The judgment below is reversed, and the case is remanded to Seoul Southern District Court Panel Division.
We examine the grounds of appeal.
1. Regarding ground of appeal No. 1
The court below rejected the defendants' assertion that "The monetary transaction between the plaintiff and the defendant 1" provided money to the defendant 1 as a means of inducing and coercing the plaintiff to engage in sexual traffic against the customers at the above main point, and thus the plaintiff's claim against the defendant 1 arising from the above monetary transaction against the defendant 1 is null and void because it violates good morals and other social order. Thus, the money that the plaintiff provided to the defendant 1 constitutes illegal consideration and thus it cannot be claimed as return by the plaintiff, and the guarantee agreement between the plaintiff and the defendant 2 is null and void." In light of the records, the above judgment of the court below is just and there is no violation of the rules of evidence, as
2. Regarding ground of appeal No. 2

(b) Applicable law;
In this case where the plaintiff of Korean nationality and defendant 1 concluded a labor contract with the contents of labor provision in Japan's main office located in Japan, and the invalidity of the contract of this case that is the contents of the labor contract constitutes a legal relationship with foreign elements, the applicable law should be first determined. Since this case is a matter arising prior to the enforcement of the Private International Act which was revised by Act No. 6465 of April 17, 2001 and enforced from July 1, 2001, the applicable law should be determined by the former Conflict of Laws Act.
Article 9 of the former Conflict of Laws provides that the law shall be applied to the establishment and validity of a juristic act by the parties' intent, and when the parties' intent is not clear, the law shall be applied to the place of the act. In the absence of an express agreement between the parties on the choice of the governing law, the parties' implied intent shall be presumed based on the contents of declaration of intent other than the governing law included in a labor contract, the attitude of the parties expressed through the litigation, etc. In the absence of such implied intent, even if such implied intent cannot be presumed, the parties' nationality, domicile, etc., the place of living, including the parties' nationality, domicile, the governing law of the juristic person which is the employer, the governing law of the establishment of the juristic person, the place of labor payment, and the contents of the labor contract, shall be presumed to have been selected by the parties at the time of the labor contract (see Supreme Court Decision 2002Da56130, 56147, June 25, 2004)
In light of the above legal principles, in this case where there is no express provision on the governing law in the labor contract between the Plaintiff and Defendant 1, the Plaintiff and Defendant 1 both have Korean nationality, but considering that the labor contract was concluded in Japan, the workplace where the labor contract was provided is located in Japan, and the parties’ reasonable intent, it is reasonable to view that the governing law on the validity of the labor contract between the Plaintiff and Defendant 1 is a Japanese law.
C. Effect of the instant agreement
Article 16 of the Labor Standards Act of Japan provides that "An employer shall not determine a penalty for non-performance of a labor contract or conclude a contract which provides for liquidated damages." The purport of this Act is that if an employee pays a penalty or damages even if he/she did not receive any consideration in the event that he/she did not perform a labor contract, he/she shall not escape from the detention of the labor contract even if he/she entered into an unfavorable labor contract. Thus, by prohibiting the above agreement on liquidated damages or liquidated damages, the employee shall be prevented from being forced to continue his/her work under the restriction on the freedom of retirement, guaranteeing the freedom of workers at the time of entering into a labor contract, and protecting the termination of an unfavorable labor contract. Therefore, the agreement in violation of Article 16 of the above Labor Standards Act shall be deemed null and void. Thus, the agreement in this case shall be deemed null and void, after deducting a fixed agreed amount from monthly wages in cases where Defendant 1 did not perform his/her duties, and if Defendant 1’s customer did not pay the credit payment obligation on behalf of the employer, it constitutes actual invalidity of the penalty or liquidated damages.
D. Whether the Defendants’ obligations against the Plaintiff exist
According to the records, the plaintiff is aware that the sum of the sum of Defendant 1's monthly salary deduction or the sum of the amounts included in Defendant 1's debt 2,295,000 UN on credit for customers, fines of 1,069,000 UN on absence, fines of 1,129,000N on absence, and fines of 1,73,000 UN on the part of non-performance of accompanying obligation is 4,73,000 UN. As long as the agreement of this case is null and void, the above sum should be deemed to have been appropriated for Defendant 1's repayment of debt to the plaintiff. As seen above, on the premise that the agreement of this case is valid on June 13, 200, the above sum should be deemed to have been extinguished by the agreement of this case on June 13, 20, and the amount of debt 200,000 UN on June 13, 200.
Therefore, the claims against the Defendants asserted by the Plaintiff were extinguished or nonexistent. The court below did not determine the Defendants’ assertion that the agreement in this case is null and void, but accepted all of the Plaintiff’s claims in this case on June 13, 2000 on the ground that the agreement in this case and Defendant 1’s expression of intent to bear the obligation on June 13, 2000 were valid. The court below erred in the misapprehension of legal principles as to the validity of the agreement as to penalty for breach of labor contract or liquidated damages for breach of labor contract, and in omission of judgment as to the Defendants’ above assertion, thereby affecting the conclusion of the judgment. The
Therefore, without further proceeding to decide on the remaining grounds of appeal, the judgment of the court below is reversed, and the case is remanded to the court below for a new trial and determination. It is so decided as per Disposition by the assent of all participating Justices.
