Questione giuridica chiave
Whether the appeal met the formal requirements under Art. 42 BGG and could be entered into.
Decisione estratta
The appeal did not contain any request and did not engage specifically enough with the cantonal court's reasoning; therefore it was not a valid legal remedy within the time limit.
Motivazione estratta
A federal appeal must include requests and reasoning showing, in a concise manner, how the challenged decision violates law. The appellant failed to address the decisive reasoning and did not sufficiently challenge the relevant factual findings under Art. 97(1) BGG, despite being warned that defects could only be cured within the appeal period.
