The claimant appealed the LAT’s decision that he did not suffer a catastrophic impairment. The claimant argued that procedural fairness was denied because he did not know the insurer would argue that an intervening event was the cause of his impairments, and argued that the LAT applied the wrong causation test. The LAT dismissed the appeal. Regarding procedural fairness, the Court held that the claimant’s failure to object to the insurer’s arguments at any point during the original hearing prevented him from advancing this argument on appeal. Failure to object deprived the Court of the evidence necessary to establish how the LAT would have dealt with the concern. Regarding causation, the Court held the LAT applied the proper “but for” test. The material contribution test is only applicable where there are multiple tortfeasors and there is risk of tortfeasors escaping liability by pointing the finger at one another. That was not the case in this dispute where the claimant suffered a medical event weeks after the accident.
