||Modification, in the context of treaty law, refers to the variation of certain provisions of a treaty only as between particular parties to that treaty. As between other parties, the original provisions apply. If a treaty is silent as to modifications, they are allowed only to the extent that they do not affect the rights or obligations of the other parties to the treaty and do not contravene the object and purpose of the treaty. See article 41 of the Vienna Convention 1969.
||The Monthly Statement is the statement published by the United Nations Secretariat on a monthly basis detailing the treaties and international agreements registered or filed and recorded during the preceding month (see section 5.7.4).
||A party to a treaty is a State or other entity with treaty-making capacity that has expressed its consent to be bound by that treaty by an act of ratification, acceptance, approval or accession, etc., where that treaty has entered into force for that particular State. This means that the State is bound by the treaty under international law. See article 2(1)(g) of the Vienna Convention 1969.
