Yuba County, California

The California Supreme Court heard oral arguments on whether Riverside County Sheriff Chad Bianco must return more than 650,000 ballots (over 1,400 boxes) seized in March from local election officials during an investigation into unsubstantiated fraud claims tied to a November special election on redistricting (Proposition 50). Justices appeared skeptical of arguments from Bianco's attorney, Bradley Hertz, who claimed sheriffs can seize ballots under warrant regardless of state election law, and that Attorney General Rob Bonta lacks authority to order sheriffs to stand down. Justices questioned both points, with one calling Hertz's reasoning "bizarre" and another "counterintuitive."

Bianco, a former Republican gubernatorial candidate, defied Bonta's order to halt the seizure and began counting ballots before the state Supreme Court intervened in April. Bianco said he would comply if ordered to return the ballots but may continue his investigation regardless. Voting rights advocates, including likely gubernatorial candidate Xavier Becerra, frame the case as a test of sheriff authority ahead of the 2026 midterms amid broader efforts by Trump-aligned officials to challenge election administration. A ruling is expected in coming months.
