Question juridique clé
Whether the administrative appeal was admissible against a zoning plan fixing footpaths under federal law
Solution extraite
The administrative appeal was inadmissible because the plan was not directly based on federal law; only the public law appeal was available.
Motifs extraits
The federal footpath statute is a framework law leaving planning to the cantons; the challenged plan was a local planning measure, not a decision under federal substantive law.
