MADISON, Wis. (AP) — A state appeals court has revived a lawsuit brought by a group protesting Gov. Scott Walker's collective bargaining bill at the Capitol in 2011. Six people who were issued citations for carrying signs sued state officials, saying their free speech rights were violated. The tickets were later dismissed by the Dane County District Attorney's Office. The 4th District Court of Appeals says the circuit judge made errors in dismissing the lawsuit. The three-judge panel also rejected the state's argument that a change in policy at the Capitol no longer made the issue relevant. The lawsuit will be sent back to Dane County Circuit Judge Frank Remington. The legislation that prompted massive protests at the Capitol largely ended collective bargaining for most state employees.
