April 29 (UPI) — The U.S. Supreme Court ruled against Louisiana’s newly drawn congressional map Wednesday, saying it relied too heavily on race.

The 6-3 decision eliminates one of the two predominantly Black congressional districts established by redistricting from the 2020 census.

Supporters of the redrawn map said it abided by Section 2 of the Voting Rights Act, which prevents lawmakers from packing racial minorities in a limited number of districts or spreading them across too many to diminish their voting power.

Justice Samuel Alito, writing for the majority, described Louisiana’s map as “unconstitutional gerrymander.”

“When §2 of the Act is properly interpreted, it imposes liability only when circumstances give rise to a strong inference that intentional discrimination occurred,” he wrote.

The ruling weakens the landmark Voting Rights Act passed in 1965 to limit racial discrimination in voting. The Supreme Court dealt the act a blow in 2013 when it struck a core provision providing oversight to states with a history of voting discrimination.

With the new ruling by the high court, Republican lawmakers will have an easier time redrawing state maps to more closely align with their party.

Justice Elena Kagan, one of the three dissenters, said such intentional discrimination is hard to prove and that Wednesday’s decision serves to “eviscerate the law.”

“Under the Court’s new view of Section 2, a State can, without legal consequence, systematically dilute minority citizens’ voting power,” she wrote.

It’s unlikely the Supreme Court’s ruling will have an impact on midterm elections later this year as early voting in congressional primaries begin May 16.
