1. Determination as to the cause of claim

A. 1) The Plaintiffs asserted to the network D, the Plaintiff A lent KRW 20,000,00 on October 14, 2008, KRW 15,000,000 on December 26, 2005, KRW 20,000 on October 2, 2011, KRW 3,000,000 on October 31, 201, and KRW 20,000,000 on October 31, 201, respectively. 2) the Plaintiff died on May 3, 2014, and the heir was the Defendant, E, and F, but the Plaintiff succeeded to D solely by giving up inheritance.

3. Therefore, the defendant is obligated to pay each of the above loans and damages for delay to the plaintiffs.

B. Comprehensively taking account of the overall purport of the arguments in each statement in subparagraphs 4 and 6, Plaintiff A wired KRW 30,000,000 to D on October 14, 2008, Plaintiff B transferred KRW 15,000 on December 16, 2005, KRW 2,000,000 on October 12, 201, and KRW 3,000,000 on October 31, 201, respectively.

However, each of the above facts alone is difficult to recognize that the plaintiffs lent the above money to D, and there is no other evidence to acknowledge it.

Therefore, the plaintiffs' above assertion based on this premise is without merit without further review.

2. It is so decided as per Disposition by the assent of all participating Justices on the grounds that the plaintiffs' claims are without merit.
