It could be well into summer before the state Supreme Court decides whether it will get involved in a fight over a state law curbing collective bargaining rights for most public workers, under a schedule the court issued Wednesday.

The high court set oral arguments for June 6 on a request by Gov. Scott Walker’s administration to end a restraining order that is currently holding up implementation of the law and find that Dane County Circuit Judge Maryann Sumi overstepped her authority by issuing it on March 31.

Sumi issued the restraining order as part of an open meetings lawsuit brought by Dane County District Attorney Ismael Ozanne, which challenges the legality of a March 9 legislative conference committee meeting that stripped fiscal elements out of Walker’s budget repair bill.

Ozanne contends that the committee did not give the public proper notice before the meeting in violation of the state’s open meetings law.
