This thesis provides a study on the role of judicial review in safe third country cases. A 'safe third country case' may be defined as a legal challenge by an asylum seeker against removal from the United Kingdom to a third state in the absence of substantive determination of an application for asylum. A 'safe third country' is defined as a state where an asylum seeker has found some form of protection and from which has moved on, a territory travelled through en route where it is deemed that protection could have been sought, a state where asylum has been requested and previously refused, or any other territory that an asylum seeker may be removed to on the basis of prior connection.
