39. It is also a breach of decorum for a member to come into the assembly room with his head covered, or to remove from one place to another with his hat on, or to put his hat on in coming in or removing, or until he has taken his seat; and, in many assemblies, especially those which consist of a small number of members, it is not the custom to have the head covered at all.
40. In all instances of irregular and disorderly deportment it is competent for every member, and is the special duty of the presiding officer, to complain to the assembly, or to take notice of the offence, and call the attention of the assembly to it. When a complaint of this kind is made by the presiding officer, he is said to _name_ the member offending; that is, he declares to the assembly, that such a member, calling him by name, is guilty of certain irregular or improper conduct. The member, who is thus charged with an offence against the assembly, is entitled to be heard in his place in exculpation, and is then to withdraw. Being withdrawn, the presiding officer states the offence committed, and the assembly proceeds to consider of the degree and amount of punishment to be inflicted. The assembly may allow the member complained of to remain, when he offers to withdraw; or, on the other hand, it may require him to withdraw, if he do not offer to do so of his own accord. The proceedings are similar, when the complaint is made by a member, except that the offence is stated by such member, instead of being stated by the presiding officer.
41. No member ought to be present in the assembly, when any matter of business concerning himself is debating; nor, if present, by the indulgence of the assembly, ought he to vote on any such question. Whether the matter in question concern his private interest, or relate to his conduct as a member,—as for a breach of order, or, for matter arising in debate,—as soon as it is fairly before the assembly, the member is to be heard in exculpation and then to withdraw, until the matter is settled. If, notwithstanding, a member should remain in the assembly and vote, his vote may and ought to be disallowed; it being contrary, not only to the laws of decency, but to the fundamental principle of the social compact, that a man should sit and act as a judge in his own case.
