In each list where one or several candidates are elected compliant to article 172, the substitute candidates with the highest number of votes are declared first, second, third substitute, and so on. If there is equality, the substitutes are declared first, second, third and so on, following the order of the presentations.

In advance of their appointment, the central committee having chosen the incumbents, continues with the individual attribution to the substitute candidates of half of the number of ballot papers in following the order of presentation of these candidates. This half is establish by dividing the total number of ballots by two, compliant to article 156, § 1er, sentence 2, 1° and 2°.

The attribution of these ballots follows a devolutif mode. They are added to the nominative votes obtained by the first substitute candidate in concurrence to what is needed to reach the eligibility number mentioned in article 172, sentence 3. The remaining votes, if there are any, are attributed in a similar procedure to the second substitute candidate, then to the third, and so on, following the order of the presentation until half of ballot papers in favor of the order of the presentation of the candidates, are distributed.
