2. The parties' assertion

A. Since the Plaintiff’s assertion entered into a contract with Defendant C on the instant construction project and completed the instant construction project, Defendant C is obligated to pay the construction cost of KRW 5,009,00 and the delay damages.

Since Defendant B, as the owner of the apartment of this case, instructed or supervised the construction of this case with Defendant C, it is jointly and severally liable to pay the construction cost of this case with Defendant C.

Defendant C is liable for the payment of the instant construction cost by demanding the Defendant C to issue a tax invoice for the instant construction work under the name of the Defendant Company. As such, Defendant C is jointly and severally liable for the payment of the instant construction cost.

B. The Defendants’ assertion did not require the Plaintiff to perform the instant construction work or conclude a contract for construction work.

In other words, when problems arise such as defective construction after Defendant C’s dental hospital construction work was performed by Defendant C, the instant construction work was performed at cost without profit, and only Defendant C left Defendant C with the instant construction work.

Furthermore, Defendant C filed a lawsuit seeking confirmation of the existence of an obligation against E in relation to the above two projects and obtained a favorable judgment, and thus, Defendant C did not have any obligation to be borne any more in relation to the instant project.
