Dunamu, the operator of South Korean crypto exchange Upbit, has won its legal challenge against the Financial Intelligence Unit (FIU) under the Financial Services Commission. The Seoul Administrative Court overturned the three-month partial business suspension previously imposed on the company.
Court Focuses on Regulatory Clarity
At the center of the case was whether South Korea’s compliance requirements for virtual asset transactions below 1 million Korean won were sufficiently clear. The court found that the relevant rules and obligations lacked clarity, a key factor behind its decision to cancel the FIU’s sanction.
The ruling also rejected the view that Dunamu had acted intentionally or with gross negligence. According to the court, the company had already implemented meaningful compliance steps, including obtaining customer commitments and using its monitoring system to identify wallet addresses and block transactions involving unregistered entities.
Compliance Efforts Strengthened Dunamu’s Case
The decision suggests that the court placed significant weight on Dunamu’s internal controls and transaction monitoring framework. In effect, the judgment recognized that the company had taken practical measures to manage risk even in an environment where the regulatory standard was not fully defined.
The outcome may carry broader implications for South Korea’s crypto sector. Beyond its immediate impact on Dunamu and Upbit, the ruling highlights ongoing tension between regulatory enforcement and legal certainty in the country’s virtual asset market.
So far, the available report is focused on the court’s reasoning and the reversal of the penalty, with no additional details yet disclosed on any further regulatory response.
