Key legal question
Whether the cantonal court arbitrarily refused to apply the plan regulation requiring contiguous construction in perimeter A6.
Extracted holding
Yes. The project lay in a zone where contiguous construction was mandatory, so the cantonal court could not rely on non-contiguous-building logic to deny the permit.
Extracted reasoning
The plan and regulation made contiguity compulsory within perimeter A6; the depth of construction was determined by that perimeter. The cantonal court's contrary reading was insustainable and arbitrary in result.
