In early 2023, Paul Newby, the Republican chief justice of North Carolina’s Supreme Court, gave the state and the nation a demonstration of the stunning and overlooked power of his office.

The previous year, the court — then majority Democrat — had outlawed partisan gerrymandering in the swing state. Over Newby’s vehement dissent, it had ordered independent outsiders to redraw electoral maps that the GOP-controlled legislature had crafted to conservatives’ advantage.

The traditional ways to undo such a decision would have been for the legislature to pass a new law that made gerrymandering legal or for Republicans to file a lawsuit. But that would’ve taken months or years.

Newby cleared a way to get there sooner, well before the crucial 2024 election.

In January — once two newly elected Republican justices were sworn in, giving the party a 5-2 majority — GOP lawmakers quickly filed a petition asking the Supreme Court to rehear the gerrymandering case. Such do-overs are rare. Since 1993, the court had granted only two out of 214 petitions for rehearings, both to redress narrow errors, not differences in interpreting North Carolina’s constitution. The lawyers who’d won the gerrymandering case were incredulous.
