Multilateral treaty
A multilateral treaty is a treaty to which three or more sovereign states are parties. Each party owes the same obligations to all other parties, except to the extent that they have stated reservations. Some examples of multilateral treaties are the Convention Relating to the Status of Refugees, the United Nations Convention on the Law of the Sea, the Geneva Conventions, and the Rome Statute of the International Criminal Court.
