AAI Limited v Ali [2015] NSWSC 1068

AAI Limited v Ali [2015] NSWSC 1068

The assessment was invalid because the medical assessor failed to consider and resolve central evidence concerning malingering, reliability, surveillance material and pre-existing impairment, and failed to expose the reasoning process required by the statutory assessment scheme. Those failures amounted to failure to consider relevant evidence and failure to give reasons under the Motor Accidents Compensation Act 1999. Because the s.63 review decision was based on the invalid assessment, it also had to be set aside as invalid.
