IGG, R. v [2026] EWCA Crim 419 (12 March 2026)

The sentencing judge was entitled to conclude that the appellant's neurodiversity, age, and immaturity did not reduce her culpability for the offence, and that the aggravating features justified a sentence at the top of the guideline range. The judge properly considered all relevant mitigating and aggravating factors, and the sentence of 15 years' imprisonment was not manifestly excessive.
