Theodore J. Boutrous, Jr. is a partner in the Los Angeles office of Gibson Dunn and one of the nation’s leading litigators. He is a member of the American Law Institute and a Fellow of the American Academy of Appellate Lawyers.

As The New York Times has noted, Mr. Boutrous has “a long history of pushing the courts and the public to see the bigger picture on heated issues.” The American Lawyer named Mr. Boutrous the 2019 “Litigator of the Year, Grand Prize Winner” and the Los Angeles and San Francisco Daily Journals in 2021 named him a “Top Lawyer of the Decade.” According to The National Law Journal, which in 2013 named him one of the “100 Most Influential Lawyers in America,” he “is known for his wise, strategic advice to clients in crisis and is a media law star.”

Mr. Boutrous has represented clients in federal and state appellate courts throughout the nation in a wide spectrum of cases, and he is currently serving as Co-Chair of the firm’s First Amendment and Free Expression Practice Group. He has argued hundreds of appeals, including before the Supreme Court of the United States, 12 different federal circuit courts of appeals, and 12 different state supreme courts (including 14 arguments in the California Supreme Court), and he has led a multitude of other complex civil, constitutional, and criminal matters. Mr. Boutrous has successfully persuaded courts to overturn some of the largest jury verdicts and class actions in history and prevailed in many cutting-edge cases. In 2011, he successfully represented Walmart before the Supreme Court of the United States in the Dukes case, which unanimously reversed what had been the largest employment class action in history and established important standards governing class actions (Wal-Mart Stores, Inc. v. Dukes). In 2013, he successfully represented the prevailing party in obtaining a unanimous Supreme Court decision enforcing the Class Action Fairness Act (Standard Fire Insurance Co. v. Knowles). Also in 2013, Mr. Boutrous successfully represented plaintiffs in the Supreme Court in a case invalidating California’s prohibition on same-sex marriage, Proposition 8 (Hollingsworth v. Perry), in which he also served as one of the lead trial lawyers and architects of the legal strategy that led to the landmark victory. In 2018, Mr. Boutrous successfully represented CNN and reporter Jim Acosta in bringing First Amendment and due process claims against then-President Donald Trump and other White House officials, forcing the White House to restore Mr. Acosta’s press credentials. “Litigators of the Week: Gibson Dunn’s Two Teds Score for the Free Press,” The AmLaw Litigation Daily (November 30, 2018). And in 2021, he secured a major victory for Hewlett-Packard Company when the California Court of Appeal affirmed a more than $3 billion verdict in HP’s long-running contract dispute with Oracle Corporation. “Litigators of the Week: Gibson Dunn Protects Its $3B Trial Win for HP Against Oracle on Appeal,” The AmLaw Litigation Daily (June 18, 2021).

As both a crisis management strategist and a seasoned appellate and media lawyer, Mr. Boutrous has extensive experience handling high-profile litigation, media relations, and media legal issues. He routinely advises clients in planning how to respond, and in responding, to crises and other especially significant legal problems that attract the media spotlight.

Mr. Boutrous received the Distinguished Leadership Award from PEN America in 2019 for his leadership in advancing First Amendment rights and protecting freedom of expression. As The Hollywood Reporter noted in naming him to its 2022 “Power Lawyers” list, “[w]hen issues of free speech are in play, Boutrous is the attorney on speed dial.” Mr. Boutrous was also named one of “Hollywood’s Top Entertainment Attorneys” in Variety’s 2026 Legal Impact Report, which highlighted his representation of OpenAI in a successful defense against the first-ever defamation case arising from generative AI output. The National Law Journal recognized him as a “First Amendment Rights Trailblazer” in 2020.

Numerous profiles of Mr. Boutrous and his practice have appeared in the media.

He is admitted to practice in England & Wales, Switzerland, the DIFC and the Eastern Caribbean Supreme Court (BVI).

Christopher has a distinguished reputation as a trial and appellate advocate in court and arbitration, with a track record of significant cases over more than 20 years in practice across a range of disciplines and industry sectors. His arbitration practice (for which he is Band 1 ranked by Chambers UK) spans both commercial and investment treaty matters, having served as counsel in approximately 30 investment treaty arbitrations alone. Christopher also maintains a renowned practice in enforcement matters having successfully enforced and defended enforcement of dozens of arbitral awards and judgments over decades. He has been involved in many of the seminal cases to come before the courts relating to enforcement, especially where states are concerned, most recently leading for the investors on the question of whether states have immunity in relation to the enforcement of ICSID awards where he succeeded at first instance and before the Court of Appeal, and led before the UK Supreme Court in December 2025. Alongside his active counsel practice, Christopher is able to give his clients the benefit of his substantial experience from the other side of the bench, having been appointed as arbitrator in over 50 arbitrations, including proceedings under ICSID, ICSID annulment committees, LCIA, ICC, SIAC, SCC, FAI, LMAA, and ad hoc rules.

In recognition of his work, Christopher was named International Arbitration Silk of the Year by Chambers & Partners in 2024 and was runner-up as International Arbitration Silk of the Year by Legal 500 for 2025 (having previously won both awards as junior counsel). He has been recognized as a Global Elite Thought Leader by WWL for several years. Prior to moving to Gibson Dunn in September 2025, Christopher was ranked as a leading silk in five practice areas: banking and finance, commercial litigation, energy and natural resources, international arbitration, and public international law, where clients describe him as “fearless” and “extraordinarily compelling” as an advocate, while offering “top of the line strategic advice.” He is also praised as “understand[ing] the political, financial and personal pressures that [clients] are under, and they completely trust him.” He is also noted as: “mesmerising on his feet” with a “considerable presence in courtrooms and hearings” and is widely regarded as “one of the best cross-examiners at the Bar.” These attributes have made him a go-to lead advocate in numerous high-value and business-critical disputes for sophisticated clients.

His prominence in the arbitration and international law fields is further underscored by his reappointment as the UK Member of the ICC International Court of Arbitration for a second term and his designation by HM Government to the ICSID Panels of Arbitrators and Conciliators.

Christopher’s international litigation work includes appearances at both trial and appellate levels in the DIFC Courts, the British Virgin Islands, and the Cayman Islands.
