28 CFR 51.55: Consistency with constitutional and statutory requirements.

(a) Consideration in general. In making a determination under section 5, the Attorney General will consider whether the change neither has the purpose nor will have the effect of denying or abridging the right to vote on account of race, color, or membership in a language minority group in light of, and with particular attention being given to, the requirements of the 14th, 15th, and 24th Amendments to the Constitution, 42 U.S.C. 1971(a) and (b), sections 2, 4(a), 4(f)(2), 4(f)(4), 201, 203(c), and 208 of the Act, and other constitutional and statutory provisions designed to safeguard the right to vote from denial or abridgment on account of race, color, or membership in a language minority group.

(b) Section 2. Preclearance under section 5 of a voting change will not preclude any legal action under section 2 by the Attorney General if implementation of the change demonstrates that such action is appropriate.
