[Reasons for Recognition] Unsatisfy, Gap evidence 1 through 9 (including branch numbers for those with additional numbers; hereinafter the same shall apply), Eul evidence 3 and 5, the purport of the whole pleadings

2. Determination as to the cause of action

A. Regarding claim for contract performance guarantee

In the event that the instant subcontract was terminated due to the nonperformance of contractual obligation under the contract between the Plaintiff, Jungan Industrial Development, and Jungan Industrial Development, the contract performance guarantee money is agreed to vest in the Plaintiff and Jungan Industrial Development; the development of the light-sea industry was concluded with the Defendant as the guarantee creditor; the Plaintiff concluded the instant performance guarantee contract with the Plaintiff on October 20, 201; and the fixed industry was terminated on December 14, 201 on the ground that the cause attributable to the development of the marine industry was attributable to the surrounding around December 14, 2011. Accordingly, the Defendant, the guarantee creditor of the instant performance guarantee contract, is obligated to pay the Plaintiff the contract performance guarantee money of KRW 43,136,922 and the delay damages corresponding to the Plaintiff’s share in the contract performance guarantee money of KRW 84,582,200.

B. As to the claim for advance payment deposit

The facts are as follows: (a) the Plaintiff entered into the instant advance payment guarantee contract with the Defendant as the guarantee creditor; (b) the Plaintiff paid KRW 153,841,500 to the Plaintiff around April 2010; and (c) the Plaintiff and the Plaintiff agreed to deduct the construction cost equivalent to a total of KRW 94,028,377 out of the subcontract price of this case from the said advance payment; (d) the advance payment that has not been settled between the Plaintiff and the Plaintiff is KRW 59,813,123 (153,841,50 - 94,028,377). Accordingly, the Defendant is obligated to pay the Plaintiff the balance of the advance payment, KRW 59,813,123,123 (153,841,500 - 94,028,377).

C. Sub-committee

Ultimately, the Defendant is obligated to pay to the Plaintiff the amount of KRW 102,950,045 (the contract deposit KRW 43,136,922 + advance payment deposit KRW 59,813,123) and damages for delay calculated at each rate of 15% per annum under the Commercial Act from October 21, 201, which is the date of termination of the instant subcontract until May 12, 2017, which is the date of the first instance judgment that the Plaintiff seeks, and from the next day to the date of full payment, from the next day to the date of full payment.

3. Determination on the assertion of extinctive prescription

A. The parties' assertion

1) The defendant's assertion

On October 20, 201, when the instant subcontract was terminated, the period of extinctive prescription expired on October 20, 201, and five years from October 20, 201. Accordingly, both the contractual performance guarantee and the obligation to pay advance payment, which are the guaranteed obligation owed by the Defendant to the Plaintiff, were extinguished in accordance with the principle of subsidiaryness of the guaranteed obligation.

2) The plaintiff's assertion

In a lawsuit seeking confirmation of the existence of a prior obligation that the Defendant filed against the Plaintiff, the Plaintiff participated in the lawsuit seeking confirmation of the existence of a prior obligation, and actively asserted that the Plaintiff did not have any contractual performance bond and advance payment return claim for the development of the Maritime Industry. Accordingly, the Plaintiff actively reflected in the claims for the development of the Maritime Industry, and accepted such claims and won the lawsuit in the above lawsuit. This ought to be deemed to be the same as the Plaintiff’s winning the lawsuit. As such, the statute of limitations on the Plaintiff’s contractual performance bond and advance payment claim for the development of the Maritime Industry was interrupted. Accordingly, the Defendant’s obligation to pay the instant contract performance bond and advance payment deposit against the Plaintiff, which constitutes the guaranteed obligation, is not extinguished in accordance with the principle of non-performance of the guaranteed obligation.

