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.
