Meeting or exceeding registration limits

(1) The Commissioner may, by notice in writing given to a person, declare that reasonable grounds exist for believing that the value of a person’s supplies will meet or exceed the registration limits in section 23(l)(a)(ii) or 23(1 )(b), and for the purposes of section 23 the giving of that notice shall constitute reasonable grounds for so believing. (2) Where the Commissioner has given a notice to a person under sub-section (1) (referred to in this sub-section as “the former notice”) he may, by further notice in writing (referred to in this sub-section as “the revocation notice”) given to that person, revoke the former notice, and the declaration in the former notice shall accordingly cease to have effect from the date specified in the revocation notice.
