Harm Categorisation in Robbery and Re-evaluation of Dangerousness for Extended Sentences in Youthful Offenders

1. Introduction

In Agwo, R. v [2026] EWCA Crim 614, the Court of Appeal (Criminal Division) reviewed a sentence imposed by the Crown Court at Birmingham following guilty pleas to multiple robberies and attempted robberies committed over several weeks in Birmingham city centre. The offending involved targeting lone, young victims, intimidation, and repeated threats to stab; in at least one incident a knife was produced.

The sentencing judge imposed an extended determinate sentence under section 266 of the Sentencing Act 2020 on the lead robbery count, alongside concurrent terms for the remaining counts. The appellant challenged (i) the guideline categorisation of harm for the lead offence, (ii) the finding of dangerousness and the procedure adopted when imposing an extended sentence, and (iii) overall excessiveness.

2. Summary of the Judgment

The Court of Appeal allowed the appeal in part. It held that the lead offence had been mis-categorised for harm under the robbery guideline: there was insufficient material before the sentencing judge to place the harm in the category requiring evidence of severe psychological harm. The correct categorisation was harm category 2 with culpability A due to the knife threat/production.

However, the Court of Appeal independently re-evaluated dangerousness (given the brevity of the sentencing remarks and the judge not having tried the case) and concluded the appellant was dangerous for the purposes of the 2020 Act and that a determinate sentence alone would be insufficient to protect the public.

The Court quashed the original extended sentence and substituted an extended sentence of 7 years comprising: 4 years’ custody and an extended licence period of 3 years (reduced from 4). The remaining concurrent sentences were left undisturbed.

3. Analysis

3.1 Precedents Cited

(a) R v Parry [2016] EWCA Crim 1822

The appellant relied on R v Parry [2016] EWCA Crim 1822 for the proposition that, where the court is contemplating an extended sentence/dangerousness finding, it will generally be appropriate to invite submissions on that issue. The Court of Appeal in the present case noted the point but did not determine the appeal on procedural unfairness alone. Instead, it addressed the substance by conducting its own re-evaluation of dangerousness.

Practical significance: the decision reinforces that, even where the appellate court can cure deficiencies by re-assessment, failure to invite submissions remains a recognised procedural risk—especially where the sentencing outcome is unusually onerous and dependent on evaluative judgments about risk.

(b) R v Leighton Williams [2024] EWCA Crim 686

The Court cited R v Leighton Williams [2024] EWCA Crim 686 for the restraint principle: appellate interference with dangerousness/extended sentence decisions is generally limited to cases of error of principle or outcomes outside the reasonable range on the material before the court.

The present case illustrates an important qualification: where the sentencing judge did not try the case and provides exiguous reasons (particularly with an 18-year-old and substantial personal mitigation), the appellate court may find it necessary to undertake a more searching re-evaluation rather than defer.

3.2 Legal Reasoning

(a) Robbery guideline: harm categorisation must be evidenced

The sentencing judge adopted the prosecution’s assessment that the lead robbery was category 1A (knife used to threaten violence and serious psychological harm said to have resulted). The Court of Appeal held this was incorrect on the information available at sentence: the judge was not the trial judge and there was no evidence before him sufficient to justify a finding of severe psychological harm. There were also no physical injuries.

The Court accordingly placed the case in harm category 2, while maintaining culpability A because the knife threat/production was made out. It identified the adult guideline starting point for category 2A as 5 years (range 4–8).

This is a clear appellate warning against “up-categorisation” of harm based on inference, assertion, or generalised assumptions about trauma. Where severe psychological harm is relied upon to reach the most serious category, there must be an evidential basis (for example, material in victim statements, medical or other evidence, or detailed factual findings properly supported by the record).

(b) Youthful offenders: 18 is not a maturity cliff-edge

The Court stressed a well-established sentencing insight: there is no sudden change in maturity at 18. It also considered that the appellant’s developmental age appeared lower than his chronological age, with a background of bereavement, instability, and disrupted support.

This fed into mitigation and the calibration of the headline term. The Court balanced mitigation against substantial aggravating features: a sustained pattern of similar offences; repeated targeting of young victims; threats involving a dangerous weapon; prior convictions; and the fact that concurrent sentences were required for multiple additional offences.

