R v AYP
[2024] EWCA Crim 952
The CPS is responsible for conducting prosecutions and has a significant margin of discretion in deciding whether to prosecute.
Prosecution of Offences Act 1985, s. 3(2)(a) and s. 10; Code for Crown Prosecutors
Judicial review of prosecutorial decisions is available only on conventional public law grounds (e.g., unlawful policy, failure to follow policy, irrationality, error of law).
R v DPP ex parte C [1995], L v DPP & Comm [2013], R (Monica) v DPP [2022], Campaign Against Antisemitism v DPP [2019]
The evidential test requires an objective assessment of whether there is a realistic prospect of conviction, considering the evidence and potential defences.
Code for Crown Prosecutors, section 4.6-4.8
Courts should apply a “self-denying ordinance” and only interfere with prosecutorial decisions sparingly, unless there's an unlawful policy, failure to follow policy, or a perverse decision.
R v DPP ex parte C [1995], L v DPP & Comm [2013], R (Monica) v DPP [2022]
The claim for judicial review was dismissed.
The court found no error of law or other justiciable failing in the CPS's decision. The CPS considered all relevant material, including the Claimant's credibility issues and the objective limb of self-defence, albeit not explicitly articulated in every review letter. The court deferred to the CPS's expertise and discretion in assessing the evidence and reaching a decision on whether a realistic prospect of conviction existed.
