What happened

Key facts

  • In Louisiana v. Callais, a 6-3 Supreme Court majority led by Justice Samuel Alito found Louisiana’s creation of a second Black-majority district unconstitutional.
  • The Supreme Court’s emergency docket included interim rulings that affected how campaigns and elections were conducted.
  • Democrats are favored to gain the House and Senate, while Republicans are seeking to prevent losses.

The brief

The Supreme Court ruled 6-3 that Louisiana’s creation of a second Black-majority congressional district was unconstitutional, with Justice Samuel Alito leading the majority. The Washington Examiner describes the ruling as one of the court’s decisions shaping the maps for the midterm elections.

Headlines from CNN and Mezha.net characterize the court’s influence as a rewriting of midterm rules, while The Wall Street Journal describes it as shaping the elections. The Washington Examiner places the ruling among Supreme Court decisions from the past year that it says affected the midterms.

It reports that the court’s October 2025 term ended on June 30 and included three major election-related rulings. The account also points to interim decisions on the court’s emergency docket, saying they affected both campaign activity and the conduct of elections. One of the other rulings addressed mail ballots in Mississippi.

The Supreme Court ruled 5-4 that federal law does not preempt the state law allowing officials to count a mail ballot postmarked by Election Day if it arrives up to five days later. The Washington Examiner calls that decision a setback for critics of less restrictive mail-ballot rules.

The ruling’s described scope concerns the conflict between federal law and Mississippi’s receipt window; it does not, in the account, set out a nationwide change to ballot deadlines. The election decisions are unfolding in a midterm cycle the Washington Examiner describes as a contest over control of Congress.

It says Democrats are favored to gain the House and Senate, while Republicans are working to prevent losses. The account connects the court’s election rulings to maps, campaign spending and election procedures, but does not provide further details about the interim orders or identify how particular campaigns were affected.

On redistricting, the Washington Examiner says the court is not expected to take up disputes again before possible map redrawings ahead of the 2028 elections. That leaves the Louisiana ruling as the principal redistricting decision in its account of the current midterm cycle, alongside the separate rulings on election procedures and mail ballots.

The source’s emphasis is on the court’s practical reach into election administration and campaign rules, while the other headlines frame that influence more broadly as a change to midterm rules or as election-shaping.

The reported 6-3 decision, the 5-4 mail-ballot ruling and the stated possibility of later map redrawings mark the specific judicial actions and future point identified in the coverage.

Why it matters

  • The ruling could require Louisiana to redraw its congressional map, changing which communities are grouped together and which candidates have a realistic chance of winning. Black voters who relied on the second majority-Black district may have less opportunity to elect candidates of their choice, while the decision may also narrow how the Voting Rights Act can be used to challenge future maps.

What to watch next

  • Whether the Supreme Court takes up redistricting disputes before possible map redrawings ahead of the 2028 elections.
  • How campaigns and election administration are affected by the interim rulings on the court’s emergency docket.
  • How Mississippi officials apply the state’s mail-ballot receipt window in elections.

How we got here

The dispute that reached the Supreme Court grew out of Louisiana’s post-2020-census congressional map. In June 2022, a federal court in *Robinson v. Ardoin* found that the map, which had one majority-Black district, likely violated Section 2 of the Voting Rights Act; the Supreme Court allowed the case to proceed.

Louisiana then enacted a new map in January 2024 with a second majority-Black district. A group of Louisiana voters challenged that map in *Louisiana v. Callais*, arguing that race had been used impermissibly in drawing district boundaries.
