Kernrechtsfrage
Whether the cantonal supervisory authority had jurisdiction to decide the dispute over the contractual terms of the pensioners' transfer.
Extrahierter Entscheid
No; the dispute concerned interpretation of the transfer agreement and had to be decided by the occupational pension court, not the supervisory authority.
Extrahierte Begründung
The controversy was a substantive dispute between two pension institutions about the content of the assumption agreement and who must bear the deficit. Such a question belongs to the judicial route under BVG rather than supervisory review.
