Question juridique clé
Whether the refusal to re-hear the children violated the mother's constitutional rights
Solution extraite
The complaint was inadmissible here because it challenged evidentiary assessment, which had to be raised through the cantonal nullity remedy.
Motifs extraits
A refusal of evidence can be reviewed only as arbitrary fact-finding. Since that grievance belonged to the cantonal nullity appeal and was already addressed there, it could not be examined anew.
