Whether Art. 37(2) BVG grants a right to partial capital withdrawal from the mandatory occupational pension when a disability pension later converts into an old-age pension.
No. Art. 37(2) BVG applies only to mandatory old-age assets and not to disability pensions or to the extra-mandatory area.
The provision is a minimum rule under the mandatory scheme and contains no reference extending it to over-mandatory benefits. A later conversion from disability pension to old-age pension does not change that the entitlement arises only under the regulations if they provide it.
