A Wisconsin judge is set to hear a lawsuit challenging the state's collective bargaining restrictions. The 2011 law, known as Act 10, which stripped most public employees, including teachers, of their collective bargaining rights, is back in court. The case is being heard by a Dane County judge after the Wisconsin State Supreme Court, now with a liberal majority, agreed to hear the appeal. Unions are arguing for the overturning of the law, which had previously been upheld in earlier challenges and had sparked massive protests at the time of its enactment. The judge overseeing the case has been identified in the Walker recall petition. The law was originally enacted under then-Governor Scott Walker.
