US Midterms 2026Background
Bonta v. Bianco is the companion to Cervantes v. Bianco. Deciding both on 24 September 2026, the Supreme Court of California upheld Attorney General Rob Bonta's order that Riverside County Sheriff Chad Bianco pause his investigation into the 2025 Proposition 50 count.
Chief Justice Patricia Guerrero wrote for a unanimous court in case S295901. The state constitution names the attorney general the chief law officer, with 'direct supervision over every district attorney and sheriff', and Government Code section 12560 lets the attorney general direct a sheriff's investigation in the public interest. the Court said it had not ruled on such a dispute in almost a century of those provisions. It held that the attorney general may give binding directions on a particular investigation, upheld orders to pause, preserve seized items and hand over documents, and rejected Bianco's claim that Bonta had a conflict of interest for calling the inquiry 'baseless'.
The decision gives California a tested state-level check on any sheriff WHO treats an election dispute as a criminal matter.
