Supreme Court Decision on Late-Arriving Mail-In Ballots Grants Relief to 18 States

The US Supreme Court ruled in a 5-4 decision that states may count mail-in ballots arriving after Election Day if postmarked by that date. This ruling affirms a Mississippi law allowing a five-day grace period, as Justice Barrett noted federal law does not mandate receipt by Election Day. While President Trump criticized the decision for allegedly undermining election integrity, the ruling grants relief to 18 states and represents a setback for his efforts to regulate elections.
