89. A person who is the appropriate person to make an endorsement or to originate an instruction may demand that the issuer not register a transfer of the security.
The demand is made by communicating a notice to the issuer setting out, among other things, the identity of the registered holder, the issue of which the security is a part, and the correspondence address of the person making the demand.
The issuer is under a duty to consider the demand only if the issuer has had a reasonable opportunity to act on it, having regard to the circumstances of receipt of the demand.
