Judge Halts Trump Mail-Ballot Rule for Two Weeks

Emergency relief, not a final ruling

A federal judge blocked the U.S. Postal Service late Thursday from putting key parts of its new mail-ballot rule into effect for the Nov. 3 midterms — reversing, within about 36 hours, a legal picture in which nothing stood in the rule's way.

U.S. District Judge Indira Talwani granted a temporary restraining order staying USPS from implementing certain sections of its final rule, "Ballot Mail for Federal Elections," 91 Fed. Reg. 54966 (Aug. 26, 2026), to be codified at 39 C.F.R. pt. 111. The Frank read the order itself: an 11-page memorandum captioned "Memorandum and Order Granting in Part Plaintiffs' Motions for a Temporary Restraining Order," dated Aug. 27, 2026, docketed as Document 31 in State of California v. United States Postal Service, No. 1:26-cv-13917-IT (D. Mass.), and joined for briefing with League of Women Voters of Massachusetts v. Trump, No. 1:26-cv-11549-IT.

Two things that order is not. It is not a decision that the rule is unlawful — a temporary restraining order, Talwani wrote, quoting First Circuit precedent, is "a provisional remedy imposed to maintain the status quo until a full review of the facts and legal arguments is available," and an "extraordinary and drastic remedy" that is "never awarded as of right." And it is not total: the order grants the plaintiffs' motions only in part, and stays "certain sections" of the rule rather than all of it. The Frank could not determine from the portion of the order it reviewed which requests were refused.

What is blocked, and for how long

Democracy Docket, which covers election litigation, reports the restraining order runs 14 days and bars USPS from enforcing key portions of the rule for elections on or before Nov. 3, naming the mandatory ballot-envelope standards, return-envelope standards, USPS portal registration, voter-enrollment requirements and ballot-mail rejection rules. The Hill, which posted at 11:19 p.m. ET Thursday, put it as a block of "at least another two weeks." The Washington Post described the order as halting parts of the effort that would bar USPS from delivering mail-in ballots.

The order lays out what compliance would have required of a state: ballot and return envelopes meeting USPS design standards, those designs submitted to USPS for approval, and then each voter's information entered into a USPS-run electronic portal. Talwani noted the rule sets no deadline for USPS to approve envelope designs while barring officials from uploading voter data until approval comes — and that where a state fails to get design approval, upload the data, or apply unique intelligent mail barcodes, "the USPS will not mail ballots to voters."

The judge's reasoning

Talwani found the challengers likely to succeed on claims that USPS lacked the authority to issue the rule, that it unconstitutionally imposes new requirements on states, and that it unlawfully blocks noncompliant state and local officials from using the mail to send ballots, according to Democracy Docket's account of the ruling. She addressed the jurisdictional problem the Supreme Court identified three days earlier directly: "now that the USPS has published the Final Rule, Plaintiffs' challenges are ripe."

On harm, Democracy Docket reports she found many states have already ordered mail ballots, some must send ballots to eligible voters as early as next week, and election officials lack the time and money to redesign envelopes, obtain USPS approval, update systems, train staff and upload voter data before the midterms. She also wrote that "the record continues to lack any evidence regarding fraudulent absentee or mail-in voting," and weighed USPS's interest in addressing what she called an "unsubstantiated problem" against the risk of widespread disenfranchisement.

Who brought it

The order names two sets of plaintiffs. The states: Arizona, California, Colorado, Connecticut, Delaware, the District of Columbia, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New Jersey, New Mexico, New York, North Carolina, Oregon, Rhode Island, Vermont, Virginia, Washington and Wisconsin, plus Gov. Josh Shapiro in his official capacity for Pennsylvania. They sued USPS, the postmaster general, the deputy postmaster general and the chair and members of the USPS Board of Governors. A group of Republican-led states, listed in the caption as State of Missouri et al., has intervened as defendants.

Talwani also quoted the government's own earlier assurances back at it. Two weeks before the rule issued, she wrote, defense counsel told the court that once a final rule was implemented and affected a voter, "they certainly have standing to challenge that final rule," and that "it would only take a very short amount of time for a temporary restraining order or a preliminary injunction to issue." Two days before this ruling, in asking her to vacate her earlier injunction, the government argued the plaintiffs could "simply amend their complaint." The government then argued the plaintiffs were too late. Talwani's answer: "the question is not when appellate review will be completed."
