The California Teachers Association has sued the state over $3.9 billion in school funding it says was improperly withheld from the 2025–26 Proposition 98 guarantee, opening a new legal fight over how Sacramento manages revenue uncertainty without cutting the constitutional minimum for K–12 schools and community colleges.

The union’s September 15 announcement says its petition seeks a court order restoring the money, a declaration that an earlier $1.9 billion withholding for 2024–25 was unconstitutional, and limits on using the same budget mechanism again. CTA represents about 310,000 educators and says the current holdback equals roughly $640 per student statewide.

Proposition 98, adopted by voters in 1988, establishes formulas for a minimum annual education guarantee. The present dispute is not simply whether schools eventually receive money. It is whether the state may recognize the amount as owed while postponing payment outside the ordinary guarantee, effectively leaving districts to absorb the near-term gap.

The California School Boards Association supports the challenge and said it plans a separate filing on September 22. CSBA argues that an indefinite holdback complicates staffing, class-size decisions and multiyear budgeting because districts must adopt balanced plans before uncertain state revenue is resolved. The association also has pending litigation concerning the earlier fiscal-year treatment.

The Newsom administration disputes the premise that it has failed to fund the guarantee. In a Department of Finance response, the state said the 2024–25 Proposition 98 obligation was fully funded and that the budget complied with constitutional requirements. The San Francisco Chronicle reported that the lawsuit names Finance Director Joe Stephenshaw and that the administration expects to meet its school-funding commitments.

The case will require a court to distinguish a lawful timing adjustment from an unconstitutional reduction or deferral. That question matters beyond this budget cycle: if the state prevails, future governors and lawmakers may retain more flexibility when tax receipts fluctuate; if CTA prevails, California could face a tighter rule requiring protected education dollars to be paid on the constitutional schedule.

For families and school employees, there is no immediate statewide change to calendars, enrollment or classroom operations. District-level consequences will depend on local reserves and budgets. CTA says nearly 1,000 educator layoffs already reflect fiscal pressure, but the lawsuit itself does not automatically reverse personnel decisions.

The next practical milestones are the state’s formal response, assignment of a hearing schedule and CSBA’s expected filing. Until a judge rules or lawmakers revise the budget, the $3.9 billion remains the central disputed amount rather than money districts can treat as immediately available.

Budget timing is especially consequential for smaller districts with limited reserves. Even when the state ultimately pays an obligation, a delay can force local boards to freeze hiring, postpone purchases or plan conservatively. Those operational effects help explain why education groups are asking for a judicial rule now instead of waiting for a later budget reconciliation.
