Violation

Machine-translated summary — verify against original

The construction company was the prime contractor for a project ordered by Hokkaido but submitted the construction management ledger to the client without realizing that a subcontractor had assigned the work to an individual business owner (one-man contractor), and that the subcontractor's workers were listed in the ledger. This constitutes a violation of Article 28, Paragraph 1, Item 2 of the Construction Business Act.
