About the Assembly
ICAO has a sovereign body, the Assembly, and a governing body, the Council.
The Assembly meets at least once every three years and is convened by the Council. ICAO's 190 Member States and a large number of international organizations are invited to the Assembly, which will establish the worldwide policy of the Organization for the next three years.
At these sessions, the complete work of the Organization in the technical, economic, legal and technical cooperation fields is reviewed in detail, and guidance is given to the other bodies of ICAO for their future work as prescribed in Article 49 of the Convention on International Civil Aviation.
Each Contracting State is entitled to one vote, and decisions of the Assembly are taken by a majority of the votes cast except when otherwise provided for in the Convention.
