Article 40. Amendment of multilateral treaties

  • Chapter
  • First Online:
Vienna Convention on the Law of Treaties

Abstract

Since the end of World War II, the number of multilateral treaties and thus also the complexity of international relations with regard to treaties have increased dramatically. Complexity and fragmentation increase even more when multilateral treaties are amended, ie changed with respect to all the States Parties, or modified, ie altered between certain States Parties only (on the terminology → Art 39 MN 1). Art 40 embodies the basic procedural rules concerning the amendment of multilateral treaties. A specific article with regard to the amendment procedure of bilateral treaties was deemed unnecessary. According to the ILC, the rules contained in Part II suffice in such cases.

    For examples, see UN Handbook on Final Clauses of Multilateral Treaties (2003) 95 et seq. Detailed analyses of the application of specific amendment clauses are provided by MJ Bowman The Multilateral Treaty Amendment Process – A Case Study (1995) 44 ICLQ 540 et seq; AI Sow La spécificité des procédures de révision des traités de l’Organisation mondiale de la propriété intellectuelle (2002) 80 Revue de droit international, des sciences diplomatiques et politiques 169 et seq.

    See eg Art 26 para 2 of the 1979 Convention on the Elimination of All Forms of Discrimination Against Women 1249 UNTS 13, according to which the UN General Assembly shall decide what to do if a States Party proposes an amendment.

  22. 22.

    See eg Art VII of the 1996 Comprehensive Nuclear Test Ban Treaty 35 ILM 1439.

    This is the usual procedure within the IMCO, see AO Adede Amendment Procedures for Conventions with Technical Annexes: The IMCO Experience (1977) 17 VaJIL 201 et seq.

  24. 24.

    See eg Art XIII para 4 of the 1993 Agreement to Promote Compliance with International Conservation and Management Measures by Fishing Vessels on the High Seas 2221 UNTS 120. It is interesting to note that treaties establishing international organizations often allow for majority decisions in amending the treaty, see F Kirgis Specialized Law-Making Processes in O Schachter/C Joyner (eds) United Nations Legal Order (1995) 109, 121 et seq; Bastid (n 3) 175; Grewe (n 18) 980. The specific amendment procedures for treaties establishing international organizations raise many subsequent questions, see eg JA Frowein Are There Limits to the Amendment Procedures in Treaties Constituting International Organisations? in G Hafner et al (eds) Festschrift Seidl-Hohenveldern (1998) 201 et seq; Sienho Yee The Time Limit for the Ratification of Proposed Amendments to the Constitutions of International Organizations 4 Max Planck UNYB 185 et seq.

  25. 25.

    See eg Art 39 para 5 of the 2000 UN Convention Against Transnational Organized Crime 40 ILM 335.

  26. 26.

    See eg Art 109 UN Charter providing for the convening of a revision conference in case of a revision.

  27. 27.

    See eg Art 108 UN Charter according to which amendments are decided by the General Assembly. See also Bastid (n 3) 176 et seq.

  28. 28.

    A different approach is taken by K Ardault/D Dormoy in Corten/Klein Art 40 MN 10 according to whom only States Parties have the right to make an amendment proposal.
