Read Brief

Goldwater Institute

Filed · Apr 20, 2026

Read Brief

Thomas More Society

Filed · Apr 20, 2026

These briefs focus on how the SEC's enforcement process produces coerced "consent" and on the structural limits of agency power.

Cato Institute

Filed · Apr 15, 2026

Read Brief

Atlantic Legal Foundation

Filed · Apr 17, 2026

Argues the unconstitutional conditions doctrine bars the SEC from demanding First Amendment waivers as the price of settlement — regardless of any claim of "consent."

Read Brief

Hamilton Lincoln Law Institute & Manhattan Institute

Filed · Apr 20, 2026

Argues the SEC's blanket Gag Rule serves no legitimate government interest, uses the threat of agency action to accomplish what the SEC cannot through its enumerated powers, and is essentially unprecedented in both public and private litigation.

Read Brief

Liberty Justice Center

Filed · Apr 20, 2026

Read Brief

Institute for Justice

Filed · Apr 20, 2026

Argues the SEC cannot end its investigations by extracting lifetime waivers of citizens' right to criticize the government — and that the Ninth Circuit is increasingly an outlier in enforcing such waivers.

Read Brief

Competitive Enterprise Institute (CEI)

Filed · Apr 20, 2026

Argues Rule 202.5(e) inverts Congress's FOIA-based transparency architecture and operates as a prior restraint regardless of how it is characterized as a settlement condition.

Counsel of RecordOndray T. Harris, Marin Murdock
Read Brief

The Buckeye Institute

Filed · Apr 20, 2026

Argues the Gag Rule is unnecessary, exceeds the scope of the regulation as the SEC actually applies it, and creates an unfair, coercive enforcement scheme by restricting only the defendant's side of the public record.
