Judicial Review vs Statutory Appeal: Challenging a Public Authority Decision
Judicial review (CPR Part 54) challenges the lawfulness of a decision-making process; a statutory appeal challenges the merits of the decision within a defined appeal structure. This comparison explains when each is appropriate.
Overview
When a public authority makes a decision that adversely affects you, there are often two potential routes of challenge: judicial review (JR) in the Administrative Court, and a statutory right of appeal to a specialist tribunal or appellate body. Judicial review examines whether the decision was made lawfully — it does not substitute the court's view of the merits for that of the decision-maker. A statutory appeal, where it exists, typically allows a broader examination of the decision, often including the merits. The courts have consistently said that judicial review should be used only where no adequate alternative remedy exists — if a statutory appeal is available, the Administrative Court will generally refuse permission for JR unless there is a good reason to bypass the statutory route.
Side-by-Side Comparison
Judicial Review (JR)
Pros
- Available against any public authority making a public law decision — broad reach
- Wide range of remedies: quashing order, mandatory order, prohibiting order, declaration, injunction
- Can challenge primary legislation as incompatible with HRA 1998 — s.4 declaration of incompatibility
- Can address systemic unlawfulness — court can quash a policy affecting many people
Cons
- Strict 3-month time limit from the date of the decision (CPR r.54.5) — 'promptly and in any event within 3 months'
- Merits are generally not reviewable — court will not substitute its view for the decision-maker's on questions of fact or policy
- Expensive — permission stage, full hearing, and adverse costs risk
- Refused if adequate alternative remedy exists (e.g. statutory appeal tribunal)
Best For
Challenges to unlawfulness in decision-making where no statutory appeal exists, or where the challenge is to the legality of the process or policy rather than the merits of the individual decision.
Statutory Appeal
Pros
- Broader scope of review — specialist tribunal can reconsider the merits of the decision
- Specialist expertise — tribunal knows the subject matter (immigration, tax, planning etc.)
- Lower cost than JR in most cases — tribunal fees are lower and process more accessible
- Often suspensory — an appeal can suspend the effect of the decision pending outcome
Cons
- Limited to the specific statutory grounds of appeal — you cannot raise grounds outside the statutory framework
- Time limits vary — often shorter than 3 months (e.g. immigration appeals: 14 days in-country, 28 days out of country)
- Not available for all public authority decisions — depends on the legislation governing the decision
- Tribunal decision may have limited precedent value; further appeal to Upper Tribunal or Court of Appeal may be needed
Best For
Decisions where Parliament has created a specific appellate structure — immigration decisions, planning appeals, tax assessments, benefits decisions, licensing decisions.
Key Differences
Our Recommendation
Always check whether a statutory appeal is available before issuing judicial review proceedings — the Administrative Court will refuse permission if an adequate alternative remedy exists. Use statutory appeals first: they are cheaper, have broader merits review, and specialist expertise. Reserve JR for: cases where no statutory appeal exists; cases where the statutory appeal does not provide an adequate remedy; challenges to policies rather than individual decisions; and urgent challenges requiring interim injunctive relief pending appeal. Time limits are critical — missing the JR 3-month deadline or the statutory appeal deadline is generally fatal.
