Kernrechtsfrage
Whether the defendant was unworthy to inherit under Art. 540 ZGB because she allegedly destroyed or invalidated testamentary dispositions.
Extrahierter Entscheid
The alleged ground of unworthiness was not proven; the defendant was not unworthy to inherit.
Extrahierte Begründung
Unworthiness must be based on a statutory ground that is established in fact. The cantonal court found no proof of manipulation, unlawful influence, or destruction of testamentary dispositions, and the Federal Court was bound by those factual findings.
