Justice (Fmr) Douglas Lang advises clients on litigation and appellate strategies and presents appeals for pending matters in jurisdictions across the country. He is the co-chair of Thompson Coburn's firmwide Appellate Group.

Justice Lang collaborates with trial lawyers across the Firm on effective appellate strategies for clients, in some instances working directly on filings or arguing cases before appellate panels. Since returning to private practice, Justice Lang has appeared in state and federal courts across Texas and presented appeals in federal circuit courts and at the U.S. Supreme Court.

Drawing on over 16 years of judicial service and experience, Justice Lang provides prompt, strategic, and solution-oriented advice on potential or existing conflicts for clients in a wide range of businesses and industries. Justice Lang regularly represents clients before the appellate courts of Texas and federal appellate courts.

Justice Lang served on the Fifth District Court of Appeals in Dallas, a 13-judge appellate court with the highest case volume of the 14 intermediate appellate courts in Texas. While on the court, Justice Lang authored more than 2,100 opinions and participated in deciding more than 6,100 cases. During that same period, Justice Lang served for six years as a member of the Texas Multi-District Litigation Panel and as Chair of the Texas Commission on Judicial Conduct.

Justice Lang is renowned and highly respected for his tireless leadership in bar and community activities, his dedication to mentoring young lawyers, and his devotion to civility and ethics in the legal profession during his more than 40-year career. Justice Lang's belief in the importance of mentoring led him to author "Deeds, Not Words —Mentors As Guiding Lights of Integrity In The Legal Profession," a compilation of experiences recounted to him by a variety of bar leaders, judges, and successful attorneys.

Justice Lang is a frequent speaker at civic and continuing education events around Texas and nationally and has many published articles to his credit on appellate law, civility, and ethics.
