A federal appeals court has said Georgia’s expansion of requirements for quick processing of insurance claims is invalid.

The legislation, signed into law by Governor Nathan Deal in 2011, was long sought by the state’s doctors. A group of insurance companies challenged the law as in conflict with a federal statute, securing a temporary injunction of the law before it was set to go into effect. Last week, a panel of the U.S. Court of Appeals for the Eleventh Circuit upheld the preliminary injunction.
