Sentencing Autonomy and Elevated Benchmarks for Predatory Child-Sexual Offences in Northern Ireland
Commentary on Costar v R [2025] NICA 37

1. Introduction

In Costar v R the Court of Appeal in Northern Ireland (Keegan LCJ, McCloskey LJ and McLaughlin J) dismissed an appeal against an eight-year determinate custodial sentence (four years’ custody, four years’ licence) imposed for an extensive catalogue of sexual offending against a child aged 13-15. The appeal turned solely on whether the sentencing judge’s starting point of 12 years (before a one-third credit for an early guilty plea) was “manifestly excessive”.

The case is significant because the Court:

• Re-affirmed its willingness to impose higher starting points than those typically observed in England & Wales for comparable conduct;
• Clarified that the England & Wales Sentencing Council Guidelines are neither binding nor necessarily persuasive in Northern Ireland, particularly where multiple offences are concerned;
• Endorsed the trajectory set in R v Hutton [2024] NICA 19 and R v GM [2020] NICA 49 toward robust sentencing for persistent child-sexual misconduct.

3. Detailed Analysis

3.1 Precedents Cited and their Influence

• R v Hutton [2024] NICA 19:
  • Two victims, breach of trust, high culpability/harm. Court approved an 18-year starting point (12 years after plea).
  • Costar relied on Hutton to validate double-digit starting points where multiple serious offences arise, even absent breach of trust.
• R v DM [2012] NICA 36:
  • Warned against rigid guideline ranges in sexual offences.
  • Cited to justify fact-sensitive sentencing discretion.
• R v GM [2020] NICA 49:
  • Highlighted legislative intent of the 2008 Order to increase deterrence and reflect societal revulsion.
  • Provided philosophical underpinning for tougher sentences.
• England & Wales comparisons (Pipe, B, Edmonds, A-G Ref 106/2014):
  • Defence relied on these sub-10-year sentences to argue for an 8-9-year starting point.
  • Court distinguished them: guidelines there assume a single count; Northern Ireland is entitled to adopt more punitive policy.

3.2 The Court’s Legal Reasoning

1. High Culpability & Harm: Grooming over three years, deception about age, large age disparity, penetrative acts, ejaculation without protection, creation and retention of indecent images. These factors placed the case “at the high end of the scale”.
2. Totality Principle: Judge could have run sentences consecutively (15+ years realistically), but opted for a global sentence of 12 years to reflect overall criminality.
3. Maxima and Headline Offences: Statutory maximums were 14 years (Articles 16 & 17 2008 Order) and 10 years (indecent images). A 12-year start, while “near” the ceiling, still allowed scope for worse cases.
4. Autonomy from English Guidelines: The Court reiterated that Sentencing Council ranges are a guide only, often premised on single-count scenarios, and cannot fetter local discretion where numerous counts and Northern Irish public policy demand sterner measures.
5. Deterrence and Moral Censure: Emphasis on protecting children, reflecting societal condemnation, and sending a clear deterrent message to would-be offenders.

3.3 Potential Impact of the Judgment

• Sentencing Benchmark: Confirms that Northern Irish courts may—and likely will—impose double-digit starting points for campaigns of grooming and sexual activity with minors, even where no breach of trust exists.
• Divergence from England & Wales: Creates a distinct and arguably tougher sentencing landscape, potentially influencing plea-bargaining strategy and forum considerations for cross-border offending.
• Guidance for Trial Judges: Encourages focus on totality and aggravating features rather than mechanical guideline ranges; invites consideration of consecutive sentences in egregious cases.
• Victim-Centric Rationale: Reinforces weight given to long-term psychological harm and humiliation associated with image-based abuse, likely shaping victim-impact jurisprudence.

4. Complex Concepts Simplified

• Determinate Custodial Sentence: A fixed term split into two halves—time served in prison followed by the remainder on licence (supervised release).
• Starting Point vs. Final Sentence: Judges identify a “starting point” after weighing aggravation/mitigation, then deduct credit for early guilty pleas to reach the final figure.
• Article 16/17 Offences: Provisions in the Sexual Offences (NI) Order 2008 criminalising sexual activity with a child and causing/inciting a child to engage in sexual acts.
• Totality Principle: Sentences for multiple offences must be proportionate to overall criminality—neither “crushing” nor “unduly lenient” when aggregated.
• Sexual Offences Prevention Order (SOPO): Civil order restricting future behaviour (e.g., contact with children, internet use) to protect the public.
• Category A/B/C Images: Classification of indecent images—A being the most severe (penetrative), C the least (erotic posing).

5. Conclusion

Costar v R cements the Northern Ireland Court of Appeal’s stance that robust, locally calibrated sentencing is warranted for prolonged, predatory sexual offending against children, with little deference to lower ranges found elsewhere. By endorsing a 12-year pre-plea starting point and emphasising the multitude of aggravating factors, the Court sends a clear message:

• Child-sexual offenders who engage in grooming, repeated penetrative acts, and image-based abuse can expect sentences close to statutory maxima even in the absence of classical breach-of-trust scenarios;
• The principle of totality allows high sentences while maintaining proportionality;
• England & Wales Guidelines offer useful reference but do not dictate Northern Irish outcomes.

Practitioners should therefore advise clients that early guilty pleas remain vital but may only mitigate—rather than avert—significant custodial exposure. More broadly, the judgment underscores the Northern Irish judiciary’s commitment to protecting children and reflecting societal condemnation through stern penal measures.
