CAT/C/3/Rev.6 If the third ballot is inconclusive, the next ballot shall be restricted to the two candidates who obtained the greatest number of votes in the third ballot and so on, with unrestricted and restricted ballots alternating, until a person or member is elected. 3. If the second ballot is inconclusive and a two-thirds majority is required, the balloting shall be continued until one candidate secures the necessary two-thirds majority. In the next three ballots, votes may be cast for any eligible candidate. If three such unrestricted ballots are inconclusive, the next three ballots shall be restricted to the two candidates who obtained the greatest number of votes in the third such unrestricted ballot, and the following three ballots shall be unrestricted, and so on until a person or member is elected. Rule 60 Conduct of elections when two or more elective places are to be filled When two or more elective places are to be filled at one time under the same conditions, those candidates obtaining in the first ballot the majority required shall be elected. If the number of candidates obtaining such majority is less than the number of persons or members to be elected, there shall be additional ballots to fill the remaining places, the voting being restricted to the candidates obtaining the greatest number of votes in the previous ballot, to a number not more than twice the places remaining to be filled; provided that, after the third inconclusive ballot, votes may be cast for any eligible candidates. If three such unrestricted ballots are inconclusive, the next three ballots shall be restricted to the candidates who obtained the greatest number of votes in the third of the unrestricted ballots, to a number not more than twice the places remaining to be filled, and the following three ballots thereafter shall be unrestricted, and so on until all the places have been filled.
