In 2007, the foundation filed a complaint against the Washington Education Association (WEA), accusing the union of unlawfully spending worker fees on politics. In response to that complaint, the state in turn sued the teachers union on the grounds that the WEA was unlawfully spending some workers' fees on politics. The matter was taken on appeal to the United States Supreme Court. The Supreme Court unanimously decided in "Davenport v. Washington Education Association" that states can require public-employee labor unions to get consent from workers before using their fees for political activities. The Washington State Legislature later modified the law in a way that blunted the court's decision.
