“First, that the decision whether to prosecute or not must always be made by the Crown Prosecution Service and not the court. The court does not make prosecutorial decisions. Second, provided there is evidence from which the jury may properly convict, it can only be in the rarest circumstances that the prosecution may be required to justify the decision to prosecute.”
“In relation to the jurisdiction of the Crown Court, other than its jurisdiction in matters relating to trial on indictment, the High Court shall have all such jurisdiction to make mandatory, prohibiting or quashing orders as the High Court possesses in relation to the jurisdiction of an inferior court.”
“It is in any event clear, I apprehend, that certain orders made at the conclusion of a trial on indictment are excluded from judicial review as “relating to trial on indictment” not because they affect the conduct of the trial, but rather because they are themselves an integral part of the trial process. This is obviously true of the verdict and sentence. It is equally true, according to the provisional view I expressed in In re Smalley, of certain orders for the payment of costs made under the Costs inCriminal Cases Act 1973 .”
“An order that a convicted defendant pay the whole or any part of the costs of the prosecution under section 4(1)(a) is appealable under theCriminal Appeal Act 1968 as part of the sentence: Reg. v. Hayden [1975] 1 W.L.R. 852. An order that the prosecutor pay the whole or any part of the costs of an acquitted defendant under section 4(1)(b) is not appealable, nor is any decision under section 3(1) either to make or to refrain from making an order for payment of costs out of central funds in favour of the prosecution or the defence. The common characteristic of all decisions made by the Crown Court under these provisions is that the court is exercising a discretion in the light of what it has learned in the course of the trial as to the nature of the case, both for the prosecution and the defence, and in the light of the conduct and the outcome of the trial itself: see the guidance given by the Practice Direction (Costs: Acquittal of Defendant) [1981] 1 W.L.R. 1383. It follows that all such decisions are so intimately bound up with the trial process that they must be treated as an integral part of it and thus must be considered as made in the exercise of the Crown Court's Jurisdiction “relating to trial on indictment” and accordingly are not subject to judicial review.”
“We therefore hope that this judgment may give guidance which will be of value to criminal courts as to civil, but we fully appreciate that the conduct of criminal cases will often raise different questions and depend on different circumstances.”
