Except as provided in Rule 841, a defendant who intends to introduce expert evidence relating to a mental disease or defect or any other mental condition of the defendant bearing (1) on the issue of guilt, or (2) in a capital case, on the issue of punishment, shall file with the clerk of courts not later than the time required for filing an omnibus pretrial motion provided in Rule 579 a notice of the intention to offer this expert evidence, and shall serve a copy of the notice and a certificate of service on the attorney for the Commonwealth.

(B)  FAILURE TO FILE NOTICE
   (1)  If the defendant fails to file and serve a notice of insanity or mental infirmity defense, or a notice of expert evidence of a mental condition as required by this rule, the court may exclude entirely any evidence offered by the defendant for the purpose of proving the defense, except testimony by the defendant, may grant a continuance to enable the Commonwealth to investigate such evidence, or may make any other order as the interests of justice require.
   (2)  If the defendant omits a witness from the notice of insanity or mental infirmity defense or a notice of expert evidence of a mental condition, the court at trial may exclude the testimony of the omitted witness, may grant a continuance to enable the Commonwealth to investigate such evidence, may grant a continuance to enable the Commonwealth to investigate the witness, or may make any other order as the interests of justice require.
(C)  RECIPROCAL NOTICE OF WITNESSES
Within 10 days after receipt of the defendant’s notice of the insanity or mental infirmity defense, or notice of expert evidence of a mental condition, or within such other time as allowed by the court upon cause shown, the attorney for the Commonwealth shall file and serve upon defendant’s attorney, or the defendant if unrepresented, written notice of the names and addresses of all witnesses the attorney for the Commonwealth intends to call to disprove or discredit the defendant’s claim of insanity or mental infirmity, or mental disease, defect, or other mental condition.
(D)  FAILURE TO SUPPLY RECIPROCAL NOTICE
   (1)  If the attorney for the Commonwealth fails to file and serve a list of its witnesses as required by this rule, the court may exclude any evidence offered by the Commonwealth for the purpose of disproving the insanity or mental infirmity defense, may grant a continuance to enable the defense to investigate such evidence, or may make such other order as the interests of justice require.
   (2)  If the attorney for the Commonwealth omits a witness from the list of its witnesses required by this rule, the court at trial may exclude the testimony of the omitted witness, may grant a continuance to enable the defense to investigate the witness, or may make such other order as the interests of justice require.
(E)  CONTINUING DUTY TO DISCLOSE
If prior to or during trial a party learns of an additional witness whose identity, if known, should have been included in the notice furnished under paragraphs (A) or (C), the party shall promptly notify the other party’s attorney, or if unrepresented, the other party, of the existence and identity of such additional witness.
(F)  FAILURE TO CALL WITNESSES
No adverse inference may be drawn against the defendant, nor may any comment be made concerning the defendant’s failure to call available witnesses with regard to the insanity or mental infirmity defense, when such witnesses have been prevented from testifying by reason of this rule, unless the defendant or the defendant’s attorney shall attempt to explain such failure to the jury.

Comment

   This rule, which is derived from paragraphs (C)(1)(b), (c)—(f), and (D) of Rule 573 (Pretrial Discovery and Inspection) and was made a separate rule in 2006, sets forth the notice procedures when a defendant intends to raise a defense of insanity or mental infirmity, or introduce evidence relating to a mental disease or defect or any other mental condition at trial.
   For the procedures related to the determination of mental retardation precluding imposition of a sentence of death, see Chapter 8 Part (B).
   The reference in paragraph (A) to Rule 579 (Time for Omnibus Pretrial Motion and Service) contemplates consideration of the exceptions to the time for filing set forth in Rule 579(A).
   See Rule 569 (Examination of Defendant by Mental Health Expert) for the procedures for the examination of the defendant by the Commonwealth’s expert when the defendant provides notice of an intention to raise a defense of insanity or mental infirmity or an intention to introduce expert evidence concerning his or her mental condition.
   Any motion under this rule must comply with the provisions of Rule 575 (Motions and Answers) and Rule 576 (Filing and Service by Parties).
   See Rule 576(b)(4) and Comment for the contents and form of the certificate of service.
