Victor Mendoza-Grado v. San Mateo County

Victor Mendoza-Grado v. San Mateo County · United States District Court for the Northern District of California · November 3, 2025 · No. 24-cv-09227-AMO

Summary

The United States District Court for the Northern District of California granted San Mateo County’s motion to dismiss Victor Mendoza-Grado’s claims. The court dismissed the 42 U.S.C. § 1983 claim with leave to amend because the complaint did not plausibly allege municipal liability under Monell, while dismissing the malicious prosecution claim without leave to amend because a plea, probation, and dismissal under California Penal Code § 1203.4 did not establish favorable termination. The court allowed Mendoza-Grado 30 days to file an amended complaint naming the Foster City Police Department and curing the identified deficiencies.

Holdings

  1. The complaint failed to state a § 1983 claim against San Mateo County because it did not plausibly allege that the constitutional injuries resulted from a County policy or longstanding custom, an act by a final policymaker, or ratification by a final policymaker.
  2. The § 1983 claim was dismissed with leave to amend because the plaintiff might be able to cure the pleading deficiencies by alleging additional facts against proper parties.
  3. Mendoza-Grado could not state a malicious-prosecution claim because his guilty or nolo contendere plea, completion of probation, and subsequent dismissal under California Penal Code § 1203.4 did not establish a favorable termination demonstrating factual innocence.

Questions Presented

  1. Whether the complaint plausibly alleged municipal liability against San Mateo County under 42 U.S.C. § 1983.
  2. Whether Mendoza-Grado could state a California malicious-prosecution claim when the underlying criminal case ended after his plea, completion of probation, and dismissal under California Penal Code § 1203.4.
  3. Whether leave to amend should be granted on either claim.

Disposition
