International humanitarian law
International humanitarian law operates on a strict division between rules applicable in international armed conflict and internal armed conflict. This dichotomy is widely criticized. 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. On the other hand, a more systemic perspective explains that international humanitarian law represents a function of international human rights law; it includes general norms that apply to everyone at all time as well as specialized norms which apply to certain situations such as armed conflict and military occupation (i.e., IHL) or to certain groups of people including refugees (e.g., the 1951 Refugee Convention), children (the 1989 Convention on the Rights of the Child), and prisoners of war (the 1949 Third Geneva Convention).
