A. The Plaintiff, by September 7, 2019, supplied used materials, etc. to Defendant B to Defendant C until October 4, 2018, but failed to receive the goods amounting to KRW 11,264,100 from Defendant B, and KRW 7,564,00 from Defendant C. As such, the said Defendants are liable to pay each of the above amounts and damages for delay to the Plaintiff.

(b) Articles 208 (3) 2 and 150 (3) of the Civil Procedure Act of each applicable provisions of Acts;
