The Court’s decision in this litigation underplays a dominant le VII theme. This Court has repeatedly emphasized that the statute “should not be read to thwart” efforts at voluntary compliance. Johnson, 480
U. S., at 630. Such compliance, we have explained, is “the preferred means of achieving [ le VII’s] objectives.” Firefighters v. Cleveland, 478 U. S. 501, 515 (1986). See also Kolstad v. American Dental Assn., 527 U. S. 526, 545 (1999) (
“Dissuading employers from [taking voluntaryaction] to prevent discrimination in the workplace is di-rectly contrary to the purposes underlying le VII.”); C29FR §1608.1(c).
The strong-basis-in-evidence standard,however, as barely described in general, and cavalierly applied in this case, makes voluntary compliance a hazardous venture.
As a result of today’s decision, an employer who discards a dubious selection process can anticipate costly disparate-treatment litigation in which its chances for success—even for surviving a summary-judgment motion—are highly problematic. Concern about exposure to disparate-impact liability, however well grounded, is insufficient to insulate an employer from attack.
Instead, the employer must make a “strong” showing that (1) its selection method was“not job related and consistent with business necessity,” or
(2) that it refused to adopt “an equally valid, less-discriminatory alternative.” Ante, at 28. It is hard to see how these requirements differ from demanding that an employer establish “a provable, actual violation” against itself .
