Questione giuridica chiave
Whether the AHV old-age pension must be included in the BVV2 overcompensation calculation.
Decisione estratta
No. An AHV old-age pension is not a benefit of the same type and purpose under Art. 24 Abs. 2 BVV2 because it is paid due to age, not due to the injurious event.
Motivazione estratta
The wording of Art. 24 BVV2 requires event-related congruence. Systematic and historical interpretation do not justify including AHV old-age pensions; the purpose of avoiding overcompensation cannot override the clear text.
