(dissenting) .

I respectfully dissent.

The failure of the state trial court to order an evidentiary hearing to determine appellant’s competency to stand trial and its acceptance of his plea of guilty when there was substantial evidence of appellant's incompetency were a denial of due process of law requiring the writ to issue, unless the state court vacates the sentence and permits appellant to withdraw his guilty plea.

The record reveals the following facts. On April 24, 1964, appellant shot and killed his girl friend and shot and wounded her landlady. The shooting fray occurred during a quarrel between appellant and the decedent after she had rejected his marriage proposal. The landlady intervened during the quarrel and threatened to call the police to eject the appellant. He shot her, then turned upon the decedent and shot her twice. Appellant surrendered to the police later in the day.

Appellant, represented by the public defender, was arraigned on May 15, *1187 1964, on charges of first degree murder and assault with a deadly weapon with intent to commit murder. He pleaded not guilty to both charges, but the public defender indicated that the plea might later be changed to not guilty by reason of insanity.

On May 29, 1964, the physician at the County Jail certified appellant to the Detention Ward of the San Francisco County General Hospital for diagnosis and treatment. The jail physician diagnosed appellant as then “suffering from suicidal tendencies.” Appellant was observed, interviewed, and diagnosed by several medical examiners while he was in the hospital. The examiners submitted reports, at least the first two of which were part of the record before the state trial court, each dated June 4, 1964. The first report, signed by two examiners, said, in part: “Threatens to kill self if he is not given death sentence. Had thought of suicide for some weeks prior to his offense. * * * Decided to make one more effort to get her to come back * * * [and] if she wouldn’t he would kill himself. * * * She jilted him again- — and he doesn’t remember what happened next but evidently he killed her instead.” The report ended: “Not presently psychotic, but potential suicide risk.” Another report by a different doctor recited that doctor’s observations and concluded with his impression: “Depression with suicidal tendencies? possible schiz.” A third report said, in part: “Vague & secretive about murder & reasons, seems schizoid & depressed, don’t know if psychotic or not underneath, mild, not cooperative enough with exam & no history available.”

On August 24, 1964, appellant appeared for trial with a private lawyer, Mr. Jack Berman, who had been retained for appellant by his sister. The proceeding that followed was brief and perfunctory. Mr. Berman told the court that he had ■ discussed the matter with the appellant, the district attorney, and the court, and that “we are prepared to make a motion to withdraw the former plea of not guilty for the purpose of entering a different plea to Count 1.” The clerk read the charges from the indictment and asked appellant how he would plead. He responded “guilty,” the only word he spoke during the proceeding. No other questions were put to him. The attorneys stipulated that the plea was to second degree murder, appellant’s motion to withdraw his plea was granted, and the prosecuting attorney’s motion to dismiss the second count was granted. The court thereupon issued an order recommending appellant’s referral to Vacaville medical facility for 90 days for the purpose of obtaining that facility’s recommendations for the institutional disposition of appellant. The court deferred sentencing until Vacaville had acted upon the court’s requested reference, and ordered appellant returned to the County Jail. Four days later the jail physician again committed him to the hospital upon his diagnosis that appellant was suffering from “suicidal tendencies” and was “a definite Suicidal risk.” He was reexamined at the hospital. The report of the examiner concluded with the diagnosis “Reactive depression in obsessive-compulsive personality” with the recommendation that he be institutionalized.

From the hospital on November 4, 1964, appellant wrote to the trial judge. He told the court he wanted to discharge Mr. Berman, and he wanted to represent himself. He offered to plead guilty to first degree murder, “contingent upon the imposition of the death sentence.” He said that he refused to undergo any more medical examinations. On the same day, Mr. Berman appeared in court and recited that he had been informed that Vacaville had agreed to accept appellant. The deputy district attorney requested that appellant be brought down on the 8th of September for removal to Vacaville “just because he is so dangerous to himself.”

