . . [as]
payroll." (Italics omitted.) A document in the record that SCIF identified in the
underlying trial court proceeding in this case as being "ReadyLink's Administrative
Appeal" and that appears to be a letter dated June 2, 2008, from an attorney for
ReadyLink to the ALJ, does not identify any statutory provision as the basis for
ReadyLink's appeal of SCIF's decision regarding how to calculate payroll to the
Insurance Commissioner.
A review of the two provisions of the Insurance Code that are referenced in the
record as providing the basis for ReadyLink's administrative appeal does not definitively
clarify under which statutory provision ReadyLink proceeded, but does suggest that
subdivision (b) of section 11753.1 may provide the most applicable statutory basis for
ReadyLink's appeal to the Insurance Commissioner.
Insurance Code section 11753.1 provides in relevant part:
"(a) Any person aggrieved by any decision, action, or omission to
act of a rating organization may request that the rating organization
reconsider the decision, action, or omission. If the request for
reconsideration is rejected or is not acted upon within 30 days by the
rating organization, the person requesting reconsideration may,
within a reasonable time, appeal from the decision, action, or
omission of the rating organization. The appeal shall be made to the
commissioner by filing a written complaint and request for a hearing
specifying the grounds relied upon. . . .
"(b) Any insurer adopting a change in the classification assignment
of an employer that results in an increased premium shall notify the
employer in writing . . . . Any employer receiving this notice shall
11
to be decided in that appeal, as stated by the ALJ, was: "For policy year 2005, did SCIF
properly include per diem payments made to registry nurses as 'payroll' or 'remuneration'
pursuant to USRP, Part 3, Section V?" As explained by the ALJ, the USRP defines per
diem payments as "reimbursement for additional living expense by virtue of job
location." The ALJ further explained that these amounts "shall not be considered payroll
if 'the amount is reasonable and the employer's records show that the employee worked at
a job location that would have required the employee to incur additional expenses not
normally assumed by the employee.' " The ALJ noted that whether SCIF could properly
include ReadyLink's per diem payments as payroll constituted a question of first
impression.
The DOI appeal proceeded through discovery, and the ALJ conducted a three-day
hearing on March 25–27, 2009. After the hearing, and after considering the parties'

have the right to request reconsideration and appeal the
reclassification pursuant to this section."
Insurance Code section 11737, subdivision (f) provides in relevant part:
"(f) Every insurer or rating organization shall provide within this
state reasonable means whereby any person aggrieved by the
application of its filings may be heard by the insurer or rating
organization on written request to review the manner in which the
rating system has been applied in connection with the insurance
afforded or offered. . . . Any party affected by the action of the
insurer or rating organization on the request may appeal, within 30
days after written notice of the action, to the commissioner who,
after a hearing held within 60 days from the date on which the party
requests the appeal, or longer upon agreement of the parties and not
less than 10 days' written notice to the appellant and to the insurer or
rating organization, may affirm, modify, or reverse that action. . . ."
12
posthearing briefing, the ALJ issued a 40-page Proposed Decision, dated August 6, 2009.
In the Proposed Decision, the ALJ stated, among other things:
"Appellant [ReadyLink] has not met its burden of proof to show
SCIF's 2005 payroll calculations were improper with regard to the
inclusion of per diem monies. More specifically, Appellant failed to
prove the per diem amounts paid to its employees were 'reasonable'
and further failed to prove the nurses worked in locations that
required them to incur additional expenses not normally assumed."
In reaching this conclusion, the ALJ specifically found that of the 259 nurses
ReadyLink employed during the 2005 policy year, 142 of them lived within 50 miles of
the hospitals to which they had been assigned, and as to the remaining 117, there was an
absence of "any facts demonstrating [that] these 117 employees actually had a separate
residence or that they incurred duplicate living expenses while in ReadyLink's employ as
required by the plain language of the USRP."8 Thus, "all per diem payments made to
[the 142 nurses who lived within 50 miles of their assignments] are properly considered
payroll for premium calculation purposes" and "all per diem payments made to [the
remaining 117 nurses for whom there was no demonstration of the incurring of duplicate
living expenses] must be included in ReadyLink's payroll calculation for workers'
compensation purposes."
The ALJ's Proposed Decision concluded with the following one-sentence order,
"SCIF's decision regarding the 2005 policy year audit is affirmed."

8 The ALJ noted that a "taxpayer [who] continuously travels and thus does not
duplicate substantial, continuous living expenses for a permanent home . . . may be
considered 'itinerant' and thus ineligible for any travel deductions."
13
The Insurance Commissioner adopted the ALJ's Proposed Decision and designated
the decision as "precedential" by way of an order filed September 30, 2009.
5. ReadyLink's petition for writ of administrative mandamus in the Superior
Court and its appeal of the trial court's denial of its petition
ReadyLink sought judicial review of the Insurance Commissioner's decision by
petitioning the superior court for a peremptory writ of administrative mandamus under
Code of Civil Procedure section 1094.5. In its petition, ReadyLink argued: "(1) the
Commissioner exceeded his authority by effectively promulgating a 'new' regulation
without proceeding through the required public hearing process; (2) the new rule was
improperly applied retroactively to ReadyLink; and (3) the Commissioner failed to
recognize that the IRS regulations [regarding per diem payments] are presumptively
reasonable." (ReadyLink Healthcare, supra, 210 Cal.App.4th at p. 1172.)
The trial court issued a 10-page ruling denying ReadyLink's petition. (ReadyLink
Healthcare, supra, 210 Cal.App.4th at p. 1172.) ReadyLink appealed the trial court's
denial of the petition to the Second District Court of Appeal. (Ibid.)
The appellate court affirmed the trial court's ruling denying ReadyLink's petition
for a peremptory writ of administrative mandamus. (ReadyLink Healthcare, supra, 210
Cal.App.4th at p. 1180.) In reviewing the trial court's judgment, the appellate court
concluded that (1) the trial court had applied the correct standard of review in considering
ReadyLink's writ petition; (2) the Insurance Commissioner's decision was not preempted
by federal tax law, as ReadyLink had argued for the first time on appeal; (3) the
Insurance Commissioner's decision did not constitute a "new regulation" for which notice
14
and a public hearing would be required because the Insurance Commissioner had merely
"interpreted the USRP's subsistence payments rule to determine whether ReadyLink's per
diem payments constituted payroll"; and (4) the equitable considerations that ReadyLink
raised did not prevent the "retroactive" application of the Insurance Commissioner's
decision to a prior policy year. (Id. at pp. 1172–1179.)
6. ReadyLink's separate federal action
While ReadyLink's appeal from the trial court's denial of its petition for a
peremptory writ of administrative mandamus was pending, ReadyLink filed a putative
class action lawsuit in federal district court against SCIF and the Insurance
Commissioner. ReadyLink's "federal complaint alleged that IRS regulations preempted
the [Insurance] Commissioner's decision, requested both declaratory and injunctive relief,
and asserted various state-law damage claims." (ReadyLink Healthcare, Inc. v. State
Compensation Ins. Fund (9th Cir. 2014) 754 F.3d 754, 757.)
The federal district court issued an order granting the defendants' motions to
dismiss, concluding that with respect to ReadyLink's request for declaratory and
injunctive relief based on federal preemption, the requirements for abstention were met
under Younger v. Harris (1971) 401 U.S. 37 (Younger), and, further concluding that it
was appropriate to decline to exercise supplemental jurisdiction over the remaining statelaw claims. (ReadyLink Healthcare, Inc. v. State Compensation Ins. Fund, supra, 754
F.3d at p. 757.)
ReadyLink appealed the federal district court's judgment to the Ninth Circuit
Court of Appeals. (ReadyLink Healthcare, Inc. v. State Compensation Ins. Fund, supra,
15
754 F.3d at p. 756.) While ReadyLink's federal appeal was pending, California's Second
District Court of Appeal issued its opinion in ReadyLink Healthcare, supra, 210
Cal.App.4th 1166, and the California Supreme Court denied review (ibid.), rendering the
Second District's opinion final.
In providing background relevant to its determination of ReadyLink's appeal, the
Ninth Circuit described what had occurred in ReadyLink's appeal of SCIF's decision to
include the per diem amounts in the calculation of payroll to the Insurance Commissioner
as follows:
"When SCIF audited ReadyLink for the 2005 policy year, it found
that ReadyLink had failed to report certain per diem payments to
employees as payroll, and billed ReadyLink for an additional
premium of $555,327.53. ReadyLink appealed that decision to the
California Department of Insurance, see Cal. Ins. Code § 11737(f),
and an administrative law judge (ALJ) approved SCIF's premium
calculation." (ReadyLink Healthcare, Inc. v. State Compensation
Ins. Fund, supra,754 F.3d at p. 757, italics omitted.)
In the sections of the opinion discussing whether the federal district court was
correct in dismissing ReadyLink's complaint, the Ninth Circuit considered and decided
two issues: (1) Had the district court properly abstained from adjudicating ReadyLink's
federal preemption argument on Younger abstention grounds? and (2) Given the issuance
of an opinion by the California Second District Court of Appeal's during the intervening
time, in which the state appellate court rejected ReadyLink's federal preemption
argument, did principles of issue preclusion bar ReadyLink's claim for declaratory relief?
(ReadyLink Healthcare, Inc. v. State Compensation Ins. Fund, supra, 754 F.3d at pp.
757–760, 760–762.) The Ninth Circuit determined that the district court had erred in
16
abstaining from adjudicating the federal preemption argument, but that ReadyLink was
barred by the doctrine of issue preclusion from litigating its claim for declaratory relief.
(Ibid.)
B. Procedural background
1. SCIF's complaint and ReadyLink's answer
SCIF filed the action underlying this appeal in Riverside County Superior Court
on January 13, 2015. SCIF alleged causes of action against ReadyLink for breach of
contract, money due on an open book, and common count.9
According to SCIF's complaint, ReadyLink entered into a written insurance
contract with SCIF that was effective between September 1, 2005 and September 1, 2006.
SCIF alleged that ReadyLink had breached the insurance contract by 1) failing to
accurately report all of its payroll, in that it had improperly characterized some of its
payroll as expense reimbursement; and 2) failing to pay SCIF the full premium when due
under the policy, as established pursuant to SCIF's audit of the 2005 payroll records.
SCIF sought damages in the amount of $555,327.53, plus prejudgment interest at the
legal rate.
ReadyLink filed its answer to SCIF's complaint in March 2015. The answer
included a general denial and asserted nine affirmative defenses: failure to state a cause

