Question juridique clé
Whether the appeal could be heard despite non-payment of the court advance.
Solution extraite
No; because the advance on costs was not paid within the set time limit, the Court would not enter into the appeal under Art. 108 BGG.
Motifs extraits
The appellant had been warned that failure to pay the CHF 750 advance by the deadline and grace period would lead to non-entry. Since payment was not made, the appeal had to be dismissed procedurally.
