A reservation is a declaration by a State purporting to exclude or modify the legal effects of certain provisions of the Treaty in their application to that State. A reservation allows a State to accept a multilateral treaty as a whole by giving it the option of not applying certain provisions that it does not wish to comply with. Reservations may be made once the treaty has been signed, ratified, accepted, approved or acceded to. Bookings must not be incompatible with the purpose and purpose of the contract. In addition, a treaty may prohibit reservations or authorize only certain reservations. After the conclusion of a contract, written documents formally proving consent to the link, as well as reservations and declarations, shall be placed in the custody of a depositary. Unless otherwise provided in the Treaty, the deposit of instruments of ratification, acceptance, approval or accession requires the consent of a State to be bound by it. In the case of contracts concluded with a small number of parties, the depositary is generally the Government of the State in whose territory the contract was signed. Sometimes different States are chosen as depositaries. Multilateral treaties generally designate an international organization or the Secretary-General of the United Nations as depositary. The depositary must receive all notifications and documents relating to the contract, verify that all formal requirements have been met, file them, register the contract and notify the parties concerned of all relevant documents.
Accession is the act by which a State which has not signed a treaty may express its consent to be bound by that treaty. However, accession to a treaty is possible only if the treaty so provides or if all contracting parties subsequently agree that consent to be bound by the treaty may be expressed by a State by accession. In such cases, accession has the same legal effect as ratification. Multilateral treaties are agreements between more than two parties. They are often the result of an international conference or meeting of nations held under the auspices of an international organization. Instruments of “acceptance” or “approval” of a treaty have the same legal effect as ratification and therefore express the consent of a State to be bound by a treaty. In the practice of some States, acceptance and consent have been used instead of ratification when constitutional law at the national level does not require ratification by the head of State. `Acceptance` means the formal act defining the form and content of a proposed text of the Treaty. As a general rule, the text of the treaty is adopted with the consent of the States involved in the treaty-making process. Treaties negotiated within an international organization are normally adopted by decision of a representative organ of the organization whose membership is more or less equal to the possible participation in the treaty in question.
A treaty may also be adopted by an international conference convened specifically for the elaboration of the treaty, with a two-thirds vote of the States present, unless they have decided, by the same majority, to apply a different rule. As a rule, the provisions of the contract determine the date on which the contract enters into force. If the treaty does not specify a date, there is a presumption that the treaty will enter into force as soon as all the negotiating States have agreed to be bound by the treaty. Bilateral treaties may provide for their entry into force on a specified date, on the date of their last signature, on the exchange of instruments of ratification or on the exchange of notifications. In the case of multilateral treaties, it is customary to provide for a fixed number of States to express their consent to entry into force. Some treaties provide for additional conditions that must be met, for example by stipulating that a certain category of States must be among those willing to give their consent. The treaty may also provide for additional time to elapse after the required number of countries have expressed their consent or the conditions have been met. A treaty enters into force for States that have given the necessary consent. A treaty may also provide that, under certain conditions, it enters into force provisionally. Accession is an act by which a State expresses its consent to be legally bound by the provisions of a particular treaty. Here, the State accepts the possibility or offer to become a party to a treaty that is already being negotiated and signed by other States.
This usually happens after the entry into force of the treaty. Accession is therefore not preceded by an instrument of signature. However, accession has the same legal effect as ratification. The formal accession procedure is governed by the national legislation of the State. The term “act of formal confirmation” is used as an equivalent to the term “ratification” when an international organization expresses its consent to be bound by a treaty.