9 In its briefing on appeal, SCIF refers to the underlying action as its "collection
case."
17
of action, statute of limitations, waiver, estoppel, speculative damages, laches,
ratification, unclean hands, and accord and satisfaction.10
2. SCIF's Initial Motion for Judgment on the Pleadings
In August 2016, SCIF filed a motion for judgment on the pleadings. SCIF argued
that ReadyLink's "boilerplate" affirmative defenses had not been properly stated because
ReadyLink had failed to allege any facts to support them. SCIF further argued that these
defenses were barred by principles of collateral estoppel and res judicata. SCIF requested
that the trial court grant its motion for judgment on the pleadings, specifically with
respect to ReadyLink's affirmative defenses, without leave to amend.
After a hearing on September 9, 2016, the trial court granted SCIF's motion for
judgment on the pleadings. The trial court concluded that the affirmative defenses, as
stated in the answer, "fail[ed] to state facts sufficient to constitute a defense." However,
the court granted ReadyLink leave to amend its answer. The trial court concluded that
"[t]he claim preclusion aspect of res judicata does not apply because issues raised in the
underlying actions concerned the Insurance Commissioner's determination that per diem
payments were properly considered payroll while the issue in this action is whether the
failure to pay the $555,327.53 is a breach of the parties' contract." The court was unsure
whether "the issue preclusion aspect of res judicata, otherwise referred to as collateral

10 Pursuant to a meet and confer between the attorneys for the parties, ReadyLink
apparently agreed to withdraw four of its affirmative defenses—failure to state a cause of
action, statute of limitations, laches, and speculative damages.
18
estoppel, may apply." However, because ReadyLink's answer failed to allege the facts
necessary for the court to "analyze the effect of collateral estoppel," the court permitted
ReadyLink to file an amended answer.
3. ReadyLink's first amended answer and subsequent proceedings
ReadyLink filed a first amended answer on September 14, 2016 in which it
asserted six affirmative defenses—estoppel, ratification, fraud, unclean hands, waiver,
and conflict with Insurance Code section 381. The first amended answer detailed the
facts supporting these affirmative defenses, including allegations that at the time it first
purchased insurance from SCIF, ReadyLink had informed SCIF "about its compensation
structure and fully disclosed its per diem to SCIF" (italics omitted), that SCIF had
conducted multiple audits in prior policy years in which it had said nothing about
ReadyLink's per diem payment structure and had not included per diem payments as
payroll, that SCIF had previously calculated ReadyLink's annual premiums with
knowledge of ReadyLink's per diem payment structure, and that ReadyLink had relied on
SCIF's representations about the amount of premium that ReadyLink would be charged in
deciding to purchase workers' compensation insurance from SCIF.
Just after ReadyLink filed its original answer, it commenced discovery by serving
Requests to Produce, Requests for Admission, Special Interrogatories, and Form
Interrogatories on SCIF. Unhappy with what ReadyLink believed were "non-responsive"
discovery responses from SCIF, and after meeting and conferring with SCIF's counsel,
ReadyLink filed motions to compel further responses to its Requests to Produce, Form
Interrogatories, and Special Interrogatories on November 8, 2016.
19
The trial court heard ReadyLink's motions to compel on March 15, 2017. The
court denied all three motions on collateral estoppel grounds, stating, "It is clear from
ReadyLink's Amended Answer that it seeks to relitigate the exact same issues already
addressed before the Insurance Commission[er] and the Court of Appeal. Each of the
assertions that ReadyLink makes in its Amended Answer were either expressly or
implicitly addressed and rejected by the [C]ourt of [A]ppeal and cannot be relitigated in
this action. The discovery sought by ReadyLink is to support their non-defensible
affirmative defenses, which they are collaterally estopped from asserting in this action
and therefore not relevant to this litigation. Accordingly, the court denies the motions in
their entirety."11
4. SCIF'S second motion for judgment on the pleadings
On August 3, 2017, SCIF filed a motion for judgment on the pleadings directed to
ReadyLink's first amended answer. The motion asserted generally that the "Amended
Answer does not state facts sufficient to constitute a defense to the complaint" and that
"ReadyLink is collaterally estopped from asserting all of the affirmative defenses
alleged." SCIF further claimed that "[t]he parties litigated on the merits all of the issues
surrounding State Fund's attempts to enforce the terms of the insurance policy contract
between State Fund and Readylink for the 2005 policy year four times- prior [to] the
present collection action- resulting in three published decisions." (Italics omitted.)

11 ReadyLink filed a petition for writ of mandate in this court after the trial court
denied its motions to compel; this court summarily denied the petition.
20
As to each affirmative defense asserted in ReadyLink's first amended answer,
SCIF relied on language from the appellate court's opinion in ReadyLink Healthcare,
supra, 210 Cal.App.4th 1166 to demonstrate that the issues underlying ReadyLink's
affirmative defenses had been rejected by that court. For example, SCIF relied on the
appellate court's statement that "[the fact t]hat a sole IRS auditor or prior SCIF auditors
did not discover that ReadyLink's per diem payments could not be substantiated is not
evidence that ReadyLink's practices were correct or that it reasonably believed them to be
correct." (Id. at p. 1179.) According to SCIF, this statement by the appellate court
demonstrated that "ReadyLink's reliance [on SCIF's prior audits] was not reasonable."
SCIF also asserted that, "[a]s noted in ¶8 of the complaint, and repeatedly during this
lawsuit, the parties litigated the issue of State Fund's damages in this matter at every
possible level."12
ReadyLink filed an opposition to SCIF's motion for judgment on the pleadings. In
its opposition, ReadyLink contended that SCIF's pleadings failed to "sufficiently establish
damages," by failing "to plead with particularity the contract terms giving rise to the
amount owed." ReadyLink asserted that SCIF's reliance on the policy provision that

12 Paragraph 8 of SCIF's Complaint states: "State Fund's decision regarding the
policy audit, and as such the premium bill for $555,327.53, was affirmed by the
California Insurance Commissioner, Court of Appeal of California, Second Appellate
District, and became final upon the California Supreme Court's denial of certiorari [sic].
Moreover, the federal court's dismissal of ReadyLink's related federal complaint was
affirmed by the United States Court of Appeals for the Ninth Circuit based on issue
preclusion."
21
states, " 'All premiums for this policy will be determined by our manuals of rules, rates,
rating plans and classifications' " (boldface & italics omitted) was insufficient to establish
damages because none of the "pertinent language of its manuals" was set forth in the
complaint. ReadyLink also argued that it had never been provided the opportunity to
litigate its affirmative defenses in any of the prior actions, and that in fact, it could not
have litigated the issues raised by its affirmative defenses in the prior proceedings
"because they were not relevant to the narrow issues decided in the prior proceedings."
For example, ReadyLink noted that with respect to its affirmative defense of fraud, it had
alleged that its decision to purchase insurance from SCIF was based on representations
by SCIF that it would base its premium calculations on ReadyLink's accounting methods
regarding its per diem program, which, ReadyLink further alleged, had been fully
disclosed to SCIF prior to the inception of any of the policies SCIF issued to ReadyLink.
ReadyLink also noted that "[t]here have been no express findings on the defenses
ReadyLink raises in this case," and further argued that "[i]f these issues had been
decided, SCIF would not have filed this action," suggesting that SCIF would not have
had to file a breach of contract action if the issues raised in ReadyLink's affirmative
defenses had in fact previously been litigated and determined.
The trial court held a hearing on SCIF's second motion for judgment on the
pleadings on September 22, 2017. During argument on the motion, the trial court asked
ReadyLink's counsel, "Didn't the United States Court of Appeal[s] confirm an issue that
was litigated and/or, to use your words, could have been litigated regarding the premium
calculation? And the Court said, quote, 'And an administrative law judge approved
22
SCIF's premium calculation.' That can only be fairly interpreted to mean that [what] the
administrative law judge, at least so far as the U.S. Court of Appeal[s] for the Ninth
Circuit [was concerned], determined[,] was a premium calculation and amount."
ReadyLink's counsel attempted to explain that "it never was adjudicated in terms of the
exact precise amount which was owed."
The trial court ultimately granted SCIF's second motion for judgment on the
pleadings. In its written order, the court concluded that principles of issue preclusion
prevented ReadyLink from relitigating the issue of the amount of premium that
ReadyLink owed to SCIF for the 2005 policy year, stating, "This action was necessary to
reduce SCIF's claim to the premium owed to a judgment. The amount owed is precisely
what was determined in the underlying administrative decision and appeals." The court
noted in its order that SCIF was seeking "to recover $555,327.53 in premiums for 2005."
The court did not mention prejudgment interest.
5. Entry of judgment and ReadyLink's motion to vacate the judgment
SCIF's counsel served ReadyLink's counsel with a proposed judgment on October
11, 2017. SCIF had failed to provide ReadyLink with the required 10 days to make
objections, as required by California Rules of Court, rule 3.1590(j), submitting its
proposed judgment to the court just five days after the trial court issued its ruling.
ReadyLink filed an objection to the proposed judgment on October 19, 2017; however,
the trial court had already signed the proposed judgment on October 16.
The judgment signed by the court included interest on the judgment at the rate of
10 percent per annum dating from July 30, 2007. However, the issue of SCIF's
23
entitlement to prejudgment interest had not been addressed prior to that point in time. On
October 24, 2017, ReadyLink filed a motion to vacate the judgment, arguing that the
judgment impermissibly included prejudgment interest, which was not available under
Civil Code section 3287, given that the parties had required the assistance of the court in
fixing SCIF's damages.13
SCIF argued in opposition to ReadyLink's motion to vacate the judgment that the
premium amount owed by ReadyLink was "established to a legal certainty" as a result of
the single sentence in the Ninth Circuit Court of Appeals' opinion describing the prior
history of the related administrative action before the Insurance Commissioner and
reviewed by California state trial and appellate courts. SCIF further argued that the
amount of damages became fixed when ReadyLink withdrew its affirmative defense of
"speculative damages."

