The insurer sought reconsideration of a decision in which the Tribunal found that the claimant had sustained a catastrophic impairment based on Criteria 7. The Tribunal concluded that the claimant had sustained 54% WPI. After rounding up, as permitted by the Guides, the claimant met the threshold of 55%. The insurer submitted that the Tribunal made errors of law and/or fact in assigning three of the WPI ratings (5% for the left leg disfigurement, 9% for the sleep disorder, and 3% for a discretionary increase). Adjudicator Grieves dismissed the insurer’s request for reconsideration, as the Tribunal carefully reviewed each sphere of possible impairment and provided sufficient explanations for accepting or rejecting evidence. She went on to note that while the insurer may disagree with the Tribunal’s assessment of the evidence, there was no basis to interfere with the decision.
