If the Board finds that at any time more than the correct amount of benefits has been paid to any individual under this Act or a payment has been made to an individual not entitled thereto (including payments made prior to July 1, 1940) recovery by adjustments in subsequent payments to which such individual is entitled under this Act or any other Act administered by the Board may, except as otherwise provided in this subsection, be made under regulations prescribed by the Board. If such individual dies before recovery is completed, recovery may be made by setoff or adjustments, under regulations prescribed by the Board, in subsequent payments due, under this Act or any other Act administered by the Board to the estate, designee, next of kin, legal representative, or surviving spouse of such individual, with respect to the employment of such individual.
Adjustments under this subsection may be made either by deductions from subsequent payments or, with respect to payments which are to be made during a lifetime or lifetimes, by subtracting the total amount of benefits paid in excess of the proper amount from the actuarial value, as determined by the Board, of such payments to be made during a lifetime or lifetimes and recertifying such payments on the basis of the reduced actuarial value. In the latter case recovery shall be deemed to have been completed upon such recertification.
There shall be no recovery in any case in which more than the correct amount of benefits has been paid to an individual or payment has been made to an individual not entitled thereto (including payments made prior to July 1, 1940) who, in the judgment of the Board, is without fault when, in the judgment of the Board, recovery would be contrary to the purpose of this Act or would be against equity or good conscience.
No certifying or disbursing officer shall be held liable for any amount certified or paid by him in good faith to any person where the recovery of such amount is waived under the third paragraph of this subsection or has been begun but cannot be completed under the first paragraph of this subsection.
If (i) benefits are paid to any employee with respect to unemployment or sickness in any registration period, and it is later determined that remuneration is payable to such employee with respect to any period which includes days in such registration period which had been determined to be days of unemployment or sickness, and (ii) the person or company from which such remuneration is payable has, before payment thereof, notice of the payment of benefits upon the basis of days of unemployment or sickness included in such period, the remuneration so payable shall not be reduced by reason of such benefits but the remuneration so payable, to the extent to which benefits were paid upon the basis of days which had been determined to be days of unemployment or sickness and which are included in the period for which such remuneration is payable, shall be held to be a special fund in trust for the Board. * * *
There shall not be considered as a day of unemployment or as a day of sickness, with respect to any employee- * * *
Benefits payable to an employee with respect to days of sickness shall be payable regardless of the liability of any person to pay damages for such infirmity. The Board shall be entitled to reimbursement from any sum or damages paid or payable to such employee or other person through suit, compromise, settlement, judgment, or otherwise on account of any liability (other than a liability under a health, sickness, accident, or similar insurance policy) based upon such infirmity, to the extent that it will have paid or will pay benefits for days of sickness resulting from such infirmity. Upon notice to the person against whom such right or claim exists or is asserted, the Board shall have a lien upon such right or claim, any judgment obtained thereunder, and any sum or damages paid under such right or claim, to the extent of the amount to which the Board is entitled by way of reimbursement.
