Federal Court Blocks USPS Mail-In Voting Restrictions Again as November Elections Near

On Friday, September 4, 2026, U.S. District Judge Indira Talwani issued a preliminary injunction blocking the U.S. Postal Service (USPS) from implementing sweeping new restrictions on mail-in voting. The ruling represents a critical setback for the Trump administration's efforts to restrict mail-in voting, coming less than 70 days before the November 2026 midterms and just as states are beginning to send out mail ballots.

The Postal Service's rule, which derives from an executive order President Trump signed in March, would require states to provide a verified list of registered voters to the federal government.¹ Under the rule, the USPS would decline to deliver mail-in ballots to any voters not included on those lists.

In late August, the U.S. Supreme Court lifted an earlier injunction issued by Judge Talwani, ruling that the challenge was premature because the USPS had not yet finalized its rule. However, once the rule was finalized, voting rights groups and state attorneys general immediately filed a new lawsuit.

In her September 4 decision granting the preliminary injunction, Judge Talwani found that the rule was likely unlawful and unconstitutional. She emphasized the immediate threat of mass disenfranchisement:

"The court finds, on one side, that immediate implementation of the Final Rule issued less than seventy days before the November 2026 election threatens disenfranchisement of millions of United States citizens who seek to vote by mail," while "on the other side, that the record includes no evidence relating to fraudulent mail voting to support the rushed implementation of the Final Rule."

The Trump administration has already filed an emergency appeal to the Supreme Court, seeking to override Talwani's block. The legal battle highlights the administration's persistent efforts to federalize election mechanics and restrict mail-in voting, contrasted against fierce pushback from state officials and the federal judiciary.
