Shaun Clarke


Shaun Clarke tries civil and criminal cases. 

In August 2017, he obtained a "Not Guilty" verdict in a federal jury trial for our client who was charged with insider trading arising from the merger of The Shaw Group with Chicago Bridge & Iron.  In 2016, he obtained a "Not Guilty" verdict in a federal jury trial for the BP rig worker charged with causing the Deepwater Horizon oil spill. He has won jury trials for clients in area ranging from taxation to civil rights, from personal injury to complex criminal frauds.

Described by Chambers USA as a "master in handling government investigations on behalf of a nationwide clientele," Mr. Clarke has been selected for inclusion in The Best Lawyers in America for over a decade, and has been named a Litigation Star by Benchmark Litigation and a Texas and Louisiana SuperLawyer.  Mr. Clarke honed his trial skills as a San Francisco Deputy City Attorney and as an Assistant United States Attorney in New Orleans. He has led defense teams in nearly every area of white collar defense and has represented clients ranging from Fortune 50 companies to individual employees. He has successfully represented clients in SEC and other government investigations as well as at every level of both the civil and criminal court systems. A few other noteworthy criminal cases include

  • the landmark "constructive amendment" reversal in U.S. v. Hoover;
  • reversal of a $17 million restitution award in U.S. v. D.L.;
  • dismissal of criminal charges against an individual under the Commodities Exchange Act in U.S. v. Radley;
  • successful representation of a former New York Yankee in the congressional investigation into performance enhancing drug use;
  • successful defense of a New Orleans hospital in the investigation of alleged euthanizing of patients following Hurricane Katrina.

Mr. Clarke has enjoyed equal success in civil litigation:

  • In Shell v. St. Charles Parish, he prevailed at trial on behalf of a corporate client that challenged taxes imposed by a local entity;
  • in LOPA v. Shalala he obtained an injunction that prevented the federal government from implementing a system that would have limited access to transplants for Louisiana residents;
  • he won dismissal of civil RICO charges filed against a major law firm and one of its partners; and
  • he successfully represented employee of U.S. defense contractor who was falsely accused in a civil suit of raping a coworker in Iraq.

Mr. Clarke is admitted to the Bars of Texas and Louisiana and regularly speaks before their members on issues related to trial tactics, white-collar and environmental crime, and corporate investigations.
