Questione giuridica chiave
Whether the 1993 internal IV commission decision created enforceable pension rights despite never being formally served.
Decisione estratta
It created no legal effect because the decision was never duly served; non-notified administrative decisions are ineffective.
Motivazione estratta
Service is constitutive for validity. Since the claimant had no address and no representative, publication was possible but not mandatory; without publication, no decision was ever opened and thus no legal effects arose.
