The Secretary of State may revoke or vary a prohibition notice by serving on the trader a notification stating that the notice is revoked or, as the case may be, is varied as specified in the notification.

The Secretary of State shall not vary a prohibition notice so as to make the effect of the notice more restrictive for the trader.

Without prejudice to the power conferred by section 13(2) of this Act, the service of a notification under sub-paragraph (1) above shall be sufficient to satisfy the requirement of paragraph 4(2) above that the trader shall be informed of the Secretary of State’s decision.
