In light of a recent ruling by the U.S. Supreme Court declaring the tariffs imposed by the Trump administration as unconstitutional, the civic group 참여연대 (Citizen's Coalition for Economic Justice) has called for a thorough reassessment of South Korea's $350 billion investment plan in the United States, which was initially predicated on these tariffs. The group contends that it is unreasonable for the South Korean government to adhere to the results of the U.S.-Korea agreement under such circumstances where the foundational tariff agreements are now void. They argue that rather than pursuing the legislation for a special investment law, discussions should begin for a renegotiation of the existing terms.

The civic group's commentary highlights the unexpected turn following the Supreme Court's decision and poses questions about the validity of the investment negotiations that formed the backdrop for these tariffs. They point out that the Trump administration's immediate announcement regarding a new 'global tariff' approach after the ruling represents a significant shift that necessitates re-evaluating the current investment obligations. The group stresses that continuing to enforce the existing agreements without reconsideration could lead to further economic disadvantages for South Korean exporters, especially in key sectors like automotive and semiconductors.

Furthermore, 참여연대 is advocating for the South Korean government to publicly acknowledge that the basic premise of the U.S.-Korea agreement has changed following the Supreme Court's decision. They are requesting a formal declaration of the nullification of the investment agreement and swift actions toward renegotiation. Additionally, they call for measures to assist South Korean export firms that have been affected by the tariffs, seeking ways to secure tariff refunds for these companies based on the new legal landscape surrounding tariffs.
