Kernrechtsfrage
Whether the hardship waiver must be assessed under pre-LPGA jurisprudence or under Art. 25 LPGA / Art. 5 OPGA
Extrahierter Entscheid
The transitional rules do not exclude application of the LPGA here; the hardship assessment is governed by Art. 25 LPGA and Art. 5 OPGA, while prior case law on retroactive lump-sum AI payments remains relevant.
Extrahierte Begründung
The repayment claim was not definitively fixed before the LPGA entered into force. Legislative history showed no intent to abandon the earlier rule; the old and new regimes largely correspond, so earlier case law is maintained.
