Purport of claim and appeal

The key issue of the instant case is whether the Defendant’s joint and several surety agreement was reached according to the Defendant’s will, and the reasons why the court stated in this case are as follows: “Defendant C shall grant an authorized certificate with respect to Defendant A’s indemnity liability under the instant guarantee insurance contract” in the fourth-third part of the lower judgment at the fourth-third part of the judgment of the first instance, except that Defendant C shall state the reasoning of the first instance judgment on October 31, 2013 as “an authorized certificate with respect to Defendant A’s indemnity liability under the instant guarantee insurance contract,” and therefore, it is identical to the part of the first instance judgment’s reasoning.

Therefore, the judgment of the first instance court is justifiable, and the defendant's appeal is dismissed as it is so decided as per Disposition.
