Question juridique clé
Whether the appeal had to be entered into despite the unpaid advance on costs
Solution extraite
No. Because the appellant neither paid the advance within the final deadline nor proved timely payment by account debit, the Court refused to enter into the appeal.
Motifs extraits
The appellant had been warned under Art. 62(3) BGG that failure to pay within the non-extendable grace period would lead to non-entry. The conditions for payment in cash, at a post office counter, or by duly evidenced debit were not met.
