(2)A permit under this paragraph shall be granted by the Commissioners within fourteen days of the date when application is made for it, and shall continue in force unless and until revoked under paragraph 12(3) below, except that—
(a)the Commissioners may refuse to grant such a permit to any person or in respect of any premises or totalisator if within the twelve months immediately preceding the application a previous permit under this paragraph granted to that person or in respect of those premises or that totalisator has been revoked under the said paragraph 12(3); and
(b)the Commissioners may at any time revoke such a permit by notice in writing to the holder if it appears to them that the holder is not carrying on a business for which such a permit is required or is not using the premises or totalisator in respect of which the permit was granted for the purposes of such a business.