13 Civil Code section 3287 reads in relevant part: "(a) A person who is entitled to
recover damages certain, or capable of being made certain by calculation, and the right to
recover which is vested in the person upon a particular day, is entitled also to recover
interest thereon from that day . . . ."
" ' "Damages are deemed certain or capable of being made certain within the
provisions of subdivision (a) of section 3287 where there is essentially no dispute
between the parties concerning the basis of computation of damages if any are
recoverable but where their dispute centers on the issue of liability giving rise to
damage." [Citations].' [Citation.] Thus, ' " '[t]he test for recovery of prejudgment
interest under [Civil Code] section 3287, subdivision (a) is whether defendant actually
know[s] the amount owed or from reasonably available information could the defendant
have computed that amount. [Citation.]' [Citations.]" ' " (Duale v. Mercedes-Benz USA,
LLC (2007) 148 Cal.App.4th 718, 729.)
24
In denying ReadyLink's motion to vacate the judgment, the trial court rejected
ReadyLink's objections to the judgment, stating that the "objections are not well
founded."
The trial court entered judgment on October 16, 2017. The judgment awarded
SCIF $555,327.53 "for the 2005 premium bill issued by Plaintiff on June 29, 2007" and
awarded another $571,606.99 in prejudgment interest for the time period between July
30, 2007 and October 11, 2017.
SCIF filed notice of entry of judgment on ReadyLink on November 30, 2017.
ReadyLink filed a timely notice of appeal from the judgment.
III.
DISCUSSION
A. Three requests for judicial notice
While this appeal was pending, the parties filed three requests for judicial notice
with this court. As an initial matter, we address these requests for judicial notice.
1. ReadyLink's request for judicial notice filed June 15, 2018
On June 15, 2018, ReadyLink filed a request that this court take judicial notice of
"the State Compensation Insurance Fund 'Workers' Compensation Insurance — Rate
25
Filing Form' with the Department of Insurance for the year 2005, filed June 1, 2005."14
SCIF did not oppose ReadyLink's request for judicial notice of this document.
Although no opposition was filed to ReadyLink's request for judicial notice of
certain portions of SCIF's 2005 rate filing, we deny the request on the ground that the
materials are not relevant to our determination of the issues on appeal. (See Mangini v.
R. J. Reynolds Tobacco Co. (1994) 7 Cal.4th 1057, 1063 (Mangini) [only relevant
material is subject to judicial notice], overruled on other grounds by In re Tobacco Cases
II (2007) 41 Cal.4th 1257.)
2. SCIF's request for judicial notice filed October 16, 2018 and its related
request for judicial notice filed November 21, 2018
On October 16, 2018, SCIF filed a request for judicial notice and sought judicial
notice of the following documents and records:
"1. Exhibit A-Transcript of Hearing, Riverside County Superior
Court Case No. PSC 1500168 State Compensation Insurance Fund
v. ReadyLink Healthcare, Inc., Reporter's Transcript of Motion for
Judgment on the Pleadings, Before the Honorable David M.
Chapman September 22, 2017.
"2. Exhibit B-Supplemental Brief in Support of Petitioner
ReadyLink Healthcare, Inc.'s Petition for Writ of Administrative
Mandamus, submitted to the Los Angeles Superior Court, in case
No. BS 124590, ReadyLink Healthcare, Inc. v. Steve Poizner, et al.
served on January 31, 2011 to be heard April 14, 2011.

14 The supporting declaration filed with the request for judicial notice indicates that
ReadyLink seeks to "attach[ ] only those portions relevant to this appeal and cited in
Appellant's Opening Brief," and is therefore seeking judicial notice of only some portions
of the 200-page filing form.
26
"3. Exhibit C-State Compensation Insurance Fund's Discovery
Request, filed with the Insurance Commissioner of the State of
California on September 12, 2008, In the Matter of the Appeal of
ReadyLink Healthcare, Inc., Case No. AHB-WCA-08-14, and
Appellant's Objections to SCIF's Discovery Request.
"4. Exhibit D-The California Department of Insurance
Commissioner's Precedential Decision In the Matter of the Appeal of
Advanced Fuel Filtration Systems[ ] (5/21/04) AHB-WCA-03-45.
"5. Exhibit E-The California Department of Insurance
Commissioner's Precedential Decision In the Matter of the Appeal of
E M Machining (11/29/01) File No. ALB –WCA-00-30.
"6. Exhibit F-Excerpt from Rassp & Herlick, California Workers'
Compensation Law § 3.11 Insurance Premiums. [8] EmployerInsurer Disputes.
"7. Exhibit G-Excerpt from Levine on California Workers'
Compensation Premium and Insurance, Copyright 2006, by
International Risk Management Institute, Inc., p. 6.D.3."
On November 21, 2018, SCIF filed a second request for judicial notice that it
identified as an "abridged request [for judicial notice filed] concurrently with its brief."
(Italics added.) In the document, SCIF requested that this court take judicial notice of the
same documents for which it had sought judicial notice in its previous request for judicial
27
notice, with the exception of the first document, the "Transcript of Hearing, Riverside
County Superior Court Case No. PSC 1500168."15
ReadyLink filed oppositions to both requests for judicial notice.
We grant SCIF's request for judicial notice of the following two documents,
pursuant to Evidence Code section 452, subdivision (c), which permits a court to take
judicial notice of the "[o]fficial acts of the legislative, executive, and judicial departments
of the United States and of any state of the United States":
(1) "The California Department of Insurance Commissioner's
Precedential Decision In the Matter of the Appeal of Advanced Fuel
Filtration Systems[ ] (5/21/04) AHB-WCA-03-45."
(2) "The California Department of Insurance Commissioner's
Precedential Decision In the Matter of the Appeal of E M Machining
(11/29/01) File No. ALB –WCA-00-30."

15 SCIF indicated that the transcript at issue was already part of the record on appeal.
As a result of SCIF eliminating what had been the document identified as "Exhibit A" in
its October 16, 2018 request for judicial notice, each document listed in its November 21,
2018 request for judicial notice bears a different exhibit letter from the exhibit letter in
the October filing. For example, what had been "Exhibit B" in the October 16, 2018
request for judicial notice, bears the title "Exhibit A" in the November 21, 2018 request
for judicial notice. Because of the confusion that may be caused by this labeling, in
addressing these documents here, we will refer to each exhibit by the title that SCIF used
(e.g., "Supplemental Brief in Support of Petitioner ReadyLink Healthcare, Inc.'s Petition
for Writ of Administrative Mandamus, submitted to the Los Angeles Superior Court, in
case No. BS 124590, ReadyLink Healthcare, Inc. v. Steve Poizner, et al. served on
January 31, 2011 to be heard April 14, 2011") rather than by their "Exhibit" indicators
(e.g., "Exhibit A").
28
We deny SCIF's request for judicial notice of the remaining materials on the
ground that they are not relevant to our determination of the issues on appeal (see
Mangini, supra, 7 Cal.4th at p. 1063).
B. The trial court erred in granting SCIF's motion for judgment on the pleadings
ReadyLink challenges the trial court's decision to grant SCIF's motion for
judgment on the pleadings, based on the court's stated conclusion that "[r]es judicata bars
relitigation of the determination of the premium owed" (boldface & underscoring
omitted). According to ReadyLink, the issues in this case are not "identical to" the issues
in the prior administrative proceeding. ReadyLink contends that "while the ALJ ruled on
how ReadyLink's per diem payments would be classified for workers' compensation
premium purposes, no decision has ever touched on the amount of premium to which
SCIF would be entitled" (second italics added). ReadyLink further contends that "[t]he
prior litigation between the parties did not actually or necessarily decide SCIF's
entitlement to damages" (bolding & some capitalization omitted). ReadyLink notes that
most of the factual issues that must be determined with respect to SCIF's breach of
contract claim against ReadyLink are issues that are distinct from the issues that were
considered and decided in the administrative proceeding, the writ of administrative
mandamus proceeding and appeal, and the separate federal proceeding, and include
issues such as: (1) "Did SCIF fully perform under the contract of insurance"; (2) "Did
ReadyLink breach by failing to pay premiums when due"; (3) "Did SCIF suffer damages
as a result of any breach"; (4) "If [SCIF did suffer damages], what [is the] amount of
29
those damages" (italics added); and "Do any affirmative defenses apply to eliminate or
reduce ReadyLink's liability."16
In response, SCIF asserts that the "audit clearly established the amount of
premium owed" (boldface & some capitalization omitted) by ReadyLink. SCIF further
contends that ReadyLink "argued exhaustive facts and contentions regarding all of its
affirmative defenses in the prior litigation," such that it either previously litigated all of
the issues relevant to its affirmative defenses or was required to have raised the issues
with the Insurance Commissioner and failed to do so, thereby barring it from relitigating
these issues in this action.
To determine whether, as the trial court concluded, principles of issue preclusion
bar ReadyLink from litigating issues raised by SCIF's claims or the six affirmative
defenses that ReadyLink raised in its first amended answer, we must examine the
doctrines of res judicata and collateral estoppel, and the relationship of those principles to
the administrative hearing and the subsequent judicial review of that administrative
hearing, as well as the separate federal action. We then apply the preclusion doctrines to

16 We understand from ReadyLink's arguments presented on appeal and its
arguments made before the trial court that it seeks to hold SCIF to its burden to prove the
amount of damages it claims to have suffered in order to prevail on its breach of contract
claim by having SCIF demonstrate the accuracy of its premium calculation—in other
words, to have SCIF demonstrate that it used the correct inputs and applied the correct
calculations in coming up with the final premium amount. ReadyLink fully concedes that
it cannot challenge whether SCIF properly included per diem payments as payroll for
purposes of calculating the premium amount, since that issue was litigated and
determined in the prior proceedings.
30
determine whether the trial court was correct in concluding that the "amount owed" by
ReadyLink under the parties' contract was "determined in the underlying administrative
decision and appeals."
1. Relevant legal standards on review from judgment on the pleadings
A plaintiff is entitled to judgment on the pleadings if its complaint states a cause
of action against the defendant and the defendant's answer does not state facts sufficient
to constitute a defense. (Code Civ. Proc., § 438, subd. (c)(1)(A), (3)(A).)17 " 'A motion
for judgment on the pleadings, like a general demurrer, tests the allegations of the
[pleadings at issue], supplemented by any matter of which the trial court takes judicial
notice, to determine whether [the party] has stated a cause of action. [Citation.] Because
the trial court's determination is made as a matter of law, we review the ruling de novo,
assuming the truth of all material facts properly pled.' " (Angelucci v. Century Supper
Club (2007) 41 Cal.4th 160, 166 (Angelucci).)
2. Preclusion doctrines
"As generally understood, '[t]he doctrine of res judicata gives certain conclusive
effect to a former judgment in subsequent litigation involving the same controversy.' "
(People v. Barragan (2004) 32 Cal.4th 236, 252 (Barragan), italics omitted.) " 'In its
primary aspect,' commonly known as claim preclusion, [res judicata] 'operates as a bar to

