Kernrechtsfrage
Whether the cantonal decision declaring the challenge inadmissible was an interlocutory decision subject to immediate review.
Extrahierter Entscheid
The decision was interlocutory because it ended only the dispute over the instruction order, not the divorce proceedings themselves.
Extrahierte Begründung
An order on evidence in pending divorce proceedings does not finally dispose of the main case and is therefore incident in nature.
