Questão jurídica principal
Whether the federal appeal met the reasoning requirements of Art. 42 LTF
Decisão extraída
The appeal did not sufficiently challenge all independent grounds of the cantonal judgment and was therefore manifestly inadmissible.
Fundamentação extraída
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.
