The central issue in this dispute was the quantum of IRBs payable. The insurer sought repayment for IRBs in the amount of $6,535.62 due overpayment based on the claimant’s post-accident income. The dispute proceeded to an oral hearing. At the hearing, a timetable was set for written submissions. The claimant filed reply submissions 40 days past the deadline set at the hearing. The insurer sought to dismiss the claimant’s reply submissions from consideration. Adjudicator Truong allowed the reply submissions in the interest of natural justice and procedural fairness. Adjudicator Truong held that as the insurer was not entitled to respond to the claimant’s reply submissions, the insurer was not prejudiced by the claimant’s late submissions. As for the disputed quantum of IRBs, Adjudicator Truong held that the claimant’s collateral benefits disability plan, which provided payment for loss of income under an income continuation benefit plan, qualified as post-accident income and was deductible from the claimant’s IRB payment. Adjudicator Truong preferred the evidence of the insurer’s accountant and concluded that the insurer was entitled to repayment of $6,535.62.
