The trial court denied the petition of appellant Ralphs Grocery Company 

(Ralphs) to compel arbitration of a wage dispute with its former employee, 

respondent Stephanie Rabb Mahmud, relying on the four-factor test set forth in 

Gentry v. Superior Court (2007) 42 Cal.4th 443 (Gentry). While the appeal was 

pending, the California Supreme Court held in Iskanian v. CLS Transportation Los 

Angeles, LLC (2014) 59 Cal.4th 348 (Iskanian) that Gentry had been abrogated by 

the United States Supreme Court’s decision in AT&T Mobility LLC v. Concepcion

(2011) 563 U.S. __ [131 S.Ct. 1740] (Concepcion). As the legal rationale that 

formed the basis for the trial court’s ruling has been abrogated and Mahmud 

presented no other basis for denial of the petition to compel, we reverse.

FACTUAL AND PROCEDURAL BACKGROUND

A. Complaint

In March 2009, Mahmud brought suit alleging that Ralphs violated 

provisions of the state Labor Code requiring employers to provide employees meal 

breaks, to allow rest periods, to pay for unused accrued vacation time upon 

termination, and to pay all wages owed upon termination. Respondent sought 

certification of multiple classes of similarly situated Ralphs’ employees, including 

a meal period class, a rest period class, and a final wages class. 

B. Prior Proceedings

1. Petition to Compel Arbitration

Ralphs petitioned to compel arbitration of the dispute. Ralphs presented 

evidence that in February 2008, Mahmud had signed an application for 

employment stating that she “acknowledge[d] and underst[ood]” Ralphs had a 

dispute resolution program that included a Mediation & Binding Arbitration Policy 

[Arbitration Policy] which applied to “all employees and applicants for 
3

employment,” and to “any employment-related disputes that exist or arise between 

Employees and [Ralphs] that would constitute cognizable claims or causes of 

action in a court or government agency under applicable law including individual 

statutory claims or disputes.” In signing the application, Mahmud agreed to be 

“bound by the provisions, terms, and conditions of the [Arbitration] Policy” and to 

waive her right to a judge or jury trial or to litigate proceedings in a local, state or 

federal court or agency. 

Ralphs’ Arbitration Policy defined covered disputes as “employment-related 

disputes [¶]. . . [¶] which involve the interpretation or application of the Arbitration 

Policy, the employer/employee relationship, an Employee’s actual or alleged 

employment with Ralphs . . . , the termination of such employment, or applying for 

or seeking such employment.” It provided that arbitration proceedings would be

governed by the Federal Arbitration Act (9 U.S.C. § 1 et seq., FAA), the Federal 

Rules of Civil Procedure, and the Federal Rules of Evidence, except that there 

were no “class actions or Representative Actions permitted.” It further stated: 

“[T]here is no right or authority for any Covered Disputes to be heard or arbitrated 

on a class action basis, as a private attorney general, or on bases involving claims 

or disputes brought in a representative capacity on behalf of the general public, or

other Ralphs employees (or any of them), or of other persons alleged to be 

similarly situated.” 

2. Mahmud’s Opposition

In opposing the petition to compel arbitration, Mahmud raised three 

arguments. She contended the arbitration agreement was unenforceable under 

Gentry, supra, 42 Cal.4th 443, in which the California Supreme Court had held 

that where “the prohibition of classwide relief would undermine the vindication of 

the employees’ unwaivable statutory rights and would pose a serious obstacle to 
4

the enforcement of the state’s overtime laws,” and where the trial court determines 

that classwide adjudication “would be a significantly more effective way of 

vindicating the rights of affected employees than individual arbitration,” the class 

action waiver should not be enforced. (Id. at p. 450.) The Supreme Court had 

stated in Gentry that in determining whether to enforce a contractual class action 

waiver, the trial court should consider four factors: “[(1)] the modest size of the 

potential individual recovery, [(2)] the potential for retaliation against members of 

the class, [(3)] the fact that absent members of the class may be ill informed about 

their rights, and [(4)] other real world obstacles to the vindication of class 

members’ rights to overtime pay through individual arbitration.” (Id. at p. 463.) 

Mahmud presented evidence that the individual damages for the Labor Code 

violations alleged in the complaint would be insufficient to support separate 

litigation by each wronged employee, that she had been unaware of her rights 

under the Labor Code with respect to meal breaks and rest periods during her 

employment, and that employees who complained about working conditions were 

fired or treated badly. 

