Missouri residents who want to vote by mail cannot return their ballots in person but must use the postal system, a federal appeals court ruled Thursday.
The 8th Circuit Court of Appeals ruling upholds a state law that requires mail ballots be returned through the U.S. Postal Service.
The court stayed a district court ruling that would have allowed voters to return their mail ballots in person.
Mail-in ballots will need to be returned soon because they must be received by election officials by Election Day in order to be counted.
