“Coverage today is based on decades-old data and eradicated practices. The formula captures States by reference to literacy tests and low voter registration and turnout in the 1960s and early 1970s. But such tests have been banned nationwide for over 40 years. §6, 84Stat. 315; §102, 89Stat. 400. And voter registration and turnout numbers in the covered States have risen dramatically in the years since. H. R. Rep. No. 109–478, at 12. Racial disparity in those numbers was compelling evidence justifying the preclearance remedy and the coverage formula. See, e.g., Katzenbach, supra, at 313, 329–330. There is no longer such a disparity.
In 1965, the States could be divided into two groups: those with a recent history of voting tests and low voter registration and turnout, and those without those characteristics. Congress based its coverage formula on that distinction. Today the Nation is no longer divided along those lines, yet the Voting Rights Act continues to treat it as if it were.
The Government’s defense of the formula is limited. First, the Government contends that the formula is “reverse-engineered”: Congress identified the jurisdictions to be covered and then came up with criteria to describe them. Brief for Federal Respondent 48–49. Under that reasoning, there need not be any logical relationship be-tween the criteria in the formula and the reason for coverage; all that is necessary is that the formula happen to capture the jurisdictions Congress wanted to single out.
The Government suggests that Katzenbach sanctioned such an approach, but the analysis in Katzenbach was quite different. Katzenbach reasoned that the coverage formula was rational because the “formula . . . was relevant to the problem”: “Tests and devices are relevant to voting discrimination because of their long history as a tool for perpetrating the evil; a low voting rate is pertinent for the obvious reason that widespread disenfranchisement must inevitably affect the number of actual voters.” 383 U. S., at 329, 330.
Here, by contrast, the Government’s reverse- engineering argument does not even attempt to demonstrate the continued relevance of the formula to the problem it targets. And in the context of a decision as significant as this one—subjecting a disfavored subset of States to “extraordinary legislation otherwise unfamiliar to our federal system,” Northwest Austin, supra, at 211—that failure to establish even relevance is fatal.
The Government falls back to the argument that because the formula was relevant in 1965, its continued use is permissible so long as any discrimination remains in the States Congress identified back then—regardless of how that discrimination compares to discrimination in States unburdened by coverage. Brief for Federal Respondent 49–50. This argument does not look to “current political conditions,” Northwest Austin, supra, at 203, but instead relies on a comparison between the States in 1965. That comparison reflected the different histories of the North and South. It was in the South that slavery was upheld by law until uprooted by the Civil War, that the reign of Jim Crow denied African-Americans the most basic freedoms, and that state and local governments worked tirelessly to disenfranchise citizens on the basis of race. The Court invoked that history—rightly so—in sustaining the disparate coverage of the Voting Rights Act in 1966. See Katzenbach, supra, at 308 (“The constitutional propriety of the Voting Rights Act of 1965 must be judged with reference to the historical experience which it reflects.”).
But history did not end in 1965. By the time the Act was reauthorized in 2006, there had been 40 more years of it. In assessing the “current need[ ]” for a preclearance system that treats States differently from one another today, that history cannot be ignored. During that time, largely because of the Voting Rights Act, voting tests were abolished, disparities in voter registration and turnout due to race were erased, and African-Americans attained political office in record numbers. And yet the coverage formula that Congress reauthorized in 2006 ignores these developments, keeping the focus on decades-old data rel-evant to decades-old problems, rather than current data reflecting current needs.”
“The situation Congress faced in 2006, when it took up reauthorization of the coverage formula, was not the same. By then, the formula had been in effect for many years, and all of the jurisdictions covered by it were “familiar to Congress by name.” Id., at 328. The question before Congress: Was there still a sufficient basis to support continued application of the preclearance remedy in each of those already-identified places? There was at that point no chance that the formula might inadvertently sweep in new areas that were not the subject of congressional findings. And Congress could determine from the record whether the jurisdictions captured by the coverage for-mula still belonged under the preclearance regime. If they did, there was no need to alter the formula. That is why the Court, in addressing prior reauthorizations of the VRA, did not question the continuing “relevance” of the formula.
Consider once again the components of the record before Congress in 2006. The coverage provision identified a known list of places with an undisputed history of serious problems with racial discrimination in voting. Recent evidence relating to Alabama and its counties was there for all to see. Multiple Supreme Court decisions had upheld the coverage provision, most recently in 1999. There was extensive evidence that, due to the preclearance mechanism, conditions in the covered jurisdictions had notably improved. And there was evidence that preclearance was still having a substantial real-world effect, having stopped hundreds of discriminatory voting changes in the covered jurisdictions since the last reauthorization. In addition, there was evidence that racial polarization in voting was higher in covered jurisdictions than elsewhere, increasing the vulnerability of minority citizens in those jurisdictions. And countless witnesses, reports, and case studies documented continuing problems with voting dis-crimination in those jurisdictions. In light of this rec- ord, Congress had more than a reasonable basis to conclude that the existing coverage formula was not out of sync with conditions on the ground in covered areas. And certainly Shelby County was no candidate for release through the mechanism Congress provided. See supra, at 22–23, 26–28.
The Court holds §4(b) invalid on the ground that it is “irrational to base coverage on the use of voting tests 40 years ago, when such tests have been illegal since that time.” Ante, at 23. But the Court disregards what Congress set about to do in enacting the VRA. That extraordinary legislation scarcely stopped at the particular tests and devices that happened to exist in 1965. The grand aim of the Act is to secure to all in our polity equal citizenship stature, a voice in our democracy undiluted by race. As the record for the 2006 reauthorization makes abundantly clear, second-generation barriers to minority voting rights have emerged in the covered jurisdictions as attempted substitutes for the first-generation barriers that originally triggered preclearance in those jurisdictions. See supra, at 5–6, 8, 15–17.
The sad irony of today’s decision lies in its utter failure to grasp why the VRA has proven effective. The Court appears to believe that the VRA’s success in eliminating the specific devices extant in 1965 means that preclearance is no longer needed. Ante, at 21–22, 23–24. With that belief, and the argument derived from it, history repeats itself. The same assumption—that the problem could be solved when particular methods of voting discrimination are identified and eliminated—was indulged and proved wrong repeatedly prior to the VRA’s enactment. Unlike prior statutes, which singled out particular tests or devices, the VRA is grounded in Congress’ recognition of the “variety and persistence” of measures designed to impair minority voting rights. Katzenbach, 383 U. S., at 311; supra, at 2. In truth, the evolution of voting discrimination into more subtle second-generation barriers is powerful evidence that a remedy as effective as preclearance remains vital to protect minority voting rights and prevent backsliding.
Beyond question, the VRA is no ordinary legislation. It is extraordinary because Congress embarked on a mission long delayed and of extraordinary importance: to realize the purpose and promise of the Fifteenth Amendment. For a half century, a concerted effort has been made to end racial discrimination in voting. Thanks to the Voting Rights Act, progress once the subject of a dream has been achieved and continues to be made.”
