“Thirty-three states have mandatory retirements between the ages of 70 and 75,” Knudson said. “Vermont is the highest with an age of 90.”
If passed by the Republican-run Legislature next year, all judges — except reserve or temporary judges — who are over 75 years old would have to retire immediately or within a matter of months.
According to the Wisconsin State Journal, "Such legislation would give Republican Gov. Scott Walker numerous opportunities to appoint judges to his liking to fill unexpired terms of judges and justices hitting the mandatory retirement age," including three state Supreme Court justices: Chief Justice Shirley Abrahamson, 81, Justice Pat Roggensack, 74, and Justice N. Patrick Crooks, 76.
The Wisconsin State Journal describes Abrahamson as "part of the three-member liberal minority on the court."
