The Constitutional Council sees to and decides when it is referred to a matter:
• on the constitutionality of the laws before their promulgation;
• on the constitutionality of the internal regulations of the Senate and of the Chamber of Deputies before their implementation
• on the orders
For the same purposes, the laws in general may be referred to the Constitutional Council, before their promulgation, by the President of the Republic, the President of the Senate, the President of the Chamber of Deputies, a group of fifteen (15) Deputes or of (10) Senators.
The law determines the modalities of organization and of functioning of the Constitutional Council as well as the other entities enabled to refer a matter to it. (Art. 190ter-5)
