Court of Appeal expands document disclosure in judicial review proceedings

The Court of Appeal has signalled a significant shift in how documents must be produced in judicial review proceedings, moving away from a narrower interpretive framework that has long constrained access to information sought by applicants.

In its ruling, the appellate court determined that the traditional 'relevancy' test—which previously governed what materials could be required for disclosure—no longer represents the applicable standard for judicial review discovery. This change opens pathways for litigants to obtain a broader range of documents from government agencies and other parties involved in administrative decisions.

The court also firmly rejected arguments that discovery requests should be denied simply because they constitute a 'fishing expedition'—a characterisation often used to block document requests perceived as exploratory or unfocused. By removing this barrier, the decision makes it more difficult for respondents to resist disclosure demands based solely on concerns about the breadth of such requests.

The ruling reflects evolving judicial thinking on transparency and access to information in administrative law matters, potentially strengthening the grounds on which citizens can challenge government decisions through the courts. Legal practitioners expect the decision will have practical implications for how judicial review cases are conducted going forward, particularly regarding the discovery phase of litigation.

The expanded access standard aligns judicial review procedures more closely with principles of procedural fairness and administrative accountability, though courts will likely continue to apply proportionality considerations in determining which documents must ultimately be produced.
