—Notice by Defendant of Intention

To Use Expert Testimony regarding Mental State; Filing Reports of Exam If a defendant intends to introduce expert testi- mony relating to the affirmative defenses of mental disease or defect, or of extreme emotional distur- bance or another condition bearing upon the issue of whether he or she had the mental state required for the offense charged, the defendant shall, not later than forty-five days after the first pretrial conference in the court where the case will be tried or at such later time as the judicial authority may direct, notify the prosecuting authority in writing of such intention and file a copy of such notice with the clerk. The defendant shall also furnish the prosecuting authority with copies of reports of physical or mental examina- tions of the defendant prepared by an expert whom the defendant intends to call as a witness in connec- tion with the offense charged, within five days after receipt thereof. The judicial authority may for cause shown allow late filing of the notice or grant additional time to the parties to prepare for trial or make such other order as may be appropriate.