Mahmud also contended Ralphs was collaterally estopped from enforcing 

the arbitration agreement based on an unpublished decision in an earlier litigation,

in which the Court of Appeal had held that similar provisions in Ralphs’ 2001, 

2003 and 2004 Arbitration Policy precluding all class actions rendered the 

arbitration agreements signed by the plaintiffs in that litigation unconscionable.

1 An unpublished opinion may be cited or relied on when it is relevant under the 

doctrines of law of the case, res judicata or collateral estoppel. (Rules of Court, rule 

8.1115(b)(1).) The case on which Mahmud then relied to support collateral estoppel --

Massie v. Ralphs Grocery Co. (May 14, 2007, B187844) 2007 Cal.App.Unpub. LEXIS

3818 -- was decided prior to the Supreme Court’s decision in Gentry, and relied primarily 

on the pre-Gentry decision Discover Bank v. Superior Court (2005) 36 Cal.4th 148, 

abrogated in Concepcion, supra, 563 U.S. __ [131 S.Ct. 1740]. The matter was 

(Fn. continued on next page.)
5

Finally, Mahmud contended that the arbitration agreement was “tainted with 

illegality” because it prohibited an employee from acting as a private attorney 

general under the Private Attorneys General Act of 2004 (Labor Code, § 2699 et 

seq. (PAGA)).2 Mahmud did not assert that any provision of the arbitration 

agreement other than the class action prohibition rendered it unenforceable or 

substantively unconscionable. She presented no evidence concerning the 

circumstances under which she signed the agreement or any other facts pertinent to 

the issue of procedural unconscionability.

3

Relying on Gentry, the trial court found the class action waiver 

unenforceable because there was no practical way to vindicate the potential 

claimants’ statutory rights outside of class litigation, due to the large number of 

claimants with relatively small claims. Ralphs appealed.

 

remanded for reconsideration in light of Gentry (see McLeod v. Ralphs Grocery Co. 

(April 7, 2008, B187854) 2008 Cal.App.Unpub. LEXIS 2839, went through a second 

appeal after the trial court found the existence of the four Gentry factors, and was 

affirmed. (Massie v. Ralphs Grocery Co. (April 2, 2012, B224196) 2012 

Cal.App.Unpub. LEXIS 2508.) Mahmud no longer relies on Massie.

2

In PAGA, the Legislature created a mechanism for aggrieved employees to file 

representative actions to recover penalties from employers; the statute acts as an 

alternative to enforcement of the Labor Code by the Labor Commissioner. (Rope v. 

Auto-Chlor System of Washington, Inc. (2013) 220 Cal.App.4th 635, 650; Dunlap v. 

Superior Court (2006) 142 Cal.App.4th 330, 337.) Mahmud raised this contention 

although she had asserted no PAGA claim in her complaint, and did not seek to litigate 

the matter as a representative nonclass action under PAGA.

3 As explained in Pinnacle Museum Tower Assn. v. Pinnacle Market Development 

(US), LLC (2012) 55 Cal.4th 223, 246 (Pinnacle Museum): “Unconscionability consists 

of both procedural and substantive elements. The procedural element addresses the 

circumstances of contract negotiation and formation, focusing on oppression or surprise 

due to unequal bargaining power. [Citation.] Substantive unconscionability pertains to 

the fairness of an agreement’s actual terms and to assessments of whether they are overly 

harsh or one-sided. [Citations.]” 
6

3. Prior Appeal

While the prior appeal was pending the United States Supreme Court 

rendered its decisions in Preston v. Ferrer (2008) 552 U.S. 346 (Preston) and 

Stolt-Nielsen S.A. v. AnimalFeeds Int’l Corp. (2010) 559 U.S. 662 (Stolt-Nielsen). 

In Preston, the court held that the California Talent Agencies Act (Labor Code, 

§ 1700 et seq.), which granted the Labor Commissioner exclusive original 

jurisdiction to determine the validity of an agreement between an entertainer and 

an unlicensed individual or entity purporting to act as a talent agent, was 

preempted by the FAA when the parties had agreed to arbitrate all questions 

arising under their contract. (Preston, supra, at p. 359.) Stolt-Nielsen held that “a 

party may not be compelled under the FAA to submit to class arbitration unless 

there is a contractual basis for concluding that the party agreed to do so.” (StoltNielsen, supra, at p. 684, italics omitted.) Ralphs contended these decisions

undermined Gentry and required reversal of the trial court’s order. By opinion 

filed January 5, 2011, we concluded the trial court’s ruling was appropriate under 

Gentry and not inconsistent with either decision. Accordingly, we affirmed the 

order denying Ralphs’ petition.

