California Appellate Court Won’t Stop Riverside Sheriff’s Ballot Probe; AG Says Denial Was Procedural

A California appellate court refused Attorney General Rob Bonta’s request to halt Riverside County Sheriff Chad Bianco’s probe into alleged 2025 Proposition 50 ballot discrepancies, denying relief on procedural grounds while legal challenges continue nationwide.

Key takeaways

  • The appellate court denied Attorney General Bonta’s request to stop the ballot investigation — a decision the AG’s office says was tied to CalMatters where the petition was filed, not the merits of the case.
  • Sheriff Chad Bianco seized more than 650,000 ballots tied to Proposition 50 and says the count addresses alleged discrepancies raised by a local group; county officials and experts dispute large-scale discrepancies (Los Angeles Times, LAist).
  • Legal fights continue: the UCLA Voting Rights Project petitioned the California Supreme Court for return of ballots while warrants remain under seal and authorities weigh further steps (Los Angeles Times).

What the appellate order said — and what it did not

The court’s ruling did not adjudicate the underlying legality of Sheriff Bianco’s actions. Instead, the denial focused on procedural posture — specifically, where the Attorney General filed the petition — a point the AG’s office emphasized in its response. In its statement the AG’s office said the refusal was “based solely on where we filed the case” and clarified the decision was not a ruling on the facts or law of the allegations (CalMatters).

Bonta’s arguments

Attorney General Rob Bonta argued the investigation lacked probable cause and that the warrants authorizing the seizure “failed to meet even the most basic constitutional and statutory standards.” Bonta described the sheriff’s actions as “brazen, ongoing violations” of state law and sought an expedited order to halt Bianco’s handling of election materials while courts weigh in (CalMatters).

Sheriff Bianco’s account and defense

Sheriff Chad Bianco framed the operation as a fact-finding law-enforcement review: “Physically count the ballots and compare that result with the total votes reported,” he said at a press conference, insisting the action is separate from a recount and denying political motives. Bianco’s office has characterized critical coverage as misleading and accused Democratic officials of attempting to stop the probe (Los Angeles Times).

“This is simple, we are counting ballots, not yes and no votes. This is not a recount, it is a count of ballots plain and simple,” Bianco’s office said in a statement.

Claims, evidence and expert views

The complaint at the center of the investigation came from the Riverside Election Integrity Team, which alleged roughly 45,800 more votes were reported to the state than the county’s ballot logs recorded. Bianco cited that figure as justification for the seizure. County elections staff and independent experts, however, report far smaller differences — county officials say machine and final counts differed by about 100 votes — and election experts question whether local law enforcement has the authority or expertise for such operations (LAist; Los Angeles Times).

Secretary of State Shirley Weber said the allegations “lack credible evidence and risk undermining public confidence in our elections,” and officials noted Bianco and deputies are not trained election administrators, raising chain-of-custody and process concerns (Los Angeles Times; CyberScoop).

County registrar’s response and legal filings

The Riverside County Registrar of Voters said the office will comply with lawful court orders and protect the integrity of the canvass. Meanwhile, the UCLA Voting Rights Project filed a petition with the California Supreme Court requesting the return of seized ballots so county officials can complete certification without interference; warrants authorizing the seizure remain under seal (Los Angeles Times).

Political backdrop and national echoes

Observers note parallels to post-election controversies elsewhere, including investigations in Georgia and Arizona. Some supporters frame Bianco’s actions as ensuring transparency; critics warn that high-profile seizures tied to political actors can erode trust without producing substantiated evidence (Democracy Docket).

Bianco is also a gubernatorial candidate. Polling shows a crowded field; a UC Berkeley-Politico poll and an Emerson College poll place Democratic and independent figures ahead, with Bianco trailing among several contenders and registering around the low double digits in some samples. Bianco maintains the probe is separate from his campaign activities.

Key legal questions include whether the warrants were properly issued, whether a sheriff can lawfully seize and retain election materials during an official canvass, and whether chain-of-custody or certification processes were disrupted. Courts will consider sealed warrants, jurisdictional questions and statutory authority as challenges proceed. The AG’s office said it is evaluating next steps after the appellate court’s procedural denial (CalMatters).

Broader implications

Economic: Immediate fiscal effects are limited, but prolonged litigation can divert county and state resources to legal fees and operational costs, potentially affecting services and local confidence (Los Angeles Times).

Political and social: The case sharpens debates over election authority and the role of law enforcement in election disputes, with implications for public trust and precedent-setting court rulings. Officials from both sides urge adherence to legal standards and transparent communications to preserve voter confidence (CyberScoop).

Practical note for voters and officials

Expect ongoing filings and possible court orders clarifying who may handle ballots and under what conditions. County officials say they will follow lawful orders while protecting the canvass. Authorities nationwide may revisit chain-of-custody rules and interagency coordination to avoid similar conflicts.
