Network Rail Infrastructure Ltd v Welsh Ministers

A statutory challenge to a definitive map modification order attracts the ordinary principles of judicial review. The court reviews legality, rationality, relevant considerations, procedural fairness and adequacy of reasons, but does not reweigh evidence or substitute its own view on factual matters entrusted to the inspector.

Reasons are adequate where, read fairly and in context, they identify the main issues and leave no genuine doubt about what was decided and why. A material error of fact requires an established and objectively verifiable factual mistake, for which the applicant is not responsible, that materially influenced the decision. An inspector need not disclose provisional views or invite comment on internal reasoning before issuing the decision.

An inspector appointed by the Welsh Ministers confirmed a definitive map modification order under the Wildlife and Countryside Act 1981. The order recorded a public footpath crossing land owned by Network Rail Infrastructure Ltd and two railway branch lines.

Network Rail challenged the decision under Schedule 15, paragraph 12 of the Act. It alleged irrationality, material error of fact, failure to take account of material considerations, inadequate reasons, and procedural or substantive unfairness. The central issue was whether the inspector was entitled, on the documentary evidence, to find that a public route existed and had been used before construction of the railway.

1. Outcome. The claim was dismissed. The inspector’s confirmation of the order stood.
2. The statutory challenge under Schedule 15, paragraph 12 of the Wildlife and Countryside Act 1981 engaged the ordinary principles of judicial review. The court would not reargue the merits, reassess the weight given to evidence, or substitute its own factual judgment.
3. The inspector was entitled to infer from the maps, railway plans, documentary material and later physical arrangements that a route giving access to the foreshore probably existed before the railway was authorised and constructed. Post-railway evidence could properly be considered as evidence bearing on earlier use. The conclusion was finely balanced but rationally open to the inspector.
4. The alleged errors of fact concerned inferences from documentary evidence rather than uncontentious, objectively verifiable facts. The additional alleged error, concerning the claimed motivation for the application, could not have materially affected the reasoning.
5. The inspector had considered the material matters relied upon. She was not required to address every item of evidence or explain the weight assigned to each point. Her reasons, read as a whole, addressed the principal issues and did not create genuine rather than forensic doubt about the decision or its basis.
6. Natural justice did not require the inspector to disclose her provisional conclusions or invite submissions on her internal evaluation of the evidence. The consultation paper had been cited in the claimant’s case, and the guidance relied upon was generic and immaterial to the decisive reasoning. Reliance on it did not create procedural unfairness.
7. The evidence did not establish any of the five grounds of challenge. Consequential matters were left to written submissions within 14 days of hand-down.
