Wise v. Missouri
In unprecedented fashion, the State of Missouri has redrawn the district lines used for electing members of Congress for a second time this decade. These new district lines are gerrymandered and will harm political representation for all Missourians, particularly Black residents in Kansas City, who have been divided along racial lines.

Missouri v. U.S. Department of Commerce
A coalition of civil rights and immigrant-rights organizations has moved to intervene as defendants in a lawsuit that threatens to dismantle the Constitution’s long-standing requirement that the decennial census count all people living in the United States. Missouri asks the court to exclude undocumented immigrants and people living in the country on temporary visas from the census count used to determine congressional representation—an unprecedented move that would upend more than two centuries of constitutional practice.

Reproductive Freedom
Comprehensive Health of Planned Parenthood Great Plains & Planned Parenthood Great Rivers v. Missouri
The ACLU, ACLU of Missouri, and Planned Parenthood Federation of America are representing Missouri’s two Planned Parenthood providers. Following the passage of Amendment 3, the Right to Reproductive Freedom Initiative, Comprehensive Health of Planned Parenthood Great Plains and Planned Parenthood Great Rivers, filed suit to restore abortion access in the state. The suit seeks to enjoin Missouri’s numerous abortion bans and countless burdensome, medically unnecessary restrictions on abortion that do not improve care or protect patient health. If the requested preliminary relief is granted, Planned Parenthood’s health centers would be able to begin providing abortion in Missouri once more — restoring access to this constitutionally protected health care.
