Musgrove, R. v

Smart Summary

Anonymized Summary of Court of Appeal Opinion

Factual and Procedural Background

On 3 September 2024, in a trial at The City before Judge [Last Name], the Appellant (then aged 20) pleaded guilty to sixteen counts of blackmail. On 25 November 2024, at The City before Judge [Last Name], the Appellant (then aged 21) was sentenced to sixteen concurrent terms of 3 years and 4 months' custody to be served in a young offenders' institute. The sentencing judge also took into consideration 38 further offences (taken into consideration, "TICs"). The Appellant obtained leave to appeal the sentence from a single judge and now appeals against sentence.

The offending comprised a course of repeated blackmailing conduct from August 2023 to July 2024 affecting sixteen victims on the indictment and a further 38 materially similar offences taken into consideration (total 54 victims). The factual pattern was consistent across counts: in some cases the Appellant contacted acquaintances and convinced them to send money for gambling, then threatened harm or other consequences when further payments were refused; in other cases the Appellant messaged strangers on social media, invited them to gamble or falsely claimed they owed money for drugs and then threatened exposure, damage to property, or physical violence if demands were not met. Example threats included messages such as "I'm going to cut your legs off mate and feed them to my fish" and threats referencing victims' children or to damage their homes.

The Appellant was arrested on 5 November 2023 (six offences), bailed, then arrested again on 21 April 2024 (five further offences), bailed, and finally arrested on 5 August 2024 (a further five offences), the total of which correspond to the sixteen counts on the indictment. The 38 TICs covered the period December 2023 to July 2024: four occurred before the first arrest, fourteen between the first and second arrests, and twenty after the second arrest and before the final arrest. Financial losses on the indictment totaled £6,235; the TICs added £2,960; aggregate losses to all 54 victims were £9,195.

Two victim personal statements were before the court. Victim A described mental health effects, increased anxiety in social situations and shame. Victim B described being scared to leave home and worried about repaying borrowed money to satisfy the Appellant's demands.

Legal Issues Presented

  1. Whether the sentencing judge erred in law by failing to apply and engage with the sentencing guideline on offenders with mental disorders (including gambling disorder and ADHD) when assessing the Appellant's culpability and the impact of imprisonment.
  2. Whether any such error rendered the sentence manifestly excessive or wrong in principle.

Arguments of the Parties

Appellant's Arguments

  • The Appellant, through Attorney [Last Name], advanced a single ground of appeal: that the sentencing judge misdirected himself by treating the Appellant's gambling disorder as not amounting to an addiction and thereby failed to have proper regard to the guideline on sentencing offenders with mental disorders, developmental disorders, or neurological impairments.
  • It was submitted that the judge's approach meant he did not consider whether the Appellant's culpability should be reduced because of the gambling disorder or whether the impact of imprisonment should be increased; the result was a sentence that was manifestly excessive or wrong in principle.

The opinion does not contain a detailed account of any substantive responding argument from the prosecution.

Court's Reasoning and Analysis

The court considered the sentencing judge's findings and the material before him, including the pre-sentence report and the psychological assessment authored by Expert [Last Name]. The Expert's opinion was that the Appellant had a severe gambling disorder at the time of the offences, that gambling disorder significantly alters thinking, attention, decision making and behaviour, and that the disorder was the main cause of the index offences. The Expert further explained that gambling disorder sits alongside traditional addictions in diagnostic terms and described the relationship between gambling disorder and Attention Deficit Hyperactivity Disorder (ADHD), noting pathways such as impulsivity and high reward sensitivity.

The sentencing judge had acknowledged the Appellant's gambling disorder but expressed the view that gambling was "voluntary" and distinct from drug or alcohol addiction, concluding that the Appellant had planned the offences and had sufficient maturity and choice. The judge described a notional sentence after trial of seven years' imprisonment, reduced to five years to reflect mitigation, and then reduced by one-third for guilty pleas to reach the imposed concurrent terms of 40 months.

The Court of Appeal examined whether the sentencing judge had properly engaged with the guideline for offenders with mental disorders. The court noted the guideline's directions (including that expert evidence must be considered and that the sentencer should state clearly whether culpability was reduced and why) and found no compelling reasons to reject the Expert's opinion. The appellate court concluded the sentencing judge did not adequately apply the guideline: he failed to articulate whether the Appellant's culpability was reduced because of the gambling disorder and associated neurodiversity (including ADHD), and did not consider the possible increased impact of custody. The court therefore found an error in principle.

As remedial adjustment, the appellate court reduced the notional sentence that would have been imposed after trial by an additional six months (in addition to reductions the sentencing judge had applied for mitigation). The opinion sets out the arithmetic: starting from the identified notional seven-year (84 month) sentence after trial, the court described reductions leading to a notional 54 months before allowing the guilty-plea reduction, and then applying that reduction to reach an overall term of 36 months (3 years) concurrent on each count. The court did not identify any compelling reason to set aside the Expert's conclusions linking the gambling disorder and ADHD to the offending.

Holding and Implications

APPEAL ALLOWED

Holding: The Court of Appeal allowed the appeal, quashed the original sentences and imposed concurrent sentences of 3 years' detention in a young offenders' institute on each count.

Implications: The direct effect is that the Appellant's earlier concurrent sentences (40 months) were replaced by concurrent terms of 36 months (3 years) detention in a young offenders' institute. The court recorded that, because the Appellant was 18 at the date of conviction, the sentence should be recorded as detention in a young offenders' institute rather than as an adult sentence of imprisonment. The opinion identifies no new binding precedent; it addresses an error in principle in the application of existing sentencing guidance to an offender with a gambling disorder and associated neurodiversity.
