NICHOLAS O. STEPHANOPOULOS Disparate Impact, Unified Law abstract. The last decade has seen the largest wave of franchise restrictions since the dark days of Jim Crow. In response to this array of limits, lower courts have recently converged on a two-part test under section 2 of the Voting Rights Act. This test asks if an electoral practice (1) causes a disparate racial impact (2) through its interaction with social and historical discrimina- tion. Unfortunately, the apparent judicial consensus is only skin-deep. Courts bitterly disagree over basic questions like whether the test applies to specific policies or systems of election admin- istration; whether it is violated by all, or only substantial, disparities; and whether disparities refer to citizens’ compliance with a requirement or to their turnout at the polls. The test also sits on thin constitutional ice. It comes close to finding fault whenever a measure produces a disparate impact and so coexists uneasily with Fourteenth Amendment norms about colorblindness and Congress’s remedial authority. The section 2 status quo, then, is untenable. To fix it, this Article proposes to look beyond election law to the statutes that govern disparate impact liability in employment law, housing law, and other areas. Under these statutes, breaches are not determined using the two-part section 2 test. Instead, courts employ a burden-shifting framework that first requires the plaintiff to prove that a particular practice causes a significant racial disparity and then gives the defendant the op- portunity to show that the practice is necessary to achieve a substantial interest. This framework, the Article argues, would answer the questions that have vexed courts in section 2 cases. The frame- work would also bolster section 2’s constitutionality by allowing jurisdictions to justify their chal- lenged policies. Accordingly, the solution to section 2’s woes would not require any leaps of doc- trinal innovation. It would only take the unification of disparate impact law. author.

(This is not a far-fetched scenario; more voting restrictions have been enacted over the last decade than at any point since the end of Jim Crow.1) Suppose also that the state’s new law has a disparate racial impact: that it affects a higher proportion of minority than nonminority citizens. (This too is a plausible assumption; minority citizens are less affluent, on average, and so more disadvantaged by measures that increase the resources required for voting.2) Courts and commentators agree that, standing alone, this racial disparity does not breach section 2 of the Voting Rights Act (VRA), the key statutory pro- vision banning racial discrimination in voting.3 In the oft-repeated words of one district court, “a plaintiff must demonstrate something more than dispropor- tionate impact to establish a Section 2 violation.”4 Or as a prominent VRA liti- gator has put it, “Section 2 plaintiffs [must] establish . that the disparate im- pact of a challenged vote denial practice is not merely a statistical accident.”5 Now imagine that a litigant does come up with “something more” than a na- ked racial disparity—specifically, evidence that the disparity is caused by the law’s interaction with historical and ongoing patterns of racial discrimination. In a photo ID case, this evidence might show that minority citizens are poorer than nonminority citizens; that their relative poverty is the product of discrimi- nation; that because they are poorer, they are less likely to own cars; and that because they drive less, they are also less likely to have driver’s licenses. In an early-voting case, the causal chain might run from discrimination to worse job 1. See, e.g., New Voting Restrictions in America, BRENNAN CTR. FOR JUST.

It is even more important now that the VRA’s other pillar, section 5, has been neutered. See Shelby County v. Holder, 133 S. Ct. 2612 (2013) (striking down the coverage formula used to determine which jurisdictions would be subject to section 5’s preclearance requirement). 4. Brown v. Detzner, 895 F.

Given this kind of record, the emerging judicial consensus is that section 2 is violated. In the Fourth, Fifth, Sixth, Seventh, and Ninth Circuits—though not necessarily in the Supreme Court, which has yet to decide a vote denial case un- der the VRA—liability ensues if an electoral policy (1) has a disparate racial im- pact that (2) is attributable to the policy’s interaction with discriminatory con- ditions.6 And properly so, according to many scholars. To cite a high-profile pair, Sam Issacharoff lauds the courts’ two-part test as a “breakthrough,”7 while Pam Karlan extols its capacity “to disrupt politics as usual in the service of full civic inclusion for long-excluded minority citizens.”8 But there is a problem with construing section 2 in this fashion. Section 2 is a disparate impact provision—a law that imposes liability on the basis of dis- criminatory effect, not invidious intent. Section 2, however, is not the only such provision. Rather, disparate impact theories are also recognized by Title VII of the Civil Rights Act, by the Fair Housing Act (FHA), and by several more stat- utes.9 In these other areas, a violation is not established simply because a policy interacts with discriminatory conditions to produce a disparate impact. Instead, courts follow a well-developed framework under which (1) the plaintiff must prove that a particular practice causes a significant discriminatory effect; (2) the defendant next has the opportunity to show that the practice is necessary to achieve a substantial interest; and (3) the plaintiff may then demonstrate that this interest could be attained in a different, less discriminatory way. The emerg- ing consensus in the vote denial context thus threatens to drive a wedge between section 2 and every other disparate impact provision. It risks turning section 2 into a lonely island in the disparate impact sea. My aim in this Article, then, is to resist this consensus—to urge consistency rather than variety in disparate impact law and to bring vote denial cases into the familiar disparate impact fold. To state my thesis another way: to date, courts have focused on the explanations for racial disparities in voting, especially the ex- tent to which they are intertwined with past and present discrimination. In my view, though, courts should scrutinize the interests that allegedly justify these 6. See Dale E.
