||Final clauses are provisions typically found at the end of a treaty, dealing with such topics as signature, ratification, acceptance, approval, accession, denunciation, amendment, reservation, entry into force, settlement of disputes, depositary matters and authentic texts.
In the case of multilateral treaties to be deposited with the Secretary-General, parties should submit for review draft final clauses to the Treaty Section well in advance of the adoption of the treaty (see section 6.5).
||instrument of full powers
Full powers take the form of a solemn instrument issued by the Head of State, Head of Government or Minister for Foreign Affairs, empowering a named representative to undertake given treaty actions (see annex 3).
The Secretary-General's practice in relation to full powers may differ in certain respects from that of other depositaries. The Secretary-General does not accept full powers transmitted by telex or powers that are not signed.
The Head of State, Head of Government and Minister for Foreign Affairs are considered as representing their State for the purpose of all acts relating to the signature of, and the consent to be bound by, a treaty. Accordingly, they need not present full powers for those purposes.
See articles 2(1)(c) and 7 of the Vienna Convention 1969. instrument of general full powers
An instrument of general full powers authorises a named representative to execute certain treaty actions, such as signatures, relating to treaties of a certain kind (for example, all treaties adopted under the auspices of a particular organization).
|memorandum of understanding (M.O.U.)
||The term memorandum of understanding (M.O.U.) is often used to denote a less formal international instrument than a typical treaty or international agreement. It often sets out operational arrangements under a framework international agreement. It is also used for the regulation of technical or detailed matters. An M.O.U. typically consists of a single instrument and is entered into among States and/or international organizations. The United Nations usually concludes M.O.U.s with Member States in order to organize its peacekeeping operations or to arrange United Nations conferences. The United Nations also concludes M.O.U.s regarding cooperation with other international organizations. The United Nations considers M.O.U.s to be binding and registers them if submitted by a party or if the United Nations is a party.
