Beasley, J.

Defendant was charged with assault with intent to commit murder in violation of MCL 750.83; MSA 28.278, after a woman was shot seven times with a gun.

After bindover, defendant moved for an order allowing psychiatric testimony on the issue of his capacity to form the requisite specific intent, although he filed no notice of nor did he intend to claim insanity. After careful consideration, the trial court denied defendant’s motion, holding that the 1975 amendments to the Code of Criminal Procedure codified the so-called "diminished capacity” tests and precluded any such claim except within the ambit of the statutory definition of insanity contained in the Mental Health Code.

The matter is before this court on leave granted.

Prior to enactment of the 1975 amendments, People v Lynch 1 controlled this question. In Lynch, this Court held that any evidence relevant to the issue of intent was admissible even though it fell short of supporting a finding of not guilty by reason of insanity. Specifically, the Lynch Court said:

"The majority, and we think the sounder, view, however, permits such medical proof, sometimes called proof of diminished or partial responsibility, as bearing on intent generally or at least on those special states of mind where a specific intent is required or where the state of mind by definition determines the degree of the offense as here.”

*381 The issue is, do Acts 179 and 180 of the Public Acts of 1975 modify this rule of People v Lynch so as to preclude psychiatric testimony relating to mental condition of the defendant at the time of the alleged offense except within the statutory, procedural framework for asserting the defense of insanity?

Relevant to this issue is the intention of the Legislature in enacting Acts 179 and 180 of the Public Acts of 1975. Since these acts comprise a package of bills which are quite comprehensive in scope, they are best viewed in their entirety. To that end, we set forth Acts 179 and 180 in full. 2

Giving consideration to the specifics, § 21a defines legal insanity as follows:

*390 "(1) A person is legally insane if, as a result of mental illness as defined in section 400a of Act No. 258 of the Public Acts of 1974, being section 330.1400a of the Michigan Compiled Laws, or as a result of mental retardation as defined in section 500(g) of Act No. 258 of the Public Acts of 1974, being section 330.1500 of the Michigan Compiled Laws, that person lacks substantial capacity either to appreciate the wrongfulness of his conduct' or to conform his conduct to the requirements of law.” 3

"Mental illness” is defined in the 1974 Mental Health Code as follows:

"As used in this chapter, 'mental illness’ means a substantial disorder of thought or mood which significantly impairs judgment, behavior, capacity to recognize reality, or ability to cope with the ordinary demands of life.” 4

*391 "Mentally retarded” is defined as follows:

" 'Mentally retarded’ means significantly subaverage general intellectual functioning which originates during the developmental period and is associated with impairment in adaptive behavior.” 5

The new § 21a codifies the definition of legal insanity for the first time. In the 1971 case of People v Martin, 6 the Supreme Court compared the Michigan test for criminal insanity with the American Law Institute Model Penal test, the proposed Michigan Revised Criminal Code, the Durham 7 "product” test and others. The Michigan rule as enunciated in People v Martin is

"The salient elements of the Michigan test are: 1) whether defendant knew what he was doing was right or wrong; and 2) if he did, did he have the power, the will power, to resist doing the wrongful act? The Michigan test encompasses not only a sudden overpowering, irresistible impulse but any situation or condition in which the power, 'the will power’ to resist, is insufficient to restrain commission of the wrongful act.” (Footnote omitted.)

Clearly, Michigan’s new codified definition is closest to the ALI model. The reference in the statutory definition to substantial capacity is in contrast to Michigan’s long-time Durfee 8 test which was not cast in terms of capacity. While there are those who will say this difference is mere terminology and not one of substance, the new codified definition does suggest a legislative intention to cover and include the diminished capacity *392 concept. While we are not prepared to say they are identical, certainly the categories of the mentally retarded, as defined in the statute, and of those with diminished capacity have striking similarities. It would appear that in many cases a person claiming diminished capacity would fall in the category of the mentally retarded.

Also bearing on the issue here is the new § 20a 9 which, as indicated, was part of Act 180.

Prior to the 1975 amendment, a defendant desiring to establish the defense of insanity was required to file and give notice in writing to the prosecutor of intention to claim such defense at the time of arraignment or within 10 days thereafter, but not less than four days before trial.

The 1975 amendment requires the written notice of intention to assert the defense of insanity to be given not less than 30 days before the date set for trial or such other time as the court directs. The obvious reason for gearing the new extended 30-day period to the date of trial is to afford time for the required examination by the Center for Forensic Psychiatry (hereinafter referred to as CFP) under § 20a(2).

