Opinion by

We granted certiorari pursuant to C.A.R. 50 to review the district court’s decision in Richardson v. Citibank (South Dakota), N.A., No. 92CV1460 (Colo.Dist.Ct. Mar. 21, 1994). The district court granted summary judgment in favor of Citibank (South Dakota), N.A. (Citibank), holding that section 85 of the National Bank Act (NBA), 12 U.S.C. section 85 (1982), preempts section 5-3-203(5)(a) of the Colorado Uniform Consumer Credit Code (UCCC), section 5-3-203(5)(a), 2 C.R.S. (1992). The district court allowed a national bank located in South Dakota to charge a fifteen dollar late payment fee in addition to a finance charge to the credit card accounts of its Colorado customers. Susan L. Richardson (Richardson) and Citibank jointly petitioned, pursuant to C.A.R. 50, for a writ of certiorari to review this ease before judgment by the court of appeals. We affirm the judgment of the district court, but we base our decision on different grounds.

The respondent, Citibank, is a national bank located in South Dakota which issues VISA and MasterCard credit cards. The petitioner, Richardson, a Colorado resident, became a Citibank VISA credit card member. When Richardson failed to make a minimum monthly payment, Citibank assessed her VISA credit card account a fifteen dollar late payment fee. Richardson initiated this class action, on behalf of herself and all others similarly situated, alleging that Citibank’s imposition of a late payment fee violated section 5-3-203(5)(a) of the UCCC, section 5 — 3—203(5)(a), 2 C.R.S. (1992). Citibank contends that section 85 of the NBA, 12 U.S.C. section 85 (1982), preempts the Colorado consumer protection law.

Copeland v. MBNA Am. Bank, N.A., 907 P.2d 87 (Colo. 1995), is dispositive of the issue in this ease. There, this court held that, as a matter of federal law, a late payment fee imposed on a customer’s credit card account is a form of “interest” under section 85 of the NBA, 12 U.S.C. section 85 (1982). 1 This court held that federal law authorized a national bank located in Delaware to assess a fifteen dollar late payment fee, allowed under Delaware law, to the credit card account of a Colorado resident despite the fact that a Colorado consumer protection law prohibited such fees.

Accordingly, applying that decision to Richardson, we conclude that because Citibank is a national bank located in South Dakota, and South Dakota law permits the *534 imposition of a late payment fee, Citibank can charge Richardson a late payment fee despite the fact that a Colorado consumer protection law prohibited such fees. Hence, we affirm the judgment of the district court.
