Paragraph 1
The chairman or, in his absence, the vice-chairman may call a meeting of the Board at any time.
If a requisition for a meeting, signed by at least five members, is presented to the chairman and the chairman either—
refuses to call a meeting; or
without so refusing, does not within seven days after the requisition has been presented to him call a meeting,
those members may forthwith call a meeting.
Before each meeting of the Board, a notice of the meeting which—
specifies the business proposed to be transacted at it, and
is signed by the chairman or by an officer (other than the chief officer of the Board) authorised by the chairman to sign on his behalf,
shall be delivered to each member, or sent by post to his last-known address, at least seven clear days before the day of the meeting.
Lack of service of the notice on any member shall not affect the validity of a meeting.
In the case of a meeting called by the members in default of the chairman, the notice shall be signed by the members and no business shall be transacted at the meeting other than that specified in the notice.
