Hallucination As Evidence In a Murder Case
In People v. Padilla (2002) 103 Cal.App.4th 675, the genesis of CALJIC No. 8.73.1, the court held that a hallucination may be considered as evidence of provocation in determining whether a defendant committed a first or second degree murder.
Padilla was charged with the murder of his cellmate. (Id. at p. 677.) During the guilt phase, the trial court rejected Padilla's attempt to admit the testimony of two psychologists that the killing was retaliatory after Padilla hallucinated that his cellmate killed Padilla's father and brothers. (Ibid.)
One of the psychologists would have testified that Padilla hallucinated and the other would have testified about the concept of a hallucination as provocation. (Id. at p. 678.)
The appellate court held that a subjective test applies to determine "whether provocation or heat of passion can negate deliberation and premeditation so as to reduce first degree murder to second degree murder . . . ." (Ibid.)
Finding the jury could have concluded Padilla's hallucination provoked a heat of passion and reduced the murder from first degree to second degree, the court vacated the judgment of conviction on first degree murder. (Id. at pp. 678-679.)
