Question juridique clé
Whether the cantonal court violated the ban on excessive formalism by declaring the appeal inadmissible for non-payment of the advance on costs
Solution extraite
No. The appellants could and should have understood that two separate appeals triggered two separate advance payments; the sanction of inadmissibility was not excessively formalistic.
Motifs extraits
The letters clearly identified the case and decision, were accompanied by payment slips, and warned of the consequence of non-payment. Without an equivalent cantonal rule to Art. 62(3) LTF, the court was not required to grant an additional grace period.
