Allstate paid Michigan-level personal injury protection (PIP) benefits to an insured following a motor vehicle accident in Michigan.
TD Home accepted priority as the proper insurer but only reimbursed Allstate for Ontario-level benefits, arguing it was not obligated to pay Michigan-level benefits because it had not signed Michigan's Certification List.
An arbitrator ordered TD Home to reimburse the full amount.
TD Home appealed.
The Superior Court of Justice dismissed the appeal, finding the arbitrator's decision was reasonable and within his authority under the Arbitration Act to decide the dispute in accordance with law and equity.
