Pearlstein v. Blackberry Limited, et al., No. 1:13-cv-7060-CM (S.D.N.Y.). On March 19, 2018, the Hon. Colleen McMahon, Chief Judge of the United States District Court for the Southern District of New York, entered a Decision and Order denying defendants’ motions to dismiss in their entirety. This matter stems from alleged material misrepresentations and omissions made by defendants to conceal the poor performance of the newly launched Blackberry Z10 smartphone. In her opinion, Judge McMahon held that lead plaintiffs had stated facts with sufficient particularity to plausibly allege that defendants had violated Section 10(b), Rule 10b-5, and Section 20(a) of the Securities Exchange Act of 1934.