17 Conversely, a defendant is entitled to judgment on the pleadings if the complaint
does not state a cause of action against the defendant. (Code Civ. Proc., § 438, subd.
(c)(1)(B), (3)(B).)
31
the maintenance of a second suit between the same parties on the same cause of action.
[Citation.]' [Citation.] 'In its secondary aspect,' commonly known as collateral estoppel,
'[t]he prior judgment . . . "operates" ' in 'a second suit . . . based on a different cause of
action . . . "as an estoppel or conclusive adjudication as to such issues in the second
action as were actually litigated and determined in the first action." ' " (Id. at pp. 252–
253.)
" 'The doctrine of res judicata, whether applied as a total bar to further litigation or
as collateral estoppel, "rests upon the sound policy of limiting litigation by preventing a
party who has had one fair adversary hearing on an issue from again drawing it into
controversy and subjecting the other party to further expense in its reexamination." '
[Citations.]" (Bucur v. Ahmad (2016) 244 Cal.App.4th 175, 185.) Res judicata promotes
judicial economy by precluding parties from engaging in the type of piecemeal litigation
that may occur if a single cause of action is split into more than one lawsuit or if a
particular issue has already been decided in an earlier lawsuit. (Mycogen Corp. v.
Monsanto Co. (2002) 28 Cal.4th 888, 897 (Mycogen).)
Although the res judicata doctrine encompasses both claim and issue preclusion,
the term "res judicata" has sometimes been used by California courts to denote claim
preclusion, while the term "collateral estoppel" has been used to refer to issue preclusion.
(See Mycogen, supra, 28 Cal.4th at p. 896, fn. 7.) Given that "res judicata" has
sometimes been used to refer to claim preclusion and at other times has been used in a
broader sense to refer to both claim and issue preclusion, or even issue preclusion, only,
(see DKN Holdings LLC v. Faerber (2015) 61 Cal.4th 813, 824 (DKN Holdings)), we
32
will adopt the labels employed by the Supreme Court in DKN Holdings and will "use the
terms 'claim preclusion' to describe the primary aspect of the res judicata doctrine and
'issue preclusion' to encompass the notion of collateral estoppel." (Ibid.)
" 'The prerequisite elements for applying the doctrine [of preclusion] to either an
entire cause of action or one or more issues are the same: (1) A claim or issue raised in
the present action is identical to a claim or issue litigated in a prior proceeding; (2) the
prior proceeding resulted in a final judgment on the merits; and (3) the party against
whom the doctrine is being asserted was a party or in privity with a party to the prior
proceeding.' " (Barragan, supra, 32 Cal.4th at p. 253.) However, there are some
differences.
"Claim preclusion 'prevents relitigation of the same cause of action in a second
suit between the same parties or parties in privity with them.' [Citation.] Claim
preclusion arises if a second suit involves (1) the same cause of action (2) between the
same parties (3) after a final judgment on the merits in the first suit. [Citations.] If claim
preclusion is established, it operates to bar relitigation of the claim altogether." (DKN
Holdings, supra, 61 Cal.4th at p. 824.) California courts apply the "primary rights"
theory in assessing whether two proceedings involve identical causes of action. (See
Mycogen, supra, 28 Cal.4th at p. 904.) "The plaintiff's primary right is the right to be
free from a particular injury, regardless of the legal theory on which liability for the
injury is based. [Citation.] The scope of the primary right therefore depends on how the
injury is defined. A cause of action comprises the plaintiff's primary right, the
defendant's corresponding primary duty, and the defendant's wrongful act in breach of
33
that duty." (Federation of Hillside & Canyon Assns. v. City of Los Angeles (2004) 126
Cal.App.4th 1180, 1202.)18 Additionally, " '[i]f the matter was within the scope of the
action, related to the subject-matter and relevant to the issues, so that it could have been
raised, the judgment is conclusive on it despite the fact that it was not in fact expressly
pleaded or otherwise urged . . . . A party cannot by negligence or design withhold issues
and litigate them in consecutive actions. Hence the rule is that the prior judgment
[constitutes claim preclusion] on matters which were raised or could have been raised, on
matters litigated or litigable.' " (Aerojet-General Corp. v. American Excess Ins. Co.
(2002) 97 Cal.App.4th 387, 402, italics omitted.)
"Issue preclusion prohibits the relitigation of issues argued and decided in a
previous case, even if the second suit raises different causes of action. [Citation.]" (DKN
Holdings, supra, 61 Cal.4th at p. 824.) "[I]ssue preclusion applies (1) after final
adjudication (2) of an identical issue (3) actually litigated and necessarily decided in the
first suit[19] and (4) asserted against one who was a party in the first suit or one in privity
with that party. [Citations.]" (DKN Holdings, supra, at p. 825.) If all four of the

18 A primary right is distinct from the legal theory on which liability is premised or
the remedies that may be sought. Thus, while a primary right may support multiple
theories of liability or various forms of relief, it gives rise to a single, indivisible cause of
action for purposes of applying claim preclusion principles. (Mycogen, supra, 28 Cal.4th
at p. 904.)
19 "For purposes of [issue preclusion], an issue was actually litigated in a prior
proceeding if it was properly raised, submitted for determination, and determined in that
proceeding." (Hernandez v. City of Pomona (2009) 46 Cal.4th 501, 511.)
34
requirements for issue preclusion are satisfied, a court then also determines whether
application of preclusion would be consistent with the "preservation of the integrity of the
judicial system, promotion of judicial economy, and protection of litigants from
harassment by vexatious litigation." (Lucido v. Superior Court (1990) 51 Cal.3d 335.)
The "party who asserts claim or issue preclusion as a bar to further litigation bears
the burden of proving that the requirements of the doctrine are satisfied." (Hong Sang
Market, Inc. v. Peng (2018) 20 Cal.App.5th 474, 489 (Hong Sang).)
3. Analysis
Although SCIF's briefing is somewhat confusing on this point, SCIF appears to
contend that the administrative proceeding conclusively determined the amount that
ReadyLink owes to SCIF under the contract (as the trial court apparently concluded when
it stated that "[t]he amount owed is precisely what was determined in the underlying
administrative decision"), or, in the alternative, that to the extent that the ALJ did not
decide the amount of premium due, the ALJ's failure to do so resulted from ReadyLink's
35
failure to pursue or exhaust its administrative remedies.20 We disagree with both
contentions.
a. The issues raised by the complaint and ReadyLink's first amended
answer are not identical to the issues determined in those prior
proceedings
SCIF maintains that ReadyLink "argued exhaustive facts and contentions
regarding all of its affirmative defenses in the prior litigation." However, SCIF does not
identify which "facts" or "contentions" it believes ReadyLink previously argued that
would bar its affirmative defenses and entitle SCIF to a judgment on its breach of
contract claim in this action, and also fails to identify where in the administrative record,
or in the record of any prior court proceeding, those facts or contentions were actually
raised.

20 In making its arguments on appeal, SCIF seemingly mixes and conflates the
separate doctrines of issue preclusion, claim preclusion, and administrative exhaustion
without drawing the necessary connections between or among the doctrines. For
example, SCIF contends that ReadyLink was required to "first exhaust administrative
remedies" when "seeking relief from excessive surcharges," and that ReadyLink "knew it
had the duty to raise this issue [i.e., presumably the amount of the premium due] at the
administrative hearing" in arguing that the trial court's ruling on the motion for judgment
on the pleadings was correct. The exhaustion of administrative remedies doctrine
provides a basis for a court to decline to act when requested by a plaintiff where that
plaintiff has not first sought relief from the administrative agency. Without fully
articulating the contours of its argument, SCIF appears to contend that because, in its
view, ReadyLink was required to raise the issue of the amount of premium with the
Insurance Commissioner under some theory of exhaustion of administrative remedies and
failed to do so, ReadyLink could have litigated that issue in the administrative
proceeding, such that either claim preclusion or issue preclusion should now bar it from
litigating its affirmative defenses to SCIF's contract action.
36
SCIF's complaint in this case includes a claim for breach of contract, a common
count for reasonable value, and a claim for "open book." The elements of a claim for
breach of contract are: (1) the existence of a contract; (2) the plaintiff's performance or
excuse for nonperformance of the contract; (3) defendant's breach; and (4) damage to
plaintiff resulting from the breach. (Oasis West Realty, LLC v. Goldman (2011) 51 Cal.
4th 811, 821.) A common count for reasonable value has the following elements:
(1) plaintiff performed certain services for the defendant; (2) the reasonable value of
those services; (3) the services were rendered at the request of the defendant; and (4) the
services were unpaid. (Haggerty v. Warner (1953) 115 Cal.App.2d 468, 475.) The
elements of an open book account cause of action are: "1. That [plaintiff] and
[defendant] had financial transactions . . . ; [¶] 2. That [plaintiff] . . . kept [an] account of
the debits and credits involved in the transactions; [¶] 3. That [defendant] owes [plaintiff]
money on the account; and [¶] 4. The amount of money that [defendant] owes [plaintiff]."
(CACI No. 372.) For every cause of action that SCIF has asserted, SCIF must establish
the amount of money due (in the form of damages, reasonable value of services, or
money due on an open book account).
ReadyLink's affirmative defenses to SCIF's complaint include estoppel,
ratification, fraud, unclean hands, waiver, and violation of Insurance Code section 381.21

