Key legal question
Whether the insured's cervical-brachial disorders qualify as an occupational disease under Art. 9 LAA.
Extracted holding
The disorders were not shown to have been caused exclusively or predominantly by the professional activity; the occupational disease claim fails.
Extracted reasoning
The medical expert attributed the complaints to severe degenerative cervical changes predating the work-related change in conditions. No epidemiological basis established the required qualified causation.
