Background

Plaintiffs, the family members and Estate of Joseph Mendoza, brought California state and federal claims against the California Department of Corrections and Rehabilitation (CDCR), CDCR Secretary Jeff Macomber, Salinas Valley State Prison (SVSP) Warden Kelly Santoro, and former correctional Lieutenant Matthew Madsen arising from Mendoza's death in a gang-affiliated attack on April 8, 2025, while detained at SVSP. Plaintiffs alleged defendants were deliberately indifferent to Mendoza's safety by refusing to segregate or re-house him despite multiple requests, failing to intervene in the attack and provide medical aid, and recklessly disseminating video footage of the attack. They also alleged Madsen worked with Mendoza to introduce and distribute narcotics on behalf of the Norteño prison gang. Madsen was relieved from active duty in February 2025 and indicted in federal court in February 2026 for conspiracy to commit honest-services wire fraud for smuggling contraband into the prison.

Before the court were two partial motions to dismiss Plaintiffs' California state law claims for failure to comply with the California Government Claims Act (the Act). The Act requires claimants seeking monetary damages from a California public entity or its employees to first present a claim to that entity before filing suit. On April 22, 2025, the Estate, Ismael Mendoza, and Zina Kumetat filed a government claim with CDCR alleging one claim for wrongful death; Celina Mendoza was not listed. Plaintiffs received a written rejection on May 6, 2025. On July 30, 2025, all Plaintiffs filed an additional government claim with more detailed facts, additional state law claims, and additional claimants. Plaintiffs received no written response and initiated this action on December 1, 2025. Defendants argued Plaintiffs failed to file within the statute of limitations and failed to identify all individual defendants in their original government claims.

The Court’s Holding

The court first addressed the statute of limitations issue. It characterized the July 30 claim as an amendment to the April 22 claim rather than a duplicate, because it added more allegations, more claims, and more claimants. Under Cal. Gov't Code § 912.4(a), the government has 45 days to act on an amended claim; if it fails to act, the claim is deemed rejected on the 45th day, and a two-year limitations period from accrual of the cause of action applies. The court rejected Defendants' reliance on Sofranek v. County of Merced, which construed § 910.6(a) in a case with a written rejection, not § 912.4(a) governing deemed rejection. The court also found Plaintiffs substantially complied with the Act despite not checking the 'amendment' box on the claim form, because CDCR had sufficient information to investigate. Therefore, Plaintiffs' claims were not time-barred.

However, the court agreed with Defendants that Plaintiffs' original government claims failed to identify the individual defendants (Macomber, Santoro, and Madsen) as required by Cal. Gov't Code § 910(e). While Plaintiffs argued they did not know the identities at the time, this lack of knowledge was not pled in the complaint—Plaintiffs only alleged they 'timely presented their government claims.' The court held that on a motion to dismiss, it only considers facts pled in the complaint, not attorney arguments. Accordingly, the court granted the motions to dismiss the California state claims with leave to amend, requiring Plaintiffs to allege either compliance with the identification requirement or that the individual defendants' identities were unknown at the time of claim presentation. Plaintiffs' federal claims remain. Plaintiffs must file any amended complaint by November 12, 2026.

Key Takeaways

  • A second government claim that adds allegations, claims, and claimants constitutes an amendment under Cal. Gov't Code § 912.4(a), triggering a new 45-day period for government action and a two-year statute of limitations from accrual, even if the claimant does not check the 'amendment' box on the form.
  • Substantial compliance with the Government Claims Act is satisfied when the public entity has sufficient information to investigate, regardless of technical defects in the claim form.
  • Failure to name individual public employees in a government claim bars claims against them unless the complaint alleges their identities were unknown at the time of claim presentation.
  • Attorney arguments in briefing cannot substitute for factual allegations in the complaint on a Rule 12(b)(6) motion.
  • Leave to amend is freely granted under Ninth Circuit precedent unless the pleading could not possibly be cured by additional factual allegations.

Why It Matters

This decision clarifies the interplay between Cal. Gov't Code §§ 910.6(a) and 912.4(a) regarding amended claims and deemed rejection, holding that § 912.4(a) governs the government's response timeline for amended claims and restarts the limitations period when the government fails to act within 45 days. The ruling reinforces that substantial compliance with the Government Claims Act focuses on whether the public entity received adequate information to investigate, not on technical form requirements. However, it underscores the strict pleading requirement that plaintiffs must affirmatively allege in the complaint either that individual employees were named in the administrative claim or that their identities were unknown at the time—arguments raised only in opposition briefs are insufficient. The case remains pending on federal claims and any amended state law claims.
