IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

SIXTH APPELLATE DISTRICT

ZENITH INSURANCE COMPANY H052785 et al., (WCAB No. ADJ13725280)

Petitioners,

v.

WORKERS’ COMPENSATION APPEALS BOARD and KIN CHAN,

Respondents.

In Mayor v. Workers’ Comp. Appeals Bd. (2024) 104 Cal.App.5th 713 (Mayor), review granted December 11, 2024, S287261, the First District Court of Appeal held that the Workers’ Compensation Appeals Board (WCAB, appeals board, or the Board) acted in excess of its jurisdiction when it granted a petition for reconsideration after expiration of the 60-day statutory deadline set out in former section 5909 of the Labor Code1 (Stats. 1992, ch. 1226, § 5, p. 5766) (former section 5909). Citing a similar decision in Zurich American Ins. Co. v. Workers’ Comp. Appeals Bd. (2023) 97 Cal.App.5th 1213

1 All further unspecified statutory references are to the Labor Code. (Zurich), the Court of Appeal in Mayor assumed without deciding that while equitable tolling might be available to avoid the running of the statutory deadline in limited cases, the facts of that case did not support the application of such an exception. (Mayor, at p. 1311.) In City of Salinas v. Workers’ Comp. Appeals Bd. (2025) 113 Cal.App.5th 801 (City of Salinas), review granted November 19, 2025, S293212, a panel of this court largely agreed with the analysis in Mayor and Zurich. This court further decided that the statutory timeframe for the grant or denial of a petition for reconsideration does not implicate the Board’s fundamental jurisdiction, allowing for the possibility of equitable tolling in a narrow class of cases. (Id. at pp. 826–827.) This court found such circumstances present in City of Salinas and affirmed the Board’s decision granting reconsideration. The California Supreme Court has granted review of this court’s decision in City of Salinas, holding the decision for its review of Mayor. The petition for writ of review in this case presents issues similar to those in City of Salinas, Mayor, and Zurich. Petitioners Zenith Insurance Company (Zenith) and New Sam Kee Restaurant, LLC (the restaurant) seek review of the appeals board’s order and decision after reconsideration. In that decision, the appeals board rescinded the order of the workers’ compensation administrative law judge (WCJ) denying compensation to respondent Kin Chan and substituted a new finding that Chan’s injury is not barred from compensation. Petitioners contend that the Board lacked jurisdiction to grant Chan’s petition for reconsideration, which was “deemed denied” by operation of former section 5909. Petitioners maintain, contrary to this court’s decision in City of Salinas, that equitable tolling is not available under former section

2 5909 as a matter of law. Petitioners assert in the alternative that, even if equitable tolling were available, the circumstances of this case do not warrant its application here. We decline to revisit the statutory analysis in City of Salinas and agree with petitioners that the Board exceeded its jurisdiction in granting Chan’s petition for reconsideration. We also agree with petitioners’ alternative argument that the narrow grounds for the Board to exercise equitable tolling have not been met in this case. We therefore reverse the order and decision of the appeals board. I. FACTS AND PROCEDURAL BACKGROUND A. Workers’ Compensation Claim At the time of his injury, Chan was an employee of the restaurant working as a prep cook. Chan’s coworkers included chef Ha Xu Huynh (Huynh)2, cashier and waiter Johnny Trieu (Trieu), and kitchen worker Kieu Luu (Luu). Chan and Huynh had worked together since approximately 2008. Trieu is the restaurant owner’s son. On September 15, 2020, Chan and Huynh were preparing dishes in the restaurant when they began to argue. The argument escalated. Huynh struck Chan in the right eye, causing a broken eye socket, among other injuries. Chan filed an application for workers’ compensation claim in October 2020. He alleged specific injuries to the eye and other body parts stemming from the workplace incident with Huynh. The restaurant and its insurance carrier, Zenith, filed an answer denying the allegations and asserting

2 Huynh is also referred to in the record as Ah Chuan.

3 affirmative defenses, including the “initial physical aggressor defense under” section 3600, subdivision (a)(7).3 (Capitalization omitted.) The matter proceeded to trial before the WCJ. The WCJ received evidence, including medical records documenting Chan’s injuries and treatment, and heard testimony from Chan, Huynh, Trieu, and Luu.4 The parties agreed that because Zenith and the restaurant had the burden of proof as to the initial physical aggressor defense, they presented testimony first. According to Chan, the incident occurred when Huynh began tossing vegetable and meat scrapings on to the restaurant kitchen’s worktable and yelling obscenities at him. Chan testified that he walked toward Huynh but did not yell or throw anything, nor did he have anything in his hands. As Chan tried to explain Huynh’s conduct to Trieu, Huynh stepped forward and struck Chan in the right eye. Huynh denied arguing with Chan. Huynh testified that he had complained about Chan’s ingredient preparation, and in response Chan insulted Huynh’s mother, threw a container at Huynh, and picked up a knife and came toward him. Although Trieu and the owner’s other son entered the kitchen and restrained Chan and Huynh, Chan hit Huynh on the head and

3 Section 3600, subdivision (a) provides, in relevant part, for workers’

compensation liability against an employer “for any injury sustained by his or her employees arising out of and in the course of the employment . . ., in those cases where the following conditions of compensation concur: [¶] . . . [¶] (7) Where the injury does not arise out of an altercation in which the injured employee is the initial physical aggressor.” 4 The testimony recounted herein is drawn from the WCJ’s detailed

minutes of the hearing and summary of evidence. No transcript of the hearing appears in the record on appeal. 4 Huynh hit him back, believing he was in danger and needed to defend himself. The other witnesses (Trieu and Luu) testified that there was an argument, though they did not know how it started, and that Chan approached Hunyh with a knife. Trieu testified that Chan came walking fast around the table towards Huynh with a knife in his hand, while Luu reported that Chan threw a dish across the worktable at Huynh, then pounded on the table with a knife and approached Huynh. Luu and Huynh each testified that they did not believe the presence of their employer (the restaurant owner) in the courtroom affected their testimony in any way. After trial, the WCJ issued written findings and order (findings and order), finding that Chan “sustained a specific injury” which “occurred during an affray with a co-worker in which [Chan] was the initial physical aggressor.” The WCJ ordered that Chan “shall take nothing by reason of this claim.” The WCJ discredited Chan’s and Huynh’s inconsistent narrations and self-described innocent conduct, finding that “the sworn testimony of neither [Chan] nor [Huynh] is credible enough to inspire confidence.” The WCJ found Luu and Trieu “generally credible,” noting their observations varied in only minor respects.
