Today, we filed a brief in the Ninth Circuit supporting a challenge against the California Attorney General’s demands for the large donor lists (IRS Form 990 Schedule B) of charitable organizations who wish to register to solicit donations in that state. We argued that the AG’s requirement creates a condition precedent that violates the right to peacably assemble. We also explained that the new rule does not only risk public dissemination of donor information, as has already happened in California, but also the risk that politicized Attorney Generals in New York and California — Kamala Harris, Xavier Becerra, and Eric Schneiderman — would misuse the information. We also raised the distinct possibility that the AG is committing the federal crime of solicitation of taxpayer information because it is conditioning the ability to raise funds in California on the “voluntary” provision of the confidential donor lists. Finally, we argued that 9th Circuit precedent in similar cases improperly relied on election law cases, requiring that IFS’ case be heard en banc.
