"A decision of the judge under this Part may be questioned in legal proceedings only by means of an appeal under this Part."
"... it is a fundamental point of principle that any use of the procedures that exist for depriving a person of his liberty must be carefully scrutinised. Lord Atkin's declaration in Liversidge v Anderson[1942] AC 206 , 245: 'that in English law every imprisonment is prima facie unlawful and that it is for a person directing imprisonment to justify his act' has lost none of the force which it had when it was delivered over sixty years ago. When, In re Farinha (Antonio da Costa) [1992] Imm AR 174, 178 Mann LJ said that the courts must be vigilant to ensure that the extradition procedures are strictly observed, he was making precisely the same point. The importance of this principle cannot be over-emphasised."
