There is no doubt that in a democratic and representative system a parliamentary mandate cannot last forever. Every mandate, including the one of president of the standing bureau, supposes a limited duration in time. It also presupposes the possibility to be revoked. A recent political dispute, with legal consequences, brought into attention the revoking of the mandate of speaker of a House of Parliament. Constitutional provisions and Standing Orders of the Houses can be interpreted in either way. For the future, this paper suggests a general prescription at constitutional level, which should leave more room for details at the level of Standing Orders, as to alleviate parliamentary debates of purely organisational matters and allow the representative assembly to concentrate more on its specific and much more important functions.
