2006 New Mexico Statutes - Section 31-9-3 — Criminal trials; plea and verdict of guilty but mentally ill.

31-9-3. Criminal trials; plea and verdict of guilty but mentally ill.

A.  A person who at the time of the commission of a criminal offense was not insane but was suffering from a mental illness is not relieved of criminal responsibility for his conduct and may be found guilty but mentally ill. As used in this section, "mentally ill" means a substantial disorder of thought, mood or behavior which afflicted a person at the time of the commission of the offense and which impaired that person's judgment, but not to the extent that he did not know what he was doing or understand the consequences of his act or did not know that his act was wrong or could not prevent himself from committing the act.   

B.  A plea or finding of guilty but mentally ill is not an affirmative defense but an alternative plea or finding that may be accepted or made pursuant to appropriate evidence when the affirmative defense of insanity is raised or the plea of guilty but mentally ill is made.   

C.  A plea of guilty but mentally ill shall not be accepted until the defendant has undergone examination by a clinical psychologist or psychiatrist and the court has examined the psychological or psychiatric reports, held a hearing on the issue of the defendant's mental condition and is satisfied that there is a factual basis that the defendant was mentally ill at the time of the offense to which the plea is entered.   

D.  When a defendant has asserted a defense of insanity, the court may find the defendant guilty but mentally ill if after hearing all of the evidence the court finds beyond a reasonable doubt that the defendant:   

(1) is guilty of the offense charged;   

(2) was mentally ill at the time of the commission of the offense; and   

(3) was not legally insane at the time of the commission of the offense.   

E.  When a defendant has asserted a defense of insanity, the court, where warranted by the evidence, shall provide the jury with a special verdict form of guilty but mentally ill and shall separately instruct the jury that a verdict of guilty but mentally ill may be returned instead of a verdict of guilty or not guilty, and that such a verdict requires a finding by the jury beyond a reasonable doubt that the defendant committed the offense charged and that the defendant was not legally insane at the time of the commission of the offense but that he was mentally ill at that time.
