Article 69

Each Chamber shall establish and vote its rules of procedure. However, they may not be applied until the Constitutional Court has declared them consistent with the provisions of this Constitution. The two Chambers of Parliament shall, when drafting their respective rules of procedure, take into consideration the requirements of their harmonisation and complementarity, so as to guarantee the efficiency of parliamentary work. The rules of procedure shall set out in particular: - the rules of composition, functioning and membership concerning parliamentary groups and groupings, and the specific rights recognised for opposition groups; - the obligation of effective participation of members in the work of committees and plenary sittings, including the sanctions applicable in the event of absence; - the number, powers and organisation of the standing committees, reserving the chairmanship of at least one or two of these committees for the opposition, subject to the provisions of Article 10 of this Constitution.
