Kernrechtsfrage
Whether the adoption could be challenged under Art. 269 or 269a CC for lack of consent or a serious defect.
Extrahierter Entscheid
The adoption was not challengeable on the asserted grounds; later-life changes and the wish to establish a legal tie with the biological father do not constitute a statutory defect.
Extrahierte Begründung
Art. 269 CC requires missing consent existing at the time of adoption; Art. 269a CC allows only pre-existing serious defects. Post-adoption developments are excluded, and the adoption’s unassailability reflects the purpose of plenary adoption.
