Key legal question
Whether the public-law appeal was admissible against the cantonal judgment and the building permit itself.
Extracted holding
The appeal was admissible against the cantonal judgment, but the request to annul the original building permit was inadmissible because the appeal had devolutive effect.
Extracted reasoning
A final cantonal decision on a building permit can be challenged under the LTF, and the neighbor had standing; however, the lower permit is replaced procedurally by the cantonal appellate judgment.
