Questione giuridica chiave
Whether the IV office could offset the backpayment of A___'s child pension against the refund claim for the reduced child pensions of his siblings.
Decisione estratta
Yes. The offset was lawful because the claims were sufficiently closely connected and arose within the same family pension context; the appealer's argument that the debtor and creditor were different persons did not prevent set-off.
Motivazione estratta
IV pensions may be set off against claims under the IVG/AHV framework. The child pension is an addition to the mother's main disability pension, and the backpayment for the appellant and the refund arising from the retroactive reduction of the other child pensions are closely linked. The court held that this connection would even allow set-off between different persons, and a fortiori between child pensions attached to the same main pension.
