Challenges are referred to the judicial court by means of a petition.
Where the dispute relates to the electorate, the application is only admissible if it is delivered or sent within three days of publication of the electoral roll.
Where the challenge relates to a decision of the administrative authority, at the request of the court registry, the latter must provide proof that it has served notice of its decision on the court seised or, failing this, that it has received the challenge. If the court so requests, it must provide all the information specifying the legal or factual grounds on which its decision was based.
Where the dispute relates to the regularity of the election or appointment of trade union representatives, the application is only admissible if it is submitted or sent within fifteen days of the election or appointment.
