Section 250.10 - Notice of intent to proffer psychiatric evidence; examination of defendant upon application of prosecutor1. As used in this section, the term "psychiatric evidence" means: (a) Evidence of mental disease or defect to be offered by the defendant in connection with the affirmative defense of lack of criminal responsibility by reason of mental disease or defect.(b) Evidence of mental disease or defect to be offered by the defendant in connection with the affirmative defense of extreme emotional disturbance as defined in paragraph (a) of subdivision one of section 125.25 of the penal law and paragraph (a) of subdivision two of section 125.27 of the penal law.(c) Evidence of mental disease or defect to be offered by the defendant in connection with any other defense not specified in the preceding paragraphs.2. Psychiatric evidence is not admissible upon a trial unless the defendant serves upon the people and files with the court a written notice of his intention to present psychiatric evidence. Such notice must be served and filed before trial and not more than thirty days after entry of the plea of not guilty to the indictment. In the interest of justice and for good cause shown, however, the court may permit such service and filing to be made at any later time prior to the close of the evidence.3. When a defendant, pursuant to subdivision two of this section, serves notice of intent to present psychiatric evidence, the district attorney may apply to the court, upon notice to the defendant, for an order directing that the defendant submit to an examination by a psychiatrist or licensed psychologist as defined in article one hundred fifty-three of the education law designated by the district attorney. If the application is granted, the psychiatrist or psychologist designated to conduct the examination must notify the district attorney and counsel for the defendant of the time and place of the examination. Defendant has a right to have his counsel present at such examination. The district attorney may also be present. The role of each counsel at such examination is that of an observer, and neither counsel shall be permitted to take an active role at the examination.4. After the conclusion of the examination, the psychiatrist or psychologist must promptly prepare a written report of his findings and evaluation. A copy of such report must be made available to the district attorney and to the counsel for the defendant. No transcript or recording of the examination is required, but if one is made, it shall be made available to both parties prior to the trial.5. If the court finds that the defendant has willfully refused to cooperate fully in the examination ordered pursuant to subdivision three of this section it may preclude introduction of testimony by a psychiatrist or psychologist concerning mental disease or defect of the defendant at trial. Where, however, the defendant has other proof of his affirmative defense, and the court has found that the defendant did not submit to or cooperate fully in the examination ordered by the court, this other evidence, if otherwise competent, shall be admissible. In such case, the court must instruct the jury that the defendant did not submit to or cooperate fully in the pre-trial psychiatric examination ordered by the court pursuant to subdivision three of this section and that such failure may be considered in determining the merits of the affirmative defense.N.Y.
