Question juridique clé
Whether the federal nullity complaint against the cantonal decision on testament opening jurisdiction was admissible
Solution extraite
The complaint was inadmissible because the jurisdiction ruling had to be challenged immediately and was no longer open to review together with the later merits decision.
Motifs extraits
A self-standing cantonal decision on jurisdiction in a non-appealable civil matter is a final cantonal decision for purposes of Art. 68 OG. If not appealed immediately, it becomes closed to later attack with the substantive decision.
