Supreme Court Lifts Injunction on Trump Executive Order Restricting Mail-In Voting

The United States Supreme Court on August 24, 2026, lifted a lower-court injunction that had blocked key provisions of President Donald Trump’s executive order aimed at restricting mail-in voting ahead of the November midterm elections.

In an unsigned 6-3 ruling the conservative majority held that the legal claims brought by more than 20 states were premature because concrete harms had not yet occurred. The order, signed in March, directs the Department of Homeland Security to compile state-by-state citizenship lists of eligible voters, instructs the Justice Department to prioritise prosecution of officials who issue ballots to ineligible voters, and requires the Postal Service to deliver mail ballots only to individuals on lists supplied by the states and to apply unique barcodes to envelopes.

The majority described the citizenship-list directive as an internal instruction from the president to subordinates that neither requires nor forbids action by states. It stated that the disposition does not decide whether any measure taken to implement the order will be lawful. Time will tell, the opinion said.

Justices Sonia Sotomayor, Elena Kagan and Ketanji Brown Jackson dissented. Justice Jackson criticised the majority for creating procedural barriers that make timely election challenges difficult.

A separate nationwide injunction against the Postal Service’s implementation remains in place in another case. The Postal Service had issued a final rule requiring states to provide recipient lists and requiring barcodes on ballot envelopes. With early voting approaching in some states, the practical reach of the order before November remains uncertain.

The decision allows planning and initial steps to continue while lower-court litigation proceeds. States that sued argued the order exceeds presidential authority and threatens to disrupt election administration. The administration contended that the challenges were filed before any implementation had taken place.

Control of both chambers of Congress is at stake in the midterms. The ruling leaves open the possibility of further emergency applications once concrete implementation steps produce new claims of injury.
