Purport of claim and appeal

1..

1. The reasoning for the court’s explanation of this case is as follows, except where the defendant added or emphasized the argument that the court added or emphasized to this case, and as such, the reasoning for the judgment of the court of first instance is as stated in the main sentence of Article 420 of the Civil Procedure Act.

2. The Defendant asserts that, upon the conclusion of the joint and several guarantee agreement of this case, the Defendant voluntarily supplemented the guarantee period that the Plaintiff had to include the overdue period, as the trade name of the company was changed to B and the electric utility fee began to be overdue. The Defendant asserts that, at the time of the conclusion of the joint and several guarantee agreement of this case, the Defendant voluntarily supplemented the guarantee period to include the overdue period.

However, according to the evidence No. 8, the fact that the name of the consumer of electricity was changed from the defendant who is an individual to E on July 14, 2016 can be acknowledged. Thus, the electricity charge liability of the E Co., Ltd., which is the principal obligation of the joint and several surety agreement of this case, began on July 14, 2016.

As a result, this part of the defendant's assertion was concluded first for at least two years even if the principal obligation was commenced, and thus, it cannot be accepted.

3. In conclusion, the judgment of the court of first instance is legitimate, and the defendant's appeal is dismissed as it is without merit. It is so decided as per Disposition.
