The development of the Plaintiff’s dispatching industry was affixed along with the Plaintiff’s Sejong, and even at various places in the terms of the contract, the Plaintiff’s “Buyer” in the last Chapter is clearly indicated as the purchaser.

Therefore, the plaintiffs are bound to conclude the sales contract of this case with the defendants as joint buyers.

Moreover, the Defendants’ “B” was drafted as of May 18, 2006, prior to the conclusion of the instant sales contract. Thus, insofar as it is evident that the Plaintiff’s development in the instant sales contract was involved in the conclusion of the contract in the buyer’s status, the validity of the instant sales contract for business transfer and takeover does not reach any effect in the instant sales contract, and ultimately, the buyer’s status cannot be deemed to have been transferred to the Plaintiff Y.

In this regard, the defendants and the independent party intervenor disputing the status of purchaser of the development of the plaintiff Song-sung Industry.
