Artikel 33

1. Subject to paragraphs 2 and 3, if before the date of the succession of States one of the predecessor States had signed a multilateral treaty subject to ratification, acceptance or approval, a successor State falling under article 31 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.
2. 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.
3. 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.
4. Any treaty to which the successor State becomes a party or a contracting State in conformity with paragraph 1 shall apply only in respect of the part of the territory of the successor State in respect of which the treaty was signed by one the predecessor States unless:
(a) in the case of a multilateral treaty not falling within the category mentioned in article 17, paragraph 3, the successor State when ratifying, accepting or approving the treaty gives notice that the treaty shall apply in respect of its entire territory;
(b) in the case of a multilateral treaty falling within the category mentioned in article 17, paragraph 3, the successor State and all the parties or, as the case may be, all the contracting States otherwise agree.
5. Paragraph 4(a) does not apply if it appears from the treaty or is otherwise established that the application of the treaty in respect of the entire territory of the successor State would be incompatible with the object and purpose of the treaty or would radically change the conditions for its operation.
