Kernrechtsfrage
Whether the appeal was admissible despite the missing attachment of the lower-court decision.
Extrahierter Entscheid
No. The appellant did not cure the formal defect within the deadline set by the court.
Extrahierte Begründung
The required attachment under Art. 42(5) BGG was not submitted in time; the later pickup of the court notice did not change the result because service was deemed effective under the case law on postal retention orders.
