Question juridique clé
Whether the appellant had standing to bring a public-law appeal as a public entity acting as private-law creditor through statutory subrogation
Solution extraite
Yes. In relation to child maintenance, the cantonal authority acts as a private-law creditor and may challenge the cantonal decision by public-law appeal.
Motifs extraits
The maintenance claim remains a private-law claim after statutory subrogation under art. 289(2) CC; the canton does not exercise sovereign power vis-à-vis the debtor but acts as an ordinary creditor.
