1. The plaintiff's primary claim against the defendants is dismissed in entirety.

2.(a)

Defendant D Co., Ltd., Ltd., and the Plaintiff A.

1. Judgment on the main claim

A. The summary of the Plaintiff’s assertion is both Defendant D Co., Ltd., Defendant E Co., Ltd., and Defendant F Co., Ltd. (hereinafter, in the case of a party to a contract, the name of the corporation is omitted) and are engaged in activities as a separate legal entity for the purpose of saving taxes and allocating debts to the same company that operates “G” brand chain.

Therefore, the defendants are jointly and severally liable to pay the price for each product to the plaintiffs, such as the primary purport of the claim.

B. The result of the order to submit each taxation information on Gap evidence Nos. 1-2, 3, and 4 and Gap evidence Nos. 2-4, 5, 6, and 2-4, 5, 6, and Mali Tax Office and Gangwon Tax Office is insufficient to recognize that the defendants' corporate form has been damaged and the same company is substantially identical, and there is no other evidence to acknowledge otherwise.

Therefore, the plaintiffs' primary claims are without merit.
