2. Additional determination

A. The Defendant’s assertion expressed to the Plaintiff that the Defendant requested the Plaintiff to pay the electricity fee under the name of the Codefendant C Co., Ltd. of the first instance trial (hereinafter “C”), which is the actual user. Accordingly, the Plaintiff urged the Plaintiff to pay the unpaid electricity fee, and requested the Plaintiff to implement the procedure for change of the name of the contract for electricity use. C paid part of the unpaid electricity fee to the Plaintiff and expressed his intention to pay the unpaid electricity fee in full. After receiving the Defendant’s above request, the Plaintiff sent the notice of the electricity fee to C without sending the notice of the electricity fee to the Defendant, and then sent the customer name C.

B. In light of the following circumstances, it is difficult to view the Plaintiff’s claim of this case contravenes the principle of good faith or the principle of notions solely on the sole basis of the Defendant’s assertion, and evidence to acknowledge otherwise.