On September 8, 1964, appellant again appeared in court. He insisted that there be a “final disposition of my case,” and he renewed his offer to plead *1188 guilty to first degree murder. He repeated his wish to discharge Mr. Berman and to represent himself. He volunteered to the court that his reasons for “entering a guilty plea are not due to the fact that I am suffering from a ‘guilt complex’ or a psychotic desire to be punished. * * * [A]s far as the crime itself is concerned I do not feel any criminal responsibilities since it was an act which was beyond anything I ever intended or consciously did. The reasons for my entering such a plea are of a, let’s call it personal, philosophical nature which I do not wish to disclose, and I believe that is about all, and if now Your Honor would please sentence me and get this matter over with.” He added, “[A]s far as I am 1 concerned I have reached a point in my life at which continuance of my life is no longer desirable and necessary or in any way * * * possible, logically, emotionally and intellectually.” Sentencing, he said, was meaningless and “nothing will prevent me from taking my life when I find a suitable opportunity.”

After listening to those and to similar statements of appellant, the court remarked: “The only thing that concerns me is whether or not that original plea was acceptable from a legal viewpoint.” At this juncture the court turned to Mr. Berman and said: “Now, you have discussed this with me and you have advised me on more than one occasion previous to this time that the medical information that you had was such that there was no basis for a plea of not guilty by reason of insanity, is that so?” [None of the discussions to which the court alluded were reported, and the record provides no clue to the circumstances under which they took place.] Mr. Berman replied affirmatively, and then added: “[B]oth the medical records, which I examined from the County Hospital from his previous commitment back in the latter part of May and the early part of June, plus my own psychiatrist, Dr. Faircloth, both of them indicate that there was no basis whatsoever for an insanity plea. However, I did advise the Court that I felt the man was mentally ill in a medical sense. * * * I feel as a lawyer that the plea was properly entered in terms of the man’s competence in a 1368 proceeding. He understood what he was doing. * * * I think certainly that the commitment and the studies made there [Vacaville medical facility] would indicate whether the legal opinion I have, which is not based on any personal medical knowledge, but on hearsay that I have gathered from the psychiatrists, would confirm whether I am right in saying that the man was fully cognizant of his actions under the provisions of 1368.” The court thereupon committed appellant to the California Medical Facility at Vacaville.

Following his confinement, observation, and treatment at Vacaville, the examiners submitted a detailed report about appellant’s condition, including the following observations: “The amnesia that he claims for the event [murder] is probably quite valid and is characteristic of so-called ‘dissociative reactions’ in which repressed impulses and anxiety is [sic] discharged or deflected into a symptomatic expression which consists of a blotting out of awareness of unpleasant or intolerable realities. This was followed by a period of intense depression and morbid preoccupation with guilt feelings which could only, in his opinion, be atoned for by eliminating himself. The acute phase of this disorder is now past. * * * It must be recognized, however, that he still has an underlying emotional disturbance of considerable magnitude and that if he is to accomplish anything with his life he requires intensive psychiatric treatment.” The doctor recommended probation, “provided he obtains intensive psychiatric treatment. * * *”

On November 20, 1964, appellant was returned for sentencing. The trial court sentenced him to state prison for the term prescribed by law for second degree murder.

After appellant had exhausted all of his state postconvietion remedies, he filed his habeas petition in the District *1189 Court. He was examined by another psychiatrist, Dr. Blinder, shortly before the federal hearing. Upon the basis of his examination of appellant and his review of the record of the 1964 criminal proceedings, together with the hospital and medical reports, Dr. Blinder testified that in his opinion the appellant was mentally incompetent at the time the plea was entered. The notes which Mr. Berman had made after Dr. Fair-cloth had examined appellant in early August 1964 were introduced. The notes were: “Faircloth results. No psych, defense — Very disturbed. Poss. quite crazy. Hyper-rational man. Consid. suicide potential. Might kill someone else. Does have some awareness of fact he might kill again. Superior man. Can’t know what is going on in his head. Doesn’t know if psychotic or not. Very disturbed. Diff. to exam. 90 day Vacaville — ” [Periods added.]

