2. Determination

A. According to the above facts of recognition as to the cause of the claim, the Defendants, as joint contractors, are jointly and severally liable to pay the Plaintiff the amount of 531,130,000 won unpaid and the damages for delay calculated at the rate of 12% per annum from November 14, 2019 to the date of full payment, as the Plaintiff seeks.

B. The Defendants asserted that the Defendants did not pay the construction price to the Plaintiff because they failed to receive the construction price from the enforcement company.

However, in light of the contents of the instant subcontract, it is difficult to view the reasons asserted by the Defendants as grounds for refusing to pay the construction cost, and thus, we cannot accept the Defendants’ assertion.

3. In conclusion, the plaintiff's claim against the defendants of this case against the defendants is justified, and it is so decided as per Disposition.
