2021(See, e.g., Brake v. Beech Aircraft Corp. (1986) 184 Cal.App.3d 930, 937 [in a products liability lawsuit following a plane crash, the judge properly prohibited expert from relying on a statistical analysis comparing accident rates for the defendant’s aircraft with rates for other aircraft].) Given the confounding factors and unknowns in the poison control data and articles about energy drinks as a class, the judge could reasonably conclude that relying on them to form an opinion that Monster Energy causes cardiac arrythmias requires “a leap of logic or conjecture.” (Sargon, supra, 55 Cal.4th

People v. Valdezgreen
calctapp · 1997 · cited in 1 California opinions naming this issue, 2016–2016
1 sentence

2016The Supreme Court explicitly recognized that "in some circumstances, expert testimony regarding the specific defendants might be proper." (Vang, supra, 52 Cal.4th at p. 1048, fn. 4 , citing People v. Valdez (1997) 58 Cal.App.4th 494, 507 (Valdez).) After assuming the gang expert could not properly have testified about the 29 defendants under the facts of that case (Vang, at p. 1048), the Supreme Court explained that the propriety of the questions should be judged against the statutory requirement that the subject matter must be sufficiently beyond common experience to assist the trier of fact.

People v. Killebrew green
calctapp · 2002
2 sentences

2011In support of this argument, defendant Vang and the Court of Appeal rely primarily on Killebrew, supra, 103 Cal.App.4th 644 .

2011But the Court of Appeal found these questions were too closely based on the evidence in a manner that was only "thinly disguised." This conclusion transforms the requirement that a hypothetical question be rooted in the evidence into a prohibition —or at least into the confounding rule that the party posing the question must disguise from the jury the fact it is rooted in the evidence—and not "thinly," it appears, but thickly. *1047 In support of this argument, defendant Vang and the Court of Appeal rely primarily on Killebrew, supra, 103 Cal.App.4th 644 .
