According to Article 149 of the Constitution, the Constitutional Court consists of two sections and a plenary assembly. The sections convene under the chairmanship of the deputy president with the participation of four members. The plenary assembly shall convene with the participation of at least twelve members under the chairmanship of the President of the Constitutional Court or a deputy president determined by the President. The sections and the plenary assembly shall take decisions by absolute majority. Commissions may be established to examine the admissibility of the individual applications.

It is within the competence of the plenary assembly to hear the cases and applications concerning political parties, actions for annulment and objection and trials where it acts as the Grand Tribunal. The sections are endowed with the power to decide principally on merits of individual applications and on admissibility in some exceptional cases. The commissions are solely responsible for decisions of admissibility of individual applications.

In order to decide for the annulment of a constitutional amendment, dissolution of political parties or their deprivation from state aid, two thirds majority of members attending the meeting is required.

The Constitutional Court examines cases on the basis of documents in the case file, except where it acts as the Grand Tribunal. Nonetheless, it may decide to hold a hearing for individual applications. When it deems necessary, the Court also may call on those concerned and those having knowledge relevant to the case, to present oral explanations.  The Constitutional Court, in cases relating to dissolution of a party, shall also hear the defense of the chairman of the party whose dissolution is in process or of a proxy appointed by the chairman, after the Chief Public Prosecutor of the Court of Cassation.
