The case concerned protected bats and a busway
Hampshire County Council granted planning permission for a rapid bus route between Fareham and Gosport. The route followed a former railway corridor used by several species of European protected bats.
The challenge raised both the meaning of prohibited deliberate disturbance under the Habitats Directive and the extent of the planning authority’s duty to have regard to the Directive.
Planning and the protected-species licensing regime
The Supreme Court rejected the proposition that the planning authority must itself perform the role of the species-licensing authority. However, the authority cannot simply ignore the protected-species regime.
The practical question is whether the development is likely to offend a relevant prohibition and, if it is, whether the activity is likely to be licensed. Natural England’s position can therefore be highly relevant to the planning authority’s assessment.
Disturbance is concerned with the protected species
The Court also clarified that the prohibition on deliberate disturbance protects species rather than merely individual specimens. The nature and extent of the negative impact must be assessed; disturbance during breeding, rearing, hibernation or migration may be especially significant.