The District Court, in denying the petition, said: “While petitioner expressed his desire to be sentenced to capital punishment for his crime, attempted suicide several times, and was considered extremely depressed and mentally ill by all who observed him, these facts were not such as to present a substantial doubt as to petitioner’s competency to proceed when at the same time petitioner was acting rationally, speaking lucidly, a psychiatric report from San Francisco County Hospital described him as ‘presently sane (but depressed),’ [exhibit references omitted] Mr. Berman had indicated to the sentencing judge the fact that petitioner had been examined by a psychiatrist and that from both the psychiatrist’s and Mr. Berman’s points of view there was no problem with petitioner’s competency to proceed, and the petitioner himself was vigorously protesting any suggestion that he was incompetent.

The District Court’s conclusion that the failure of the state trial court to order an evidentiary hearing on the issue of defendant’s capacity to stand trial was not a violation of due process rests on assumptions of law that are contrary to the controlling principles of law stated in Pate v. Robinson (1966) 383 U.S. 375 , 86 S.Ct. 836 , 15 L.Ed.2d 815 and Rhay v. White (9th Cir. 1967) 385 F.2d 883 .

Those principles can be summarized as follows: An evidentiary hearing on the issue of a criminal defendant’s competency to stand trial is constitutionally compelled at any time during his trial in which there appears “substantial evidence” that the defendant is incompetent. Such “evidence” is not confined to testimony or exhibits formally introduced at the trial. It includes all information properly before the court indicating a defendant’s mental illness, including, for example, the trial court’s observations of the defendant’s demeanor and conduct, medical reports contained in defendant’s file, and reports of probation officers. In determining the substantiality of evidence of incompetence for the purpose of triggering a competency hearing, the trial court must disregard any evidence tending to prove competency and must assume the truth of the evidence indicating incompetency. The trial court cannot weigh the evidence, determine credibility of witnesses, nor resolve conflicts in the evidence until the evidentiary hearing on the competency issue has concluded. 1

In Pate the United States Supreme Court overturned an Illinois murder conviction because the state trial court failed sua sponte to hold an evidentiary hearing on the issue of Robinson’s competency to stand trial. The evidence of incompetency was introduced at Robinson’s murder trial primarily for the purpose of supporting Robinson’s insanity defense. Some of Robinson’s relatives and a family friend testified to his erratic conduct several years before trial. His mother stated her opinion that he was presently insane. There was introduced a record of a mental hospital to which he had been committed and from *1190 which he had been released as restored some seven years before trial. As against this evidence of incompetency, there was introduced a stipulation between Robinson’s lawyer and the prosecuting attorney that a named doctor, if called as a witness at trial, would testify that in his opinion Robinson “knew the nature of the charges against him and was able to cooperate with counsel when he examined him two or three months before trial." ( 383 U.S. at 383 , 86 S.Ct. at 841 .) As revealed by the trial court record, Robinson participated actively and alertly in the conduct of his trial. The Illinois Supreme Court, affirming the conviction, held that the trial court was not compelled on its motion to order a hearing on Robinson’s capacity to stand trial, because the evidence did not raise sufficient doubt about his then competence. Thereafter a federal district court denied Robinson’s habeas petition without an evidentiary hearing. The Court of Appeals reversed, and the cause came before the Supreme Court on certiorari. The Court agreed with the Court of Appeals that the failure of the trial court to order a sanity hearing was a deprivation of due process. No evidentiary hearing in the federal court was required because the state trial record on its face disclosed enough evidence to have compelled the trial court to interrupt the homicidal trial for a hearing on his then competency to stand trial. Robinson’s rational behavior during the trial and the stipulation that the examining psychiatrist would testify that Robinson was sane enough to be tried could not be relied upon to excuse the trial court’s failure to order a competency hearing.

Thus, Pate teaches that the role of the federal habeas court is limited to an examination of the proceedings before the trial court upon the trial of the offense for which the defendant was convicted. If substantial evidence of incompetency to stand trial appears on the face of that trial record, there is no need for an evidentiary hearing. There are no facts for a federal habeas court to find, because the question is not: Was the defendant then competent? The question is: Was there substantial evidence in the record before the trial court that the defendant was then incompetent? That question is a question of law to be decided solely from the record before the trial court. In determining that question, the federal habeas court cannot weigh the evidence of competency against the evidence of incompetency to find support for the trial court’s failure to order a competency hearing.

