Kernrechtsfrage
Whether the cantonal decision on prepayment duty under Art. 26(4) BVG was a final, appealable decision and not merely an interim measure.
Extrahierter Entscheid
The decision is a final decision and may be appealed independently.
Extrahierte Begründung
Prepayment duty does not end with the main proceedings and can exist independently of them; it regulates a legal relationship with possible lasting effect and therefore qualifies as a final decision.
