Age at Sentence Cannot Uplift a Youth-Discounted Robbery Sentence; Avoid Double Counting Business Harm

1) Introduction

In R v Oluwasina [2026] EWCA Crim 594, the Court of Appeal (Criminal Division) (Holgate LJ, Garnham J, and HHJ Timothy Spencer KC sitting) revisited the correct methodology for sentencing a robbery committed by a child but sentenced as an adult. The appellant pleaded guilty to robbery (committed at age 17) and was later sentenced (at age 20) to 46 months’ detention in a young offender institution by the Crown Court at Wolverhampton (HHJ Barry Berlin).

The offence involved a planned street-and-shop style robbery at a convenience store: the appellant entered wearing a balaclava and gloves, grabbed the shop assistant, produced a large knife, took her mobile phone (with her bank card) and cigarettes, and later used the card to buy a gift card. A knife, gloves and balaclava were later found at his home.

The appeal raised two core issues: (i) the proper guideline starting point and (ii) whether, having reduced sentence to reflect the appellant’s youth at the time of the offence, the Crown Court could then increase the sentence because he was an adult at the date of sentence.

2) Summary of the Judgment

The Court of Appeal allowed the appeal and substituted a sentence of 36 months’ detention in a young offender institution. It held that:

  • The Crown Court’s approach of adding months because the appellant was an adult at sentence was “entirely unjustified”.
  • The correct guideline analysis produced a higher starting point than the judge used, but substantially greater allowance should have been made for personal mitigation and (where attributable to the prosecution) delay.
  • The court warned against double counting: if business/third-party harm is used to justify the harm category or starting point, it cannot also be re-used as an aggravating feature.

3) Analysis

3.1 Precedents Cited

The judgment does not cite prior case authorities by name. Its reasoning is anchored in orthodox sentencing principles and the structured application of the Sentencing Council Robbery Guideline (and, implicitly, established approaches to: (i) sentencing children/young people by reference to their age at the time of offending, and (ii) avoiding double counting within the guideline framework).

3.2 Legal Reasoning

a) Guideline categorisation and starting point

The sentencing judge treated the robbery as falling between guideline categories and adopted a starting point of 5 years 6 months. The Court of Appeal disagreed and concluded the proper starting point was 6 years 6 months (78 months), reflecting (i) the serious psychological impact on the shop assistant and (ii) the financial harm caused to the shop owner. Importantly, the court accepted that business harm can be relevant at the harm-assessment stage, but it triggers a key constraint: it must not be counted again as an aggravating factor.

b) Double counting: harm versus aggravation

The Court of Appeal made an explicit methodological correction: where harm to a shop owner/business is used to inform the harm category (and thus the starting point), it cannot then also be treated as a statutory aggravating feature. This is a practical application of the broader rule that the same feature should not inflate sentence twice under different headings.

c) Youth at the time of offence: the correct adjustment

The sentencing judge reduced the starting point by about one-third to reflect the appellant’s age (17) at the time of the offence. The Court of Appeal endorsed that reduction, observing it was “if anything, generous”. This affirms that, even where the offence is grave, youth remains a central sentencing consideration because it bears on culpability, maturity, and prospects of rehabilitation.

d) Adult at sentence: no “uplift” after youth discount

Having reduced for youth, the Crown Court then increased the term to reflect that the appellant was an adult at sentence. The Court of Appeal rejected this outright: age at sentence cannot justify an increase where the offence was committed as a child. The judgment treats the relevant age for culpability assessment as the age at offending, not the age when the case is eventually concluded.

e) Delay and personal mitigation

The Court of Appeal held that the appellant’s personal mitigation justified a “significant reduction” beyond the youth adjustment, including: previous good character, constructive steps/qualifications, low assessed risk, remorse, and lack of further offending. It also accepted that delay may warrant some reduction insofar as it is attributable to the prosecution rather than the offender.

f) Guilty plea credit

The appellant received 15% credit for the guilty plea; the Court of Appeal did not interfere with this, indicating the allowance was within proper bounds given the stage at which the plea was entered.

g) The Court of Appeal’s recalculation

The court set out a transparent step-by-step recalculation:

  1. Starting point: 78 months (6 years 6 months)
  2. Youth reduction (one-third): down to 52 months
  3. Further reduction for other mitigation: down to 43 months
  4. 15% plea credit and rounding: final sentence 36 months

The substituted sentence was therefore 10 months shorter than that imposed below, notwithstanding the Court of Appeal’s view that the correct guideline starting point was actually higher than the sentencing judge selected.

3.3 Impact

  • Child-offender principle safeguarded against procedural delay: The decision prevents a child offender from being penalised simply because proceedings conclude after they turn 18. Sentencers should not “claw back” a youth reduction by adding time due to adult status at sentence.
  • Sharper discipline in guideline arithmetic: The explicit warning on double counting (harm to the business used once only) is likely to be cited in robbery and shop-related offending where courts may be tempted to treat the same commercial impact as both harm and aggravation.
  • Appellate willingness to revise starting points despite party agreement: The court was not constrained by the parties’ shared view of categorisation and was prepared to identify a higher correct starting point, while still reducing the ultimate sentence through proper mitigation analysis.

4) Complex Concepts Simplified

Starting point
The guideline “baseline” sentence for the offence category before adjustments for aggravating/mitigating factors and guilty plea.
Culpability and harm categories
Guidelines classify offending by seriousness: “culpability” reflects blameworthiness (e.g., weapon, planning), and “harm” reflects impact (e.g., fear, injury, financial loss).
Youth reduction
A reduction recognising that children and young people typically have less mature judgment and greater capacity for change, lowering culpability compared to adults.
Double counting
Using the same fact twice to increase sentence—e.g., treating business losses as part of “harm” to select a higher starting point and then adding further time again because of the same losses as an “aggravating factor”.
Plea credit
A percentage reduction for pleading guilty, reflecting saved court time and (often) reduced distress to witnesses; the percentage depends on timing.

5) Conclusion

[2026] EWCA Crim 594 reinforces two practical sentencing rules in child-committed robberies sentenced later: (1) culpability is anchored to age at offending, so turning 18+ by sentence does not justify an uplift after applying a youth discount; and (2) courts must avoid double counting the same business impact across harm assessment and aggravation. The judgment also exemplifies the Court of Appeal’s readiness to correct guideline methodology while ensuring that genuine personal mitigation is given meaningful effect.
