Union attorneys have asked a Dane County judge to let stand a ruling that Republican Gov. Scott Walker's collective bargaining changes are unconstitutional.
Dane County Circuit Judge Juan Colas' ruling earlier this month came as part of a lawsuit a Madison teacher union and a Milwaukee city workers union filed challenging the law.
Attorney General J.B. Van Hollen has asked Colas to stay the ruling pending an appeal. The unions' attorneys filed a brief Wednesday asking Colas to refuse.
They contend Van Hollen hasn't shown he could win an appeal or how allowing the ruling to stand would hurt the state. They also maintain Colas correctly ruled the law violates union members' free speech, association and equal protection rights.
Van Hollen has until Friday to reply.
