Question juridique clé
Whether the appeal was admissible against the Federal Administrative Court judgment and the BAZL decision
Solution extraite
The appeal was admissible against the Federal Administrative Court judgment, but not insofar as it directly targeted the BAZL decision because only the appellate judgment was the object of review.
Motifs extraits
No statutory exception excluded the public-law appeal; however, due to the devolutive effect, the lower authority's decision could not be directly challenged.
