Rule of Law:
Penal Code section 25, subdivision (b), despite using the conjunctive "and," reinstates the traditional M'Naghten test for insanity, which uses a disjunctive standard. A defendant can establish insanity by proving they were incapable of either knowing the nature and quality of their act or distinguishing right from wrong.
Facts:
- Betty Horn had a history of manic-depressive disorder and had recently stopped taking her prescribed lithium medication.
- On September 17, 1982, Horn purchased gasoline at a Texaco station but was unable to pay for it.
- When the attendant refused her offer to leave her driver's license as collateral, Horn drove away from the station without paying.
- A gas station attendant pursued Horn on a motorcycle.
- Horn drove her car at speeds of 80 to 85 miles per hour and ran a red light.
- While still driving at approximately 60 miles per hour, Horn entered another intersection against a red light and collided with a motorcycle, killing its rider.
- Court-appointed psychiatrists testified that at the time of the incident, Horn's mental illness would have impaired her ability to distinguish right from wrong.
Procedural Posture:
- Betty Horn was charged with vehicular manslaughter in the trial court.
- Horn entered pleas of not guilty and not guilty by reason of insanity.
- After a bench trial on the issue of guilt, the trial court found Horn guilty as charged.
- A separate court trial was held on the insanity plea.
- The trial court found that Horn was incapable of distinguishing right from wrong, but had not proven she was also incapable of knowing the nature and quality of her act.
- Applying a strict, conjunctive reading of Penal Code section 25(b), the trial court found Horn legally sane and sentenced her to state prison.
- Horn (appellant) appealed the judgment to the Court of Appeal.

Issue:
Does Penal Code section 25, subdivision (b), which uses the conjunctive "and" to connect the two prongs of the insanity test, reinstate the traditional M'Naghten standard which uses the disjunctive "or," thereby allowing a defendant to establish insanity by proving incapacity under either prong?
Opinions:
Majority - Sparks, J.
Yes. Penal Code section 25, subdivision (b) reinstates the traditional, disjunctive M'Naghten test for insanity. The court reasoned that Proposition 8, which enacted the statute, was intended to abrogate the broad ALI insanity test from People v. Drew and return to the more stringent M'Naghten standard, not to create a draconian 'wild beast' test that would require a defendant to be a 'drooling idiot' to be found insane. The use of the conjunctive 'and' is interpreted as a 'careless draft' or scrivener's error, which can be read as 'or' to effectuate the voters' true intent. The court found no evidence in the ballot materials or legal history to suggest the voters intended such a radical departure from the well-established M'Naghten 'right or wrong' test. Therefore, a defendant need only prove one of the two prongs of the M'Naghten test to establish insanity.
Dissenting - Evans, Acting P. J.
No. The plain language of Penal Code section 25, subdivision (b) is unambiguous and must be enforced as written. The statute clearly uses the conjunctive 'and,' requiring a defendant to prove both prongs of the test to establish insanity. The court should not engage in judicial amendment by substituting 'or' for 'and' merely because the resulting standard is harsh. The voters were provided the text of the law and analysis stating it could increase the difficulty of proving insanity, and it must be presumed they intended the consequences of the clear language they enacted. The statute is not unconstitutional, and any change should come from the Legislature or the people, not the judiciary.
Analysis:
This decision is a significant example of purposive statutory interpretation, where a court looks beyond the plain meaning of a word to discern and implement the perceived intent of the lawmakers or electorate. By interpreting 'and' as 'or,' the court prevented a radical transformation of California's insanity defense into one of the strictest standards in common law history. The ruling solidified the return to the traditional M'Naghten 'right or wrong' test after the brief adoption of the ALI test in People v. Drew. The case highlights the judicial tension between adhering to plain statutory text and correcting apparent legislative drafting errors to avoid results deemed absurd or contrary to underlying public policy.
