University of Tex. Southwestern Medical Center v. Nassar
The Supreme Court ruled that workers suing for retaliation under Title VII face a tougher standard than workers suing for discrimination based on race, sex, religion, or national origin: they must prove retaliation was the actual deciding reason for the adverse action, not just one factor among several.
The 5-4 decision splits Title VII's two main protections into different legal tracks, making it harder for employees to win retaliation claims even when they can show retaliation played some role in their employer's decision.
“Title VII retaliation claims must be proved according to traditional principles of but-for causation, not the lessened causation test stated in §2000e–2(m).”
The Court's core holding establishing the stricter causation standard for retaliation claims.
How it got here: A jury found for the doctor on both claims; the Fifth Circuit reversed the discrimination claim but affirmed the retaliation verdict, prompting the university's appeal.
The Case in Depth
What happened
A doctor of Middle Eastern descent worked as both a university faculty member and a hospital physician. He complained that a supervisor was biased against him because of his religion and ethnicity. After resigning his teaching post over the alleged harassment, another university official blocked the hospital from hiring him as a staff physician, allegedly to defend the supervisor's reputation. The doctor sued for both discrimination and retaliation.
The question before the Court
If a boss retaliates against a worker for complaining about discrimination, does the worker have to prove that retaliation was the actual deciding reason for the punishment?
The Court's answer
Yes — the Supreme Court ruled that employees bringing Title VII retaliation claims must prove that retaliation was the actual deciding reason for the employer's action, known as "but-for" causation. This is a tougher standard than the one used for race, sex, religion, or national-origin discrimination claims, where showing bias was merely "a motivating factor" is enough to win, even if other legitimate reasons also played a role.
The Court reasoned that Congress placed the lower motivating-factor standard only in the specific part of Title VII dealing with status-based discrimination, and pointedly left it out of the separate retaliation provision. Relying on similar reasoning from a recent age-discrimination case, the Court concluded that when a law says an employer acted "because of" a protected reason, that means the traditional, stricter but-for standard applies unless Congress says otherwise.

Why it matters
Employees who report discrimination and then face demotion, firing, or other punishment now must show that retaliation was the actual deciding reason for the employer's action, not merely a contributing factor. This makes retaliation claims harder to win at trial and easier to dismiss before trial, potentially discouraging some workers from reporting discrimination in the first place.
What changes now
The case goes back to the lower courts, where the retaliation claim must be reassessed under the stricter but-for causation standard rather than the more lenient motivating-factor standard the jury originally used. The university had asked the Court to enter judgment in its favor outright, but the Court left that determination to the courts closer to the trial record. The ruling is a final decision on the legal standard, not a temporary order.
What this does not decide
The Court did not decide whether the university should actually win the case under the correct standard — it left that fact-specific determination to the lower courts on remand. The ruling also does not address retaliation standards under other civil rights statutes like Title IX or the ADEA's private-sector provisions.
Concurrences and dissents
Dissent — Justice Ginsburg
Justice Ginsburg argued that the Court's decisions have long treated retaliation as a form of the very discrimination it responds to, so the same motivating-factor standard used for race, sex, and religion claims should apply to retaliation too. She criticized the majority for relying on Gross, a case about a different statute, and for creating confusing dual standards for trial judges and juries in cases involving both types of claims. She would have affirmed the lower court's ruling for the employee.
How the Court got there
The legal reasoning, step by step
- The Court began from the general rule in tort law that a plaintiff must show 'but-for' causation — that the harm would not have happened without the defendant's wrongful conduct — unless a statute says otherwise.
- The Court noted that for status-based discrimination claims (race, color, religion, sex, national origin), Congress lowered that bar in 1991 by adding a provision saying discrimination need only be 'a motivating factor,' even if other factors also played a role.
- Relying on its earlier decision in Gross v. FBL Financial Services interpreting similar 'because of' language in the federal age-discrimination law, the Court concluded that the word 'because' in Title VII's retaliation provision means the traditional but-for standard applies, since Congress used similar wording there.
- The Court found that the 1991 motivating-factor provision was written into the specific section of Title VII covering status-based discrimination only, and Congress did not extend that lower standard to the separate retaliation section, even though it could have.
- The Court also declined to apply the older, more employee-friendly framework from Price Waterhouse v. Hopkins to retaliation claims, reasoning that Congress's 1991 amendments had already replaced that framework for status-based claims and gave no signal it should carry over to retaliation.
- Because the retaliation provision required a stricter causation showing than the one the trial jury had been instructed to use, the Court concluded the case needed to be reevaluated under the correct but-for standard.
