Black cab drivers had argued that by using GPS signals to calculate the cost of a journey, Uber was breaching a law which bans private hire cars from being equipped with taximeters. Transport for London (TfL) went to court for clarification, where Mr Justice Ouseley handed Uber a decisive victory. He said the app operates differently to a taximeter. The Licensed Taxi Drivers Association said: "The law really is an ass." An appeal is planned.
