Facts
- The case concerned the use of hearsay evidence—statements from individuals not present in court—in criminal proceedings.
- Al-Khawaja was convicted in the UK based mainly on hearsay evidence from a deceased witness.
- The European Court of Human Rights (ECtHR) was asked to consider whether reliance on such evidence breached Article 6 of the European Convention on Human Rights, which protects the right to a fair trial.
- The trial court had admitted hearsay evidence as primary or sole proof against the accused, raising concerns about the defendant’s ability to question witnesses.
- After the initial ECtHR ruling, the case was reviewed by the Grand Chamber.
Issues
- Whether the use of hearsay evidence as the sole or decisive basis for a conviction is compatible with Article 6 right to a fair trial.
- Whether adequate compensatory safeguards existed to mitigate disadvantages arising from the admission of hearsay evidence.
- How the overall fairness of the trial should be assessed in cases involving hearsay evidence, particularly when a key witness is unavailable.
Decision
- The ECtHR found that reliance on hearsay evidence as the main basis for conviction may breach Article 6 unless adequate safeguards are in place.
- In Al-Khawaja’s case, the Court found the compensatory measures taken during trial were insufficient.
- The Grand Chamber confirmed the "sole or decisive" rule but introduced flexibility, stating that overall fairness must be assessed in light of the entire proceedings.
- The judgment acknowledged that hearsay evidence can be admitted in some circumstances but stressed the need for robust safeguards to ensure fairness.
Legal Principles
- The "sole or decisive" rule: Conviction based exclusively or predominantly on hearsay evidence can undermine the fairness of the trial under Article 6 ECHR.
- Compensatory safeguards, such as additional evidence and opportunities to challenge credibility, are required to counterbalance any disadvantage caused by hearsay.
- The fairness of proceedings must be assessed as a whole, considering reasons for a witness's absence and the type of evidence admitted.
- National legal systems must ensure that their evidentiary rules comply with these principles.
Conclusion
The Al-Khawaja v United Kingdom judgment established the "sole or decisive" rule for hearsay evidence and obligated courts to provide effective safeguards, with overall trial fairness judged holistically under Article 6 ECHR.
