Noble Organisation Ltd, R (on the application of) v Thanet District Council & Ors

A planning authority’s judgment that it has sufficient information to decide whether proposed development is likely to have significant environmental effects is reviewable only on Wednesbury grounds. Unknown details and other uncertainties do not necessarily prevent a lawful screening decision.

Unchallenged administrative decisions have legal effect unless and until quashed. Once the time for judicial review has passed, an applicant cannot use a challenge to a later planning decision as a collateral challenge to earlier permissions or screening decisions.

Reasonable domestic time limits promote legal certainty and are consistent with the EU principles of procedural autonomy and effectiveness where prompt judicial review provided an effective means of enforcing rights under the environmental impact assessment regime.

The Council granted outline permission for a business park in 1997 and outline permission for a leisure development within that site in 2002. The latter permission followed a reasoned screening decision that an environmental impact assessment was unnecessary. Neither permission nor the earlier screening decision was challenged in time.

In 2004 the Council approved reserved matters for a multiplex cinema after conducting a further screening exercise and again deciding that no assessment was required. Noble, a commercial competitor of an interested developer, sought judicial review of that approval.

Richards J dismissed the claim in [2004] EWHC 2576 (Admin). The appeal concerned the rationality of the later screening exercise, the effect of the formally valid earlier decisions, the EU principles of effectiveness and procedural autonomy, and whether questions should be referred to the European Court under article 234 of the EC Treaty.

1. Appeal dismissed unanimously. The Council’s essential comparison at the reserved-matters stage was with the leisure development authorised by the 2002 outline permission. References to the earlier business park permission were secondary. The Council also examined the characteristics and likely effects of the reserved matters themselves.

2. Whether a planning authority has sufficient information at the outline stage to decide if development is likely to have significant environmental effects is a matter of planning judgment. It is reviewable only on Wednesbury grounds. The authority need not resolve every uncertainty or undertake a detailed assessment of every aspect before deciding that an environmental impact assessment is unnecessary. The description of the leisure development, the site area, illustrative layout and reserved-matters controls supplied enough material for a decision which was not irrational.

3. It was rational to undertake a further screening exercise when reserved matters were submitted. Reserved matters may occasionally go beyond the outline permission or reveal significant effects which were previously overlooked. The Council was entitled, and indeed required, to take the extant outline permission into account as a relevant consideration. Its screening opinion was both comparative and directed to the actual reserved-matters proposal.

4. Administrative acts have legal effect unless and until quashed. The two outline permissions and the 2000 screening decision had not been challenged within the applicable time limits. They therefore stood as valid decisions and could not be attacked directly or collaterally through proceedings against the reserved-matters approval.

5. This domestic rule did not infringe the EU principle of effectiveness. Prompt judicial review had provided an effective remedy against each earlier decision. Reasonable time limits struck a permissible balance between enforcing rights under Council Directive 85/337/EEC, effective planning administration and legal certainty.

6. No reference under article 234 of the EC Treaty was necessary. The Council had in fact reconsidered the need for an assessment at the reserved-matters stage. The principles of procedural autonomy, effectiveness and presumed validity were sufficiently clear, and their domestic application left no reasonable doubt requiring a ruling from the European Court.

1. Court of Appeal (Civil Division): The appeal was dismissed unanimously in [2005] EWCA Civ 782.
2. Administrative Court: Richards J dismissed the claim for judicial review in [2004] EWHC 2576 (Admin), holding that the Council’s reserved-matters approval and screening decision were lawful and that the earlier unchallenged decisions could not be attacked collaterally.
