Wis. Admin. Code Judicial Commission JC 4.01
The commission shall consider any allegation of misconduct or permanent disability on the part of a judge or court commissioner from any source which reasonably indicates the existence of a cause justifying inquiry. Any person who submits a statement to the commission alleging misconduct or permanent disability by a judge or court commissioner may request that his or her identity be kept confidential, which request shall be complied with prior to the filing of a formal complaint or petition with the supreme court under s. 757.85(5), Stats. The executive director may seek additional facts relative to the allegation. The executive director shall make an initial determination of whether the allegation indicates the existence of a cause justifying review by the commission. If there is cause for review, the allegation shall be reduced to writing and filed as a request for investigation.
