Section 12

Each house shall have the power to determine the rules of its proceedings; and punish its members or other persons for con tempt or disorderly behaviour in its presence; enforce obedience to its process; to protect its members against violence or offers of bribes or private solicitations; and, with the concurrence of two-thirds, expel a member, but not a second time for the same cause. A member expelled for corruption shall not thereafter be eligible to either house; and punishment for contempt or disorderly behavior shall not bar an indictment for the same offense. Each house shall keep a journal of its proceedings and from time to time publish the same, except such parts as require secrecy; and the yeas and nays on any question shall, at the desire of any five members, be entered on the journals.
