Question juridique clé
Whether the employer had standing to sue for additional pension interest on former employees' retirement assets
Solution extraite
No. Standing belonged to the insured persons because the disputed surplus interest concerned their individual pension relationship, not the employer's contractual relationship with the pension fund.
Motifs extraits
The dispute concerned only the interest on the individual retirement assets and thus the legally regulated relationship between the pension fund and the former insured persons. It did not concern a matter governed by the affiliation agreement between the employer and the pension fund. The employer was therefore not the materially entitled party.
