"In relation to [C4], the features I have already mentioned require me to move upwards from the starting point. Even when I take into account all the things in your favour, the sentence remains above the starting point. The reduction I apply to allow for your age is much less than for the other offences. The sentence I would have imposed for this offence is 5 years but I increase this to 8 years to take into account all the other offences."
"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."
