- The Ninth Circuit must reconsider whether Alaska's limits fit Alaska's anti-corruption goal under the Supreme Court's earlier First Amendment campaign-finance rulings. The action leaves open whether the limits are constitutional in this case.
Summary: written with AI from the case record.

What it's about
The Supreme Court vacated the Ninth Circuit’s decision upholding those limits and sent the case back for reconsideration under the Court’s First Amendment campaign-finance precedents.
States balance First Amendment protections for political giving against efforts to prevent corruption or its appearance.
Question presented
Whether the evidence at trial was sufficient to show that Alaska’s $500 individual-to-candidate and individual-to-group contribution limits are closely drawn to further Alaska’s important interest in preventing quid pro quo corruption or its appearance.
What the Court decided
Holding
In light of all the foregoing, the petition for certiorari is granted, the judgment of the Court of Appeals is vacated, and the case is remanded for that court to revisit whether Alaska’s contribution limits are consistent with our First Amendment precedents.

- Remanded
The vote
What's next
The case returns to the Ninth Circuit, which must revisit whether Alaska's contribution limits comply with the Supreme Court's earlier First Amendment campaign-finance rulings. That review is the next step.
