Questione giuridica chiave
Whether the appeal was admissible despite the unpaid advance of costs and the deficient submissions.
Decisione estratta
The appeal was inadmissible because the appellant did not pay the advance within the extended deadline, and his request to pay in installments could no longer be accepted; the submissions also failed to meet minimum legal requirements.
Motivazione estratta
Under Art. 62(3) LTF, non-payment after warning leads to inadmissibility. The court applied the simplified procedure of Art. 108(1)(a) and (2) LTF. It additionally noted that the written submissions did not satisfy Art. 42(2) LTF.
