Mississippi State Conference of the NAACP v. State Board of Election Commissioners
Mississippi has a growing Black population, which is already the largest Black population percentage of any state in the country. Yet. Black Mississippians continue to be significantly under-represented in the state legislature, as Mississippi’s latest districting maps fail to reflect the reality of the state’s changing demographics. During the 2022 redistricting process, the Mississippi legislature refused to create any new districts where Black voters have a chance to elect their preferred representative. The current district lines therefore dilute the voting power of Black Mississippians and continue to deprive them of political representation that is responsive to their needs and concerns, including severe disparities in education and healthcare.

Crystal Mason v. State of Texas
Crystal Mason thought she was performing her civic duty by filling out a provisional ballot in the 2016 election. She didn't know it would land her a five-year prison sentence, upending her family and the life she had built. At the time, Ms. Mason was on federal supervised release, a preliminary period of freedom for individuals who have served their full time of incarceration in federal prison. Ms. Mason didn’t know, and nobody told her, that the state considered her ineligible to vote while on supervised release. Because her name didn’t appear on voter rolls, she filed a provisional ballot, consistent with federal law. The state never counted her ballot but has still sought to send her to prison for an innocent mistake.

Western Native Voice v. Jacobsen
The American Civil Liberties Union, ACLU of Montana, Native American Rights Fund (NARF), and the Harvard Election Law Clinic challenged two Montana laws that hinder Native American participation in the state’s electoral process — HB 530, which prohibited paid third-party ballot collection; and HB 176, which repealed Election Day voter registration (EDR) in Montana. Together, these laws violate a number of provisions in the Montana Constitution: the right to vote, equal protection, free speech, and due process.

Hispanic Federation v. Byrd
Of all 50 states, Florida ranks 47th in percentage of its eligible citizens who are registered to vote. Yet, in May 2023, Florida Governor Ron DeSantis signed SB 7050, which bars any noncitizen — regardless of lawful residence status — from working or volunteering for third-party voter registration organizations (3PVROs) who register eligible Floridians to vote. In practice, the law imposes a $50,000 fine on a 3PVRO for each noncitizen who engages in voter-registration work on a 3PVRO’s behalf. This law would silence and put out of business countless community-based groups that rely on both citizens and noncitizens to help eligible voters in their communities participate in their democracy.

Sierra Club v. Trump — Challenge to Trump’s National Emergency Declaration to Construct a Border Wall
In February 2019, the ACLU filed a lawsuit challenging President Trump’s emergency powers declaration to secure funds to build a wall along the southern border. The lawsuit was filed on behalf of the Sierra Club and the Southern Border Communities Coalition. The lawsuit argues that the president is usurping Congress’s appropriations power and threatening the clearly defined separation of powers inscribed in the Constitution. On January 20, 2021, President Biden halted further border wall construction. Litigation in this and subsequent related challenges has been paused or deadlines extended while the ACLU’s clients and the Biden administration determine next steps.
