A labour arbitrator ordered a construction company to pay the union $447K in damages for its use of non-union workers. The company won the next round when the review court reversed the arbitrator’s ruling as incorrect and based on hearsay evidence. But it was the union that had the last laugh. The Nova Scotia Court of Appeal restored the arbitrator’s award. The review court used the wrong standard. Instead of correctness, she should have determined whether the arbitrator’s ruling was reasonable. And because it was reasonable, the high Court restored not only the ruling but the harsh penalty [Labourers International Union of North America, Local 615 v Stavco Construction Limited, 2019 NSCA 53 (CanLII), June 19, 2019].
