United States v. Third Nat. Bank in Nashville

Background

The United States challenged a 1964 merger that joined Third National Bank in Nashville (a large, aggressive bank) with Nashville Bank and Trust Company (a smaller, stagnating but profitable bank). The Comptroller of the Currency approved the merger on August 4, 1964; the two banks merged on August 18, 1964. The Justice Department sued under the Clayton Act, but the District Court upheld the merger, finding the transaction would not substantially lessen competition and that any harm was outweighed by benefits to the community.

Reasoning

The Supreme Court examined whether the merger would “tend substantially to lessen competition” and whether the banks proved that community “convenience and needs” clearly outweighed any anticompetitive effects. The Court held the District Court used the wrong standard and applied ordinary antitrust principles instead. On the record, the merger increased concentration sharply (the three largest banks’ share rose from about 93% to about 98%), and Nashville Bank was not shown to be a failing company. The Court found the Government proved the merger tended to lessen competition and faulted the lower court for not showing the claimed community benefits were sufficient to outweigh that harm. The Court also said merging banks must show reasonable alternatives to merger were unavailable.

Real world impact

The decision requires bank mergers to be judged by the usual antitrust analysis and makes clear that claims of local convenience and improved services must be proved and weighed against lost competition. The case was reversed and remanded so the District Court can reweigh and, if appropriate, reopen the record in light of this opinion; the outcome is therefore not final.

Dissents or concurrances

Justice Harlan (joined by Justice Stewart) agreed a Clayton Act violation was shown but thought the District Court had made adequate findings about management alternatives; he would limit further review to the balancing step.
