Desert Palace: The Same-Decision Defense Limited Relief, Not the Violation

Decision: Desert Palace, Inc. v. Costa, 539 U.S. 90 (2003).

Proof of a discriminatory motivating factor and proof of an employer’s same-decision defense answer different questions under the statutory framework discussed in Desert Palace, Inc. v. Costa, 539 U.S. 90 (2003). The 1991 Act separated establishment of a violation from limits on relief. That structure also helped the Court reject a special direct-evidence burden imposed only on the employee. For the actual trial record and instruction issue, see the companion evidence analysis.

The 1991 Act separated a violation from the available remedies

The opinion described two provisions added after Price Waterhouse. One establishes an unlawful employment practice when a listed protected trait is a motivating factor, even if other factors also played a role. The other addresses relief when an employer demonstrates it would have taken the same action without that impermissible factor. They must be read together rather than compressing every mixed-motive question into a single test. Desert Palace, 539 U.S. at 93–95.

The same-decision showing limited relief rather than erased the violation

Under the provision quoted in the opinion, the same-decision showing does not absolve the employer of the violation. It restricts available remedies: The court may grant specified declaratory or injunctive relief and qualifying fees and costs, but may not award damages or the listed admission, reinstatement, hiring, promotion, or payment orders. Those are statutory limits, not a promise of an automatic fee award or injunction. The defense itself requires proof, not just an employer’s assertion that another reason existed. Desert Palace, 539 U.S. at 94–95 and footnote 2.

The same word could not impose different proof rules on each side

Both the employee’s motivating-factor provision and the employer’s partial-defense provision use demonstrates. When pressed, the employer did not argue that it needed direct evidence to establish its own defense. The Court declined to assign the same term different meanings depending on whose rights were at issue absent a congressional indication to do so. That was an additional textual reason against imposing the special direct-evidence gateway on the employee. It did not shift every burden in every discrimination case. Desert Palace, 539 U.S. at 100–101.

The Court did not settle every pre-amendment question

The majority did not need to decide which Price Waterhouse opinion had controlled before the 1991 amendment. Justice O’Connor joined the unanimous decision and separately explained that Congress had adopted a new evidentiary rule. The Court affirmed the mixed-motive instruction under the amended Title VII provision before it; it did not resolve when, if ever, that amendment applies outside mixed-motive cases. Desert Palace, 539 U.S. at 94 footnote 1,98,102.

Key takeaways

• Identify whether the dispute concerns proof of a violation or limits on the remedy.
• Require a supported same-decision showing, not merely the existence of another asserted reason.
• Distinguish remedies the statute permits from those it forbids after the defense is established.
• Do not export this amended Title VII framework into another statute by analogy alone.
