Judge Talwani blocks USPS mail ballot rule before midterms

A federal judge in Boston has temporarily blocked the US Postal Service from enforcing the rule it wrote to carry out President Trump's executive order on mail voting, ruling late on Thursday, August 27, that the states challenging it are likely to win and that many of them could not comply before the midterms even if they tried.

US District Judge Indira Talwani issued a temporary restraining order lasting 14 days, as NPR first reported. She has scheduled a hearing for September 3 on whether to convert it into a preliminary injunction, which would hold through the litigation rather than expiring on a clock.

The order is narrow in duration and broad in reach. It stops the Postal Service's Final Rule nationwide, restoring in substance a block Talwani had imposed earlier and that the Supreme Court removed on Monday, August 24, on procedural rather than substantive grounds.

The nine days that decide this

The dates in this case are not background. They are the case.

USA Times' comparison of the court's own schedule with the federal ballot-transmission deadline finds the restraining order lapses on September 10, nine days before the September 19 statutory deadline for states to send ballots to military and overseas voters. That deadline is not discretionary and not set by the Postal Service: the Uniformed and Overseas Citizens Absentee Voting Act requires states to transmit requested absentee ballots no later than 45 days before a federal election, and 45 days before November 3, 2026 is September 19.

If Talwani grants a preliminary injunction after the September 3 hearing, the gap closes and states print what they already have. If she does not, the rule becomes enforceable during the precise window in which ballots must physically be in the mail to service members abroad. That is what makes a 14-day order in late August consequential in a way a 14-day order in March would not be.

What the rule requires

Under the Postal Service's Final Rule, states and local election officials would have to submit their mail ballot envelopes and return envelopes to USPS and receive advance approval before the service would carry them. States would also have to upload lists of their mail voters to a Postal Service portal, and ballots would have to travel in envelopes carrying barcodes unique to each voter, which the administration says would support automated tracking and law enforcement inquiries.

Talwani quoted the practical consequence in her ruling: "Through the Final Rule, the USPS is refusing to send mail ballots to eligible voters unless States or local election officials submit their mail ballot envelopes and return envelopes and receive advance approval from the USPS without regard to impending deadlines for the November 3, 2026 election."

The states' filings set out what compliance would actually involve, and the judge adopted the list in her order: "Plaintiff States have neither time nor funds to design new mail ballots, seek approval of the new designs, order production of mail ballots, update their own election management systems, train election officials to use the USPS portal, and upload citizen data to the portal, all before the midterms."

What the Final Rule requires	What election officials told the court
Advance USPS approval of ballot and return envelope designs	New designs, then approval, then a print run, inside 54 days
Voter-specific barcodes on every mail ballot envelope	Millions of envelopes reprinted; vendors said the job could not be done in time
Upload of mail voter lists to a USPS portal	Portal untested at scale; officials questioned feasibility
Compliance regardless of election deadlines	The federal military and overseas deadline falls on September 19

The Justice Department argued in its filings that the regulatory change was "modest" and that the Postal Service had statutory authority to make it. Talwani wrote that the administration offered "no reply to Plaintiff States' assertion that compliance for the 2026 midterm elections will be impossible for many of them." An argument that is never answered is not a difficult one for a court to credit.

Two separate questions, easily confused

Monday's Supreme Court decision and Thursday's district court order are about different things, and the difference is the whole procedural story.

The Supreme Court, over the dissent of its three liberal justices, set aside Talwani's earlier June ruling because at the time the states filed suit the agencies had not yet issued their final implementation plan. The objection was to timing, not to the merits. The high court has not ruled on whether the executive order or the rule implementing it is lawful.

Talwani's new order answers the question the Supreme Court said was not yet ripe. The plan now exists, it has been published, and the states have sued over the thing itself. On that posture she found the challengers likely to succeed both on the constitutional claim and on the narrower administrative one, that the Postal Service lacked authority to issue the rule at all.

The second finding is the more portable of the two. A holding that an agency exceeded its statutory authority does not require a court to reach any constitutional question, and it travels through the appellate courts on ordinary administrative law rather than on election law. The most likely way this rule dies is not a ruling about voting rights but a ruling that the Postal Service is not an election regulator.

What happens next

It is not clear whether the administration will appeal the temporary restraining order immediately or wait for the preliminary injunction decision, which is the conventional route. The Justice Department did not respond to inquiries on Thursday.

Either path leads back toward the Supreme Court, which has now touched this dispute once without saying anything about whether the underlying order is lawful. The justices are unlikely to have the last word before September 19, which means the operative deadline in this case will arrive before the final ruling does. Election officials in the twenty-odd states that sued will spend the next three weeks preparing to mail ballots under rules that may or may not be in force on the day they mail them.
