R v AYP
[2024] EWCA Crim 952
Judicial review of prosecutorial decisions is a highly exceptional remedy, granted only in extremely rare circumstances.
Sharma v Brown-Antoine [2006] UKPC 57
Leave for judicial review should not be granted if a suitable alternative remedy exists.
Judicial Review Act Chapter 7:08, section 9
The DPP has a wide discretion in deciding whether to prosecute or continue a prosecution, and this discretion is subject to judicial review only in exceptional circumstances, such as bad faith or an abuse of process.
Matalulu v DPP [2003] 4 LRC 712; Mohit v Director of Public Prosecutions [2006] UKPC 20
A prosecutor must act lawfully and direct himself correctly in law.
R (Corner House Research) v Director of the Serious Fraud Office [2008] UKHL 60
Abuse of process in criminal proceedings can occur when a fair trial is impossible or when the trial would offend the court's sense of justice and propriety.
R v Maxwell [2010] UKSC 48; Warren v Attorney General for Jersey [2011] UKPC 10
The Privy Council allowed the appeal.
The Respondents had an adequate alternative remedy available within the criminal proceedings. The lower courts erred in finding irrationality and abuse of process; the DPP's decision to continue the prosecution, given conflicting statements from the key witness, was not exceptionally unreasonable or an abuse of process.