C. Proceedings After Remand

After remand, Ralphs filed a renewed petition to compel arbitration,

contending that the United States Supreme Court’s opinion in Concepcion, supra,

131 S.Ct. 1740 effectively overruled Gentry. In Concepcion, the Supreme Court 

reversed a Ninth Circuit decision that had concluded, relying on the California 

Supreme Court’s decision in Discover Bank v. Superior Court, supra, 36 Cal.4th 

148, that an arbitration provision in a consumer contract that forbade classwide 

arbitration was unconscionable where it appeared from the allegations of the 

complaint that a large group of consumers had been cheated out of a small sum. 
7

The United States Supreme Court abrogated the Discover Bank rule, concluding it

was preempted by the FAA because it interfered with arbitration. (Concepcion, 

supra, 131 S.Ct. at p. 1750.) According to the court: “Requiring the availability of 

classwide arbitration interferes with fundamental attributes of arbitration and thus 

creates a scheme inconsistent with the FAA.” (Id. at p. 1748.) 

Mahmud opposed the renewed motion. Her opposition raised only two 

points. First, she contended that Concepcion had not abrogated or overruled 

Gentry. Second, she contended that Ralphs’ arbitration agreement violated federal 

common law and the National Labor Relations Act (29 U.S.C. § 151 et seq., 

NLRA) because it precluded employees from engaging in concerted activity.4

Mahmud did not raise collateral estoppel as a basis for denying the motion.

5

 

Mahmud presented no facts to support procedural unconscionability, and raised no 

challenge to any provision of the arbitration agreement other than the class action 

waiver.

The trial court denied the renewed motion. This appeal followed.

 

4 Mahmud also contended that bars against representative PAGA actions were 

unenforceable under federal common law and violated the NLRA. Although Mahmud 

had filed a first amended complaint in September 2009, making minor changes to 

conform her unfair competition claim to the law, she had still not asserted a PAGA claim. 

5

The opposition did cite Brown v. Ralphs Grocery Co. (2011) 197 Cal.App.4th 489, 

but only for the proposition that Gentry remained the law post-Concepcion. In Brown, 

however, the appellate court found that the plaintiff had failed to carry her evidentiary 

burden under the four-factor test established in Gentry, and did not determine “whether, 

under [Concepcion], the rule in [Gentry] concerning the invalidity of class action waivers 

in employee-employer contract arbitration clauses is preempted by the FAA.” (Brown, 

supra, 197 Cal.App.4th at pp. 497-498.) Because the plaintiff in Brown sought to act as a 

private attorney general, the court remanded for the trial court to consider whether the 

PAGA waiver provision in the arbitration agreement could be severed and the remainder 

of the agreement enforced according to its terms. (Brown, supra, at pp. 503-504.) As 

Mahmud asserted no PAGA claim, the holding in Brown is not relevant here.
8

DISCUSSION

In their original briefs, the parties debated whether Concepcion abrogated 

Gentry and whether the NLRA precluded enforcement of the agreement due to the 

ban on class actions.

6

 As these issues were raised in fully briefed cases pending 

before the California Supreme Court, we stayed the appeal until our Supreme 

Court could make its position known. In Iskanian, supra, 59 Cal.4th 348, the court 

held that “[u]nder the logic of Concepcion, the FAA preempts Gentry’s rule 

against employment class waivers.” (Id. at p. 364.) The court explained: “[T]he 

fact that Gentry’s rule against class waiver is stated more narrowly than Discover 

Bank’s rule does not save it from FAA preemption under Concepcion. The high 

court in Concepcion made clear that even if a state law rule against consumer class 

waivers were limited to ‘class proceedings [that] are necessary to prosecute smalldollar claims that might otherwise slip through the legal system,’ it would still be 

preempted because states cannot require a procedure that interferes with 

fundamental attributes of arbitration ‘even if it is desirable for unrelated reasons.’ 

[Citations.] It is thus incorrect to say that the infirmity of Discover Bank was that 

it did not require a case-specific showing that the class waiver was exculpatory. 

Concepcion holds that even if a class waiver is exculpatory in a particular case, it 

is nonetheless preempted by the FAA.” (Iskanian, supra, at p. 364, quoting 

Concepcion, supra, 131 S. Ct. at p. 1753.)

