Key legal question
Whether the appeal could be entered into despite non-payment of the court advance within the extended deadline.
Extracted holding
No. Because the advance costs were not paid even by the extended deadline, the appeal had to be dismissed as inadmissible under the simplified procedure.
Extracted reasoning
The appellant failed to comply with the payment order of 31 January 2012; under Art. 62(3) BGG, non-payment permits non-entry, and the case was decided under Art. 108(1)(a) BGG.
