A Wisconsin judge has struck down nearly all of the state law championed by Gov. Scott Walker that effectively ended collective bargaining rights for most public workers. Walker's administration immediately vowed to appeal the Friday ruling. Unions declared victory since had been vigorously fighting the law for some time. Unions claimed the ruling meant they could negotiate again, but Walker could seek to keep the law in effect while the legal drama plays out. This law was a crowning achievement for Walker that made him a national conservative star. This law also took away nearly all collective bargaining rights from most workers and has been in effect for more than a year.
