This policy underlies the principle of jus cogens ).

The Vienna Convention defines jus cogens norms by their non derogable character.

In regard to the complex relationship between obligations erga omnes and norms of jus cogens, it was observed that while all jus cogens obligations had an erga omnes character, the reverse was not necessarily true.

A jus cogens norm is defined as a norm accepted and recognized by the international community of States as a whole as a norm from which no derogation is permitted. Thus, by definition, norms belonging to the category of jus cogens apply in all situations and are unaffected by the outbreak of armed conflict.

The concept of jus cogens has been widely accepted by the doctrine and finds reflection in the VCLT.

While hierarchy may solve conflicts of norms, it was acknowledged that conflicts between norms of jus cogens, obligations erga omnes, and obligations under Article 103 of the Charter could also emerge.

It was clearly understood that, while norms of jus cogens and obligations arising under Article 103 of the Charter addressed aspects of hierarchy, obligations erga omnes were more concerned with the scope of application of norms, rather than hierarchy.

Compliance with peremptory norms

Some members of the Study Group doubted that the principle of harmonization had a particular role to play in the relationship between norms of jus cogens and other norms.

Discussion of the Preliminary Report on Hierarchy in international law jus cogens, obligations erga omnes, Article 103 of the Charter of the United Nations, as conflict rules

Some commentators have made the same argument with respect to obligations erga omnes, or confused jus cogens norms with obligations erga omnes.

It was also noted that norms of jus cogens, obligations erga omnes, and obligations under the Charter of the United Nations (Article 103 of the Charter) should be treated as three parallel and separate categories of norms and obligations, taking into account their sources, their substantive content, territorial scope, and practical application.

The Study Group identified the need to address the effects of the operation of norms of jus cogens, obligations erga omnes, and obligations under Article 103 of the Charter (or similar treaty provisions).

The foregoing shall be without prejudice to any decision that the parties may, by mutual agreement and without a breach of jus cogens, make at any time.

As regards the relationship between norms of jus cogens and obligations under Article 103, some Members highlighted its complex nature, while others stressed the absolute priority of the former over the latter.

A peremptory norm (also called jus cogens or ius cogens or Latin for compelling law ) is a fundamental principle of international law that is accepted by the international community of states as a norm from which no derogation is permitted.

The Study Group also considered a revised report by Mr. Z. Galicki on Hierarchy in international law jus cogens, obligations erga omnes, Article 103 of the Charter of the United Nations, as conflict rules .

Treaties or treaty provisions codifying jus cogens rules

The other questions addressed in the report related to the compatibility of reservations with the object and purpose of the treaty, stipulated in article 19 (c) (validity or invalidity of reservations relating to the application of internal law, customary rules or the rules of jus cogens).

The rationale of hierarchy in international law found its basis in the principle of the international public order, and its acceptance is reflected in examples of such norms of jus cogens, obligations erga omnes, as well as treaty based provisions such as Article 103 of the Charter.

Norms of jus cogens were non derogable and the effect of this operation was to produce the invalidity of the inferior norm.

We would also like to point out here that our praise of the work of UNCITRAL can be attributed to the fact that we appreciate the difficulty of establishing standard international rules on the subject of private law, which is applied by the local courts of justice, because of the way in which this can be incompatible, firstly, with local rules that give commands, secondly, with matters of public order and, thirdly, with general policy.

On this basis, the Study Group agreed that it would not seek to produce a catalogue of norms of jus cogens.

Paragraph 2 is self evident and reflects, inter alia, the principles of pacta sunt servanda, jus cogens, erga omnes.

Mandatory rules

Amendment of Rules

The Special Rapporteur was convinced that such reservations were prohibited only if one acknowledged that jus cogens produced its effect outside the confines of articles 53 and 64 of the Vienna Conventions.

Based in the primacy of the Constitutional rules, all other norms should be non discriminatory.

The Commission has previously resisted the effort of compiling a catalogue of norms of jus cogens and decided to leave the full content of this rule to be worked out in State practice and in the jurisprudence of international tribunals .
