Supreme Court's 7-2 order keeps the USPS citizenship-verification rule out of the 2026 midterms

Kavanaugh gave a reason election administrators can plan against. He wrote that there was "a fair prospect" the final USPS regulation would sit within the government's legal authority ^[3]. Then he refused the stay on the calendar. "But applying the rule in the 2026 elections would be arbitrary and capricious and in violation of the Administrative Procedures Act because state and local election officials do not have sufficient time to reasonably implement the rule before the elections," he wrote ^[4].

The majority's stated reason is narrower. Jackson wrote that the administration "is unlikely to succeed on the merits of its challenge to the District Court's preliminary injunction" and had failed to articulate a valid reason for emergency relief ^[2]. Which of those two readings the lower courts apply decides whether the finalized rule comes back for a later cycle intact.

The order would have had the Postal Service verify voter citizenship and validate ballot materials. It would also have put a barcode tracking system on mail ballot envelopes, and had the Service work from "State Citizenship Lists" compiled by the Department of Homeland Security ^[5]. States and voting rights organizations challenged it on the ground that the executive branch has no constitutional authority to dictate how they maintain their voter rolls ^[6]. The White House argued that Article II gives the federal government "an unavoidable duty" to maintain confidence in election outcomes by preventing violations of criminal law, including noncitizen voting ^[7].

The administration kept finalizing the USPS rule while it litigated ^[9]. A whistleblower complaint alleged that a "rushed" White House and USPS effort to install three new restrictive IT systems for citizenship verification could deny thousands of mail-in ballots. The denials would come if the federal government disagrees with states on a voter's or a ballot's eligibility ^[10]. Lower courts had already blocked the order from taking effect before November, and CyberScoop described the Supreme Court petition as the administration's best and final hope for judicial relief ^[8].

Alito's dissent, signed by Thomas, ran more than seven pages ^[12] against less than half a page for the Jackson and Kavanaugh rationale, roughly fourteen times the length ^[11][13]. He would have granted the stay and let the order run in 2026, held that the states and organizations suing lacked standing, and called their concern about educating voters "abstract social interests" ^[14].

David Becker, executive director of the nonprofit Center for Election Integrity and Research, spoke to reporters before the ruling. He doubted members of the majority "want to own the chaos that would ensure" as the USPS, states and voters absorbed changes months before an election. Many states had begun sending out ballots that do not comply with the proposed rules ^[15]. On the court's record in election administration cases, Becker said: "When they consider issues related to the administration of elections, the casting and counting of ballots, they have sided with the states every time" ^[16].
