Insurance court denied full disability pension due to insufficient medical evidence proving permanent work capacity loss.

The Insurance Court dismissed the applicant's claim for a full disability pension based on a work-related hearing disorder. The applicant, who had lost at least 60% of work capacity, argued for a permanent pension following a temporary period of incapacity from 1980 to 1984. The court rejected the request because the medical evidence failed to conclusively demonstrate that the work capacity loss was permanent and irreversible as required by law.
