Kernrechtsfrage
Whether the appellant was entitled to an additional time limit to complete the appeal
Extrahierter Entscheid
No. The appeal was filed within the statutory time limit, so extending the deadline would unlawfully prolong the legal appeal period.
Extrahierte Begründung
A supplementary filing is only expressly provided in limited situations; a time extension cannot be granted merely to improve the reasoning of a timely appeal, and restitution of time is irrelevant because the deadline was respected.
