The self-employed claimant and insurer disagreed about the quantum of IRBs; the claimant also sought interest on medical benefits approved shortly before the hearing, and a special award. Adjudicator Victor held that it was reasonable to base IRB calculations on the year prior’s gross business income as contemplated in s.4(3) of the SABS, and as such the claimant was entitled to IRBs based on the two income tax returns he provided within the stipulated timeframe. Adjudicator Victor held that requests for further and supporting information were excessive and that the claimant was only required to prove his self-employment income in accordance with the SABS. The claimant went further than required by providing an accounting report. There was a small period of non-compliance by the claimant for which the insurer was entitled to withhold IRB payments. Adjudicator Victor also held that an insurer being incorrect about the claimant not having proved the quantum of IRBs was not enough to grant a special award. Interest was awarded on the approved medical benefits.
