In a decision of considerable practical significance for California public employee unions and their members, the Court of Appeal for the Third Appellate District has reversed a trial court judgment that had limited an arbitrator’s remedial powers under a memorandum of understanding. The published opinion in Department of Human Resources v. California Correctional Peace Officers Association (2026 WL 1361422, filed May 15, 2026) clarifies that an arbitrator authorized to exercise the remedial authority of a Public Employment Relations Board ("PERB") administrative law judge may order rescission of a suspension previously upheld by the State Personnel Board, together with make-whole relief, where the award rests on a finding of retaliation for protected union activity rather than an attempt to supplant the SPB’s review on the merits. The ruling therefore preserves the vitality of concurrent or sequential grievance arbitration as a meaningful avenue for vindicating rights under the Ralph C. Dills Act even after the SPB has sustained discipline for cause.
Factual Background and Procedural History
Tracylyn Lopez, a correctional officer and CCPOA job steward at Salinas Valley State Prison, received a notice of adverse action for using profanity toward two fellow officers. After that matter was settled with a letter of reprimand, Lopez posted excerpts of the disciplinary materials on a union bulletin board visible to inmate workers, highlighting the surnames of the officers who had reported her. CDCR imposed a 60-workday suspension, which the SPB ultimately upheld on the ground that the posting promoted a “code of silence” and constituted inexcusable neglect of duty and failure of good behavior under Government Code section 19572, subdivisions (d) and (t).
Separately, Lopez filed a contractual grievance alleging that the suspension violated section 5.03 of the applicable MOU, which incorporates the Dills Act’s prohibitions on retaliation for protected union activity. CCPOA pursued the grievance to arbitration. The arbitrator found that CDCR had retaliated against Lopez for engaging in protected speech and representational activity, that the posting itself was not so opprobrious as to lose protection, and that CDCR failed to prove it would have imposed the same penalty absent the protected conduct. The arbitrator therefore ordered CDCR to rescind the notice of adverse action for the posting and to make Lopez whole through backpay and restoration of benefits and rights.
CDCR petitioned the superior court to vacate or correct the award, arguing that the arbitrator had exceeded her powers by interfering with the SPB’s constitutional authority to review disciplinary actions and by undermining public policy against the code of silence. The trial court denied the petition to vacate but granted the petition to correct, striking the provisions directing rescission and make-whole relief. CCPOA appealed.
The Court of Appeal’s Analysis
The Third District began from the well-established principle that judicial review of labor arbitration awards is extremely narrow, particularly in the public employment sector where strong policies favor collective bargaining and the finality of arbitral awards. An arbitrator exceeds her powers only in limited circumstances, including where the award violates an unwaivable statutory right or contravenes an explicit legislative expression of public policy. The public policy exception itself demands a two-part inquiry: identification of an explicit, clear, or well-defined and dominant expression of policy, followed by a determination that the award itself, not merely the underlying conduct, conflicts with that policy.
Applying this framework, the court concluded that the SPB’s constitutional authority under article VII, section 3, subdivision (a) to “review disciplinary actions” constitutes an explicit expression of public policy. Yet the arbitrator’s award did not contravene that policy. The SPB had reviewed the suspension for cause under the Civil Service Act and the merit principle; the arbitrator had examined whether the same discipline constituted retaliation for activity protected by the Dills Act and the MOU. These inquiries, while overlapping factually, are legally distinct. The SPB did not address the Dills Act claim, and the arbitrator did not purport to review or reverse the SPB’s determination on the merits. Instead, the award offset the suspension by providing a contractual remedy for the separate violation. Because enforcing one determination did not require violating the other, no inherent conflict arose.
The court similarly rejected the argument that the award undermined legislative and agency policies aimed at combatting the code of silence. While that policy is undoubtedly important, it does not mandate any particular length of suspension or preclude an arbitrator from finding that discipline was imposed for retaliatory reasons and ordering appropriate contractual relief. The award itself therefore did not conflict with an explicit expression of public policy.
Implications for PERB Retaliation Charges and Disciplinary Appeals Involving Overlapping Circumstances
This precedent confirms that civil service discipline and public sector retaliation claims (including those filed before PERB) proceed on separate but compatible tracks. An adminsitrative appeal ruling upholding discipline for cause does not, standing alone, preclude a finding from PERB (or an arbitrator in a grievance) that the same discipline violated a public sector labor statue (such as the MMBA or the Dills Act) or an MOU. PERB or the arbitrator can also order rescission and make-whole relief, notwithstanding the outcome of the disciplinary appeal. The appellate court noted that an award that offsets rather than purports to reverse or veto the SPB decision survives review and avoids the concerns raised in earlier authority such as State Personnel Bd. v. Department of Personnel Admin. (2005) 37 Cal.4th 512. Public sector unions may therefore pursue grievances and PERB unfair practices charges in appropriate cases without a favorable award automatically being judicially nullified on public policy grounds.
The decision also underscores the importance of preserving evidence of retaliatory motive and protected activity throughout the disciplinary process. Where emails, timing, or disparate treatment suggest anti-union animus, a well-developed record can support an offsetting remedy even after the disciplinary action has been upheld in the administrative appeal.
Considerations for POST Decertification Proceedings Under Senate Bill 2
It is important to distinguish the framework addressed in this case from the decertification process established by Senate Bill 2. Under that statutory scheme, the Commission on Peace Officer Standards and Training, through its Peace Officer Standards Accountability Division, conducts an independent investigation into allegations of serious misconduct as defined in Penal Code section 13510.8. The Commission applies a clear and convincing evidence standard, higher than the preponderance standard that typically governs most disciplinary appeal proceedings, and its review of the entire record is not automatically constrained by prior agency or arbitral findings.
A sustained finding against an officer in a disciplinary appeal or arbitration does not, by itself, relieve POST of its obligation to satisfy this heightened evidentiary threshold. POST remains required to prove its case independently under the clear and convincing standard, even where the SPB, a local civil service commission or an arbitrator has already found misconduct.
It bears repeating that the appellate case involved distinct legal questions: whether discipline was supported by cause under the Civil Service Act, on the one hand, and whether that same discipline constituted unlawful retaliation for protected activity under the Dills Act and the MOU, on the other. By contrast, a POST decertification proceeding under Senate Bill 2 will ordinarily address substantially the same legal question presented in the underlying disciplinary appeal, namely, whether the officer engaged in the alleged serious misconduct, albeit under the heightened clear and convincing evidence standard rather than the preponderance standard typically applied in disciplinary appeals. This distinction between overlapping versus distinct legal inquiries helps explain why the Court of Appeal found no public policy conflict in the arbitration award, while also illuminating why a favorable determination in a disciplinary proceeding may carry greater preclusive potential in a subsequent decertification matter.
By contrast, a favorable factual or legal determination rendered in favor of the officer in the disciplinary appeal on the same serious misconduct allegations could in appropriate circumstances give rise to collateral estoppel or res judicata. Where the traditional elements are satisfied, including identity of issues and sufficient privity between the employing agency and the Commission, such a finding may preclude POST from relitigating those matters in a subsequent decertification proceeding.
Conclusion
In light of this authority, an unsuccessful disciplinary appeal before the State Personnel Board does not preclude parallel unfair practice litigation. PERB would likely not be precluded from reviewing an upheld disciplinary action for unlawful retaliation under the MMBA, Dills Act, or other labor statute, nor would it be restricted in fashioning appropriate remedies for such violations. The Third District’s opinion represents a meaningful affirmation that carefully framed awards addressing retaliation will withstand judicial scrutiny.
