What it's about

The Supreme Court ruled that federal courts cannot decide partisan-gerrymandering claims, wiped out the lower court’s ruling (vacated it), and sent the case back (remanded it).

The federal district court had ruled that the 2016 map was unconstitutional as a partisan gerrymander; North Carolina lawmakers appealed.

The central dispute was when political mapmaking to favor a party goes too far under the Constitution.

Question presented

1. Whether plaintiffs have standing to press their partisan gerrymandering claims. 2. Whether plaintiffs' partisan gerrymandering claims are justiciable. 3. Whether North Carolina's 2016 congressional map is, in fact, an unconstitutional partisan gerrymander.

What the Court decided

Holding

Partisan gerrymandering claims present political questions beyond the reach of the federal courts. 318 F. Supp. 3d 777 and 348 F. Supp. 3d 493, vacated and remanded.

Result
Vacated

The Court's reasoning

The Court said these claims raise political questions, meaning issues federal courts cannot decide.
