MADISON, Wis. — After three years of legal battles, the war for Gov. Scott Walker’s cornerstone public-sector collective bargaining reforms is over, with the state Supreme Court on Thursday upholding Act 10 in its entirety.

Altogether, it was a big day for conservative causes. Wisconsin’s high court also ruled in favor of the state’s controversial voter ID law, but that matter is far from settled.

The Supreme Court, in a 5-2 decision, with liberal Judge Patrick Crooks begrudgingly agreeing Act 10 is constitutional, put an exclamation point of approval on the public employee labor law that sent thousands protesters to the state Capitol and 14 Democratic senators fleeing across the state line in a bid to stop it.
