Exclusion of Sensitive Evidence: Insights from M, R. v ([2021] EWCA Crim 1934)

Introduction

M, R. v ([2021] EWCA Crim 1934) is a landmark case adjudicated by the England and Wales Court of Appeal (Criminal Division) on December 17, 2021. The case revolves around the application by the defendant, M, seeking to exclude evidence related to his sexual orientation from the trial proceedings. This evidence, the prosecution contends, is pivotal in establishing the context and motives behind the alleged controlling and coercive behavior towards his wife. The core legal dispute centers on the interpretation and application of Section 78 of the Police and Criminal Evidence Act 1984 (PACE) in conjunction with the European Convention on Human Rights (ECHR).

The parties involved include M, the defendant, his co-defendants (his father, mother, brother, and sister), and the complainant, M's wife. The key issues involve the admissibility of sensitive personal information under PACE, the balancing of fair trial rights, and the protective measures for individuals at risk of harm due to the disclosure of their sexual orientation.

Summary of the Judgment

The Court of Appeal reviewed the decision of the Crown Court, where Judge Edmunds QC had previously rejected M's application to exclude evidence of his sexual orientation. M argued that the disclosure of this information would adversely affect the fairness of the proceedings, invoking Section 78 of PACE and several articles of the ECHR. The Court upheld the Crown Court's decision, determining that the evidence was more than marginally relevant and that its admission did not adversely affect the fairness of the trial. Furthermore, the court concluded that Section 78 of PACE does not extend to protecting defendants from personal safety risks arising from the admission of admissible evidence.

Analysis

Precedents Cited

The judgment extensively references established case law to delineate the boundaries of Section 78 of PACE and its interaction with the ECHR. Key precedents include:

R v Sang [1980] AC 402: Limited the common law's discretion to exclude improperly obtained evidence.
R v Looseley and Attorney General's Reference (No.3 of 2000) [2001] UKHL 53: Clarified the scope of Section 78 in the context of abuse of process.
Ex p Bennett [1994] 1 AC 42: Affirmed the court's jurisdiction to stay proceedings in cases of serious abuse of power by the executive.
R v Smurthwaite [1994] 1 All ER 898: Highlighted that entrapment does not itself provide a defense but may warrant exclusion of evidence.
R v Horseferry Road Magistrate's Court, Ex p Bennett [1994] 1 AC 42: Emphasized the judiciary's role in preventing abuse of the court's process.

These cases collectively establish that while Section 78 provides a mechanism to exclude evidence that may render proceedings unfair, its application is narrowly confined to procedural fairness rather than broader personal safety concerns.

Legal Reasoning

The court's legal reasoning focused on interpreting the scope of Section 78 of PACE, which permits the exclusion of evidence if its admission would adversely affect the fairness of the proceedings. The key points include:

Relevance of Sexual Orientation Evidence: The court found that the evidence of M's sexual orientation was more than marginally relevant as it provided context to the abuse allegations.
Section 78 Limitations: The court clarified that Section 78 pertains solely to the fairness of the trial process, not to protect individuals from personal safety risks.
Data Protection Considerations: While acknowledging potential breaches of the Data Protection Act 2018 (DPA), the court concluded these did not materially influence the decision to admit the evidence under Section 78.
Responsibility of Authorities: The court emphasized that safeguarding the defendant's safety is the responsibility of prosecuting authorities, not the courts under Section 78.

The court thus concluded that the exclusion of evidence on the grounds presented by M was not supported by the statutory framework or established jurisprudence.

Impact

This judgment reaffirms the narrow interpretation of Section 78 of PACE, limiting its application to procedural fairness within the trial. It underscores that protective measures for defendants facing personal safety risks due to sensitive evidence disclosures remain the responsibility of prosecuting authorities and not the judiciary through Section 78. The decision clarifies that the court does not possess inherent powers to exclude evidence for reasons beyond the fairness of the trial itself, thereby setting a clear boundary for future cases involving sensitive personal information.

Furthermore, the ruling emphasizes the importance of adhering to data protection laws and the procedural safeguards in the handling of sensitive information, without conflating these with the grounds for excluding evidence under Section 78.

Complex Concepts Simplified

Section 78 of PACE

Section 78 of the Police and Criminal Evidence Act 1984 allows a court to exclude evidence if its admission would undermine the fairness of the trial. This provision is intended to ensure that trials are conducted on a just and equitable basis, preventing the introduction of evidence that could prejudice the outcome.

European Convention on Human Rights (ECHR)

The ECHR is an international treaty to protect human rights and fundamental freedoms in Europe. Articles cited in this case include:

Article 2: Right to life.
Article 3: Prohibition of torture and inhuman or degrading treatment.
Article 6: Right to a fair trial.
Article 8: Right to respect for private and family life.

Preparation for a Pre-Trial Hearing

A preparatory hearing is a preliminary session where complex or sensitive issues are addressed before the main trial. In this case, the preparatory hearing was necessary to determine whether evidence related to M's sexual orientation should be excluded.

Conclusion

The judgment in M, R. v serves as a pivotal reference point in understanding the boundaries of evidence admissibility under Section 78 of PACE. It underscores the principle that while courts have mechanisms to ensure procedural fairness, the protection of defendants from personal safety risks associated with sensitive evidence remains outside the judicial purview and within the responsibilities of prosecuting authorities. This decision reinforces the judiciary's role in maintaining the integrity of the trial process without overstepping into areas designated for law enforcement and prosecutorial duties.

Moreover, the case highlights the importance of clear legislative interpretations and the necessity for authorities to implement appropriate safeguards when handling sensitive information, ensuring that the rights of all parties are respected within the legal framework.