However, when there was evidence of incompetency presented to a trial court that was not made a part of the trial court record, an evidentiary hearing is necessary to reconstruct the record. This is the situation in Rhay v. White (9th Cir. 1967) 385 F.2d 883 . On the face of the record of White’s trial there were hints that he was incompetent to stand trial. But much of the information before the trial court relating to the issue was not in the record. 2 The missing items consisted of the trial court’s personal observations of White’s erratic behavior and of off-the-record discussions between White’s counsel and the trial court. An evidentiary hearing was held on White’s federal habeas petition for the purpose of ascertaining the full record before the trial court. In the Rhay situation the federal court was required to find facts, but the factual findings were limited to a determination of what happened during White’s trial. Once those facts were found, the federal habeas court was presented with the identical question of law stated in Pate . 3

*1191 In both Pate and Rhay a court reviewing the decision of the federal habeas court is not bound by the lower court’s conclusion upon the ultimate issue of law, but in the Rhay situation, it is bound by the usual intendments indulged in favor of the factual findings of the lower court.

The Pate and Rhay cases are to be distinguished from a case in which, on collateral attack, a defendant contends that he was in fact incompetent to stand trial, but no substantial evidence of his incompetency was presented to the trial court. (E. g., Smith v. United States (9th Cir. 1959) 267 F.2d 210 ; Robinson v. Johnston (9th Cir. 1941) 118 F.2d 998, 1001 , vacated and remanded on other grounds (1942) 316 U.S. 649 , 62 S.Ct. 1301 , 86 L.Ed. 1732 , rev’d on other grounds (9th Cir. 1942) 130 F.2d 202 ; Sanders v. Allen (1938) 69 App.D.C. 307 , 100 F.2d 717 .) Under the latter circumstance, the function of the court conducting the proceeding on collateral attack is to decide the fact of competency or incompetency. That function could rarely, if ever, be performed without an evidentiary hearing. The petitioner in such a case bears the burden of proving the fact of incompetency to stand trial. (See Butler v. United States (8th Cir. 1967) 384 F.2d 522 , cert. denied (1968) 391 U.S. 952 , 88 S.Ct. 1854 , 20 L.Ed.2d 865 .)

The record of the state trial court in the case at bench contains substantial evidence that appellant was incompetent to stand trial. This is a Pate case, rather than a Rhay, or competency-in-fact ease. Indeed, the evidence of this appellant’s mental incapacity is far stronger than was the evidence in Pate . The trial record includes medical reports that appellant was suicidal, severely depressed, and possibly schizophrenic. Added to the medical data was appellant’s own conduct — his repeated insistence upon being put to death, his threats to kill himself if he were not executed, and his admission that he had no memory of the shooting. 4 Ability to coop *1192 erate with one’s lawyer and to assist in one’s defense requires more than an ability to express coherently a determination to be put to death. (Dusky v. United States (1960) 362 U.S. 402 , 80 S.Ct. 788 , 4 L.Ed.2d 824 ; cf. Rees v. Peyton (1966) 384 U.S. 312 , 86 S.Ct. 1505 , 16 L.Ed.2d 583 ; Westbrook v. Arizona (1966) 384 U.S. 150 , 86 S.Ct. 1320 , 16 L.Ed.2d 429 .)

The majority opinion attempts to excuse the patent constitutional error in several ways, none of which withstands critical examination.

