Kernrechtsfrage
Whether the waiver request concerned only the unrecovered balance of the repayment claim or the full refund claim of CHF 3,777.30.
Extrahierter Entscheid
The waiver request concerned the entire repayment claim, not merely the remaining balance after set-off.
Extrahierte Begründung
Set-off cannot deprive the insured person of the statutory possibility to seek waiver before the refund debt is finally determined; the lower court’s limitation to the residual amount was incorrect.
