Key legal question
Whether the civil complaint was admissible despite the appellants lacking an actual and practical interest after the cantonal court had already annulled the guardianship measure.
Extracted holding
The appellants no longer had a current and practical legal interest in challenging the cantonal judgment, because their appeal below had already succeeded in substance.
Extracted reasoning
Standing under Art. 76 BGG requires a legally protected interest, which in practice means an actual and practical interest at the time of the federal appeal. Since the district court had granted the relief sought by annulling the guardianship, there was no remaining interest in reviewing that decision.
