Can controversial nonprofits expect government protection from mandatory disclosures of their donor participants? New Jersey is the latest state to respond “No,” at least when Section 501(c)(4) social welfare organizations engage in lobbying or other politically related activity. Americans for Prosperity Foundation, a Section 501(c)(4) organization has asserted “Yes,” challenging this so-called “dark money” reporting and donor disclosure law as a First Amendment violation. AFP’s challenge follows on the heels of its valiant (but thus far defeated) effort against California’s more narrow donor disclosure law. Balancing our nation’s constitutional history regarding freedom of speech, association and expression rights, and related privacy interests against New Jersey’s onerous donor disclosure requirements, AFP should win the day with its newly filed injunction action.
