Arizona Gov. Jan Brewer's lawyers plan to file the first brief Thursday in their appeal of a ruling that blocked the most controversial elements of the state's tough new immigration law.
Brewer wants the 9th U.S. Circuit Court of Appeals in San Francisco to lift U.S. District Judge Susan Bolton's ruling last month.
The governor's office says Bolton abused her discretion by applying the wrong legal standards and basing her ruling on the federal government's speculation that it would be harmed by Arizona's law.
The U.S. Justice Department went to court in a bid to invalidate the law. The Justice Department had no immediate comment Thursday.
The governor faces a Thursday deadline for filing the brief but hadn't done so by early afternoon.
