The insurer applied to the LAT seeking repayment of IRBs. The claimant did not participate in the hearing. Adjudicator Shapiro found that the claimant failed to advise the insurer that she started a new employment position shortly after the accident and that she received IRBs during the period of post-accident employment. Adjudicator Shapiro found that the overpayment of IRBs was made as a result of wilful misrepresentation, so the 12-month limitation on the request for repayment was not applicable, and the insurer was entitled to a repayment of IRBs plus interest.
