1. On October 30, 2013, in relation to the incident mainly involving E-vehicles at D stations located in Gangseo-gu Seoul Metropolitan Government.

1. The plaintiff sought confirmation that there is no obligation to compensate remaining in relation to the same difference as the same difference in this case as the principal lawsuit, while the defendant, as a counterclaim, claims that the plaintiff's obligation to compensate for damages due to the same difference in this case remains, and claims the performance of the obligation to compensate for damages.

However, inasmuch as the obligation to prove the existence of the damage claim caused by the instant confusion lies in the defendant regardless of the principal lawsuit and the counterclaim, it is necessary to first examine the validity of the defendant's counterclaim for convenience, and then examine the validity of the plaintiff's claim.
