The Judiciary of Northern Ireland has published a compendium of sentencing policy statements drawn from guideline judgments, covering 18 categories of offence and providing a consolidated reference point for sentencers across the jurisdiction. The document was produced at the request of the Lord Chief Justice's Sentencing Group, which identified a need to extract and centralise key sentencing principles during a review of the Judicial Studies Board Sentencing Guideline Compendium.

On murder sentencing, the Court of Appeal in R v John Paul Whitla [2024] NICA 65 recalibrated the long-standing McCandless framework. The court confirmed that 15 to 16 years is now the normal starting point for murder, reflecting high culpability. A reduced starting point of 12 years applies only in exceptional cases of low culpability, while cases of exceptionally high culpability attract a starting point of 20 years or more. The court noted that multiple stabbing cases can fall within the highest bracket. In R v Stephen McKinney [2024] NICA 35, the court confirmed that coercive and controlling behaviour in a relationship is a specific aggravating factor in domestic murders, with the court stating that sentences of 20 years and possibly more will be upheld in such cases.

For online blackmail and so-called sextortion offences, R v Jonathan Playfair [2024] NICA 21 confirmed that deterrent custodial sentences should be imposed in all but exceptional cases, particularly where victims are young or vulnerable. The court noted a significant increase in blackmail cases before the Crown Court in Northern Ireland involving online or social media platforms, and endorsed the trial judge's observation that sextortion has expanded from known-party social media offending to organised online operations where victims have in some cases taken their own lives after being threatened with humiliation.

In the area of drug offences, the compendium restates that supply of controlled drugs will attract an immediate custodial sentence in all but exceptional cases, drawing on R v McKeown and Han Lin [2013] NICA 28 and a line of authority stretching back to R v Hogg [1994]. For cannabis cultivation on a network scale, R v Luong Bui [2022] NICA 78 established a sentencing bracket of between 7 and 14 years for those controlling multiple operations, above the 6 to 7 year starting point applicable to organisers of a single cannabis factory. The court also confirmed that an offender's addiction carries no mitigating weight in drugs supply cases.

On manslaughter, R v Barry Donnelly [2025] NICA 7 provided new guidance for diminished responsibility cases, approving a stepped methodology for assessing residual culpability and setting guideline tariff ranges: 6 to 8 years for low culpability, 8 to 10 years for medium culpability, and 10 to 12 years for high culpability. The court also stated that judges should, in every such case, explain to the public in plain terms the nature of the mental illness involved, the level of residual culpability, and the role of the Parole Commissioners in any future release decision.

For terrorist offences, the compendium draws together a body of authority confirming that deterrence is the dominant sentencing consideration, that personal mitigation carries minimal weight, and that offences with a paramilitary dimension should attract more severe sentences than equivalent non-terrorist offending. R v Fionnghuale Perry [2024] NICA 11 noted that sentencing reforms introduced in 2021 reflected Parliament's intention to impose a more austere regime for terrorist offenders, with a particular focus on public protection.

The compendium also addresses domestic violence, environmental offences, robbery, sexual offences against children, road traffic matters, and discretionary life sentences. Throughout, the Court of Appeal has consistently cautioned against a mechanistic application of England and Wales Sentencing Council guidelines, stating that Northern Ireland courts should draw on aggravating and mitigating factors identified in those guidelines without being constrained by the sentencing brackets they prescribe. In R v King v Darryl Haughey [2025] NICA 10, the court addressed non-fatal strangulation, confirming that the statutory domestic abuse aggravator should be reflected as a clearly identified and labelled portion of the overall sentence to deter violent behaviour in domestic settings.

The document is intended as a practical reference for sentencers in Northern Ireland and does not alter existing law. Its publication follows a decision by the Lord Chief Justice's Sentencing Group that consolidating key policy statements in a single accessible format would assist the judiciary.
