A federal appeals court has ordered an en banc rehearing of a challenge to a California statute that has spawned lawsuits against insurance firms on behalf of victims of the Armenian genocide.

The case, against two German insurers and their parent company, Munchener Ruckverischerungs Gesellschaft A.G., or Munich Re, will be reheard in oral arguments during the week of Dec. 12 in San Francisco, according to a Nov. 7 order by the 9th U.S. Circuit Court of Appeals.
