What are the "Vienna formula" and the "All states formula"?
Last Updated: Apr 27, 2018
These are terms used in treaty practice and concern which states may become party to a multilateral treaty deposited with the Secretary-General of the United Nations. These formulas were developed to help the Secretary-General determine if an entity could be considered a state for the purposes of a convention when there was political opposition to recognition of the state.
A detailed explanation is given in the Summary of Practice of the Secretary-General as Depositary of Multilateral Treaties, paragraph 79, available on the United Nations Treaty Collection website.
"Vienna Formula" is a reference to Part VIII: Final Provisions section of the 1969 Vienna Convention on the Law of Treaties.
