Kernrechtsfrage
Whether the IV decision was binding on the pension fund
Extrahierter Entscheid
The IV findings were not binding because the cantonal court plausibly found them manifestly untenable on the file.
Extrahierte Begründung
Binding effect exists only if the pension fund was involved, the issue was decisive, and the IV assessment is not clearly unsustainable overall. That threshold was not met.
