Gary Isaac is an experienced litigator and corporate advisor with extensive experience in mass tort, product liability, securities fraud and other complex litigation. Gary devotes significant time to pro bono matters involving human rights issues, including the landmark Guantanamo detainee litigation.

Gary has substantial experience in nationwide litigation overseeing the efforts of regional and local counsel in pretrial discovery, motion practice and trial preparation, and in evaluating settlement alternatives. Currently, for example, he is a member of the Mayer Brown team acting as national counsel for Medtronic, Inc. in In re: Medtronic, Inc., Sprint Fidelis Leads Products Liability Litigation (MDL 1905), coordinating the defense of personal injury and economic damages claims, including numerous putative class actions, brought in federal and state courts. Gary has helped develop Medtronic's overall legal strategy and defenses. He played a similar role in coordinating and overseeing motion practice and appellate work for Union Carbide Corporation in national asbestos litigation and in coordinating summary judgment and jury instruction strategy for The Dow Chemical Company in national silicone implant litigation.

Gary has applied his extensive experience in product liability and mass tort litigation and commercial disputes to advise clients on potential liability exposures in connection with formal and informal due diligence conducted for various corporate transactions. He has also advised clients on common law and contractual indemnity issues.

For the past five years, Gary has played an active role in the Guantanamo detainee litigation, both in the US Supreme Court and in the lower courts. Since fall 2005, Gary has been deeply involved in work with members of Congress concerning legislation to strip the courts of jurisdiction over the detainees' habeas corpus petitions. He has co-authored numerous amicus briefs in the detainee cases, including two amicus briefs in the Supreme Court in Rasul v. Bush and two amicus briefs in Boumediene v. Bush, in which the Supreme Court struck down as unconstitutional a 2006 law that attempted to strip the courts of jurisdiction to hear the detainees' cases. Gary also helped plan and coordinate the overall amicus effort in Boumediene, which included the filing of some 20 amicus briefs by a wide array of individuals and organizations. In fall 2008, Gary co-authored an amicus brief on behalf of former federal judges and former senior Justice Department officials in support of the successful cert. petition in Al Marri v. Pucciarelli . In April 2006, the Center For Constitutional Rights, which has been spearheading the Guantanamo litigation, honored Gary with its 2006 President's Award in recognition of his work. Gary is a frequent public speaker on the issues raised by the Guantanamo litigation.

Gary has practiced law at Mayer Brown since 1986. He is a member of the firm's Pro Bono Committee.
