Paragraph 65

The instrument appointing a proxy shall be in writing under the hand of the appointor or of his attorney duly authorised in writing, or, if the appointor is a corporation, either under the common seal, or under the hand of an officer or attorney so authorised. No person shall act as a proxy unless either he is entitled on his own behalf to be present and vote at the meeting at which he acts as proxy, or he has been appointed to act at that meeting as proxy for a corporation.
