Key legal question
Whether the refusal of a personal hearing and additional evidence violated the right to be heard
Extracted holding
No. Written submissions and on-site inspection were sufficient; no right to oral hearing existed, and the refusal of further evidence was not arbitrary.
Extracted reasoning
Art. 29(2) Cst. does not guarantee an oral hearing. The court could anticipate that the requested witness hearing and water-quality expert evidence were irrelevant to the outcome.
