An anonymous reader writes "Michael Geist reports that the Supreme Court of Canada has just issued a new online contracting decision that removes the ability for consumers to challenge mandatory arbitration clauses found in e-commerce contracts. (Decision is here.) The case involved a lawsuit against Dell Computer, which refused to sell hundreds of mistakenly priced computers purchased on their website. Dell tried to sidetrack a class action by claiming that all consumers were required to enter arbitration due to a clause buried in its contract via a hyperlink. Geist explains why the ruling may not be as unfavorable for Canadian consumers as it seems at first, in part because some provinces have already passed laws banning e-commerce sites from blocking class-action suits."
