A Montreal law firm has filed a proposed national class action lawsuit against BlackBerry-maker Research In Motion Ltd. following service disruptions to millions of Blackberry users around the world earlier this month. The Consumer Law Group Inc. announced Tuesday that it had filed the proposed class action with the Quebec Superior Court and is actively seeking participants to join. It claims that RIM is responsible for the loss of email services, BlackBerry Messenger communications and Internet access on BlackBerry devices between Oct. 11-14 and that RIM should compensate its customers. “The class action involves RIM's failure to take action to either directly compensate BlackBerry users or to indirectly compensate BlackBerry users by arranging for wireless service providers to refunds their customers and to take full responsibility for these damages,” the firm said in a release. “Anyone who was affected by the outage should contact our law firm.” BlackBerry services failed in much of Europe and Africa after a problem occurred with a core switch at RIM’s U.K.-based facilities on Oct. 10. Those problems caused a backlog in data transmissions, which started affecting North American traffic on Oct. 12. RIM has since announced $100 worth of free “gifts” available to affected customers through the company’s BlackBerry App World until the year. The firm’s lawsuit must be certified by a judge as qualifying as a class action suit before it can proceed.
