A Quebec Court of Appeal judge on Wednesday authorized a class-action lawsuit against seven major Quebec retailers.

The plaintiffs in the lawsuit allege that they were misled into buying extended warranties prior to July 2010 by employees at Ameublements Tanguay, Brault & Martineau, Bureau En Gros, Corbeil Électrique, Sears Canada, Centre Hi-Fi and The Brick.

Since July 2010, businesses have been obligated to inform their clients that they are in fact protected by a legal warranty before offering them an extended warranty.

The people involved in the class-action lawsuit are asking for refunds on the extended warranties they purchased, plus punitive damages.
