Does the Court In Wisconsin Believe It is Superior to the Legislature?

Yesterday a Court Judge ruled that the Wisconsin Labor law cannot be enforced.  Amazing how a single Judge sets herself up against the Governor and the legislature of a sovereign State.  It is disheartening for average citizens to watch such judicial legislation.  The Judges are supposed to rule on the legality of the law under the constitution.  So what is the Judge doing here?  Is it judicial politics or does she have legitimate reason to tell the legislature, in due order assembled, that it is not allowed to pass laws?  I understand this may seem simplistic but the people do elect legislators and Governors and they expect their decision to be respected unless the legislature does something egregiously harmful to the citizens of the State.  Do we really think that limiting government employees collective bargaining rights, and telling them to pay 8% of their pension of 12 5 of their health insurance is harmful to the State.  I am sure that the majority citizens of that State pay as much or more into their plans.  So what’s the problem?
