2. Additional determination

A. 1) The Plaintiff asserts that, even if the Plaintiff is liable for the return of the lease deposit against the Defendants, the Defendants are negligent in not verifying the existence of the right of representation under Article 396 of the Civil Act, so that the Plaintiff ought to limit the Plaintiff’s liability according to the reasoning of the principle of offsetting of negligence or liability for negligence under Article 396 of the Civil Act. 2) The offsetting of negligence is recognized as a tort liability for nonperformance or tort (see, e.g., Supreme Court Decision 2013Da34143, Mar. 13, 2014). As seen in the instant case, this does not apply to cases where the Plaintiff seeks the return of the lease deposit based on the lease contract

In addition, it is allowed to limit the content of the contractual rights to the contract, based on the principle of good faith or fairness, and the principle of liability for negligence, on the ground that there is some negligence in the process of concluding the contract in case of seeking performance according to the contractual terms.
