Kernrechtsfrage
Whether the appeal could proceed despite non-payment of the court advance within the deadline.
Extrahierter Entscheid
The appeal could not proceed and was not entered upon because the advance costs were not paid in time.
Extrahierte Begründung
After an initial and a final non-extendable deadline, the appellant still had not paid the required CHF 800 advance. Under Art. 62(3) BGG, this justified non-entry in simplified proceedings.
