28(1)Subject to the provisions of this Part of this Act a borough council may at any time revoke a street trading licence if they are satisfied that—
(a)owing to circumstances which have arisen since the grant or renewal of the licence, there is not enough space in the street in which the licence holder trades for him to engage in the trading permitted by the licence without causing undue interference or inconvenience to persons or vehicular traffic using the street; or
(b)the licence holder is trading in a class of articles, things or services which the borough council have resolved under subsection (1) (b) of section 24 (Designation of licence streets) of this Act not to prescribe in licences granted for the licence street in which the licence holder trades; or
(c)the licence holder is an individual who has without reasonable excuse personally failed fully to avail himself of his licence; or
(d)the licence holder is on account of misconduct or for any other sufficient reason unsuitable to hold the licence; or
(e)that since the grant or renewal of the licence, the licence holder has for a period of four weeks or more failed to pay fees or charges due to the borough council in connection with the street trading licence or has failed to pay any charges due from him for accommodation provided in pursuance of subsection (2) of section 33 (Receptacles and containers) of this Act; or
(f)that since the grant or renewal of the licence, the licence holder has failed to make provision for the suitable and adequate storage of the receptacles used by him for trading or for any perishable goods in which he trades when trading is not taking place; or
(g)that since the grant or renewal of the licence, the licence holder has persistently failed to remove to a place of storage the receptacles used by him for trading; or
(h)that the licence holder has persistently failed to comply with any condition of his licence.
(2)If a borough council consider that a licence could be revoked on any of the grounds mentioned in paragraphs (a) to (c) of subsection (1) above they may instead of revoking it, vary its conditions by attaching further conditions—
(a)reducing the number of days in any week or the period in any one day during which the licence holder is permitted to trade; or
(b)specifying a different licence street or position or place in any such street at which the licence holder may sell or expose or offer for sale articles or things or offer or provide services; or
(c)restricting the description of articles, things or services in which the licence holder is permitted to trade.
