Kernrechtsfrage
Whether the appeal had to be dismissed for failure to provide the ordered security for costs within the deadline.
Extrahierter Entscheid
The appeal could not be entered because the appellant did not pay the security within the non-extendable grace period.
Extrahierte Begründung
After the request for security was upheld and a deadline set, the appellant neither paid cash to the Federal Supreme Court nor deposited the amount at a post office in time; under the warning given, Article 62(3) BGG required non-entry under Article 108(1)(a) BGG.
