Questione giuridica chiave
Whether the appeal could proceed despite the unpaid court advance
Decisione estratta
No. Because the appellants neither paid the advance in cash nor proved timely debiting to a Swiss account within the deadline, the court had to refuse entry.
Motivazione estratta
After a warning under Art. 62(3) BGG, failure to comply with the non-extendable deadline triggered non-entry under Art. 108(1)(a) BGG.
