People v. Washington

In People v. Sedeno (1974) 10 Cal.3d 703 (Sedeno), our Supreme Court said, "[T]he duty to give instructions. .. on particular defenses and their relevance to the charged offense arises only if it appears that a defendant is relying on such a defense, or if there is substantial evidence supportive of such a defense and the defense is not inconsistent with the defendants theory of the case." (Id. at p. 716, italics added.)
