Violation

The former sales manager of Inomata Construction Co., Ltd. conspired with a former city official of Itoigawa City regarding the restricted open bidding for the 'New Station Public Toilet Construction Project' conducted on December 8, 2020. The city official provided confidential information, including the estimated price, which the former manager used to submit a bid close to the suggested price, thereby impairing the fairness of the public bidding process. The former manager was convicted under Articles 60 and 96-6(1) of the Penal Code for obstructing public contract bidding, receiving a sentence of one year in prison with a three-year suspension, which was finalized on September 11, 2021. This conduct was recognized as a violation of Article 28(1)(2) of the Construction Business Act. As a result, the Hokuriku Regional Development Bureau ordered a 60-day suspension of construction business activities in Niigata, Toyama, and Ishikawa prefectures from December 24, 2021, to February 21, 2022.
