The decisions the statute sits on.

Viking River Cruises, Inc. v. Moriana#

596 U.S. 639 (2022)·U.S. Supreme Court · 2022

The Federal Arbitration Act preempts California's rule against dividing a PAGA action into individual and representative claims, so an employer may compel the individual component to arbitration. The Court further held that, once the individual claim is sent to arbitration, the plaintiff lacks statutory standing to maintain the representative claims in court, so they should be dismissed — but that holding rested on the Court's reading of then-existing California law, left for California's courts to confirm or reject.

BearingThe federal half of the arbitration-standing question that determines whether a penalty claim is litigated in court or carved apart.

Arias v. Superior Court#

46 Cal.4th 969 (2009)·Cal. Supreme Court · 2009

A PAGA action is a representative action brought on the State's behalf and need not satisfy class-action certification requirements.

BearingExplains why a single plaintiff's penalty claim can reach an entire workforce without class certification.

Iskanian v. CLS Transportation Los Angeles, LLC#

59 Cal.4th 348 (2014)·Cal. Supreme Court · 2014

A pre-dispute agreement to waive PAGA representative claims wholesale is unenforceable as against public policy; the FAA does not preempt that rule (the latter point since narrowed by Viking River as to the individual claim).

BearingThe foundation of PAGA's resistance to wholesale arbitration waivers, and the backdrop to Viking River and Adolph.

ZB, N.A. v. Superior Court#

8 Cal.5th 175 (2019)·Cal. Supreme Court · 2019

Labor Code § 558 authorizes a fixed civil penalty ($50/$100 per pay period) “plus an amount sufficient to recover underpaid wages.” The Court held that underpaid-wages component is recoverable only by the Labor Commissioner — it is not a civil penalty, and is not privately recoverable through PAGA at all. Employees pursue those unpaid wages through other statutes (e.g., § 1194). Only the § 558(a) fixed penalty is PAGA-recoverable.

BearingAnchors the line that PAGA penalties are not the employee's unpaid wages. Unpaid wages travel through wage claims and other remedies; PAGA collects civil penalties the State could have assessed.

Kim v. Reins International California, Inc.#

9 Cal.5th 73 (2020)·Cal. Supreme Court · 2020

An employee who settles and dismisses individual Labor Code claims still qualifies as an 'aggrieved employee' with standing to pursue PAGA penalties; PAGA standing does not depend on maintaining an unredressed individual injury.

BearingThe standing premise Adolph builds on — relevant to who may pursue a representative penalty claim.

Adolph v. Uber Technologies, Inc.#

14 Cal.5th 1104 (2023)·Cal. Supreme Court · 2023

Under California law a plaintiff compelled to arbitrate the individual PAGA claim retains standing to pursue the non-individual (representative) claims in court, rejecting the contrary suggestion in Viking River. Rested on the standing concept from Kim v. Reins.

BearingKeeps the representative penalty claim alive in court after arbitration of the individual claim — though built on pre-reform standing, an interaction the 2024 'personally suffered each' rule has not yet been tested against.

Estrada v. Royalty Carpet Mills, Inc.#

15 Cal.5th 582 (2024)·Cal. Supreme Court · 2024

Trial courts lack inherent authority to strike a PAGA claim as unmanageable, but retain ordinary tools to manage complex cases — limiting the evidence or the scope of claims at trial, and using representative or statistical proof. Disapproved Wesson v. Staples on the dismissal point.

BearingSets the manageability backdrop the reform then codified at § 2699(p) — the court's power to limit the evidence or scope of a claim so it can be effectively tried. (The neighboring § 2699(q) is a separate grant, addressing consolidation and coordination of related claims, not manageability.) Bears on how — and how much of — a large representative penalty claim is actually tried.

Huff v. Securitas Security Services USA, Inc.#

23 Cal.App.5th 745 (2018)·Cal. Court of Appeal · 2018

A plaintiff who suffered at least one Labor Code violation could pursue PAGA penalties for other violation types she did not personally suffer.

BearingAbrogated by the 2024 reform's 'personally suffered each of the violations alleged' standing rule (§ 2699(c)(1)); still governs notices filed before June 19, 2024.

