The US Supreme Court has rejected President Donald Trump’s plan to restrict voting by mail ahead of the November midterm elections. The justices upheld a federal judge’s order temporarily blocking the US Postal Service from implementing new postal ballot requirements.
The Legal Battle Over Postal Service Regulations
The dispute centers on an executive order signed by President Donald Trump in March, directing the US Postal Service to deliver ballots exclusively to voters listed on official citizen registries. Twenty-three states and Washington D.C. challenged the directive, arguing it infringed upon states’ constitutional rights to administer their own elections.
Here is why that matters for election administration: Boston-based Judge Indira Talwani issued an injunction on September 4, halting the mandate. Judge Talwani reasoned that executing sweeping postal modifications immediately before a national election threatened widespread voter disenfranchisement. A federal appeals court subsequently refused to stay Judge Talwani’s ruling, and another federal judge, Carl Nichols, delivered a parallel ruling against the administration’s plan.
Inside the Supreme Court’s Divided Decision
The high court’s action leaves the lower court injunction intact for now, though observers note the legal fight remains open. Justice Brett Kavanaugh voted to deny the immediate request to enforce the rules, writing in an opinion that applying the directive during the 2026 elections would be “arbitrary and capricious.” However, Justice Kavanaugh added that there was “at least a fair prospect that the final rule falls within the Postal Service’s statutory authority,” signaling potential future battles.
But there is a distinct ideological fracture on the bench. Justices Samuel Alito and Clarence Thomas dissented from the majority. The two conservative justices characterized the legal challenge against the administration’s order as a “Hail Mary pass,” emphasizing that the Postal Service holds broad authority to regulate the mail.
| Date / Court | Action Taken | Key Details |
|---|---|---|
| March | Executive Order | Directed USPS to transmit ballots only to individuals on state-specific lists. |
| September 4 | Federal District Court | Judge Indira Talwani issued an injunction blocking the USPS order. |
| September | US Supreme Court | Denied the Trump administration’s request to lift the injunction ahead of midterms. |
Operational Hurdles and Broader Electoral Context
Beyond the constitutional arguments, logistical realities heavily influenced the courts’ decisions. The postal workers’ union warned the judiciary that clerks could not be trained in time for the November contests. Meanwhile, a national security group raised alarms regarding the potential disruption of overseas military voting.
President Trump has consistently maintained that mail-in voting is susceptible to fraud and allows non-citizens to cast ballots, though critics note those claims remain unsubstantiated. This ruling marks a setback on postal ballots for the administration. In June, the Supreme Court rejected a separate push to block states from counting ballots postmarked by election day.
With mail-in ballots accounting for roughly 30 percent of total votes cast in the 2024 general election according to the US Election Assistance Commission, the integrity and accessibility of postal voting remain central to the outcome of the upcoming midterm elections.
