Kernrechtsfrage
Whether the appeal complied with the formal requirements of Art. 42 LTF after the court ordered rectification.
Extrahierter Entscheid
The required documents were not filed within the additional deadline, so the appeal did not meet the formal requirements.
Extrahierte Begründung
Under Art. 42(5) LTF, the court must set a suitable deadline to cure missing mandatory annexes, including the challenged decision under Art. 42(3) LTF; failure to comply leads to non-consideration.
