Social security court dismisses claim for return of sick pay due to employer's failure to verify employment records.

The court dismissed the Social Insurance Institution's request for the return of sick pay, ruling that the claimant was not obligated to repay the benefit. The institution argued the claimant lacked insurance coverage because an employee was incorrectly added to employment records, creating a gap in voluntary coverage. However, the court held that the Social Insurance Institution failed its duty to conduct a thorough, substantive review of the submitted documents and cannot penalize the claimant for the institution's own administrative negligence.