21 Insurance Code section 381, subdivision (f) provides that an insurance policy shall
specify "[e]ither: [¶] (1) A statement of the premium, or [¶] (2) If the insurance is of a
character where the exact premium is only determinable upon the termination of the
contract, a statement of the basis and rates upon which the final premium is to be
determined and paid."
37
All of these affirmative defenses are based on ReadyLink's general factual allegations,
which include the following assertions: that ReadyLink "was upfront with SCIF about its
compensation structure and fully disclosed its per diem to SCIF" (italics omitted) when it
purchased insurance from SCIF; that "[a]fter reviewing ReadyLink's [per diem reliant]
compensation structure, and with full knowledge of that structure, SCIF represented to
ReadyLink what ReadyLink's premiums would be based upon ReadyLink's [per diem
reliant] compensation method"; that "[i]n deciding to purchase insurance from SCIF,
ReadyLink reasonably relied upon SCIF's representation that it had fully reviewed
ReadyLink's compensation formulas and that the premium SCIF was offering . . . was the
premium SCIF would charge"; that "SCIF repeatedly audited ReadyLink for the 2000
through 2004 calendar years and did not say a peep to ReadyLink about whether
ReadyLink's [per diem reliant] compensation formulas could lead to an additional
premium down the road"; that "ReadyLink believed, and had every reason to believe, that
SCIF had looked at ReadyLink's payroll practices and properly charge[d] premiums
based on those practices"; that "SCIF paid [workers' compensation] claims [out] to nurses
using the very salary schedules ReadyLink used[, which excluded per diem payments as
wages]"; and that if "ReadyLink [had] known the truth about SCIF's intentions [to later
contend ReadyLink did not properly classify all of its payroll as payroll], it would not
have done business with SCIF."
A review of the record, including the ALJ's Proposed Decision as adopted by the
Insurance Commissioner, clearly demonstrates that none of these factual allegations, nor
the legal impact of such allegations with respect to SCIF's breach of contract/collection
38
action, was at issue in the administrative proceeding, much less decided by the ALJ.
Further, although the trial court concluded that SCIF was entitled to judgment on the
pleadings because, as the trial court stated, "[t]he amount owed is precisely what was
determined in the underlying administrative decision and appeals," in fact, the ALJ's
Proposed Decision demonstrates that the ALJ did not consider or determine the amount
of premium that ReadyLink owes SCIF under the 2005 policy contract.
The single issue before the ALJ was whether SCIF's inclusion as payroll those
amounts that ReadyLink paid to its employee nurses as per diems for the 2005 policy
year complied with the USRP. Indeed, in a letter sent from the WCIRB to the ALJ
assigned to decide ReadyLink's appeal, the WCIRB asserts that "[t]he matter under
appeal is whether the monies that ReadyLink paid to its employees as 'subsistence
payments' should be included as payroll." The letter further states: "The WCIRB has no
first hand knowledge of the manner in which ReadyLink either compensates its
employees or reimburses them for travel expenses. That said, pursuant to the above
referenced section of Appendix III [of USRP, the Payroll Remuneration Table], should it
be determined that the payments . . . should be excluded from payroll. [¶] If it is
determined that the payments in question cannot reasonably be considered to be
payments to cover an employee's additional expenses incurred based upon a job's
location, then all or a portion of the monies should be included as payroll."
The ALJ defined the issue to be decided as whether SCIF had properly interpreted
and applied the Insurance Commissioner's regulations for determining payroll to include
ReadyLink's per diem payments to its employees; the ALJ did not define the issue to be
39
decided as whether the premium amount that SCIF had calculated as being due by
ReadyLink was accurate. The ALJ introduced the matter by stating that the appeal was
about a dispute "regarding the proper calculation of payroll for premium and statistical
reporting purposes under the terms of the California Workers' Compensation Uniform
Statistical Reporting Plan." (Italics added.) The ALJ identified the "Statement of Issues"
as including a single issue: "1. For policy year 2005, did SCIF properly include per diem
payments made to registry nurses as 'payroll' or 'remuneration' pursuant to USRP, Part 3,
Section V?"
In determining this issue, the ALJ considered evidence regarding ReadyLink's per
diem program, as well as evidence of the per diem programs of other nurse staffing
companies and evidence provided by SCIF regarding its audit procedure. In her decision,
the ALJ provided background regarding the relevant regulatory framework, including
information regarding the WCIRB's function—i.e., "to collect accurate payroll and loss
information regarding every California workers' compensation insurance policy." The
ALJ noted that "[g]iven the critical nature of accurate data, every insurer must record and
report its policy payroll and claims loss data to the WCIRB pursuant to the rules in the
USRP." (Italics added.) Thus, as the ALJ viewed it, her task was to determine whether
SCIF, as a workers' compensation insurer, was accurately reporting to the WCIRB the
payroll amounts under its issued policies pursuant to the regulations governing how
payroll is to be determined.
As the ALJ noted, the USRP excludes from payroll "[s]ubsistence payments" that
"are considered to be reimbursements for the additional living expense[s] by virtue of job
40
location," and further allows that such excluded "[s]ubsistence payments" may be
"stipulated per diem amounts" if " 'the amount is reasonable and the employer's records
show that the employee worked at a job location that would have required the employee
to incur additional expenses not normally assumed by the employee.' " The ALJ
explained that the USRP did not define " 'reasonable,' " nor did it provide guidelines as to
what might constitute " 'additional expenses not normally assumed by the employee.' "
Thus, the ALJ set out to interpret the word " 'reasonable' " in the USRP's reference to
stipulated per diem amounts, and also to interpret the meaning of the USRP's reference to
records demonstrating that the employee was " 'working at a location that would have
required an employee to incur additional expenses not normally assumed.' " After
providing interpretations of those portions of the USRP, the ALJ proceeded to apply
those standards to the facts presented regarding ReadyLink's per diem payment program.
The ALJ concluded that ReadyLink's stipulated per diem amount was not "reasonable"
under the USRP, and that ReadyLink had failed to demonstrate that its nurses who
received the per diem payments had been working in a location where they would have
incurred additional living expenses that they would not have otherwise normally
assumed. As a result, the ALJ concluded that ReadyLink had not met its burden to
demonstrate that SCIF had improperly included the per diem amounts paid to
ReadyLink's nurse employees in calculating ReadyLink's 2005 policy year premium, and
further concluded that it was therefore appropriate to affirm "SCIF's decision regarding
the 2005 policy year audit."
41
It is clear from the entirety of the ALJ's written decision that the ALJ's seemingly
broad statement—i.e., that "SCIF's decision regarding the 2005 policy year audit" was
affirmed—would be more accurately stated as "SCIF's decision [to include as payroll
those amounts that ReadyLink paid to its nurses as stipulated per diem payments]
regarding the 2005 policy year audit" was affirmed. This is because, as noted, the sole
issue that the ALJ determined in her Proposed Decision (and thus the sole issue
determined by the Insurance Commissioner) was whether SCIF had correctly interpreted
and applied the USRP standards regarding the inclusion of ReadyLink's per diem
payment as payroll for use in calculating ReadyLink's premium.22 Further, a review of

22 At no point in the Proposed Decision did the ALJ make any comment about
SCIF's calculation of the dollar amount of ReadyLink's premium, nor did she purport to
suggest that the amount of premium that SCIF was claiming ReadyLink owed pursuant to
the audit was in fact owed by ReadyLink. The ALJ made no comment regarding the
validity of the insurance contract, the premium calculated pursuant to that contract, or the
facts on which ReadyLink relies in asserting its affirmative defenses to SCIF's collection
action. Indeed, the ALJ did not discuss any issues regarding the precontract conduct of
ReadyLink or SCIF, or possible representations made by SCIF to ReadyLink prior to
ReadyLink's decision to purchase insurance from SCIF.
42
the subsequent proceedings initiated by ReadyLink to challenge the Insurance
Commissioner's decision to adopt the ALJ's Proposed Decision also demonstrates that the
parties were not litigating either the amount of premium owed or the broad range of
issues that arise from the complaint in this collection action and the affirmative defenses
to the collection action asserted in the first amended answer.
In its ruling on ReadyLink's petition for a writ of administrative mandamus, the
trial court summarized the "dispute between [SCIF] and ReadyLink" as a dispute
"regarding the proper determination of Petitioner's total nurse payroll paid out during its
2005 policy period," which the court thereafter described as a question involving the
interpretation of the USRP.23 Absent from this description is any suggestion that the

At the administrative hearing, the ALJ specifically told the parties that she was not
considering whether the final premium calculated by SCIF had been calculated correctly.
At the hearing, counsel for ReadyLink expressed the following concern regarding exactly
what occurred in this litigation: "My concern, quite frankly, is I don't want a court
ultimately to say that I'm precluded from challenging [SCIF's] entitlement to an amount
of premium independent of whether a certain amount of payroll is reportable for USRP.
[¶] I do understand there's a relationship between the amount of payroll and the USRP
and the amount of premium [finally calculated]. Ultimately, it [i.e., the final premium
due and payable] depends on a lot of other factors too, re filings and conduct." In
response the ALJ stated, "Right. And what I'm doing is ruling on the USRP and whether
SCIF applied it accurately in this case. [¶] Ultimately, where [sic] you end up paying
SCIF or any compromises made down the line, if I call it [i.e., the per diem amounts]
payroll, is not something I get to rule on. And I don't get to say what the premium should
be, either, because I don't actually know how it's calculated . . . necessarily." (Italics
added.)
23 The trial court noted that "Insurance Code § 11737, provides a reasonable means
by which any person may challenge the rating system that has been applied to them in
connection with the insurance provided. And, a party may appeal to the Commissioner,
who may hold a hearing to determine whether an existing rating plan has been correctly
applied to an employer. [Fn. omitted.] Insurance Code § 11737, subd. (f)."
43
dispute involved other questions, such as the total amount of the premium owed by
ReadyLink, or whether SCIF's past conduct in relation to ReadyLink might provide a
legal basis for ReadyLink to avoid having to pay the premium for the 2005 policy year as
determined by SCIF.
However, the trial court's ruling does demonstrate that certain other issues related
to the propriety of including per diem payments in payroll were also "actually litigated"
and "decided" (DKN Holdings, supra, 61 Cal.4th at p. 825) in the writ proceeding.
Specifically, ReadyLink argued in favor of the issuance of a writ of administrative
mandamus on four grounds, all addressed by the trial court in that proceeding: (1) that
the Insurance Commissioner's application of the USRP to ReadyLink's per diem payment
structure constituted a "[n]ew [r]egulation," and that the Insurance Commissioner had no
authority to issue a new regulation; (2) that the Insurance Commissioner's interpretation
of the USRP and his application of that interpretation to the facts of ReadyLink's per
diem payment structure was impermissibly retroactive; (3) that the Insurance
Commissioner was bound by the results of an IRS tax audit and/or was required to adopt
IRS standards or rules in order to interpret the USRP's rules regarding payroll; and
(4) that the Insurance Commissioner improperly exceeded his authority by addressing a
"rate controversy" regarding the rates in State Fund rate filing. The trial court rejected all
of ReadyLink's contentions and denied its petition for a writ of administrative mandamus.
None of these issues involves a determination as to the final amount of premium that
ReadyLink owes (after a determination of all of the relevant inputs and the appropriate
44
application of relevant calculations), or whether ReadyLink has any defenses to SCIF's
collection action based on SCIF's conduct prior to the 2005 policy year.
The trial court's determination of these issues became final upon the affirmance of
its judgment by the appellate court in ReadyLink Healthcare, supra, 210 Cal.App.4th at
p. 1172, with review denied in the Supreme Court on February 13, 2013, and once the
time for filing a petition for writ of certiorari to the United States Supreme Court passed.
(See People v. Buycks (2018) 5 Cal.5th 857, 876 ["A judgment becomes final when the
availability of an appeal and the time for filing a petition for certiorari with the United
States Supreme Court have expired. [Citation.]"].)
A review of ReadyLink Healthcare, supra, 210 Cal.App.4th 1166, further
demonstrates that the issues that remain to be decided in this collection action were not
previously considered, let alone decided, in the appellate review from the writ
proceeding. The appellate court in ReadyLink Healthcare addressed ReadyLink's four
claims of error: (1) whether the trial court applied the correct standard of review in
assessing ReadyLink's petition for a writ of administrative mandamus (id. at p. 1172);
(2) whether the Insurance Commissioner's decision was preempted by federal law (id. at
p. 1173); (3) whether the Insurance Commissioner's decision constituted a "new
regulation" that required a public hearing and opportunity to comment under Insurance
Code section 11750, subdivision (b) (ReadyLink Healthcare, supra, at pp. 1177–1178);
and (4) whether equitable considerations, including arguments that the Insurance
Commissioner's decision constituted a new regulation, that "ReadyLink's recordkeeping
practices were based on the advice of payroll and legal experts and passed muster with
45
the IRS," and that "SCIF's prior audits had excluded the same per diem payments from
ReadyLink's payroll," required that the administrative decision not be applied to include
the per diem payments as payroll for purposes of determining ReadyLink's premium for
the 2005 policy year (id. at p. 1179).24 None of these issues involves the question of the
"amount" of premium "owed." Nor do these issues address the factual questions raised
by ReadyLink's first amended answer, such as whether SCIF knew about ReadyLink's per
diem payment structure before ReadyLink purchased insurance through SCIF, whether
SCIF affirmatively represented to ReadyLink that its premiums would be calculated
based on that per diem payment structure, or whether ReadyLink reasonably relied on
such representations, if they occurred, in purchasing insurance through SCIF. Neither the
Insurance Commissioner, the trial court nor the appellate court addressed whether, if the

