Key legal question
Whether the appeal had to be entered into despite non-payment of the court advance within the extended deadline.
Extracted holding
The appeal could not be entered into because the appellant neither paid the advance in time nor proved timely payment by bank/post debit confirmation.
Extracted reasoning
After warning under Art. 62 Abs. 3 BGG and expiry of the non-extendable grace period, the conditions for entering into the appeal were not met.
