1. Facts of recognition;

A. The Defendant consented to the Plaintiff’s credit card individual member agreement, etc. and was admitted as the Plaintiff’s member, and was issued a credit card by the Plaintiff, and delayed payment from January 25, 2019.

[Ground of recognition] Facts without dispute, entry of evidence A1 to 8, purport of the whole pleadings

2. According to the above facts of determination, the Defendant is obligated to pay to the Plaintiff delay damages for the amount of KRW 1,922,334 in total and the amount of KRW 123,306 in lump sum from March 19, 2019 to the date of full payment, 15.5% per annum for lump sum payment, KRW 22.5% per annum for installment payment, KRW 347,100 for principal, and KRW 22.5% per annum for cash service, KRW 1,387,985 per annum for each agreed interest rate.

The defendant asserts that the plaintiff unilaterally applied high interest rate, but each of the above overdue interest rate is legitimate as it is in accordance with the plaintiff's personal member agreement, which the defendant consented to the plaintiff's membership. Thus, the defendant's argument is without merit.

3. Conclusion, the plaintiff's claim of this case should be accepted as reasonable.

The judgment of the court of first instance is justifiable in its conclusion, and the defendant's appeal is dismissed. It is so decided as per Disposition by the assent of all participating Justices.
