Factual and Procedural Background
This opinion concerns an appeal brought by the Secretary of State for Foreign and Commonwealth Affairs ("the Foreign Secretary") against a decision of the Divisional Court to include seven short subparagraphs ("the redacted paragraphs") in the open version of a judgment ("the first judgment"), despite the Foreign Secretary's assertion through multiple Public Interest Immunity Certificates ("certificates") that publication would pose a real risk of serious harm to UK national security.
The litigation arose from proceedings initiated on 6 May 2008 by a detainee ("Mr Mohamed"), formerly resident in the United Kingdom and detained at Guantanamo Bay, seeking disclosure of documents held by UK authorities relevant to his claim that confessions he made to US interrogators were obtained under torture or cruel, inhuman or degrading treatment. The claim for disclosure was based on the Norwich Pharmacal principle, requiring third parties involved in wrongdoing to provide information to the victim to identify and pursue wrongdoers.
The Divisional Court delivered a series of judgments between 2008 and 2009, addressing issues of principle, disclosure, public interest immunity, and national security. The core dispute focused on whether the seven redacted paragraphs, summarizing reports from the US intelligence services to UK intelligence about Mr Mohamed's detention and treatment, should be published in the open judgment. The Foreign Secretary contended that publication would breach the "control principle"—an understanding that intelligence shared between allied states remains confidential to the providing state—and would risk damaging intelligence-sharing arrangements vital to national security.
Following extensive hearings, the Divisional Court initially ordered the redacted paragraphs to remain excluded from the open judgment, balancing national security concerns against open justice. Subsequently, after further developments including the election of President Obama, the release of US Department of Justice memoranda on interrogation techniques, and a detailed US District Court judgment validating Mr Mohamed's torture claims, the Divisional Court reversed its position, ordering publication of the redacted paragraphs. The Foreign Secretary appealed this decision.
Legal Issues Presented
- Whether the seven redacted paragraphs should be included in the open version of the first judgment, balancing the public interest in open justice against national security concerns.
- The application and scope of the "control principle" in intelligence sharing between the UK and the US, particularly whether it constitutes an absolute principle preventing disclosure of intelligence-derived information without the provider state's consent.
- The extent of judicial deference owed to the executive's assessment of national security risks in public interest immunity claims.
- The impact of a US District Court judgment finding that the detainee's torture claims were true on the UK court's assessment of confidentiality and national security risks.
- The proper approach to public interest immunity regarding material derived from foreign intelligence sources when such information has become publicly available through foreign judicial proceedings.
Arguments of the Parties
Appellant's Arguments
- The redacted paragraphs are a summary of intelligence material provided under confidential intelligence-sharing arrangements and publication breaches the control principle.
- The Divisional Court erred in concluding that the redacted paragraphs were not intelligence material and wrongly substituted its own view for the Foreign Secretary's assessment of the risk to national security.
- The Foreign Secretary's certificates, supported by evidence including a CIA letter and notes of meetings with the US Secretary of State, established a real risk of serious harm to UK national security if the paragraphs were published.
- The control principle is fundamental to intelligence sharing and its breach would result in a review and likely reduction of intelligence sharing by the US and other allied countries.
- The Divisional Court wrongly dismissed the Foreign Secretary's good faith and rational judgment on national security grounds.
- The US District Court judgment finding torture claims true does not alter the sensitivity of the intelligence-derived material or the control principle.
- The decision to publish was gratuitous and unnecessary given that the original proceedings had become academic following Mr Mohamed's release and dropping of charges in the US.
Respondent's Arguments
- The redacted paragraphs are integral and necessary parts of the court's reasoning and must be published to ensure open justice and public accountability.
- Mr Mohamed is entitled to know the full reasons for the judgment, especially given the serious allegations of UK involvement or facilitation in torture and ill-treatment.
- The control principle is not absolute and can be overridden by courts when the public interest in disclosure outweighs confidentiality.
- The US District Court judgment publicly confirmed the truth of Mr Mohamed's torture claims, undermining the basis for confidentiality and national security concerns.
- The information in the redacted paragraphs is already largely in the public domain or can be inferred from open judgments.
- The principle of open justice and the rule of law require publication, particularly where serious wrongdoing by state actors is alleged.
- The Foreign Secretary's continued resistance to publication is inconsistent with the evidence and the public interest.

Court's Reasoning and Analysis
The court began by acknowledging the gravity of the terrorism threat and the critical importance of intelligence sharing between the UK and the US, grounded in the "control principle" that intelligence material shared remains confidential to the providing state. The Foreign Secretary's repeated Public Interest Immunity Certificates asserted that publication of the redacted paragraphs would breach this principle and risk severe damage to national security through the potential constriction of intelligence sharing.
The court recognized the fundamental constitutional role of the executive in assessing national security risks and generally deferred to the Foreign Secretary's judgment, given his superior access to intelligence and expertise. However, the court retained ultimate authority to determine whether publication was justified, applying established public interest immunity principles and balancing the competing interests of national security and open justice.
Initially, the Divisional Court accepted the Foreign Secretary's position and ordered the redaction of the paragraphs. Subsequent developments, including a US District Court judgment publicly confirming the truth of Mr Mohamed's torture allegations, shifted the factual landscape. The court found that the information contained in the redacted paragraphs was no longer secret or intelligence material, as it had been publicly disclosed by a US court in proceedings involving the US Government.
The court analyzed the Foreign Secretary's continued reliance on the control principle after this disclosure and concluded that the principle, as applied here, lacked factual content and could not justify continued suppression. The court emphasized the importance of open justice, democratic accountability, and the rule of law, particularly in cases involving serious allegations of state wrongdoing such as torture.
The court also found that the redacted paragraphs were integral to the reasoning of the first judgment and that non-disclosure would result in unfairness to Mr Mohamed, who would be deprived of knowing the full reasons for the court's conclusions, while the intelligence services implicated would have full access.
Balancing the public interest in open justice against national security, the court concluded that the risk to national security was speculative and diminished by the public availability of the material. The court rejected the Foreign Secretary's appeal, holding that the redacted paragraphs should be published.
Holding and Implications
DISMISSED
The court dismissed the appeal by the Foreign Secretary, ordering that the seven redacted paragraphs be included in the open version of the first judgment. This decision affirms the principle that the judiciary has ultimate authority over the publication of its reasons and that public interest immunity claims must be carefully scrutinized and balanced against the fundamental constitutional principles of open justice, freedom of expression, and democratic accountability.
The ruling emphasizes that the control principle in intelligence sharing, while important, is not absolute and cannot justify suppression of judicial findings once the material has become publicly available through foreign judicial processes. The decision ensures that litigants, even in sensitive national security cases, are entitled to know the full reasons for judgments affecting their rights and that the public is entitled to transparency regarding serious allegations of government misconduct.
No new precedent was established beyond the application of existing public interest immunity and open justice principles in the context of intelligence sharing and national security.
