Administrative Law
Illegality, Irrationality and Procedural Impropriety
Master the three classic grounds of judicial review, Wednesbury unreasonableness and their relationship with proportionality.
The short answer
A public decision may fail because the authority misunderstood its power, reached an irrational result or used an unfair procedure.
The classic framework
The categories organise analysis but often overlap, so the answer should identify the concrete defect rather than force one label.
Illegality
The authority must correctly understand its jurisdiction and law. Wrong purpose, irrelevant factors, dictation and fettering can all produce illegality.
Irrationality
A decision is reviewable when it falls outside the range a reasonable authority, properly directing itself on law and facts, could reach.
Procedural impropriety
The authority must follow mandatory statutory procedure and natural justice, including impartiality and fair hearing where applicable.
Overlap
Failure to disclose decisive evidence can be procedural unfairness, produce an irrational finding and also violate Article 14.
Wednesbury and proportionality
Both doctrines control unreasonable power, but they ask different questions and operate with different intensity.
Wednesbury restraint
Traditional irrationality does not let the court reweigh merits. It catches outcomes beyond the lawful range of reasonable administrative responses.
Proportionality
Where constitutional rights are restricted, the court may examine legitimate aim, rational connection, necessity and the balance between harm and public benefit.
Evidence and reasons
The more serious the interference, the more important relevant material and intelligible reasons become, even when the court respects expert judgment.
Remedial focus
The court identifies the legal defect and normally restores the choice to administration unless only one lawful outcome remains.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
Tata Cellular v. Union of India
(1994) 6 SCC 651
Facts: The award of cellular-service licences was challenged on the basis that the government's tender evaluation and treatment of bidders were legally defective.
Legal question: How far may courts review administrative and commercial decisions without taking over the merits?
Held: Illegality, irrationality and procedural impropriety provide the classic framework while review remains directed to the decision-making process.
Reasoning: Review examines the process through illegality, irrationality and procedural impropriety while allowing the administration legitimate freedom of contract and policy choice.
Why it matters: Use it to structure almost every general judicial-review answer.
Read the judgmentOm Kumar v. Union of India
(2001) 2 SCC 386
Facts: Government officers challenged the proportionality of disciplinary penalties imposed after findings connected with unauthorised property transactions.
Legal question: How do Wednesbury review and proportionality operate in Indian administrative law?
Held: Indian public law distinguishes traditional Wednesbury review from proportionality analysis, especially where Fundamental Rights are directly restricted.
Reasoning: Traditional administrative review uses the restrained Wednesbury standard, while direct restrictions on Fundamental Rights can attract closer proportionality analysis.
Why it matters: Use it to explain the intensity of review and rights cases.

Rules to retain
- Illegality asks about lawful power.
- Irrationality asks about the lawful range.
- Procedure asks how the decision was made.
- Grounds may overlap.
- Rights can trigger proportionality.
Questions to test understanding
- What does illegality include?
- Why is Wednesbury review demanding?
- What stages form proportionality analysis?
Questions students ask
Is every unreasonable decision Wednesbury irrational?
No. The threshold is not ordinary disagreement. The decision must fall outside the range a reasonable authority could lawfully reach.
When is proportionality especially important?
It is especially important when State action directly restricts a Fundamental Right and the court must examine whether the restriction goes further than necessary.
