"Today's suit includes four cases with clear evidence of unlawfulness, such as illegally altering absentee ballot envelopes, counting ballots that had no required application, overlooking unlawful claims of indefinite confinement, and holding illegal voting events," the campaign said in a statement.
The allegedly unlawful actions affected at least 221,000 ballots, according to campaign officials.
Michael Gableman, a former Wisconsin Supreme Court justice, told The Epoch Times that the guidance went against state law. A spokesman for the Wisconsin Elections Commission said the guidance was approved by the commission unanimously in 2016.
Another alleged violation of state law, the Trump campaign says, is municipal clerks issuing mail-in ballots to voters who did not apply for them.
"Wisconsin law expressly requires that absentee ballots may not be issued without receiving a written application requesting the ballot. Despite clear statute, clerks in Madison and Milwaukee issued thousands of absentee ballots without collecting a written application during the two-week in-person absentee voting period that ran from October 20, 2020, through November 1, 2020," the campaign said.
The campaign also accused the city of Madison of creating illegal polling locations at parks and other places through voting events called "Democracy in the Park."
Requests for comment sent to the office of Madison Mayor Satya Rhodes-Conway and the Madison city clerk's office weren't returned. The Milwaukee city clerk directed an inquiry to the city's Election Commission, which didn't respond to an email.
Democratic presidential nominee Joe Biden's campaign didn't respond to a request for comment.
A Wisconsin Supreme Court spokesman acknowledged receipt of the filings in an email to The Epoch Times. He said there is no set timeline for the court to decide whether or not to take the case.
“The people of Wisconsin deserve election processes with uniform enforcement of the law, plain and simple. During the recount in Dane and Milwaukee counties, we know with absolute certainty illegal ballots have unduly influenced the state's election results. Wisconsin cannot allow the over three million legal ballots to be eroded by even a single illegal ballot,” Jim Troupis, counsel to the campaign, said in a statement.
“We will continue fighting on behalf of the American people to defend their right to a free and fair election by helping to restore integrity and transparency in our elections.”
Several non-campaign lawsuits are being considered by courts in Wisconsin.
Biden is marked as the winner of the state by about 20,000 votes.
