Question juridique clé
Whether the complaint was admissible as a subsidiary constitutional complaint and could be understood as seeking definitive legal opening.
Solution extraite
The filing was admissible as a subsidiary constitutional complaint; the request to dismiss the father's cantonal appeal was inadmissible, but the merits request for definitive legal opening could be read from the reasoning.
Motifs extraits
The case did not reach the ordinary federal appeal threshold, so subsidiary constitutional complaint was the proper remedy. Only the cantonal decision could be challenged before the Federal Supreme Court, and the pleadings had to be interpreted together with the reasoning.
