Key legal question
Whether the cantonal court violated the right to be heard by relying on post-hearing submissions from the developer.
Extracted holding
No. The post-hearing letter added no genuinely new element on the disputed issue, and the parties had already been able to address the same arguments earlier.
Extracted reasoning
The municipality and developer had already invoked the same case law and planning rationale in their earlier submissions, so the canton court could rely on the later letter without depriving the appellants of an opportunity to respond.