24 Although at least one of the "equitable considerations" raised by ReadyLink before
the appellate court in ReadyLink Healthcare, supra, 210 Cal.App.4th 1166, sounds
similar to the estoppel defense that ReadyLink argues it should be permitted to pursue in
this contract action, the two issues are not identical. ReadyLink argued in ReadyLink
Healthcare that the appellate court should reverse the trial court's denial of ReadyLink's
petition for a writ of mandate in part on the ground that the ALJ should have interpreted
the USRP rules differently, and should have determined that the USRP did not require the
inclusion of ReadyLink's per diem payments as payroll because, among other things,
SCIF had not included those per diem payments as payroll in calculating prior year
payroll amounts. The appellate court in ReadyLink Healthcare rejected the idea that the
Insurance Commissioner should have altered his interpretation of the USRP rules based
on SCIF's prior conduct in applying those rules. However, this was not a determination
that SCIF's prior conduct cannot form the basis of an equitable estoppel defense in
response to a breach of contract claim. We do not make this distinction to suggest that
ReadyLink will ultimately prevail on its equitable estoppel argument, but, rather, merely
to explain that the equitable estoppel issue that ReadyLink seeks to raise in this case has
not previously been litigated.
46
facts alleged by ReadyLink are true, they amount to fraud or waiver such that SCIF
should be precluded from collecting a premium based on calculations that include the per
diem payments as payroll.25
Further, none of ReadyLink's affirmative defenses to SCIF's collection action were
relevant to the issues addressed by the Insurance Commissioner, the trial court or the
appellate court, nor were they considered or decided in the collateral federal proceedings
initiated by ReadyLink to challenge the Insurance Commissioner's adoption of the ALJ's
decision. As we have already described, ReadyLink's putative class action lawsuit filed
against SCIF and the Insurance Commissioner in the federal district court alleged that
IRS regulations pertaining to per diem payments preempted the Insurance
Commissioner's decision regarding the treatment of ReadyLink's per diem payments for
purposes of calculating payroll for workers' compensation insurance under the USRP.
(See ReadyLink Healthcare, Inc. v. State Compensation Ins. Fund, supra, 754 F.3d at p.
757.) The federal district court decided two issues in dismissing the case: (1) that the

25 For purposes of resolving a motion for judgment on the pleadings, a court must
" 'assum[e] the truth of all material facts properly pled.' " (Angelucci, supra, 41 Cal.4th at
p. 166.) For this reason, we must assume the truth of the facts alleged in ReadyLink's
first amended answer, and, assuming their truth, consider their potential legal import.
However, it is important to note that we do not intend to imply that ReadyLink will or
will not prevail on any of its affirmative defenses. Rather, we conclude only that
ReadyLink should have the opportunity to litigate the issues that it raises in defense of
SCIF's collection action based on the allegations in its first amended answer, since these
issues have not been the subject of prior litigation between the parties, and, as we discuss
further in section III.B.3.b, post, ReadyLink could not properly have raised these issues in
the prior administrative proceedings.
47
Younger requirements for abstention were met with respect to ReadyLink's request for
declaratory and injunctive relief on federal preemption grounds, and (2) that it would
decline to exercise supplemental jurisdiction over any remaining state-law claims.
(ReadyLink Healthcare, Inc. v. State Compensation Ins. Fund, supra, at p. 757.) Thus,
the federal district court decided issues related solely to the propriety of a federal court
deciding any of the issues raised in the complaint on their merits. Upon ReadyLink's
appeal, the Ninth Circuit Court of Appeals also considered only two issues, albeit one
issue considered by the trial court, and a second issue not considered by the trial court:
(1) whether the Younger abstention doctrine provided grounds for the trial court to
decline to adjudicate ReadyLink's claim for declaratory and injunctive relief based on
federal preemption, and (2) whether principles of issue preclusion arising from the state
appellate court's rejection of the federal preemption argument barred ReadyLink from
relitigating the federal preemption argument. (ReadyLink Healthcare, Inc. v. State
Compensation Ins. Fund, at pp. 757–760, 760–762.) It is readily apparent that none of
the issues addressed in the federal action, either at the district court or appellate court
level, concerns the amount of premium owed by ReadyLink.
The trial and appellate courts in the federal action did not consider, much less
decide, the question of the amount of premium actually owed by ReadyLink for workers
compensation insurance for the 2005 policy year. However, in considering the issues
raised on SCIF's motion for judgment on the pleadings, the trial court appears to have
given undue weight to a single sentence in the Ninth Circuit Court of Appeals' opinion.
Specifically, in a section providing background context regarding the collateral
48
administrative and court proceedings that ReadyLink had initiated in California forums,
the Ninth Circuit described what it understood to have taken place in the administrative
proceeding, summarizing that proceeding as follows:
"When SCIF audited ReadyLink for the 2005 policy year, it found
that ReadyLink had failed to report certain per diem payments to
employees as payroll, and billed ReadyLink for an additional
premium of $555,327.53. ReadyLink appealed that decision to the
California Department of Insurance, see Cal. Ins. Code § 11737(f),
and an administrative law judge (ALJ) approved SCIF's premium
calculation." (ReadyLink Healthcare, Inc. v. State Compensation
Ins. Fund, supra,754 F.3d at p. 757.)
The trial court in this case seized on the Ninth Circuit's description of what the
Ninth Circuit understood the ALJ to have done (i.e., "an administrative law judge (ALJ)
approved SCIF's premium calculation") and appears to have concluded that the Ninth
Circuit's descriptive statement regarding what it believed had occurred in the
administrative proceeding should itself be given preclusive effect. In other words, the
trial court appears to have concluded that the Ninth Circuit's statement that "an
administrative law judge (ALJ) approved SCIF's premium calculation" was a
determination, on the merits that the ALJ had determined, on the merits, that ReadyLink
owed SCIF the additional premium amount that SCIF had charged ReadyLink.26 The

26 During arguments on SCIF's motion for judgment on the pleadings, the trial court
made several comments that indicate that the court was laboring under the misconception
that the issue of the amount of the premium had been "determined" by the Ninth Circuit
when it described what the ALJ had done, including:
• "Didn't the United States Court of Appeal confirm an issue
that was litigated and/or, to use your words, could have been
litigated regarding the premium calculation? And the Court
said, quote, 'And an administrative law judge approved
49
trial court thus relied on two levels of issue preclusion to bar ReadyLink from litigating
its affirmative defenses to SCIF's contract action. However, the question of what issues
had been considered and decided by the ALJ, or what other issues could have been raised
but were not, in the administrative proceeding was not before the Ninth Circuit; rather,
the Ninth Circuit was merely attempting to summarize what had occurred in prior

