The U.S. Supreme Court, in a 5-4 decision, has upheld state laws that allow for the counting of late-arriving mail-in ballots, provided they were postmarked by Election Day. The ruling affirms existing state election regulations that accommodate ballots arriving after the official deadline.

This decision impacts how certain mail-in votes will be considered in elections where such laws are in place. The court's majority supported the continued validity of these ballots, emphasizing the postmark as the key indicator of timely submission.
