Mr. Cooney has been a principal of McKool Smith since 2009, having moved from Davis Polk & Wardwell after more than 35 years of practice there.  The mainstay of his practice has always been complex civil and criminal litigation.  He has represented individuals and institutions in grand jury and other governmental investigations relating to a wide range of criminal charges, involving securities and insider trading, mail and wire fraud, tax, antitrust, the Foreign Corrupt Practices Act, government contracting, OFAC violations, FDA violations, accounting irregularities and environmental accidents.  Some of his most successful criminal representations remain confidential, as they ended in the prosecutor’s decision not to go forward with a public charge against his client.

His practice has commonly involved representation of foreign clients and working as a team with foreign counsel.  The assignments that he handled for Siemens in connection with its FCPA prosecution, for Shell in its internal investigation of its oil reserves and for Exxon in an FCPA investigation concerning Kazakhstan are typical of such matters.

Since joining McKool Smith, his work has included, among other things, representing an executive of Fairfield Greenwich Group in civil litigation and criminal, regulatory investigations relating to the Madoff scandal, foreign institutions in civil litigation relating to the Madoff scandal, an individual partner in a hedge fund in the investigation of possible insider trading, a criminal investigation of false filings by a Korean institution in an antitrust inquiry, a civil antitrust matter for Lockheed, individuals in investigations relating to LIBOR and OFAC, and several FCPA cases.

Mr. Cooney served as Assistant United States Attorney for the Southern District of New York from 1972 to 1977, becoming chief of the narcotics unit.  As a prosecutor and defense counsel, he tried numerous criminal cases to verdict before federal juries.  Among his noteworthy trials are his representation of Recognition Equipment Incorporated in its acquittal for alleged bribery of the vice chairman of the United States Postal Board of Governors; the estate of Charles Shipman Payson in successfully rebutting a challenge to his will; and, Winfield Dunseath in his acquittal at trial for alleged foreign currency fraud.

He is a Fellow of the American College of Trial Lawyers and has acted as chairman of its Committee on the Federal Rules of Criminal Procedure.  He has taught in the Harvard, Cardozo and Fordham law schools’ trial practice programs and at white-collar crime courses held at Georgetown University Law Center. He is a graduate of Duke University School of Law, where he served as Note Editor of its Law Journal. 

Chambers USA (2008) described him as “a passionate advocate for his client.”
