A Wisconsin judge has struck down large parts of Republican Gov. Scott Walker’s controversial law curbing the collective bargaining rights of public employees. On Friday, Judge Juan Colás of Dane County Circuit Court overturned the law as it applies to city, county and school district workers, saying it violates their freedom of speech and association. Judge Colás’ order exempts public employees at the state level. Gov. Walker has vowed to appeal the order, saying it was issued by a “liberal activist judge.” Walker will likely seek to freeze the order during the appeal.
