Randy M. Mastro, a partner in the New York office of Gibson, Dunn & Crutcher, is Co-Chair of the Firm’s Transnational Litigation and Crisis Management Practice Groups.  He also serves on the Firm’s Management and Executive Committees.  He routinely ranks among the nation’s leading litigators and trial lawyers in surveys of corporate counsel and other practitioners.  The National Law Journal named him among the “100 Most Influential Lawyers in America,” recognizing him as one of the “100 lawyers in the United States who have shaped the legal world through their work,” and noting “his ease in the courtroom, delivery of arguments and command of the law have made Randy one of the most in-demand attorneys in the country by big-name clients.” Lawdragon Magazine has repeatedly cited him among the “500 Leading Lawyers in America.”  In Chambers USA, he is a top-ranked litigator and trial lawyer nationally, praised for his “exceptional public reputation” as a “tough, smart,” “outstanding” litigator who “delivers fantastically well in court” and is “unafraid” of challenging cases.  In The Legal 500—US Edition, he has been featured among the ‘Leading Trial Lawyers’ in the country, with corporate counsel saying he is “immensely impressive,” “simply excellent,” “flawless,” “captivating,” and “in a league of his own” in the courtroom, and “deserves an Academy Award” for “bringing a sense of drama and theater to his courtroom appearances.” Benchmark Litigation’s Guide to America’s Leading Litigation Firms and Attorneys has recognized him as a “brilliant and effective” “Litigation Star” who “always brings a fresh perspective and will fight you to the end,” with one peer joking, “You do not want to meet Randy down a dark alley.  But you REALLY don’t want to meet him in a lighted courtroom,” while another peer noted, “I’ve never gone against Randy before myself but I’ve seen him at work and I can only imagine that going against him must be like wrestling an alligator.”  The New York Observer named him to its inaugural “New York Political Power” list, describing him as “a formidable courtroom scrapper.”  The New York Times has called him “the go-to lawyer for companies” suing the government, a “household name,” and a “fierce and combative litigator”; and The New Yorker has described him as a “merciless litigator,” “even by the pugilistic standards of the New York bar,” who “springs to life” and “is transfixing” in “the courtroom.”  Among many high-profile matters, Mr. Mastro won a two-month RICO trial barring the enforcement of a $9 billion Ecuadorian judgment against Chevron, and led the successful effort to defeat the City’s controversial West Side Stadium project.  Currently, he is representing the Office of the Governor of New Jersey in connection with allegations concerning George Washington Bridge toll lane closings at Ft.

After graduating cum laude from Yale College and the University of Pennsylvania Law School, where he was the school’s moot court champion, Mr. Mastro served as law clerk to Justice Alan B.
