Question juridique clé
Whether the Federal Supreme Court could hear an appeal against the Federal Administrative Court's interim decision ordering preparatory safety studies.
Solution extraite
The appeal was inadmissible because the decision was neither a final nor a partial decision, and the conditions for an appeal against an interim decision under Art. 93 BGG were not met.
Motifs extraits
The contested order only prepared future safety measures; no irreparable legal or factual disadvantage was shown, and allowing the appeal would not immediately end the underlying procedure because concrete safety measures still had to be decided later.
