Kernrechtsfrage
Admissibility of the appeal and late supplementary brief/new evidence
Extrahierter Entscheid
The supplementary brief was late and inadmissible; the new documents and facts could not be considered.
Extrahierte Begründung
The appeal was timely and in principle admissible, but the later filing fell outside the time limit, and the appellant failed to show why new facts and documents would be admissible under the Federal Tribunal Act.
