Washington, 30 June 2026
The U.S. Supreme Court ruled on Monday that states may continue to count mail-in ballots that arrive at election authorities after Election Day, as long as they were postmarked by Election Day.
The justices thereby overturned a ruling by an appeals court that had declared a corresponding provision in the state of Mississippi to be inconsistent with federal law. The majority reasoned that what matters is that the vote be cast no later than Election Day. While federal laws set Election Day for federal elections, they do not require that mail-in ballots be received by authorities by that date.
Background: Lawsuit Against Mississippi Rule
The background to the case was a lawsuit by Republicans against Mississippi's mail-in voting law. The state allows absentee ballots from, among others, persons aged 65 and over and people with disabilities; under state law, mail-in ballots may be received up to five days after Election Day, provided the envelope was postmarked no later than Election Day. The law is intended to account for the unreliability of the U.S. Postal Service, according to the state.
