Question juridique clé
Whether the cantonal court's remand decision was a separately appealable final/partial decision on site suitability under Art. 24 lit. a RPG.
Solution extraite
The ruling on site suitability could be treated as a partial final decision, but the court should not have separated it from the overall balancing required for the permit decision.
Motifs extraits
For mobile antennas, site suitability and the broader interest balancing overlap so closely that they cannot be cleanly separated in this case; a standalone decision would be premature.
