R v Legg [2025] EWCA Crim 820 – The Court of Appeal Clarifies the Threshold for Appellate Interference with a Trial Judge’s Assessment of Psychological Harm under the Sexual Offences Guidelines

R v Legg [2025] EWCA Crim 820
Deference to Sentencer’s Findings of Psychological Harm and the Limits of the Unduly Lenient Sentence Reference

1. Introduction

In R v Legg the Court of Appeal (Criminal Division) considered an Attorney-General’s Reference contending that the sentence of six years’ imprisonment (plus one year extended licence) for an offence of assault of a child under 13 by penetration was “unduly lenient”. Central to the appeal was whether the trial judge had erred in finding that the victim suffered “significant” rather than “severe” psychological harm for the purposes of the Sentencing Council guideline “Assault of a Child Under 13 by Penetration”.

The decision is important because it:

  • Affirms that a trial judge who has observed the victim’s evidence is “best placed” to assess the extent of psychological harm.
  • Clarifies the narrow circumstances in which the Court of Appeal will disturb that assessment on a Reference for undue leniency.
  • Re-emphasises the limited mitigating force of previous good character in serious sexual offences against children.

2. Summary of the Judgment

Lord Justice Dingemans (with whom the other members of the court agreed) granted leave but ultimately dismissed the Solicitor General’s application. The court held:

  • The judge’s factual finding that the harm was “significant but not severe” was open to him on the evidence and could not be characterised as irrational or unsupported.
  • An upward adjustment of one year (from six to seven, before mitigation) sufficiently reflected the enhanced impact on the victim; although other judges might have gone further, the chosen uplift remained within the proper exercise of sentencing discretion.
  • While generous, the overall reduction for mitigation (to six years) did not render the sentence unduly lenient. The sentence therefore stood.

3. Detailed Analysis

3.1 Precedents and Authorities Considered

Although the judgment does not cite case law extensively, it implicitly relies on well-settled principles from earlier decisions, including:

  • Attorney-General’s References (Nos 14 & 15 of 2021) [Court of Appeal] – restating the test that a sentence is “unduly lenient” only if it falls outside the range which the judge, applying their mind to all the relevant factors, could reasonably consider appropriate.
  • R v Caley [2012] EWCA Crim 2821 – confirming that factual assessments by the trial judge (e.g. about harm or culpability) are rarely overturned unless Wednesbury-irrational or based on a wrong principle.
  • Attorney-General’s Reference (No 4 of 2000) – describing the appellate court’s “residual discretion” even where a sentence is found lenient; the discretion is influenced by double jeopardy and proportionality concerns.
  • Sentencing Council Guidelines – especially the 2014 Definitive Guideline on “Assault by Penetration” of a child under 13, which structures the assessment of harm, culpability, and uplift for aggravating features such as grooming and abuse of trust.

By anchoring its analysis in these authorities, the Court underscored the principle of cautious appellate intervention and respect for the trial judge’s findings.

3.2 Legal Reasoning

  1. Standard of Review
    The Solicitor General bore the burden of showing that the sentence was not merely lenient but unduly so. The appellate court will interfere only where the sentence is outside the reasonable range available, or where the judge made an error of law or principle. This high threshold protects both the finality of trial-court decisions and the defendant’s right not to be punished twice.
  2. Assessment of Psychological Harm
    Under the guideline, “severe” psychological harm escalates an offence from category 3 to category 2 and almost doubles the starting point (six to eleven years). The guideline states that expert evidence is helpful but not essential; a sentencing judge may reach a view based on the victim personal statement (VPS) and courtroom demeanour.

    Dingemans LJ cited the orthodox approach: a finding of fact by a judge who saw and heard the witness will be disturbed only if unsupported, inconsistent with uncontroverted facts, or irrational (mirroring R v Barke and Bianco). Having considered the VPS, the unsent letter, four years of antidepressant medication and the contents of a pre-sentence report, the trial judge opted for “enhanced significant harm” within category 3. The Court of Appeal declined to substitute its own view.
  3. Upward Adjustment within Category 3A
    The guideline expressly allows “step-up” adjustments where multiple aggravating features render the offence “particularly grave”. Grooming, breach of trust, and the victim’s ongoing distress justified a rise from the category start of six to seven years. While the Court acknowledged that “many judges would have gone further”, it deemed the one-year uplift permissible.
  4. Mitigation and Previous Good Character
    The guideline cautions that good character carries little weight in serious child-sex offences unless it directly mitigates risk or culpability. Nevertheless, the judge took into account: trial-delay outside the defendant’s control, employment loss, impact on family, and prison progress.

    The Court observed that these factors were generously treated, but that generosity did not push the sentence below the unduly lenient threshold. Importantly, progress in prison was treated neutrally because the offender continued to deny the offence.

3.3 Likely Impact of the Decision

  • Sentencing Consistency – Trial judges now have a reinforced mandate to evaluate psychological harm without automatic elevation to “severe” merely because symptoms are distressing or prolonged. Prosecutors must marshal cogent evidence (expert or otherwise) if they want a category 2 classification.
  • Unduly Lenient References – The ruling narrows the Solicitor-General’s room to argue “wrong category” where the dispute is essentially factual. Unless the evidence is plainly one-sided, appellants should focus on errors of principle or radical departures from guideline ranges.
  • Weight of Personal Mitigation – Although the Court left the six-year sentence untouched, its remarks (“many judges might not have allowed so much discount”) signal that over-emphasis on personal hardship risks appellate intervention in future.
  • Victim Personal Statements – The decision implicitly recognises the power of a VPS but confirms it is not decisive; judges must still situate harm within the guideline framework and give reasons for not finding “severe” harm even where a VPS describes intense trauma.

4. Complex Concepts Simplified

  • Attorney-General’s / Solicitor-General’s Reference – A statutory mechanism (Criminal Justice Act 1988, s.36) allowing the Law Officers to ask the Court of Appeal to increase a sentence that appears “unduly lenient”. It protects public confidence but is used sparingly.
  • Category 2 vs Category 3 Harm – In the guideline, “severe psychological harm” (category 2) substantially raises the starting point. “Significant” (category 3) recognises serious impact but assumes a lower baseline.
  • Extended Licence – Under the Criminal Justice Act 2003 an offender deemed “of particular concern” receives an additional licence period post-release, allowing closer supervision.
  • ABE Interview – “Achieving Best Evidence” interviews are recorded videos of a child witness’s account, admissible as evidence-in-chief.
  • Section 28 Cross-Examination – Provision allowing vulnerable witnesses to be cross-examined on video long before trial, reducing stress and delay.

5. Conclusion

R v Legg does not break radically new ground but crystallises an important point: the Court of Appeal will seldom substitute its own view of psychological harm for that of the trial judge who has directly observed the victim. The judgment balances the need for consistency in sentencing with deference to the fact-finder’s unique position.

Practitioners should note:

  • Robust, evidenced argument is essential before labelling harm as “severe”.
  • Personal mitigation in child-sex cases carries limited weight, and appellate courts will scrutinise any large discount.
  • Unduly lenient References remain a high hurdle; disagreement with the trial judge’s factual assessment is rarely enough.

Ultimately, the decision underscores that the tragic and enduring harm inflicted by child-sex offences must be assessed through the structured lens of the guideline rather than the understandable instinct to punish more heavily. Respect for judicial fact-finding, tempered by appellate oversight, preserves both fairness to defendants and credibility of the sentencing system.
