The Seoul Administrative Court on Thursday rejected Coupang’s injunction lawsuit against a fine of about 423 billion won, or $315 million, imposed by the Personal Information Protection Commission over a data breach affecting more than 37 million users. The commission imposed the penalty in June for privacy violations, including the exposure of names, phone numbers and delivery details, making it the largest fine the regulator has levied against a single company. The court found no basis to nullify the fine; financial losses from payment can be addressed through compensation, according to the existing record. Coupang separately secured a suspension of corrective and public-disclosure orders until 30 days after the main lawsuit’s verdict, and its cancellation lawsuit remains pending, so the ruling does not finally determine whether all sanctions were lawful. The new report gives the fine as about 423 billion won, while the existing record specifies 423.575 billion won and previously cited a separate 624.7 billion won figure; the discrepancy remains unresolved. Coupang reported the breach more than six months after it occurred last November. South Korean law permits fines of up to 3% of annual sales, excluding unrelated revenue, and Coupang averaged about 36 trillion won in annual sales over the past three years. The incident also generated friction between Seoul and Washington after some U.S. officials and lawmakers questioned whether Coupang’s Korean unit was treated unfairly.
