Summary
Disclosure remains exceptional rather than routine in judicial review. The court must apply a flexible, case-specific test. It should order disclosure only where this is necessary to determine the proceedings fairly and justly. An applicant need not first demonstrate that the public authority’s evidence is contradictory, inaccurate or incomplete.
A proportionality challenge may require closer factual scrutiny and therefore increase the need for disclosure, but it creates no automatic entitlement. Documents relied upon and summarised by a public authority should ordinarily be exhibited because the originals are the best evidence. Confidentiality may justify restricted disclosure, redaction or judicial inspection, but does not exclude the court’s power to order disclosure. The court must balance fairness, relevance, confidentiality, burden, available alternative material and the proper latitude afforded to the decision-maker.
Factual background
Tweed v Parades Commission for Northern Ireland concerned an interlocutory application within judicial review proceedings challenging restrictions imposed upon an Orange Order procession. The appellant alleged disproportionate interference with rights protected by articles 9, 10 and 11 of the European Convention for the Protection of Human Rights and Fundamental Freedoms.
The Commission’s chairman had summarised five police, secretariat and authorised-officer documents which had informed the determination. The appellant sought their disclosure. Girvan J ordered disclosure, subject to any public interest immunity issue. The Court of Appeal in Northern Ireland, in [2005] NICA 42, set that order aside as premature pending determination of the validity of the Commission’s confidentiality rule.
The central issue before the House was how courts should approach disclosure in judicial review, particularly where the legality of an interference with Convention rights depended upon proportionality and the underlying documents contained information supplied in confidence.
Held
Disposition. The House unanimously allowed the appeal. Lord Carswell and Lord Brown gave the principal reasons. Lord Bingham agreed and added observations. Lord Hoffmann and Lord Rodger agreed with all three speeches.
General approach to disclosure. Per Lord Carswell and Lord Brown, routine disclosure remains inappropriate in judicial review because such proceedings ordinarily concern legal issues and agreed or documented facts. The former restrictive rule, under which disclosure could not be ordered without material suggesting contradiction, inconsistency or incompleteness in the respondent’s evidence, should no longer apply. The court must instead determine flexibly whether disclosure is necessary for fair and just disposal of the particular case. The duty of candour and the need to prevent fishing expeditions remain important safeguards.
Proportionality cases. Per Lord Carswell and Lord Brown, proportionality introduces a more intensive review and may require closer examination of the factual justification for interference with qualified Convention rights. It does not convert judicial review into merits review or create an automatic right to disclosure. The court must consider the required intensity of review, the latitude due to the decision-maker, the relevance and specificity of the documents, alternative sources of information, expense, volume and confidentiality. Courts may show greater readiness to order disclosure of central documents where the decision-maker has a narrow margin of discretion.
Documents mentioned in evidence. Per Lord Bingham, a public authority relying upon a significant document should ordinarily exhibit it as the best evidence. An applicant seeking the original need not identify an inaccuracy in a summary without having seen the document. Lord Carswell held, approving Dubai Bank Ltd v Galadari (No 2) [1990] 1 WLR 731, that an affidavit procured and used on behalf of a party falls within the inspection rule concerning that party’s affidavits. Sufficient reasons against production may include confidentiality, excessive volume or public interest immunity.
Confidentiality and the order made. The Commission’s rule 3.3 did not prevent the court from ordering disclosure where justice required it. Applying the procedure in Science Research Council v Nassé [1980] AC 1028, the five documents were to be disclosed first to the judge alone. The judge was to assess whether they materially added to the summaries. If they did, the judge would consider disclosure to the appellant, redaction and then any public interest immunity claim. If they added nothing material, inspection by the appellant could be refused.
