Federal judge vacates injunction blocking USPS mail-ballot rule

Overview

Updated Yesterday

Judge Indira Talwani issued a preliminary injunction September 4 blocking the U.S. Postal Service's new mail-ballot rule for the November 3 midterms. The First Circuit upheld that block September 10, and the Justice Department is now pressing its emergency appeal at the Supreme Court.

The rule comes from President Trump's March executive order. It would require states to share voter lists with USPS and use barcoded envelopes; noncompliant ballots would not be delivered. North Carolina began mailing ballots September 4, and the Supreme Court has not yet ruled on the administration's stay application.

Why it matters

States must submit voter data and adopt federal barcoded envelopes within weeks, or the Postal Service will not deliver their mail ballots.

Scenarios

New injunction blocks rule before November 3

Possible Resolves by Nov 2, 2026

Discussed by: Reuters, NBC News

The states' new lawsuit, filed the same day the injunction was vacated, argues the now-final rule exceeds USPS statutory authority and intrudes on state election administration. Talwani explicitly left open the possibility of a new preliminary injunction. She earlier ruled the USPS violated her original order by publishing the rule, which could weigh against the government.

Rule takes effect for November election, legal fight continues

Likely Resolves by Nov 4, 2026

Discussed by: CNBC, Associated Press

With no court order currently blocking the rule, USPS can apply it to the November election. The agency previously said it would not implement the rule for 2026 unless both injunctions were lifted. That condition is now met. Election officials in states have already designed envelopes and prepared ballots, and the rule's verification requirements take effect immediately.

Court strikes down rule on the merits

Uncertain Resolves by Dec 15, 2026

Discussed by: Democracy Docket, Election Law Blog

After the election, the case proceeds to full judicial review. Challengers argue the rule requires states to hand over voter lists in ways that exceed USPS statutory authority and conflict with state control over election administration. A merits ruling against the rule would not undo the midterms but would set precedent blocking similar future rules.

Supreme Court lets preliminary injunction stand through midterms

Uncertain Resolves by Nov 3, 2026

Discussed by: Democracy Docket, CBS News

The Court could deny the administration's emergency application, keeping the rule blocked for the November 3 election. The challengers' response is due September 8; the Court could act any time after.

Supreme Court stays preliminary injunction, USPS rule takes effect for November

Possible Resolves by Sep 15, 2026

Discussed by: SCOTUSblog, Democracy Docket

The administration's renewed application (No. 26A305) asks the Supreme Court to stay Talwani's preliminary injunction. A stay would let the Postal Service enforce its envelope standards, portal registration, and verification requirements for the November 3 election. The Court's August 24 ruling in the related case favored the government on standing and ripeness, but this challenge targets the final rule directly.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

December 2000

Bush v. Gore (2000)

The Supreme Court intervened in Florida's vote recount in December 2000, effectively deciding the presidential election. The Court's 5-4 ruling halted the recount and cited the time pressure of the approaching certification deadline.

Then

The recount stopped, and George W. Bush won Florida's electoral votes by 537 ballots.

Now

Showed courts will act quickly on election procedures under extreme time pressure, sometimes without full merits review.

Why this matters now

The current case follows a similar pattern: emergency applications, stays, and time pressure weeks before an election. The Supreme Court's August 24 stay was per curiam, decided without full briefing.

July-October 2020

DeJoy-era USPS changes (2020)

Postmaster General Louis DeJoy implemented operational changes in summer 2020 that slowed mail delivery. States sued, and a federal judge ordered USPS to reverse some changes before the November 2020 election, which saw record mail-in voting during COVID.

Then

Operational changes were reversed or paused before the 2020 election.

Now

Established that courts will scrutinize USPS operational changes affecting mail ballots near elections.

Why this matters now

The same agency, USPS, is again changing mail-ballot handling under a new rule, and courts are again being asked to intervene close to an election.

April-November 2020

Trump campaign mail-voting lawsuits (2020)

Trump's campaign and allies sued Nevada, Pennsylvania, and other states over mail-ballot rules, arguing they invited fraud. Courts mostly rejected the suits, and the Biden administration later argued the litigation had no basis.

Then

Most challenges failed; mail voting expanded significantly in the 2020 election.

Now

The current executive order is a different approach to the same goal: tightening mail-ballot rules through executive action and agency rulemaking rather than litigation.

Why this matters now

The executive order and USPS final rule represent a shift from litigating against state mail-ballot rules to imposing federal requirements directly through agency action.
