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:
- Starting point: 78 months (6 years 6 months)
- Youth reduction (one-third): down to 52 months
- Further reduction for other mitigation: down to 43 months
- 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.
