dissenting.
I respectfully dissent. In my opinion, counsel for Appellant by not citing State v. Shipman, 568 S.W.2d 947 (Mo.App.1978), rendered ineffective assistance of counsel entitling the Appellant to relief under Rule 29.15. It was Appellant’s counsel’s decision to rely upon the defense of mental disease or defect. This reliance was well founded, considering the absolutely bizarre and irrational conduct of the defendant and the unexplained absence of any motive for the Appellant’s assault upon his friend. That decision was confirmed by the examination and opinion of psychologist Dr. Tim McCarty. The capstone of that strategy was to be the testimony of Dr. McCarty.
In responding to the charge of assault in the first degree, § 565.050, RSMo Supp. 1995, the Appellant entered a plea of not guilty by reason of mental disease or defect. At the trial at which Appellant was convicted, the court sustained the State’s motion in limine to prohibit the introduction of any evidence of voluntary intoxication or voluntary drug use upon the Appellant’s state of mind.
Nonetheless, Appellant made an offer of proof of the testimony of Dr. Tim McCarty, a psychologist, whose qualifications to testify concerning substance abuse and mental diseases and defects were established in that offer. Dr. McCarty treated and examined the Appellant. It was the doctor’s opinion that, disregarding any history of Appellant’s use of alcohol or drugs, based upon the Appellant’s behavior preceding, at the time of, and after the attack, the Appellant was psychotic. The doctor explained that psychotic disorders include schizophrenia, schizophrenia paranoia and catatonic. That such disorders can result from genetic or hereditary components, a chemical disorder in the brain and trau-mátie events in life and substance abuse. He distinguished between a substance induced psychotic disorder and a substance related disorder or an intoxicated state. In essence it was his opinion at the time of thé assault Appellant was suffering from a substance-induced psychotic disorder as opposed to substance intoxication at the time of the assault. In other words, the Appellant was suffering from an underlying mental disease or defect which existed independently from any degree of intoxication resulting from the recent ingestion of alcohol or drugs. That as a result of the substance-induced psychotic disorder that at the time of the assault Mouse was not capable of knowing and appreciating *153the nature, quality or wrongfulness of his conduct. The offer of proof was refused upon the basis of the motion in limine.
Section 562.086, RSMo provides:
1. A person is not responsible for criminal conduct if at the time such conduct as a result of mental disease or defect he was incapable of knowing and appreciating the nature, quality or wrongfulness of his conduct.
2. The procedures for the defense of lack of responsibility because of mental disease or defect are governed by the provisions of Chapter 552.
Mental disease or defect is defined by § 552.010, quoted in the majority opinion. The critical provision is “(t)he terms mental disease or defect do not include alcoholism without psychosis or drug abuse without psychosis.... ” That section restates the long-standing law in Missouri that voluntary intoxication, without psychosis, does not relieve a defendant from responsibility.
The revision of the Criminal Code in 1979 included the version of § 562.076 first quoted in the majority opinion. This version provided for the defense of voluntary intoxication to negative the culpable mental state of “purposely” or “knowingly.” See § 562.016. The result was that voluntary intoxication was a basis for diminished capacity. This result, which changed the long-established law in Missouri, was of short duration. In 1983, the version of § 562.076, next quoted in the majority opinion, was adopted. The later version not only reinstated the principle of responsibility, but mandated that when there is evidence a defendant has been using alcohol or drugs the jury shall be instructed that voluntary intoxication cannot negate a mental state. The history of the relevant statute is traced in State v. Erwin, 848 S.W.2d 476 (Mo.banc 1993).
Nonetheless, the definition of mental disease or defect remained unaltered. Section 552.010 yet provides “(the) terms mental disease or defect do not include alcoholism without psychosis or drug abuse without psychosis.... ” That definition was construed and the fundamental principle of the relationship between psychosis and intoxication has been succinctly stated.
