As certain causes of action alleged by the plaintiffs were not certified, the representative plaintiffs are seeking leave to appeal to Ontario’s Divisional Court. The court’s decision on leave is outstanding. An update will be posted once the court’s decision is released.

A certification motion to determine whether the claim can proceed as a class action was heard during the week of August 31, 2015. On October 5th, 2015, the decision was released certifying the action as a class proceeding. Click here to read the full decision.

This proposed class action alleges that several defendants conspired with each other to raise, maintain, fix and/or stabilize the price of lithium-ion batteries and lithium-ion battery products sold in Canada and elsewhere from January 1, 2000 until at the earliest December 31, 2011.

Lithium-ion batteries are rechargeable battery contained within consumer electronic products such as mobile phones, MP3 players and notebook computers.

The action alleges that the defendants and unnamed co-conspirators participated in illegal, secretive meetings and made agreements relating to the prices, market share divisions and production levels for lithium-ion batteries.

Sotos LLP is bringing this action together with the law firms Siskinds LLP based in London, Ontario and Camp Fiorante Matthews Mogerman based in Vancouver, B.C.
