Dean and Anthony B. Buzbee Endowed Dean's Chair, Texas A&M University School of Law
A graduate of Princeton University's Woodrow Wilson School of Public and International Affairs and Yale Law School, Robert B. Ahdieh served as law clerk to Judge James R. Browning of the US Court of Appeals for the Ninth Circuit before his selection for the Honor's Program in the Civil Division of the US Department of Justice.
While still in law school, Ahdieh published what remains one of the seminal treatments of the constitutional transformation of post-Soviet Russia: "Russia's Constitutional Revolution—Legal Consciousness and the Transition to Democracy." Ahdieh's work has also appeared in the Boston University Law Review, Michigan Law Review, theMinnesota Law Review, the NYU Law Review, and the Southern California Law Review, among other journals.
Ahdieh’s scholarly interests revolve around questions of regulatory and institutional design, especially in the financial arena. His particular focus has been on various non-traditional regulatory structures and modes of regulation, including those grounded in dynamics of coordination. Though relatively less studied in the legal literature, the framework of coordination holds significant promise both in helping us theorize existing regulatory patterns and in defining new regulatory constructs for the future.
Ahdieh has explored regulatory and institutional design in a variety of transactional areas, including corporate and securities law, international trade and finance, and contracts. Within these, his work has emphasized two particular patterns of coordination. The first—intersystemic governance—draws on domestic regimes of federalism and transnational regimes of global governance and subsidiarity to highlight the potential benefits of complex systems of overlapping jurisdiction. The second draws on the dynamics at work in so-called “coordination games” to highlight distinct occasions for potential regulatory intervention, as well as various non-traditional regulatory forms, in our modern economic, social, and political order.
During the 2007–2008 academic year, Ahdieh was a visiting professor and the Microsoft/LAPA Fellow at Princeton University's Program in Law and Public Affairs. In Spring 2014, he served as Douglas McK. Brown Visiting Chair in Law, University of British Columbia. He has also visited at Columbia and Georgetown law schools, as well as numerous law schools overseas.
Texas Supreme Court
Justice Jimmy Blacklock was appointed to the Texas Supreme Court in January 2018 by Governor Greg Abbott. Before that, Jimmy served as Governor Abbott’s General Counsel and in the Attorney General’s Office under then-AG Abbott. While at the AG’s Office, he handled appeals and trials of constitutional cases in state and federal court involving matters such as federalism, religious liberty, and the separation of powers. As Deputy Attorney General for Legal Counsel, he oversaw the Open Records and Opinions divisions of the AG’s Office. Earlier in his career, Jimmy was appointed by President George W. Bush to serve in the Civil Rights Division of the U.S. Department of Justice, and he worked in private practice in Houston and Austin. He clerked for Judge Jerry Smith on the U.S. Court of Appeals for the 5th Circuit after graduating from U.T.-Austin (B.A., Plan II/History) and Yale Law School. He was born in Houston and now lives in Austin with his wife and three daughters.
Costa is a partner in Gibson Dunn’s Houston office and co-chair of the firm’s Trials Practice Group. Mr. Costa offers clients a unique perspective as the only former federal trial and appellate judge trying cases and leading investigations. His broad experience—having handled complex civil and criminal matters, at trial and on appeal, as advocate and judge—allows him to offer invaluable skills and strategic insights.
Before joining Gibson Dunn, Mr. Costa served for more than ten years as a federal trial and appellate judge. He served on the U.S. Court of Appeals for the Fifth Circuit from 2014 to 2022. After his nomination by President Obama, the Senate confirmed him by a vote of 97-0. No federal appellate judge nominated since has received more votes. Mr. Costa first served as a district judge for the Southern District of Texas from 2012 to 2014. When appointed to the bench, he was the youngest-sitting federal judge at age 39. Mr. Costa presided over thirty federal trials in four different venues (he continued handling district court matters while serving on the court of appeals). He wrote precedential opinions in almost every area of the law, including antitrust, intellectual property, class actions, international arbitration, securities fraud, bankruptcy, conflicts of law, labor and employment, oil and gas, False Claims Act, administrative law, constitutional law, and criminal law. In press accounts of his tenure, he was described as an “exceptionally gifted jurist” with a “towering intellect” who was “respected by all sides.” The Federal Judicial Center invited Mr. Costa on multiple occasions to teach new federal district judges.
Before taking the bench, Mr. Costa was an Assistant U.S. Attorney in Houston from 2005 to 2012. As a prosecutor, he tried more than 15 jury trials, including serving as a lead prosecutor of Allen Stanford, the head of Stanford Financial Group, for orchestrating a multibillion-dollar international fraud scheme. Mr. Costa is featured in a documentary about the case, The Man Who Bought Cricket.
