Question juridique clé
Whether the refusal to hold an on-site inspection violated the right to be heard or cantonal procedural law.
Solution extraite
No. The file was sufficient, and no pertinent fact required a site inspection.
Motifs extraits
The relevant factual elements were ascertainable from the plans and the record; the decisive legal questions turned on the planning rules and the effect of the proposed conversion, so the cantonal court could lawfully refuse further evidence by anticipatory appreciation.