‘Psychosis’ and ‘insanity’ are synonymous ... and ‘insanity’ is to be equated to the incapacity of distinguishing right from wrong. The right-wrong insanity text attributed to M’Naghten case ... has been applied to defenses of drug addiction in like manner as applied to insanity resulting from other causes. While it must be recognized that a drug addiction without psychosis is not a defense ..., a mental disease or defect which results in insanity or the inability to distinguish right from wrong is still a defense although the disease or defect had its origin and was nurtured into legal irresponsibility through drug abuse or addiction. Stated differently: If a psychosis exists by reason of defendant’s inability to tell right from wrong or inability to know or appreciate the nature, quality or wrongfulness of his conduct or incapacity to conform his conduct to the requirements of law (§ 552.030), how or why the mental disease or defect arose should be of no moment, (citations omitted)
Shipman, 568 S.W.2d at 950.
This fundamental principle was the foundation for the admission of the evidence of the examination by Dr. Tim McCarty and his opinion that Appellant at the time of the assault, because of his psychosis, was not capable of knowing and appreciating the nature, quality, or wrongfulness of his conduct. This testimony was essential to the defense offered by counsel for Appellant. Yet, counsel did not cite to the trial *154court the most prominent and clear statement of that fundamental principle, Ship-man, supra.
This statement in Shipman, supra, was and is good law. It is supported by the authorities cited in that opinion.1 It is the foundation of the instruction on mental disease or defect. See MAI-CR3d 306.02A and MAI-CR3d 333.00. See also State v. Smith, 649 S.W.2d 417, 431 (Mo.banc 1983);
The fundamental principle stated in Shipman was recognized with approval in State v. Ingram, 607 S.W.2d 438, 441 (Mo.1980).
There was no evidence presented which indicates, or from which an inference could be drawn, that appellant was psychotic, or that he could have been suffering from a mental disease or defect excluding responsibility within the meaning of § 662.010. Therefore, the court properly denied the untimely attempt to interpose the defense. See State v. Sears, supra.2
The fundamental principle of Shipman has been restated by the Supreme Court. “Merely being in a state of drug or alcohol intoxication does not provide a recognizable defense under the law unless it has resulted in psychosis. State v. Ingram, 607 S.W.2d 438, 441 (Mo.1980); State v. Shipman, 568 S.W.2d at 950.” State v. Preston, 673 S.W.2d 1, 8 (Mo.banc 1984) (emphasis added).
This fundamental principle of Shipman was subsequently restated: “Certainly, merely being intoxicated as a result of alcohol or drug use does not provide a defense under the law unless it has resulted in psychosis.” State v. Williams, 812 S.W.2d 518, 520 (Mo.App.1991).
The fundamental principle stated in Shipman is the basis of the Supreme Court’s disapproval of an instruction patterned after MAI-CR3d 310.50, which read, “You are instructed that an intoxicated condition from alcohol will not relieve a person of responsibility for his conduct.” This essentially is the holding of State v. Mouse, 989 S.W.2d 185 (Mo.App.1999). That instruction was condemned in the following language:
We turn now to the instruction, MAI-CR3d 310.50. The instruction is not a misstatement of law. However, the same may be said of the instruction in Sandstrom, supra.3 The critical question is whether a reasonable likelihood exists that the jury understands the instruction to relieve the state of its burden of proof as to a statutory element. The instruction here creates a reasonable likelihood that the jury would be*155lieve that if defendant was intoxicated, he was criminally responsible regardless of his state of mind. That reading has the effect of excusing the state from proving the defendant’s mental condition beyond a reasonable doubt and violates due process under Sandstrom.
Erwin, 848 S.W.2d at 483 (emphasis added).
On the direct appeal of Appellant’s conviction, his counsel, by point I of his brief, asserted that the Appellant “should have been permitted to present expert testimony to show he suffered from a mental disease or defect that prevented him from knowing and appreciating the nature, quality and wrongfulness of his conduct at the time of the offense.” Counsel did not cite Shipman, supra, to this court. In affirming Appellant’s conviction, this court noted his argument that “the italicized part of the statute implicitly states that alcoholism with psychosis or drug abuse with psychosis is a mental disease or defect.” The court concluded “(t)hat argument, however, was rejected in State v. McGreevey, 832 S.W.2d 929 (Mo.App.1992).” Mouse, 989 S.W.2d 185, 189 (Mo.App.1999). The issue of what may be a mental disease or defect was not decided by McGreevey. In that case, the rejection of the proffered testimony of a psychologist was affirmed upon the following basis:
It is true that Missouri at one time allowed a defendant to use voluntary intoxication/drug use as a defense if it negatived the mental state necessary for the crime (§ 562.076.1(1), RSMo 1978; effective January 1, 1979, repealed October 1,1984).
