Question juridique clé
Whether the public law appeal was admissible or excluded in favor of the administrative law appeal
Solution extraite
Only the administrative law appeal was available because the dispute was governed by federal law under LEPM; the public law appeal was inadmissible.
Motifs extraits
Article 11(2) LEPM made the cantonal authorization depend on a corresponding federal postgraduate title, so the case turned on directly applicable federal law.
