Recently, there has been an increasing number of cases where the Prosecutor’s Office (“PO”) initiated investigations on antitrust matters traditionally first taken up by the Korea Fair Trade Commission (the “KFTC”), such as violations of the Monopoly Regulation and Fair Trade Act (the “MRFTA”) and bid rigging. While it is not unheard of for the PO to take the initiative in probing violations of the law, the general practice in the antitrust arena has been for the PO to wait until the KFTC completes its investigation and files criminal charges with the PO. This new trend in Korean antitrust enforcement is worth taking notice for companies doing business in Korea as the investigation authorities and processes become more multifaceted.
