The U.S. Supreme Court on Monday, September 14, 2026, rejected an emergency request from the Trump administration to implement new restrictions on mail-in voting before the upcoming midterm elections. The ruling allows states to continue using existing procedures for distributing ballots, a process that historically accounts for approximately one-third of all American votes. The court's brief order did not provide an extensive legal rationale, though a majority indicated the administration's effort would likely be unsuccessful on legal grounds.
The administration’s proposal sought to require states to use standardized envelope designs and submit voter eligibility lists through a new federal online portal. Under the plan, the U.S. Postal Service would have been authorized to refuse delivery of mail-in ballots from states that did not comply with these regulations. Lower courts had previously blocked the plan, prompting the administration to appeal to the Supreme Court for immediate intervention as voting for the 2026 midterms had already begun.
Justices Samuel Alito and Clarence Thomas dissented from the decision, with Alito stating that the Postal Service likely holds the authority to regulate mail-in ballots as proposed. Justice Brett Kavanaugh concurred with the majority's decision to keep current rules in place for the midterms but suggested he might support the administration's position if the matter returns to the court in the future. Attorneys for voting rights groups and several states argued the president lacked the constitutional authority to change election rules so close to an election.
This decision affects voters and election officials across the United States who rely on mail-in systems. In states like Washington, Arizona, and Utah, where mail-in voting is a primary method of participation, the ruling prevents an overhaul of election procedures that officials said was impossible to complete in the final weeks before November. A whistleblower report submitted during the litigation warned that glitches in the administration’s proposed online portal could have resulted in ballots being discarded due to barcode errors.
For the individual voter, the ruling means that ballot delivery and return processes will remain unchanged. Residents in states such as Alabama, North Carolina, and Wisconsin, which began mailing ballots in the week prior to the ruling, will not have their current ballots invalidated or delivery interrupted. If the administration's plan had been enacted, the Postal Service could have stopped delivering ballots in non-compliant states, potentially forcing households to find alternative ways to vote or lose their ability to participate if their state lacked the infrastructure for a shift to in-person voting.
The ruling maintains state-level election administration during an active election cycle. While the court did not rule on the permanent legality of the administration's plan, the decision ensures that the 2026 midterm results will be determined under long-standing rules. Election officials including Republican Utah Lt. Gov. Deidre Henderson and Democratic secretaries of state from Washington and Arizona stated the decision provides stability to conduct the election. The administration has not yet announced if it will continue to pursue these changes for future election cycles.
