Supreme Court Lets Trump Advance Mail-Ballot Rules, for Now

A procedural victory with unsettled consequences

The Supreme Court on Monday voted 6-3 to lift an injunction that had stopped federal agencies from carrying out parts of President Donald Trump’s March executive order on mail voting in 23 Democratic-led states and Washington, D.C.nbcnews +1 The unsigned order gives the administration room to proceed ahead of November’s midterms, but it does not decide whether the resulting policies are legal.npr +1

The majority concluded that the states sued too soon because the executive order itself had not harmed them. The justices stressed that future agency measures would not automatically be lawful, leaving states free to challenge finalized policies.cbsnews +1

Federal agencies can resume preparations

The order directs the Department of Homeland Security to compile state-by-state citizenship lists and tells the U.S. Postal Service to develop procedures for ballot mail. It also instructs the attorney general to prioritize cases involving officials accused of issuing ballots to ineligible voters.abcnews +1

USPS has finalized a rule requiring states to place unique barcodes on mail-ballot materials and upload voters’ names and addresses to a federal portal before ballots enter the mail stream. The agency says it will not determine eligibility, maintain voter rolls or count ballots, and the rule does not authorize it to refuse transmission based on whether a voter appears on a state list.abcnews +1

The immediate effect remains limited by another nationwide ruling issued August 11 in a separate case, which still blocks the Postal Service from following Trump’s directives. The administration signaled that it would seek to pause that order as well.npr California officials, meanwhile, said they plan a new lawsuit now that the postal rule is final.nbcnews +1

New litigation meets a shrinking calendar

The court’s liberal justices dissented. Justice Sonia Sotomayor said the decision postpones review without endorsing presidential authority over state-run elections, while Justice Ketanji Brown Jackson warned that it injects uncertainty into an election cycle already underway.npr +1

The White House called the ruling a victory for election security. Democratic state officials argue that the policy could force them to redirect staff, redesign envelopes and retrain election workers shortly before voting begins.cbsnews About 30% of U.S. voters and 80% of Californians voted by mail in 2024, underscoring the potential reach of any late procedural change.latimes

For voters, Monday’s action changes no eligibility rule by itself and does not ban mail ballots. Its practical importance depends on whether USPS can implement its system, whether the remaining injunction is lifted and how quickly states bring the next round of challenges.npr +1
