Kernrechtsfrage
Whether the refusal to sever and first decide the duration of separation was an immediately appealable incidental decision.
Extrahierter Entscheid
Yes. The refusal caused irreparable legal harm because it could not be reviewed later with the final divorce judgment.
Extrahierte Begründung
The decision was incidental and not about jurisdiction or recusal; under Art. 93 LTF, irreparable harm existed because the severance refusal could not be cured by a later appeal against the final judgment.
