The Supreme Court mail ballot ruling gives states room to count certain mailed ballots that arrive after Election Day. The 5-4 decision, issued June 29, upheld a Mississippi law covering ballots postmarked by Election Day and received up to five business days later.
Supreme Court Mail Ballot Ruling Centers on State Deadlines
The case, Watson v. Republican National Committee, focused on whether federal Election Day laws require mailed ballots to arrive by Election Day.
Justice Amy Coney Barrett wrote the majority opinion. Chief Justice John Roberts and the court’s three liberal justices joined her.
The court said federal law sets the deadline for voters to cast ballots. However, it does not set one national deadline for when mailed ballots must be received.
Mississippi’s law allows certain absentee ballots to count if they are postmarked by Election Day and arrive within five business days. The court said that rule does not conflict with federal law.
Why the Ballot Case Matters
The Republican National Committee, the Mississippi Republican Party and others challenged the law. They argued that counting ballots after Election Day violated federal statutes.
A federal appeals court had sided with the challengers. The Supreme Court reversed that decision.
The ruling matters beyond Mississippi. According to the National Conference of State Legislatures, several states allow at least some mail ballots to arrive after Election Day if voters mailed them on time.
The decision does not require every state to accept late-arriving ballots. Instead, it allows states to set their own receipt deadlines, as long as voters cast the ballots by Election Day.
What the Court Said
The majority said the key act in an election is the voter’s choice. In mail voting, that choice happens when the voter casts the ballot.
The court also pointed to federal laws for military and overseas voters. Those laws often refer to state deadlines for receiving ballots.
Justice Samuel Alito wrote the main dissent. He argued that federal Election Day laws should require ballots to arrive by Election Day.
The dissent warned that longer receipt windows could raise concerns about public confidence in elections. The majority said those policy arguments should go to lawmakers, not courts.
What It Means for Texas Voters
The decision does not change who can vote by mail in Texas. Texas limits mail voting to voters who meet specific eligibility rules, including voters age 65 or older, voters with disabilities, certain voters outside their county, eligible jailed voters and voters expecting to give birth near Election Day.
Texas also has its own ballot return rules. State guidance says a domestic mail ballot with a valid postmark or delivery receipt showing it was submitted by 7 p.m. on Election Day must arrive by 5 p.m. the next business day.
That means Texas voters should still follow state and county election deadlines closely. A postmark alone may not be enough if the ballot arrives after the state deadline.
Election Officials Prepare for 2026 Voting
The ruling arrives ahead of the 2026 midterm elections. It gives election officials clearer guidance in states with postmark-based mail ballot rules.
For voters, the safest option remains simple. Mail ballots early, track them when possible and check county election guidance before deadlines.
The Supreme Court mail ballot ruling keeps state-level ballot deadlines in place for now. Texas voters should confirm their local rules before every election.
