ORDER RE: STANDARD OF CAUSATION FOR RETALIATION CLAIMS
DEAN D. PREGERSON, District Judge.The parties disagree on the appropriate standard of causation for Plaintiffs state law retaliation and wrongful termination in violation of public policy claims. This case involves evidence that Defendant may have had a “mixed motive” for terminating Plaintiff. This means that Defendant may have been motivated both by legitimate reasons and by improper retaliatory reasons.
Defendant argues that a “but for” standard applies to Plaintiffs claims, citing to the California Supreme Court’s decision in General Dynamics Corp. v. Superior Court, 7 Cal.4th 1164, 32 Cal.Rptr.2d 1, 876 P.2d 487 (1994).
Plaintiff argues that a “motivating reason” standard applies, as set forth in *1244Grant-Burton v. Covenant Care, Inc., 99 Cal.App.4th 1361, 122 Cal.Rptr.2d 204 (2002). This standard is essentially-adopted by Judicial Council of California Civil Jury Instruction (“CACI”) No. 2430, for “Wrongful Diseharge/Demotion in Violation of Public Policy.”
Here, Plaintiffs proposed instruction, in line with Grant-Burton and CACI No. 2430, is as follows:
RETALIATION IN VIOLATION OF PUBLIC POLICY — TERMINATION
Plaintiff Michael Mario claims that UPS retaliated against him in violation of the California Labor Code by terminating his employment. Mr. Mario has the burden of proving each of the following elements by a preponderance of the evidence:
1. That Mr. Mario engaged in protected activity;
2. UPS subjected Mr. Mario to an adverse employment action by terminating his employment; and
3. UPS terminated Mr. Mario’s employment because he engaged in protected activity — that is, that the protected activity was a motivating or substantial factor in UPS’s decision to terminate his employment.
If you find that Mr. Mario has failed to prove any of these elements, your verdict must be for UPS.
If you find that Mr. Mario has proved all three of these elements, then UPS must prove by a preponderance of the evidence that it would have made the same decision to terminate Mr. Mario even if his protected activity had not been a motivating or substantial factor in the decision. If UPS does not meet this burden, then your verdict must be for Mr. Mario.1
Having reviewed the parties’ supplemental briefs and the relevant law, the court concludes that the “motivating reason” standard is the correct one.
It is true, as Defendant argues, that General Dynamics references a “but for” standard. See 7 Cal.4th at 1191, 32 Cal.Rptr.2d 1, 876 P.2d 487 (“The plaintiff, of course, bears the burden of establishing the unequivocal requirements of the ethical norm at issue and that the employer’s conduct was motivated by impermissible considerations under a ‘but for’ standard of causation.”). In that case, however, the California Supreme Court “granted review to consider an attorney’s status as ‘in house’ counsel as it affects the right to pursue claims for damages following an allegedly wrongful termination of employment.” Id. at 1169, 32 Cal.Rptr.2d 1, 876 P.2d 487. The Court then devoted the decision to resolving aspects of this issue. Accordingly, it is in dicta, on the penultimate page, and as part of a list of “a handful of subsidiary rules [that] will effectively raise the ante on the in-house attorney contemplating a tort action,” that the Court remarked on the standard of causation. Id. at 1191, 32 Cal.Rptr.2d 1, 876 P.2d 487.
It has been eighteen years since the Supreme Court’s decision, but neither this court nor Defendant were able to locate a published case citing General Dynamics on this issue. (See Def.’s 2nd Supp. Bench Br. Re: Applicable Standard of Causation at 1 (“UPS has located five unpublished and no published) cases that have cited General Dynamics in discussing the standard of causation for public policy tort claims.”). In sum, General Dynamics did *1245not resolve the standard of causation for claims of retaliation in violation of public policy, at least where there is evidence of a mixed motive.
In contrast, there are sound reasons to find that California courts apply a “motivating reason” standard to mixed motive cases. In Grant-Burton, in a published decision, a California appellate court addressed such a claim for wrongful termination in violation of public policy, where the record reflected that the employer may also have had legitimate reasons to discharge the plaintiff. See 99 Cal.App.4th at 1379, 122 Cal.Rptr.2d 204. As the court explained:
In some cases, the evidence will establish that the employer had “mixed motives” for its employment decision. In a mixed motive case, both legitimate and illegitimate factors contribute to the employment decision. Once the employee establishes that an illegitimate factor played a motivating or substantial role in an employment decision, the burden falls to the employer to prove by a preponderance of the evidence that it would have made the same decision even if it had not taken the illegitimate factor into account.
Id. (internal quotation marks, citations, and alterations omitted) (emphasis added). Grant-Burton set forth this “motivating reason” standard eight years after the General Dynamics decision, and Grant-Burton’s analysis has not been disturbed during the decade since.
As noted above, California’s official model jury instruction for retaliation in violation of public policy has also adopted the Grant-Burton standard. See CACI No. 2430 (“To establish this claim, [plaintiff] must prove ... [t]hat [plaintiffs protected activity] was a motivating reason for [plaintiffs discharge or demotion].” (emphasis added)). The CACI instructions “are approved by the Judicial Council as the state’s official jury instructions under the California Rules of Court (see now CaLRules of Court, Rule 2.1050(a)).” CACI at xvii (Preface).
The Grant-Burton rule best furthers the fundamental policy considerations that are the basis of California’s anti-retaliation law. It is worth remembering that our governing bodies have passed many laws that are designed to prohibit odious conduct, such as laws against discrimination based on race, religion, and gender. Our governing bodies have also passed labor laws designed to protect important rights of workers, such as rights to health and safety standards, overtime pay, and meal and rest periods.
Retaliation against persons who seek the protection of these important laws, strikes at the heart of those laws; it makes them if not impotent, certainly diminished. Therefore, it is fitting that a jury be asked if retaliation motivated a defendant’s actions. If so, a jury would have established that due respect for our laws was not afforded by the defendant. Given the significance of such a finding, it is also fitting that the burden shift to that defendant to “prove by a preponderance of the evidence that it would have made the same decision even if it had not taken the illegitimate factor into account.” Grant-Burton, 99 Cal.App.4th at 1379, 122 Cal.Rptr.2d 204.
For all of these reasons, the court concludes that California applies a “motivating reason” standard with burden shifting to claims for retaliation or wrongful termination in violation of public policy. The court therefore approves the jury instruction set forth above, in accord with Grant-Burton and CACI No. 2430.2
IT IS SO ORDERED.
. Plaintiff has also provided a materially identical proposed jury instruction for his claims that Defendant retaliated against him in violation of public policy by failing to promote him.
. The parties agree that, because the court has decided on this standard, the court should also give the "Mixed Motive Defense" instruction, as provided by California Civil Jury Instrucüon (BAJI) No. 12.26. The parties have incorporated this standard into a single jury instruction, as set forth above,
