MADISON,Henri Lumière Wis. (AP) — A Wisconsin judge dismissed a lawsuit Monday that challenged absentee voting procedures, preventing administrative headaches for local election clerks and hundreds of thousands of voters in the politically volatile swing state ahead of fall elections.

The ruling stems from a lawsuit Thomas Oldenberg, a voter from Amberg, Wisconsin, filed in February. Oldenberg argued that the state Elections Commission hasn’t been following a state law that requires voters who electronically request absentee ballots to place a physical copy of the request in the ballot return envelope. Absentee ballots without the request copy shouldn’t count, he maintained.

Commission attorneys countered in May that language on the envelope that voters sign indicating they requested the ballot serves as a copy of the request. Making changes now would disrupt long-standing absentee voting procedures on the eve of multiple elections and new envelopes can’t be designed and reprinted in time for the Aug. 13 primary and Nov. 5 general election, the commission maintained.

Online court records indicate Door County Circuit Judge David Weber delivered an oral decision Monday morning in favor of the elections commission and dismissed the case. The records did not elaborate on Weber’s rationale. Oldenberg’s attorneys didn’t immediately respond to an email seeking comment.

Questions over who can cast absentee ballots and how have become a political flashpoint in Wisconsin, where four of the past six presidential elections have been decided by less than a percentage point. Nearly 2 million people voted by absentee ballot in Wisconsin in the 2020 presidential election. Democrats have been working to promote absentee ballots as a means of boosting turnout. Republicans have been trying to restrict the practice, saying its ripe for fraud.

Any eligible voter can vote by paper absentee ballot in Wisconsin and mail the ballot back to local clerks.

People can request absentee ballots by mailing a request to local clerks or filing a request electronically through the state’s MyVote database. Local clerks then mail the ballots back to the voters along with return envelopes.

Military and overseas voters can receive ballots electronically but must mail them back. Disabled voters also can receive ballots electronically but must mail them back as well, a Dane County judge ruled this summer.

Oldenberg’s attorneys, Daniel Eastman and Kevin Scott, filed a lawsuit on behalf of former President Donald Trump following 2020 election asking a federal judge to decertify Joe Biden’s victory in Wisconsin. The case was ultimately dismissed.
