Debate over retroactive application of Collective Lawsuit Act... Ruling party: 'No problem,' Opposition: 'Unreasonable move targeting Coupang'

A contentious debate has erupted in the South Korean National Assembly over the proposed Collective Lawsuit Act, particularly concerning its potential retroactive application. The core of the disagreement lies in whether the law, designed to allow a group of plaintiffs to benefit from a single successful lawsuit, should apply to incidents that occurred before its enactment. This issue has become a focal point, especially in light of the massive personal information leak from e-commerce giant Coupang.

While full retroactivity is difficult, partial retroactivity should be recognized. There is no problem as the Supreme Court has also acknowledged it.

The Democratic Party (DP) is strongly advocating for the retroactive application of the law, arguing it is essential for providing timely and effective relief to victims of the Coupang data breach. DP lawmaker Jeon Hyun-hee stated that while full retroactivity might be difficult, partial retroactivity—applying the law to ongoing cases or situations—is both necessary and legally feasible, citing Supreme Court precedents. This stance positions the DP as a champion for consumer rights against large corporations.

Conversely, the People Power Party (PPP) has voiced strong opposition, with lawmakers like Na Kyung-won and Yoon Sang-hyun expressing concerns. Na Kyung-won questioned whether the push for retroactivity was specifically targeting Coupang, suggesting it could lead to diplomatic issues if perceived as a politically motivated move against a foreign-invested company. Yoon Sang-hyun warned that retroactive application could expose businesses to a flood of "lawsuits without reason" (묻지 마 소송), potentially creating an unstable business environment. This perspective highlights the PPP's focus on protecting corporate interests and maintaining economic stability.

I deeply express my concern that if retroactivity is indiscriminately recognized in this law, targeting Coupang, it could escalate into a diplomatic issue.

The current Collective Lawsuit Act in South Korea is limited to the securities sector, enacted in 2005. The recent surge in data breaches and other consumer-related incidents has spurred legislative efforts to broaden its scope. From a South Korean perspective, this debate reflects a broader societal tension between protecting consumers from corporate misconduct and fostering a favorable environment for businesses, particularly foreign investors. The outcome of this legislative battle will have significant implications for corporate accountability and consumer protection in the country.

If retroactive application is included in the Collective Lawsuit Act, businesses will have to bear the risk of 'lawsuits without reason.'
