Question juridique clé
Whether the cantonal social insurance court had to review the pension fund's complaint with full cognition rather than only for obvious error.
Solution extraite
The cantonal court had no basis to limit itself to reviewing only obvious factual or legal errors; it must decide the complaint again with full review of facts and law.
Motifs extraits
Art. 61 lit. c ATSG grants the cantonal social insurance court full cognition. The case-law on the binding effect of IV findings for later BVG proceedings does not justify restricting review in the IV appeal itself; that case-law only governs the binding effect between closed IV proceedings and subsequent BVG proceedings.
