Interpretation of Section 64(3B) of PACE in AG Reference No. 3 of 1999: Admissibility of Evidence from Prohibited DNA Investigations
Introduction
The case of Attorney General's Reference No. 3 of 1999 ([2000] UKHL 63) represents a pivotal moment in the interpretation of the Police and Criminal Evidence Act 1984 (PACE), particularly concerning the admissibility of DNA evidence obtained following procedural breaches. This commentary delves into the background of the case, the legal questions presented, the House of Lords’ judgment, and its implications for future legal proceedings.
Summary of the Judgment
In this case, the defendant was initially arrested for burglary and provided a saliva sample under section 63(3A) of PACE. After being acquitted, the sample should have been destroyed per section 64(1). However, the DNA from this sample was retained and later matched to DNA evidence from a subsequent rape case, leading to a new arrest. The Court of Appeal held that using this DNA breached section 64(3B) of PACE, rendering the evidence inadmissible. The House of Lords overturned this decision, clarifying the interpretation of section 64(3B) and establishing that while the breach occurred, the resulting evidence must be evaluated under the discretion provided by section 78 of PACE rather than being automatically inadmissible.
Analysis
Precedents Cited
The judgment extensively referenced prior cases to elucidate the legal framework surrounding evidence admissibility. Notable among them are:
- London and Clydeside Estates Ltd. v. Aberdeen District Council [1980] 1 WLR 182: Highlighted the dangers of rigidly classifying legal provisions as either mandatory or directory, advocating for a nuanced approach based on consequences rather than form.
- R. v. Khan (Sultan) [1997] AC 558: Reinforced the principle that the admissibility of evidence should consider its impact on the fairness of the trial, aligning with human rights considerations.
- Reg. v. Weir (unreported, 26 May 2000): Demonstrated the Court of Appeal's initial stance, which the House of Lords found flawed.
- Kuruma v. The Queen [1955] AC 197: Established that relevant evidence is admissible regardless of how it was obtained, barring specific statutory or discretionary exclusions.
These precedents collectively influenced the Lords' approach, emphasizing a balance between statutory interpretation and the overarching principles of fairness and justice.
Legal Reasoning
The Lords dissected section 64(3B) of PACE, which addresses the use of DNA samples that should have been destroyed following an acquittal. Subsection (3B)(a) explicitly prohibits using such samples in evidence against the individual. In contrast, subsection (3B)(b) prohibits using the information for investigating other offenses without explicit statutory mandates. The House of Lords clarified that (3B)(b) does not inherently render the evidence inadmissible but instead subjects it to the trial judge's discretion under section 78 of PACE.
This interpretation ensures that evidence obtained from a prohibited investigation is not automatically excluded but is evaluated based on its fairness and the circumstances of its acquisition. The Lords emphasized that statutory language should guide the interpretation, reserving discretionary exclusion of evidence to situations where its admission would undermine the fairness of the judicial process.
Impact
The judgment has profound implications for criminal law and evidentiary procedures:
- Balancing Act: It reaffirms the judiciary's role in balancing the state's interest in prosecuting crimes with the protection of individual rights.
- Judicial Discretion: Enhances the importance of judicial discretion in determining the admissibility of evidence, ensuring that rigid statutory interpretations do not impede justice.
- Future Cases: Sets a precedent for how similar cases involving DNA evidence and procedural breaches will be handled, promoting a more flexible and fairness-oriented approach.
Complex Concepts Simplified
Section 64(3B) of PACE
This section deals with the handling of DNA samples obtained during criminal investigations. Specifically:
- Subsection (3B)(a): Prohibits using the DNA sample in evidence against the individual from whom it was taken if they were acquitted of the initial offense.
- Subsection (3B)(b): Prevents using information from the DNA sample for investigating other offenses, but does not automatically exclude such evidence from trials.
Section 78 of PACE
Grants the trial judge the discretion to exclude evidence if its admission would negatively impact the fairness of the trial. This includes considering how the evidence was obtained.
Conclusion
The House of Lords, in AG Reference No. 3 of 1999, clarified the interpretation of section 64(3B) of PACE, emphasizing that evidence derived from DNA samples that should have been destroyed following an acquittal is not automatically inadmissible. Instead, such evidence is subject to judicial discretion under section 78 of PACE, ensuring that each case is assessed on its individual merits and the fairness of proceedings is maintained. This judgment strikes a crucial balance between safeguarding individual rights and empowering the state to effectively prosecute serious crimes, thereby reinforcing the integrity and fairness of the legal system.
Moving forward, legal practitioners must carefully navigate the provisions of PACE, understanding that while statutory language sets the framework, judicial discretion plays a pivotal role in the application of the law to ensure justice is both served and perceived to be served.
