Arbitrator's Failure to Consider Decisive Evidence Voids Award

A dispute arose concerning the validity of an arbitration award after one party challenged it, alleging the arbitrator had failed to consider a key piece of evidence presented during the proceedings. The challenging party argued this omission constituted a violation of the fundamental principles of justice and due process that must govern arbitration. The appellate court upheld the award, but the highest court quashed the decision, reasoning that an arbitrator's refusal to consider a relevant, pertinent, and decisive submission, which, if taken into account, could have altered the outcome, constitutes a miscarriage of justice and an abuse of authority, rendering the award legally void.
