The Spouses Steiner entered into a contract with Acme Group Inc. (AGI), a construction company, to design and construct a 5 storey commercial/residential building for a piece of 15 million in accordance with the specifications attached to the constructions contract. The president of AGI was jan giri. Giri materially revised and deviated from the specifications and structural plan of the building in order to reduce costs without notice to or approval of the spouses steiner. The spouses steiner filed a complaint for damages against AGI and Jan giri before the contruction industry Arbitration commission, which rendered a decision holding giri jointly and severally liable with AGI for damages to the spouses stenier. On appeal to the court of appeals, Giri argued that he cannot be jointly and severally held liable with AGI as it would violate the doctrine of seperate juridical personality of corporation. Is Giri's argument correct? Explain.
