MADISON, Wis. (AP) -- Wisconsin Supreme Court Justice David Prosser is retiring after nearly 18 years on the court.
Prosser announced his retirement Wednesday in a news release from the court. The statement didn't give a reason, but Prosser is 73.
A court spokesman didn't immediately respond to a message from The Associated Press seeking an interview with Prosser.
Former Gov. Tommy Thompson appointed Prosser to the court in 1998. He is one of five conservative-leaning justices who make a majority on the court.
He made headlines in 2011 when he placed his hands around liberal-leaning Justice Ann Walsh Bradley's throat during an argument in chambers over a legal challenge to Gov. Scott Walker's law curtailing public workers' collective bargaining rights.
