On December 26, 2016, the Plaintiff entered into a contract with the Defendants for advisory services or consulting services related to the Defendant Company’s LED business (hereinafter “instant contract”). Accordingly, the Plaintiff unilaterally terminated the instant contract despite the Defendants’ request for consultation and consulting services for about four months, thereby incurring damages equivalent to 50% of the sales revenue of the Defendant Company that could have been acquired by the Plaintiff and 3% of the amount when attracting investment money to the Defendant Company. Accordingly, the Defendants are jointly and severally liable to pay to the Plaintiff KRW 32,000,000 and damages for delay.

B. On the first preliminary basis, if the contract of this case was not entered into between the Plaintiff and the Defendants, the Defendants did not pay the corresponding amount of compensation even if they received advice, etc. from the Plaintiff on the Defendant Company’s business, and even if there was no remuneration agreement between the Plaintiff and the Defendants, the Plaintiff has the right to claim remuneration under Article 61 of the Commercial Act against the Defendants. Therefore, the Defendants are jointly and severally liable to pay to the Plaintiff the amount of unjust enrichment equivalent to the advisory fees or advisory fees, and delay damages therefor.
