Question juridique clé
Whether the cantonal refusal of party compensation under § 201 VRG/LU was arbitrary or violated federal law.
Solution extraite
The refusal was not arbitrary and did not violate federal law.
Motifs extraits
Federal law allows review only for arbitrariness. Section 201 VRG/LU distinguishes between adversarial appeals and other proceedings; an 'manifest violation of law' is not equated with any legal error. Given the complexity of the case, the existence of arguable reasons for the cantonal view, and the federal office's similar position, the refusal was defensible.
