National Credit Union Administration v. First National Bank & Trust Co.

The National Credit Union Administration (NCUA) (defendant) interpreted the Federal Credit Union Act's requirement that federal credit union membership share a common bond of occupation or association to permit federal credit unions, like AT&T Family Federal Credit Union, to add multiple unrelated employer groups as members so long as each group had its own internal common bond. Five commercial banks (plaintiffs), which compete with credit unions for customers, sued under the Administrative Procedure Act challenging the NCUA's approval of this membership expansion, and the case reached the Supreme Court.
