  1. Procedure
    1. Nominations
      1. A call for nominations to Commissions and the Council shall be sent to all Liaison Committees and Commissions at least six months before a General Assembly.
      2. Nominations from Liaison Committees must be received by the Secretary-General no later than four months before a General Assembly. Nominations from Commissions must be received no later than six weeks before a General Assembly. A statement of the candidate's qualifications sufficient to allow an evaluation of the candidate must accompany nominations. It is preferred that nominations be submitted electronically.
      3. The Council will prepare a slate of nominees for the Commissions and Council from the nominations and may itself suggest names (in which case a statement of qualifications will be prepared). Special consideration will be given to continuity, geographic distribution, and coverage of major sub-fields within the Commissions. Delegates will receive the slate of nominees at the start of the General Assembly.
      4. Liaison Committees may resubmit nominations at the General Assembly of persons not on the Council's slate, but these renominations must be supported by at least one other delegation. The Council then will prepare a final ballot with its recommendations and list any renominations for a position.
      5. It may be necessary because of unforeseen circumstances, such as the unavailability of a candidate, to make nominations at the General Assembly. If so, nominations can be made by the Heads of Delegations, Commission Chairs, or Members of the Council. Such nominations require a seconder.

      1. If more names are included on the final ballot than there are positions, the election will be by secret ballot. Each Delegation Head will vote its block of votes.
      2. Two tellers appointed by the General Assembly count votes. Assistance may be provided, if desired, by Secretariat personnel
