2. Any part used in relation to the plaintiff's assertion and judgment on "the occurrence of liability for damages"

A. The part of the Plaintiff’s assertion regarding the crime of this case occurred during a short period of time through Internet banking. Nevertheless, in operating the Internet banking service, the Defendant failed to perform its duty of care as a good manager, such as neglecting to make efforts to prevent scams, such as the instant crime. (2) Moreover, the Plaintiff did not stipulate any content regarding termination through the Internet banking on the Defendant’s basic deposit transaction terms, home banking service user terms, electronic financial service terms, and electronic financial transaction basic terms and conditions, etc., which were applied at the time of the Plaintiff’s subscription to the housing purchase account and the Defendant’s subscription to the housing subscription deposit, which are the target deposit, and on the contrary, specified that the principal paid to the Defendant’s new account opened from the business place only exceeds KRW 30 million in the product description of the above target deposit prepared and delivered by the Defendant. Thus, it is possible to terminate only the Defendant’s subscription to the housing purchase account and the housing subscription deposit can not be terminated through the Internet banking even in the case of the Defendant’s new deposit subscription to the housing purchase account.
