The appellant was prevented from crossing a picket line at his workplace due to threats of violence from striking members of another union.
He applied for unemployment insurance benefits but was initially denied.
The Board of Referees and the Umpire allowed his appeal, finding he did not participate in the labour dispute.
The Federal Court of Appeal set aside the Umpire's decision, finding the issue of whether members of his grade or class participated had not been addressed.
The Supreme Court of Canada allowed the appeal, holding that the evidence established neither the appellant nor members of his union participated in the dispute, as they were prevented from working by genuine fear of violence.
