MADISON, Wis. (AP) – Republicans say a federal appeals court ruling upholding Gov. Scott Walker’s collective bargaining law affirms their argument from the beginning that the law is constitutional.   However, a state court ruling from last year striking down the law for school district and local government workers remains in effect. Other lawsuits are also pending.  Republican Attorney General J.B. Van Hollen says he hopes Friday’s ruling backing up the law will bring an end to the other lawsuits.  Statewide teachers union president Mary Bell says they are reviewing the ruling and their options. The decision can be appealed to the full 7th Circuit and the U.S. Supreme Court.  Democratic opponents of the law say they are disappointed in the ruling.
