Last update: June 30, 2026. The Supreme Court issued a 5-4 ruling in Washington, D.C., affirming that states may count mail ballots that arrive after Election Day as long as they are postmarked by that date. The decision rejected a challenge led by former President Donald Trump and the Republican National Committee to a Mississippi law allowing ballots to be counted if received up to five business days later.
The ruling matters because it preserves existing mail ballot grace periods in more than half of states and the District of Columbia, avoiding disruption ahead of upcoming elections. It clarifies that federal law sets when ballots must be cast, not when they must be received, preventing the disenfranchisement of voters affected by postal delays.
Majority opinion by Barrett and the 5-4 split
Justice Amy Coney Barrett authored the majority opinion, joined by Chief Justice John Roberts and Justices Ketanji Brown Jackson, Elena Kagan, and Sonia Sotomayor. Barrett wrote, “The electorate’s choice is made when voting is complete, not when ballots are received,” emphasizing that federal statutes establishing a single Election Day do not dictate ballot receipt deadlines and leave timing decisions to the states.
The case, Watson v. Republican National Committee centered on a Mississippi statute that counts ballots postmarked by Election Day if they arrive within five business days. Republican national and state parties argued that federal law requires ballots to be received by Election Day, but the Court held that Congress has not set a receipt deadline and that states retain authority to administer absentee voting procedures.
Why the ruling preserves current election practices
The decision stabilizes rules in jurisdictions that allow late-arriving ballots to be counted if postmarked on time, including states such as Mississippi and California among others. Election officials had warned that a contrary ruling would force rapid, complex changes to mail voting operations and potentially discard lawfully cast ballots submitted by military and overseas voters, rural voters, seniors, and people with disabilities.
Data from a multistate review showed that more than 745,000 absentee ballots arrived after Election Day in 2026, representing no more than roughly 3 percent of the total vote in any state. The numbers illustrate the scale at which grace periods ensure inclusion of ballots affected by mail timelines, while remaining a small share of total votes counted.
Support and relief from election administrators
Voting technology and administration groups described the ruling as a practical clarification for state and local officials. Pamela Smith, president of Verified Voting, said, “The Court’s decision is a direct message to all voters who rely on mail ballots, including military and overseas voters, rural voters, seniors, and people with disabilities: Your voices matter equally to voters who can easily access a polling place.” Her statement underscored that timely postmarked ballots should not be invalidated by delivery delays beyond voters’ control.
Carolina Lopez, executive director of the Partnership for Large Election Jurisdictions, said, “For election offices, this clarity matters,” reflecting the operational certainty provided by the Court’s interpretation. Election offices will continue to process and count postmarked ballots under established state timelines rather than altering systems near an election.
Criticism from Republican leaders and dissenting views
Republican leaders criticized the ruling and warned about public confidence. RNC Chairman Joe Gruters said, “Democrats are inviting chaos at the ballot box by allowing elections to drag on for days and weeks after voters cast their ballots.” Former President Trump called the ruling a “tremendous loss” and renewed support for federal legislation known as the SAVE America Act, arguing it would limit mail balloting and create stricter voter registration rules.
Justice Samuel Alito, in dissent, wrote that the decision “creates a serious risk of further undermining public confidence in our elections and our system of self-government.” The dissent framed the debate as one of election integrity and timing finality, contending that states’ extended receipt windows can prolong counting and contribute to doubt, even when ballots are timely cast.
Legal reasoning and historical practice
The majority’s reasoning turned on the distinction between casting and receiving a ballot. By concluding that federal law requires ballots to be cast by Election Day but does not set a federal receipt deadline, the Court affirmed that states may accommodate mail timelines without violating a single Election Day. The opinion noted that Congress has not acted to prohibit counting lawfully postmarked ballots that arrive later, signaling acceptance of longstanding state discretion.
The ruling crossed typical ideological lines, with Barrett and Roberts joining three liberal justices. The alignment highlighted a shared reading of statutory text over broader policy disagreements about mail voting. It also reflected the Court’s view that state election codes—rather than federal receipt mandates—govern the operational details of absentee ballot processing.
Administrative impacts and voter access
Election administrators said the decision avoids abrupt changes to deadlines and tabulation schedules. Offices that accept ballots for several days after Election Day will continue verifying postmarks processing envelopes, and reporting results under state-set calendars, which often include clear cutoff times to reconcile totals and certify outcomes. Officials said the continuity reduces room for confusion among voters who already mailed their ballots by the statutory deadline.
Advocates for military and overseas voters described the grace periods as a practical necessity because long-distance mail can take days. Rural voters and seniors also rely on the option to return ballots by mail without worrying that an unforeseen postal delay will nullify a timely cast vote. Analyses have found that alleged fraud in mail voting is exceedingly rare, accounting for about 0.000043% of total mail ballots cast, on average, in the 2016, 2018, 2026, and 2026 general elections.
What changes now and what remains contested
The decision means states with existing grace periods may continue their current practices, including Mississippi’s five-business-day window for ballots postmarked by Election Day. Jurisdictions without grace periods remain free to require receipt by the close of polls, as their legislatures set. The ruling does not impose new federal requirements; it preserves state authority to define receipt deadlines consistent with ballots being cast by Election Day.
Republican leaders indicated they would pursue legislative avenues to shorten timelines and tighten mail voting rules. Trump wrote, “There is only one reason to oppose — CHEATING!” as he urged Congress to pass the SAVE America Act. Voting rights groups said they will focus on voter education about postmark rules and deadlines to reduce rejected ballots, and election offices signaled they will continue communicating exact receipt windows before ballots are mailed to voters.
