ARTICLE 34
The National Assembly has the right, and, on proposal of one-fifth of its members, the duty to appoint committees of investigation. These committees, in public sittings, inquire into the evidence which they, or the proponents, consider necessary. The public may be excluded by a two-thirds vote of the committee of investigation. The rules of procedure regulate the proceedings of the committee and determine the number of its members.
The judicial and administrative authorities are required to comply with requests by these committees for information, and the record of the authorities shall on request be submitted to them.
The provisions of the code of criminal procedure apply as far as is suitable to the inquiries of these committees and of the authorities assisting them, but the secrecy of letter and other post, telegraph, and telephone services will remain inviolate.
