Work highlights
Secured a unanimous victory in the US Supreme Court for Macquarie Infrastructure Corp. (MIC) and its former officers and directors in a federal securities class action stemming from a nearly $2bn 2018 stock drop. The Court’s ruling holds that silence does not equal fraud, even if SEC regulations require the issuer to speak.
