Find out more about the Joint Protocol on the Implementation of the Vienna Agreement and the Paris Agreement on our website on multilateral agreements. The Convention codifies several foundations of contemporary international law. It defines a treaty as “an international agreement concluded in writing between States and subject to international law” and reaffirms that “each State has the capacity to conclude treaties”. Article I limits the application of the Convention to written treaties between States and excludes treaties concluded between States and international organizations or international organizations themselves. Article 26 defines pacta sunt servanda, article 53 proclaims the peremptory norm and article 62 proclaims the fundamental change of circumstances. It was adopted on 27 The Governing Body of CEN, meeting in Geneva on 16 and 17 May 1991 on 16 June 1991 in Vienna, was formally approved by the Governing Body of CEN, following its approval by the ISO Executive Board on 16 and 17 May 1991, and replaced the 1989 Agreement on the exchange of technical information between ISO and CEN (Lisbon Agreement). The “codified” Viennese agreement was approved in 2001 by the ISO Council and the CEN Board of Directors. The Convention applies only to written treaties between States. The first part of the document defines the terms and scope of the agreement. Part Two sets out the rules governing the conclusion and acceptance of contracts, including the agreement of the parties to the contractual obligation, and the formulation of reservations and reservations, i.e. the refusal to bind to one or more specific provisions of a contract, while accepting the rest. The third part deals with the application and interpretation of treaties and the fourth part deals with the possibilities of amending or amending treaties. These parts essentially codify existing customary law.
The most important part of the Convention, Part V, describes the grounds and rules for the cancellation, termination or suspension of contracts and contains a provision that confers jurisdiction on the International Court of Justice to rule on disputes relating to the application of those rules. The latter parts discuss the impact of changes of government within a State, changes in consular relations between States and the outbreak of hostilities between States on treaties, as well as rules on depositaries, registration and ratification. However, agreements between States and international organizations or between international organizations themselves are governed by the 1986 Vienna Convention on the Law of Treaties between States and International Organizations or between International Organizations when it enters into force. In addition, the provisions of the Convention among the Members of the State continue to apply in treaties between States and international organizations.  The Convention does not apply to un written agreements.
