HWASEONG, SOUTH KOREA — South Korea’s Supreme Court on 20 October 2026 upheld a four-year prison sentence for Aricell chief executive Park Soon-kwan in the case arising from the battery factory fire that killed 23 workers in June 2024. The decision makes the reduced appellate sentence final; it is a new judicial development, not a new factory incident.
Yonhap’s court report and separately bylined reporting from SBS, The Korea Times and Seoul Economic Daily agree on the central outcome. The case concerns management responsibility for workplace hazards at the lithium battery manufacturer’s Hwaseong plant.
What the Supreme Court left in place
The top court dismissed appeals and allowed the appellate judgment to stand, according to the reports. Park’s son, a senior Aricell executive, received a final seven-year prison term. The Korea Times and Seoul Economic Daily also reported that the company’s 800 million won fine was upheld.
The chief executive had originally received a 15-year sentence. The appeal court reduced it after rejecting some charges relating to emergency-exit requirements and considering settlements with bereaved families. The Supreme Court did not restore the original sentence.
This distinction matters: the judgment does not mean that every allegation in the initial prosecution survived appeal. It also does not remove the convictions that remained in force.
Hazard identification and executive responsibility
Seoul Economic Daily’s account of the ruling says the court treated the executive with overall business responsibility as subject to duties under the Serious Accidents Punishment Act, including in areas where that executive retained final decision-making authority despite the appointment of a separate safety officer.
Its report also describes a distinction between having risk-assessment procedures on paper and operating procedures that identify and address the actual hazards of a lithium battery manufacturing site. The newspaper reported that Aricell’s arrangements did not adequately reflect those specific risks.
The incident and the limits of the exit finding
The fire occurred on 24 June 2024 at the Hwaseong facility. Twenty-three workers died and nine were injured. The Korea Times reported that the blaze spread rapidly in a second-floor area where finished batteries were inspected and packaged.
SBS’s report on the final appeal confirms that the appellate court’s narrower interpretation of emergency-exit obligations was part of the reduced sentence. The reporting describes a legal question about building-level requirements, rather than a general finding that escape planning was unnecessary.
Employers elsewhere should not treat that jurisdiction-specific interpretation as permission to reduce evacuation safeguards. Applicable laws, the particular process and the assessed risk remain essential.
HSE Blog analysis: connect the assessment to the operation
The practical management issue is whether an assessment leads to controls workers can use. A workplace fire risk assessment should address the actual materials, tasks and people at risk, rather than simply reproduce a generic checklist.
That work must connect with emergency response planning, training and drills. Responsibility, escalation and evacuation arrangements need to remain clear when production methods or staffing change. These are HSE Blog’s general observations, not additional findings attributed to the Korean court.
