Question juridique clé
Whether the bank had standing to file a guardianship complaint under Art. 420 ZGB on behalf of the protected person.
Solution extraite
Standing under Art. 420 ZGB is limited to close persons when the third party invokes the protected person's interests; the bank did not qualify as such.
Motifs extraits
The court interpreted 'any interested person' in Art. 420 ZGB, in harmony with Art. 397d ZGB, as requiring a sufficiently close relationship if the complaint is brought to protect the ward's interests. A mere bank-customer relationship without special proximity is not enough.
