Mr. Tulumello has been recognized by Chambers & Partners as a "superstar" and as one of Washington, D.C.'s leading appellate and commercial litigators.  Based on his "powerful courtroom advocacy," Benchmark Litigation described him as "clearly one of those once in a generation litigators" and "revered as being supremely talented in his securities and class action practice."  In June 2017, he was selected by the American Lawyer as Litigator of the Week based on his win in the Supreme Court of the United States in BNSF Railway v. Tyrell and trial court win in Wilson v. Frito-Lay (see "A Big League Double Play for This Gibson Dunn Lawyer").  He was recently profiled in The National Law Journal's 2017 Appellate Hot List and by Bloomberg BNA ("Deflategate Lawyer Heads to High Court in Securities Case").  Mr. Tulumello has repeatedly been selected by SuperLawyers in Washington, D.C. in the class action category. 

Constitutional and Appellate Practice and Global Legal Strategy

Mr. Tulumello has briefed and argued appeals raising significant federal and constitutional questions before the Supreme Court of the United States, the federal courts of appeals, and several state supreme courts, including the Supreme Courts of California, Florida, Illinois, Ohio, Oregon, and Texas.  Last Term, he successfully argued BNSF Railway v. Tyrell, an 8-1 decision that established important rules for general personal jurisdiction.  He is also counsel of record this Term in Leidos v. Indiana Retirement System, which involves the right to remain silent under the federal securities laws. He regularly advises companies facing legal challenges on multiple fronts (criminal investigations, SEC investigations, AG suits, and private litigation) on global legal strategy and best practices for litigation risk management.
