In this iteration of the Review 's “Beyond the Literature” series, we have invited Ezequiel Heffes to introduce his recent book Detention by Non-State Armed Groups under International Law , before then posing a series of questions to Tilman Rodenhäuser, René Provost, Mariana Chacón Lozano and Katharine Fortin, who have agreed to serve as discussants of the book. Tilman Rodenhäuser is a Legal Adviser at the International Committee of the Red Cross (ICRC), with particular expertise in non-State armed groups (NSAGs) and detention. René Provost is the James McGill Professor of Law at McGill University and has written extensively on public international law, including his recent monograph Rebel Courts: The Administration of Justice by Armed Insurgents. 1 Mariana Chacón Lozano has served as the Operational Legal Coordinator for the ICRC in Colombia since October 2020 and has worked for the ICRC since 2011. Katharine Fortin is Associate Professor at the Netherlands Institute of Human Rights within the Faculty of Law, Economics and Governance of Utrecht University. The Review team is grateful to all four discussants, and to Ezequiel, for taking part in this engaging conversation.
