 (1) Statements and examination of evidence submitted this time 

The above written statements and evidence were examined. 

Attorney Shima, representing the plaintiffs, gave a 30- minute presentation on the contents of the complaint. 

 (2) Future progress 

According to the defendant's written response, the issues in this case are: (1) whether the violated interest was a legally protected one, (2) what duty of care the defendant had, and to which duty of care the inaction violated, and (3) a request for clarification regarding the reciprocal guarantee under the National Compensation Act. 

Next time, the plaintiffs will prepare their counterarguments to points ① and ②, and their response to point ③. 

Attorney Shima, representing the plaintiffs, mentioned that while the written answer stated that the rights currently being violated did not arise from government policies, and the plaintiffs' argument boils down to the fact that the government has not implemented sufficient policies at the time of filing this lawsuit, which violates upon their right to a peaceful life, and asked that this point be confirmed.

The next oral hearing date has been set for Thursday, March 4 , 2027 , at 3:00 PM. 

In the meantime, to confirm the progress since the first oral argument hearing, procedural conferences are scheduled to be held on December 10, 2026 , at 4:00 PM and on February 4, 2027 , at 4:00 PM . 

 Thanks to everyone's support, the gallery was full. Let's fill the gallery again for the next hearing! 

 We appreciate your continued support.

Following the first lawsuit filed on December 18, 2025 (with 452 plaintiffs), a second lawsuit was filed on April 2, 2026, adding another 454 plaintiffs. As a result, the number of plaintiffs has exceeded 900, and they are raising questions to the government as a much larger voice of citizens. Furthermore, we plan to request the court to consolidate the first and second lawsuits and proceed with them as a single case.
