A. The Defendant asserted that the Plaintiff had worked in the Plaintiff Company was paid KRW 77,962,710 in total as wages, retirement allowances, and bonus from February 2, 201 to September 201 without having worked in the Plaintiff Company.

The defendant is obligated to return the money from the plaintiff company as unjust enrichment because he received the money from the plaintiff company without any legal ground and suffered a loss equivalent to the same amount.

B. The burden of proving the fact that the general establishment requirement of unjust enrichment was made without any legal ground in a lawsuit claiming restitution of unjust enrichment is borne by the requester of return.

Therefore, in order to recognize that the defendant obtained unjust benefits equivalent to the withdrawn amount of this case as alleged by the plaintiff, the defendant must be proved to have acquired the above amount at will without any legal ground.
