Question juridique clé
Whether the administrative law appeal was admissible against a decision on subjection to the passenger transport concession regime.
Solution extraite
The appeal was admissible because the challenged act concerned subjection to the concession regime, not the granting or refusal of a concession.
Motifs extraits
The exclusion in Art. 99(1)(d) OJ did not apply; the decision was a public-law decision under federal law and no special remedy was available.
