Questione giuridica chiave
Whether the federal appeal was admissible after the appellant failed to pay the court advance within the non-extendable deadline.
Decisione estratta
The appeal could not be entered into because the required court advance was not paid or duly evidenced within the deadline.
Motivazione estratta
After warning under Art. 62(3) BGG, the appellant neither paid the advance in cash nor at a post office for the benefit of the Federal Supreme Court, and also failed to submit the required debit confirmation; therefore non-entry followed under Art. 108(1)(a) BGG.
