United States, 524 U.S. 236, 251, 118 S.Ct. 1969, 141 L.Ed.2d 242 (1998).
[11]Stare decisis is not as significant in this case, however, because the issue before us is the scope of the Sherman Act. Khan, supra, at 20, 118
S.Ct. 275 (“[T]he general presumption that legislative changes should be left to Congress has less force with respect to the Sherman Act”).
From the beginning the Court has treated the Sherman Act as a common-law statute. See National Soc. of Professional Engineers v. United
States, 435 U.S. 679, 688, 98 S.Ct. 1355, 55 L.Ed.2d 637 (1978); see also Northwest Airlines, Inc. v. Transport Workers, 451 U.S. 77, 98, n. 42,
Department of Justice and the Federal Trade Commission-the antitrust enforcement agencies with the ability to assess the long-term impacts
of resale price maintenance-have recommended that this Court replace the per se rule with the traditional rule of reason. See Brief for United
States as Amicus Curiae 6. In the antitrust context the fact that a decision has been “called into serious question” justifies our reevaluation of
it. Khan, supra, at 21, 118 S.Ct. 275.
Other considerations reinforce the conclusion that Dr. Miles should be overturned. Of most relevance, “we have overruled our precedents
when subsequent cases have undermined their doctrinal underpinnings.” Dickerson v. United States, 530 U.S. 428, 443, 120 S.Ct. 2326, 147
L.Ed.2d 405 (2000). The Court’s treatment of vertical restraints has progressed away from Dr. Miles ‘ strict approach. We have distanced
ourselves from the opinion’s rationales. See supra, at 2713 – 2714; see also Khan, supra, at 21, 118 S.Ct. 275 (overruling a case when “the
views underlying [it had been] eroded by this Court’s precedent”); Rodriguez de Quijas v. Shearson/American Express, Inc., 490 U.S. 477, 480-
481, 109 S.Ct. 1917, 104 L.Ed.2d 526 (1989) (same). This is unsurprising, for the case was decided not long after enactment of the Sherman Act
when the Court had little experience with antitrust analysis. Only eight years after Dr. Miles, moreover, the Court reined in the decision by
holding that a manufacturer can announce suggested resale prices and refuse to deal with distributors who do not follow them. Colgate, 250
U.S., at 307-308, 39 S.Ct. 465.
In more recent cases the Court, following a common-law approach, has continued to temper, limit, or overrule once strict prohibitions on
vertical restraints. In 1977, the Court overturned the per se rule for vertical nonprice restraints, adopting the rule of reason in its stead. GTE
Sylvania, 433 U.S., at 57-59, 97 S.Ct. 2549 (overrulingUnited States v. Arnold, Schwinn & Co., 388 U.S. 365, 87 S.Ct. 1856, 18 L.Ed.2d 1249
(1967)); see also 433 U.S., at 58, n. 29, 97 S.Ct. 2549 (noting “that the advantages of vertical restrictions should not be limited to the
categories of new entrants and failing firms”). While the Court in a footnote in GTE Sylvania suggested that differences between vertical price
763-764, 104 S.Ct. 1464. In Monsanto, the Court required that antitrust plaintiffs alleging a § 1 price-fixing conspiracy must present evidence
tending to exclude the possibility a manufacturer and its distributors acted in an independent manner. Id., at 764, 104 S.Ct. 1464. Unlike
Justice Brennan’s concurrence, which rejected arguments that Dr. Miles should be overruled, see 465 U.S., at 769, 104 S.Ct. 1464, the Court
“decline[d] to reach the question” whether vertical agreements fixing resale prices always should be unlawful because neither party
suggested otherwise, id., at 761-762, n. 7, 104 S.Ct. 1464.In Business Electronics the Court further narrowed the scope of Dr. Miles. It held that
the per se rule applied only to specific agreements over price levels and not to an agreement between a manufacturer and a distributor to
terminate a price-cutting distributor. 485 U.S., at 726-727, 735-736, 108 S.Ct. 1515.
Most recently, in 1997, after examining the issue of vertical maximum price-fixing agreements in light of commentary and real experience, the
