Source-derived summary

Knox v. Service Employees International Union, 567 U.S. 298 (2012), is a United States constitutional law case. The United States Supreme Court held in a 7–2 decision that Dianne Knox and other non-members of the Service Employees International Union did not receive the required notice of a $12 million assessment the union charged them to raise money for the union's political fund. In a tighter 5–4 ruling, the court further held that the long-standing precedent, the First Amendment requirement that non-union members covered by union contracts be given the chance to "opt out" of special fees was insufficient. Setting new precedent, the majority ruled that non-members shall be sent notice giving them the option to opt into special fees.

Background

Under Abood v. Detroit Board of Education (1977) states may allow unions to charge nonmember workers “fair share” fees to prevent the free rider problem of nonmembers benefiting from a union's collective bargaining gains. Nonmembers must annually opt out of paying full union membership dues after the union sends a Hudson notice of what portion of the dues is chargeable to collective bargaining costs. California is one of the states that allow for such an “agency shop”.

Arnold Schwarzenegger won a recall election against California Governor Gray Davis in November 2003.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 2012 United States Supreme Court case. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 15, 2025. The linked authority identifier is Q18151100. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012, 1977 and 2003.

Critical limits
