Section 220.15. Plea; plea of not responsible by reason of mental disease or defect

1. The defendant may, with both the permission of the  court  and  the
  consent  of  the  people,  enter  a plea of not responsible by reason of
  mental disease or defect to the entire indictment. The district attorney
  must state to the court either orally on the  record  or  in  a  writing
  filed  with  the court that the people consent to the entry of such plea
  and that the people are satisfied that the affirmative defense  of  lack
  of  criminal  responsibility by reason of mental disease or defect would
  be proven by the  defendant  at  a  trial  by  a  preponderance  of  the
  evidence.      The  district attorney must further state to the court in
  detail the evidence available to the people with respect to the  offense
  or  offenses  charged  in  the  indictment,  including  all  psychiatric
  evidence available or known to the people.  If necessary, the court  may
  conduct  a  hearing  before accepting such plea.   The district attorney
  must further state to the court the reasons for recommending such  plea.
  The reasons shall be stated in detail and not in conclusory terms.
    2.  Counsel for the defendant must state that in his opinion defendant
  has  the capacity to understand the proceedings and to assist in his own
  defense and that the defendant understands the consequences of a plea of
  not responsible by reason of mental disease or defect.  Counsel for  the
  defendant  must  further  state whether in his opinion defendant has any
  viable defense to the offense or  offenses  charged  in  the  indictment
  other than the affirmative defense of lack of criminal responsibility by
  reason  of  mental  disease or defect.    Counsel for the defendant must
  further state in  detail  the  psychiatric  evidence  available  to  the
  defendant with respect to such latter affirmative defense.
    3.    Before  accepting  a plea of not responsible by reason of mental
  disease or defect, the court must address the defendant  in  open  court
  and determine that he understands each of the following:
    (a)    The  nature of the charge to which the plea is offered, and the
  consequences of such plea;
    (b)  That he has the right to plead not guilty or to persist  in  that
  plea if it has already been entered;
    (c)    That  he  has the right to be tried by a jury, the right to the
  assistance of counsel, the right to confront and cross-examine witnesses
  against him, and the right not to be compelled to incriminate himself;
    (d)  That if he pleads not responsible by reason of mental disease  or
  defect  there  will be no trial with respect to the charges contained in
  the indictment, so that by offering such plea he  waives  the  right  to
  such trial;
    (e)   That if he pleads not responsible by reason of mental disease or
  defect the court will ask him questions about the  offense  or  offenses
  charged  in  the indictment and that he will thereby waive his right not
  to be compelled to incriminate himself; and
    (f)  That the acceptance of a plea of not  responsible  by  reason  of
  mental  disease  or  defect  is  the  equivalent  of  a  verdict  of not
  responsible by reason of mental disease or defect after trial.
    4.  The court shall not accept a plea of not responsible by reason  of
  mental  disease  or  defect  without  first  determining that there is a
  factual basis for such plea.   The  court  must  address  the  defendant
  personally  in  open  court  and  determine  that the plea is voluntary,
  knowingly made, and not the result of force, threats, or promises.   The
  court  must inquire whether the defendant's willingness to plead results
  from prior discussions between the district attorney and counsel for the
  defendant.  The court must be satisfied that the  defendant  understands
  the  proceedings  against  him, has sufficient capacity to assist in his
  own  defense  and  understands  the  consequences  of  a  plea  of   not

  responsible  by  reason of mental disease or defect.  The court may make
  such inquiry as it deems necessary or appropriate  for  the  purpose  of
  making the determinations required by this section.
    5.    Before  accepting  a plea of not responsible by reason of mental
  disease or defect, the court must find and state each of  the  following
  on the record in detail and not in conclusory terms:
    (a)  That it is satisfied that each element of the offense or offenses
  charged in the indictment would be established beyond a reasonable doubt
  at a trial;
    (b)    That the affirmative defense of lack of criminal responsibility
  by reason of mental disease or defect would be proven by  the  defendant
  at a trial by a preponderance of the evidence;
    (c)  That the defendant has the capacity to understand the proceedings
  against him and to assist in his own defense;
    (d)  That such plea by the defendant is knowingly and voluntarily made
  and that there is a factual basis for the plea;
    (e)    That the acceptance of such plea is required in the interest of
  the public in the effective administration of justice.
    6.  When a plea of not responsible by  reason  of  mental  disease  or
  defect  is  accepted  by  the  court  and recorded upon the minutes, the
  provisions of section 330.20 of this chapter shall govern all subsequent
  proceedings against the defendant.
