The controversial law that curbed the collective bargaining rights of public employees in Wisconsin has been struck down by Dane County Circuit Judge Juan Colas.

The law, if you remember, was championed by Gov. Scott Walker and it unleashed massive protests and even led to Democratic law makers to flee the state to forestall its passage. After it became law, union activists mobilized and triggered a recall vote, which Walker ultimately defeated.

The Associated Press reports:

“Dane County Circuit Judge Juan Colas ruled Friday that the law violates both the state and U.S. Constitution and is null and void. The ruling comes after a lawsuit brought by the Madison teachers union and a union for Milwaukee city employees.

“Walker spokesman Cullen Werwie says he is confident the decision will be overturned on appeal.

“It was not clear if the ruling means the law is immediately suspended. The law took away nearly all collective bargaining rights from most workers and has been in effect for more than a year.”

The Milwaukee Journal Sentinel reports that this means municipal workers return to what was the status-quo before the law was passed. State employees still have to abide by the new law.

“The ruling means that, unless it is overturned on appeal, school districts and local officials will have to return to the bargaining table with their workers in a much more significant way,” the Sentinel reports.
