The guardrails hold

For Pasadena voters accustomed to filling out a ballot at the kitchen table, dropping it in the mail or a ballot box, and knowing their vote is on its way to being counted, Monday night brought welcome clarity.

The U.S. Supreme Court rejected the Trump administration’s request to put new restrictions on mail-in voting into effect before the November 3 midterm election. The decision leaves in place a lower-court order blocking the U.S. Postal Service from implementing the new requirements this fall.

‘A victory for our democracy.’

That means California’s existing vote-by-mail system will continue for the 2026 election.

For California, where voting by mail is the primary way many people cast their ballots, the stakes were particularly high. About 80% of California voters cast their ballots by mail in the 2024 election.

California Attorney General Rob Bonta, who led a coalition of states challenging the Postal Service changes, welcomed the Supreme Court’s decision.

“After losing in the district and appellate courts, the Trump Administration has now lost at the U.S. Supreme Court,” Bonta said. “Today’s decision is a victory for our democracy and a powerful affirmation of the rule of law.”

“The stakes in this litigation could not have been higher,” Bonta continued. “Voting is the fundamental right from which all other rights flow, and all 50 states allow ballots to be cast by mail in some form.”

What was Trump trying to change?

The controversy began with an executive order issued by President Donald Trump in March that directed the federal government to make significant changes to the way mail-in and absentee ballots are handled.

The subsequent USPS rules would have required states and local election officials to redesign and reprint ballot envelopes, enroll millions of voters in a new USPS system and comply with new federal requirements. USPS would have been permitted to reject ballot mailings that did not meet the requirements.

For California, and much of the nation, the timing was a major concern.

Election officials were already preparing for an election only weeks away. Under the proposed system, California would have had to enroll roughly 23 million voters with new identification information before ballots could be mailed, according to court filings reported by the Los Angeles Times.

The states challenging the rules argued that implementing such sweeping changes so close to an election could create confusion, delays and the possibility that eligible voters would not receive their ballots.

The Trump administration argued that the changes were intended to strengthen election security and prevent fraud. The White House said the March executive order was designed to establish citizenship verification for federal elections and modernize mail-ballot procedures.

A question of who runs elections

At the heart of the legal battle was a fundamental question: Who has the authority to determine how elections are conducted?

Bonta and the coalition of states argued that states primarily administer elections, subject to federal laws enacted by Congress.

The Supreme Court’s Monday order did not fully resolve those constitutional questions. Instead, the justices declined the Trump administration’s request for emergency relief, leaving the lower court’s injunction blocking the USPS changes in place for the November election. Justice Brett Kavanaugh agreed that it was too late to impose the new rules for this year’s election, while Justices Samuel Alito and Clarence Thomas dissented.

The ruling provides certainty for the 2026 election, but it does not necessarily end the larger legal battle over how much authority the federal government has to regulate mail voting. The administration could pursue different rules for future elections.

California’s vote-by-mail system remains intact. For Pasadena voters, however, the practical message is considerably simpler. The vote-by-mail system they have used remains in place for November.

‘Now, let the people vote!’

California Secretary of State Shirley N. Weber put it plainly after the ruling:

“The ruling on mail-in ballots has been made. The uncertainty is behind us. Now, let the people vote!”

Weber said voters could cast their ballots “without uncertainty, without hesitation, and without fear that their voices will be questioned or their ballots rejected.”

Bonta also urged eligible voters to participate.

His office noted that California and several other states rely heavily on voting by mail, making the court fight about more than postal procedures. It was also about whether an entirely new federal system could be imposed on states in the final weeks before an election.

For Pasadena, where voters routinely use mail ballots as part of the electoral process, Monday night’s ruling means something quite tangible: the election can proceed under the rules voters already know.

After months of legal uncertainty, perhaps the most important word coming out of the Supreme Court this week is a simple one:

Vote.
