Kernrechtsfrage
Whether the complaint had to be dismissed because the appellant did not return a signed version within the non-extendable deadline set by the Court.
Extrahierter Entscheid
Yes. The appellant did not comply with the order to submit a signed complaint within five days, so the Court could not enter on the appeal.
Extrahierte Begründung
The Court had warned that non-compliance would lead to non-entry under Art. 42(5) BGG. The service of the order was deemed completed on the last day of the postal pickup period under Art. 44(2) BGG, and no signed complaint was filed in time.
