R v Clark [2025] EWCA Crim 931
Disposal of the Weapon as an Independent Aggravating Factor and Administrative Correction of Youth Sentencing Defects

Introduction

R v Clark is a renewed application for leave to appeal against sentence heard by the Court of Appeal (Criminal Division) on 1 July 2025. The applicant, aged 20 at sentence, had been convicted at Chelmsford Crown Court of:

• Manslaughter of Andy Wood (16);
• Assault occasioning actual bodily harm on “C” (17); and
• Breach of a suspended sentence order for carrying a bladed article.

Sweeting J imposed 13 years’ detention in a Young Offender Institution (YOI) for the manslaughter and 18 months concurrent for the assault, together with activation of two months of the suspended sentence (also concurrent).

The appeal focused on two broad issues:

1. Whether 13 years was manifestly excessive in the light of the guideline for manslaughter and the factual matrix; and
2. Whether a slip in pronouncing “imprisonment” (which is unlawful for a defendant under 21) rendered the sentence invalid.

The Court refused leave, but in doing so clarified two important points which now stand as guidance for future sentencing:

1. Disposal of a weapon after an unlawful killing can constitute a distinct and weighty aggravating factor, even where the defendant was not proven to have brought the weapon to the scene.
2. Where the sentencing judge inadvertently labels YOI detention as “imprisonment”, the Court of Appeal may simply direct amendment of the record rather than allow the appeal, following R v Stocker.

Summary of the Judgment

The Court (presided over by Lord Justice Holgate) held:

• The trial judge placed the offence correctly in culpability Category B of the manslaughter guideline with a 12-year starting point (range 8–16).
• The assessed aggravating factors (child victim, size disparity, sustained attack, use and disposal of knife, public location, offending under suspension) outweighed the mitigating factors (age, immaturity, troubled background, remorse).
• Even if aggravating and mitigating factors were in parity, the concurrent assault and breach justified an uplift under the Totality guideline.
• 13 years lay “comfortably within the range” and was not manifestly excessive; another judge could have gone higher.
• The pronouncement of “imprisonment” for a defendant under 21 was a technical error. Consistent with R v Stocker the Court cured the error by ordering amendment of the Crown Court record, avoiding the need to quash and re-pass sentence.
• The anonymity order under s.45A YJCEA 1999 for the two young civilian witnesses remains in force.

Analysis

Precedents Cited

• R v ZA [2023] 2 Cr App R (S): guidance on giving proper weight to youth and immaturity, stressing the developing maturity of those under 25.
• R v Stocker [2013] EWCA Crim 1993; [2014] 1 Cr App R 18: establishes that purely technical errors in pronouncement (e.g., mis-labelling custodial sentences) can be corrected administratively on appeal without quashing the sentence.
• Totality Guideline (Sentencing Council, 2023 revision): sets out how multiple offences and breached orders should be reflected in the overall sentence.
• Sentencing Council’s Manslaughter Guideline (in force since 2018), particularly Paragraphs 35–48 on unlawful act manslaughter and Culpability Categories A–D.

No earlier case expressly identified post-offence disposal of a weapon as an independent aggravator in unlawful act manslaughter; the Court’s emphasis therefore adds new weight to that conduct.

Legal Reasoning

1. Deference to Trial Judge’s Findings – Because sentencing is highly fact specific, the Court of Appeal intervenes only where there is an error of principle or manifest excess. Sweeting J, having presided over the trial, was best placed to assess the factual background and credibility of the two competing narratives.
2. Placement within Guideline Framework – The fatal stabbing to the neck with a large knife created an obvious risk of death. Category B was therefore inevitable and Mr Etherington KC did not challenge that categorisation.
3. Aggravating Features Analysed
   • Age and vulnerability of deceased – 16 years, physically smaller.
   • Sustained attack – multiple injuries inflicted in a brief period.
   • Public place – night-time park increases public fear, jeopardises passers-by.
   • Breach of suspended sentence – statutory aggravator under s.65 Sentencing Act 2020.
   • Disposal of weapon – hindered investigation, deprived court and jury of potent evidence, thus aggravating.
4. Mitigating Features Evaluated – Youth (20), lack of similar previous violence, troubled upbringing, remorse, realistic prospect of rehabilitation.
5. Totality Principle – Even if balanced, the concurrent ABH and breach justified an uplift beyond the 12-year starting point to 13 years.
6. Technical Sentencing Error – s.227 Sentencing Act 2020 prohibits “imprisonment” for those under 21. Consistent with Stocker, a clerical correction sufficed; the merits of the substantive sentence were unaffected.

Impact of the Judgment

The decision is likely to influence three areas of criminal practice:

1. Weapon Disposal as Aggravation – Future sentencing for bladed-weapon manslaughter or grievous bodily harm is likely to treat post-offence disposal of the weapon as a distinct aggravating circumstance, regardless of who originally brought the weapon.
2. Youth Custody Technicalities – Trial judges and court clerks are reminded to use “detention in a YOI” rather than “imprisonment” for defendants under 21. Where the error occurs, Courts of Appeal can correct it without quashing the sentence, minimising unnecessary relisting.
3. Totality in Mixed Offending – The case illustrates how concurrent sentences for lesser offences and breaches can still necessitate an uplift on the primary sentence, even where the aggravation/mitigation balance for that primary offence is neutral.

Complex Concepts Simplified

• Manslaughter vs Murder: Murder requires intent to kill or cause really serious harm; manslaughter (here “unlawful act manslaughter”) occurs when the defendant commits a dangerous, unlawful act that unintentionally causes death.
• Culpability Categories (A–D): Sentencing Council’s tiers reflecting seriousness. Category A is highest (very high culpability); Category B is “high” but not the most flagrant.
• Totality Principle: Ensures the overall sentence for multiple offences is just and proportionate; courts ask “What is the total criminality and what is the least sentence to reflect it?”
• Suspended Sentence Order: Custodial sentence whose enforcement is delayed (“suspended”) subject to compliance; breach usually triggers activation of the suspended term.
• Young Offender Institution (YOI): Custodial facility for 18–20-year-olds; by statute a defendant under 21 cannot be sentenced to “imprisonment”.
• Manifestly Excessive: Standard of appellate review. A sentence may be harsh yet within permissible range; “manifestly excessive” means it clearly falls outside the reasonable range of sentences open to the judge.
• Section 45A YJCEA 1999 Order: Grants lifetime anonymity to child witnesses/victims in criminal proceedings, preventing publication of identifying details.

Conclusion

R v Clark reinforces the breadth of judicial discretion within the Sentencing Council’s manslaughter guideline while spotlighting two specific sentencing principles:

1. Deliberate disposal of a weapon post-offence is capable of significant additional aggravation, even absent proof that the offender armed himself in advance.
2. Technical mis-labelling of YOI sentences as “imprisonment” can be cured by simple amendment under the Stocker approach, avoiding unnecessary appellate intervention.

Practitioners should therefore advise clients that attempts to hinder investigation, such as discarding the weapon, will likely attract substantial sentence increases. Courts are equally reminded to scrutinise sentencing language for statutory compatibility with the defendant’s age but can rely on administrative correction where slips occur.

Overall, the decision underscores the Court of Appeal’s reluctance to interfere with fact- sensitive sentencing determinations absent clear error, while subtly expanding the catalogue of aggravating factors relevant to knife-related homicides.
