An investigation launched last month by a law firm into whether or not Research In Motion had violated securities laws resulted in the filing of a class action lawsuit late last month. After the lead plaintiff in the suit voluntarily withdrew her complaint on May 31st, however, it was unclear if the suit would be refiled. This week, Atlanta-based law firm Holzer Holzer & Fistel, LLC indeed refiled its class action suit with a new lead plaintiff, Gerald Chatlin. The news comes just before RIM is scheduled to report earnings on Thursday for the first quarter of its 2012 fiscal year.
