In cases where any representative of a juridical person, or any agent, employee or other worker of a juridical person or individual has, in connection with the business affairs of the juridical person or individual, committed any violating act mentioned in the preceding two Articles, not only shall such violator be punished, but the juridical person or individual concerned shall be fined in accordance with the provisions of the respective Articles.
