Golden Finance reported that Dunamu, an operator of the South Korean virtual asset exchange Upbit, has filed a lawsuit with the Seoul Administrative Court, demanding the revocation of the business suspension order implemented by the South Korean Financial Intelligence Department (FIU) and apply for a temporary suspension of execution. Earlier, FIU made several penalties on February 25 on the grounds of violating the Specific Financial Information Act, including a three-month business suspension for nine employees, a warning to CEO Lee Seok-woo and a dismissal of the compliance officer. The suspension order will limit the transfer of virtual assets for new customers from March 7 to June 6.