However, there is no current support for this position. Section 562.076.1, RSMo 1986, effective before the date of the incident, states:
A person who is in an intoxicated or drugged condition whether from alcohol, drugs or other substance, is criminally responsible for conduct unless such condition is involuntarily produced and deprived him of the capaci-
ty to know or appreciate the nature, quality or wrongfulness of his conduct. As settled by the cases of State v. Woltering, 810 S.W.2d 584, 587-588 (Mo.App.1991), and State v. Elam, 779 S.W.2d 716, 717 (Mo.App.1989), § 562.076.1 brings Missouri back to the common law rule that voluntary intoxication is no defense to a criminal charge. There is no showing in the record that Dr. Mandracchia could testify that McGreevey’s drugged and demented condition deprived McGreevey of the appreciation of the nature of his conduct

McGreevey, 832 S.W.2d at 931.
McGreevey and the cases that opinion relies upon are inapposite to the argument of movant and the fundamental principle stated in Shipman. That is emphasized by the following excerpts from those cases:
After closing arguments the court stated that it would not have instructed a jury on the defense of mental disease or defect had the case been tried to a jury. The court observed, ‘[Tjhere was no testimony that the defendant was in a psychotic state prior to the ingestion of the drug on the day in question’ and concluded,
I have come to the conclusion that the psychosis had to exist prior to the ingestion in order to qualify under the law that says if you’ve got alcohol plus a psychosis you can submit it.
Elam, 779 S.W.2d at 717.
As discussed in Point I, no medical evidence was introduced which indicated defendant suffered from a mental disease or defect. Defendant thus cannot assert a defense of incapacity to form a *156specific intent.... the exclusion of this testimony [of alcohol abuse] was proper because Missouri law precludes a defense of voluntary intoxication. § 562.0076 RSMo 1986.
Woltering, 810 S.W.2d at 587-88.
The proffered testimony of Dr. McCarty was that the psychosis of Mouse, while the result of substance abuse, predated the ingestion of drugs or alcohol at the time in question. This was the evidence missing in Woltering and Elam.
“Appellate review of a motion court’s disposition of a Rule 29.15 motion is limited to a ‘determination of whether the findings and conclusions of the [motion] court are clearly erroneous.’ Rule 29.15k.” Kuhlenberg v. State, 54 S.W.3d 705, 707 (Mo.App.2001). “A motion court’s findings and conclusions are clearly erroneous only if the reviewing court firmly believes a mistake was made after it has reviewed the entire record.” Id. “To prevail on a claim of ineffective assistance of counsel, the movant must be able to show that ‘counsel’s performance was deficient and that this deficient performance prejudiced the movant.’ ” Id.
The essence of the findings and conclusions which formed the basis of the motion court’s denial of Appellant’s motion is as follows:
Movant’s position is based on an erroneous assumption; to wit that his attorney should have been able to convince the court the law as declared by the applicable cases is erroneous. In support of his position he called Delaney Dean, a psychologist and an attorney, along with William Flieschaker, mov-ant’s counsel at the time of trial and on appeal. Dean testified, as would Dr. McCarty if allowed to testify at trial, that movant suffered from a psychosis voluntarily induced by methamphetamine use, and that the statute 552.101, R.S.Mo. required his exoneration because he suffered from a mental disease or defect and, therefore did not have the necessary intent to commit the crime. She [Dr. Dean at the Motion 29.15 hearing] relied upon Shipman, supra, despite the fact it is not the law in this state. Counsel for movant, William Flieschaker, testified he did not cite the case to the court, but explained the case was not controlling authority at the time, or today.
