Kernrechtsfrage
Whether the claimant could obtain a child pension retroactively despite retiring before the statutory basis entered into force.
Extrahierter Entscheid
No. The claimant had no entitlement because he retired before the child-pension rule entered into force in CNA's statutes.
Extrahierte Begründung
Improper retroactivity is generally admissible in social insurance, but only if the legislator provides for it. Here, the statutory framework did not grant a retroactive right to a child pension for persons already retired before the new rule became effective.
