Question juridique clé
Whether the pension fund regulation change violated the equality principle by granting supplementary vested benefits only to active insured persons after 1 February 1999.
Solution extraite
No. The distinction was justified because the supplement compensated the reduction in vested benefits caused by the lower actuarial current values and preserved acquired protection for active members.
Motifs extraits
The court held that equal treatment under Art. 8 Cst. is breached only if similar situations are treated differently without reasonable grounds. Here, active members and already retired persons were not in the same position after the new regulation entered into force, because the supplement offset a loss in vested benefits linked to the new actuarial table.
