It may punish or expel any member for disorderly conduct or violation of its rules, and declare his seat vacant for absence without valid excuse, where such absence has continued for two months. No expulsion shall take place without the concurrence of two thirds of all the members elected, and until the delinquent member has been notified of the charge against him and has had an opportunity to be heard.
