“There must have been an unlawful act from [S] given the ferocity of the argument and the presence of the knife. It must have been intentionally performed, and a reasonable person would realise the inevitable risk of some harm coming to Jourdain.”
“It is accepted by everyone that there was an argument between the two for some time with loud shouting by both and at times crying from Jourdain. However, that is not enough in itself to infer a threat of violence. People do shout at each other when arguing, and clearly emotions were running high but … there is insufficient evidence to prove any unlawful act amounting to threats of use of violence on the part of this suspect which directly caused her to jump off the balcony to escape, or which caused her to fall accidentally while trying to escape an unlawful act. Again I should emphasise that the entire case against the suspect would rest on the prosecution proving that such an unlawful act took place. I am sorry but despite all the efforts of the investigating officers … no such evidence is available. I accept it is possible that Jourdain went onto the balcony during the argument, to get away from the suspect because he had just assaulted her or threatened her with immediate violence. However, it is equally plausible that she went out there in a state of high emotion, misjudged the situation and slipped/fell and screamed for help as she realised she was going to fall. That is, of course, speculation, but in my view no more so than the theory that the suspect threatened or assaulted her to the extent that she tried to escape and in doing so, jumped or fell off the balcony. The point is that there is not sufficient evidence to support or undermine any of the possibilities as to how she came to fall to the ground.”
“The primary decision to prosecute or not to prosecute is entrusted by Parliament to the Director as head of an independent, professional prosecuting service, answerable to the Attorney General in his role as guardian of the public interest, and to no one else. It makes no difference that the decision will ordinarily be taken by a senior member of the Crown Prosecution Service, as it was here, and not by the Director personally. In any borderline case the decision may be one of acute difficulty, since while a defendant whom the jury would be likely to convict should properly be brought to justice and tried, a defendant whom a jury would be likely to acquit should not be subjected to the trauma inherent in a criminal trial. … The Director and his officials (and senior Treasury Counsel when consulted) will bring to their task of deciding whether to prosecute an experience and expertise which most courts called upon to review their decision could not match. In most cases the decision will turn not on an analysis of the relevant legal principles but on the exercise of an informed judgment of how a case against a particular defendant, if brought, would be likely to fare in the context of a criminal trial before (in a serious case such as this) a jury. This exercise of judgment involves an assessment of the strength, by the end of the trial, of the evidence against the defendant and the likely defences. It will often be impossible to stigmatise a judgment on such matters as wrong even if one disagrees with it. So the courts will not easily find that a decision not to prosecute is bad in law, on which basis alone the court is entitled to interfere. At the same time the standard of review should not be set too high, since judicial review is the only means by which the citizen can seek redress against a decision not to prosecute and if the test were too exacting an effective remedy would be denied.”
