R v Harry Benson

On a reference against an allegedly unduly lenient sentence, the threshold is more than mere leniency. The sentence must materially fail to reflect the offender’s overall criminality. Sentencing must properly account for harm, culpability, significant aggravating features and concurrent offences. Where evidence shows that neurodiversity played no part in the offending and the offender has adapted to custody, it may not justify a substantial reduction based on the supposed additional hardship of imprisonment.

The Solicitor General sought leave to refer a sentence imposed by the Crown Court at Aylesbury on 13 June 2025. The defendant had received four years and three months’ imprisonment for causing grievous bodily harm with intent, together with concurrent sentences for possessing bladed articles and an offensive weapon, and possession of cannabis. The central issues were the correct harm category, the effect of multiple culpability and aggravating factors, the treatment of concurrent weapons offences, and the weight to be given to personal mitigation, including alleged neurodiversity and progress in custody.

The Court granted leave and held that the sentence was unduly lenient.

1. The submission that the principal motivation was obtaining money, rather than revenge, was rejected. The defendant had taken a knife to the victim’s home and had used it after the attempted extortion failed. That demonstrated significant planning connected with revenge.
2. The offence belonged in category A2 of the relevant sentencing guideline. The court relied on the serious and continuing physical injuries and the profound psychological effect on the victim and his partner. The sentence then required significant upward movement because of three culpability factors: premeditation and planning, use of a highly dangerous weapon, and revenge.
3. Further aggravating features included the threats to the victim’s dogs and family, the unprovoked attack and commission of the offence while under the influence of cocaine. An additional upward adjustment was required to reflect the concurrent offences involving the ice pick, lock knife and extendable baton.
4. The mitigation was limited. Testimonials could provide only a small degree of mitigation in the circumstances. The psychiatric evidence supported the conclusion that neurodiversity had not contributed to the offending. It did not justify treating imprisonment as more challenging than for most prisoners, particularly given the defendant’s ability to adapt to custody and his satisfactory experience on remand.
5. The appropriate sentence after trial was not less than about seven and a half years. Applying the accepted 15 per cent credit for pleas produced a sentence of six years and three months. The sentence on count 6 was substituted accordingly, while the other concurrent sentences remained undisturbed.

• Court of Appeal (Criminal Division): On 11 November 2025, granted leave to refer the sentence as unduly lenient and substituted six years and three months’ imprisonment on count 6: [2025] EWCA Crim 1860.
• Crown Court at Aylesbury: On 13 June 2025, imposed an overall sentence of four years and three months’ imprisonment, with concurrent sentences for the additional offences.
