Legal Principles
Test for departure from outline planning permission: 'significant respect' (Heron Corporation v Manchester City Council).
Heron Corporation v Manchester City Council [1978] 1 WLR 937 at 944C-D
Interpretation of planning conditions: objective correct interpretation (R (Swire) v Canterbury City Council).
R (Swire) v Canterbury City Council [2022] EWHC 390 (Admin)
Flood risk definition: combination of probability and potential consequences (National Planning Policy Framework §167, National Planning Policy Guidance).
National Planning Policy Framework §167, National Planning Policy Guidance
Judicial review: delay is a discretionary bar, especially when exceeding the six-week timeframe (CPR 54.5(5)).
Civil Procedure Rules 54.5(5)
Outcomes
Permission for judicial review refused.
Extreme delay (nearly five years), lack of concealment despite available modelling data, and the Inspector's consideration of flood risk on planning merits.
Leave for statutory review refused.
Inspector's approach to the Parameters Plan, flood risk, and betterment was within the realm of planning judgment and did not constitute errors of law.
