Moreover, the Attorney General precleared the proposed settlement. This preclearance approval of the proposed judgment is final and unreviewable.
Morris v. Gressette, 432 U.S. 491, 504–506, 97 S.Ct. 2411, 2420–21, 53 L.Ed.2d 506 (1977). In addition, if the proposed settlement is approved, the Attorney General is prepared to withdraw her objection to the legislatively enacted changes, rendering moot the question of Section 5 injunctive relief. Thus, the need for the three-judge court to review the provisions in the proposed settlement that relate to the plaintiffs' Section 5 waiver is contingent upon the review of the other provisions by the single-judge court. We agree with the plaintiffs, the defendants, and the United States (as
amicus curiae ), that in this unique case, if review by a three-judge court proves necessary, it can only take place after the single-judge court completes its consideration of the proposed settlement. Therefore, in light of the Attorney General's preclearance of the proposed settlement there is, at this time, no further role for the three-judge court under Section 5.
