The insurer appealed the Tribunal’s decision that the claimant was entitled to IRBs during a period of section 33 non-compliance. The Tribunal found that the claimant’s explanation for the delay in providing records was reasonable because she thought the insurer had access to her medical records by way of signed authorization, and that she was suffering from post-traumatic stress. The insurer argued that the Tribunal erred by applying subjective factors to the reasonable explanation. The Court dismissed the appeal, holding that the reasonable explanation under section 33 was not a strictly objective test, and that the reasonableness of the explanation had to be considered in the context of the particular claimant and take into account the remedial nature of the SABS.
