1. The members of the Court shall be elected for nine years and may be re-elected; provided, however, that of the judges elected at the first election, the terms of five judges shall expire at the end of three years and the terms of five more judges shall expire at the end of six years. 2. The judges whose terms are to expire at the end of the above-mentioned initial periods of three and six years shall be chosen by lot to be drawn by the SecretaryGeneral immediately after the first election has been completed. 3. The members of the Court shall continue to discharge their duties until their places have been filled. Though replaced, they shall finish any cases which they may have begun. 4. In the case of the resignation of a member of the Court, the resignation shall be addressed to the President of the Court for transmission to the Secretary-General. This last notification makes the place vacant. Article 14 Vacancies shall be filled by the same method as that laid down for the first election, subject to the following provision: the Secretary-General shall, within one month of the occurrence of the vacancy, proceed to issue the invitations provided for in Article 5, and the date of the election shall be fixed by the Security Council. Article 15 A member of the Court elected to replace a member whose term of office has not expired shall hold office for the remainder of his predecessor's term. Article 16 1. No member of the Court may exercise any political or administrative function, or engage in any other occupation of a professional nature. 2. Any doubt on this point shall be settled by the decision of the Court.
