Questione giuridica chiave
Whether the cantonal court violated the appellant's right to be heard by deciding after remittal without a further exchange of briefs
Decisione estratta
No. The remittal did not create a new decision basis requiring a further hearing because the liability claim under Art. 52 BVG had already been fully debated and the underlying legal basis remained the same.
Motivazione estratta
The parties had already addressed the prerequisites of liability in the prior written proceedings. The federal remittal only clarified that the pension fund was an unregistered occupational pension foundation subject to Art. 52 BVG; this did not alter the factual or legal framework of the claim.