SCIF's premium calculation.' That can only be fairly
interpreted to mean that the administrative law judge, at least
so far as the U.S. Court of Appeal for the Ninth Circuit[ ]
determined was a premium calculation and amount."
• "Going back to the U.S. Court of Appeals for the Ninth
Circuit in which the U.S. Court of Appeals determined that
the administrative law judge had, in fact, approved SCIF's
premium calculation, my question to you, sir, is have you --
in any of your appeals, did you every attack the number for --
no, strike that -- did you ever attack either the amount of the
premium or the manner in which the premium was
calculated? And, if so, wasn't that determined adverse to you
when the court determined that the administrative law judge
approved SCIF's premium calculation?" (Italics added.)
• "My next question to you is when you received the opinion
from the U.S. Court of Appeals in which that opinion states,
quote, 'And an administrative law judge approved SCIF's
premium calculation,' did you seek any further appellate
review of that finding?" (Italics added.)
• "Why doesn't that then dispose of the issue as to that
finding -- [¶] . . . [¶] . . . -- on a res judicata and collateral
estoppel analysis?" (Italics added.)
These questions by the trial court demonstrate that the court appears to have
believed that the Ninth Circuit had made a "finding" of fact or had "determined" that the
issue of the amount of premium due had previously been determined, such that the Ninth
Circuit's opinion had some sort of preclusive effect with respect to the amount of
premium due. However, SCIF's attorney actually noted during these oral arguments that
the issue of the amount of premium due from ReadyLink "didn't get adjudicated because
it wasn't submitted by ReadyLink."
50
litigation between the parties. A loose description of the history of a collateral
proceeding cannot form the basis of a preclusive determination of an issue on its merits.
(See Hernandez, supra, 46 Cal.4th at p. 511 ["For purposes of [issue preclusion], an issue
was actually litigated in a prior proceeding if it was properly raised, submitted for
determination, and determined in that proceeding" (italics added)].) Here, the issue of
the dollar amount of the premium was not decided by the ALJ; the Ninth Circuit's
statement in ReadyLink Healthcare, Inc. v. State Compensation Ins. Fund regarding what
it believed the ALJ had decided was provided merely as background.
Our review of the collateral proceedings between ReadyLink and SCIF makes
clear that the trial court erred in concluding that the issues raised by SCIF's collection
action and by ReadyLink's affirmative defenses to that action had been litigated and
decided in a prior action.
b. Contrary to SCIF's assertions, ReadyLink could not have raised as
"claims" in the prior administrative proceeding those matters that
form its affirmative defenses in this action
The trial court granted SCIF's motion for judgment on the pleadings based on the
erroneous conclusion that "[t]he amount [of premium] owed [by ReadyLink] is precisely
what was determined in the underlying administrative decision and appeals." SCIF
contends that if these issues were not in fact previously determined in the underlying
administrative proceeding, it is because "ReadyLink disregarded its opportunity to
dispute the premium owed before the Insurance Commissioner" (boldface & some
capitalization omitted). SCIF thus suggests that ReadyLink should be barred from
litigating its affirmative defenses in response to SCIF's breach of contract action against it
51
on the basis that ReadyLink could have, and should have, litigated before the ALJ the
issue of the amount of premium due. SCIF asserts that ReadyLink "was required to
exhaust its administrative remedies, which included the opportunity to dispute the
premium owed, before the Department of Insurance, when it brought its initial appeal,"
but ReadyLink "affirmatively chose not to do so."
SCIF is incorrect in suggesting that ReadyLink should be barred from litigating
the amount of premium due (apart from that aspect of the premium that involves
including the per diem payments as payroll for premium calculation purposes, which has
been litigated and decided), or whether SCIF is not entitled to full payment of the
premium claimed, as alleged in ReadyLink's affirmative defenses. SCIF appears to be
suggesting that the prior administrative action has preclusive effect as to all other issues
raised by ReadyLink in this case because, SCIF maintains, ReadyLink was required to
exhaust its administrative remedies by raising the other issues in the administrative
proceeding before the Insurance Commissioner, and its failure to do so precludes it from
raising these issues now. Although causes of action or defenses that could have been
brought in an earlier action may be barred because they are subject to claim preclusion,
"a prior judgment generally does not bar a subsequent claim if the matter could not have
been raised or litigated in the earlier action." (Hong Sang, supra, 20 Cal.App.5th at p.
491, italics omitted.) Despite SCIF's suggestions to the contrary, SCIF has presented no
authority to demonstrate that ReadyLink could have actually litigated the issues bearing
on whether SCIF calculated the correct premium amount, or issues regarding its
affirmative defenses in the administrative proceeding.
52
"Administrative agencies have only such powers as have been conferred on them,
expressly or by implication, by Constitution or statute." (Noble v. Draper (2008) 160
Cal.App.4th 1, 12.) The record in this case reveals Insurance Code sections 11753.1 and
11737, subdivision (f) as possible statutory bases for ReadyLink's appeal to the Insurance
Commissioner of SCIF's audit decision to include the per diem payments as payroll.
Both of these statutory provisions make clear that only the matters identified in those
statutory provisions may be appealed to, and determined by, the Insurance
Commissioner.27 Neither of these provisions indicates that the Insurance Commissioner

27 Insurance Code section 11753.1 provides that the Insurance Commissioner has the
authority to consider appeals from a "decision, action, or omission of the rating
organization," or from "the reclassification pursuant to this section [i.e., a change in the
classification assignment that results in an increased premium]." That statute provides:
"(a) Any person aggrieved by any decision, action, or omission to
act of a rating organization may request that the rating organization
reconsider the decision, action, or omission. If the request for
reconsideration is rejected or is not acted upon within 30 days by the
rating organization, the person requesting reconsideration may,
within a reasonable time, appeal from the decision, action, or
omission of the rating organization. The appeal shall be made to the
commissioner by filing a written complaint and request for a hearing
specifying the grounds relied upon. If the commissioner has
information on the subject appealed from and believes that probable
cause for the appeal does not exist or that the appeal is not made in
good faith, the commissioner may deny the appeal without a hearing.
The commissioner shall otherwise hold a hearing to consider and
determine the matter presented by the appeal.
"(b) Any insurer adopting a change in the classification assignment
of an employer that results in an increased premium shall notify the
employer in writing, or if the insurance was transacted through an
insurance agent or broker, the insurer shall notify the agent or broker
who shall notify the employer in writing of the change and the
reasons for the change. Any employer receiving this notice shall
53
has the authority to consider the common law breach of contract and other collection
claims raised by SCIF in this action, or to consider the equitable and other affirmative
defenses to SCIF's claims asserted by ReadyLink. We have been directed to no authority
that would suggest that the Insurance Commissioner has any authority to consider other
aspects of a premium calculation dispute, beyond the specific matters identified in

have the right to request reconsideration and appeal the
reclassification pursuant to this section. The notice required by this
section shall inform the employer of his or her rights pursuant to this
section. No notification shall be required when the change is a result
of a regulation adopted by the Department of Insurance or other
action by or under the authority of the commissioner."
Insurance Code section 11737, subdivision (f) authorizes an appeal to the
Insurance Commissioner to allow the Commissioner to "review the manner in which [a]
rating system has been applied in connection with the insurance afforded or offered" to
the insured. That statute provides:
"(f) Every insurer or rating organization shall provide within this
state reasonable means whereby any person aggrieved by the
application of its filings may be heard by the insurer or rating
organization on written request to review the manner in which the
rating system has been applied in connection with the insurance
afforded or offered. If the insurer or rating organization fails to
grant or reject the request within 30 days, the applicant may proceed
in the same manner as if the application had been rejected. Any
party affected by the action of the insurer or rating organization on
the request may appeal, within 30 days after written notice of the
action, to the commissioner who, after a hearing held within 60 days
from the date on which the party requests the appeal, or longer upon
agreement of the parties and not less than 10 days' written notice to
the appellant and to the insurer or rating organization, may affirm,
modify, or reverse that action. If the commissioner has information
on the subject from which the appeal is taken and believes that a
reasonable basis for the appeal does not exist or that the appeal is not
made in good faith, the commissioner may deny the appeal without a
hearing. The denial shall be in writing, set forth the basis for the
denial, and be served on all parties."
54
sections 11753.1 and 11737, subdivision (f). In fact, case law and the records in this case
suggest otherwise.
For example, courts have rejected the idea that an insured must first exhaust
administrative remedies through an appeal to the Insurance Commissioner before
asserting claims of breach of contract against its insurer, including breaches that place the
amount of premium in dispute. (See Lance Camper Manufacturing Corp. v. Republic
Indemnity Co. (1996) 44 Cal.App.4th 194, 199 (Lance Camper); Tricor California, Inc.
v. State Compensation Ins. Fund (1994) 30 Cal.App.4th 230; Security Officers Service,
Inc. v. State Compensation Ins. Fund (1993) 17 Cal.App.4th 887.) "The requirement of
exhaustion of administrative remedies is founded on the theory that the administrative
tribunal is created by law to adjudicate the issue sought to be presented to the court, and
the issue is within its special jurisdiction. If a court allows a suit to go forward prior to a
final administrative determination, it will be interfering with the subject matter of another
tribunal. . . . [¶] [However,] [t]he mere possession by some official body of a continuing
supervisory or investigatory power does not itself suffice to afford an administrative
remedy unless the statute or regulation under which that power is exercised establishes
clearly defined machinery for the submission, evaluation and resolution of complaints by
aggrieved parties." (Horsemen's Benevolent & Protective Assn. v. Valley Racing Assn.
(1992) 4 Cal.App.4th 1538, 1552–1553.) In the workers' compensation insurance arena,
"[t]he [Insurance] Commissioner's supervisory and regulatory power over the insurance
industry does not give him power to adjudicate all insurance disputes—such as . . . one
[that] involves an alleged breach of contract with a demand for monetary damages—
55
unless persuasive legislative intent to grant this authority can be identified." (Lance
Camper, supra, at p. 199.) The Lance Camper court found no persuasive legislative
intent to grant authority to the Insurance Commissioner to consider an insured's causes of
action challenging the conduct of the insurer with respect to the insurance contract
between them, including a challenge that the amount of the premium was too high as a
result of the insurer's wrongful conduct. The Lance Camper court thus determined that
the insured's claims were "not . . . subject to administrative review." (Id. at p. 203.)
Further, the Insurance Commissioner has concluded that he does not have
authority to consider breach of contract issues between insurers and insureds. In In the
Matter of the Appeal of SportsMobile West, Inc. (2007) file No. AHB -WCA-06-7
(available at ), the Insurance Commissioner specifically
stated that "SCIF correctly argues that the Commissioner does not have jurisdiction to
56
decide the rights and duties of parties to a contract." (Id. at p. 4, fn. 10.)28 A number of
documents in the record in this case further demonstrate not only that the Insurance
Commissioner did not view himself as having the authority to determine a contract
dispute between the parties, but that the Insurance Commissioner expressed to the parties
that his jurisdiction was indeed limited. For example, when ReadyLink initially appealed