The Supreme Court also considered whether the class action waiver was 

invalid under the NLRA and concluded in light of the FAA’s “‘liberal federal 

policy favoring arbitration”’ (Concepcion, supra, 131 S. Ct. at p. 1745), that 

sections 7 and 8 of the NLRA do not represent “‘“a contrary congressional 

 

6 Mahmud contended in her brief that the bar against PAGA also violated the 

NLRA. She cited no authority for this proposition, however, and we deem it forfeited.
9

command””’ “overriding the FAA’s mandate [citation].” (Iskanian, 59 Cal.4th at 

p. 373.) The Supreme Court observed that its conclusion was “consistent with the 

judgment of all the federal circuit courts and most of the federal district courts that 

have considered the issue.” (Ibid., citing Sutherland v. Ernst & Young LLP (2d 

Cir. 2013) 726 F.3d 290, 297, fn. 8; Owen v. Bristol Care, Inc. (8th Cir. 2013) 702 

F.3d 1050, 1053-1055; Delock v. Securitas Security Services USA, Inc. (E.D.Ark. 

2012) 883 F.Supp.2d 784, 789-790; Morvant v. P.F. Chang’s China Bistro, Inc. 

(N.D.Cal. 2012) 870 F.Supp.2d 831, 844-845; Jasso v. Money Mart Express, Inc. 

(N.D.Cal. 2012) 879 F.Supp.2d 1038, 1048-1049.)7 

In light of the Supreme Court’s binding conclusion that Gentry was no 

longer good law and that the NLRA did not override the FAA, we asked the parties 

for additional briefing. In her supplemental brief, Mahmud argued for the first 

time that Ralphs is collaterally estopped from litigating the enforceability of its 

arbitration agreement based on Chavarria v. Ralphs Grocery Co. (9th Cir. 2013) 

733 F.3d 916, in which the Ninth Circuit affirmed a district court’s determination 

that procedural and substantive unconscionability precluded enforcement of the

Arbitration Policy. We need not address this issue. “[C]ollateral estoppel must be 

raised in the trial court . . . and is waived if not raised below [citation].” (People v. 

Gillard (1997) 57 Cal.App.4th 136, 160; accord, Franklin Mint Co. v. Manatt, 

Phelps & Phillips, LLP (2010) 184 Cal.App.4th 313, 333, fn. 9 [court declined to 

 

7

The Supreme Court also pointed out that the arbitration agreement at issue

“permit[ted] a broad range of collective activity to vindicate wage claims”: it did not 

“prohibit employees from filing joint claims in arbitration,” “preclude the arbitrator from 

consolidating the claims of multiple employees,” or “prohibit the arbitrator from 

awarding relief to a group of employees.” Nor did it “restrict the capacity of employees 

to ‘discuss their claims with one another, pool their resources to hire a lawyer, seek 

advice and litigation support from a union, solicit support from other employees, and file 

similar or coordinated individual claims.’” (Iskanian, supra, 59 Cal.App.4th at p. 374.)
10

take judicial notice of materials from prior lawsuit to determine collateral estoppel, 

finding absence of “exceptional circumstances” to justify judicially noticing 

“matters that were not presented to the trial court”].) In neither her opposition to 

Ralphs’ renewed motion to compel arbitration nor her opening brief did Mahmud 

raise collateral estoppel or cite Chavarria, although the district court’s decision in 

Chavarria was issued weeks prior to the filing date of her opposition and a year 

prior to the filing date of her respondent’s brief on appeal. (See Chavarria v. 

Ralphs Grocer Co. (C.D. Cal. 2011) 812 F.Supp.2d 1079 [filed September 15, 

2011].)8 

Moreover, confidence in the correctness of the prior judgment for purposes 

of collateral estoppel is subject to doubt where “a determination relied on as 

preclusive is itself inconsistent with some other adjudication of the same issue.” 

(Sandoval v. Superior Court (1983) 140 Cal.App.3d 932, 941.) In Macias v. 

Ralphs Grocery Co. (August 28, 2008, B202625) 2008 Cal.App.Unpub. LEXIS 

6960, the court considered substantially the same Arbitration Policy as in 

Chavarria and reached a contrary conclusion regarding unconscionability. (See 

also Covarrubias v. Ralph’s Grocery Co. (N.D. Cal. 2004, September 7, 2004, No. 

C 02-5465 JSW) 2004 U.S. Dist. LEXIS 18318 [referencing prior order finding 

plaintiff’s arbitration agreement with Ralphs binding, enforceable and not 

unconscionable].)