(c) Recasting the headline term and applying plea credit

The Court’s approach was structured:

  • It assessed that for an adult offender, the lead offence after trial and before mitigation would be about 8 years (reflecting the seriousness of category 2A robbery in context, plus the pattern of offending and aggravation).
  • After considering youth/immaturity and personal mitigation, it reduced the overall sentence for the lead offence to 6 years.
  • Applying guilty plea credit, it arrived at an appropriate custodial period of 4 years.

Importantly, the Court noted that with a 4-year custodial term the statutory threshold condition for section 266 was satisfied (a crucial step when deciding whether an extended determinate sentence is legally available).

(d) Dangerousness and section 266: why the Court upheld the finding

Despite correcting the guideline categorisation and reducing the custodial element, the Court upheld dangerousness after conducting its own assessment. It identified a significant risk of serious harm from further specified offences, relying on:

  • The nature of the offences: knife threats against lone young persons, sometimes in locations difficult to escape.
  • The pattern and repetition across several weeks.
  • Indications that offending was not solely acquisitive but also for “thrill”/enjoyment.
  • The pre-sentence report’s high-risk assessment and the history of unsuccessful interventions.

The Court then addressed the second-stage protective assessment: whether an ordinary determinate sentence would be sufficient to protect the public. It concluded it would not, justifying the imposition of an extended sentence notwithstanding the offender’s youth.

(e) Extended licence: necessity and sufficiency

The Court reduced the extended licence period from 4 years to 3 years, applying a necessity-based approach: the period must be necessary and sufficient for public protection. This reflects the statutory logic of section 266: the extension is not punitive in itself, but protective, and should be tailored to the demonstrated risk.

3.3 Impact

  • Evidence-driven harm categorisation: Sentencers should avoid placing robbery into the highest harm category without a sound evidential basis, particularly where “severe psychological harm” is the differentiator and the judge has not heard a trial.
  • Reasoned dangerousness findings are critical: Where a court imposes an extended sentence—especially on a young adult—it should give clear reasons addressing (i) why there is a significant risk of serious harm and (ii) why a determinate sentence is insufficient for public protection. Sparse reasoning increases the likelihood of appellate re-evaluation.
  • 18-year-olds and maturity: The judgment reinforces that youth and developmental immaturity can materially affect sentence length even in serious robberies, though they do not preclude dangerousness where the facts and risk assessment support it.
  • Calibration of extended licence: The reduction of the extended licence term highlights that extension length must be justified by protection needs, not applied by default at the upper end.

4. Complex Concepts Simplified

  • Robbery guideline categorisation (harm/culpability): The Sentencing Council guideline uses two axes. “Culpability” measures how the robbery was committed (e.g., weapon threats). “Harm” measures the impact and seriousness (including injuries or severe psychological effects). The category selected drives the starting point and range.
  • Extended Determinate Sentence (EDS) (Sentencing Act 2020, s266): A sentence with (i) a custodial term and (ii) an extended licence period after release. It is used where an offender is “dangerous” and extra supervision is needed to protect the public.
  • Dangerousness: A legal conclusion that there is a significant risk of the offender causing serious harm to the public through further specified offences. It is not based on the offence alone; courts consider patterns, background, prior convictions, and risk assessments.
  • Extended licence period: Extra time on licence after release, during which the offender can be recalled to custody if risk escalates or conditions are breached. It must be proportionate to public protection needs.
  • “Exiguous” sentencing remarks: Very brief reasons. In serious cases, especially involving dangerousness and youth, inadequate reasoning may trigger closer appellate scrutiny.

5. Conclusion

Agwo, R. v [2026] EWCA Crim 614 provides a clear reminder that robbery guideline harm categories—particularly those hinging on severe psychological harm—must be supported by adequate material, and that miscategorisation can materially inflate the sentencing starting point. At the same time, the case confirms that where the facts disclose repeated knife threats, a pattern of predatory street offending, and a supported high-risk assessment, the Court may uphold a dangerousness finding and the need for an extended sentence, while still tailoring both custody and the length of extended licence to what is necessary and sufficient for public protection.
