Here is the scenario: a local authority licences a hackney carriage or private hire driver. The authority becomes aware of that a serious allegation has been made against the driver: say a sexual assault upon a passenger. A criminal investigation is underway; the driver has been arrested, has exercised his right to silence (on legal advice), and has been released on police bail and is yet to be charged; the passenger’s identity is being kept secret. Can the local authority immediately suspend the driver’s licence pending investigations, with a full hearing to take place at a later date, when it can consider whether to revoke the licence?
Until the case of R. (on the application of Singh and others) v. Cardiff City Council  EHWC 1852 (Admin) it was thought that the answer was yes, it could.
