Article 37 Participation in cases of separation of parts of a State in treaties signed by the predecessor State subject to ratification, acceptance or approval

Subject to paragraphs 2 and 3, if before the date of the succession of States the precedessor State had signed a multilateral treaty subject to ratification, acceptance or approval and the treaty, if it had been in force at that date, would have applied in respect of the territory to which the succession of States relates, a successor State falling under article 34, paragraph 1, may ratify, accept or approve the treaty as if it had signed that treaty and may thereby become a party or a contracting State to it.

Paragraph 1 does not apply if it appears from the treaty or is otherwise established that the application of the treaty in respect of the successor State would be incompatible with the object and purpose of the treaty or would radically change the conditions for its operation.

If the treaty is one falling within the category mentioned in article 17, paragraph 3, the successor State may become a party or a contracting State to the treaty only with the consent of all the parties or of all the contracting States.
