Questione giuridica chiave
Whether the appeal had to be entered into despite non-payment of the court advance within the deadline.
Decisione estratta
No; because the advance costs were not paid and proof of timely payment was not filed, the appeal could not be considered.
Motivazione estratta
The appellant ignored the non-extendable deadline set under Art. 62(3) BGG; under Art. 108(1)(a) BGG the court therefore issued a non-entry decision.