Requiring a defendant who claims the defense of insanity to submit to examination by the CFP is, of course, an entirely new concept. The subsections contained in § 20a(2) through 20a(8) are all new.

Section 20a(3) provides that if a defendant obtains an independent (additional) psychiatric evaluation by a clinician of his choice, he must give notice to the prosecutor so that the prosecutor can also obtain an independent psychiatric evaluation if he wishes.

Section 20a(4) requires the defendant to fully cooperate with the personnel of the CFP and with *393 any independent examiners for either defense or prosecution. This section contains teeth in that if the trial judge finds failure to cooperate, he may bar the defendant from presenting testimony relating to insanity at trial.

Section 20a(5) provides that statements made by defendant to personnel of CFP or to any independent examiner are not admissible in evidence nor possessed of probative value on any issue other than mental illness or insanity at the time of the alleged offense.

Section 20a(6) requires the CFP or any other independent examiner to submit a written report to both defense counsel and the prosecutor containing 1) clinical findings, 2) facts upon which based, and 3) opinion on the issue of defendant’s insanity at the time the alleged offense was committed and whether defendant was mentally ill or mentally retarded at the time the alleged offense was committed.

Section 20a(7) requires the prosecutor to give written notice of rebuttal of defense of insanity with the names of rebuttal witnesses to defense counsel at least five days before trial.

The amended § 21 10 provides if defendant fails to file written notice of intention to claim defense of insanity in conformance with § 20a, the court shall exclude evidence offered by defendant for the purpose of establishing insanity. Prior to the amendment, exclusion of evidence because of failure to file notice of an insanity claim was within, the discretion of the trial judge; the language of the amendment makes exclusion mandatory. The provision is equally mandatory if the prosecutor fails to file the required notice of rebuttal of insanity defense.

*394 In requiring the trial judge to instruct the jury regarding the statutory definitions of legal insanity, mental illness and mentally retarded before testimony is presented on that issue in all cases where a defendant asserts the defense of insanity, § 29a(l) 11 is further indication of the Legislature’s determination to clarify for juries what the law is regarding the defense of insanity.

Of course, § 29a is entirely new. Section 29a(2) provides that where the evidence warrants, the trial judge should instruct the jury to consider separately the issue of the presence or absence of mental illness and of legal insanity. Requiring this instruction for separate consideration is an obvious effort to eliminate the necessary fuzziness that surrounds mixing the issues of whether a defendant committed an act with that of the defense of insanity.

Section 29a(2) also requires that where warranted by the evidence, the trial judge shall instruct as to the verdicts of guilty, guilty but mentally ill, not guilty by reason of insanity, and not guilty (and any lesser included offense).

Section 36 12 defines the newly created verdict of guilty but mentally ill. Where a defense of insanity is asserted and the trier of fact finds 1) defendant is guilty of an offense, 2) defendant was mentally ill at the time of commission of the offense, 3) defendant was not legally insane at the time of commission of the offense, a defendant. may be found guilty but mentally ill.

We interpret these statutes to manifest an intention to bring under one procedural blanket all defenses to criminal charges that rest upon legal insanity as defined in the statute.

*395 The codified definition of legal insanity extends to persons lacking substantial capacity either to appreciate the wrongfulness of their conduct or to conform their conduct to the requirements of law, whether it results from mental illness or mental retardation.

We find that the defense known as diminished capacity comes within this codified definition of legal insanity. We further find that psychiatric testimony on the issue of defendant’s capacity to form the specific intent comes within the codified definition of legal insanity. By thus categorizing defendant’s defense we do not preclude the admission of evidence supporting defendant’s claim that, although not legally insane, he lacks mental capacity to entertain the specific intent that is a necessary element of assault with intent to commit murder. But, we hold that defendant must give the notice required by the statute of intention to assert that defense. By so doing, defendant will submit himself to examination and evaluation by the Center for Forensic Psychiatry and by an independent psychiatrist selected by the prosecutor, if the prosecutor wishes. In short, we hold that if defendant chooses to avail himself of the defense that he here asserts, namely, that he lacks mental capacity to entertain the specific intent required as an element of the crime with which he is charged whether it be called the defense of diminished capacity or not, then full compliance must be had with §§ 20a, 29a and 36.

Consequently, we find that the package of statutes discussed in this opinion operate to modify the holding in Lynch.

The Lynch rule placed judges and juries in an impossible position. Under that decision, the psychiatrist could testify that a defendant lacked *396 mental capacity to entertain a particular criminal intent but could not testify that defendant did not know right from wrong or that defendant had an irresistible impulse to commit the criminal act or otherwise testify that defendant was insane, because such latter testimony was precluded where defendant did not claim and give notice of claim of insanity. Our interpretation of the new 1975 amendments seeks to restore credibility and clarity to the issues submitted to juries. In addition, bringing these issues under the new procedures gives the trial judge opportunity for more timely and more practical instructions to juries.

