Brief Summary
Criminal law; whether a trial court may preclude psychiatric testimony supporting an insanity defense and mental-state defense when the expert diagnosed the defendant after the crime.
The trial court found defendant competent to stand trial under CPL 730.10(1) [standard for whether a defendant is an incapacitated person, i.e., able to understand the proceedings and assist in the defense], convicted him after a jury trial of attempted aggravated murder, attempted murder in the second degree, aggravated assault upon a police officer or a peace officer, and assault in the first degree, and precluded defendant's psychiatrist from testifying in support of the defense noticed under CPL 250.10 [notice of intent to present psychiatric evidence].
The Appellate Division reversed the judgment of conviction and granted a new trial.
The court held that the preclusion of the psychiatrist's testimony was an abuse of discretion and violated defendant's constitutional right to present a defense. The post-crime bipolar diagnosis was relevant to defendant's affirmative defense under Penal Law § 40.15 [lack of criminal responsibility by reason of mental disease or defect] and to his mental-state arguments, and excluding it was not harmless.
Background
Police responded after defendant's grandmother called 911 seeking to have him removed from the home and taken to a hospital because of abnormal behavior and mental health concerns. After an officer coaxed defendant out from under a bed, defendant suddenly attacked him, repeatedly punching and stabbing him with a knife, causing severe injuries including permanent loss of vision. Defendant gave timely notice under CPL 250.10 of his intent to offer psychiatric evidence in support of an insanity defense under Penal Law § 40.15. His proposed psychiatrist had treated him about 1 1/2 years after the incident during a competency-restoration admission and diagnosed him with bipolar disorder, type 1, most recent episode manic with psychotic features, based on both post-crime observations and review of earlier medical records showing similar behavior before the attack.
Lower Court Decision
Supreme Court, Monroe County, ruled after a competency hearing that defendant was not an incapacitated person and was fit to stand trial. Before trial, it granted the People's motion in limine to preclude the psychiatrist's testimony, reasoning that the expert could not say what defendant's diagnosis was on the date of the crimes and that the testimony would be irrelevant and invite jury speculation. Defendant was then convicted by a jury of all charged offenses.
Appellate Division Reversal
The Appellate Division agreed with the trial court's competency determination and rejected defendant's claims of judicial bias at the competency hearing. But it held that the court erred in excluding the psychiatrist. The psychiatrist's diagnosis and explanation of bipolar disorder, together with his reliance on pre-crime medical records and similar earlier behavior, had a tendency to make it more probable that defendant suffered from a mental disease or defect at the time of the crimes. The expert did not need to offer the ultimate legal conclusion on insanity for the testimony to be relevant. The appellate court further held that the jury would not have been left to speculate improperly because the evidence provided a basis from which it could infer defendant's mental condition during the incident. Since the ruling effectively prevented defendant from presenting his affirmative defense and seriously undermined his ability to contest mens rea, the error was not harmless, requiring reversal and a new trial.
Legal Significance
This decision reinforces that a trial court's evidentiary discretion is limited by a criminal defendant's constitutional right to present a complete defense. In New York, psychiatric testimony may be relevant to an insanity defense even if the expert examined the defendant after the offense and cannot state with certainty the exact diagnosis on the date of the crime, so long as the opinion is grounded in observations and medical history that bear on the defendant's mental disease or defect.
A court may not mechanically exclude psychiatric evidence simply because the expert's diagnosis post-dates the crime. If the testimony could help the jury assess whether the defendant suffered from a mental disease or defect, exclusion may violate due process and require a new trial.
