State employee labor unions have been challenging the governor's two-day-a-month furloughs since he issued the order for 200,000 state workers in February 2009.
Schwarzenegger later expanded the furlough to three days a month, which roughly translates to a 14-percent pay cut for government employees.
The governor said the order was intended to save money as the state faced a severe budget crisis.
The order has sparked more than two dozen lawsuits.
