Tesco Stores Ltd v Dundee City Council (Scotland)
Factual and Procedural Background
Company A and Company B (the interveners) applied to the Respondent (the planning authority for The City) for permission to redevelop a long-vacant industrial site into a large food superstore, café and petrol filling station, together with associated infrastructure. Although the proposal conflicted with parts of the applicable structure and local plans—particularly employment-land protections and retail policies—the Respondent considered that significant economic and planning benefits justified approval.
The Appellant, a competing retailer, sought judicial review, alleging that the Respondent had misunderstood the “sequential approach” contained in the development plan, thereby vitiating its decision to depart from the plan. The challenge was dismissed at first instance and by the appellate court in Scotland. The present judgment, delivered by Judge Reed (with Judge Brown, Judge Kerr, Judge Dyson and Judge Hope concurring), addresses the Appellant’s further appeal.
Legal Issues Presented
- Whether the Respondent misinterpreted the development plan’s requirement that “no suitable site” be available in sequentially preferable locations before out-of-centre retail development can be approved.
- Whether the court or the planning authority has primary responsibility for determining the meaning of development-plan policies.
- If a misinterpretation occurred, whether it was material so as to invalidate the planning permission.
Arguments of the Parties
Appellant's Arguments
- The word “suitable” in the sequential policy means “suitable for meeting identified retail deficiencies,” not “suitable for the developer’s specific proposal.”
- By treating suitability as proposal-specific, developers can design schemes so large that only out-of-centre sites qualify, defeating the sequential approach.
- The Respondent therefore understated the extent of conflict with the development plan and reached a flawed balance when deciding that other considerations justified departure.
Respondent's Arguments
- Interpretation of planning policy lies primarily within the planning authority’s planning judgment; the court should intervene only if the view adopted is irrational.
- All criteria in the policy had to be satisfied. The Respondent had already found non-compliance with other criteria, so any alleged misunderstanding of the first criterion was immaterial.
- A flexible, realistic assessment was undertaken: alternative town-centre sites down to 2.5 ha (well below the 6.68 ha application site) were evaluated, and the nearest candidate was still far too small and lacked parking.

Court's Reasoning and Analysis
1. Court’s interpretative role. Judge Reed held that while planning authorities exercise judgment on factual application of policies, the meaning of policy wording is an objective question of law for the courts. Sections 25 and 37(2) of the 1997 Act would be undermined if each authority could ascribe its own meaning subject only to irrationality review.
2. Meaning of “suitable”. Reading the structure plan, local plan and national guidance as a whole, the court concluded that “suitable site” refers to a site suitable for the proposed development, subject to the flexibility expected of developers (e.g., consideration of smaller formats). Interpreting it as “suitable for meeting retail deficiencies” would collapse the first and third criteria into one and contradict national guidance emphasising developer requirements.
3. Application to the facts. The interveners had examined sequentially preferable sites down to 2.5 ha, including the Appellant’s vacated town-centre site of 1.45 ha, and none could accommodate even a reduced version of the proposal with adequate parking. The Respondent therefore acted within the policy.
4. Materiality. Even if there had been a misinterpretation, the court found no real possibility that the decision would have differed. The economic and planning benefits were substantial and site-specific, and the proposal already conflicted with other retailing criteria, making any further conflict immaterial to the ultimate balancing exercise.
Holding and Implications
APPEAL DISMISSED.
The Supreme Court affirmed that “suitable site” in the sequential approach relates to the developer’s proposal, not to hypothetical scaled-down schemes, and clarified that courts, not planning authorities, have the final say on interpreting planning policies. The decision leaves the granted planning permission intact and underscores the need for flexibility in applying sequential tests while preventing authorities from redefining policy language case by case. No new precedent was set on the substantive outcome of planning balances, but the judgment provides authoritative guidance on the division of interpretative responsibility between courts and planning authorities.
