Regulation 20 Suspension of licences or certificates
Where any sum due by way of, or on account of, any fee or any part thereof payable under these Regulations remains unpaid by the holder of a licence or certificate, the licensing authority may serve a notice on him requiring payment of the sum unpaid and if, after a period of one month from the date of service of such notice, or such longer period as the licensing authority may allow, that sum remains unpaid, the licensing authority may forthwith suspend the licence or certificate until that sum has been paid.
