The Trump administration has asked the U.S. Supreme Court to permit enforcement of new federal mail-ballot requirements ahead of the November 2026 midterm elections.
In an emergency application filed September 3, the Justice Department challenged an order issued by U.S. District Judge Indira Talwani that temporarily prevents the U.S. Postal Service from implementing specified provisions of its finalized mail-ballot rule.
Judge Talwani issued the temporary restraining order on August 27 after voting-rights organizations challenged the completed USPS rule. The order remains effective for 14 days, through September 10, while the court considers a request for a longer preliminary injunction.
What Does the USPS Mail-Ballot Rule Require?
The USPS rule would require election officials to provide information about mail-ballot recipients and use agency-approved outbound and return envelopes carrying unique barcodes.
USPS could refuse to send certain ballots if the ballot mail did not satisfy the federal standards or if the recipient’s information did not appear on the submitted voter list.
The administration argues that the requirements fall within USPS’s authority to regulate the federal mail system and would help prevent election fraud.
The challengers contend that the rule interferes with state control over elections and could prevent eligible voters from receiving mail ballots. They also argue that election officials do not have enough time to redesign materials and update their systems before voting begins.
Judge Questions Readiness of USPS System
Judge Talwani held a hearing September 3 to consider whether the temporary order should be replaced by a longer preliminary injunction.
During the hearing, government attorneys could not definitively tell the court whether the electronic portal needed to administer the voter-data requirements was operational. The portal would be used by election officials to upload information concerning mail-ballot recipients.
The court is now considering whether the challenged provisions should remain blocked beyond September 10.
Administration Seeks Relief From Two Courts
The administration previously asked the U.S. Court of Appeals for the First Circuit to stay Judge Talwani’s order. It then submitted its emergency application to the Supreme Court without waiting for the First Circuit to rule.
The Supreme Court may request responses from the challengers, issue temporary administrative relief while considering the application or deny the request. Any emergency decision would concern whether the rule can be enforced while litigation continues, not necessarily whether the rule is ultimately lawful.
Supreme Court Previously Considered an Earlier Challenge
This is the second time the dispute over President Donald Trump’s mail-voting directive has reached the Supreme Court.
On August 24, the Court stayed an earlier injunction after concluding that the challenge had been brought before USPS finalized its implementing rule. Brownstone Law previously reported on the Supreme Court’s decision to stay that injunction.
Following that ruling, Judge Talwani lifted an earlier block on the administration’s mail-voting policy. Once USPS issued its final rule, new challenges were brought against the completed agency action, leading Judge Talwani to temporarily block key provisions on August 27.
What Happens Next?
The Supreme Court must decide whether to allow the disputed USPS requirements to take effect while the case continues.
Proceedings also remain pending in the First Circuit and the federal district court. Unless another court changes the order, the challenged provisions remain temporarily blocked through September 10 while Judge Talwani considers longer-lasting relief.
