Comcast Corp. v. National Assn. of African-American Owned Media
The Supreme Court unanimously ruled that people suing for racial discrimination in contracting under a key Reconstruction-era civil rights law must prove race was the decisive, 'but-for' cause of their injury — not just that race played some role in the other party's decision.
The ruling rejects a more forgiving standard adopted by the Ninth Circuit and means these discrimination claims face the same demanding causation requirement from the moment a lawsuit is filed through any eventual trial.
How it got here: The district court dismissed ESN's complaint three times; the Ninth Circuit reversed using a lenient "some role" standard; the Supreme Court took the case to resolve a split among federal appeals courts.
The Case in Depth
What happened
Byron Allen, an African-American entrepreneur, owns Entertainment Studios Network (ESN), which operates seven television channels. For years, ESN tried to get Comcast, one of the country's largest cable companies, to carry its channels. Comcast refused, citing lack of programming demand, bandwidth constraints, and a preference for news and sports content ESN did not offer. ESN sued, claiming Comcast systematically discriminated against Black-owned media companies and that the stated business reasons were a cover for racial bias.
The question before the Court
Must a person suing under the federal civil rights law that guarantees equal rights to make contracts prove that race was the decisive cause of their harm — not merely that race played some role?
The Court's answer
Yes — a person suing under Section 1981 of the Civil Rights Act of 1866 must show that race was the decisive "but-for" cause of their injury, meaning they must demonstrate the other party would have acted differently had they been a different race. The Ninth Circuit was wrong to let claims go forward by showing only that race played "some role" in the defendant's decision.
The Court also rejected the argument that a more forgiving standard should apply early in a lawsuit when a complaint is being tested for legal sufficiency. Because the legal elements of any claim remain constant from filing through trial, the same but-for causation requirement governs both what a plaintiff must allege in a complaint and what they must ultimately prove at trial. Claims that pass a looser standard but cannot satisfy but-for causation are not viable under Section 1981.

Why it matters
Minority-owned businesses, media companies, and individuals who believe they were denied contracts because of their race face a higher hurdle to keep a lawsuit alive. They must allege — and eventually prove — that the other party would have acted differently had they been white, rather than simply showing race factored into the decision in some way.
What changes now
The case returns to the Ninth Circuit to evaluate, for the first time, whether ESN's complaint adequately alleges facts supporting a but-for causation theory. If the complaint does not clear that bar, the case may be dismissed again. Separately, the Court explicitly left open the question of whether Section 1981 protects only the final decision to enter a contract or also the entire contract-formation process — that question remains available for future consideration on remand.
What this does not decide
The Court explicitly did not decide whether Section 1981 protects only the final outcome of contract negotiations or also protects the entire contracting process — for example, whether racially discriminatory treatment during negotiations (not just a final refusal) can give rise to liability. That question was reserved for the lower courts on remand.
Concurrences and dissents
Concurrence in part — Justice Ginsburg
Justice Ginsburg joined the majority's holding that but-for causation is required, but wrote separately to push back on Comcast's argument — which the majority declined to resolve — that Section 1981 protects only the final decision to enter a contract. She argued the statute's text, its 1991 amendment, and its purpose make clear that it covers the entire contracting process: racially discriminatory barriers during negotiations, not just an outright contract refusal, can violate the law.
How the Court got there
The legal reasoning, step by step
- The Court began with two well-established background rules: first, that tort law — and federal anti-discrimination law — normally requires a plaintiff to prove 'but-for' causation (meaning the harm would not have happened without the defendant's wrongful conduct); and second, that a claim's legal elements stay constant throughout a lawsuit, so what must be proven at trial also must be plausibly alleged in the initial complaint.
- The text of Section 1981 points toward but-for causation. The statute guarantees people the 'same right to make contracts as is enjoyed by white citizens,' which naturally asks a counterfactual question: would the defendant have acted the same way if the plaintiff had been white? If yes, the plaintiff got the same right. If no, they didn't — and but-for causation is satisfied. Nothing in the text signals a different, easier test at the complaint stage.
- The broader structure of the Civil Rights Act of 1866 reinforces this. A neighboring provision created criminal liability for anyone who deprived someone of rights 'on account of' race or 'by reason of' their color — phrases courts have consistently read as requiring but-for causation. The same Act also explicitly incorporated the common law, which in 1866 generally required but-for causation as a precondition for any tort suit.
- The Court's own prior precedents confirm the point. When the Court first recognized a private right to sue under Section 1981, it described the statute as providing a remedy for discrimination 'on the basis of race' — language associated with but-for causation. The neighboring statute Section 1982 (covering property rights) has been read to require a 'because of race' showing, and the Court saw no basis to demand less from Section 1981 claims.
- The Court rejected ESN's effort to import the 'motivating factor' causation test from Title VII of the Civil Rights Act of 1964 — a test allowing plaintiffs to win if discrimination was one factor among several. The Court had twice before declined to carry that test over to other statutes. Crucially, when Congress added the motivating factor standard to Title VII in 1991, it simultaneously amended Section 1981 without adding any similar language, strongly suggesting Congress did not intend the same rule to apply.
- Finally, the Court dismissed ESN's reliance on the McDonnell Douglas burden-shifting framework — a tool from Title VII practice used at the summary judgment stage to evaluate indirect proof of discrimination. That framework arose in a context where but-for causation was undisputed; it does not address causation standards at all, and only shifts the burden of production (not the burden of proof) to the defendant. It cannot therefore excuse a complaint from alleging the essential elements of a claim.

Title VII's motivating factor test, first recognized in this case, was held inapplicable to Section 1981, which has a different text and history.
