Article 15

In a case where the holder of a public service vehicle licence, whether on being granted a PSV operator's licence or otherwise, surrenders a public service vehicle licence there shall be refunded to him such a sum as represents the proportion of the fee attributable to the number of complete months to which that licence relates and which at the date of the surrender have not expired, and in a case where the said holder is granted a PSV operator's licence the traffic commissioners may make the said refund by off-setting the amount thereof against the fee due in respect of the PSV operator's licence.

No refund of any part of a fee paid for a public service vehicle licence shall be due in respect of any period during which the licence is, by virtue of Article 13, used as an operator's disc.
