If the Commission is of the opinion that –

(a) a perpetual taxi licence is inactive; and

(b) the result of the licence being inactive is a restriction of competition in the taxi area to which the licence relates –

the Commission may, by notice in writing given to the owner of the licence, require the owner of the licence to provide to the Commission no later than the date specified in the notice such evidence as the Commission may require in order to be satisfied that a taxi service is being operated under the authority of that licence.
