Voting rights groups should be allowed to intervene as defendants in Louisiana's suit against the U.S. Election Assistance Commission through which the state seeks to require additional proof of citizenship, argued the League of Women Voters of Louisiana and others in a motion to intervene in the U.S. District Court for the Western District of Louisiana.

Nairne v. Landry poses a challenge under Section 2 of the Voting Rights Act of 1965 to Louisiana’s House and Senate legislative maps on behalf of plaintiff Black voters and Black voters across the state.

On June 24, 2024, a multi-faith group of nine Louisiana families with children in public schools filed a federal-court lawsuit in Louisiana, challenging House Bill No. 71 (“H.B. 71”), a new state law that requires every elementary, secondary, and postsecondary public school in the state to permanently display an official version of the Ten Commandments in every classroom. The families are represented by the ACLU, the ACLU of Louisiana, Americans United for Separation of Church and State, and the Freedom From Religion Foundation, with Simpson Thacher & Bartlett LLP serving as pro bono counsel. The complaint alleges that H.B. 71 violates both the separation of church and state, as protected by the Establishment Clause of the First Amendment, and the Free Exercise Clause of the First Amendment.

Robinson challenged the congressional map that Louisiana enacted after the 2020 Census. ACLU and partners represented Plaintiffs the Louisiana State Conference of the NAACP, Power Coalition for Equity and Justice, and several impacted voters, and argued that the enacted plan violated Section 2 of the Voting Rights Act. In June 2022, the district court found Louisiana's congressional map unlawfully denied Black voters a second district in which Black voters had an equal opportunity to elect their candidates of choice. After appeals, the legislature passed a new map containing two majority Black districts in January 2024.
