A federal judge temporarily blocked postal officials from enforcing new ballot-mail restrictions for federal elections through November 3, 2026. The ruling matters because it prevents the Postal Service from refusing covered mail-in or absentee ballots under the preliminary injunction.
Key Facts
- Federal court: Judge Indira Talwani granted the organizational plaintiffs a preliminary injunction on August 11, 2026.
- Temporary relief: The injunction covers Section 3 of Executive Order 14399 for the November 3 election and any earlier federal election.
- Limited scope: Postal officials may still provide nonbinding guidance about ballot-mail envelopes.
What the judge ordered
A preliminary injunction is a temporary court order issued before a case receives a final decision. It does not permanently invalidate the executive order or decide every claim in the lawsuit.
The injunction binds USPS, its Board of Governors and the postal officials named in the order. President Donald Trump is a defendant, but the August 11 injunction does not run against him personally.
The postal defendants may not implement, enforce or give effect to Section 3 for the covered elections. That restriction includes refusing to transmit mail-in or absentee ballots under the section.
The defendants also may not begin or complete the specified Section 3 rulemaking for those elections. The ruling expressly allows nonbinding USPS guidance about ballot-mail envelope design.
The organizational plaintiffs must post a nominal $100 bond by August 18. The preliminary ruling is not a final judgment on Section 3.
What Section 3 proposed
President Trump issued Executive Order 14399 on March 31, 2026. Section 3 directed the postmaster general to begin ballot-mail rulemaking within 60 days.
The section called for official markings, automation-compatible envelopes and unique Intelligent Mail barcodes. It also directed USPS not to transmit certain ballots unless voters appeared on state-specific participation lists.
The executive order required a final rule within 120 days. Its general provisions said implementation must remain consistent with applicable law.
USPS published a proposed rule on June 2 and accepted comments through July 2. The proposal described envelope standards, barcodes, participation lists and a federal ballot-mail portal.
The proposal said states would control who appeared on their participation lists. It also said USPS would not decide whether a person should appear on a state’s list.
The June notice was a proposal, not a final regulation. The injunction bars the specified rulemaking for elections on or before November 3, while leaving nonbinding envelope guidance available.
Why the court granted temporary relief
Judge Talwani found the plaintiffs likely to succeed on their separation-of-powers and ultra-vires theories. An ultra-vires claim alleges that an official acted beyond authority granted by law.
This was a preliminary assessment rather than a final merits holding. The court also found that the plaintiffs faced irreparable harm without temporary relief.
The plaintiffs include eight voting and civic organizations whose members use mail voting. They argued that Section 3 exceeded presidential authority and threatened access to mailed ballots.
Federal defendants opposed the renewed motion and argued that the president had authority to direct executive-branch subordinates. They also argued that the dispute was premature before final agency action.
Twelve intervening states separately opposed preliminary relief. Their arguments included challenges to standing and assertions that the claims were unripe until USPS issued a final rule.
The court heard arguments on August 7 and rejected those positions for purposes of temporary relief. That decision does not prevent the defendants or intervening states from continuing to contest the claims.
What the order does not decide
The order does not block the entire executive order. It addresses Section 3 and the named postal defendants for federal elections through November 3, 2026.
It also does not resolve the Section 3 challenge for later elections. Earlier rulings dismissed later-election claims without prejudice on ripeness grounds.
The case concerns the limits of presidential and agency authority, a recurring subject in constitutional disputes over government power. For now, the practical result is that the challenged postal restrictions cannot govern the covered elections under the preliminary injunction.
