2. Determination

A. According to the above facts of recognition as to the cause of the claim, the defendant is obligated to pay to the plaintiff 10,768,401 won for joint and several sureties debt amounting to 10,768,401 won and 8,99,969 won among them, 19% per annum from March 10, 2008 to August 22, 2008 and 20% per annum from the next day to the date of full payment.

B. The Defendant asserted that the Defendant signed the loan transaction agreement as a joint and several surety and did not jointly and severally guarantee C’s above loan obligations against the Plaintiff.

On the other hand, since a final and conclusive favorable judgment has res judicata effect, the parties can not file a new suit on the basis of the same subject matter of lawsuit as the final and conclusive judgment, in principle, and in exceptional circumstances such as the interruption of extinctive prescription, a new suit is exceptionally allowed. In such a case, the judgment of a new suit does not conflict with the final and conclusive judgment in favor of the previous suit, and thus, the court of the subsequent suit can claim the established right.
