During a legal strike, the appellant union picketed a court-house.
A union member and court employee crossed the picket line to work, prompting the union to initiate internal disciplinary proceedings against him.
The respondents successfully obtained an injunction restraining the union from proceeding with the discipline.
The Supreme Court of Canada dismissed the union's appeal, holding that picketing a court-house constitutes criminal contempt of court because it impedes access to justice.
Consequently, the union had no lawful right to discipline a member for refusing to respect an unlawful picket line.
