7.—(1) Subject to sub-paragraph (2), no business may be transacted at a meeting of the council unless at least one-quarter of the whole number of members are present.
(2) Where more than one-quarter of the members become disqualified at the same time, then, until the number of members in office is increased to not less than three-quarters of the whole number of members, the quorum of the council is determined by reference to the number remaining qualified instead of by reference to the whole number of members.
