The Judgment of Fordham J in R (EXR) v SSHD (2026) EWHC 1568 (Admin) contains a passage as follows:-
“The rubric of judicial review
- Decisions of public authorities must be lawful, in a public law sense. That means – in broad terms – that they must be legal, reasonable and fair. To decide whether they are, the judicial review Court applies objective legal standards. Legality is really concerned with two things: whether the public authority has performed its substantive legal duties; and whether it has made correct conclusions on questions of Fairness is concerned with the legal legitimacy of the public authority’s decision-making process. Reasonableness asks whether an outcome of a decision was beyond the range of responses open to the public authority; and whether the reasoning process involved any recognisable public law error of approach. Sometimes there are nuances and overlaps. There is a species of public law error which involves a material error of an established fact, but nobody says that is relevant to the present case. There is a species of public law error which involves a decision as to a factual question whose lawfulness depends on its correctness, which is highly relevant to the present case.
