The high-profile legal dispute came before the California Supreme Court on Monday, Aug. 24, with justices questioning whether Bianco had the legal authority to take custody of ballots from the county's election officials. The case places election administration, law-enforcement authority and the handling of election materials at the center of a closely watched legal battle.
Why the ballots were seized
Bianco's office seized approximately 650,000 ballots and about 1,000 boxes of election materials connected to a November 2025 special election concerning congressional redistricting. The proposition passed in Riverside County by roughly 80,000 votes.
The investigation began after a local citizens group alleged that the county's election results contained a significant discrepancy. According to reporting on the case, the group claimed there was a difference of more than 45,000 votes between certain records and the reported election totals. Local election officials rejected the allegation and said the complaint was unfounded.
Bianco nevertheless proceeded with the investigation and obtained search warrants that allowed his department to seize the election materials. He has maintained that the ballots could provide evidence needed to determine whether the alleged discrepancies were legitimate.
Sheriff says ballots remain evidence
At the heart of the dispute is Bianco's refusal to return the ballots after California Attorney General Rob Bonta challenged the seizure.
Bianco's position is that the ballots should remain preserved while the investigation and related legal proceedings are resolved. His defense has emphasized the role of law enforcement in investigating potential criminal conduct and argues that his department followed legal procedures when obtaining the warrants.
The sheriff has remained defiant even as the state's highest court considers the legality of his actions. According to the Associated Press, Bianco has characterized the seized ballots as legal evidence and has indicated that he would stand by his decision to investigate the allegations.
State officials challenge the seizure
Bonta has taken the opposite position, arguing that the sheriff does not have authority to take control of election materials that are held by county election officials.
The attorney general launched a legal challenge in March and ordered Bianco to return the ballots. Bianco did not comply, prompting further litigation. The UCLA Voting Rights Project also filed a separate lawsuit on behalf of Riverside County voters. Both legal challenges reached the California Supreme Court.
Bonta has warned that allowing a sheriff to independently seize election ballots could create a significant precedent for how elections are administered in California. His legal arguments focus not only on the specific seizure but also on the broader question of which government officials have custody and control over ballots after an election.
Supreme Court questions sheriff's authority
During Monday's arguments, several California Supreme Court justices appeared skeptical of Bianco's legal theory.
One of the central questions was whether state election law gives law enforcement different authority over ballots during an investigation than it does during a criminal prosecution. Justice Goodwin H. Liu reportedly described that argument as “bizarre” while questioning Bianco's attorney.
The justices' questions indicate that the court is examining more than whether Bianco believed he was investigating legitimate allegations. They are also considering whether the method used to obtain and retain the ballots complied with California's election laws and constitutional framework.
Recount was halted
Bianco's office began examining the seized materials, but the investigation did not proceed to a complete review of all the ballots.
A court-appointed special master was involved in overseeing the recount process, but the investigation was later halted after legal challenges. The California Supreme Court previously intervened to stop the investigation while the broader dispute over the seizure was litigated.
That means the legal question remains unresolved: whether the sheriff can retain the ballots as part of a criminal investigation or whether they must be returned to the officials responsible for maintaining election records.
Political implications add to the controversy
The dispute has attracted additional attention because Bianco was a candidate for California governor when the ballot seizure occurred. Critics have argued that his political campaign created an appearance of a conflict between law enforcement activity and electoral politics.
Supporters of the sheriff, meanwhile, have portrayed the investigation as an effort to examine claims about election integrity rather than an attempt to interfere with the election process.
The California Supreme Court's decision could therefore have consequences beyond Riverside County. A ruling in favor of the state could reinforce the authority of election officials over ballots and limit independent law-enforcement seizures. A ruling favoring Bianco could establish broader circumstances under which law enforcement can obtain and retain election materials during an investigation.
What happens next
The justices did not issue an immediate ruling following Monday's hearing. The court will now consider the arguments and determine whether Bianco must return the approximately 650,000 ballots.
For now, the ballots remain at the center of the legal dispute. Bianco continues to characterize them as evidence relevant to his investigation, while state officials argue that the sheriff exceeded his authority by taking custody of election materials.
The eventual ruling will determine not only the fate of the seized ballots but also how California's election materials may be handled when law enforcement seeks to investigate alleged irregularities after an election.
The key issue before the court is not whether election investigations are permitted, but whether a county sheriff has the legal authority to seize and retain ballots that are under the control of election officials.
