A member of the committee may, in relation to the business of the committee, be represented by another person duly authorised by him for that purpose.

A person acting as a committee-member's representative must hold a letter of authority entitling him so to act (either generally or specially) and signed by or on behalf of the committee-member.

The chairman at any meeting of the committee may call on a person claiming to act as a committee-member's representative to produce his letter of authority, and may exclude him if it appears that his authority is deficient.

No member may be represented by a body corporate, or by a person who is an undischarged bankrupt, or is subject to a composition or arrangement with his creditors.

Where a member's representative signs any document on the member's behalf, the fact that he so signs must be stated below his signature.
