Non‑mechanistic application of Schedule 21 youth murder starting points and “ought to be obvious” culpability for child manslaughter offenders

Case: VGT & Ors [2026] EWCA Crim 919 (CACD)
Procedure: Reference by the Solicitor General under s.36 Criminal Justice Act 1988 (unduly lenient sentences)
Court: England and Wales Court of Appeal (Criminal Division)
Date: 1 June 2026

1. Introduction

Three child offenders (identified by ciphers due to reporting restrictions) were tried in the Crown Court at Manchester and convicted following the killing of a 14‑year‑old victim in a street confrontation. One offender (XGV) was convicted of murder; the other two (VGT and WGU) were convicted of manslaughter.

The sentencing judge imposed:

• XGV: detention at His Majesty’s Pleasure under s.259 Sentencing Act 2020, with a minimum term of 11 years and 42 days (after remand credit).
• VGT: 2 years 10 months’ detention under s.250 Sentencing Act 2020.
• WGU: 2 years 4 months’ detention under s.250 Sentencing Act 2020.

The Solicitor General sought leave to refer all three sentences as “unduly lenient”. The Court of Appeal refused leave on every sentence.

Reporting restrictions and open justice

The Court confirmed continuation of reporting restrictions for the child offenders, applying the open‑justice/welfare balancing approach in R v RKL [2021] EWCA Crim 200.

2. Summary of the judgment

• Murder minimum term (XGV): The Court held that the sentencing judge was entitled to begin at the Schedule 21 paragraph 5A starting point (13 years for offenders aged 14 and under) and then adjust for aggravating and mitigating factors, including substantial mitigation linked to immaturity and vulnerability. Being near the top of the age bracket did not require an automatic uplift.
• Manslaughter (VGT and WGU): The Court held the judge did not err by placing culpability in category C (rather than category B) of the adult unlawful act manslaughter guideline when used only indirectly through the Sentencing Council’s guideline for children and young people. What “ought to have been obvious” could not be imported from adult standards without accounting for childhood and maturity.
• Outcome: Leave refused; sentences not increased.

3. Analysis

3.1 Precedents cited

• R v RKL [2021] EWCA Crim 200
  Used to justify continuation of reporting restrictions by weighing open justice against the welfare of child offenders. The Court treated anonymity as a welfare protection measure where press participation was absent and the balance favoured restriction.
• BGI and CMB [2024] EWCA Crim 1591
  Central to the reference on XGV’s minimum term. BGI reaffirmed that the paragraph 5A starting point for children “must not be applied mechanistically” across the entire age band. The Solicitor General relied on this to argue for an uplift for a child near 15; the Court used the same authority to stress flexibility and individualised assessment, rejecting any mandatory uplift logic.
• R v Jones [2005] EWCA Crim 315
  Quoted (via BGI) for the foundational proposition that Schedule 21 starting points are guidance, not a straitjacket; they must not be used “mechanistically”, and detailed aggravation/mitigation can justify any minimum term length.
• Kamarra-Jarra [2024] EWCA Crim 198
  Cited to reinforce that Schedule 21 starting points are to be applied flexibly “so as to achieve a just result”, supporting the Court’s refusal to impose formulaic adjustments based solely on chronological position within an age band.

3.2 Legal reasoning

(A) The Attorney General’s Reference framework

A reference under s.36 Criminal Justice Act 1988 is not an appeal against sentence as of right; it is a public law mechanism to correct unduly lenient sentences. The Court’s task is not to substitute its own view merely because it might have sentenced differently, but to identify legal error or a sentence falling outside the reasonable range.

(B) XGV: applying paragraph 5A of Schedule 21 (youth murder)

The prosecution’s complaint was narrow: once the 13‑year starting point for offenders aged 14 and under was identified, the judge should have moved up because XGV (aged 14) was at the top of that age bracket.

The Court rejected the premise. Drawing on BGI and CMB, it emphasised that “non‑mechanistic” application cuts both ways:

• Paragraph 5A does not require incremental uplifts within the age band.
• Children’s maturity varies; a 14‑year‑old may be significantly immature, and a younger child may be comparatively mature.
• The correct approach is individualised sentencing, where chronological age is considered alongside emotional/developmental maturity and other personal mitigation.

