Today we filed our fourth amicus brief in the U.S. Supreme Court on behalf of 22 organizations and fundraisers opposing a California requirement that nonprofits surrender the names of their large donors before soliciting contributions in that state. Now, we are urging the U.S. Supreme Court to review a decision of the Ninth Circuit.This is the sixth brief we filed defending the right of nonprofits to withhold IRS Form 990 Schedules B, protecting the anonymity of their donors. In our brief, we address four issues —why such disclosure demands are unconstitutional for four reasons: freedom of association under NAACP v. Alabama ex rel. Alabama; blanket restrictions of charitable solicitation under Madigan v. Telemarketing Associates; breach of anonymity under Watchtower v. Village of Stratton and Talley v. California; and lastly, because in addition to retaliation by the public, government officials could retaliate against those donors funding nonprofits working to oppose government policies.
