[2] Where an attorney-at-law brought a lawsuit seeking the payment of contingent fees pursuant to a delegation contract with Eul, the case holding that the obligation to pay contingent fees cannot be deemed as "business-related obligations" or "business office" referred to in the proviso of Article 467 (2) of the Civil Code, and that the obligation to pay contingent fees shall not be deemed as "business-related obligations" or "business office" referred to in the above provision, and that Eul's obligation to pay fees shall belong to the competent

2. However, in light of the various provisions of the Attorney-at-law Act which strictly limits attorney-at-law's profit-making activities and emphasizes high level of public nature and ethics with respect to their duties, an attorney-at-law's act of acting as an agent in connection with acts, etc. and legal affairs by using professional legal knowledge in accordance with the characteristics of each individual case based on an individual trust relationship with a delegating and commissioning person shall be punished, and an attorney-at-law's act of acting as an agent in connection with acts, etc. shall be punished by simple, prompt and external appearance; promoting business through free advertising and public relations activities; promoting the revitalization of business; and freely expanding the basis of personal and material business through the appointment of commercial employees, such as the establishment and manager of a place of business; and pursuing profits as much as possible through free expansion of the basis of business through an anonymous association, an anonymous association, and a commercial agent's act related to the attorney-at-law's duties and legal relations formed therefrom, and thus, it cannot be deemed that there is a special socioeconomic or demand that the Commercial Act should not apply.

Therefore, the obligation to pay contingent fees in this case cannot be deemed to be the "business obligation" or "business office" as referred to in the proviso of Article 467 (2) of the Civil Code, and the other party's performance obligation in this case is under the jurisdiction of the Seoul Eastern District Court, which is the competent court of the domicile of the re-appellant. Thus, the above judgment of the court below is erroneous in the misapprehension of legal principles as to the performance of obligation in Article 8 of the Civil Procedure Act.

3. Therefore, the order of the court below is reversed, but it is recognized that the case is sufficient to make a direct decision by the Supreme Court. As seen above, the lawsuit of this case is under the jurisdiction of the Seoul Eastern District Court, but it is obvious that the decision of the court of first instance transferred to the Jeju District Court without jurisdiction is unlawful. Thus, it is so decided as per Disposition by the assent of all participating Justices on the bench.
