Background

Americans for Prosperity and its foundation challenged Arizona Proposition 211, the Voters’ Right to Know Act. The measure requires significant campaign-media spenders to identify original funding sources and imposes related recordkeeping and disclaimer duties.

The organizations alleged that tracing contributions through intermediaries chilled speech and association, swept too broadly, and compelled disclosure of donors who did not earmark money for Arizona political activity.

The Court’s Holding

A divided Ninth Circuit panel affirmed dismissal of the facial and as-applied challenges. Applying exacting scrutiny, the majority found a substantial relationship between source disclosure and Arizona’s important interest in giving voters accurate information about major campaign-media spending.

The majority characterized the burdens as modest and the thresholds, opt-out rules, and protection against serious physical harm as adequate tailoring. The as-applied allegations lacked specifics, and the compelled-association claims overlapped with the unsuccessful disclosure challenge. Judge Bumatay dissented.

Key Takeaways

  • Campaign-disclosure laws receive exacting scrutiny, which requires a substantial relation and narrow tailoring but not the least restrictive means.
  • Arizona may require tracing to original funding sources for large campaign-media expenditures.
  • Concrete facts showing threats, harassment, or other burdens are critical to an as-applied challenge.
  • A compelled-association theory does not add much when it duplicates a rejected disclosure claim.

Why It Matters

The ruling strengthens disclosure regimes aimed at identifying the true sources behind large election-media expenditures. Advocacy organizations operating across state lines should maintain contribution records and opt-out processes while documenting any concrete burdens that might support narrower as-applied relief.
