Key legal question
Whether the constitutional complaint was admissible despite the appellant not being the addressee of the cantonal decision
Extracted holding
No. Only a person directly affected by the challenged decision has a legally protected interest under Art. 115 lit. b BGG; the decision was issued against A., not against the appellant.
Extracted reasoning
Because the cantonal decision concerned A. and not the estate, the appellant lacked personal legal injury and therefore standing to challenge it.
