Kernrechtsfrage
Whether the Federal Supreme Court could entertain a request to reinstate the cantonal advance-payment deadline under Art. 148 ZPO.
Extrahierter Entscheid
The request was inadmissible before the Federal Supreme Court because reinstatement of cantonal deadlines must be decided by the cantonal courts.
Extrahierte Begründung
The competence to decide requests for reinstatement of a cantonal procedural deadline lies with the cantonal judiciary, not the Federal Supreme Court.
