The United States Supreme Court blocked the Trump administration’s plan to overhaul mail-in voting rules for the 2026 midterm elections, ruling that implementing sweeping changes just weeks before the vote would create unacceptable chaos. According to reporting from Il Fatto Quotidiano, ANSA, Corriere della Sera, and Il Sole 24 ORE, the justices rejected an emergency request from the federal government on September 14, leaving a lower court injunction in place.
The high court issued a concise one-paragraph order stating that the federal government was unlikely to prevail on the merits of the case. While the order did not specify the exact vote breakdown, the request was rejected by a 7-to-2 margin, with conservative justices Samuel Alito and Clarence Thomas dissenting. The decision deals a setback to President Donald Trump, who has long argued without presenting evidence that mail-in voting is vulnerable to widespread fraud.
The Executive Order and Postal Service Mandates
The administration’s contested plan originated from an executive order signed by Trump at the end of March. The subsequent United States Postal Service guidelines required local authorities to utilize federally approved envelopes featuring unique barcodes assigned to individual voters.

The rules also mandated that election offices transmit voter rolls through a new federal online portal, and authorized the postal service to withhold non-compliant ballots. Democratic-led states, civil rights organizations, and even seven Republican-led states challenged the initiative, warning that altering procedures mid-election cycle would cause severe delays, sorting errors, and misplaced votes.
Timing Outweighs Administration Authority
The deciding factor for the majority of the court was not the abstract legal authority of the administration, but the timing of the intervention. State officials and local election administrators lacked the necessary time to implement the complex new procedures before ballots were scheduled to be cast.

Conservative Justice Brett Kavanaugh wrote in a separate opinion that while the United States Postal Service might possess some statutory authority under federal law to regulate ballot envelopes, applying those rules so close to an election would be arbitrary and capricious.
Alito Dissent and Future Legal Battles
In his dissent, Justice Samuel Alito argued that the federal government demonstrated a strong interest in enforcing stricter controls over mail-in ballots to ensure electoral security. Alito acknowledged the practical difficulties raised by local officials, but maintained they did not outweigh the administration’s regulatory objectives.
The Supreme Court had previously allowed the preparation of the plan to proceed on August 24 despite dissenting votes from the court’s three liberal justices, but the latest ruling halts its application for November. Although the immediate restrictions will not affect the upcoming midterm elections, the underlying debate over mail-in voting security remains active. The months of litigation have amplified scrutiny around postal ballots, setting the stage for continued political and legal clashes after the 2026 votes are tallied.
