Hon. Gregory G. Katsas
Gregory Katsas handles complex litigation in areas including administrative law, antitrust, constitutional law, employment discrimination, international law and arbitration, and products liability. He has argued more than 40 appeals, has won more than 30 appeals, and has argued in every federal appellate court including the U.S. Supreme Court.
Between 2001 and 2009, Greg served in many senior positions in the U.S. Department of Justice, including Assistant Attorney General for the Civil Division and Acting Associate Attorney General. In these positions, he handled or supervised most of the government's leading civil appeals. His own cases included such important topics as the detention of enemy combatants at Guantanamo Bay, the use of national security letters in major counterterrorism investigations, the applicability of the state secrets privilege in litigation about covert CIA activities, the closure of immigration hearings for suspected terrorists, and the constitutionality of federal statutes on subjects ranging from the Pledge of Allegiance to partial-birth abortion. He also oversaw all of the Civil Division's enforcement activities under the False Claims Act and the Food, Drug, and Cosmetics Act. He has testified before Congress eight times, on topics ranging from the material support statute to federal pleading standards under Ashcroft v. Iqbal.
In 2009, Greg was awarded the Edmund Randolph award for outstanding service, the highest award bestowed by the Department of Justice. Attorney General Michael Mukasey described Greg as "widely regarded as one of the Justice Department's most outstanding civil and appellate attorneys."
