California State Sheriffs' Association says the Attorney General cannot nullify a sheriff's lawful investigation
California State Sheriffs' AssociationProfessional association of California sheriffs; amicus curiae supporting Sheriff Bianco in Bonta v. Bianco
In an amicus brief supporting Sheriff Bianco, the California State Sheriffs' Association said the case asks whether the Attorney General may "unilaterally interfere with, terminate, or nullify" a sheriff's "lawful criminal investigation conducted pursuant to search warrants issued by a neutral magistrate", and argued that disagreement with an investigation does not amount to constitutional authority.
Responding to
The Attorney General has no legal authority to order a sheriff to halt or pause a lawful criminal investigation.
“Boiled down, the case asks a single fundamental question: Whether the Attorney General may unilaterally interfere with, terminate, or nullify a sheriff’s lawful criminal investigation conducted pursuant to search warrants issued by a neutral magistrate. … The Attorney General may disagree with the underlying investigation, but disagreement does not, and should not, amount to constitutional authority.”

Where this statement fits
Was Riverside County Sheriff Chad Bianco's seizure of about 650,000 ballots lawful?
Riverside County Sheriff Chad Bianco's department obtained search warrants in February and March 2026 and, on February 26, seized about 650,000 ballots from the November 2025 Proposition 50 special election from the county registrar of voters. Bianco said he was investigating a discrepancy of 45,896 ballots reported by a citizens' group; Registrar Art Tinoco said the reported gap reflected a misreading of preliminary records and that the actual variance was 103 ballots. Attorney General Rob Bonta directed Bianco on February 26 to preserve the materials and pause the investigation, and sued after Bianco said on March 20 that it would continue despite the Attorney General's attempts to stop it. On September 24, 2026, the California Supreme Court unanimously held in Cervantes v. Bianco that the seizure violated Elections Code section 15551(d) and ordered the ballots returned, and held in Bonta v. Bianco that the Attorney General may give a sheriff binding directions about an investigation. Bianco says the investigation was lawful and that he disagrees with the rulings, but has said he will obey the court's writs; the court did not resolve whether the claimed discrepancy exists.
