What it's about

The Court emphasized that plaintiffs must disentangle race from politics when the two are correlated and generally must provide an alternative map to prove racial predominance.

The case shows the difficult line between political gerrymandering (drawing districts to help a party) and racial gerrymandering (drawing them mainly around race) when race and party choice overlap.

Question presented

Does the South Carolina legislature’s redistricting map, which has the effect of moving tens of thousands of Black voters to a different district, constitute an impermissible racial gerrymander, even if the legislators’ purported intent was merely a political gerrymander?

What the Court decided

Holding

1. The District Court’s finding that race predominated in the design of District I in the Enacted Plan was clearly erroneous. 2. Because the same findings of fact and reasoning that guided the court’s racial-gerrymandering analysis also guided the analysis of the Challengers’ independent vote-dilution claim, that conclusion also cannot stand. The District Court also erred in conflating the two claims. A plaintiff pressing a vote-dilution claim cannot prevail simply by showing that race played a predominant role in the districting process, but rather must show that the State “enacted a particular voting scheme as a purposeful device to minimize or cancel out the voting potential of racial or ethnic minorities.” Miller , 515 U. S., at 911. Reversed in part and remanded in part.

From the opinions

“This voting case, as the Court acknowledges, turns on a quintessential factual dispute: Did South Carolina rely on racial data to reconfigure the State’s Congressional District 1?”

— Justice Kagan(dissent)

What's next

The federal district court must reconsider the minority-voting-power claim separately from the claim that race drove the district lines. The challengers must prove that South Carolina enacted a particular voting scheme as a purposeful device to minimize or cancel out minority voting power.

Why it matters

The separate vote-dilution claim (a claim that a map weakens minority voting power) was sent back to that court (remanded in part), where challengers must show South Carolina enacted a particular voting scheme as a purposeful device to minimize or cancel out minority voting power.

It overturned the federal district court’s finding that race was the main factor in designing District 1. The Court said that finding was clearly wrong.
What remains unresolved after the ruling?
The separate claim that the map weakened minority voting power was sent back to the federal district court for another look (remanded in part). The court must analyze it separately.
