The California Supreme Court ruled on August 24, 2026, that the Workers' Compensation Appeals Board (WCAB) cannot extend the 60-day deadline to act on petitions for reconsideration. This decision affects workers like Joseph Mayor, who was seeking to enforce a disability award after the WCAB acted beyond the statutory deadline.
The case, Mayor v. Workers' Compensation Appeals Board and Ross Valley Sanitation District (docket number S287261), centers on the interpretation of Labor Code section 5909. This ruling is significant as it clarifies the limits of the WCAB's authority in handling reconsideration petitions, which could impact many workers' compensation cases in California.
Background
Joseph Mayor, a former employee of Ross Valley Sanitation District, was awarded total and permanent disability for an injury he sustained while working there in December 2013. Following this award, Ross Valley filed a petition for reconsideration on March 23, 2023. However, the WCAB did not act on this petition until 144 days later, claiming it did not receive notice of the petition until after the statutory deadline had passed.
Mayor challenged the WCAB's decision, arguing that the 60-day deadline for reconsideration was mandatory and jurisdictional. He contended that the WCAB acted beyond its authority by granting the petition after the deadline had elapsed. The Court of Appeal sided with Mayor, stating that the WCAB exceeded its jurisdiction by acting on the petition after the 60-day period.
The Ruling
The California Supreme Court affirmed the Court of Appeal's decision, agreeing that the deadline in section 5909 is mandatory and that the WCAB cannot equitably toll this deadline. Justice Evans authored the opinion, stating, "While there may be some narrow circumstances in which due process considerations could permit the Appeals Board to act outside of the 60-day deadline, Ross Valley has not asserted that its due process rights were violated."
The court clarified that the WCAB's failure to act within the 60-day timeframe meant that the petition for reconsideration was deemed denied, thereby upholding Mayor's original award of permanent disability. The ruling emphasized that the statutory deadline is not merely a guideline but a binding requirement that the WCAB must follow.
Impact
This ruling has significant implications for workers' compensation cases in California. It reinforces the importance of adhering to statutory deadlines and clarifies that the WCAB cannot extend these deadlines based on administrative delays or irregularities. Workers who seek reconsideration of awards can now have greater confidence that their cases will be resolved within the established timeframes.
The decision also sets a precedent for future cases involving the WCAB, emphasizing that the authority of the Board is limited by the statutory framework established by the Legislature. This ruling may deter the WCAB from attempting to extend deadlines in the future, ensuring a more predictable process for workers seeking justice in their claims.
What's Next
As of now, there are no indications that the ruling will be appealed. However, related cases may emerge as the implications of this decision unfold in the workers' compensation landscape. The clarity provided by this ruling may lead to further legislative discussions regarding the operation of the WCAB and its handling of reconsideration petitions.
