Whether A.T.________ and B.T.________ had standing as interested parties to appeal the refusal to open a guardianship inquiry against H.________.
No. A third party has standing under Art. 420 CC only if acting in the ward's interest or asserting rights protected by guardianship law; creditors pursuing their own interests are excluded.
The appellants sought to protect only their own creditor interests, which are not protected by guardianship law. They therefore lacked the required interest and their appeal was inadmissible.
