ACAR Rejects Donor Disclosure Rule for Amicus Briefs in 5-1 Vote

Why It Matters

The ACAR decision preserves donor anonymity for many amicus participants, potentially expanding the pool of contributors who might otherwise stay silent due to privacy fears. This outcome could alter the dynamics of high‑profile appellate litigation, where amicus briefs often sway judicial reasoning. At the same time, the vote highlights the tension between transparency advocates and privacy proponents, a debate that will shape future rule‑making and could affect public confidence in the judicial process. For advocacy groups, the ruling removes a procedural hurdle that could have increased compliance costs and deterred grassroots funding. For courts, it maintains the status quo, allowing judges to continue evaluating amicus arguments without the added layer of donor scrutiny, but it also leaves open the question of how to ensure that undisclosed funding does not undermine the integrity of appellate advocacy.

Key Takeaways

• ACAR voted 5-1 to reject the donor‑disclosure amendment for amicus briefs.
• The proposed rule targeted donors contributing over $100 who were members for less than a year.
• Senator Sheldon Whitehouse and Congressman Hank Johnson originally pushed the disclosure requirement.
• The decision cites strict‑scrutiny concerns from *Buckley v. Valeo* and *Americans for Prosperity Foundation v. Bonta*.
• The ruling keeps Federal Rule of Appellate Procedure 29 unchanged, preserving current privacy standards.

Pulse Analysis

The ACAR panel’s narrow vote reflects a broader judicial reluctance to impose disclosure regimes that could be deemed unconstitutional under strict scrutiny. Historically, the Supreme Court has guarded donor anonymity to protect First Amendment rights, a principle reaffirmed in recent campaign‑finance cases. By rejecting the $100‑plus, less‑than‑one‑year rule, ACAR signals that any future transparency push must be narrowly tailored and backed by robust empirical evidence showing a compelling governmental interest.

From a market perspective, the decision may embolden smaller advocacy organizations and law firms that rely on modest donor contributions to file amicus briefs. Without the threat of mandatory disclosure, these entities can allocate resources more efficiently, potentially increasing the volume and diversity of amicus participation in appellate courts. Conversely, larger corporate interests, such as the US Chamber of Commerce, may view the outcome as a setback, prompting them to lobby for alternative mechanisms—perhaps tighter filing deadlines or stricter conflict‑of‑interest checks—to achieve a comparable level of transparency.

Looking ahead, the Judicial Conference is likely to revisit the issue, perhaps proposing a more limited disclosure framework that targets only high‑value contributions or cases with direct governmental interests. Stakeholders should prepare for a possible incremental approach, balancing constitutional constraints with the growing demand for openness in a legal environment where amicus briefs are increasingly pivotal to shaping federal appellate jurisprudence.
