R v Bayleigh Darren Howden

When deciding whether to suspend a custodial sentence for an offender with a mental, developmental or neurological impairment, the sentencer must assess culpability under the relevant offence-specific guideline and consider whether the impairment is sufficiently connected with the offending. The court must also weigh whether custody is proportionate, the rehabilitative approach, and the impact of the impairment on sentence length and suspension. Seriousness remains important, but it must not overwhelm significant mitigation supported by expert evidence, personal circumstances and good character. A refusal to suspend is wrong where it gives insufficient weight to those matters and to the relevant sentencing guideline.

The appellant pleaded guilty in the Crown Court at Southampton to inflicting grievous bodily harm, contrary to section 20 of the Offences Against the Person Act 1861. He received 18 months’ imprisonment. The custodial term itself was not challenged, but the sentencing judge refused to suspend it, principally because of the seriousness of the offence.

The appellant relied on his previous good character, remorse, rehabilitation prospects and a clinical psychologist’s evidence that Autism and Attention Deficit Disorder had significantly influenced his decision-making and behaviour. The appeal concerned whether the refusal to suspend the sentence gave sufficient weight to that evidence and to the relevant sentencing guidance.

1. Culpability and neurodiversity. The Sentencing Offenders with Mental Disorders, Developmental Disorders or Neurological Impairments Guideline required the sentencer first to assess culpability under the relevant offence-specific guideline, then to consider whether culpability was reduced by the impairment or disorder. Reduction depended on a sufficient connection between the impairment and the offending, requiring careful analysis of the circumstances and relevant material. The appellant’s expert evidence established a significant connection between his Autism and ADD and the decision-making and behaviour involved in the offence.
2. Custody and suspension. The Guideline also required consideration, particularly where custody was at issue, of whether the impairment made custody disproportionate to the aims of sentencing and whether public protection and crime reduction would be better served by rehabilitation. Where custody was unavoidable, the impact of the impairment could bear on both sentence length and whether the sentence should be suspended.
3. Application. The judge was entitled to regard the appellant’s following of an elderly and vulnerable complainant to his home and the subsequent assault as aggravating matters. However, the seriousness of the offence was given excessive weight. The report, the circumstances of the offence, the appellant’s previous good character and the significant mitigation should have led to suspension of the 18-month term. The judge had therefore failed to give sufficient weight to the mitigation and the Guideline.
4. Disposition. In the exceptional circumstances, the appeal was allowed. The sentence of 18 months’ imprisonment was quashed and replaced by 18 months’ imprisonment suspended for 24 months, with a 20-day Rehabilitation Activity Requirement addressing emotional management, consequential thinking, alcohol misuse and liaison with mental health services, together with 100 hours of unpaid work.

1. Court of Appeal (Criminal Division): The appeal against sentence was allowed. The 18-month custodial sentence was quashed and replaced with an 18-month sentence suspended for 24 months: [2026] EWCA Crim 366.
2. Crown Court at Southampton: On 9 January 2026, the appellant was sentenced to 18 months’ imprisonment following his guilty plea.
