Kernrechtsfrage
Whether the appellant could invoke good faith to require the pension fund to allow a CHF 31,062 capital withdrawal without reducing the retirement pension.
Extrahierter Entscheid
The 1996 letter concerned only housing-related early withdrawal under the then-applicable law and contained no enforceable assurance for a later retirement capital withdrawal; the elements of good-faith protection were not met.
Extrahierte Begründung
No specific promise or misleading assurance was given for the later capital option, which did not even exist in 1996; the appellant also did not show reliance through irreversible detriment.