28 SCIF suggests that other precedential decisions of the Insurance Commissioner
demonstrate that the Insurance Commissioner does decide matters regarding the amount
of premiums due under insurance contracts. SCIF relies on In the Matter of the Appeal of
Advanced Fuel Filtration Systems (2004) file No. AHB-WCA-03-45 (Advanced Fuel)
and In the Matter of the Appeal of E. M. Machining (2001) file No. ALB-WCA-00-30
(E. M. Machining), of which we have granted judicial notice, to suggest that the
"Commissioner deliberates and decides premium issues when they are raised before it."
These authorities do not support SCIF's position. Advanced Fuel involved the "sole
issue" described as follows: "Whether SCIF's retroactive assignment of classification
codes 8018 (stores - wholesale), 7219 (truckmen), 6218/6220 (excavation) and 4511
(analytical or testing laboratories) to AFFS's policies is contrary to Insurance Code
sections 11753.l(b) and 11753.2." (Advanced Fuel, supra, at p. 2, Proposed Decision of
ALJ.) Thus, as in this case, the Insurance Commissioner was considering whether SCIF
had properly applied relevant statutory and regulatory rules in conducting its audit. The
Insurance Commissioner, through an ALJ, made a determination that SCIF had properly
applied the classification codes in question, and acknowledged that the decision would
result in an increase in premiums for the insured. The ALJ did not, however, decide the
contractual issue of what final premium amount was due, or whether the employer would
have any valid defenses to a breach of contract action. Similarly, E. M. Machining
involved "the question whether the WCIRB properly assigned classification 3643 (1),
'Electric Power or Transmission Equipment Mfg.–N.O.C.' to EMM's operations by
analogy, pursuant to the Standard Classification System, Part 3, of the California
Workers' Compensation Uniform Statistical Reporting Plan ('Plan')." (E. M. Machining,
supra, at p. 2.) Again, the Insurance Commissioner, through an ALJ, considered whether
the relevant regulatory framework was being applied correctly. These cases do not
demonstrate what SCIF appears to suggest by implication— i.e., that the Insurance
Commissioner may decide any premium issue raised before it, including whether the
premium accurately reflects the contract between the parties, based on issues unrelated to
the application of the relevant statutory and regulatory rules.
57
to the Insurance Commissioner regarding SCIF's application of the USRP rules to
determine ReadyLink's payroll for the 2005 policy year, the Department of Insurance sent
ReadyLink a letter, dated April 29, 2008, in which an employee of the Department of
Insurance informed ReadyLink's representative that "[t]he Insurance Commissioner is
authorized by the California Insurance Code to investigate allegations of unlawful
activities by licensees. The Department will initiate an investigation into your complaint
against the licensee to determine whether the licensee has violated the California
Insurance Code. The Department's regulatory activities will be separate from, and will
not include, the mediation or negotiation of your complaint. However, if the Department
determines from its investigation that your dispute resulted from the licensee's failure to
comply with the code, the Department can request that the licensee take corrective action
to achieve compliance." (Italics added.)
Later, in the letter sent from the WCIRB to the ALJ assigned to ReadyLink's
appeal, the WCIRB states:
"A review of the record indicates that the appellant, ReadyLink
Healthcare, Inc. (ReadyLink) is appealing the State Compensation
Insurance Fund's (State Fund)[ ] audit of Policy no. 1596579,
effective for the period September 1, 2005 to September 1, 2006.
ReadyLink is appealing the State Fund's determination that the
monies ReadyLink paid to its employees as 'per diem' should be
included as payroll for premium computation purposes. ReadyLink
argues that the payments in question are 'government per-diem
amounts' and that because ReadyLink 'does not set them, modify
them, negotiate them, nor vary them among nurses,' the monies meet
the criteria for a reasonable 'stipulated amount,' and therefore should
not be included as payroll.
"In its February 28, 2008 letter, the State Fund argues that 'the
amounts listed as per diem have not yet been shown to be
58
reasonable' and therefore must be included as payroll for premium
computation purposes. Indeed, the State Fund states that 'proposing
that a vast majority of the nurses' payroll is for unverified travel
expenses, is not reasonable and can not [sic] be accepted."
"Preliminarily, it should be noted that the WCIRB's jurisdiction in
this matter is limited to ensuring that the required Unit Statistical
Report [USRP] both accurately reflects the policy's payroll and loss
experience, as well as reports all such experience under the
appropriate standard classification. However, the WCIRB does not
have the authority to make determinations in matters concerning
[the] basis of premium disputes between insurers and policyholders.
At most, the WCIRB would be able to provide expertise with respect
to the California Workers' Compensation Uniform Statistical
Reporting Plan's [i.e., the USRP's] provisions regarding the basis of
premium for workers' compensation purposes." (Italics added;
underscoring added to demonstrate italics in original.)
Further, the ALJ in this case specifically informed the parties that she was not
determining, and in fact could not determine, whether the ultimate premium charged by
SCIF was correct. The ALJ specifically stated, "I don't get to say what the premium
should be . . . because I don't actually know how it's calculated . . . ." The ALJ also
expressed her inability "to rule on" whether ReadyLink would have to pay the premium
determined by SCIF, or whether there might be "compromises made down the line." The
ALJ clearly did not view her role as determining the accuracy of SCIF's final premium
calculation.
Despite all of this, SCIF argues on appeal that ReadyLink was required to exhaust
its administrative remedies by asking Insurance Commissioner to determine the
correctness of SCIF's calculation of the premium amount and the validity of ReadyLink's
affirmative defenses, and that its failure to do so bars it from litigating those issues now.
The authority on which SCIF relies in claiming that ReadyLink failed to exhaust its
59
administrative remedies does not support SCIF's assertion. SCIF relies on
P. W. Stephens, Inc. v. State Compensation Ins. Fund (1994) 21 Cal.App.4th 1833
(P. W. Stephens), for the proposition that "a policyholder seeking relief from excessive
surcharges must first exhaust administrative remedies before resorting to the courts."
However, P. W. Stephens is inapposite. The narrow questions before the court in
P. W. Stephens were whether the SCIF was permitted, by statute or regulation, to impose
a surcharge on its premiums, and whether arbitrary, exorbitant, discriminatory or unfair
surcharges were subject to administrative review. Notably, the Legislature has
"specifically required that workers' compensation insurers, including SCIF, not impose
any 'surcharges' or maintain reserves that are 'unfairly discriminatory' " through Insurance
Code section 11737.5. (P. W. Stephens, at p. 1839.) The P. W. Stephens court thus
concluded that the Legislature had entrusted the Insurance Commissioner to ensure that
any surcharges imposed by insurers "are fair and reasonable." (Id. at p. 1840.)
The dispute in P. W. Stephens involved what amounted to a rate-setting dispute,
for which administrative exhaustion was a prerequisite to resort to the courts. (See State
Compensation Ins. Fund v. Brown (1995) 32 Cal.App.4th 188, 199 [distinguishing
dispute at issue in P. W. Stephens from contractual dispute initiated by SCIF in which it
sought additional premiums from an employer based on SCIF's decision to include
independent contractors as employees for purposes of calculating premium].) "There is
good reason for deferring to an initial agency determination: the propriety of premium
rates and surcharges involve factors and methodology which require quasi-legislative
action involving expertise in the subject matter, and courts have traditionally given
60
deference to such agency determinations [citation]." (Ibid.) Indeed, the P. W. Stephens
court specifically relied on the fact that the Insurance Commissioner's expertise was
needed in the area of rate and surcharge setting, areas that are specifically designated by
statute as requiring the approval of the Insurance Commissioner, as well as the Insurance
Commissioner's creation of a mechanism by which a surcharge could be reviewed, in
concluding that administrative exhaustion was required with respect to the dispute at
issue there. "Such administrative review is appropriate because of the expertise of the
Commissioner and his agency resources and because of the complexity of the matter
presented. A determination of whether or not an overall premium, or a surcharge
component of a premium, is unfair and discriminatory [as was specifically prohibited
under a then-newly-enacted Insurance Code provision] requires a comprehensive
understanding of the manner in which the merit rating system schedules are generally
applied in the workers' compensation insurance business. Additionally, a reviewing body
requires familiarity with the manner in which surcharges are generally applied, and
familiarity with the particular occupations or businesses of the insureds in question. Such
expertise clearly resides with the Rating Bureau and with the office of the Commissioner
and certainly not initially with our trial courts." (P. W. Stephens, supra, 21 Cal.App.4th
at p. 1842.) In contrast, issues of contract interpretation, including whether an insurer
accurately calculated a premium under the contract, and the application of equitable
defenses to the enforcement of a contract, do not involve considerations that fall uniquely
within the Insurance Commissioner's expertise. P. W. Stephens thus does not support the
61
conclusion that ReadyLink was required to exhaust administrative remedies before
litigating the issues that arise from this contract dispute.
We therefore reject SCIF's suggestion that we may affirm the trial court's ruling on
SCIF's motion for judgment on the pleadings on the ground that, to the extent that we
have concluded that the issue of the amount of premium due or issues regarding the
validity of ReadyLink's affirmative defenses were not in fact determined in the prior
administrative proceeding, those issues could have been determined if ReadyLink had
properly raised them, and the prior administrative proceeding should therefore act as a
bar to ReadyLink raising them in this case under a theory of claim preclusion (see
Guerrero v. Department of Corrections & Rehabilitation (2018) 28 Cal.App.5th 1091,
1098 [principles of res judicata may be used to bar a party from asserting claims that
"could have been litigated" in a prior proceeding]). The administrative proceeding
involved the question whether SCIF had properly interpreted and applied the USRP rules
regarding payroll. The question whether SCIF properly applied the USRP rules in
including ReadyLink's per diem payments as payroll was well within the Insurance
Commissioner's expertise and jurisdiction. Although the answer to that question affected
the calculation of the ultimate premium due under the contract between SCIF and
ReadyLink, there is no basis to conclude that other matters going to the accuracy of
SCIF's premium calculations under the contract—matters not related to issues that
involve application of the regulatory rules or rate filings and are therefore within the
Insurance Commissioner's adjudicatory jurisdiction—or matters related to whether SCIF
62
can succeed on its contract claim could have been, raised with the Insurance
Commissioner.
C. The trial court's denial of ReadyLink's discovery motions was based on an
erroneous conclusion regarding the preclusive effect of the prior proceedings
ReadyLink challenges the trial court's order denying its motions to compel
discovery from SCIF. We review a trial court's ruling on a motion to compel discovery
for abuse of discretion. (Costco Wholesale Corp. v. Superior Court (2009) 47 Cal.4th
725, 733.) However, " ' "[t]he scope of [a court's] discretion always resides in the
particular law being applied, i.e., in the 'legal principles governing the subject of [the]
action . . . .' Action that transgresses the confines of the applicable principles of law is
outside the scope of discretion and we call such action an 'abuse' of discretion." '
[Citation.] An order that implicitly or explicitly rests on an erroneous reading of the law
necessarily is an abuse of discretion." (Williams v. Superior Court (2017) 3 Cal. 5th 531,
540.)
The trial court denied ReadyLink's motions to compel further discovery from
SCIF solely on the ground that ReadyLink was "seek[ing] to relitigate the exact same
issues already addressed before the Insurance Commission and the Court of Appeal." As
we have explained, the prior administrative and judicial proceedings did not decide the
issues that SCIF raises in its collection action.
We agree with ReadyLink that because the current action involves factual and
legal questions different from the issues that were decided in the prior administrative and
63
judicial proceedings, ReadyLink is entitled to discovery related to those questions.29 We
therefore conclude that the trial court erred in denying ReadyLink's motions to compel
and we reverse that order.

Outcome: The judgment of the trial court is reversed. The trial court's order denying
ReadyLink's motions to compel further discovery is also reversed. ReadyLink is entitled to costs on appeal.
