[157] Cl15.6 of the Rules makes clear that, if an appeal against a decision of the Committee under cl15.4 is lodged, the decision of the Committee is to be of no effect unless and until a general meeting confirms the resolution. This shows, in my view, that the general meeting has full power to decide matters of both guilt and penalty. If an appeal is lodged, the rules themselves provide that there is no effective resolution of expulsion or suspension until that appeal is dealt with. As a matter of construction, and bearing in mind s18(3) of the Act, it seems to me that the right of appeal to the general meeting is conferred in relation to not only valid decisions of the Committee under cl15.4, but also in relation to purported decisions of the Committee under cl15.4. If there had been a breach of natural justice in the decisions of the Committee, concerning some matter which the rules, properly construed, required to happen, those decisions would be, for that reason, defective decisions, but not (because of s18(3)) invalid. Even though they were defective, they would be purported decisions of the Committee. When there is an appeal instituted, within the confines of the rules, against such a purported decision, and the General Meeting acting in accordance with the rules decides to confirm the expulsion, that expulsion is effective."
