When Canadian unions pick a fight, they swing a mighty punch, as the province of Alberta recently discovered. Last month, based on a lawsuit brought by a Canadian union, the Supreme Court of Canada invalidated Alberta’s Personal Information Protection Act (PIPA). The court held, in Alberta (Information and Privacy Commissioner) v. United Food and Commercial Workers, Local 401, that only one element of PIPA – the restrictions placed on a union’s right to communicate to the public – was unconstitutional. But the provincial government asked the court to invalidate the whole Act so that the Alberta legislature could redraft it. The court agreed, and also suspended its decision for 12 months, in order to give the legislature time to rewrite the Act.
