Question juridique clé
Whether the family council had standing under Art. 420 CC to challenge the guardian’s act.
Solution extraite
The family council lacked standing because it did not show, even plausibly, that it was acting in the ward’s interest; the challenged reasoning was not arbitrary.
Motifs extraits
A third party may appeal under Art. 420 CC only when invoking the protected person’s interests or its own rights/interests that are not the subject of civil proceedings. Here the appellants’ assertions were merely appellatory and did not substantiate concrete adverse effects on the ward.
