The ICAO Assembly is the Organization’s sovereign body. It meets at least once every three years and is convened by ICAO’s governing body, the Council.
ICAO's 193 Member States and a large number of international organizations are invited to the Assembly, which establishes the worldwide policy of the Organization for the upcoming triennium.
During Assembly Sessions, ICAO’s complete work programme in the technical, economic, legal and technical cooperation fields is reviewed in detail. Assembly outcomes are then provided to the other bodies of ICAO and to its Member States in order to guide their continuing and future work, as prescribed in Article 49 of theConvention on International Civil Aviation
Each Member State is entitled to one vote on matters before the Assembly, and decisions at these Sessions are taken by a majority of the votes cast – except where otherwise provided for in the Convention.
