Key legal question
Whether the claimant was entitled to an additional vested benefit of CHF 409,167 based on the early-retirement scheme
Extracted holding
No. The claimed early-retirement and bridging-rent expectations were based on collective labor agreements between the employer and the union, not on the pension fund regulations, so they did not generate a vested-benefit claim against the pension fund.
Extracted reasoning
The court held that the relevant agreements were labor-law arrangements binding the employer, not the pension institution. The pension fund never became a party to them, never incorporated them into its regulations, and never assumed the financing obligation on its own account.
