⚖️ What tends to weigh in cases like this
✅ Tends to be accepted
- The Medical Assessor made an error of law by applying the wrong test for causation, treating the claimant's operation as wholly related to a pre-existing condition.
- The motor vehicle accident does not have to be the sole or major cause of injury, only a contributing cause that is more than negligible.
- The Authority made an error of law by misinterpreting "additional relevant information about the injury" when refusing a further medical assessment.
- New medical opinions about the cause of injury, not previously considered, qualify as "additional relevant information about the injury".
- The Assessor's statement of reasons contained ambiguities and inconsistencies crucial to the case's resolution.
❌ Tends to be rejected
- The argument that the Assessor's error was merely an error of fact was rejected, as it was a misunderstanding of the causation test.
- The argument that the pre-existing condition's clinical significance was the test for causation was rejected.
