Key legal question
Whether the public law appeal was admissible against the cantonal judgment annulling the building permit
Extracted holding
The appeal was inadmissible, regardless of whether the cantonal judgment was viewed as a final decision or a remand-type incident decision.
Extracted reasoning
If treated as an incident decision, it caused no irreparable harm; if treated as final, the appellants lacked standing because the cantonal judgment gave them full relief by annulling the permit.
