In light of the records, the judgment of the court below is just and acceptable, and contrary to the allegations in the grounds of appeal, there are no errors of violating the law of logic and experience and free evaluation of evidence.

2. Article 50 (6) of the Attorney-at-Law Act provides that "An attorney-at-law in charge of a law firm shall represent the law firm in the course of performing the designated affairs." Article 210 of the Commercial Act, which applies mutatis mutandis under Article 58 (1) of the Attorney-at-law Act, provides that "Where a member representing a company has inflicted damage on another person in the course of performing his/her duties, the company shall be jointly and severally liable with such member."

The appeal by Defendant Seo-gu is dismissed, and the costs of appeal by Defendant Law Firm Seo-gu are assessed against the losing party. It is so decided as per Disposition by the assent of all participating Justices on the bench.
