Race in voting maps

Abbott v. Perez

Updated Oct 22, 2026

In brief

Texas largely won, although State House District 90 remained an unconstitutional racial gerrymander.

Where it stands
Decided

Decided 5-4 · June 25, 2018 · Opinion by Justice Thomas

What it’s about
The Court held that it had jurisdiction to review the lower court’s redistricting orders and that the lower court wrongly required Texas to disprove discriminatory intent when the 2013 Legislature adopted plans based largely on court-drawn interim maps.
Who it affects
The decision largely preserved Texas's 2013 congressional and state House maps. Voters in the affected districts could keep those boundaries, except that House District 90 remained unconstitutional.

What it's about

The Court reversed the rulings invalidating several districts under the Voting Rights Act, but upheld the finding that State House District 90 was an unconstitutional racial gerrymander; Texas largely prevailed.

The case addressed when a state may adopt court-drawn temporary voting maps and how courts assess claims of intentional racial discrimination in redistricting.

Question presented

1. Whether the district court issued an appealable interlocutory injunction when it invalidated Texas' duly enacted redistricting plan and ordered the parties to appear at a remedial hearing to redraw state congressional districts unless the Governor called a special legislative session to redraw the congressional map within three days. 2. Whether the Texas Legislature acted with an unlawful purpose when it enacted a redistricting plan originally imposed by the district court to remedy any potential constitutional and statutory defects in a prior legislative plan that was repealed without ever having taken effect. 3. Whether the Texas Legislature engaged in intentional vote dilution when it adopted Congressional District 27 in 2013 after the district court found, in 2012, that CD27 did not support a plausible claim of racially discriminatory purpose and did not dilute Hispanic voting strength because it was not possible to create an additional Hispanic opportunity district in the region;? 4. Whether the Legislature engaged in racial gerrymandering in Congressional District 35 when it simply adopted the district unchanged as part of the court-ordered remedial plan.

What the Court decided

Holding

The Texas court erred in requiring the State to show that the 2013 Legislature purged the “taint” that the court attributed to the defunct and never-used plans enacted by a prior legislature in 2011. Once the Texas court’s intent finding is reversed, there remain only four districts that were invalidated on alternative grounds. The Texas court’s holding as to the three districts in which it relied on §2’s “effects” test are reversed, but its holding that HD90 is a racial gerrymander is affirmed. No. 17–586, 274 F. Supp. 3d 624, reversed