Finally, even were we inclined to overlook the waiver and address 

unconscionability on the merits, Mahmud could not prevail on the record before 

us. As the California Supreme Court stated in Pinnacle Museum, supra, 55 Cal.4th 

 

8 A final district court judgment retains its collateral estoppel effect while the appeal 

is pending. (Collins v. D.R. Horton, Inc. (9th Cir. 2007) 505 F.3d 874, 882; accord, 

Tripati v. Henman (9th Cir. 1988) 857 F.2d 1366, 1367.)
11

223, the party resisting arbitration bears the burden of presenting evidence to 

support both procedural and substantive unconscionability, which are evaluated on 

a “‘“sliding scale”’”: “‘[T]he more substantively oppressive the contract term, the 

less evidence of procedural unconscionability is required to come to the conclusion 

that the term is unenforceable, and vice versa.’” (55 Cal.4th at pp. 246-247; see 

Armendariz v. Foundation Health Psychcare Servs. (2000) 24 Cal.4th 83, 114,

italics omitted, quoting Stirlen v. Supercuts, Inc. (1997) 51 Cal.App.4th 1519, 1533

[procedural and substantive unconscionability “‘must both be present in order for a 

court to exercise its discretion to refuse to enforce a contract or clause under the 

doctrine of unconscionability’”].) Procedural unconscionability focuses on the 

circumstances surrounding the execution of the agreement: lack of negotiation, 

lack of meaningful choice, or insertion of arbitration terms in small type in a prolix 

printed form. (See, e.g., Crippen v. Central Valley RV Outlet (2004) 124 

Cal.App.4th 1159, 1165.) Unlike the plaintiff in Chavarria, Mahmud presented no 

evidence of the circumstances surrounding her application for employment or her 

decision to sign the arbitration agreement. Even after the United States Supreme 

Court’s decision in Concepcion called Gentry into question and led Ralphs to 

renew its petition to compel arbitration, Mahmud chose to base her opposition 

entirely on the four Gentry factors, providing neither a declaration nor other

evidence to support unconscionability on any other ground. In the absence of such

evidence, we will not presume procedural unconscionability.

Alternatively, Mahmud contends Ralphs’ Arbitration Policy is 

unconscionable “under [the California Supreme Court’s decision in] SonicCalabasas A., Inc. v. Moreno (2013) 57 Cal.4th 1109 (Sonic II).” She cites no 

provisions of the policy to support that contention, however, and advances no 

argument explaining how any of the arbitration procedures set forth in the policy 
12

demonstrate unconscionability under the standards set forth in Sonic II.

9

She 

suggests no evidence she could have presented to address the “fact specific 

inquiry” mandated in Sonic II. “An appellant must affirmatively demonstrate error 

through reasoned argument, citation to the appellate record, and discussion of legal 

authority.” (Bullock v. Philip Morris USA, Inc. (2008) 159 Cal.App.4th 655, 685.) 

“‘The reviewing court is not required to make an independent, unassisted study of 

the record in search of error or grounds to support the judgment.’ [Citations.]” 

(Guthrey v. State of California (1998) 63 Cal.App.4th 1108, 1115, quoting 9 

Witkin, Cal. Procedure (4th ed. 1997) Appeal, § 594, p. 627.) Where “an appellant 

fails to raise a point, or asserts it but fails to support it with reasoned argument and 

citations to authority,” we treat the point as forfeited. (Badie v. Bank of America

(1998) 67 Cal.App.4th 779, 784-785; accord, Nelson v. Avondale Homeowners 

Assn. (2009) 172 Cal.App.4th 857, 862.) Any contention appellant may have had 

with respect to Sonic II is forfeited. 

 

9

In Sonic II, the employer unsuccessfully petitioned the superior court to compel 

arbitration of an ex-employee’s administrative wage claim. The California Supreme 

Court held that in determining the unconscionability of an adhesive employment-related 

arbitration agreement that precludes assertion of administrative claims, a court may 

consider whether the employee has been provided an accessible and affordable forum for 

effective wage dispute resolution, similar to that provided under the Labor Code for a 

Berman hearing. (Sonic II, supra, 57 Cal.4th at p. 1146; see Labor Code § 98, et seq.,

Post v. Palo/Haklar & Associates (2000) 23 Cal.4th 942, 946-947.) The court further 

held that “a finding of unconscionability” under this rule “requires a court to examine the 

totality of the agreement’s substantive terms as well as the circumstances of its formation 

to determine whether the overall bargain was unreasonably one-sided,” a “fact-specific 

inquiry.” (Sonic II, supra, at p. 1146.)

DISPOSITION

The order denying Ralphs’ petition to compel arbitration is reversed. The 

matter is remanded for entry of an order granting the petition. Ralphs is awarded 

costs on appeal.
