Case Explained: RAMIREZ V. RIVERSIDE COUNTY SHERIFF’S DEPARTMENT, ET AL.

Court: United States Court of Appeals for the Ninth Circuit Filed: 2026-08-04 Docket: 5:21-cv-01155-GW-ADS The ninth-circuit affirmed the district court’s grant of summary judgment for Sheriff Chad Bianco, Undersheriff Dennis Vrooman, and the County of Riverside in a 42 U.S.C. § 1983 action arising from a sewage overflow at the Cois Byrd Detention Center. The court applied de novo review and held that Ramirez failed to raise a genuine dispute of material fact regarding his supervisory liability claims against Bianco and Vrooman, as he could not demonstrate their personal involvement or a sufficient causal connection to the constitutional deprivation despite assuming a violation occurred. Additionally, the court affirmed the dismissal of Ramirez’s *Monell* claim against the County because he offered no evidence of a custom, policy, or insufficient training that caused the injury beyond the isolated incident itself. The practical consequence is that the judgment for the defendants stands and the case is closed. Do It For The Case Law is a news reporting service. Nothing in this episode constitutes legal advice.
