The legal dispute is focused on who is allowed to sue to try to enforce key provisions under Section 2 of the landmark civil rights law, which was first passed in 1965.

Private individuals and groups, who did not represent the U.S. government, have for decades brought the majority of Section 2 cases to court. Those cases have challenged the redrawing of voting maps and other steps in the elections process with claims that the voting power of people of color has been minimized.

U.S. District Judge Lee Rudofsky, an appointee of former President Donald Trump, ruled in February 2022, however, that only the head of the Justice Department, the U.S. attorney general, can bring Section 2 lawsuits and dismissed an Arkansas redistricting case brought by advocacy groups representing Black voters in the state.
