Our committee chair hasn’t shown up for the meeting, can the meeting still take place?

It is the duty of the chairman to call the committee together, but, if he is absent, or neglects or declines to call a meeting of the committee, it is the duty of the committee to meet on the call of any two of its members. In small special committees the chairman usually acts as secretary, but in large ones and in all standing committees, it is customary to elect a secretary, who keeps a brief memorandum of what is done for the use of the committee. Members of the society have a right to appear at the committee meetings and present their views on the subject before it at such reasonable times as, upon request, the committee may appoint. But during the deliberations of the committee no one has a right to be present, except members of the committee.
