The insurer sought repayment of $9,673.38 in IRBs and accountant fees of $2,353.93. Adjudicator Ferguson concluded there was an overpayment of IRBs because the claimant had misrepresented his pre-accident income and that the insurer’s payment of IRBs was therefore made in error. He held that he had no jurisdiction to order the claimant to reimburse the insurer for the cost of the accounting costs.
