Goldman Sachs is seeking leave to return to the U.S. Court of Appeals for the Second Circuit over the recent class certification in its long-standing litigation over housing bubble-era securities violation allegations.

The investment bank’s last sojourn at the appellate level ended in a victory. The appellate court struck down a previous class certification issued by U.S. District Judge Paul Crotty of the Southern District of New York, after finding the court failed to apply the correct evidence standard in determining the fraud-on-the-market presumption established by 1988′s U.S. Supreme Court’s decision Basic v. Levinson.
