(a) A corporation, association, firm, partnership, or limited partnership is liable for the acts of its officers, directors, representatives, or agents acting within the scope of their authority. Proof of the acts of any officer, director, representative, or agent shall be received as prima facie proof of the acts of the corporation, association, firm, partnership, or limited partnership itself.
(b) When a corporation, association, firm, partnership, or limited partnership violates this chapter, the violation shall be deemed to be that of the individual directors, members, officers, managers, employees, or agents of the corporation, association, firm, partnership, or limited partnership who knowingly authorized, ordered, aided, abetted, or advised in the acts or omissions constituting in whole or in part the violation, whether the individuals acted on their own behalf and for their own benefit, or for the corporation, association, firm, partnership, or limited partnership and in their representative capacity. The individuals, in their capacity as individuals, are subject to the provisions of this chapter and may be joined, if subject to personal jurisdiction, as additional parties defendant in the proceedings against the corporation, association, partnership, or limited partnership.
