Kernrechtsfrage
Whether the Federal Supreme Court appeal against the cantonal ruling was admissible under Art. 93 LTF.
Extrahierter Entscheid
The challenged ruling was an incidental decision; no irreparable legal harm was shown, so the appeal was inadmissible.
Extrahierte Begründung
The appellant relied on privacy and banking secrecy interests belonging to the deceased, not to himself. The respondent, whose disinheritance is contested, may access information needed to challenge the testament, so disclosure of the expert report caused no irreparable harm to the appellant.
