A concise, accessible Guide to the far reaching changes introduced by the Asylum & Immigration Act 2004. The Act, the third major piece of legislation in this area in five years, controversially excluded immigration decisions from the scrutiny of the higher courts in the original bill. Although the 'ouster' clause has been modified, the Act radically re-shapes the structure of immigration appeals as well as introducing important changes in practice and procedure. It is written by an experienced team of barristers from Doughty Street, a leading chambers at the forefront of human rights litigation. This Guide is a vital reference resource for practitioners and organisations working in this fast changing area of the Law.
