§ (2) Where the Commissioners are satisfied that on the day on which a registered person was registered he was not registrable, they may cancel his registration with effect from that day.
§ (3) The Commissioners shall not under sub-paragraph (1) above cancel a person's registration with effect from any time unless they are satisfied that it is not a time when that person would be subject to a requirement, or entitled, to be registered under this Act.
§ (4) In determining for the purposes of sub-paragraph (3) above whether a person would be subject to a requirement, or entitled, to be registered at any time, so much of any provision of this Act as prevents a person from becoming liable or entitled to be registered when he is already registered or when he is so liable under any other provision shall be disregarded.
