Questione giuridica chiave
Whether the appeal against the cantonal inadmissibility decision was admissible under Art. 93 LTF.
Decisione estratta
The challenged ruling was an incidental decision and the appellant failed to show any irreparable legal prejudice; the appeal was therefore inadmissible.
Motivazione estratta
The restored deadline only gave the claimant a new chance to contest relief; any prejudice to the defendant was merely temporary and could still be reviewed after a later decision on relief, including under Art. 93(3) LTF.
