This editorial explores some methodological difficulties that might be faced by the practice of the critique of international criminal law (ICL). It more particularly explores what it might mean to do an ‘internal’ critique of ICL, both on a disciplinary level and an intra-disciplinary level. The editorial also addresses two important issues: (i) the ambiguities of the normative agendas of critical legal scholars; and (ii) the difficulty of dialogue between critical legal scholars and positivists. The editorial concludes with the fact that while disciplinary dialogue might not always be possible, it will always take place on a personal, more complex level, in the Leiden Journal of International Law (LJIL) as elsewhere.
