Babb v. Wilkie: Federal Personnel Actions Must Be Untainted by Age Bias

A federal employee can establish a violation of the Age Discrimination in Employment Act's federal-sector provision without proving that age was the but-for cause of the ultimate personnel outcome. The remedy available, however, still depends on whether age actually changed that outcome.

Procedural Posture

Noris Babb, a clinical pharmacist employed at a Department of Veterans Affairs medical center in Bay Pines, Florida, brought suit under 29 U.S.C. § 633a, the ADEA provision governing federal-sector employment. She challenged a series of personnel decisions affecting her promotion eligibility, training opportunities, work assignments, and pay. The district court granted summary judgment against her, and the Eleventh Circuit affirmed, both courts applying the private-sector but-for causation standard drawn from Gross v. FBL Financial Services, Inc., 557 U.S. 167 (2009). The Supreme Court granted certiorari to resolve whether that standard governs federal-sector claims. Babb v. Wilkie, 589 U.S. 399, 403–04 (2020).

The Statutory Text at Issue

The federal-sector provision commands that personnel actions affecting employees or applicants who are at least forty years old "shall be made free from any discrimination based on age." 29 U.S.C. § 633a(a). The Court, in an opinion by Justice Alito, focused on the phrase "free from any discrimination." That language, the Court explained, sets a standard for the process by which a personnel action is made, not merely for the ultimate outcome. Babb, 589 U.S. at 405–07. The private-sector provision, by contrast, makes it unlawful for an employer to take an adverse action "because of" age—language the Court had previously read to require but-for causation throughout. Id. at 406–07 (distinguishing Gross).

The Governing Standard

The Court's analysis proceeds in two distinct steps, and keeping them separate is essential to applying Babb correctly.

Step one — liability: Age must be the but-for cause of the discriminatory differential treatment embedded in the decisionmaking process. If age played any role in how the personnel action was evaluated or decided, the action was not made "free from" age discrimination, and a violation has occurred. Id. at 407–09. The plaintiff does not need to show that removing age from the equation would have changed the final result.

Step two — remedy: The scope of relief depends on causation in the traditional sense. Reinstatement, backpay, compensatory damages, and other make-whole remedies tied to the employment outcome require proof that the outcome itself would have been different absent the age discrimination. Where age infected the process but did not alter the result, the plaintiff may still obtain forward-looking relief such as an injunction requiring age-neutral procedures. Id. at 413–14.

In plain terms: the federal government must run a clean process. If it does not, a violation exists. But the size of the remedy scales with how much the tainted process actually hurt the employee.

Disposition

The Court reversed the Eleventh Circuit's judgment and remanded for further proceedings consistent with the lower liability threshold. Id. at 414–15. The Court did not itself resolve whether Babb was entitled to relief; it returned the case for application of the correct standard.

Limits of the Holding

Several boundaries deserve attention. First, Babb applies only to the federal-sector provision, 29 U.S.C. § 633a. Private-sector plaintiffs suing under 29 U.S.C. § 623 remain subject to the but-for standard of Gross. Second, the decision does not address Title VII or other anti-discrimination statutes; its reasoning is tethered to the specific text of § 633a(a). Third, not every age-related remark or stray comment automatically satisfies the standard; the plaintiff must still connect the age-based consideration to the challenged personnel action. Fourth, the two-step framework means that a plaintiff who proves a violation but cannot show outcome-level causation will obtain only limited relief—a point that shapes litigation strategy from the outset.

Practical Application

For federal employees and their counsel, Babb lowers the threshold for establishing liability but does not eliminate the need for careful record development. Evidence of how the decision was made—who evaluated the candidate, what criteria were applied, whether age-neutral procedures were followed—becomes as important as evidence of the final result. Practitioners should document the decisionmaking process, preserve communications among selecting officials, and assess separately what relief the record can support at the remedy stage.
