(d) An instrument appointing a proxy, attorney or representative may direct the manner in which the proxy, attorney or representative is to vote in respect of a particular resolution. Where an instrument contains such a direction, the proxy, attorney or representative is not entitled to vote on the proposed resolution except as directed in the instrument. (e) Subject to rule 13.10(f), an instrument appointing a proxy, attorney or representative need not be in any particular form as long as it is in writing, legally valid and executed by the appointer or the appointer’s attorney. (f) A proxy, attorney or representative may not vote at a General Assembly meeting or adjourned meeting or on a poll unless the instrument appointing the proxy, attorney or representative, and the authority under which the instrument is signed or a certified copy of the authority, are received in the places or at the fax numbers or by email, and before the times, specified for that purpose in the notice calling the meeting. In the notice: (1) the place may be the Forum’s registered office or another place, a fax number may be the fax number at the Forum’s registered office or another fax number, and an email address may the email of the Forum or another email address; and (2) the time may be before the time for holding the meeting or adjourned meeting. (g) The Forum councillors may waive all or any of the requirements of rules 13.10(e) and (f) and in particular may, on production of any other evidence the Forum councillors require to prove the validity of the appointment of a proxy or attorney, accept: (1) an oral appointment of a proxy, attorney or representative; (2) an appointment of a proxy, attorney or representative which is not signed or executed in the manner required by rule 13.10(e); or (3) the deposit, tabling or production of a copy (including a copy sent by fax or email) of an instrument appointing a proxy, attorney or representative, or of the power of attorney or other authority under which the instrument is signed. (h) A vote given in accordance with the terms of an instrument appointing a proxy, attorney or representative is valid despite the revocation of the instrument, or of the authority under which the instrument was executed, if the Forum has not received written notice of revocation by the time and at one of the places at which the instrument appointing the proxy, attorney or representative is required to be received under rule 13.10(f). 14.
