Questione giuridica chiave
Whether the federal appeal met the reasoning requirements of Art. 42 LTF
Decisione estratta
The appeal did not sufficiently challenge all independent grounds of the cantonal judgment and was therefore manifestly inadmissible.
Motivazione estratta
The appellants failed to address the cantonal finding that their request to extend the fee-advance deadline was filed late, which alone was sufficient to uphold inadmissibility.
