Question juridique clé
Whether the cantonal court violated the appellants' right to be heard by refusing additional evidence on the neighboring parcel's constructions and distances.
Solution extraite
Yes. The cantonal court ignored a potentially decisive factual element and its anticipatory assessment of the evidence was arbitrary.
Motifs extraits
Because the site plan omitted relevant existing structures on the neighboring parcel and the record did not allow the Federal Court to verify whether the required inter-building distance was met, refusing the requested evidence breached Art. 29(2) Cst.
