“[19] We are not at present concerned with the second of these categories (which we will call ‘Category 2’ cases), in which a court is not prepared to allow a prosecution to proceed because it is not being pursued in good faith, or because the prosecutors have been guilty of such serious misbehaviour that they should not be allowed to benefit from it to the defendant’s detriment. In some of those cases it is this court, rather than any lower court, which possesses the requisite jurisdiction (see ex p Watts, per Buxton LJ at p 195B-D). [20] In these cases the question is not so much whether the defendant can be fairly tried, but rather whether for some reason connected with the prosecutors’ conduct it would be unfair to him if the court were to permit them to proceed at all. The court’s enquiry is directed more to the prosecutors’ behaviour than to the fairness of the eventual trial. Although it may well be possible for the defendant to have a fair trial eventually, the court may be satisfied that it is not fair that he should be put to the trouble and inconvenience of being tried at all.”
“Subject to the provisions of these rules, a tribunal may regulate its own procedure”
“… this is a case about abuse of the process of the High Court. It concerns the inherent power which any court of justice must possess to prevent misuse of its procedure in a way which, although not inconsistent with the literal application of its procedural rules, would nevertheless be manifestly unfair to a party to litigation before it, or would otherwise bring the administration of justice into disrepute among right-thinking people. The circumstances in which abuse of process can arise are very varied; those which give rise to the instant appeal must surely be unique. It would, in my view, be most unwise if this House were to use this occasion to say anything that might be taken as limiting to fixed categories the kinds of circumstances in which the court has a duty (I disavow the word discretion) to exercise this salutary power.”
“Subject to the provisions of the [Tribunals, Courts and Enforcement Act 2007 ] and any other enactment, the Tribunal may regulate its own procedure.”
“(1) The proceedings, or the appropriate part of them, will automatically be struck out if the appellant has failed to comply with a direction that stated that failure by a party to comply with the direction would lead to the striking out of the proceedings or that part of them. (2) The Tribunal must strike out the whole or a part of the proceedings if the Tribunal— (a) does not have jurisdiction in relation to the proceedings or that part of them; and (b) does not exercise its power under rule 5(3)(k)(i) (transfer to another court or tribunal) in relation to the proceedings or that part of them. (3) The Tribunal may strike out the whole or a part of the proceedings if— (a) the appellant has failed to comply with a direction which stated that failure by the appellant to comply with the direction could lead to the striking out of the proceedings or part of them; (b) the appellant has failed to co-operate with the Tribunal to such an extent that the Tribunal cannot deal with the proceedings fairly and justly; or (c) the Tribunal considers there is no reasonable prospect of the appellant’s case, or part of it, succeeding. (4) The Tribunal may not strike out the whole or a part of the proceedings under paragraphs (2) or (3)(b) or (c) without first giving the appellant an opportunity to make representations in relation to the proposed striking out. (5) If the proceedings, or part of them, have been struck out under paragraphs (1) or (3)(a), the appellant may apply for the proceedings, or part of them, to be reinstated. (6) An application under paragraph (5) must be made in writing and received by the Tribunal within 28 days after the date that the Tribunal sent notification of the striking out to the appellant. (7) This rule applies to a respondent as it applies to an appellant except that— (a) a reference to the striking out of the proceedings must be read as a reference to the barring of the respondent from taking further part in the proceedings; and (b) a reference to an application for the reinstatement of proceedings which have been struck out must be read as a reference to an application for the lifting of the bar on the respondent taking further part in the proceedings. (8) If a respondent has been barred from taking further part in proceedings under this rule and that bar has not been lifted, the Tribunal need not consider any response or other submissions made by that respondent, and may summarily determine any or all issues against that respondent.”
“Within the general jurisdiction … there is a limited category of cases, involving infractions of the rule of law outside the narrow confines of the actual trial or court process, where the magistrates do not have jurisdiction, or alternatively as a matter of law should not exercise such jurisdiction as they may have. So much is clear from Lord Griffiths's speech in Bennett, though the exact reach of this category remains to be determined. Such cases should, as in Bennett, be addressed by the wider supervisory jurisdiction of the Divisional Court. That category is however a narrow one. It excludes every complaint that is directed at the fairness or propriety of the trial process itself.”