For the reasons indicated, we affirm the trial court’s denial of defendant’s petition.

Affirmed.

Sec. 21a. (1) A person is legally insane if, as a result of mental illness as defined in section 400a of Act No. 258 of the Public Acts of 1974, being section 330.1400a of the Michigan Compiled Laws, or as a result of mental retardation as defined in section 500(g) of Act No. 258 of the Public Acts of 1974, being section 330.1500 of the Michigan Compiled Laws, that person lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law.

(2) A person who is under the influence of voluntarily consumed or injected alcohol or controlled substances at the time of his alleged offense shall not thereby be deemed to have been legally insane.

768.29a Defense of insanity in criminal action tried before jury; instructions. [M.S.A. 28.1052(1)]

Sec. 36. (1) If the defendant asserts a defense of insanity in compliance with section 20a, the defendant may be found "guilty but mentally ill” if, after trial, the trier of fact finds all of the following beyond a reasonable doubt:

(a) That the defendant is guilty of an offense.

(b) That the defendant was mentally ill at the time of the commission of that offense.

(2) If the defendant asserts a defense of insanity in compliance with section 20a and the defendant waives his right to trial, by jury or by *389 judge, the trial judge, with the approval of the prosecuting attorney, may accept a plea of guilty but mentally ill in lieu of a plea of guilty or a plea of nolo contendere. The judge may not accept a plea of guilty but mentally ill until, with the defendant’s consent, he has examined the report or reports prepared pursuant to section 20a, has held a hearing on the issue of the defendant’s mental illness at which either party may present evidence, and is satisfied that the defendant was mentally ill at the time of the offense to which the plea is entered. The reports shall be made a part of the record of the case.

(3) If a defendant is found guilty but mentally ill or enters a plea to that effect which is accepted by the court, the court shall impose any sentence which could be imposed pursuant to law upon a defendant who is convicted of the same offense. If the defendant is committed to the custody of the department of corrections, he shall undergo further evaluation and be given such treatment as is psychiatrically indicated for his mental illness or retardation. Treatment may be provided by the department of corrections or by the department of mental health after his transfer pursuant to sections 1000 or 1002 of Act No. 258 of the Public Acts of 1974, being sections 330.2000 or 330.2002 of the Michigan Compiled Laws. Sections 1004 and 1006 of Act No. 258 of the Public Acts of 1974 shall apply to the discharge of such a defendant from a facility of the department of mental health to which he has been admitted and shall apply to the return of such a defendant to the department of corrections for the balance of the defendant’s sentence. When a treating facility designated by either the department of corrections or the department of mental health discharges such a defendant prior to the expiration of his sentence, that treating facility shall transmit to the parole board a report on the condition of the defendant which contains the clinical facts, the diagnosis, the course of treatment, and the prognosis for the remission of symptoms, the potential for recidivism and for the danger to himself or the public, and recommendations for future treatment. In the event that the parole board pursuant to law or administrative rules should consider him for parole, the board shall consult with the treating facility at which the defendant is being treated or from which he has been discharged and a comparable report on the condition of the defendant shall be filed with the board. If he is placed on parole by the parole board, his treatment shall, upon recommendation of the treating facility, be made a condition of parole, and failure to continue treatment except by agreement with the designated facility and parole board shall be a basis for the institution of parole violation hearings.

(4) If a defendant who is found guilty but mentally ill is placed on probation under the jurisdiction of the sentencing court pursuant to law, the trial judge, upon recommendation of the center for forensic psychiatry, shall make treatment a condition of probation. Reports as specified by the trial judge shall be filed with the probation officer and the sentencing court. Failure to continue treatment, except by agreement with the treating agency and the sentencing court, shall be a basis for the institution of probation violation hearings. The period of probation shall not be for less than 5 years and shall not be shortened without receipt and consideration of a forensic psychiatric report by *390 the sentencing court. Treatment shall be provided by an agency of the department of mental health, or with the approval of the sentencing court and at individual expense, by private agencies, private physicians, or other mental health personnel. A psychiatric report shall be filed with the probation officer and the sentencing court every 3 months during the period of probation. If a motion on a petition to discontinue probation is made by the defendant, the probation officer shall request a report as specified from the center for forensic psychiatry or any other facility certified by department of mental health for the performance of forensic psychiatric evaluation.
