A Study on the Judgment Recognizing State Compensation Liability in the Humidifier Disinfectant Damage Case: Focused on the Seoul High Court Verdict Announced on February 6, 2024, Case No. 2016Na2086563

The “Humidifier Disinfectant Incident,” where numerous citizens suffered serious health damages from humidifier disinfectants sold in Korea from 1994 to 2011, can be attributed to the irresponsible actions of companies that failed to ensure product safety and the negligence of the government and related organizations in properly managing and supervising these products. Victims and their families claimed damages against manufacturers and the state, but only the manufacturers' liability for damages was primarily recognized, with state compensation liability not being acknowledged. Additionally, the court decided on the liability of manufacturers and sales companies based on whether the primary ingredient of the humidifier disinfectant was of the P series (PHMG/PGH) or C series (CMIT/MIT). Around January 2012, the Seoul Central District Court, through the 2012Gahab4515 damages case, dismissed the claims of the victims and their families on January 19, 2015, not recognizing the state's fault. However, recently, on February 6, 2024, the Seoul High Court issued a significant ruling through case 2015Na2014486, marking the first time state compensation liability was recognized in this matter. This judgment emphasizes the responsibility of the state and relevant agencies in the safety assessment and supervision process of chemicals, reaffirming the importance of state measures to protect the health and safety of its citizens. Notably, this ruling provides critical insights on how the state should respond to ensure citizens' rights to a healthy and comfortable environment against harmful chemicals. Therefore, this study examines the significant legal grounds and principles through this landmark decision, affirming the state's legal responsibilities and duties in public health management and crisis response through chemical management, thereby contributing to reestablishing the role of the state in protecting the lives and safety of its citizens.
