The claimant sought entitlement to a TMJ assessment. The insurer argued that the Tribunal had already determined whether the claimant suffered TMJ injuries in the accident during an earlier proceeding. Adjudicator Grant agreed with the insurer that the causation of the claimant’s TMJ symptoms had already been addressed by the Tribunal, and that res judicata barred the claimant from re-litigating the issue. He also held it would be an abuse of process for the Tribunal to make a determination contrary to the Tribunal’s earlier decision.
