In its June 2014 opinion in Erica P. John Fund, Inc. v. Halliburton Co., the United States Supreme Court held that in connection with a motion for class certification in a securities class action lawsuit, a defendant should have the opportunity to try to rebut the presumption of reliance by showing that the alleged misrepresentation did not impact the defendant company’s share price. The case itself was remanded to the district court for further proceedings in light of the Supreme Court’s ruling. On July 25, 2015, the District Court issued its ruling on the motion for class certification based on the principles the Supreme Court enunciated. A copy of the District Court ruling can be found here.
