The claimant appealed the Tribunal’s decision that he did not suffer a catastrophic impairment due to a GCS score less than 9. The primary grounds for appeal were the Tribunal’s refusal to admit video evidence of the accident and treatment by EMS, and the Tribunal’s decision to allow an IE expert to comment on matters outside of the written report. The Court held that the Tribunal breached the claimant’s right to procedural fairness on both grounds. First, the Tribunal ought to have allowed the video evidence to be submitted as it was relevant and could be probative of the claimant’s GCS score immediately after the accident. Second, the Tribunal ought to have allowed the claimant relief after the IE expert gave opinion evidence not contained in his written report. The Tribunal could have adjourned for a short period to allow counsel to prepare for cross-examination. The Tribunal also could have allowed the claimant to recall his own expert to give reply evidence. The Tribunal’s refusal to allow either was procedurally unfair to the claimant because it denied him an equal opportunity to address the new evidence. The matter was returned to the Tribunal for a new hearing before a new adjudicator.
