Questão jurídica principal
Whether the cantonal social insurance court had jurisdiction over the asserted claim under Art. 73 BVG.
Decisão extraída
The court could only be competent if the claim was a BVG contribution claim; a loan claim would fall outside Art. 73 BVG.
Fundamentação extraída
Art. 73 BVG covers disputes directly linked to occupational pension relations, especially contribution claims. A loan relationship is pension-external and therefore not subject to that jurisdiction.
