Question juridique clé
Whether the federal appeal had to be entered into despite non-payment of the advance on costs.
Solution extraite
No entry was possible because the advance payment was not made within the prescribed period after due warning.
Motifs extraits
The case was cost-bearing; the appellant was ordered to pay CHF 900 within 14 days, warned of non-entry, and the payment was still not made even taking the statutory standstill into account. Under the warning and Art. 150(4) OG, non-entry followed.
