"6.1 There will be occasions when an increase in the age of a child or young person will result in the maximum sentence on the date of the finding of guilt being greater than that available on the date on which the offence was committed (primarily turning 12, 15 or 18 years old). 6.2. In such situations the court should take as its starting point the sentence likely to have been imposed on the date at which the offence was committed. This includes young people who attain the age of 18 between the commission and the finding of guilt of the offence26 but when this occurs the purpose of sentencing adult offenders27 has to be taken into account, which is: • the punishment of offenders; • the reduction of crime (including its reduction by deterrence); • the reform and rehabilitation of offenders; • the protection of the public; and • the making of reparation by offenders to persons affected by their offences. 6.3 When any significant age threshold is passed it will rarely be appropriate that a more severe sentence than the maximum that the court could have imposed at the time the offence was committed should be imposed. However, a sentence at or close to that maximum may be appropriate."
