British Columbia residents can now pursue class-action lawsuits against telecom service providers even if their contract says otherwise, the Supreme Court of Canada said Friday. The court overruled a B.C. Court of Appeal decision by ruling that the province's consumer-protection law allows consumers to get around a no class action clause in their contract if they suffered from deceptive business practices. The case reached the Supreme Court after a Vancouver resident wanted to certify a class action against Telus Corp. over how it calculates cellphone usage, but the company said B.C. consumers waive their rights to pursue a class action when they sign a contract. Telus said the contract instead directs disputes into private arbitration. Consumers in Ontario, Quebec and Alberta can also launch class actions against service providers.
