The fourth edition of Button on Taxis completely updates the text to take account of changes to legislation, case law and Guidance since the publication of the third edition. These include important Senior Court decisions relating to adoption of legislation, local authority decision-making processes, licence fees, Hackney carriage ranks, suitability of drivers and action against licensed vehicles. The legislative changes include extensions to the duration of certain licences and the ability for private hire operators to subcontract across local authority boundaries. In addition, the impact of booking systems such as Uber is considered together with the Law Commission's proposals for reform of Hackney carriage and private hire legislation. This new edition will provide a timely update to what is acknowledged as an essential handbook for the taxi licensing practitioner.
