Question juridique clé
Whether the federal appeal was admissible despite the absence of cantonal approval of the building-line plan and the lower court's refusal to decide the merits.
Solution extraite
The appeal was admissible insofar as it challenged the standing ruling; the cantonal court's decision was treated as a final decision because the refusal to enter on the matter ended the proceedings.
Motifs extraits
Coordination between plan approval and remedy proceedings must be ensured by the last cantonal instance under Art. 25a RPG; the approval decision should be obtained before the final cantonal appeal court. A non-entry-type ruling is final even if issued in an appellate setting.
