Kernrechtsfrage
Whether the appellant could obtain an extension of the statutory appeal deadline to complete the appeal
Extrahierter Entscheid
No. The appeal deadline is a legal time limit and cannot be extended; a supplementary filing was not available on these facts.
Extrahierte Begründung
The Court held that only the situations expressly provided by the LTF allow supplementary submissions or curing formal defects, and none applied here. An extension cannot be granted merely to improve the reasoning of a timely appeal.
