The U.S. Court of Appeals for the Second Circuit on Wednesday revived a securities class action accusing Chinese internet firm Qihoo 360 Technology of concealing its plans for a backdoor listing that took the company public following a 2016 merger.

The ruling, from a unanimous panel of the Manhattan-based appeals court, reversed a lower court’s decision that the plaintiffs failed to allege that Qihoo and its executives made misleading statements in proxy materials.
