Kernrechtsfrage
Whether the appeal should be entered into despite non-payment of the advance costs within the final deadline.
Extrahierter Entscheid
The appeal could not be entered into because the advance costs were not paid within the non-extendable grace period.
Extrahierte Begründung
Instalment payments were incompatible with the expedited nature of the proceedings. The request could only be treated as one for partial legal aid, but it lacked sufficient substantiation and evidence of the appellant's financial situation.
