Purport of claim and appeal

1..

1. The reasoning for this case by the court of first instance is as stated in the reasoning of the judgment of the court of first instance, except for the following additional part, thereby citing this case as is in accordance with the main sentence of Article 420 of the Civil Procedure Act.

2. Additional determination

A. The Defendants asserted to the effect that they received an inheritance-limited approval decision by the Jung-gu Government District Court 2015Hun-Ma576 on June 15, 2015. As such, the Defendants’ obligations are inherent obligations with the network D and joint debtors, rather than the network D’s inheritance obligations. Therefore, this part of the Defendants’ assertion is without merit.

B. Defendant C alleged to the effect that he was a minor on August 9, 2009 at the time of the preparation of the cash tea certificate of this case, and thus, the above act of undertaking the obligation is revoked. Thus, the right to revoke shall be exercised within 10 years from the date when the juristic act is performed within 3 years from the date when it can be ratified. Article 146 of the Civil Code provides that “The right to revoke shall be exercised within 10 years from the date when the juristic act is performed within 3 years from the date when it becomes the adult who has become the adult who can be ratified by Defendant C.” As such, the above revocation claim is unlawful

Therefore, this part of the defendant C's assertion is without merit.

3. In conclusion, the judgment of the first instance court is justified, and the defendants' appeal is dismissed.
