Incorrect headline here. One district out of the 12 in question is deemed legitimate, the other 11 are not "struck down" but remanded back to district court for further study.
Not quite. 1/12 was previously ruled unconstitutional by the district court. The Supreme Court upheld that part of the ruling and ordered the district court to revisit the other 11/12 because it applied the wrong standard when it found them constitutional.
From SCOTUS opinion: "As to the remaining district, District 75, the [district] court found that race did predominate, but that the lines were constitutional because the legislature’s use of race was narrowly tailored to a compelling state interest. ... Held: .... [T]he record here supports the State’s conclusion that this was an instance where a 55% BVAP was necessary for black voters
to have a functional working majority."
