The Schwarzenegger administration filed an appeal Wednesday in a lawsuit over his furloughs of state workers, contesting a decision by the controller to restore pay for prison guards.

Last year, Gov. Arnold Schwarzenegger ordered some 200,000 state employees to take three days off a month without pay, cutting their paychecks by 14 percent to help close the state's budget gap. The California Correctional Peace Officers Association sued, arguing that guards are losing three days' pay each month, but can never take the time off because prisons operate around the clock.

Alameda County Superior Court Judge Frank Roesch sided with the 30,000-member union last month. On Tuesday, state Controller John Chiang said he intends to restore guards' full pay to comply with that ruling. The guards' court victory does not affect about two dozen other union lawsuits opposing the furloughs.

Schwarzenegger spokesman Aaron McLear said the administration will impose layoffs and end guards' extra pay and pension benefits if an appeals court doesn't quickly block the decisions by Roesch and Chiang. The state filed the appeal in the 1st District Court of Appeal in San Francisco.
