The conservative majority of justices ruled that an electoral map could not be redrawn to create a second majority-Black district in Louisiana, breaking with the previous interpretation of Section 2 of the Voting Rights Act of 1965.

The court's decision in Louisiana v. Callais takes the teeth out of the Voting Rights Act, making it nearly impossible to draw new minority districts.

The decision will make it more difficult to successfully challenge legislative maps for diluting the voting power of racial minorities.
