Question juridique clé
Whether Fiduciaire Y________ SA had standing to appeal the Federal Administrative Court judgment.
Solution extraite
The company lacked standing because it did not show a legally protected, direct and personal interest; its appeal was therefore inadmissible.
Motifs extraits
Its submission did not satisfy Art. 42(1) LTF and merely invoked a close relationship with X________, which was insufficient to establish appellate standing.
