9 The Responsibility to Protect is an emerging international legal doctrine under which all states have obligations to respond to genocide, war crimes, ethnic cleansing and crimes against humanity whenever they occur.

10 See for example Cassimatis, AE “International humanitarian law, international human rights law and the fragmentation of international law” (2007) 56 International and Comparative Law Quarterly 623 at 630CrossRefGoogle Scholar, noting that conflict between the peremptory norms of the two bodies of law is “probably only a theoretical possibility”.

11 See the well-known statements by the International Court of Justice on the issue in Legality of the Threat or Use of Nuclear Weapons ICJ Rep 1996 226, para 25 and Legal Consequences of the Construction of a Wall in Occupied Palestinian Territory ICJ Rep 2004 136, para 106; the court subsequently cited these decisions without specifically referring to IHL as the lex specialis in Armed Activities on the Territory of the Congo (Democratic Republic of the Congo v Uganda) ICJ Rep 2005 168, para 216.

It should be noted that, since the publication of the last-mentioned article, the US has changed its position on the issue of the application of IHRL during conflict that the article discusses, and the US now accepts that the IHRL and IHL “are in many respects complementary and mutually reinforcing”; see Fourth Periodic Report of the USA to the UN Committee on Human Rights Concerning the International Covenant on Civil and Political Rights (30 December 2011), para 507.

20 Although this article will cast the net somewhat wider still, it is also worth noting that the International Law Commission's emerging approach to the sources relevant to identifying customary law treats “resolutions, declarations, recommendations and decisions” of regional organizations as potentially valuable evidence.

27 51 African countries have ratified the four main Geneva Conventions and the International Covenant on Civil and Political Rights; 49 have ratified Additional Protocol I. The relationship between the responsibility of the sending state and the control it exercises has been the subject of important recent European developments.
