Primary Sources of International Law
The Restatement Third defines a treaty as, "an agreement between two or more states or international organizations that is intended to be legally binding and is governed by international law;" Treaties can take the form of Bilateral (two party) or Multilateral (multi- party) treaties. Terms such as agreement, charter, convention, covenant, and protocol are often used interchangeably with the term "treaty."
