Question juridique clé
Whether the federal complaint had been filed under the correct remedy and was admissible.
Solution extraite
The matter did not concern federal public law; the filing could only be treated as a constitutional complaint, and the ordinary administrative appeal was inadmissible.
Motifs extraits
The underlying claim could, at most, rest on cantonal law, not on federal public law as required for Verwaltungsgerichtsbeschwerde.
