Question juridique clé
Whether the cantonal court misunderstood the effect of the Federal Court's earlier judgment and unlawfully reopened the validity of the inheritance contract.
Solution extraite
The objection failed; the earlier federal judgment had not finally decided the validity issue, so the cantonal court had to decide it again.
Motifs extraits
Only the loan claim had become final; the invalidity of the inheritance contract remained open after the Federal Court later also set aside the second cantonal judgment.
