Solution extraite
No entry was possible because the procedural defect was not remedied within the deadline set by the court.
Motifs extraits
The court had pointed out the missing authorization under Art. 42(5) BGG and warned that the filing would be disregarded if not corrected. Since the defect remained uncured, the appeal was manifestly inadmissible.
