Question juridique clé
Whether the appeal to the Federal Court met the formal reasoning requirements of Art. 42 LTF
Solution extraite
The appeal did not contain sufficient reasoning because it did not challenge the cantonal inadmissibility ruling and only requested an additional deadline to pay the advance on costs.
Motifs extraits
Under Art. 42(1)-(2) LTF, an appeal must state requests and reasons showing briefly why the challenged decision violates the law. The appellant did not address the decisive issue and therefore failed to satisfy the formal requirements.
