Composition and delegations
Each Member State sends a delegation, led by a head of delegation authorized to vote. The size of the delegation is unrestricted, but only one vote is cast per State.
Observers, whether international organizations or candidate States, may attend public sessions without the right to vote.



Powers
The Assembly defines the general guidelines, adopts the budget, elects the members of the Executive Council and the Secretary-General, admits new States and may suspend a member.
It also adopts binding directives, after examination by the competent committee and the opinion of the Executive Council.
Voting rules
Practice favors consensus. Failing that, ordinary decisions are taken by simple majority of the States present and voting. Major questions require a two-thirds majority.
Voting is by show of hands, or by secret ballot for elections and at the request of a delegation supported by several others.
Conduct of a session
A session comprises an opening ceremony, plenary meetings, regional group meetings and a closing meeting. The Secretary-General presents his or her report, and the chair of the Council reports on the work of the executive.
Proceedings are conducted in the three official languages, with simultaneous interpretation.
