McCartney & Anor, R. v

Factual and Procedural Background

The convictions of Plaintiff A and Plaintiff B in 1979 for murder and related offences were referred to the Court of Appeal by the Criminal Cases Review Commission under statutory provisions governing appeals in Northern Ireland. Plaintiff A was convicted of two murders and membership of a proscribed organisation, receiving life sentences with a 25-year minimum term. Plaintiff B was convicted of murder, conspiracy, attempted murder, possession of a firearm, and membership of a proscribed organisation, with determinate sentences concurrent with a life term. Both plaintiffs had their initial appeals dismissed in 1982. In 2002, their solicitors applied to the Commission, which led to the referral of their convictions to the Court of Appeal for reconsideration.

The facts surrounding the murders involved the killing of a police officer and a prominent industrialist in The City in early 1977. Plaintiff A was arrested shortly after the second murder, with forensic evidence linking firearms and vehicles to the crimes. Both plaintiffs were interviewed multiple times during their detention, with the prosecution relying heavily on statements of admission made during these interviews. Allegations of ill-treatment and assault during detention and interviews were made by both plaintiffs and other detainees held contemporaneously. Fresh evidence, including internal memoranda from the Public Prosecution Service and medical reports, was introduced during the appeal process.

Legal Issues Presented

1. Whether the convictions of Plaintiff A and Plaintiff B are unsafe in light of fresh evidence concerning the conduct of police officers during detention and interviews.
2. The admissibility and reliability of statements of admission obtained during police interviews allegedly involving ill-treatment.
3. The impact of undisclosed internal memoranda and prior prosecutions against interviewing officers on the credibility of the prosecution case.
4. The application of legal principles governing appeals based on fresh evidence and the assessment of the safety of convictions.

Arguments of the Parties

Arguments on behalf of Plaintiff A

• The conditions of detention were oppressive, including prolonged interviews without breaks and denial of access to legal counsel, contrary to prevailing rules.
• Ill-treatment began early during interviews, involving physical assaults by specific police officers, undermining the voluntariness and reliability of confession statements.
• Fresh evidence, including internal memoranda and related cases of police misconduct, could have influenced the trial judge’s assessment of police credibility and the admissibility of evidence.
• Evidence from contemporaneous detainees alleging ill-treatment supports claims of misconduct during Plaintiff A’s detention.

Arguments on behalf of Plaintiff B

• Plaintiff B alleged physical and psychological abuse during interviews, including threats and assaults by police officers.
• Statements of confession were dictated under duress and may not reflect Plaintiff B’s true admissions.
• Medical evidence and fresh material suggest a prima facie case of ill-treatment, shifting the burden to the prosecution to prove absence of misconduct.
• Similarity between Plaintiff B’s allegations and those of other detainees, including the involvement of the same interviewing officers, undermines the prosecution’s case.

Arguments on behalf of the Crown

• There was insufficient nexus between new evidence relating to other detainees and the cases of Plaintiff A and Plaintiff B to affect the safety of their convictions.
• Recommendations for prosecution of officers were not accepted and prior failed prosecutions diminish the impact of related allegations.
• The new evidence raises questions but does not establish that the convictions are unsafe.

Precedent	Rule or Principle Cited For	Application by the Court
Stafford v Director of Public Prosecutions [1974] AC 315	Guidance on assessing whether fresh evidence renders a verdict unsafe; court’s discretion in evaluating impact on jury verdict.	The court applied the principle that it is not mandatory to determine what a jury would have done, only whether the conviction is unsafe.
R v Pendleton [2002] 1 WLR 72	Clarification of the test for safety of conviction when fresh evidence is introduced; focus on risk assessment rather than guilt.	The court used this framework to assess the fresh evidence and its potential effect on the safety of the convictions.
R v King [2000] 2 Cr.App.R 39	Consideration of denial of rights and safeguards at the time of trial in determining safety of conviction.	The court referenced this precedent in relation to access to legal counsel and other procedural safeguards.
R v Seymour Williams and Patrick Smith [1995] 1 Cr.App.R. 74	Admissibility of evidence discrediting police officers in subsequent cases affecting safety of prior convictions.	The court acknowledged this precedent to support consideration of discrediting evidence arising after the original trial.
R v Twitchell [2000] Crim.L.R. 468	Principles for cross-examination of police officers about prior misconduct and its relevance to credibility assessments.	The court noted the potential for cross-examination of officers based on acquittals indicating disbelief of their evidence.

Court's Reasoning and Analysis

The Court carefully examined the fresh evidence, including memoranda from the Public Prosecution Service and medical reports, which indicated that one of the interviewing officers faced allegations of assault in other cases contemporaneous with the plaintiffs’ interviews. The court noted that the prosecution’s case rested heavily on statements of admission obtained during interviews conducted by the same team of officers. The evidence of ill-treatment by other detainees, and the failure to disclose internal memoranda relating to possible police misconduct, raised questions about the reliability of the officers’ testimony and the voluntariness of the confessions.

The court applied established legal principles from leading authorities governing appeals based on fresh evidence, focusing on whether the convictions were safe rather than on the guilt or innocence of the plaintiffs. It acknowledged the trial judge’s original findings but emphasized that had the judge been aware of the fresh evidence, particularly the prima facie case of assault against an interviewing officer, he might have reached different conclusions about the credibility of the police evidence and the admissibility of confession statements.

Despite some reservations about the credibility of witnesses who alleged ill-treatment, the court found that the cumulative effect of the new material created a distinct feeling of unease about the safety of the convictions, especially as they depended largely on admissions made during interviews by officers whose conduct was now in question.

Holding and Implications

The Court quashed the convictions of both Plaintiff A and Plaintiff B.

This decision directly overturns the prior convictions on grounds of safety, grounded in the fresh evidence undermining the reliability of key prosecution evidence. The ruling does not establish new legal precedent but reinforces the importance of full disclosure and the assessment of police conduct in determining the safety of convictions based on confession evidence. The outcome underscores the court’s duty to prevent miscarriages of justice where fresh evidence raises significant doubt about the integrity of the original trial process.
