Questione giuridica chiave
Whether the old pension regulations remained applicable after the transfer of affiliation and collective insurance.
Decisione estratta
The old regulation did not remain fully applicable; the new institution could apply its own regulation, subject to mandatory minimum LPP limits and any acquired rights actually guaranteed.
Motivazione estratta
The court distinguished cases where rentiers are covered by a collective insurance contract linked to the affiliation contract. On transfer, the earlier contract ended and the rentier moved to the new fund; absent a valid reservation or guaranteed acquired rights, the new regulation governed the calculation of benefits.
