“On the other hand, the Plaintiff’s answer submitted by the Defendant to the first instance court on October 11, 2017 (hereinafter “instant reply”).

(1) Article 274(1) of the Civil Procedure Act provides that the party or his/her agent should affix his/her name and seal to the petition of appeal, even if the appellant’s name and seal are omitted, the appellant may be identified by the statement, and if it is deemed that it was submitted based on his/her appellant’s intention, it cannot be deemed null and void (see, e.g., Supreme Court Decision 2010Da84956, May 13, 201). In light of the aforementioned legal principles, it is reasonable to view that the respondent’s signature and seal is irrelevant to the validity of the written reply, and whether the Defendant’s seal is affixed to the written reply, and that the Defendant’s signature and seal is not written in the written reply, in light of the fact that the Defendant’s signature and seal is written in the written reply, and that the Defendant’s written reply is not written in accordance with the Defendant’s written reply.

Therefore, the plaintiff's assertion that it is impossible to recognize the validity of the reply is accepted.
