Questione giuridica chiave
Whether the lumbar complaints were causally attributable to the accident under accident insurance law.
Decisione estratta
The fluctuating lumbar pain had to be attributed to pre-existing conditions; the accident was not shown to have caused a lasting health impairment.
Motivazione estratta
The mere existence of pain is insufficient to prove natural causation or a durable accident-related injury. In the circumstances, the insurer could rely on the medical evidence and the status quo sine.
