International lawyerLegal strategistUN expertCESCRProfessor, AMUInternational speaker
Ludovic Hennebel acts as counsel in some of the most complex and sensitive international cases, involving legal, political, diplomatic and reputational stakes of the highest order.
He reads the law as a field of forces, identifies its lines of tension and its tipping points, and mobilises it as an instrument of protection, strategy and rebalancing.
Biography
A threefold authority: lawyer, professor, UN expert
Ludovic Hennebel combines a rare threefold experience: international lawyer, professor of international law and United Nations expert. Founder of Hennebel Avocats / Pacta Sunt Servanda, he acts in the most exposed transnational cases, where legal, political, diplomatic and reputational stakes intersect: INTERPOL red notices, extradition, international sanctions, lawfare, immunities, investment disputes, business and human rights, international protection mechanisms.
Professor of international law at Aix-Marseille Université and holder of an AMIDEX Chair of Excellence in international human rights law, he directs the Institute of International Humanitarian Studies (IEHI) and founded the Aix Global Justice Legal Clinic. His career has taken him from the Université libre de Bruxelles to Harvard Law School, New York University School of Law and Sciences Po Paris, after serving as Global Fellow at the Inter-American Court of Human Rights under the supervision of Judge Cançado Trindade (2003). An elected expert of the United Nations Committee on Economic, Social and Cultural Rights (CESCR), he chairs the Working Group on Individual Communications and is Rapporteur for a General Comment on economic, social and cultural rights in situations of armed conflict.
Author of some fifteen books, published notably by Cambridge University Press, Oxford University Press, Pedone, Bruylant and Dalloz, including International Human Rights Law: A Treatise (Cambridge University Press, 2025), he brings together scholarship, litigation practice and institutional strategy to design comprehensive responses in the most sensitive international situations.
International lawyer · Professor of international law · United Nations expert
The law is never neutral. It organises, constrains, exposes, protects, and at times subjugates and oppresses. His practice proceeds from this observation: the law is an instrument of power, but also a tool of resistance and transformation, once it is understood in its full strategic, political and institutional dimension. His approach is to read the law as a field of forces and to identify its lines of tension and tipping points (legal, institutional, diplomatic), where a seemingly locked situation can be moved.

United Nations mandates
Two successive mandates within the United Nations human rights system, affording direct knowledge of its contentious, diplomatic and normative dynamics.
2017 – 2020
Member of the Human Rights Council Advisory Committee
Chair of the Working Group on Communications on gross and flagrant human rights violations
2020 – 2030
Expert member of the Committee on Economic, Social and Cultural Rights (CESCR), elected by acclamation by ECOSOC in 2020, 2022 and 2026
Chair of the Working Group on Individual Communications · Rapporteur for a General Comment on economic, social and cultural rights in situations of armed conflict
These successive mandates confer first-hand knowledge of the internal workings of UN mechanisms, of the contentious dynamics between bodies, of the diplomatic practices of States and of the real room for manoeuvre in individual communications procedures: knowledge that few practitioners can claim.
International lawyer · Strategic litigation
As an international lawyer, Ludovic Hennebel appears before regional human rights courts, United Nations committees, INTERPOL bodies and international mechanisms in cases of high political, economic or diplomatic impact.
He also advises companies and economic actors on the design of complex legal strategies, upstream of or outside litigation, where the stakes call for a structural and unconventional approach.
His ability to bring together public international law, human rights, international criminal law, sanctions, immunities and geopolitical dynamics makes him sought-after counsel for complex disputes and preventive strategies alike, where standardised responses no longer suffice.
With Hélène Tigroudja, professor of international law and associate expert of the firm, he maintains a scholarly and litigation collaboration, of which their International Human Rights Law: A Treatise (Cambridge University Press, 2025) is a notable product.
Working languages
Ludovic Hennebel practises law in French, English and Spanish. All three are direct working languages.
Direct command of the instruments, case law and institutions in each of these three languages is no mere convenience of communication: it is constitutive of the firm's practice and of its ability to operate without intermediaries in international forums, regional courts and the most demanding diplomatic environments.

Hélène Tigroudja
Professor of international law · Vice-Chair, UN Human Rights Committee (2019–2026)
A stellar and immensely respected public international law and human rights lawyer: smart and thorough in his strategic litigation approach, with an amazing sense of legal creativity and rhetoric. Probably one of the most brilliant of his generation.
Paulo Sérgio Pinheiro
Brazilian Bar Association (OAB) · Former Chair, UN Commission of Inquiry on Syria (2011–2026) · Former member, Inter-American Commission (2003–2007)
Professor Hennebel is a formidable lawyer with an extraordinary experience in international law in the spheres of the UN and Inter-American human rights systems. There are very few lawyers able to operate in such different galaxies.