On the facts, the judge’s approach was orthodox: identify the statutory starting point; mark aggravation (public place, pursuit, previous knife caution, limited concealment); then apply substantial mitigation (immaturity, cognitive limitations and ADHD, adverse childhood experiences, modern slavery/vulnerability, and progress/remorse). The Court found no error of principle and therefore no basis to find the minimum term unduly lenient.

(C) VGT and WGU: consulting adult manslaughter guidelines for child offenders

The Solicitor General’s case was that the judge wrongly placed culpability in category C rather than category B of the adult unlawful act manslaughter guideline, contending it must have been “obvious” (or ought to have been obvious) that a knife created a high risk of death or very serious harm.

The Court’s reasoning turned on two linked constraints:

• Indirect use only: The unlawful act manslaughter guideline is an adult guideline. Under the Sentencing Council’s Sentencing Children and Young People Guideline (paragraphs 6.45–6.46), the court may consult the adult guideline only as a preliminary step once custody is inevitable, then apply a substantial, non‑mechanistic reduction sensitive to maturity.
• Child‑specific culpability lens: The phrase “was or ought to have been obvious to the offender” cannot simply be assumed to carry the same content for children as for adults. The judge had to evaluate what these particular child offenders, in this fast‑moving confrontation, with their ages and maturity, ought to have appreciated about the risk posed by the principal offender’s conduct.

Importantly, the Court noted the sentencing judge had engaged with the competing submissions and had been uniquely placed to assess culpability, having seen the trial evidence and one offender’s testimony. The jury’s verdicts—acquitting both boys of the more serious offence—formed part of the context within which their secondary culpability for the killing was assessed.

The Court therefore held that selecting category C as the “nearest guidance” was open to the judge and disclosed no legal error. With no other grounds advanced, the reference failed.

3.3 Impact

• Schedule 21 youth murder sentencing: The decision reinforces that courts are not to “index” minimum terms within paragraph 5A by the child’s position in the age range. Parties seeking uplifts (or reductions) must focus on the child’s actual maturity and the full matrix of aggravation/mitigation.
• Adult guidelines in youth cases: The judgment provides clear appellate endorsement of a child‑centred interpretation of adult guideline language such as “ought to have been obvious”, limiting arguments that adult risk‑awareness standards can be transplanted onto children without adjustment.
• Unduly lenient references: The case exemplifies the narrowness of s.36 review: absent a demonstrable error of principle (or a sentence outside the reasonable range), the Court will not intervene even in grave offences with profound victim impact.

4. Complex concepts simplified

• “Unduly lenient” (s.36): Not “lenient” in an everyday sense. It means a sentence so low that it falls outside the range a reasonable judge could impose, usually because of legal error or misapplication of guidelines.
• Detention at His Majesty’s Pleasure (s.259 Sentencing Act 2020): The mandatory sentence for a child convicted of murder. The court sets a minimum term (similar to a tariff) after which release may be considered; it is not automatic release.
• Schedule 21 starting points: Statutory “anchors” for the minimum term in murder cases. They guide the court but do not dictate the final minimum term; the court must then weigh aggravating and mitigating factors.
• “Must not be applied mechanistically”: A warning against rigid formulae (e.g., automatic uplifts or reductions) that ignore the individual facts and the offender’s personal circumstances.
• Unlawful act manslaughter culpability categories: In the adult guideline, category B generally captures higher culpability where the unlawful act carried an obvious (or ought‑to‑be‑obvious) high risk of death/GBH. Category C reflects lower culpability. In youth cases, those concepts must be translated through the child‑sentencing framework.

5. Conclusion

VGT & Ors [2026] EWCA Crim 919 consolidates a principled, child‑specific approach to serious youth sentencing. It confirms that paragraph 5A Schedule 21 starting points are flexible tools rather than automatic escalators within an age band, and it cautions against reading adult culpability language—especially “ought to have been obvious”—as if children are held to adult standards of risk appreciation. The Court’s refusal to grant leave under s.36 underscores the deference owed to careful first‑instance sentencing decisions where the correct framework has been applied and the outcome lies within the reasonable sentencing range.
