Impeachment in Wisconsin

Impeachment in Wisconsin is the main process by which the Wisconsin Legislature can bring charges and decide whether to remove state officers from their positions. A simple majority of the Wisconsin State Assembly can impeach an officer, after which the Wisconsin Senate acts as the court of trial, where a two-thirds majority is required to convict. In the event of a conviction, the punishment may be removal from office or removal and disqualification to hold state office.

Wisconsin also has an additional impeachment-like option for removal of judicial officers, known as "removal by address". Judges may be removed by address for any reason, but it requires a two-thirds majority of both chambers of the Legislature, and the judge must first be informed of the charges and allowed to make their case to the Legislature. Any elected official in Wisconsin may alternatively be removed through a recall election.

Only one official has ever been impeached in Wisconsin history: state circuit judge Levi Hubbell, in 1853—he was not convicted.
