If a member of the National Council ceases to hold office for any reason whatsoever before the expiry of his normal term of office, he shall be replaced within three months by the first non-elected candidate on the list. If there are no further non-elected candidates on the list, an election shall be held by the college to which the member concerned belonged, by a majority vote in a single ballot.
In all cases, the duties of the new member shall expire on the date on which those of the member he replaces would have ended. If the term of office is less than two years, the person concerned is eligible for election for a period of four years immediately renewable for an equal period.
