Kernrechtsfrage
Whether the federal appeal filed by fax was admissible
Extrahierter Entscheid
No. Appeals to the Federal Supreme Court must be filed in the legally prescribed form; a fax submission does not satisfy this requirement.
Extrahierte Begründung
Art. 48(1) BGG requires filing by hand delivery or postal submission, or electronically with qualified signature under Art. 42(4) BGG. The appellant did not cure the defect by submitting a postal appeal within the 30-day time limit.
