Whether 12 U.S.C. § 85 governs the interest rate charged by Omaha Bank even though the suit proceeded against its service subsidiary rather than Omaha Bank itself.
Holding
Yes. The rate Omaha Bank may charge on its credit-card loans is governed by federal law because Omaha Bank is a national bank.
Reasoning
Omaha Bank was no longer a defendant after Marquette dismissed it to prevent removal to federal court, but the dispute still turned on whether Omaha Bank's credit-card program could lawfully charge Minnesota residents Nebraska's interest rate. The Court therefore addressed the application of § 85 to the program.
A national bank is a federal instrumentality subject to Congress's paramount authority. Under § 85, the permissible interest rate on a national bank's loans is a matter of federal law, not a matter left to contrary state regulation. The Court did not decide whether Omaha Service Corp., participating merchants, or participating Minnesota banks would be subject to Minnesota law if they themselves extended credit, because no such allegation was before it.
