21E+W+SParagraph 22 below shall apply to any decision of the local authority—
(a)to revoke a permanent licence under paragraph 8 above; or
(b)to vary under paragraph 8 any of the terms and conditions specified in a permanent licence under section 43(4)(b) and (c) of this Act in such manner that the holder of the licence will not be able to operate the licensed parking place to such advantage or potential advantage as if the variation had not been made; or
(c)to refuse an application by the holder of a permanent licence for a special variation of the terms and conditions specified under section 43(4)(b) and (c) in a case where—
(i)by reason of a happening beyond the control of the holder of the licence he cannot continue to operate the licensed parking place in accordance with the licence as for the time being in force to such advantage or potential advantage as before that happening; and
(ii)the making of that variation would wholly or partly mitigate the adverse effects of that happening without enabling the holder of the licence to operate the licensed parking place to greater advantage or potential advantage than before that happening.
