“21. Summarising the essential principles, the implementation of the United Kingdom’s Convention obligation is normally achieved by the proper exercise of the long established prosecutorial discretion which enables the Crown Prosecution Service, however strong the evidence may be, to decide that it would be inappropriate to proceed or to continue with the prosecution of a defendant who is unable to advance duress as a defence but who falls within the protective ambit of Article 26. This requires a judgment to be made by the CPS in the individual case in the light of all the available evidence. That responsibility is vested not in the court but in the prosecuting authority. The court may intervene in an individual case if its process is abused by using the ‘ultimate sanction’ of a stay of the proceedings. The burden of showing that the process is being or has been abused on the basis of the improper exercise of the prosecutorial discretion rests on the defendant. The limitations on this jurisdiction are clearly underlined in R v LM. The fact that it arises for consideration in the context of the proper implementation of the United Kingdom’s Convention obligation does not involve the creation of new principles. Rather, well established principles apply in the specific context of the Article 26 obligation, no more, and no less. Apart from the specific jurisdiction to stay proceedings where the process is abused, the court may also, if it thinks appropriate in the exercise of its sentencing responsibilities implement the Article 26 obligation in the language of the article itself, by dealing with the defendant in a way which does not constitute punishment, by ordering an absolute or a conditional discharge.”
“13. It is surely elementary that every court, whether a Crown Court or magistrates’ court, understands the abhorrence with which trafficking in human beings of any age is regarded both in the United Kingdom and throughout the civilised world. It has not, however, and could not have, been argued that if and when victims of trafficking participate or become involved in criminal activities, a trafficked individual should be given some kind of immunity from prosecution, just because he or she was or has been trafficked, nor for that reason alone, that a substantive defence to a criminal charge is available to a victim of trafficking. What, however, is clearly established, and numerous different papers, reports and decided cases have demonstrated, is that, when there is evidence that victims of trafficking have been involved in criminal activities, the investigation and the decision whether there should be a prosecution, and, if so, any subsequent proceedings, require to be approached with the greatest sensitivity. The reasoning is not always spelled out, and perhaps we should do so now. The criminality, or putting it another way, the culpability, of any victim of trafficking may be significantly diminished, and in some cases effectively extinguished, not merely because of age (always a relevant factor in the case of a child defendant) but because no realistic alternative was available to the exploited victim but to comply with the dominant force of another individual, or group of individuals.”
“There is no closed list of factors bearing on the prosecutor’s discretion to proceed against a VOT. Generalisation is best avoided. That said, factors obviously impacting on the discretion to prosecute go to the nexus between the crime committed by the defendant and the trafficking. If there is no reasonable nexus between the offence and the trafficking then, generally, there is no reason why (on trafficking grounds) the prosecution should not proceed. If there is a nexus, in some cases the levels of compulsion will be such that it will not be in the public interest for the prosecution to proceed. In other cases, it will be necessary to consider whether the compulsion was continuing and what, if any, reasonable alternatives were available to the VOT.”
“As always, the question for this court goes to the safety of the conviction. However, in the present context, that inquiry translates into a question of whether in the light of the law as it now is (this being a rare change in law case) and the facts now known as to the applicant (having regard to the admission of fresh evidence) the trial court should have stayed the proceedings as an abuse of process had an application been made. This question can be formulated indistinguishably in one of two ways which emerge from the authorities: was this a case where either: (1) the dominant force of compulsion, in the context of a very serious offence, was sufficient to reduce the applicant’s criminality or culpability to or below a point where it was not in the public interest for her to be prosecuted? or (2) the applicant would or might well not have been prosecuted in the public interest? If yes, then the proper course would be to quash the conviction …”
“The decision of the competent authority as to whether or not a person has been trafficked for the purpose of exploitation is not binding on the court, but, unless there is evidence to contradict it or significant evidence that has not been considered, it is likely that courts will respect the decision.”
