Kernrechtsfrage
Whether the deadline for submitting the missing lower-court decision should be restored under Art. 50 BGG.
Extrahierter Entscheid
The requirements for restoration were not met because the omission was attributable to counsel's own lack of attention, not to an excusable impediment.
Extrahierte Begründung
A restoration requires an unexcused impediment and timely request plus completion of the missed act. Here, counsel had been expressly warned of the missing attachment and, after the first error, had to exercise greater care; the misunderstanding remained his own fault.
