Intergovernmental organizations in a legal sense should be distinguished from simple groupings or coalitions of states, such as the G7 or the Quartet. Such groups or associations have not been founded by a constituent document and exist only as task groups. Intergovernmental organizations must also be distinguished from treaties. Many treaties (such as the North American Free Trade Agreement, or the General Agreement on Tariffs and Trade before the establishment of the World Trade Organization) do not establish an organization and instead rely purely on the parties for their administration becoming legally recognized as an "ad hoc" commission. Other treaties have established an administrative apparatus which was not deemed to have been granted international legal personality.
