Louisiana plans to fight attempts by Allstate Corp. to have a federal court determine if new laws giving homeowners two years to file lawsuits against their insurers is legal. The laws extend from one to two years that homeowners with hurricane-related disputes with their insurers can sue their insurance companies. Under the law, victims of Hurricane Katrina would have until Sept. 1, 2007, to file suits, while victims of Hurricane Rita would have until Oct. 1, 2007.
