Whether Title VI’s established private right of action under § 601 includes a private right to enforce disparate-impact regulations promulgated under § 602.
Holding
No. The private right of action to enforce § 601 does not itself extend to regulations that prohibit conduct § 601 permits.
Reasoning
The Court treated three propositions as settled or assumed: private individuals may sue under § 601; § 601 itself prohibits only intentional discrimination; and, for purposes of this case, agencies may validly issue § 602 regulations that prohibit disparate-impact discrimination. Because disparate-impact regulations reach conduct that is not independently forbidden by § 601, they cannot simply be enforced through the implied right of action for § 601.
Regulations that authoritatively interpret a statute ordinarily can be enforced through the statute’s private cause of action, because enforcing the regulation is effectively enforcing the statute as interpreted. But the disparate-impact regulations at issue do more than interpret § 601: they prohibit conduct that § 601, as previously construed, allows. A private right to enforce those regulations therefore had to arise, if at all, from § 602 itself.
Earlier Title VI decisions did not resolve the question. Cannon recognized a private action under Title VI and Title IX, but it involved assumed intentional discrimination. Guardians addressed available relief and the validity of disparate-impact regulations, but did not hold that private plaintiffs have a direct right to enforce those regulations. Lau had read § 601 itself to reach disparate impact, an interpretation later rejected by the Court’s intentional-discrimination precedents.
