Kernrechtsfrage
Whether the cantonal social insurance court had subject-matter jurisdiction over the Security Fund's Art. 56a BVG recourse action against the bank.
Extrahierter Entscheid
Yes. The claim is based on Art. 56a BVG, and the broad circle of potentially liable persons includes a bank managing pension assets; jurisdiction is determined by the pleaded claim and the facts relevant to both admissibility and merits are to be assessed at the merits stage.
Extrahierte Begründung
For Art. 56a BVG claims, the court must look to the asserted recourse claim, not to a restrictive pre-assessment of culpability or passivlegitimation. Double-relevant facts are generally not decided at the admissibility stage; the cantonal court improperly resolved substantive issues when refusing jurisdiction.
