With over forty years of experience as a civil litigator in New York and Washington, D.C., Mr. McMahon and his legal team have been successfully representing both plaintiffs and defendants in a wide array of cases. Most notably, the firm represents 11 defendants in the In re: Terrorist Attacks on September 11, 2001, 03 MDL 1570 in the U.S. District Court for the Southern District of New York— one of the most complicated cases in the country. We have successfully dismissed five of those defendants from district court and are now diligently working to defeat the appeal. 

Martin F. McMahon & Associates has extensive experience in handling cases involving the Anti-Terrorism Act, the Alien Tort Statute, the Torture Victim Protection Act, the Foreign Sovereign Immunities Act, and the Foreign Corrupt Practices Act.
