Question juridique clé
Whether the cost ruling in the cantonal remand decision could be challenged by administrative law appeal
Solution extraite
No. Because the contested point concerns only a cantonal cost order, administrative law appeal is unavailable when only the costs point is attacked.
Motifs extraits
The cost order rests solely on cantonal procedural law and was challenged in the federal court without any attack on the substantive federal-law planning ruling. In that situation, only a constitutional complaint could be considered.
