Dissent in Matsushita Electric Industrial Co. v. Zenith Radio Corp.
475 U.S. 574 (1986) (1986) · Supreme Court of the United States
Matsushita, the third case in the summary judgment trilogy, held that when the nonmovant's theory of the case is economically implausible, the nonmovant must present more persuasive evidence to survive summary judgment. The decision established that courts should consider the plausibility of the nonmovant's theory when evaluating whether a genuine dispute of material fact exists.
What was the dissent in Matsushita Electric Industrial Co. v. Zenith Radio Corp.?
Justice White dissented, joined by Justices Brennan, Blackmun, and Stevens. He argued that the majority improperly weighed the evidence and made credibility determinations at the summary judgment stage, which should be reserved for the jury. He contended that the evidence, viewed in the light most favorable to the plaintiffs, raised genuine issues of material fact about the existence of a conspiracy.

Case Overview
Facts
American electronics manufacturers Zenith Radio and National Union Electric sued 21 Japanese electronics corporations, alleging a decades-long conspiracy to drive American firms from the market by charging artificially low prices in the United States (predatory pricing) while maintaining high prices in Japan. The case involved massive discovery over more than eight years. The Japanese defendants moved for summary judgment, arguing that the alleged conspiracy made no economic sense because predatory pricing requires sustained losses with no guarantee of recoupment.
Majority Holding
The Supreme Court held that the nonmovant's evidence was insufficient to defeat summary judgment. When the nonmovant's theory of the case is implausible, it must come forward with more persuasive evidence than would otherwise be necessary to show that there is a genuine issue for trial. Conduct that is as consistent with permissible competition as with illegal conspiracy does not, standing alone, support an inference of conspiracy.
Majority Reasoning
Justice Powell's majority opinion held that if the factual context renders the nonmovant's claim implausible, the nonmovant must come forward with more persuasive evidence to support its theory. A predatory pricing conspiracy lasting over twenty years, during which the conspirators sustained massive losses, was economically implausible because rational businesses would not sustain long-term losses without a strong prospect of recoupment. The plaintiffs' evidence — largely showing parallel pricing and ambiguous business documents — was equally consistent with independent competitive behavior. The Court emphasized that antitrust law should not deter vigorous competition, and allowing meritless conspiracy claims to proceed to trial based on ambiguous evidence would chill procompetitive conduct.
The Dissenting Opinion
Justice White dissented, joined by Justices Brennan, Blackmun, and Stevens. He argued that the majority improperly weighed the evidence and made credibility determinations at the summary judgment stage, which should be reserved for the jury. He contended that the evidence, viewed in the light most favorable to the plaintiffs, raised genuine issues of material fact about the existence of a conspiracy.
Key Quotes
“If the factual context renders respondents' claim implausible — if the claim is one that simply makes no economic sense — respondents must come forward with more persuasive evidence to support their claim than would otherwise be necessary.”
“Conduct as consistent with permissible competition as with illegal conspiracy does not, standing alone, support an inference of antitrust conspiracy.”
“Antitrust law limits the range of permissible inferences from ambiguous evidence in a § 1 case.”
Impact and Legacy
Matsushita strengthened the summary judgment device by allowing courts to consider the plausibility of the nonmovant's theory when evaluating evidence. The decision, combined with Celotex and Anderson, signaled the Court's willingness to use summary judgment to screen out implausible claims before trial. Matsushita's approach later influenced the plausibility standard adopted for pleading in Twombly, which explicitly cited Matsushita in requiring plausible grounds for a conspiracy claim.
Exam Relevance
Matsushita is tested as part of the summary judgment trilogy, particularly in the context of complex antitrust or conspiracy claims. Students should understand how the plausibility of a legal theory affects the summary judgment analysis and how Matsushita's reasoning connects to Twombly's plausibility pleading standard. Exam questions may ask whether ambiguous evidence is sufficient to create a genuine dispute when the underlying theory is implausible.
Study Tips
- Understand Matsushita's key contribution: when the nonmovant's theory is implausible, more persuasive evidence is required to defeat summary judgment.
- Connect Matsushita to Twombly — both cases address the problem of ambiguous evidence that is equally consistent with lawful and unlawful conduct.
- Know the dissent's criticism: the majority engaged in improper fact-finding and evidence-weighing at the summary judgment stage.
- Apply all three trilogy cases together on exams: Celotex (moving party's burden), Anderson (genuine dispute standard), Matsushita (plausibility of theory affects evidentiary standard).

More Civil Procedure Dissents
Pennoyer v. Neff
95 U.S. 714 (1878) (1878)
Justice Hunt dissented, arguing that the Oregon statute authorizing service by publication was a valid exercise of state legislative power and that the procedure followed was sufficient to confer jurisdiction over nonresidents with property in the state.
World-Wide Volkswagen Corp. v. Woodson
444 U.S. 286 (1980) (1980)
Justice Brennan dissented, arguing that the majority's approach was too restrictive and that the defendants placed their products into the stream of commerce knowing they might reach any state. He contended that when a product causes injury in a forum state, the interests of the state and the injured plaintiff should weigh heavily in the jurisdictional analysis.
Daimler AG v. Bauman
571 U.S. 117 (2014) (2014)
Justice Sotomayor concurred in the judgment but disagreed with the majority's 'at home' test. She argued that the majority's approach was too restrictive and that the Court should have resolved the case by holding that the exercise of jurisdiction would be unreasonable, rather than by narrowing the general jurisdiction test itself.
Bristol-Myers Squibb Co. v. Superior Court of California
582 U.S. 255 (2017) (2017)
Justice Sotomayor dissented, arguing that BMS's extensive activities in California, combined with its nationwide marketing of Plavix, created sufficient contacts for specific jurisdiction. She warned that the decision would impede the efficient resolution of mass tort litigation by preventing plaintiffs from consolidating their claims in a single forum.
Ford Motor Co. v. Montana Eighth Judicial District Court
592 U.S. 351 (2021) (2021)
Justice Gorsuch concurred in the judgment but wrote separately, joined by Justice Thomas, questioning the majority's reliance on the 'relate to' language. He argued that the majority's approach was vague and suggested that the original understanding of the Fourteenth Amendment might support a broader basis for jurisdiction. Justice Barrett took no part in the decision.
Erie Railroad Co. v. Tompkins
304 U.S. 64 (1938) (1938)
Justice Butler dissented, joined by Justice McReynolds, arguing that the question of overruling Swift had not been briefed or argued by the parties and that the doctrine of stare decisis counseled against overturning nearly a century of precedent without full adversarial consideration.
