Judicial Review & Immigration
10,911 cases · March 1998 to July 2026
Overview
Judicial Review & Immigration appears in 10911 reported Hong Kong judgments (1998–2026).
Challenges to government and public-body decisions, including immigration, asylum, non-refoulement and human-rights claims.
Judicial review is the mechanism by which the Hong Kong courts supervise the legality of decisions made by the government and other public bodies. In principle it reaches across the whole of public administration, testing whether a decision-maker acted within its powers, followed a fair procedure, and reached a conclusion open to it on the law. In practice, the raw volume of this area is overwhelmingly concentrated in one stream: applications challenging the rejection of non-refoulement and torture claims. Such applications are by far the largest component of the caseload, are filed in very high volume, and are frequently brought by applicants acting in person without legal representation. The remainder of the area covers challenges to immigration and asylum decisions more generally, together with human-rights and other public-law grievances.
Most applications begin in the Court of First Instance, where a claimant must first obtain leave before a substantive hearing can proceed. Refusals and substantive rulings may be taken to the Court of Appeal, and points of general public importance may ultimately reach the Court of Final Appeal, the apex court since Hong Kong's return in 1997. The District Court features in a narrower set of related matters.
The appellate courts have set out the proper approach to leave in non-refoulement judicial reviews, as reflected in [2024] HKCA 1140, [2024] HKCA 1090 and [2024] HKCA 95, with [2025] HKCA 705 continuing that line. Broader constitutional and human-rights questions have been addressed at the highest level, as in [2023] HKCFA 28.
About this area's case volume
This area covers challenges to government and public-body decisions — including immigration, asylum, non-refoulement and human-rights claims. Its case count is by far the largest in the taxonomy because it is dominated by non-refoulement judicial-review applications (the Court of First Instance "HCAL" list), which are filed in very high volume and are frequently brought by applicants in person. The counts and court distribution below reflect that concentration; the top cases are ordered by how often they are cited by later judgments, which surfaces the leading authorities within the area.

Which court hears judicial review applications in Hong Kong?
Judicial review applications are heard in the Court of First Instance, where a claimant must obtain leave before a substantive hearing. Decisions may be appealed to the Court of Appeal and, on points of general public importance, to the Court of Final Appeal.
What does judicial review of a non-refoulement claim involve?
It is a challenge to the legality of a decision rejecting a claim for protection against removal, typically a decision of the Torture Claims Appeal Board or the immigration authorities. The court examines whether the decision was lawful, procedurally fair and rationally reached, rather than re-deciding the underlying claim itself.
Why is non-refoulement litigation such a large part of this area?
Applications challenging rejected non-refoulement and torture claims are filed in very high volume and are frequently brought by applicants in person, so they dominate the recorded caseload even though judicial review as a doctrine extends to public decisions generally.
