In 2005, the California State Employees Association (CSEA) union, a local affiliate of the SEIU, imposed a "special assessment" on every civil servants in its bargaining unit to pay for a campaign to defeat several California ballot initiatives. CSEA officials collected money from all employees to pay for union political activism, including those who were not union members. In 2007, a federal district court ruled that the CSEA was required to provide a notice to nonunion employees about the assessment, allow them to opt-out of paying into the union political fund, provide a refund of monies spent on union politics, and pay interest from the dates of the deductions to nonmembers who chose to opt out. After CSEA lawyers appealed the case, a Ninth Circuit panel reversed that decision in December 2010. On June 27, 2011, the United States Supreme Court announced it would review the Ninth Circuit's ruling.
