The Supreme Court on Monday allowed the Trump administration to move forward with parts of an executive order that would significantly change how mail-in ballots are processed, while leaving the underlying legal dispute unresolved. The 6-3 decision concerned a lower-court injunction covering 23 states and the District of Columbia, with the conservative majority finding that the states had challenged the administration before demonstrating sufficient concrete harm. A separate nationwide injunction continues to block at least part of the order, meaning the ruling does not immediately put the full policy into effect.

Trump signed the executive order in March as part of a broader effort to increase federal oversight of election procedures. The order directs the creation of lists of voters eligible to receive federal election ballots and calls for the U.S. Postal Service to deliver mail ballots only to voters appearing on those lists. It also calls for new requirements for ballot envelopes and other changes to postal procedures. Democratic-led states challenged the order, arguing that election administration is largely controlled by states and that the federal government lacks authority to impose the changes through executive action. The Supreme Court's ruling addressed the timing and legal standing of the states' challenge rather than the ultimate legality of Trump's order.
