Hi Gondola,
Under the freedom of information act you will be able to request this information as it is absolutely in the public interest. The information released would be statistical rather than detailed, i.e. between 01/01/06 and 23/03/07 ** taxi drivers were licensed, despite having a conviction of a sexual nature.
The reason I belive that the information exists is that a local government officer would automatically refuse the initial licence application. It would then go to appeal, and the outcome would be decided by elected members. These meetings would be minuted.
Can a Councillor please confirm if this is an accurate assumption?
