Indiana NAACP and League of Women Voters of Indiana v. Lawson

The Brennan Center filed a lawsuit against the State of Indiana on behalf of the Indiana NAACP and the League of Women Voters of Indiana, challenging Senate Enrolled Act 442 (SEA 442), a law enacted in 2017 that violated the National Voter Registration Act’s protections against wrongful voter removals. In March 2020, Indiana enacted Senate Enrolled Act 334 to amend SEA 442, but provisions of the amended law continue to violate the NVRA.

On August 27, 2019, the 7th Circuit Court of Appeals affirmed the preliminary injunction ruling from last year, which blocked a controversial purge law that could have removed voters without notice. 

At issue in the suit are Senate Enrolled Act 442 and Senate Enrolled Act 334, Indiana laws that violate the National Voter Registration Act (NVRA) by eliminating requirements to provide a notice and waiting period for a group of voters flagged as having moved out of state. On August 23, 2017, plaintiffs Indiana NAACP and the League of Women Voters of Indiana filed suit seeking reinstatement of federal protections eliminated by SEA 442. In June of 2018, a federal court blocked enforcement of SEA 442. The defendants later appealed the preliminary injunction order to the 7th Circuit Court of Appeals, and the court heard oral argument on the appeal on January 14, 2019. On August 27, 2019, the 7th Circuit Court of Appeals affirmed the preliminary injunction.

On March 20, 2020, Governor Eric Holcomb signed Senate Enrolled Act 334 (SEA 334), which amended SEA 442. However, SEA 334 still expressly allows purges without direct contact from the voter, and without the notice and waiting period required by the NVRA.

On July 1, 2020, the NAACP and LWV-IN filed a motion for summary judgment, seeking a permanent injunction prohibiting Defendants’ implementation of certain provisions of SEA 334 and prohibiting Defendants from otherwise removing any Indiana registrant from the list of eligible voters because of a change in residence absent: (1) a request or confirmation directly from the voter that the voter is ineligible or does not wish to be registered; or (2) the NVRA-prescribed process of (a) notifying the voter, (b) giving the voter an opportunity to respond, and (c) then waiting two inactive federal election cycles.


Voter purges, the process by which states remove the names of supposedly ineligible individuals from registration lists, can sweep in eligible voters if done improperly. While responsible voter list maintenance is necessary and appropriate, largescale voter purges without safeguards can result in wrongful disenfranchisement. Necessary safeguards include compliance with the National Voter Registration Act of 1993, also known as motor-voter. Among other requirements, the NVRA provides that before voters can be removed because of change of residence, they must either confirm that they have moved or receive a mailed notice that they are going to be removed, fail to respond, and fail to vote in two consecutive federal elections. Voter purges also risk removing eligible voters if election officials use bad data (or use data in a sloppy manner) in their attempt to identify ineligible voters.

SEA 442 relied on the now-defunct Crosscheck program to identify ineligible voters, even though Crosscheck had been proven to be unreliable as the sole basis for identifying and removing voters who may have moved. When Crosscheck, which was administered by the Kansas Secretary of State, was used for a 2013 Virginia voter purge, 40,000 registered voters were removed from the rolls prior to a statewide election, even though local election officials found error rates as high as 17 percent. Moreover, according to a 2016 analysis, minorities were more likely than white voters to be flagged for removal in Crosscheck. 

SEA 334 voided Indiana’s agreement with the Kansas Secretary of State and mandated Indiana’s withdrawal from Crosscheck. However, in Crosscheck’s place, SEA 334 established the Indiana Data Enhancement Association (“IDEA”), an organization functionally identical to Crosscheck that receives member states’ voter lists and returns purported matches.
