Key legal question
Whether the appeal could proceed despite non-payment of the court advance within the deadline.
Extracted holding
The appeal could not proceed and was not entered upon because the advance costs were not paid in time.
Extracted reasoning
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.
