Chapter XVII: Section XV: Order

$Each House may determine the rules of its proceedings; punish its members for disorderly behavior, and, with the concurrence of two-thirds, expel a member.--_Const._ I. 5.$

In Parliament, "instances make order," _per Speaker Onslow_, 2 _Hats._ 144; but what is done only by one Parliament, cannot be called custom of Parliament: _by Prynne_, 1 _Grey_, 52.
