Section 26

Each house shall have power to provide for its own safety, and the undisturbed transaction of its business, and may punish, by imprisonment, any person not a member, for disrespectful behavior in its presence; for obstructing any of its proceedings, or any of its officers in the discharge of his duties, or for any assault, threat or abuse of a member, for words spoken in debate. But such imprisonment shall not extend beyond the termination of the session, and shall not prevent the punishment of any offence, by the ordinary course of law.
