Knox v. Service Employees International Union, Local 1000
The Court ruled that a California public-sector union violated nonmembers' First Amendment rights when it imposed a special "political fight-back" fee to fight ballot measures without sending a new notice or letting objectors avoid paying for it.
Going further than prior cases required, the Court held that whenever a public-sector union imposes a special assessment or mid-year dues increase, it must get nonmembers' affirmative opt-in consent rather than just letting them opt out — tightening the rules governing compulsory union fees nationwide.
“Therefore, when a public-sector union imposes a special assessment or dues increase, the union must provide a fresh Hudson notice and may not exact any funds from nonmembers without their affirmative consent.”
The Court's core new rule requiring affirmative consent for special union assessments.
How it got here: A federal district court ordered a refund and new notice for the union's fee increase; the Ninth Circuit reversed; the Supreme Court agreed to review.
The Case in Depth
What happened
California lets public employees create "agency shop" arrangements where a union represents everyone in a bargaining unit, including nonmembers who must still pay fees for bargaining-related costs. In 2005, the SEIU sent nonunion employees a special mid-year assessment notice raising fees to fund a "Political Fight-Back Fund" aimed at defeating anti-union ballot initiatives and electing favored candidates, without giving affected employees a new chance to object or opt out.
The question before the Court
Could a public-employee union charge nonmembers for a special political fundraising assessment without giving them fresh notice and a real choice to opt out—or even opt in?
Why it matters
Public employees who don't join their workplace union gained stronger protection against being forced to bankroll union political campaigns, even temporarily. Unions representing government workers now face a higher bar — affirmative consent, not passive non-objection — before collecting special fees for electoral or ideological activity, changing how they fund political efforts.
What changes now
The case was sent back to the lower courts for further proceedings consistent with the Court's ruling, including addressing the adequacy of the refund process for the class of nonunion employees. The decision immediately requires unions nationwide to obtain affirmative consent before charging nonmembers for special assessments or dues increases, a stricter standard than the opt-out system previously used for regular annual dues.
What this does not decide
The majority said its new opt-in requirement applies specifically to special assessments and mid-year dues increases, not necessarily to a union's regular annual dues notices. However, the concurrence and dissent both warned the reasoning could logically extend further, to ordinary yearly fees, even though the Court did not decide that question here.
Concurrences and dissents
Concurrence — Justice Sotomayor
Justice Sotomayor agreed the union violated the First Amendment by not offering nonmembers a chance to opt out of the political special assessment, but would have stopped there. She objected that the majority reached beyond the questions presented and briefed by the parties to impose a broader opt-in requirement, calling this a departure from judicial restraint and from the Court's own rules limiting review to presented questions.
Dissent — Justice Breyer
Justice Breyer argued the union's basic administrative system, which calculates nonmember fees using the prior year's audited expenses, was constitutionally sound under Hudson and that the special assessment fit within that same framework. He noted objecting nonmembers actually ended up paying less than their fair chargeable share once 2005 figures were audited, so no constitutional harm occurred. He also joined Sotomayor in objecting to the majority's unrequested opt-in mandate.
How the Court got there
The legal reasoning, step by step
- The Court applied exacting First Amendment scrutiny to compelled subsidies of private speech, the standard requiring that any mandatory financial support for someone else's speech be tied to a genuine mandated association and be no broader than necessary to serve the purpose justifying that association.
- The Court explained that requiring nonmembers to affirmatively opt out of paying for a union's political spending — rather than opt in — already stretches First Amendment tolerance, since it assumes consent unless the employee acts to withhold it.
- Applying Hudson's requirement that fee-collection procedures be carefully tailored to minimize the burden on free speech rights, the Court found the union's mid-year assessment notice failed this standard because nonmembers had no fair opportunity to evaluate a fee whose political purpose was unknown when the annual notice was sent.
- The Court rejected the argument that a later refund would cure the problem, reasoning that the First Amendment forbids even a temporary, interest-free 'loan' of unwilling nonmembers' money for political purposes, regardless of eventual repayment.
- Because the assessment was billed entirely for electoral purposes, the Court concluded that the risk of misallocation between chargeable and nonchargeable spending should fall on the union rather than the nonmembers, since only the nonmembers had a constitutional right at stake.
- The Court held that going forward, any special assessment or dues increase must be preceded by a fresh notice, and unions may not collect any money from nonmembers for such assessments without their affirmative, opt-in consent.
