Over the coming week, along with Opinio Juris, we are happy to co-host a symposium on Compliance in Armed Conflict: New Avenues to Generate Respect for Humanitarian Norms, co-organized by Ioana Cismas and I.
We will have the honor to read about innovative compliance generation strategies from a list of renowned scholars and practitioners, including : Emiliano Buis, Katharine Fortin, Hyeran Jo, Fiona Terry, Ahmed Al-Dawoody, Jonathan Zaragoza, Yolvi Padilla, Chris Rush, Mohamed Assaleh, Louise Sloan, Ibrahim Salama, Michael Wiener, Nontando Hadebe, Annyssa Bellal, Pascal Bongard, Melina Fidelis-Tzourou, Anki Sjöberg and Anne Schintgen. Ioana and I will also contribute with an Introductory piece on Monday (19/10).
As this is a co-hosted symposium, half of the contributions will be found here at Armed Groups and International Law and the other half at Opinio Juris. We will try to cross-link, but keep an eye on both websites to follow along. We look forward to the exchange!
