Why Did the Court Cancel the FIU Suspension?
A South Korean court has overturned a three-month partial business suspension imposed on Dunamu, the operator of crypto exchange Upbit, marking a setback for the country’s financial regulator. The Seoul Administrative Court ruled in favor of Dunamu, canceling the sanction issued by the Financial Intelligence Unit (FIU) over alleged Anti-Money Laundering (AML) violations.
The case centered on whether Dunamu had failed to meet compliance requirements tied to transaction monitoring and customer due diligence. The court found that while clear rules existed for transactions above 1 million won (around $675), guidance for smaller transfers lacked sufficient specificity to support enforcement.
This gap weakened the legal basis for the FIU’s action, particularly in areas where compliance expectations were not clearly defined in practice. The ruling effectively limits the regulator’s ability to impose strict penalties when operational standards are not fully articulated.
What Did the Court Say About AML Compliance?
In addressing the FIU’s claims, the court stated that the regulator had not provided detailed guidance on what actions Dunamu was expected to take. Without clearly defined requirements, the court concluded that the exchange had implemented its own compliance measures within a reasonable framework.
The ruling also noted that even if those measures were insufficient in hindsight, it was difficult to establish intent or gross negligence. This distinction was critical in undermining the justification for imposing a suspension on the business.
The decision introduces a higher threshold for enforcement, particularly in cases where regulators rely on broadly defined AML expectations rather than precise operational standards.

How Did the Dispute Between Dunamu and the FIU Unfold?
The dispute dates back to February 25, 2025, when the FIU imposed a three-month partial suspension on Dunamu following an on-site inspection. The sanction restricted new Upbit users from transferring digital assets, citing violations linked to transactions with unregistered overseas virtual asset providers and failures in customer due diligence.
The regulator also reported identifying more than 600,000 suspected Know Your Customer violations during its review of Upbit’s exchange license. These findings formed the basis for one of the most serious enforcement actions taken against a South Korean crypto platform.
Dunamu responded by filing a lawsuit and seeking an injunction to halt the suspension. On March 27, 2025, the court granted the injunction, allowing the exchange to continue onboarding new users while the case was under review.
Investor Takeaway
What Does This Mean for Crypto Regulation in South Korea?
The ruling highlights a structural issue in crypto regulation: the gap between high-level policy intent and operational clarity. While South Korea has been active in enforcing AML standards, this case suggests that courts may require more detailed guidance before supporting punitive measures.
That said, the outcome may prompt a reassessment of how compliance rules are written and communicated to market participants. More explicit standards could be needed to sustain future enforcement actions.
As for exchanges, the decision provides temporary relief but also underscores the importance of documenting internal compliance efforts, especially in areas where regulatory expectations remain ambiguous.
