"21. We have reflected on those submissions. In our judgment, the applicable principles are clear. Those who are under the age of 18 when they offend have long been treated by Parliament, and by the courts, differently from those who are adults. That is because of a recognition that, in general, children are less culpable, and less morally responsible for their acts than adults. They require a different approach to sentencing and are not to be treated as if they were just cut-down versions of adult offenders. The statutory provisions in force from time to time have frequently restricted the availability of custodial sentences for child offenders, whether by prohibiting them altogether for those below a certain age or, more commonly, by restricting on a basis of age the type and maximum length of custody in all but grave cases. All such provisions are in themselves a recognition by Parliament of the differing levels of culpability as between a child and an adult offender: that is one of the reasons why we are respectfully unable to agree with the distinction drawn in Forbes between cases where no custody would have been available, and cases where some form of custody (however far removed from modern sentencing powers) would have been available. There is, in our view, no reason why the distinction in levels of culpability should be lost merely because there has been an elapse of time which means that the offender is an adult when sentenced for offences committed as a child. 22. Section 59(1) of the Sentencing Code requires every court, when sentencing or dealing with an offender who was under the age of 18 at the time of the offending, to follow the Children guideline except in the rare case when the court considers it would be contrary to the interests of justice to do so. Paragraphs 6.1 to 6.3 of that guideline are relevant in such circumstances, and we are unable to see any justification in logic or principle for the submission that those paragraphs should only be followed where the offender has only recently attained adulthood. They remain relevant, and therefore to be followed, however many years have elapsed between the offending and the sentencing. That is because the passage of time does not alter the fact of the offender's young age at the time of the offending. It does not increase the culpability which he bore at that time. We naturally hesitate to differ from the decisions in H(J) and Forbes; But insofar as those cases adopted a different approach, it is our respectful view that the court did not have regard to the passages in the SGC Youth guideline which were to substantially the same effect as paragraphs 6.1 to 6.3 in the current Children guideline. In our view, the application of the Children guideline requires sentencers to adopt a different approach between sentencing for historical offending committed as a child and sentencing for historical offending committed as an adult. That difference, and the resultant difference (which may be substantial) in the respective sentences, is in accordance with principle and reflects the special approach to the sentencing of child offenders."
"Any penetrative activity involving coercion, exploitation or pressure Use or threats of violence against the victim or someone known to the victim Prolonged detention/sustained incident Severe psychological or physical harm caused to the victim."
"Where a custodial sentence is unavoidable the length of custody imposed must be the shortest commensurate with the seriousness of the offence. The court may want to consider the equivalent adult guideline in order to determine the appropriate length of the sentence. If considering the adult guideline, the court may feel it appropriate to apply a sentence broadly within the region of half to two thirds of the appropriate adult sentence for those aged 15 – 17 and allow a greater reduction for those aged under 15. This is only a rough guide and must not be applied mechanistically. The individual factors relating to the offence and the child or young person are of the greatest importance and may present good reason to impose a sentence outside of this range."
