Key legal question
Whether additional medical investigations were required for alleged jaw/sinus and headache complaints.
Extracted holding
No further investigations were necessary because the new medical statements were late, internally inconsistent, and not sufficiently probable to outweigh the existing record.
Extracted reasoning
The alleged complaints were not convincingly linked to the 2001 accident; the later medical opinion was based on the claimant's account, concerned a different anatomical problem, and post-dated the decisive administrative decision.
