• B2.1 Scientific Matters
  • B2.11 Recommendations of a scientific nature received from Divisions, or other bodies of the Union, shall be the responsibility of the Council. The Council may adopt them by a simple majority of personal votes cast by the Delegates present at a regular meeting. Between such meetings, the Bureau may act on behalf of the Council in these matters. The Bureau shall establish procedures for approval of recommendations in nomenclature, symbols, terminology, and conventions.
  • B2.12 Postal and electronically submitted ballots on scientific matters may be conducted in accordance with a procedure to be determined by the Bureau for each ballot.
  • B2.2  Nonscientific Matters Voting on nonscientific matters shall be by Delegations, each Delegation being entitled to cast the number of assigned votes. All the votes to which the Adhering Organization is entitled shall be cast in the same sense.
  • B2.21 Admission and Removal of Members
    Admission of Members shall be by a simple majority of votes recorded at a regular meeting of the Council. Removal of an Adhering Organization shall be valid only if at least three-quarters of the votes recorded at a regular meeting of the Council are cast in favor of such removal. Any reassignment approved by the Council shall become effective on 1 January of the following year.
  • B.2.22 Elections
    For election of Officers of the Union and Elected Members of the Bureau the following rules shall apply:
  • B2.221 Nominations may be made by the Adhering Organizations. These nominations must be received in writing by the Secretary General via the Secretariat at least two months before the beginning of the meeting of the Council at which the elections will take place. They must indicate clearly the position for which each candidate is nominated and shall be accompanied by a biographical note on each candidate.
  • B2.222 The Bureau shall discuss the nominations made by the Adhering Organizations at a meeting prior to the meeting of the Council at which the elections are to take place. It has the right to make additional nominations for which information shall be provided. When the number of nominations exceeds the number of vacancies, the Bureau may make recommendations to the Council for filling the vacancies. These recommendations are not binding on the Council.
    • The officers of the Union and the Elected Members of the Bureau, as defined by the Statutes, shall be elected at a regular meeting of the Council by a written  and secret ballot, a simple majority of the votes recorded being required for election. The election for each officer shall be held separately. If no nominee receives a majority on the first ballot, the nominee receiving the smallest number of votes shall be eliminated from the next ballot and successive ballots shall be held until a nominee receives a simple majority of the votes recorded or there are only two nominees on which to vote. If two nominees get an equal number of votes, the Presiding Officer, after consultation with the Executive  Committee, shall cast the deciding vote.
    • For election of Elected Members of the Bureau, the nominees receiving the highest number of votes shall be elected to the vacancies, provided that the number of votes cast for each such nominee shall be a majority of the total votes cast per vacancy. If fewer nominees than the vacancies receive a majority of such votes cast, then those receiving a majority shall be declared elected and a second ballot conducted among the remaining nominees for the remaining vacancies. If, in this second ballot, no nominee receives a majority, the nominee receiving the smallest number of votes shall be eliminated from the next ballot and successive ballots conducted until all vacancies are filled. In each ballot, the number of names on ballot papers submitted by each Delegation shall be no more and no less than the number of vacancies outstanding at the conclusion of the previous ballot.
  • B2.23 Other Nonscientific Matters
    • Proposals on other nonscientific matters, after consideration, may be adopted without a formal vote unless objections are raised, when a vote shall be taken. Unless specifically stipulated otherwise in the Statutes and Bylaws, a simple majority of the votes recorded shall be required for adoption.
  • B2.24 Postal and Electronically Transmitted Ballots
    • Postal and electronically transmitted ballots on nonscientific matters may be conducted in accordance with a procedure described below, each Adhering Organization being entitled to cast the number of assigned votes, provided always that decisions on admission and removal of Members [(B2.21) above] and elections [(B2.22) above], the location of the official headquarters of the Union, changes in Statutes and Bylaws, and the dissolution of the Union are excluded from such postal and electronically transmitted ballots. Decisions reached by postal and electronically submitted ballot on nonscientific matters shall be subject to ratification by the Council at its next meeting. In postal and  electronically submitted ballots on nonscientific matters, only those votes shall be valid which are received within four months from the date of mailing of the request for voting. Action shall only be taken if more than one-half of the maximum possible number of votes has been received at that date. A simple majority of the votes shall be required for a decision.
  • B2.25 Additions to Council Agenda
    • Matters to be considered at a meeting of the Council must appear on the agenda of that meeting, which shall be sent to the Adhering Organizations at least four months before the meeting is to be held. However, in case of urgency, a question may be added to the agenda with the consent of at least three-quarters of the Delegates present at the meeting. Modification of the Statutes or Bylaws, admission or removal of Members, and elections of Officers or Elected Members of the Bureau, are excluded from this procedure.
