House of Lords Decision on Fair-Trial Requirements in Control-Order Proceedings

Factual and Procedural Background

Three individuals (“Appellant 1”, “Appellant 2” and “Appellant 3”) were made subject to non-derogating control orders under section 2 of the Prevention of Terrorism Act 2005 (“the PTA”). The Secretary of State alleged that each Appellant had been involved in terrorism-related activity. The control orders were confirmed after section 3(10) hearings that relied heavily, and sometimes decisively, on national-security material withheld from the Appellants but disclosed to the court in closed session and to specially appointed security-cleared counsel (“special advocates”).

Each Appellant challenged the orders on the ground that the procedure denied them a fair hearing guaranteed by article 6 of the European Convention on Human Rights, as applied by the Human Rights Act 1998. Their cases proceeded through multiple stages:

• Initial confirmation hearings before Judge Ouseley, Judge Burnton, Judge Mitting and Judge Silber, who reached divergent views on the fairness of the special-advocate process.
• A Court of Appeal decision (majority Judges Clarke MR and Waller LJ; dissent Judge Sedley LJ) largely upholding the Secretary of State’s position and remitting some issues.
• Grant of permission to appeal to the House of Lords, which convened a panel of nine Law Lords.
• Pivotal intervention of the Grand Chamber judgment in A v United Kingdom [2009] ECHR 301, delivered shortly before the House of Lords hearing, resolving key questions about what article 6/5(4) fairness requires when closed material is used.

Legal Issues Presented

1. Whether a section 3(10) control-order hearing that relies solely or decisively on closed evidence breaches article 6 because the controlled person is not told the substance of the case against him.
2. Whether article 6 guarantees a “core, irreducible minimum” of disclosure (the “gist”) that must always be provided, notwithstanding national-security concerns.
3. Whether the “makes-no-difference” principle—i.e. that non-disclosure is permissible if the judge is sure it would not affect the outcome—is compatible with article 6.
4. What effect, if any, the Grand Chamber’s decision in A v United Kingdom has on the interpretation of the PTA provisions and prior House of Lords authority (MB).
5. Whether the PTA can continue to be read down (rather than declared incompatible) so as to preclude reliance on undisclosed material that would render the trial unfair.

Arguments of the Parties

Appellants’ Arguments

• Article 6 (and the common-law right to a fair hearing) entitles a controlled person to be told enough of the allegations to instruct the special advocate effectively; MB should be read as recognising that entitlement.
• The House of Lords had not endorsed any “makes-no-difference” exception; even if it had, such an exception would violate article 6 and should now be rejected.
• Following A v United Kingdom, the Court of Appeal’s approach was unsustainable because each Appellant received only broad assertions incapable of meaningful challenge.
• If necessary, the House should depart from its earlier dicta in MB and adopt the stricter disclosure standard now articulated by Strasbourg.

Secretary of State’s Arguments

• Initially relied on Lord Hoffmann’s minority view in MB: overall fairness can be preserved without a fixed minimum of disclosure, provided the court and special advocate test the closed material.
• After A v United Kingdom, accepted that the Strasbourg judgment must be applied but contended it was consistent with the Court of Appeal’s flexible, fact-specific approach.
• Maintained that the Grand Chamber did not impose an “inflexible” disclosure rule; courts may still find hearings fair where additional disclosure would endanger national security yet make no practical difference.

Special Advocates’ Submissions

• Without client instructions on the essential allegations, special advocates cannot discharge their function of testing the evidence.
• Disclosed material is routinely restricted by broad “class” claims; the existing practice seldom balances the interests of justice against security.
• The Grand Chamber rightly concluded that meaningful participation by the controlled person is indispensable to procedural fairness.

Intervener (JUSTICE)

• Supported the Appellants, arguing that knowledge of the substance of the case is a “solid bedrock of a core legal principle” integral to the judicial function.

Court's Reasoning and Analysis

The House of Lords held that the Grand Chamber’s ruling in A v United Kingdom definitively resolves the key question: a hearing is not fair if the controlled person is given only general assertions while the decisive grounds lie in closed evidence. The essential steps in the House’s analysis were:

1. Article 6 applies to non-derogating control-order hearings because the restrictions are severe and potentially indefinite.
2. A v United Kingdom establishes a rigid principle: the controlee must receive enough information to instruct the special advocate effectively; otherwise the use of closed evidence violates article 6, regardless of how cogent that evidence may be.
3. Earlier domestic authority (MB) permitted courts to decide case-by-case and to rely on a “makes-no-difference” rationale. That approach is no longer tenable.
4. The PTA can still be “read down” (as previously done in MB) so that courts may refuse permission to withhold material when necessary to secure a fair hearing; this avoids an immediate declaration of incompatibility.
5. Applying the Grand Chamber standard, none of the three Appellants had received disclosure sufficient to mount an effective challenge; the hearings were therefore procedurally unfair.

Holding and Implications

Appeals ALLOWED.

The matters are remitted to the respective first-instance judges to require either (a) further disclosure of the essential allegations, or (b) abandonment of the closed material, failing which the control orders must be quashed.

Implications: The decision removes any residual doubt that, in United Kingdom control-order litigation, a minimum level of “gist” disclosure is mandatory. Courts can no longer uphold control orders based “solely or to a decisive degree” on closed evidence. This significantly narrows the circumstances in which the special-advocate procedure alone will satisfy article 6 and may compel the Secretary of State to choose between greater disclosure and the abandonment of some control orders. No broader constitutional principle was altered, but the practical sustainability of the current control-order regime has been placed in doubt.
