Employer failure to report work in special conditions implies such work was not actually performed.

The court dismissed the claim regarding social insurance for work in special conditions due to the employer's failure to file a report. The plaintiff argued that the lack of notification implied the work was never performed, while the defendant contended the absence of a report did not negate the factual occurrence of the work. The court ruled that the procedural omission did not automatically establish the non-existence of the work, thereby rejecting the plaintiff's inference.
