Kernrechtsfrage
Whether the appeal was admissible despite the untimely or insufficient procedural filings and non-payment of the advance on costs.
Extrahierter Entscheid
The appeal was inadmissible because the appellant neither paid the advance of costs within the additional deadline nor validly requested reconsideration or extension.
Extrahierte Begründung
Submissions filed after the appeal deadline could not be considered; the later filing before the extended deadline did not amount to a proper request for reconsideration or extension; without payment, inadmissibility followed under the simplified procedure.
