Key legal question
Whether the cantonal court violated the right to be heard by failing to address the appellant's classification argument.
Extracted holding
Yes. The cantonal court had to explain why it treated the disputed level as an attic floor rather than a roof floor, especially because the two qualifications led to different legal consequences.
Extracted reasoning
The parties had squarely raised the roof-floor qualification. The cantonal court relied on attic rules without discussing the distinction and without giving reasons for rejecting the appellant's position.
