prove by a preponderance of the evidence that there was a “causal connection”
between the employee’s protected status and the adverse employment decision.’ ”

• “Requiring the plaintiff to show that discrimination was a substantial motivating
factor, rather than simply amotivating factor, more effectively ensures that
liability will not be imposed based on evidence of mere thoughts or passing
statements unrelated to the disputed employment decision. At the same
time, . . . proof that discrimination was a substantial factor in an employment
decision triggers the deterrent purpose of the FEHA and thus exposes the
employer to liability, even if other factors would have led the employer to make
the same decision at the time.” (Harris v. City of Santa Monica (2013) 56
Cal.4th 203, 232 [152 Cal.Rptr.3d 392, 294 P.3d 49], original italics.)
• “We do not suggest that discrimination must be alone sufficient to bring about an
employment decision in order to constitute a substantial motivating factor. But it
is important to recognize that discrimination can be serious, consequential, and
even by itself determinative of an employment decision without also being a
“but for” cause.” (Harris,supra, 56 Cal.4th at p. 229.)
• “Although [plaintiff] contends that a jury in an employment discrimination case
would not draw any meaningful distinction between ‘a motivating reason’ and ‘a
substantial motivating reason’ in deciding whether there was unlawful
discrimination, the Supreme Court reached a contrary conclusion in Harris
[supra]. The court specifically concluded that ‘[r]equiring the plaintiff to show
that discrimination was a substantial motivating factor, rather than simply a
motivating factor, more effectively ensures that liability will not be imposed
based on evidence of mere thoughts or passing statements unrelated to the
disputed employment decision.’ ” (Alamo v. Practice Management Information
Corp. (2013) 219 Cal.App.4th 466, 479 [161 Cal.Rptr.3d 758].)
