SAN FRANCISCO (AP) — The California Supreme Court is weighing whether a Southern California sheriff who seized election ballots must return them to county election officials. The high court heard oral arguments Monday regarding Riverside County Sheriff Chad Bianco’s seizure of approximately 650,000 ballots from a November 2025 special election on redistricting. The measure passed in the county by roughly 80,000 votes.Bianco in March seized 1,000 boxes of election materials to investigate a complaint from a local citizens group that the count was off — though not by an amount that would’ve changed the outcome. Local election officials had previously said the complaint was unfounded. Bianco was running for governor at the time. Democratic Attorney General Rob Bonta immediately launched a legal challenge in March, arguing the sheriff has no authority over election materials and warning the seizure was designed to sow distrust in elections. He ordered Bianco to return the ballots, but Bianco did not. The University of California, Los Angeles Voting Rights Project also sued the sheriff on behalf of several Riverside County voters. The state Supreme Court heard arguments in both cases.

Chad Dunn, legal director and co-founder of the UCLA Voting Rights Project, told the court there are mechanisms to contest election results, and Bianco failed to follow them. “The elections code provides a process. Citizens could have triggered a recount within, I think, it’s five days of the canvas, and they chose not to do that. They could ask the Attorney General, the Secretary of State, and there’s other officials to trigger an official recount,” Dunn told the court.
