Beatty v Director of Public Prosecutions & Anor

Factual and Procedural Background

The appellant sought judicial review to compel the Director of Public Prosecutions (DPP) to direct the Chief Constable of the Police Service to accelerate investigation into the death of her brother, which occurred in a series of incidents in February 1973 in Northern Ireland. The death was originally subject to an inquest in 1975 resulting in an open verdict, with a new inquest scheduled. The appellant’s solicitors requested the Attorney General for Northern Ireland (AGNI) in 2017 to direct a fresh inquest, which was refused in 2018. The AGNI referred the matter to the DPP under section 35(5)(a) of the Justice (Northern Ireland) Act 2002, empowering the DPP to request investigation by the Police Service.

Between 2018 and 2020, the DPP communicated with the Police Service and Ministry of Defence regarding the case, but ultimately decided not to exercise the power under section 35(5)(a) to compel further investigation. The appellant initiated proceedings in 2020 challenging this decision. The High Court refused leave for judicial review against the DPP, and while leave was granted against the Police Service, the appellant discontinued that claim following a Supreme Court decision. The appeal to the Court of Appeal concerns the proper construction of section 35(5)(a) and the lawfulness of the DPP’s decision not to direct prioritisation of the investigation.

Legal Issues Presented

1. What is the correct construction of section 35(5)(a) of the Justice (Northern Ireland) Act 2002 concerning the DPP’s power to request information or investigation from the Chief Constable?
2. Does section 35(5)(a) empower the DPP to direct the Chief Constable to prioritise a particular police investigation?
3. Was the DPP’s decision not to exercise the power under section 35(5)(a) in this case lawful and reasonable?

Court's Reasoning and Analysis

The court undertook a detailed statutory interpretation of section 35(5)(a) of the Justice (Northern Ireland) Act 2002, situating it within the broader statutory framework governing the roles of the DPP and the Chief Constable/Police Service. The Justice Act established a clear division of responsibilities: the Police Service has the duty to investigate offences, while the DPP holds exclusive prosecutorial functions.

Section 35(5)(a) obliges the Chief Constable to provide information to the DPP upon request regarding matters appearing to need investigation for possible offences. The court concluded this provision contemplates three main scenarios: (1) the Chief Constable is unaware of a possible offence requiring investigation; (2) the Chief Constable has consciously decided not to investigate a matter the DPP believes merits investigation; and (3) the DPP directs further specified investigations after receiving police files.

The court reasoned that while the DPP may have a limited power to direct investigations, this power is not broad enough to include directing the Police Service to prioritise particular investigations within their overall caseload. The Police Service retains autonomy over operational decisions, including resource allocation and investigation sequencing, as affirmed by the principle in Hill v Chief Constable of West Yorkshire. Judicial review of police decisions is limited to instances of unreasonableness.

Applying these principles, the court found that the DPP’s decision not to exercise the power under section 35(5)(a) to compel prioritisation was lawful, reasonable, and consistent with the statutory framework. The appellant failed to show any exceptional circumstance warranting a different approach. The court also noted that the DPP’s narrower construction of the provision, while more restrictive than the court’s own interpretation, was not legally erroneous.

Holding and Implications

The appeal is dismissed.

The court upheld the High Court’s refusal to grant judicial review against the DPP’s decision not to direct prioritisation of the police investigation under section 35(5)(a). This decision confirms the limited scope of the DPP’s power to compel investigations and reinforces the Police Service’s operational independence in managing legacy case workloads. No new precedent altering the balance of prosecutorial and investigatory powers was established; the ruling clarifies statutory interpretation but leaves existing police discretion intact. The direct effect is that the appellant’s challenge fails and the status quo regarding investigation prioritisation remains unchanged.
