Federal Advisory Panel Votes to Protect Donor Privacy, Narrowing Scope of Amicus Disclosure Rules

Why It Matters

Preserving donor anonymity safeguards advocacy groups’ ability to influence appellate courts without chilling contributions, and signals that future transparency rules must meet a higher constitutional threshold.

Key Takeaways

• ACAR removed $100 donor disclosure provision from Rule 29.
• Vote was 5-1, citing privacy and constitutional concerns.
• Critics argued rule failed strict scrutiny under Buckley and AFP cases.
• Removal eases filing for short‑term members of advocacy groups.
• Decision may shape future Supreme Court amicus transparency debates.

Pulse Analysis

Amicus briefs have become a strategic weapon for interest groups seeking to sway appellate courts, and Rule 29 governs the minimal disclosures required of filing organizations. The proposed amendment sought to expose donors who joined a group solely to fund a brief, aiming to curb "sock‑puppet" advocacy. However, the amendment raised red flags about privacy, as the ACAR panel noted that forced disclosure could deter contributions and undermine the First Amendment’s protection of anonymous speech.

Legal scholars point to Supreme Court precedents such as Buckley v. Valeo and Americans for Prosperity Foundation v. Bonta, which apply strict scrutiny to mandatory disclosure regimes. Under that standard, the government must demonstrate a compelling interest and ensure the rule is narrowly tailored. Critics argued the new‑member provision failed both prongs, imposing a heavier burden on long‑standing organizations while offering little tangible transparency benefit. The ACAR’s reversal reflects a cautious approach to avoid a likely constitutional challenge that could invalidate the entire amendment.

The panel’s vote reverberates beyond the rulebook, influencing how advocacy groups plan their amicus strategies. With donor identities shielded, organizations can continue to mobilize resources for high‑profile cases like Trump v. Barbara without fear of public backlash. At the same time, the decision keeps the door open for future reforms that balance transparency with privacy, especially as courts grapple with an ever‑growing flood of amicus filings. Stakeholders will watch upcoming Judicial Conference discussions closely, anticipating whether a more narrowly tailored disclosure framework might emerge.
