The insurer sought repayment of IRBs due to the claimant’s return to work, which he failed to report for six months. The claimant and the insurer initial agreed to a repayment plan of $200 per month, but the claimant ceased payment eventually. The insurer sent a new repayment request for the remaining overpayment. Adjudicator Boyce agreed that the claimant committed a wilful misrepresentation due to his failure to report his return to work, and that the insurer was entitled to repayment of the remaining overpayment. He also found the insurer entitled to interest on the repayment request from the date of the LAT application.
