The relationship between international human rights law and international humanitarian law is disputed among international law scholars. This discussion forms part of a larger discussion on fragmentation of international law. While pluralist scholars conceive international human rights law as being distinct from international humanitarian law, proponents of the constitutionalist approach regard the latter as a subset of the former. In a nutshell, those who favor separate, self-contained regimes emphasize the differences in applicability; international humanitarian law applies only during armed conflict.
