The claimant applied to the LAT seeking entitlement to benefits, including a CAT assessment, after being involved in a motor vehicle accident. Vice-Chair Shapiro found that the claimant failed to establish on the evidence that a CAT assessment would be both reasonable and necessary in the circumstances, highlighting that the threshold requires the claimant to demonstrate that her impairments warrant investigation that she possibility has a CAT impairment. Specifically, as the claimant was alleging mental and behaviour impairments, she would need to a show Class 4 marked impairments. The claimant relied largely on her own self-reports which the Tribunal found to be contradictory and inconsistent, including in relation to her injuries, her medical functionality, her symptoms, and her work history. Two further treatment plans for an attendant care assessment and chiropractic services were also dismissed as not reasonable and necessary.
