The claimant applied to the LAT seeking IRBs following her 2015 accident. She had returned to work after the accident, and the insurer denied entitlement to IRBs. After the 104 week mark, the claimant stopped working and submitted an Election to the insurer claiming IRBs. The insurer again denied IRBs, arguing that IRBs had been denied four years prior and the claimant failed to establish entitlement to IRBs within the first 104 weeks. Notably, the claimant was deemed to have suffered a catastrophic impairment as a result of the accident in 2019. Adjudicator Boyce found that the limitation period applied to the IRB claim, and the claimant failed to establish IRB eligibility because she did not suffer a substantial inability within the first 104 weeks after the accident, regardless of her deteriorating condition after the 104 week mark. He rejected the claimant’s argument that Tomec would create a new date of discoverability for the IRB claim.
