Treaties

Common Treaty Format

Modern treaties typically are negotiated between plenipotentiaries, and the terms, often drafted by legal experts, are recorded in written texts or documents. The negotiation and signing of treaties is normally associated with pomp and ceremony, and the protocols and texts follow a general template. The preamble provides the names and affiliations of the contracting parties and is a statement of the treaty's general objectives. This is usually followed by the articles containing the agreed-on stipulations. If the treaty is concluded for a definite period, a statement of that time frame follows; or, if it is in perpetuity, there may be a provision inserted that either party may “denounce” (i.e., give notice to terminate) the treaty. Any reservations that alter the treaty's provisions for the concerned state may then appear; they are followed by an article that provides for the treaty's ratification and for the time and place for the exchange of ratifications. Treaties usually end with a clause stating that “in witness whereof the respective plenipotentiaries have affixed their names and seals,” below which are the signatures and indications of the location and the date. “Additional articles” often are appended and signed by the plenipotentiaries, with the declaration that they have the same force and value as if they had been included in the body of the treaty or convention.

A country's signature is often sufficient to manifest its intention to be bound by the treaties, although, in certain circumstances, treaties have to be ratified by domestic plebiscite. Treaties are expected to be executed in good faith, in keeping with the principle of pacta sunt servanda (Latin: “agreements must be kept”), arguably the oldest principle of international law. Without this principle, which is explicitly mentioned in many agreements, treaties would be neither binding nor enforceable. The international rules concerning treaties between states are contained in the Vienna Convention on the Law of Treaties (1969), and those between states and international organizations appear in the Vienna Convention on the Law of Treaties Between States and International Organizations or Between International Organizations (1986). The UN Charter states that treaties must be registered with the United Nations to be invoked before it or enforced in its judiciary organ, the Court of Justice. This was designed primarily to prevent the proliferation of secret treaties such as those that occurred in the 19th and 20th centuries. The charter also states that its members' obligations under it outweigh any competing obligations under other treaties. After their adoption, treaties, as well as their amendments, have to follow the official legal procedures of the United Nations, as applied by the Office of Legal Affairs, including signature, ratification, and entry into force.
