Questão jurídica principal
Whether the cantonal appeal proceedings violated the right to be heard because no second exchange or reply opportunity was granted.
Decisão extraída
No violation: a party may reply on its own initiative to received submissions; Quick AG neither requested a reply nor responded.
Fundamentação extraída
The constitutional reply right exists regardless of whether submissions contain new facts or arguments, but it must be exercised promptly; silence can be treated as waiver.
