The U.S. Supreme Court ruled that states may count mail-in ballots postmarked by Election Day even if they arrive after the deadline [1, 2].
This decision preserves the ability of various state governments to determine their own ballot receipt windows, potentially influencing the final tallies in closely contested elections.
The court issued the ruling on Monday, June 24, 2026, in Washington, D.C. [2, 4]. The decision came after the court rejected a legal challenge brought by the Republican National Committee [1, 2].
The Republican National Committee argued that counting ballots that arrive after Election Day violated the Constitution. However, the court found that state rules allowing such ballots to be counted are permissible [1, 5].
Legal experts said the ruling could affect voting deadlines in dozens of states [2], though some reports specify the impact reaches more than a dozen states [1]. The court's decision ensures that voters who mail their ballots on or before Election Day are not disenfranchised by postal delays, a recurring point of contention in recent election cycles.
Because the ruling upholds the authority of individual states, the specific deadlines for ballot arrival will continue to vary across the country. This maintains the current patchwork of election laws rather than imposing a single federal standard for mail-in voting receipt.
“The U.S. Supreme Court ruled that states may count mail-in ballots postmarked by Election Day even if they arrive after the deadline.”
This ruling reinforces the principle of state-led election administration by denying a federal mandate for strict arrival deadlines. By allowing postmarked ballots to be counted after Election Day, the Court reduces the risk that postal inefficiency determines election outcomes, though it also means that final results in some states may take longer to certify.
