The Supreme Court cleared the way on August 24 for President Trump’s mail-in voting restrictions to proceed, lifting a lower court’s block and handing the administration a preliminary victory ahead of the November midterm elections. In a 6-3 emergency order, the Court sided with the Trump administration’s appeal in Trump v. California, allowing key provisions of an executive order signed in March to move forward while legal challenges continue.
Trump’s March 31 executive order, titled “Ensuring Citizenship Verification and Integrity in Federal Elections,” directs the U.S. Postal Service and Department of Homeland Security to verify voter citizenship and restrict mail-in ballots to people on federal lists of eligible voters. The order also requires states to update ballot envelopes with secure identifiers such as barcodes.
A federal judge in Massachusetts had blocked major portions of the order on August 11, finding it likely unconstitutional and likely to disenfranchise voters. The Trump administration appealed to the Supreme Court, which granted a stay of that injunction, allowing the administration to proceed while the underlying legal case continues.
In a sharply written dissent, Justice Ketanji Brown Jackson warned that the Supreme Court’s decision “needlessly injects chaos and uncertainty into the upcoming midterm elections.” Jackson argued that lifting the block would force states to litigate the restrictions closer to Election Day, compounding administrative confusion. She also contended that the President lacks legal authority to direct the Postal Service to restrict ballot delivery based on citizenship verification lists.
The Supreme Court’s order was not a final ruling on the merits; it allowed the administration to enforce the order while litigation proceeds. However, the legal landscape shifted again just days later. On August 27, a federal judge in Boston issued a temporary restraining order blocking the Postal Service from enforcing the new mail-ballot rules. A second federal court then lifted that block on August 26, creating a patchwork of conflicting orders.
The ongoing litigation reflects a broader conflict between federal executive authority and state election administration. States have historically controlled mail-in voting procedures, but Trump’s order asserts federal control through the Postal Service. The Brennan Center for Justice and other voting rights organizations have argued that the order threatens to create confusion among election officials and delay ballot delivery to eligible voters, particularly seniors and military members who rely on mail voting.
The Supreme Court’s June 2026 ruling on mail-in ballots showed the Court previously sided with states on voting access. In that decision, the Court upheld counting timely mailed ballots that arrive after Election Day if postmarked by Election Day, rejecting arguments to restrict mail voting. The August 24 order represents a marked shift, with the Court allowing restrictions to move forward despite lower court findings that they likely violate federal law.
As of late August, the order remains in legal limbo, with federal judges continuing to issue temporary blocks while the case works through the courts. The Trump administration has appealed the most recent federal court blocks, keeping the matter before appellate judges with the midterm elections less than three months away.
