The duty of candour requires a public authority defending a judicial review claim to disclose documents and information relevant to the issues, including material that harms its case. It is not limited to what the claimant has already asked for.
In practice, the quality of disclosure often turns on how clearly the claim identifies the decision and the grounds. Vague pleadings produce vague bundles. Precise ones make incomplete disclosure harder to justify.
We help claimants frame requests and pleadings so that the duty has something concrete to bite on, and we advise respondents on what a compliant response looks like.
