When in the appointment of the Secretary-General it is necessary to choose between two or more persons the following procedures shall be used:
(a) Each principal delegate, or his alternate, of the Members represented in Congress shall be asked to indicate the candidate he prefers by writing the candidate’s name on the voting slip. All candidates who fail to receive a vote and the candidate who receives the smallest number of votes shall be struck from the list of candidates. In the event of two or more candidates receiving the smallest number of votes, a separate vote of preference shall be taken and the candidate who receives the least number of votes shall be eliminated from the list and the other(s) retained. If in this separate vote of preference more than one candidate receives the smallest number of votes, all these candidates shall be eliminated from the list
(b) The procedures described in paragraph (a) shall then be repeated with the reduced list of candidates
(c) This procedure shall continue until one candidate (the “preferred candidate”) remains on the list
(d) A proposal shall then be submitted to Congress that the preferred candidate be declared appointed. Such a proposal shall be supported by a two-thirds majority of the votes cast for and against in order to be adopted
(e) If, at any stage during the voting procedure described in paragraphs (a) to (c) above, a candidate receives a two-thirds majority of the votes cast for and against, he shall be declared appointed and no further votes shall be taken
(f) In the event of the two final candidates in the indication-of-preference procedure receiving the same number of votes, a further vote shall take place
(g) In the event that the proposal described in paragraph (d) is not supported by a two-thirds majority of the votes cast for and against, a further vote shall take place
(h) In the event of the further votes described in paragraphs (f) and (g) being indecisive, Congress shall decide whether further voting shall take place, whether a new procedure shall be followed, or whether its decision shall be withheld.
