Question juridique clé
Whether the appeal against the Federal Administrative Court's non-entry on direct-overflight arguments was admissible as a further appealable decision.
Solution extraite
The decision was an interlocutory decision, but it was separately appealable because waiting for a final decision would cause an irreparable procedural disadvantage in this complex expropriation case.
Motifs extraits
The exclusion from the further ESchK proceedings would have practical effects on the appellants' participation and legal position. Given the long pendency, fair-trial concerns, and equality of arms, immediate review was warranted.
