1. According to the written evidence Nos. 1 through 3 and the overall purport of testimony and pleading by the witness C of the first instance trial, it is difficult to recognize the fact that the office of education gave contracts to adults, and re-subcontracts to the Plaintiff around January 1, 2015, the Defendant re-subcontracted “D middle school ventilation Facility Improvement Works” to the Defendant for KRW 9 million, which was subcontracted to the Defendant by adults, around January 15, 2015, and that the Plaintiff completed the said construction around February 15, 2015, and only the written evidence No. 1 is insufficient to reverse the said recognition.
