Allstate Insurance Company v. Nathan Harbour, Allstate Insurance Company v. Kenneth N. Mattison

Summary

The court held that the arbitration panels exceeded their authority by deciding the total benefits Allstate owed under the insureds' policies when the arbitration clauses submitted only the insureds' accident-related damages to arbitration. The court also held that the superior court improperly affirmed legal determinations concerning attorney's fees, subrogated medical-payment claims, and prejudgment interest without independently deciding those issues. The judgments were reversed and remanded for calculation of any amounts Allstate owed under the policies based on the damages determinations.
