R v North and East Devon Health Authority, ex p Coughlan [2001] QB 213
R v North and East Devon Health Authority, ex p Coughlan is the leading case on substantive legitimate expectation. A clear promise made to a small group may be enforced where departure would be so unfair as to amount to an abuse of power.
Facts
Miss Coughlan was severely disabled in a road accident and required long-term nursing care. After her hospital ward closed, the health authority persuaded her and other residents to move to Mardon House, a purpose-built NHS facility. They were repeatedly assured that Mardon would be their home for life. Several years later, the authority decided to close it and transfer residents elsewhere, citing changing policy and cost. Miss Coughlan sought judicial review. The authority had consulted about closure, but the central dispute was whether its express promise created a substantive expectation that could outweigh its later assessment of public needs and resources.
Legal Issue
Did the promise of a home for life create an enforceable substantive legitimate expectation, and would closing Mardon House be an abuse of the health authority's power?
Held
The Court of Appeal allowed Miss Coughlan's claim. The assurances were clear, unambiguous and devoid of relevant qualification, and were directed to a small, identifiable group whose members had relied on them in accepting the move. The court distinguished three situations: a policy change reviewable on ordinary public-law grounds; an expectation of consultation or another procedure; and an expectation of a substantive benefit. In the third category, the court weighs fairness against any overriding public interest and may enforce the promise where frustration would be so unfair as to constitute abuse of power. The health authority had not shown a sufficient public-interest justification for breaking its specific promise.
⭐ Legal Principle
A clear and unqualified public-authority promise may create a substantive legitimate expectation. Where the promise concerns a specific benefit for a limited group, the court balances the resulting unfairness against any overriding public interest and may enforce it if departure would be an abuse of power.
Significance
Coughlan established substantive legitimate expectation as a distinct ground of judicial review and remains the standard framework for promises by public bodies. Later cases emphasise that the representation must be sufficiently clear, that the claimant's knowledge and circumstances matter, and that government retains greater freedom where broad policy and many affected people are involved. Reliance strengthens a claim but is not invariably a formal prerequisite. R (Nadarajah) v Secretary of State for the Home Department later connected the doctrine to consistency and good administration.
Common exam questions about this case
Why was the promise to Miss Coughlan particularly strong?
It was repeatedly expressed as a promise that Mardon House would be her home for life, contained no relevant qualification and was made to a small group in circumstances where residents accepted relocation. It therefore went beyond a general policy statement and generated a focused expectation whose frustration caused acute unfairness.
What three situations did the Court of Appeal distinguish in Coughlan?
The court distinguished a general policy change, which receives conventional public-law review; a promise of a procedure such as consultation; and a promise of a substantive benefit. The intensity of review differs because courts allow wider administrative choice over broad policy than over a specific assurance made to a limited group.
Does a substantive legitimate expectation always bind the public authority?
No. Even a sufficiently clear promise may yield to an overriding public interest. The court evaluates the authority's reasons and the unfairness of departure within the appropriate institutional context. Coughlan succeeded because the assurance was exceptionally specific and the authority's resource and policy reasons did not justify breaking it.
