Assault by Penetration: Significant Injury and Violence Beyond the Act Requires Category 2 Harm (Starting Point 6 Years)

1. Introduction

R. v NEL ([2025] EWCA Crim 1750) is an unduly lenient sentence reference brought by His Majesty’s Solicitor General under section 36 of the Criminal Justice Act 1988. The offender (anonymised to protect the complainant’s anonymity via the parties’ child) was convicted after trial of:

  • Count 1: Assault by penetration, contrary to section 2 of the Sexual Offences Act 2003.
  • Count 2: Unlawful wounding, contrary to section 20 of the Offences Against the Person Act 1861.

He was acquitted of intentional strangulation (count 3) contrary to section 75A of the Serious Crime Act 2015. The Recorder imposed a total of 2 years’ imprisonment (2 years on count 1; 1 year concurrent on count 2).

The appeal turned on a single sentencing issue: whether the assault by penetration fell within “category 2” harm or only “category 3” harm under the relevant sentencing guideline. The categorisation mattered because it dictated the correct starting point and therefore whether the 2-year term was outside the proper sentencing ambit.

2. Summary of the Judgment

The Court of Appeal (Criminal Division) (Edis LJ, Vice President) held that the Recorder’s categorisation was wrong. On the evidence (including a medically confirmed 5 cm tear to the labia majora requiring surgical repair and additional violence such as biting), the offence necessarily involved violence beyond that inherent in the offence and significant physical harm. It should therefore have been treated as category 2 harm.

The Court quashed the original sentences and substituted:

  • Count 1: 5 years’ imprisonment (substituted).
  • Count 2: The concurrent term was left unaffected.

3. Analysis

3.1 Precedents Cited

No earlier case authorities are cited by name in the judgment. The Court’s reasoning instead proceeds by close application of:

  • The sentencing guideline framework for assault by penetration, including the harm-category escalators (e.g., “severe psychological or physical harm”, “sustained incident”, and “violence or threats of violence beyond that which is inherent in the offence”).
  • The Court also notes the relevance of the overarching guideline for offences involving violence in or after a relationship (raised below as aggravation in a domestic context), though the dispositive issue remained harm categorisation.

The absence of named precedents makes the decision particularly guideline-centric: it illustrates the Court’s willingness, on a section 36 reference, to intervene where the sentencing judge misapplies guideline harm factors or fails to explain a departure from the factual basis supported by the verdict and evidence.

3.2 Legal Reasoning

The Court’s reasoning has four main steps.

(a) The “one simple question”: category 2 or category 3 harm

The Court framed the reference as turning on a single point: whether the Recorder was entitled to treat the case as category 3 harm or whether the facts required categorisation as category 2 harm. That framing is important: it emphasises that the legality of the sentencing outcome depended on the correctness of the guideline entry-point, not merely a disagreement about the final number.

(b) Sentencing on the basis of the evidence and verdict—especially where the judge gives no reasons for rejecting it

The Recorder made no express findings resolving disputes relevant to sentence (e.g., uninvited entry) and did not state that he rejected the complainant’s account. The Court held that, in those circumstances—particularly where the account was supported by medical evidence—the proper course was to sentence on the basis that the offender committed the offences as described by the complainant to the extent consistent with the convictions.

The acquittal on strangulation did not, in the Court’s view, justify treating other parts of the complainant’s account as rejected; it simply meant intentional strangulation was not proved to the criminal standard.

(c) Why category 2 harm was “required” on these facts

Applying the guideline’s category 2 harm factors, the Court identified two features as decisive:

  • “Sustained incident”: even on the offender’s own interview account, the non-consensual physical interaction lasted 10–15 minutes; the complainant described multiple episodes of digital penetration separated by pauses.
  • “Violence beyond that inherent in the offence” / significant physical harm: the medically evidenced neck biting and, crucially, the 5 cm labial tear requiring suturing under anaesthesia demonstrated a level of force beyond what is inherent in penetration. The Court treated the injury as compelling proof of category elevation.

Because these category 2 features were established on the evidence, the Court concluded the Recorder took the wrong starting point.

(d) Correct starting point and the recalibration to 5 years

For category 2B, the Court identified the guideline starting point of 6 years (range 4–9 years). It then assessed mitigation, including:

  • Taking the victim for medical treatment after the offence;
  • Good work record and “diligent way of life”;
  • Lack of relevant previous convictions.

The Court reduced the notional starting point from 6 to 5 years, but stressed that a 5-year term was “inescapable” given the seriousness of the attack. Notably, the violence used was treated as the principal aggravating factor, but also as a factor already embedded in the category 2 entry-point—an illustration of the guideline discipline against double counting.

(e) Procedural observation: dangerousness and pre-sentence reports

Although dangerousness was not re-opened on the reference, the Court made a pointed best-practice observation: where an offender is convicted of offences within the dangerousness regime, a judge who is inclined to conclude the offender is not dangerous should usually ensure that conclusion follows a careful investigation, commonly assisted by a pre-sentence report. This is framed as a systemic sentencing practice point rather than a ratio on the outcome in this case.

3.3 Impact

The decision is likely to be cited (even if informally) for three practical propositions in sentencing sexual offences:

  • Injury-driven category elevation: where penetration causes significant genital injury requiring surgical repair, the offence will generally demand category 2 harm treatment because it evidences violence beyond the inherent act.
  • Findings discipline: if a sentencing judge proposes to sentence on a basis inconsistent with the complainant’s evidence that is broadly supported by the verdict and medical material, the judge should make clear findings and reasons. Absent that, appellate correction is more likely.
  • Section 36 enforcement of guideline structure: the Court will treat guideline miscategorisation as capable of rendering a sentence “unduly lenient” even where there is mitigation and even where offences are concurrent and factually intertwined.

In domestic contexts, the judgment also reinforces that the sexual-offence guideline analysis remains the primary engine of sentence; relationship context may aggravate, but serious injury and extraneous violence may already drive the case into a higher harm category.

4. Complex Concepts Simplified

  • “Unduly lenient sentence” (section 36): a mechanism allowing the Attorney General/Solicitor General to ask the Court of Appeal to increase a Crown Court sentence that falls outside the range a judge could reasonably impose.
  • “Starting point” and “category range”: sentencing guidelines provide a typical starting sentence for an offence category, and a permissible range around it. Judges adjust up or down for aggravating/mitigating factors and apply totality.
  • “Category 2B” harm: a guideline classification indicating a higher level of harm than category 3. In this judgment, it was triggered chiefly by sustained conduct and violence beyond the inherent penetration, evidenced by serious injury.
  • “Concurrent sentence”: sentences served at the same time. Here, the wounding sentence ran concurrently with the assault-by-penetration sentence.
  • “Dangerousness regime”: a statutory framework requiring courts, for certain offences, to consider whether the offender presents a significant risk of serious harm, potentially affecting sentence type/length. The Court highlighted the importance of a pre-sentence report when concluding “not dangerous.”

5. Conclusion

R. v NEL underscores that, in assault by penetration cases, serious genital injury and other violence beyond the act of penetration will ordinarily compel category 2 harm classification and the substantially higher guideline starting point that follows. The Court’s intervention illustrates that unduly lenient references will succeed where the sentencing judge adopts an unjustified harm category—especially where the judge gives no clear reasons for discounting the complainant’s account that is supported by medical evidence and the jury’s verdict.
