\ˈī -ˈāch -ˈel-ə-ˌthän\
Definition: An event in which people meet to engage in collaborative research and analysis on international humanitarian law (IHL). It's like a hackathon—yet one where the focus is not on creating computer programs and applications but rather on international law related to armed conflict. Think Wikipedia edit-a-thon but for the jus ad bellum and the jus in bello.
What and when?
