The case, Harper v. Faulkender, petitioned the court to re-examine a decades-old ruling which held that bank customers don’t have privacy rights to records held by their financial institutions.

This “third-party doctrine” has long been critiqued by conservative scholars who claim it infringes on user privacy. In 2018, the Supreme Court made an exception to the principle, ruling that in the case of cell phone records held by phone carriers, a warrant is needed to access certain customer data.
