A federal judge on Tuesday rejected an argument that requiring voters to provide their own stamps for mail-in ballots and ballot applications amounts to an unconstitutional poll tax.

A lawsuit filed in April by the American Civil Liberties Union and its Georgia chapter alleged that the postage requirement effectively imposes a poll tax and is an unjustifiable burden on the right to vote. The challenge was brought on behalf of voters and a group seeking to empower communities of color, the Black Votes Matter Fund.

The lawsuit asked a judge to find the requirement unconstitutional and to order the state to stop requiring voters to provide their own stamps to vote by mail-in ballot.
