Serjeant-at-Arms
The Serjeant-at-Arms is the officer of Parliament who has the duty of maintaining order in the precincts of the House. For instance, if the conduct of any MP is grossly disorderly during a sitting of Parliament, the Speaker or a committee chairman may order him or her to withdraw immediately from Parliament for the rest of the day's sitting, and the Speaker or chairman may instruct the Serjeant to enforce the order. The Speaker may also direct an MP to withdraw when Parliament has voted to suspend him or her for committing the offence of disregarding the authority of the Chair or of persistently and wilfully obstructing the business of Parliament. If the MP refuses to obey this direction despite having been summoned several times to do so by the Serjeant acting under the Speaker's orders, the Serjeant may use force to compel the MP's obedience to the direction.
The Serjeant-at-Arms is also the custodian of the Mace of Parliament, and bears the Mace into and out of the chamber of the House – the room where Parliamentary debates take place – during sittings (see below).
