Can a defendant with a history of mental illness be found not guilty of committing a crime by reason of mental health?

⁶ E.g., People v. Wetmore (1978) 22 Cal.3d 318, 321, 149 Cal.Rptr. 265, 583 P.2d 1308 (Wetmore ) (in burglary case against defendant with a "long history of psychotic illness" who "entered an apartment under a delusion that he owned that apartment and thus did not enter with the intent of committing a theft or felony," conviction reversed on ground that excluded psychiatric evidence of mental illness was admissible to negate specific intent), superseded by statute as explained in Mills , supra , 55 Cal.4th at page 671, 147 Cal.Rptr.3d 833, 286 P.3d 754.
