Question juridique clé
Whether the public-law appeal against the Federal Administrative Court's interim rulings in a US tax assistance case was admissible
Solution extraite
The Federal Supreme Court lacked jurisdiction under the applicable appeal route; the appeal could not be heard.
Motifs extraits
Because the Federal Administrative Court decides finally in this field and Art. 83 lit. h BGG excludes the ordinary public-law appeal, the Supreme Court could not review even the procedural interim decisions. Art. 94 BGG did not create jurisdiction either.
