Questione giuridica chiave
Whether the complaint was admissible despite non-payment of the advance on costs within the set deadline.
Decisione estratta
No; the complaint could not be entered into because the advance on costs was not paid and the required proof of timely payment was not submitted.
Motivazione estratta
After a first extension and a non-extendable grace period under Art. 62(3) BGG, the appellant still neither paid the advance in cash nor provided the required debit confirmation. The complaint was not withdrawn, so non-entry followed under Art. 108(1)(a) BGG.
