"a man is not to be deprived of his liberty except in due course and process of law." and "... if a man is to be deprived of his freedom, he is entitled to know the reason why."
"There may well be other exceptions to the general rule in addition to those I have indicated, and the above propositions are not intended to constitute a formal or complete code, but to indicate the general principles of our law on a very important matter."
"In all such matters a wide measure of discretion must be left to those whose duty it is to preserve the peace and bring criminals to justice."
"having regard to all the circumstances, including the circumstances in which the evidence was obtained, ... would have such an adverse effect on the fairness of the proceedings that the court ought not to admit it."
"Your Lordships' House in R v. Sang and the many decisions which have followed it make it plain that as a matter of English law evidence which is obtained improperly or even unlawfully remains admissible, subject to the power of the trial judge to exclude it in the exercise of his common law discretion or under ... Section 78...."
"... if the behaviour of the police in the particular case amounts to an apparent or probable breach of some relevant law or convention, common sense dictates that this is a consideration which may be taken into account for what it is worth. Its significance, however, will normally be determined not so much by its apparent unlawfulness or irregularity as upon its effect, taken as a whole, upon the fairness or unfairness of the proceedings."
"... the discretionary powers of the trial judge to exclude evidence march hand in hand with article 6.1 of the European Convention of Human Rights. Both are concerned to ensure that those facing criminal charges receive a fair hearing. Accordingly, when considering the common law and statutory discretionary powers under English law the jurisprudence on article 6 can have a valuable role to play. English law relating to the ingredients of a fair trial is highly developed. But every system of law stands to benefit by an awareness of the answers given by other courts and tribunals to similar problems. In the present case the decision of the European Court of Human Rights in Schenk v. Switzerland(1988) 13 EHRR 242 confirms that the use at a criminal trial of material obtained in breach of the rights of privacy enshrined in article 8 does not of itself mean that the trial is unfair. Thus the ECHR case law on this issue leads to the same conclusion as the English law."
"In my view this was persistent, careful and detailed planning. It involved the proposed carrying of firearms and the determination and the attitudes to those who might be involved as victims, mentioned on the tapes, make at times chilling reading. The targets discussed were a supermarket and a postal van or possibly a sorting office. It is plain there was a detailed reconnaissance. On17 March 1994 I am satisfied that you actually set out with others to commit an armed robbery, but it did not in law or in fact go so far as an attempt, but it was, as you yourself described it on 31 August, a brilliant plan which could have worked if too many people had not known of it and caused it to go wrong."
"This activity, the planning, the talk was spread over a period of about six months. Having read the conversations carefully and considered the rest of the evidence and what was said, I am satisfied that if you had not been arrested on20 September 1994 , the matter discovered and the kit taken there would, sooner rather than later, have been an attack on one or more of the proposed targets."
