Key legal question
Whether the cantonal court committed a denial of justice by refusing to examine the merits of the request for restoration of lawful status, use prohibition, and after-the-fact building control.
Extracted holding
Yes. Because the building plans did not clearly disclose the ramp's above-ground course, the neighbours could not effectively object earlier; the cantonal court had to address the merits.
Extracted reasoning
Only what is sufficiently clear from the plans can become part of a valid permit. Here the plans did not show the eastern exit ramp's elevation and relation to the terrain with sufficient clarity, especially given the topography; thus the neighbours' later complaint was timely in substance.
