Transparent Youth-Mitigated Sentencing: Court of Appeal Clarifies the Need to Explain “Notional Adult” Terms and Reductions in Serious Domestic Sexual Offending

1. Introduction

In R v Cathrae [2026] EWCA Crim 1062, the Court of Appeal (Criminal Division) (Coulson LJ, Farbey J, HHJ Lickley KC) considered an appeal against a sentence of 10 years’ detention in a young offender institution imposed for a cluster of offences committed within an abusive intimate relationship.

The appellant (now 21) committed offences between ages 17 and 20 against his former partner (C1) and also targeted a child relative (C2). The convictions comprised: controlling/coercive behaviour; rape; two counts of assault by penetration; suffocation; witness intimidation; and harassment putting a person in fear of violence. The complainant’s lifelong anonymity was engaged under the Sexual Offences (Amendment) Act 1992.

The appeal raised three principal issues:

  • whether the overall 10-year term was insufficiently explained (in particular, how youth/other mitigation reduced any “notional adult” sentence);
  • whether the term was manifestly excessive given age, immaturity and mental health conditions;
  • whether indefinite restraining orders protecting C1 and C2 were impermissible or inappropriate.

2. Summary of the Judgment

The Court of Appeal dismissed the appeal.

  • It agreed that the sentencing remarks were unsatisfactory because they did not explain the arithmetic of the 10-year term or the precise reduction for youth and other mitigation.
  • However, undertaking a limited re-sentencing exercise, it concluded that:
    • the notional adult overall term would have been at least 15 years (10 years for rape (Category 2A) plus a significant uplift for the wider conduct);
    • a 33% reduction for youth and mitigation was appropriate; and
    • that yielded 10 years, matching the sentence imposed—therefore the sentence was not wrong in principle nor manifestly excessive.
  • The Court upheld the indefinite restraining orders, emphasising the high assessed risk and the practical impossibility of choosing a safe fixed duration. It noted the appellant could apply later to vary or discharge the orders if risk changed.

3. Analysis

3.1 Precedents Cited

The judgment did not cite specific authorities by name. It referred generally to “a good deal of authority” supporting a youth-based reduction in the range of one-third to one-half. The court’s reasoning instead anchored itself in:

  • the applicable Sentencing Guidelines for rape (including categorisation and starting points); and
  • established sentencing methodology (lead offence; uplift for additional criminality; concurrency/consecutivity; and principled credit for youth).

3.2 Legal Reasoning

(a) Lead offence selection and “stepping back”

The Court endorsed taking rape as the lead offence and then “uplifting” to reflect the totality of the remaining offending (extended coercive control, assaults by penetration, suffocation, intimidation and harassment). It also regarded the decision to make other sentences concurrent as generous, noting the judge could have imposed consecutive terms, particularly for intimidation and harassment of C2.

(b) The error identified: inadequate explanation, not necessarily excessive length

The Court’s central criticism was transparency: the sentencing remarks did not show (i) the “notional adult” term and (ii) the precise discount for youth/other mitigation. That omission, the Court held, was “unsatisfactory” and created the need for appellate intervention.

Importantly, the Court did not treat the deficiency as automatically requiring a reduction; rather, it justified a limited resentencing to test whether the result was supportable on a correct approach.

(c) Reconstructing the correct sentencing structure

The Court reconstructed the sentence in three steps:

  1. Rape guideline starting point (adult): Category 2A with a starting point of 10 years.
  2. Totality uplift (adult): the other offences (especially pervasive coercive control and repeated penetrative assaults) warranted an uplift of at least 5 years, producing a notional adult term of 15 years or more. The Court noted that 15 years is also the guideline starting point for the next higher rape category, reinforcing that the uplift was principled.
  3. Youth/mitigation discount: a 33% reduction was selected as appropriate on the facts, yielding 10 years.

(d) Youth and mental health: avoiding “double counting”

The appellant relied on immaturity and multiple mental health conditions (including autism spectrum disorder and ADHD, with substance-related disorders described in expert material) to argue for a larger reduction.

The Court declined further reduction for three linked reasons:

  • Overlap with youth: many difficulties were “bound up” with age and immaturity; further reduction risked double counting.
  • Responsibility and narrative: the record suggested the appellant had, at times, used diagnoses as an excuse for violence (as reflected in what he told C1).
  • Gravity and persistence: the sustained and serious nature of the abuse meant additional discount would make the sentence too lenient.

(e) Dangerousness and the “extended sentence” observation

The Court highlighted the pre-sentence assessment that the appellant was dangerous and remarked he was “fortunate” not to have received an extended sentence. However, it stated it was not in a position to impose an extended sentence because none had been imposed below.

The practical significance is twofold: (i) the dangerousness finding supported the robustness of the 10-year term, and (ii) it framed the protective rationale for long-lasting ancillary orders.

(f) Indefinite restraining orders

Upholding the indefinite restraining orders, the Court reasoned that where risk is assessed as high and the future trajectory is uncertain, a fixed term is inherently arbitrary. The Court emphasised a safeguard: the appellant may apply later to vary or discharge the order if circumstances change.

3.3 Impact

  • Sentencing transparency: the decision reinforces that where courts apply youth/immaturity discounts—especially after an uplift for multiple offences— sentencing remarks should plainly identify the notional adult term and the discount applied. A sound sentence may still be upheld, but poor explanation can trigger an appeal and an appellate reworking.
  • Structured totality in domestic sexual abuse: the judgment illustrates an appellate-ready method: lead offence + principled uplift reflecting the coercive-control context + calibrated youth reduction.
  • Mental health mitigation limits: where conditions substantially overlap with youth or are not clearly causative of offending, courts may resist additional reduction, particularly in sustained and degrading abuse.
  • Indefinite protection orders: the judgment supports indefinite restraining orders where risk cannot sensibly be time-boxed, with variation/discharge as the mechanism for future review.

4. Complex Concepts Simplified

  • Category 2A (rape guideline): “Category 2” reflects harm/culpability at a serious (but not top) level; “A” denotes higher culpability features (here, abuse of trust and prior violence). The category fixes the guideline starting point (10 years for an adult).
  • Lead offence and uplift: instead of mechanically adding sentences for every count, courts often pick the most serious offence, then increase the term to reflect the total criminality.
  • Concurrent vs consecutive: concurrent sentences run at the same time; consecutive sentences stack one after another, increasing the total.
  • Totality principle (“step back”): after calculating component parts, the judge checks the overall sentence is just and proportionate.
  • Double counting: giving the same mitigating factor “credit” twice (e.g., treating immaturity and closely related developmental/behavioural features as separate discounts).
  • Extended sentence: a sentence structure used for dangerous offenders that can extend time under licence/supervision beyond the custodial term.
  • Indefinite restraining order: an order without an end date, designed to protect victims where risk may persist; it can later be varied or discharged by the court on application.

5. Conclusion

R v Cathrae [2026] EWCA Crim 1062 confirms that even where a sentencing outcome is substantively correct, courts should clearly explain (i) the “notional adult” sentence after totality uplift and (ii) the precise reduction for youth and mitigation. Applying that structured approach, the Court of Appeal held that a notional adult term of about 15 years, reduced by 33% for youth/mitigation, properly produced the 10-year detention term—so the sentence was neither wrong in principle nor manifestly excessive. The Court also endorsed indefinite restraining orders where high risk makes a fixed term speculative, leaving variation/discharge as the appropriate future safeguard.
