MADISON, Wis. (AP) -- A Madison judge who halted Republican Gov. Scott Walker's public union restrictions has decided to retire.
Maryann Sumi announced on Monday she'll step down on May 30 after nearly 16 years on the bench. Then-Gov. Tommy Thompson appointed her as judge in 1998.
In 2011 she found that Republican lawmakers violated the state open meetings law during the run-up to passing Walker's union measure, which stripped most public workers of nearly all their collective bargaining rights. She stopped the restrictions from being implemented, enraging the GOP.
The conservative-leaning state Supreme Court overturned her ruling two months later. Debate on the case between the justices was so heated that Justice David Prosser wrapped his hands around Justice Ann Walsh Bradley's neck.
