The California Supreme Court has ordered Riverside County Sheriff Chad Bianco to pause his investigation into the 2025 Proposition 50 special election, which saw voters overwhelmingly approve a congressional redistricting plan spearheaded by Gov. Gavin Newsom. The court's decision comes after state Attorney General Rob Bonta filed a legal challenge to the sheriff's seizure of more than 611,000 ballots from the election.

Why it matters

The sheriff's investigation has raised concerns about undermining public confidence in the integrity of California's elections, with the state's top election official warning that the probe risks destabilizing the electoral process. The Supreme Court's intervention is seen as a necessary check on the sheriff's actions, which some have characterized as politically motivated.

The details

Bianco's office seized the ballots after a local Riverside County group alleged a possible discrepancy of about 45,800 votes between the California Secretary of State's count and the votes counted by electronic machines. However, local election officials say the actual discrepancy is much closer to 100 votes. Bianco has described the investigation as a "fact-finding mission" to physically count the ballots and compare the results to the reported totals.
