In 25 California rulings on a demurrer or motion to strike aimed at a PAGA claim, the PAGA claim survived 16 times. The defense wins came from threshold problems: a notice to the state labor agency that missed the violations sued on, an earlier lawsuit over the same employees, or the one-year deadline. No court struck a PAGA claim as unmanageable.

The number

What happened to the PAGA claim Rulings
Survived 16 of 25
Knocked out, with leave to amend 5 of 25
Put on hold (stayed) because an earlier PAGA case covered the same employees 3 of 25
Knocked out for good (no leave to amend) 1 of 25

PAGA is California's Private Attorneys General Act. It lets an employee sue for Labor Code penalties on behalf of the state and other employees. These are 25 tentative rulings, as of October 24, 2026. That is a small set, so read the counts as examples, not a pattern.

What decides it: threshold issues

What the defense argued Rulings Survived What happened when the defense won
The notice to the state labor agency (LWDA) was missing or too narrow 10 7 Knocked out with leave to amend, 3
Not an aggrieved employee, not the employer, or too few facts 5 4 Knocked out with leave to amend, 1
An earlier-filed PAGA case covers the same employees 4 1 Stayed, 3
The one-year limit had run 2 1 Knocked out without leave, 1
Same case, two rounds: standing, then tolling 2 1 Knocked out with leave to amend, 1
Motion to strike PAGA allegations 2 2 None

Before suing, a PAGA plaintiff must give notice to the Labor and Workforce Development Agency (LWDA) naming the Labor Code sections at issue. When the notice missed the sections sued on, the claim lost, but with leave to amend. One court wrote: "Plaintiff’s November 4, 2024 PAGA notice to the LWDA only referenced Labor Code sections 204 and 226, subdivision (a)." (Santa Clara, 24CV450382, 2026-07-28.)

When the notice tracked the complaint, the claim survived: "Furthermore, the PAGA Notices identify each of the causes of action and labor code violations Plaintiff asserted in the FAC." (Los Angeles, 24STCV10572, 2026-08-04.)

What the average hides: an earlier case means a stay, not a dismissal

When an earlier-filed PAGA case covered the same employer and employees, the defense won 3 of 4 times. Each of those 3 was a stay, not a dismissal. One court wrote: "Plaintiff's claims against Defendant are stayed in their entirety pending resolution of" the earlier case. (Los Angeles, 25STCV33618, 2026-05-29.)

The one loss turned on the two cases covering time periods that did not overlap: "the representative actions are not actually the same." (Los Angeles, 25PSCV04678, 2026-06-16.)

No ruling struck a PAGA claim as unmanageable, and one rejected that argument at the pleading stage. The California Supreme Court has said: "We now conclude that trial courts lack inherent authority to strike PAGA claims on manageability grounds." (Estrada v. Royalty Carpet Mills, Inc. (2024) 15 Cal.5th 582.)

What to do

If you represent the employee If you represent the employer
Name every Labor Code section you sue on in the LWDA notice, and allege that you complied with the notice rules. Each of the 3 notice losses was missing one of those pieces: a section, notice to that defendant, or the compliance allegation. All 3 came with leave to amend. Compare the LWDA notice with the complaint section by section. A gap won 3 times here, tied with earlier-case stays, but each time the plaintiff got leave to amend.
Search for earlier PAGA cases against the same employer before you file. If one exists, expect a stay. If an earlier PAGA case covers the same employees, ask for a stay. It worked in 3 of 4 rulings, and the one loss was a case covering a different time period.
Calendar the one-year deadline from the last violation you rely on. Don't build the demurrer on manageability. Under Estrada, courts can't strike a PAGA claim on that ground.

Method: 25 California superior court tentative rulings, in 24 cases, on a demurrer or motion to strike aimed at a PAGA claim, as of October 24, 2026. Each ruling was coded for outcome and for the defense argument the court decided, assigned by hand from the court's stated reason. One case appears twice on purpose: a demurrer sustained with leave, then the amended complaint survived. A small set: counts and examples only, not rates. These are tentative rulings, not precedent, and these counts are not odds of winning. Nothing here is legal advice.
