How a scholar of international law balances presidential power with constitutional checks and balances
In short: Harold Hongju Koh, a Sterling Professor at Yale, has spent decades navigating the intersection of national security and human rights. From serving under four presidents to litigating high-stakes refugee cases, his work examines how legal frameworks can constrain executive authority and protect fundamental rights in an increasingly complex global landscape.
Harold Hongju Koh’s career is defined by his rigorous analysis of the American presidency. In his influential 1990 book, The National Security Constitution, he argued that the Iran-Contra affair exposed a dangerous imbalance in how foreign policy decisions are made. He contends that the Constitution demands meaningful consultation between the executive branch and Congress, rather than the president presenting lawmakers with completed military actions as faits accomplis. This scholarship earned him the Richard E. Neustadt Award, recognizing his contribution to understanding the American presidency.
Beyond his academic contributions, Koh has actively shaped legal policy through government service. He has held roles across multiple administrations, including as the top legal adviser at the Department of State from 2009 to 2013 and as a senior official overseeing human rights and labor issues from 1998 to 2001. His practical experience informs his academic work, which spans over 200 articles and numerous books. He has also served in the judiciary, clerking for Supreme Court Justice Harry Blackmun and Judge Malcolm Richard Wilkey.
Koh’s commitment to human rights is deeply personal, rooted in his family’s history of fleeing political instability in Korea. This background fuels his advocacy, most notably in his leadership of the 1992 litigation that secured the release of Haitian refugees detained at Guantanamo Bay. Whether testifying before Congress or arguing in international courts, Koh consistently emphasizes the necessity of humanizing security policies. He remains a prominent voice in debates over the limits of executive power, the legality of military interventions, and the enduring importance of international law in the 21st century.