Oswald v. Murray Plumbing & Heating Corp.#

82 Cal.App.5th 938 (2022)·Cal. Court of Appeal · 2022

Held that a construction-industry CBA tracking § 2699.6's language clearly waived PAGA and satisfied the section's requirements as a matter of law, reversing the denial of a motion to compel arbitration — and that a memorandum of understanding adopting the exemption's terms could apply retroactively to a pending suit.

BearingThe one published decision construing the § 2699.6 construction exemption. Decided under the pre-AB 1034 text, but AB 1034 changed only the sunset date — the qualifying-condition language Oswald applied is identical in the current section.

Rocha v. U-Haul Co. of California#

88 Cal.App.5th 65 (2023)·Cal. Court of Appeal · 2023

An arbitrator's confirmed finding that the employee suffered no Labor Code violation has issue-preclusive effect: it defeats the employee's status as an “aggrieved employee,” and with it standing to maintain the representative PAGA claim.

BearingThe settled pole of the arbitration-loss question — a total loss in the individual arbitration, once confirmed, ends the representative case. What remains open is how the 2024 “personally suffered each” rule shapes partial losses and narrowing.

Rodriguez v. Lawrence Equipment, Inc.#

106 Cal.App.5th 985 (2024)·Cal. Court of Appeal · 2024

Following Rocha: after the employer prevailed on every individual Labor Code claim in arbitration, judgment against the representative PAGA claim was affirmed — the arbitral findings precluded the plaintiff from establishing aggrieved-employee standing.

BearingConfirms Rocha's issue-preclusion rule in a published decision under the pre-reform standing text: losing the individual arbitration outright forecloses the representative claim.

Leeper v. Shipt, Inc.#

107 Cal.App.5th 1001 (2024)·Cal. Court of Appeal · 2024

Every PAGA action necessarily includes an individual PAGA claim, whether or not the complaint pleads one — so the individual component may be compelled to arbitration and the representative portion stayed. A plaintiff cannot avoid arbitration by pleading a “representative-only” action.

Review granted, Cal. Supreme Court No. S289305 (Apr. 16, 2025, on the court's own motion); fully briefed. Citable for persuasive value only while review is pending — Cal. Rules of Court, rule 8.1115(e)(1).

BearingThe anti-headless pole of the published split. The Supreme Court granted review to decide whether a representative-only (“headless”) PAGA action exists at all; its answer will control the split.

CRST Expedited, Inc. v. Superior Court#

112 Cal.App.5th 872 (2025)·Cal. Court of Appeal · 2025

A plaintiff may proceed solely on behalf of other aggrieved employees — a representative-only action — despite the dismissal of his own individual claims, keeping the action out of arbitration. (Partially published.)

Review granted and held for Leeper, No. S292005 (Sept. 17, 2025); depublication denied. Persuasive value only — Cal. Rules of Court, rule 8.1115(e)(3).

BearingA pro-headless pole of the published split, from the Fifth District.

Rodriguez v. Packers Sanitation Services Ltd., LLC#

109 Cal.App.5th 69 (2025)·Cal. Court of Appeal · 2025

A court looks to the face of the complaint: where only a representative PAGA claim is pleaded and no individual claim is alleged, there is no individual claim to compel to arbitration — a court will not read in a claim the plaintiff never pleaded.

Review granted and held for Leeper, No. S290182 (May 14, 2025). Persuasive value only — Cal. Rules of Court, rule 8.1115(e)(3).

BearingA pro-headless pole of the published split, from the Fourth District.

Williams v. Alacrity Solutions Group, LLC#

110 Cal.App.5th 932 (2025)·Cal. Court of Appeal · 2025

Agreeing with Leeper that every PAGA action includes an individual claim, held that a plaintiff whose individual claim was untimely under the one-year limitations period could not maintain a representative-only action — the time-barred individual component defeated the whole complaint.

Review granted and held for Leeper, No. S291199 (July 9, 2025). Persuasive value only — Cal. Rules of Court, rule 8.1115(e)(3).

BearingThe fourth published decision in the headless split, joining the anti-headless side and tying it to the one-year limitations period.
