First, I would note that even a motion that commends someone may insult and/or defame a member. If a main motion is adopted, "That Gary be commended on the professional way he manages his prostitution ring," you might regard that defamatory, even though the assembly represents this as a favorable opinion of you. If inflicted as a result of disciplinary action, it is a form of punishment. If adopted as merely the opinion of the assembly, it is not a punishment and does not require due process. See p. 137, l. 20 ff., for an example of a motion to censure that is not disciplinary action. I would also refer you to: Censure: Penalty verses Motion, Parliamentary Journal, April 2012
