Criminal appeal case regarding the Samsung Electronics carbon dioxide leak accident

Lee & Ko represented Samsung Electronics in an appeal regarding the case in which the company’s executives and employees were indicted and found guilty in the court of first instance of occupational negligence resulting in injury or death. The case arose from an accident at Samsung Electronics’ Giheung facility, where a carbon dioxide leak during the replacement of fire-fighting equipment resulted in three casualties. Through meticulous legal analysis and a thorough examination of the evidence, Lee & Ko developed the optimal defense strategy and ultimately secured an acquittal for Samsung Electronics’ executives and employees. Lee & Ko is currently representing the client in the appeal before the Supreme Court. 

The accident occurred when an improperly cut active wire triggered the carbon dioxide fire extinguishing system to operate, causing the connected selector valve to detach because it failed to withstand the pressure of the carbon dioxide, ultimately resulting in carbon dioxide leaking to the outside. 

In the first instance, the court determined that the accident was caused by the construction company’s negligence in improperly cutting an active wire, as well as Samsung Electronics’ executives and employees who failed to adequately manage the selector valve that emits carbon dioxide. The court thus found Samsung Electronics’ executives and employees guilty of occupational negligence resulting in injury or death.

Samsung Electronics retained Lee & Ko as its new counsel for the appeal. Lee & Ko emphasized that the detachment of the selector valve was a manufacturing defect, and that there was no legal or factual basis for imposing an obligation on Samsung Electronics, which simply purchased and used the selector valve, to inspect its pressure resistance. At the same time, Lee & Ko meticulously analyzed and contended that the first instance decision erroneously conflated civil law principles of product liability with criminal legal principles of occupational negligence. The appellate court sided with Lee & Ko’s arguments, acquitting Samsung Electronics’ executives and employees and overturning the first instance decision. This case exemplifies Lee & Ko’s strong advocacy skills to present the most effective case strategy and solution for clients.
