(k) Burden of proof in disparate impact cases

(1)

(A) An unlawful employment practice based on disparate impact is established under this subchapter only if—

(i) a complaining party demonstrates that a respondent uses a particular employment practice that causes a disparate impact on the basis of race, color, religion, sex, or national origin and the respondent fails to demonstrate that the challenged practice is job related for the position in question and consistent with business necessity; or

(ii) the complaining party makes the demonstration described in subparagraph (C) with respect to an alternative employment practice and the respondent refuses to adopt such alternative employment practice.

(B)

(i) With respect to demonstrating that a particular employment practice causes a disparate impact as described in subparagraph (A)(i), the complaining party shall demonstrate that each particular challenged employment practice causes a disparate impact, except that if the complaining party can demonstrate to the court that the elements of a respondent's decisionmaking process are not capable of separation for analysis, the decisionmaking process may be analyzed as one employment practice.

(ii) If the respondent demonstrates that a specific employment practice does not cause the disparate impact, the respondent shall not be required to demonstrate that such practice is required by business necessity.

(C) The demonstration referred to by subparagraph (A)(ii) shall be in accordance with the law as it existed on June 4, 1989, with respect to the concept of "alternative employment practice".

(l) Prohibition of discriminatory use of test scores
It shall be an unlawful employment practice for a respondent, in connection with the selection or referral of applicants or candidates for employment or promotion, to adjust the scores of, use different cutoff scores for, or otherwise alter the results of, employment related tests on the basis of race, color, religion, sex, or national origin.

(m) Impermissible consideration of race, color, religion, sex, or national origin in employment practices
Except as otherwise provided in this subchapter, an unlawful employment practice is established when the complaining party demonstrates that race, color, religion, sex, or national origin was a motivating factor for any employment practice, even though other factors also motivated the practice.

(n) Resolution of challenges to employment practices implementing litigated or consent judgments or orders

(1)

(A) Notwithstanding any other provision of law, and except as provided in paragraph (2), an employment practice that implements and is within the scope of a litigated or consent judgment or order that resolves a claim of employment discrimination under the Constitution or Federal civil rights laws may not be challenged under the circumstances described in subparagraph (B).

(B) A practice described in subparagraph (A) may not be challenged in a claim under the Constitution or Federal civil rights laws—

(i) by a person who, prior to the entry of the judgment or order described in subparagraph (A), had—

(I) actual notice of the proposed judgment or order sufficient to apprise such person that such judgment or order might adversely affect the interests and legal rights of such person and that an opportunity was available to present objections to such judgment or order by a future date certain; and

(II) a reasonable opportunity to present objections to such judgment or order; or

(ii) by a person whose interests were adequately represented by another person who had previously challenged the judgment or order on the same legal grounds and with a similar factual situation, unless there has been an intervening change in law or fact.

(D) authorize or permit the denial to any person of the due process of law required by the Constitution.

(3) Any action not precluded under this subsection that challenges an employment consent judgment or order described in paragraph (1) shall be brought in the court, and if possible before the judge, that entered such judgment or order.
