Firstly: The Supreme Council is the highest authority of the GCC formed of the Heads of Member States. Its presidency rotates according to the Arabic alphabetical order of the names of Member States. It convenes one regular session every year. However, extraordinary sessions may be convened at the request of any Member State seconded by another. In 1998, during the 19th summit held in Abu Dhabi, the Supreme Council decided to hold a consultative meeting in between two summits every year. Meetings of the Supreme Council are considered valid if attended by two-thirds of the Member States, at which each has one vote. Resolutions on substantive matters are issued by unanimous approval of the members present, while a majority is enough to approve those of procedural nature.

[GCC Charter] The Consultative Commission: Formed of thirty GCC citizens (five from each Member States) chosen according to their experience and qualification for a period of three years. The Consultative Commission is charged with studying matters referred to it by the Supreme Council. [CC Regulation]

Commission for the Settlement of Disputes: Formed by the Supreme Council for every case on an ad-hoc basis in accordance with the nature of the dispute.

Secondly: The Ministerial Council is composed of the Ministers of Foreign Affairs or other ministers acting on their behalf. Presidency of the Ministerial Council is entrusted with the Member State that presided the last ordinary session of the Supreme Council, or when necessary, with the Member State that is next to preside the Supreme Council. The Ministerial Council convenes every three months, and may hold extraordinary meetings upon the request of one Member State seconded by another.
A meeting is considered valid if attended by two-thirds of the Member States.

Among other jurisdictions, the Ministerial Council is authorised to propose policies, lay out recommendations, and encourage and coordinate the already existing activities in all fields. Resolutions adopted by other ministerial committees are referred to the Ministerial Council, which in turn would refer the relevant matters, along with appropriate recommendations, to the Supreme Council for approval. The Ministerial Council is also charged with arranging the Supreme Council meetings and preparing their agenda. Procedures of voting are similar to those applicable at the Supreme Council. [GCC Charter]
