Key legal question
Whether the cantonal decision on the road-distance derogation was a final decision or an incidental decision open to immediate federal appeal.
Extracted holding
The challenged cantonal judgment concerned only the derogation and did not end the overall building-permit procedure; it was therefore incidental.
Extracted reasoning
The commune had not yet issued the final building permit. The derogation decision did not itself authorize construction definitively, so the case was not final.
