Alabama Legislative Black Caucus v. Alabama, 575 U.S. 254 (2015), was a U.S. Supreme Court decision that overturned a previous decision by a federal district court upholding Alabama's 2012 redrawing of its electoral districts.
Following the 2010 census, Alabama's Republican-controlled legislature redrew state legislative district lines. The new plan maintained the same number of majority-minority Senate districts and added one more majority-minority House district. The existing African-American majority districts had lost population and new voters needed to be added to those districts, therefore the new plans focused on adding African-American voters to those districts to keep the same proportion of minority voters in each district. The Alabama Legislative Black Caucus and Alabama Democratic Conference challenged this on the grounds that it was an illegal racial gerrymander, banned under the Equal Protection Clause of the Fourteenth Amendment. The state said it was necessary to comply with Section 5 of the Voting Rights Act.
The case went before a three-judge panel in federal district court. The panel characterized the arguments of the Caucus and the Conference as challenging the Alabama redistricting as a whole, with the Conference additionally challenging four specific Senate districts: 7, 11, 22, and 26.
The panel held that the Caucus had standing for its claim, but dismissed the Conference's claims regarding both the state as a whole and the four districts. The Court further held that race was not the predominant factor for the redistricting as a whole or for the four districts because "the main priority of the Legislature was to comply with the constitutional mandate of one person, one vote". Finally, the panel held that, even if it was wrong and race was the predominant factor for the redistricting, the districts should still survive strict scrutiny because the act creating them was narrowly tailored to achieve the compelling state interest of complying with the VRA.
The Supreme Court, in a 5-4 opinion written by Justice Stephen Breyer, vacated the holdings of the District Court and remanded the case for further consideration in line with the decision:
Justice Antonin Scalia said the decision was "a sweeping holding that will have profound implications for the constitutional ideal of one person, one vote" which Alan Morrison said may be "the most overstated of Scalia's dissents".
After Alabama Legislative held that "a mechanically numerical view as to what counts as forbidden retrogression" would not survive strict scrutiny, Justice Anthony Kennedy held in Bethune-Hill v. Virginia State Board of Elections that a "mechanically numerical" racial target always triggers strict scrutiny even when the redistricting adhered to traditional principles such as compactness. Justice Kennedy noted that in some cases the legislature may have "good reasons" to believe that a racial target is needed to avoid retrogression.
