Questione giuridica chiave
Whether the deceased's mother had to be joined as a party in the dispute over entitlement to LPP funds.
Decisione estratta
Yes. Her legal position is directly affected by the outcome, because the case will determine whether the husband has rights to the deceased wife's pension funds despite the testamentary designation of the mother as sole beneficiary.
Motivazione estratta
Because the judgment will directly affect the mother's legal sphere and her possible entitlement to the employer-share LPP assets, she must be called into the proceedings under the rules on joinder.
