Background
Passengers and crew of British Airways flight BA149 brought claims arising from their detention and mistreatment by Iraqi troops following Iraq's invasion of Kuwait on 1–2 August 1990. They allege that the Cabinet Office, Foreign, Commonwealth and Development Office, and Ministry of Defence failed adequately—or at all—to act on warnings of a likely invasion and to advise British Airways to divert the flight from Kuwait.
The claimants also allege that the government intentionally used BA149 to deploy a military or quasi-military team known as “the Increment.” After searching for relevant material, the three government defendants sought permission to withhold certain documents on public interest immunity grounds. The claimants and British Airways urged the court to test the claim rigorously, particularly regarding material bearing on whether UK Special Forces were aboard the aircraft.
The Court’s Holding
Mr Justice Garnham allowed the public interest immunity application. After open submissions and a closed examination of the disputed documents and government submissions, he held—subject to minor points to be reflected in the final disclosure—that the public interest in withholding the material outweighed the interest in disclosure for the fair administration of justice.
The court found that Ministry of Defence gists substantially mitigated the withholding of documents not disclosed in full. For material that could not be gisted, no measure short of non-disclosure would adequately protect the public interest. The government was also justified in neither confirming nor denying UK Special Forces' involvement because the utility of that response depends on maintaining it except in the most unusual circumstances.
Key Takeaways
- A public interest immunity claim requires the court to balance the risk of serious harm from disclosure against the public interest in disclosure for the administration of justice.
- Gisting may mitigate non-disclosure, but the court may permit complete withholding where no lesser measure can adequately protect the public interest.
- The court upheld the government's refusal either to confirm or deny whether UK Special Forces were aboard BA149.
Why It Matters
The ruling permits the government defendants to withhold sensitive evidence in litigation concerning the treatment of BA149's passengers and crew during Iraq's invasion of Kuwait. It does not determine the merits of the underlying negligence and alleged deployment claims.
The judgment illustrates the High Court's independent role in scrutinizing public interest immunity claims, including through closed examination of the documents, while considering whether partial disclosure or gists can protect both national interests and fairness in the proceedings.