The findings and conclusions of the motion court are clearly erroneous. The finding that Flieschaker “explained the case [Shipman] was not controlling authority at the time, or today” is factually wrong. At the motion hearing, Flieschaker distinguished McGreevey and stated that Ship-man would have been appropriately cited to the trial and appellate courts, although he did not do so.
Contrary to the finding of the motion court, the fundamental principle of Ship-man is good law. As stated above, it has been followed by the cases and is incorporated in the criminal instructions. The state has cited no authority Shipman does not correctly state the law and independent research reveals none.
As stated, it was the strategy of counsel to establish Appellant was not guilty by reason of mental disease or defect. There was evidence of the utterly bizarre conduct of Appellant before, at the time of and after the assault upon his friend. There was no motive for that attack. The admission of the testimony of Dr. McCarty was essential to that defense. The clearest authority for the admissibility of that testimony is Shipman. Yet counsel did not cite that case to the trial court or to the appellate court.
“To prevail on an ineffective assistance of counsel claim, a movant must ‘show that *157counsel’s representation fell below an objective standard of reasonableness.’ ” Moss v. State, 10 S.W.3d 508, 511 (Mo.banc 2000) (quoting Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 2064, 80 L.Ed.2d 674 (1984)). “A reasonable probability is a probability sufficient to undermine confidence in the outcome.” Lyons v. State, 89 S.W.3d 32,39 (Mo.banc 2001).
Shipman and the fundamental principle stated therein are cited under § 552.010, RSMo and the appropriate headings in the Missouri Digest. This authority could have been found with reasonable research. If that authority had been cited to the trial court, there is a reasonable probability the testimony would have been admitted. Considering the evidence of erratic behavior and lack of motive, there is a reasonable probability the defense would have been accepted by the jury. If that authority had been cited to the appellate court, the court would have had to distinguish or follow it.
By indirection it has been held that counsel’s failure to cite Shipman was ineffective assistance:
Appellant contends he was denied effective assistance of counsel at trial because they were unaware and failed to assert what appellant urges as a viable defense under § 552.010, V.A.M.S.: “drug abuse with psychosis.” (footnote omitted) The Missouri standard for establishing ineffective assistance of counsel is whether “there has been such failure on the part of the attorney that defendant has not had a fair trial.” (citations omitted) For the omission to constitute ineffective assistance of counsel appellant must show the suggested defense was one which trial counsel could have legitimately asserted on his behalf. He has not so shown. Drug abuse, absent psychosis, is not a defense under § 552.010; therefore, psychosis is the determinative factor. It is clear his trial attorneys considered the possibility of mental disease or defect, including psychosis, and after diligent effort concluded none was present. The best available evidence, the psychiatric evaluations, support the conclusion that Boyer was not psychotic when he committed the crime. The point is without merit, (emphasis added)
Boyer v. State, 527 S.W.2d 432, 437 (Mo.App.1975).
In Mouse, the rejected testimony was that Appellant was psychotic. Counsel failed to cite to the court the most persuasive statement to establish the admissibility of that evidence. In effect, counsel failed to effectively assert a viable defense under § 552.010.
I am firmly convinced that a mistake has been made and that Appellant did not have effective assistance of counsel within the meaning of Rule 29.15. I would reverse the decision of the motion court.
."While drunkenness is no defense, and does not mitigate the offense, and while temporary insanity immediately resulting from voluntary intoxication does not discharge any one of his responsibility, on the other hand, long continued habits of intemperance, producing permanent mental disease amounting to insanity, or, as the instruction says, so weakened and impaired the mind that one committing an offense has not enough mind at the time to know right from wrong, relieves the party, we apprehend, of responsibility under the law. Insanity of this sort, and thus produced, is the same in law as insanity arising from other causes.” State v. Riley, 100 Mo. 493, 13 S.W. 1063, 1064 (1890).
"If the defendant was insane at the time of firing the fatal shot which resulted in the death of the deceased, and was unable to distinguish between right and wrong in the commission of the act which resulted in death, then it can make no difference as to how or in what manner his insane condition was produced.” State v. Porter, 213 Mo. 43, 111 S.W. 529, 531 (1908).
