Chair of the firm’s Litigation Practice Group, Ben Mesches successfully leads appellate and litigation teams in high-stakes constitutional, commercial, and energy cases in state and federal courts across the country.

Ranked by Chambers USA, 2019-2021 (Chambers and Partners) as a leading Texas appellate lawyer, the prestigious directory praises Ben as “a tremendous brief writer and terrific oral advocate” and highlights his ability to “get the microscopic view but also zoom out to the big picture.”

Board certified in civil appellate law by the Texas Board of Legal Specialization, Ben has argued major cases at the Texas Supreme Court in each of the last three terms, on constitutional issues impacting billions of dollars in pension funds and a blockbuster electric-power industry case. In recent years, he has prevailed in two significant Fifth Circuit appeals involving renewable energy contracts. He is also handling appeals across the country that touch on emerging legal issues ranging from bitcoin, ownership of social media accounts, and insurance recovery.

Ben’s peers recognize his collaborative leadership style. At the firm, Ben leads the firm’s global litigation practice. He has served as president of the Texas Supreme Court Historical Society, chair of the American Bar Association’s Council of Appellate Lawyers—the only national appellate bench organization in the country—and chair of the Dallas Bar Association’s Appellate Section.

Ben is regularly invited to write and speak on litigation and appellate practice topics, including post-judgment strategy, practicing before the Texas Supreme Court, Fifth Circuit trends, jury charges, bankruptcy appeals, and the selection and preservation of issues for appeal.
