MADISON, Wis. – Wisconsin Gov. Scott Walker wins again.

The U.S. 7th District Court of Appeals unanimously affirmed a lower court’s ruling last week that Gov. Walker’s landmark collective bargaining reform law is constitutional. The law, known as Act 10, was passed by Wisconsin lawmakers in 2011 over the loud objections of the state’s unions. The unions immediately sued to overturn the legislation, the Associated Press reports.

Act 10 essentially stripped away nearly all of the unions’ collective bargaining privileges, with the exception of negotiations over wage increases, which were limited to the rate of inflation unless local voters authorize more. The bill also required unions to recertify each year with a membership vote, to prove that at least half of the members want union representation, according to the news service.

The unions and their allies attempted to recall Walker from office over Act 10 in 2012, but more voters sided with Walker than when he was initially elected a year earlier. Walker is the only governor in the history of the United States of America to survive a recall election, according to the AP.

Voters stuck with Walker because Act 10 did precisely what it was intended to do – free school districts rom the expensive and unnecessary work rules and costs tied to union contracts.

As a result, school districts across the state saved millions in unnecessary labor costs in the midst of a national recession, which helped them avoid difficult layoffs that would have been necessary under the union-controlled system. It also gave school administrators the power to move teachers to the positions where they will be most effective, and to fire ineffective teachers with relative ease.

It also helped the state swing from a $3.6 billion budget shortfall to $2 billion in tax cuts under Walker’s leadership.

Unions argued in federal court that Walker’s Act 10 violated their members’ constitutional rights to free speech, association, and equal protection, but the courts have repeatedly ruled against Big Labor.

According to the AP, the ruling states Act 10 “does not proscribe any conduct by the unions themselves. It does not prohibit the unions from forming. It does not forbid them from meeting. Nor does it prevent the unions from advocating on behalf of their members in any way they see fit.”

Wisconsin Attorney General J.B. Van Hollen said the recent court ruling is “a victory for the law and Wisconsin taxpayers,” the AP reports.

“I appreciate the court’s work. I look forward to a successful resolution of the few remaining challenges to this important law,” he said.

Union attorney Bruce Ehike told the Milwaukee Journal Sentinel he’s consulting with his clients about a possible appeal to the U.S. Supreme Court.
