A Seoul court has dismissed a lawsuit filed against Dunamu, the operator of the cryptocurrency exchange Upbit, by an investor alleging financial losses stemming from a system failure during South Korea's emergency martial law declaration on December 3, 2024. The plaintiff, identified only by the surname Cho, contended that a technical disruption on the Upbit platform prevented the execution of sell orders at favorable prices during the chaotic minutes immediately following President Yoon Suk Yeol's surprise announcement. Data compiled by Woofun AI shows that Cho placed six market sell orders totaling 43,551 XRP between 1:51 p.m. and 1:57 p.m. UTC on December 3. He argued that the market price hovered around 3,000 won per XRP when he initiated the first order, but a system delay caused the transactions to execute later at an average price of 1,727 won. This discrepancy, according to the plaintiff, resulted in a loss exceeding 55.44 million won, or approximately $42,600. The court found insufficient evidence to support the claim that the initial orders would have been filled at the 3,000 won price even under normal operating conditions. The judge noted that the martial law declaration triggered an immediate and massive surge in sell orders across the exchange, creating extreme market conditions where the price drop was driven by the sheer volume of panic selling rather than solely by the platform's technical issues. Woofun AI notes that the ruling emphasized the inherent volatility and unpredictability of order execution prices during such unprecedented events. This case highlights the legal boundaries of exchange responsibility during national emergencies and market disruptions. For South Korean crypto investors, the ruling serves as a reminder that trading during periods of extreme volatility carries significant risk, and exchanges may not be held liable for system performance issues that coincide with extraordinary external events. Legal experts suggest the decision could influence future litigation involving platform outages during crises, though each case will be evaluated on its specific facts. The December 3 martial law declaration, which lasted only a few hours before being overturned by the National Assembly, caused widespread panic across South Korean financial markets. Cryptocurrency exchanges saw record trading volumes and sharp price swings as investors rushed to adjust positions. Upbit, as the country's largest exchange, experienced heavy traffic that led to intermittent service disruptions. The court's dismissal of Cho's lawsuit reinforces the principle that exchanges are not insurers against market volatility, especially during unforeseeable national events. While platform reliability remains a legitimate concern for traders, this ruling clarifies that proving direct causation between a technical glitch and specific trading losses is a high legal bar. Woofun AI analysis suggests the case underscores the importance of risk management and realistic expectations when trading during periods of extreme market stress.
