Key legal question
Whether landowners may sue the municipality before the administrative court for access implementation when a final development plan exists.
Extracted holding
Yes. With a legally binding development plan in place, the landowners could enforce the municipality's access obligation by action before the administrative court.
Extracted reasoning
The parcels lie in the building zone, so the municipality has an access duty under planning law. A binding development plan already specifies the public access solution; the municipality is therefore in default and must implement it according to the plan.
