Questão jurídica principal
Whether the evidence requests and on-site inspection were wrongly refused in violation of due process.
Decisão extraída
No. The cantonal court could deny further evidence by anticipatory assessment because the existing record already allowed it to decide, and the appellants did not show that additional evidence would likely change the result.
Fundamentação extraída
The letters submitted did not show a building permit, and the appellants did not explain why archival inquiries or an inspection would yield decisive additional facts.
