On July 1, 2021, the Supreme Court struck down a California donor-disclosure law as facially unconstitutional in its decision in Americans for Prosperity Foundation v. Bonta.[1]  The law required nonprofits operating or soliciting contributions in California to disclose to the Attorney General of California information about all of its donors who contribute more than $5,000 each year (generally, through a requirement that nonprofits submit a copy of their Schedule Bs from their IRS Form 990s).[2]  The decision clarified the rules applicable to disclosure requirements with respect to the First Amendment, and while the decision itself addressed nonprofit disclosures, its scope could stretch significantly beyond this area.
