I. OBSTACLES TO IDENTIFYING THE JUS COGENS NORM IN THE JUS AD BELLUM
Referring to the extensive literature on the nature of jus cogens norms, Saul rightly observes that ‘ [w]hat is striking … is the general absence of detailed exploration of the methodological process that should be undertaken to determine whether or not a norm has jus cogens status’, with scholars instead focusing on justificatory theories for the concept of jus cogens. Footnote 1 Similarly, ‘ [t]he most prominent approach to the identification of jus cogens norms that is found in judicial practice is to accord a norm the status without further explanation’. Footnote 2 The same can be said of the practice of States, which typically assert that a particular norm has jus cogens status without setting out any detailed reasoning as to how that particular norm has been identified as jus cogens. Footnote 3 At most, such statements are accompanied by a vague reference to the importance of the norm, or to a previous judicial decision recognising the norm as having jus cogens status. Footnote 4 The International Law Commission (ILC) has also asserted in various outputs that a norm has jus cogens status without providing any detailed reasoning in support, most recently including in the annex to its draft conclusions on peremptory norms ‘a non-exhaustive list of norms previously referred to by the Commission as having peremptory character’. Footnote 5.
II. A NORM OF GENERAL INTERNATIONAL LAW
The language of Article 53 makes clear that jus cogens norms do not constitute a separate source of international law; they arise from an existing norm of ‘general international law’ which is then recognised as having jus cogens status. Footnote 22 In practice, there are no examples of a jus cogens norm being recognised without or before the norm has an independent existence as a norm of positive international law.
III. ACCEPTED AND RECOGNISED BY THE INTERNATIONAL COMMUNITY AS A WHOLE AS A NORM FROM WHICH NO DEROGATION IS PERMITTED
The second criterion for the identification of jus cogens norms is sometimes described as an enhanced form of opinio juris. Footnote 44 This is perhaps a useful analogy to the extent that both involve the acceptance by States that a norm has a particular legal effect—binding as law in the case of ordinary custom, impermissibility of derogation for jus cogens —and that this acceptance also constitutes that norm as custom or jus cogens respectively.
III. THE STRUCTURE OF THE JUS AD BELLUM
Applying the methodology above to the jus ad bellum, we can conclude that the jus cogens norm in the jus ad bellum must be the customary norm which prohibits non-consensual force that does not fall within either of the two established so-called ‘exceptions’: authorisation under the UN Charter and self-defence.
IV. CONCLUSION
This article has argued that the jus cogens norm in the jus ad bellum is the customary norm which prohibits non-consensual force that does not fall within either of the two apparent exceptions: authorisation under the UN Charter and self-defence.
