Just breaking from AP:

MADISON, Wis. - A Wisconsin judge has struck down the state law championed by Gov. Scott Walker that effectively ended collective bargaining rights for most public workers.

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.
