Question juridique clé
Whether the cantonal social insurance court had jurisdiction under Art. 73 BVG over the claimed share of an individualized early-retirement reserve
Solution extraite
Yes. The claimant pleaded a pension-law claim arising from the pension relationship; any doubly relevant facts had to be examined on the merits, not at the admissibility stage.
Motifs extraits
Jurisdiction depends on the claim as pleaded. The action concerned an asserted occupational pension entitlement, not merely an issue for the supervisory authority. Because the legal basis and factual characterization were intertwined, the court had to enter into the merits.