B. Determination

1) In general, a judicial claim under Article 168 subparag. 1 and Article 170(1) of the Civil Act refers to cases where a right holder claims prescription as the plaintiff as the defendant in the form of a lawsuit. However, as to the plaintiff's filing of a lawsuit, it is reasonable to interpret that the same includes a case where a person who claims prescription as the defendant has responded to the lawsuit by the defendant and actively claims the right in the lawsuit and has accepted the lawsuit. The period of prescription is a system established to deny the protection of the person above the right and to give a certain legal effect by respecting the fact that it is common in social life, and it is no longer possible to respect such fact while the above situation remains in existence, and thus, the purport of recognizing the interruption of prescription is to recognize the interruption of prescription immediately in order to lose the effect of the period of prescription, considering that there is no reason to respect the situation of the fact, and as such, it cannot be viewed that the right holder does not go against the right of the other party's filing of a lawsuit directly from the person who asserts prescription, and it does not go against one another person's right.

2) According to the evidence revealed earlier, on April 15, 2013, the Defendant filed a lawsuit seeking confirmation of non-existence of the guaranteed obligation against the Plaintiff under each of the instant guarantee contracts against the Plaintiff. The Plaintiff responded to the Defendant’s claim on June 17, 2013 by submitting a written response, etc. and actively asserted the existence of the guaranteed obligation under each of the instant respective guarantee contracts. The Defendant’s development of the ordinary sea industry, which is the primary debtor of each of the instant guaranteed obligation, participated in the instant lawsuit for the Defendant on August 12, 2013 where the lawsuit seeking confirmation of non-existence of the guaranteed obligation against the Plaintiff was pending in the first instance court, and the instant subcontract was terminated due to the Plaintiff’s failure to pay advance payment, or the Plaintiff did not have asserted that there was no contractual obligation and refund of advance payment obligation against the Plaintiff of the industrial development guaranteed under each of the instant respective guaranteed obligation under each of the instant respective guarantee contracts, and the Plaintiff presented a written reply to the lower court’s judgment regarding the Plaintiff’s respective principal obligation and the instant advance payment claim 2010.

3) According to the above facts, the defendant's lawsuit seeking confirmation of the existence of the principal obligation against the plaintiff was mainly at issue, rather than whether the defendant's guarantee obligation under each contract of this case exists, and the existence of the obligation to pay the contract deposit and the obligation to return advance payment against the plaintiff of the light marine industry development, which is the principal obligation. After participating in the lawsuit for confirmation of the existence of the principal obligation, it is sufficient to view that the plaintiff's assertion that there was no principal obligation on the ground that the subcontract of this case was terminated due to the plaintiff's fault or the plaintiff paid advance payment. Accordingly, since the plaintiff actively disputed the existence of the principal obligation of the light marine industry development, the plaintiff's assertion that the principal obligation of the light marine industry development exists, as well as the defendant's right to develop the light marine industry, it is sufficient to view that the plaintiff is not a locked person on the above right by asserting that the right of the former marine industry development as well as the defendant did not exist. Accordingly, in the lawsuit seeking confirmation of the existence of the principal obligation, the plaintiff's above response act constitutes a cause for interruption of extinctive prescription (see Supreme Court Decision 2014.2014.

4. Determination as to the defendant's application for return of provisional payments

On May 16, 2017, the Defendant asserted that the Plaintiff paid KRW 137,456,644 to the Plaintiff based on the judgment rendered by the provisional execution sentence of the first instance court on May 16, 2017, which was subsequent to the pronouncement of the first instance judgment, and sought payment of KRW 137,456,64 as the return of the provisional payment, on the premise that the judgment of the first instance is revoked. However, as seen above, the judgment of the first instance is justifiable, and thus, the Defendant’s application for the return of the provisional payment premised on the revocation

5. Conclusion

Therefore, the plaintiff's claim of this case shall be accepted on the grounds of its reasoning. Since the judgment of the court of first instance is just in conclusion, the defendant's appeal and the request for return of provisional payment are dismissed on the grounds of its merit. It is so decided as per Disposition.
