Question juridique clé
Whether the appeal satisfied the Federal Supreme Court's motivation requirements.
Solution extraite
No. The filing contained no substantiated legal arguments and merely announced that reasons would be filed later, which is not permitted after expiry of the appeal period.
Motifs extraits
Under Art. 42(1)-(2) LTF, the appeal must itself state concisely how the challenged decision violates the law. A later supplement cannot cure a completely unreasoned filing once the time limit has expired.
