In criminal law an abuse of process occurs when the criminal justice system is misused in a way that undermines fairness, justice or the integrity of legal proceedings.
It involves actions that exploit the judicial process for improper purposes, such as harassing a defendant, causing unjust delays, or pursuing a case without legitimate grounds.
The concept is enshrined in the court’s inherent jurisdiction to protect its processes, as guided by the Criminal Procedure Rules 2020(CrimPR) and established case law.
Defining Abuse of Process
An abuse of process arises when the prosecution’s conduct or case circumstances render a fair trial impossible or unjust.
CPR Rule 3.28, part of the case management framework, empowers courts to give directions to ensure proceedings are conducted efficiently and fairly, which includes identifying and addressing potential abuses of process.
This rule supports the overriding objective in CPR 1.1 to deal with cases justly, ensuring fairness, efficiency, and compliance with the European Convention on Human Rights and Human Rights Act 1998, particularly Article 6 (right to a fair trial). Examples of abuse of process include:
- Improper Motives: Prosecuting to harass or intimidate rather than seek justice.
- Unreasonable Delay: Excessive delays that prejudice the defendant’s defence, such as faded memories or lost evidence.
- Non-Disclosure: Failing to disclose exculpatory evidence, breaching the Criminal Procedure and Investigations Act 1996.
- Entrapment: Inducing a defendant to commit a crime they would not otherwise have committed.
- Bad Faith Prosecutions: Pursuing a case without sufficient evidence or for ulterior motives, like political pressure.
Legal Framework
The Criminal Procedure Rules 2020 (CrimPR) are a comprehensive set of rules governing the practice and procedure of criminal courts in England and Wales. They provide a framework to ensure criminal cases are managed justly, efficiently, and fairly, as mandated by the Courts Act 2003, which empowers the Criminal Procedure Rule Committee to make these rules.
CrimPR 1.1, the overriding objective, requires courts to manage cases to avoid unfairness, inefficiency, or prejudice. Unlike specific statutory provisions in other contexts, criminal abuse of process relies on judicial discretion and precedent.
1.1.—(1) The overriding objective of this procedural code is that criminal cases be dealt with justly.
(2) Dealing with a criminal case justly includes―
(a) acquitting the innocent and convicting the guilty;
(b) treating all participants with politeness and respect;
(c) dealing with the prosecution and the defence fairly;
(d) recognising the rights of a defendant, particularly those under Article 6 of the European Convention on Human Rights;
(e) respecting the interests of witnesses, victims and jurors and keeping them informed of the progress of the case;
(f) dealing with the case efficiently and expeditiously;
(g) ensuring that appropriate information is available to the court when bail and sentence are considered; and
(h) dealing with the case in ways that take into account―
(i) the gravity of the offence alleged,
(ii) the complexity of what is in issue,
(iii) the severity of the consequences for the defendant and others affected, and
(iv) the needs of other cases.
The Criminal Procedure Rules 2020 – 1.1 The Overriding Objective
CrimPR 1.2 outlines the duty of all participants in a criminal case to actively assist the court in achieving the overriding objective.
1.2.—(1) Each participant, in the conduct of each case, must―
(a) prepare and conduct the case in accordance with the overriding objective;
(b) comply with these Rules, practice directions and directions made by the court; and
(c) at once inform the court and all parties of any significant failure (whether or not that participant is responsible for that failure) to take any procedural step required by these Rules, any practice direction or any direction of the court. A failure is significant if it might hinder the court in furthering the overriding objective.
(2) Anyone involved in any way with a criminal case is a participant in its conduct for the purposes of this rule.
The Criminal Procedure Rules 2020 – 1.2 The duty of the participants in a criminal case
CrimPR 3.28 allows courts to give directions for the effective management of criminal cases, which includes addressing abuses of process. While the rule itself focuses on case progression, it enables judges to scrutinise proceedings for potential misuse, ensuring they align with the overriding objective of fairness.
3.28.—(1) This rule applies where a defendant wants the Crown Court to stay the case on the grounds that the proceedings are an abuse of the court, or otherwise unfair.
(2) Such a defendant must—
(a) apply in writing—
(i) as soon as practicable after becoming aware of the grounds for doing so,
(ii) at a pre-trial hearing, unless the grounds for the application do not arise until trial, and
(iii) in any event, before the defendant pleads guilty or the jury (if there is one) retires to consider its verdict at trial;
(b) serve the application on—
(i) the court officer, and
(ii) each other party; and
(c) in the application—
(i) explain the grounds on which it is made,
(ii) include, attach or identify all supporting material,
(iii) specify relevant events, dates and propositions of law, and
(iv) identify any witness the applicant wants to call to give evidence in person.
(3) A party who wants to make representations in response to the application must serve the representations on—
(a) the court officer; and
(b) each other party,
not more than 10 business days after service of the application.
The Criminal Procedure Rules 2020 – 3.28 Application to stay case for abuse of process
The landmark case R v Horseferry Road Magistrates’ Court, ex parte Bennett [1994] 1 AC 42 established that courts can stay or dismiss proceedings deemed abusive. Rule 3.28 supports this by providing a mechanism for courts to intervene when proceedings risk unfairness or oppression.
Unlike specific statutory provisions in other contexts, criminal abuse of process relies on judicial discretion, with Rule 3.28 facilitating proactive case management to prevent or remedy abuses. Courts assess whether continuing a case would undermine public confidence or violate defendants’ rights.
Judicial Response
Courts have broad powers to address abuse of process, including:
- Staying Proceedings: Halting a case if a fair trial is impossible or unjust, as supported by CrimPR Rule 3.28 directions.
- Dismissing Charges: Dropping charges due to prosecutorial misconduct.
- Excluding Evidence: Suppressing improperly obtained evidence under Section 78 of the Police and Criminal Evidence Act 1984.
For instance, in R v Beckford [1996] 1 Cr App R 94, non-disclosure of evidence was deemed an abuse, prompting judicial intervention. Similarly, R v Maxwell [2010] UKSC 48 clarified that remedies depend on the abuse’s severity and impact on fairness.
Importance of Preventing Abuse of Process
Preventing abuse of process, as facilitated by CrimPR Rule 3.28, is vital to maintaining public trust in the criminal justice system. It protects defendants from oppressive treatment, ensures efficient use of court resources, and upholds the integrity of proceedings.
