"The Sentencing Council has published a Definitive Guideline which sets out Overarching Principles for Sentencing Children and Young People. Because the sentence for murder is fixed by law, the nature of the sentence is not affected by considerations of the welfare of the offender, or of the principal aim of the youth justice system which is to reduce offending by children and young persons. It nonetheless remains important when considering the appropriate minimum term to consider the developmental and emotional age of the offender and to consider, in accordance with paragraph 4.10 of the guideline, whether the young offender has: 'the necessary maturity to appreciate fully the consequences of their conduct, the extent to which the child or young person has been acting on an impulsive basis and whether their conduct has been affected by inexperience, emotional volatility or negative influences.'"
