Kernrechtsfrage
Whether the cantonal remand judgment was immediately appealable under Art. 93 BGG.
Extrahierter Entscheid
The remand decision was appealable because the Federal Supreme Court could decide the matter finally if it rejected the existence of a partnership, and the ordered expert evidence would be long and costly.
Extrahierte Begründung
A remand decision generally causes no irreparable legal prejudice, but immediate review is allowed when a favorable ruling would end the case and avoid extensive, expensive evidence. Here the expert had to reconstruct profits over several years and compute the outgoing partner’s share, which made the proof-taking burden unusually heavy.
