Chapter 50 – The Clayton Act, the Robinson–Patman Act, and Antitrust Exemptions and Immunities
b. The Warren Court (the Supreme Court from the mid-1950s to 1969) plainly agreed
with the anticoncentration thrust of Section 7, and sometimes struck down mergers
whose potential anticompetitive effect was dubious at best. For an example, see
United States v. Von’s Grocery Co., 384 U.S. 270 (1966), a case that may represent
the high-water mark of Section 7 enforcement.
c. Although the Burger Court (the Court from 1969 to 1986) did not expressly overrule
any of the Warren Court’s major merger decisions, United States v. General
Dynamics, 415 U.S. 486 (1974), signaled an intent to insist on more in the way of
proof of probable anticompetitive effect. Several lower court opinions that followed
evidenced a similarly increased tolerance for horizontal mergers. The Rehnquist
Court did not show any tendency to curb this trend, and it seems unlikely that the
current Roberts Court will. In Cargill, Inc. & Excel Corp. v. Monfort of Colorado,
Inc., 479 U.S. 104 (1986), the Court stopped short of holding that competitors lack
standing to challenge mergers under section 7. Instead, the Court held that the
plaintiff-competitor had failed to demonstrate that the proposed merger posed a threat
of antitrust injury, and that losses or damage flowing from increased competition do
not constitute such an injury. The dissenters, Justices Stevens and White, argued that
the practical effect of the Court’s decision was to prevent private parties from
obtaining injunctive relief against a horizontal merger unless they could demonstrate
that the actual or probable conduct of the merged firms would violate the Sherman
Act. They argued that by emphasizing the post-merger conduct of the merged firms,
the Court “reduces to virtual irrelevance the related but distinct issue of the legality of
the merger itself.”
d. Discuss the approach to horizontal mergers adopted by the federal government’s
merger guidelines.
1) Note the obvious need to examine the degree of concentration in the existing
market and the increase in concentration that would result from the proposed
merger.
2) Discuss the nonmarket share factors that the Justice Department and the FTC
will consider in deciding whether to challenge a merger: the existence of barriers
to the entry of new competitors into the relevant market; the prior conduct of the
merging firms; and the probable future competitive strength of the acquired firm
(is it a “failing company” or a firm with competitive disadvantages that are not
reflected in its present market share?). Note also the potential for federal
regulators to consider economic efficiency claims as justifications for a
horizontal merger. The Warren Court, in Philadelphia National Bank, clearly
rejected the notion that enhanced efficiency could ever justify a horizontal
merger that would result in a probable harm to competition. The merger
guidelines, however, do not foreclose such a conclusion by federal regulators
when they decide whether to challenge a particular merger.
ProMedica Health System, Inc. v. FTC (p. 1377): The U.S. Court of Appeals
upholds the FTC’s determination that a merger between ProMedica and one of its
rivals (St. Luke’s) likely would substantially lessen competition in the market for
acutee care services, and thus violated Section 7 of the Clayton Act. The Sixth
Circuit also upholds the FTC’s order that ProMedica divest itself of St. Luke’s.
Points for Discussion: Have the students identify the relevant geographic markets
and the relevant product markets. Walk the students through the analysis the
court uses in identifying (as did the FTC) the relevant product markets as (1)
primary services (except for OB) and secondary inpatient services, and (2) OB
