The U.S. Supreme Court case Omaha National Bank v. Nebraskans for Independent Banking, Inc., et al., 1975 revolved around the issue of whether a national bank could relocate its main office to another location within the same state without losing its status as a national bank under federal law. The Omaha National Bank sought to move from downtown Omaha to suburban Westgate but was opposed by local independent banks and banking associations who argued that such relocation would violate Nebraska's intrastate branching laws which prohibited branch banking in most areas of the state. The Supreme Court ruled in favor of the Omaha National Bank, stating that federal law preempted state law on this matter and thus allowed for relocation without loss of national charter or violation of Nebraska’s anti-branching laws.

In the dissenting opinion for Omaha National Bank v. Nebraskans for Independent Banking, Inc., Justice William O. Douglas argued that the majority's decision to allow national banks to relocate their main offices within a 30-mile radius violated the intent of Congress when it passed banking laws in 1882 and 1927. He contended that these laws were designed to restrict national banks from moving into new territories without state approval, as part of an effort by Congress to balance federal and state powers over banking regulation. The majority's interpretation, he believed, undermined this balance by giving national banks more freedom than intended under these statutes. Furthermore, Douglas expressed concern about potential negative impacts on local communities if large out-of-state or multinational corporations could easily move their bank branches into those areas.
