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.
