Key legal question
Whether the Federal Supreme Court could hear the appeal despite non-payment of the cost advance within the extended deadline.
Extracted holding
No. The appeal had to be dismissed because the cost advance was not paid within the final deadline and the second extension request was unreasoned.
Extracted reasoning
Under Art. 62 BGG, a cost advance must be paid; if a set grace period expires unused, the court may not enter into the appeal. A second extension is only possible in exceptional, unforeseeable circumstances that must be specifically alleged. The appellant's second request contained no reasons and therefore did not preserve the grace period.
