This morning the Supreme Court heard oral argument in the case of Northwest Austin Municipal Utility District Number One v. Eric Holder, a case involving a small municipal district in Austin, Texas seeking to invalidate a key provision of the Voting Rights Act of 1965 - one of the most important civil rights laws in American history.

With the passage of the Voting Rights Act, Congress finally acted to prevent discriminatory tactics designed to prevent minorities from exercising their fundamental right to vote. Section 5, in particular, is the centerpiece of the Act, and requires certain covered jurisdictions where voting discrimination has been the most flagrant to seek a preclearance from the Justice Department or a three-judge panel of the federal court in DC for any voting related changes. According to the statute, preclearance will be given as long as the proposed change does not have the purpose or the effect of denying or infringing on the right to vote because of one’s race or color.

In this case, the party seeking to invalidate Section 5 is a municipal utility district in Travis County, Texas, that conducts elections to select the members of its board of directors. Because the State of Texas is a covered jurisdiction, the district is subject to the preclearance requirements of Section 5, and sought relief under the Act’s bailout provision in federal court in the days following the reauthorization of the Act in 2006. Alternatively, the utility district sought to invalidate the provision if it could not bailout from its requirements. It failed on both counts in the courts below.

Today’s arguments confirm that Justice Kennedy again holds the deciding vote on whether the Court will weaken or invalidate a provision upheld by the very same Court four times in the past.

To those who argue that Section 5 is no longer needed because racial discrimination no longer exists, as evidenced by the election of the country’s first African American president, look at the facts. Because of Section 5’s sunset provisions, Congress was required to re-examine whether the statute is needed and last conducted an examination of this type in 2006. The House and Senate Judiciary Committees held a combined 21 hearings over 10 months and received testimony from over 90 witnesses, including state and federal officials, experts and private citizens. And although they concluded that significant progress had been made, they recognized that “[d]iscrimination today is more subtle than the visible methods used in 1965” and concluded that discrimination continues to result in “a diminishing of the minority community’s ability to fully participate in the electoral process and to elect their preferred candidates of choice.” Congress voted 390-33 in the House and 98-0 in the Senate that, among other things, Section 5 was still necessary.

We hope that Justice Kennedy will remember the extensive record finding Congress performed in 2006 and remember his words earlier this year when he wrote in Bartlett v. Strickland, “Still, racial discrimination and racially polarized voting are not ancient history. Much remains to be done to ensure that citizens of all races have equal opportunity to share and participate in our democratic processes and traditions. . .”
