The claimant sought entitlement to the cost of an accounting report related to IRBs. Adjudicator Parish dismissed the dispute. She found that the delays which occurred with the file while the insurer was conducting an investigation regarding the accident did not establish that the accounting report was reasonable and necessary. Further, she found that the accounting report was commissioned prematurely at a time when there was no quantum dispute with respect to the IRB, and that the IRB calculation was straightforward based on two income sources and did not necessitate retaining an accountant.
