1. The part against the Defendant (Counterclaim Plaintiff) among the part against the principal claim in the judgment of the first instance shall be revoked, and the revoked part shall be revoked.

1. The reasoning of the judgment of this court is as follows, in addition to the determination of the defendant's assertion of violation of the Attorney-at-Law Act raised in the trial, not more than 6th of the judgment of the court of the first instance, and not more than 12th of the judgment of the court of the first instance is as stated in the judgment of the court of the first instance, and

3) The defendant asserts that the contract of this case is null and void in violation of Article 109 of the Attorney-at-Law Act, which is a mandatory law.

Article 109 subparag. 1 of the Attorney-at-Law Act provides that "any person, other than an attorney-at-law, who has received or promised to receive money, valuables, entertainment or other benefits, shall be punished by imprisonment with prison labor for not more than seven years or by a fine not exceeding 50 million won, with respect to cases of lawsuit, non-litigation, family conciliation or adjudication, administrative appeal or request for review or objection to an administrative agency, other cases of appeal against an administrative agency, and other cases of general legal affairs, etc.

"Other general legal cases" listed in subparagraph 1 of Article 109 of the Attorney-at-Law Act, which are prohibited from handling affairs of non-legal attorneys, refer to the general public in cases involving legal rights and duties, or the occurrence of new rights and duties relations. The term "other legal affairs" referred to in the same Article means dealing with matters that generate, alter, or extinguish legal effects and those that preserve or clarify legal effects (see, e.g., Supreme Court Decisions 96Do2340, Aug. 21, 1998; 2007Do1039, Feb. 28, 2008). The act of dealing with such legal affairs is sufficient if it is related to dealing with matters that generate, alter, extinguish, preserve, and clarify legal effects.
