Key legal question
Whether the Federal Supreme Court could enter into the complaint despite non-payment of the court cost advance within the extended deadline.
Extracted holding
No. Because the ordered cost advance was not paid even within the grace period, the complaint could not be examined.
Extracted reasoning
Under Art. 62(3) BGG and Art. 108(1)(a) BGG, failure to pay the required advance after a set deadline leads to non-entry.