First, the majority opinion implies that appellant was accorded an evidentiary hearing on September 8th, when it states: “on the trial judge’s own motion, and before sentence, a hearing was held on whether appellant’s plea of guilty was voluntarily made and on whether he was suffering from mental incapacity.” That statement is contradicted by the record in the following particulars: (1) the proceeding was not conducted on the court's own motion, (2) it was not directed to appellant’s competency, and (3) it was not an evidentiary hearing. The record shows that the proceeding on September 8 was held in response to either one or both of two events: the request of appellant to change his plea to guilty of murder in the first degree “contingent upon the imposition of the death sentence,” or requests by both the deputy district attorney and appellant’s dismissed counsel to remove appellant to Vacaville. The “hearing” was not for the purpose of inquiring into appellant’s competency; rather, the competency question arose when appellant, then representing himself, explained that he had not pleaded guilty because he thought he had any criminal responsibility in that “it was an act which was beyond anything I ever intended or consciously did,” but he had pleaded guilty for “personal, philosophical” reasons that he did not wish to disclose. The court then expressed doubt that it should have taken his earlier plea. No evidence of any kind was taken on the competency question at that proceeding. It cannot conceivably be characterized as a hearing complying with the requirements of Pate.

Second, the majority emphasizes the trial judge’s referring appellant to the Vacaville diagnostic facility for 90 days pursuant to California Penal Code § 1203.03. The implication is that that referral in some way eliminates the need for a Pate evidentiary hearing. I reject the implication. Referral under § 1203.03 is a posiconviction action under California law, for the purpose of aiding the trial court in determining the disposition of a convicted offender. 5 The *1193 majority states that the trial judge made the referral “to be abundantly certain of his position [concerning appellant’s competency].” But there is nothing in the record to suggest that that was the purpose of the referral, and, indeed, a finding by the district court is to the contrary. 6 Nor did the doctors at Vacaville address themselves to the question of appellant’s competency to stand trial (as their report, supra, clearly shows), and we have no indication that the trial court asked them to consider this question. The report issued by Vacaville cast considerable doubt on appellant’s competency both during August and September and at the time of his November appearance for sentencing. That final appearance before the trial court was in no sense a hearing, evidentiary or othei’wise, on the issue of his competency to be tried or his competency to enter a plea of guilty. It was an appearance for sentencing only. There is no indication, either in the majority’s footnote 3 or elsewhere, that appellant was free to withdraw his plea at that time. And there was substantial evidence that he was incompetent to do so, for the Vacaville report stated that appellant “still has an underlying emotional disturbance of considerable magnitude” and requires “intensive psychiatric treatment.”

Third, the majority opinion makes some point of its characterization of appellant’s guilty plea as the product of a plea bargain. The majority opinion fails to explain how the existence of a plea bargain is in any respect responsive to the constitutional issue presented, and I am unable to supply any explanation. Moreover, the record does not support the majority’s statement insofar as it suggests that the appellant himself participated in or yielded to a plea bargain. There is some indication that appellant’s former counsel participated in a plea bargain, the details of which were never revealed in the record, but there is nothing in the record to support the statement that appellant himself participated in that bargain, if any there were. To the extent that appellant’s participation appears from the record, the indication is that he opposed the plea entered on his behalf.

Finally, the majority refers to the conflicting evidence on the issue of appellant’s competency and concludes that the conflicts were resolved against him by the state trial court and in postconviction proceedings. The state court did not purport to resolve the conflicts in the evidence at the time appellant was tried, or when his plea was taken, or when he was sentenced. Were there an implied finding of competency, that finding would constitutionally fail by reason of the lack of any evidentiary hearing compelled by Pate . The constitutional error cannot be cured by appellant’s failure to persuade the district court on collateral attack that he was in fact incompetent to stand trial. It cannot be cured by reference to “the curb *1194 stone views of a dismissed (and evidently long-suffering) defense lawyer” (United States ex rel. Cole v. Follette, supra, 301 F.Supp. at 1149), or by a judicial diagnosis years after the event that appellant’s multiple suicide attempts and the psychiatric evaluations that he was suffering from psychotic depression evidenced merely normal “deep repentence” for homicide.

The failure to order a hearing on the issue of appellant’s competency to stand trial is not the only constitutional defect in the state proceeding. The second defect, as glaring as the first, is the acceptance of appellant’s guilty plea under the facts shown in this record. 7

At the time the guilty plea was initially taken, the court had before it substantial evidence that appellant was suffering from mental illness and had strong suicidal tendencies; this evidence was amplified by the time of the hearing on September 8, 1964. Nevertheless, the court accepted the plea without first holding an evidentiary hearing on competency. The standards measuring a defendant’s competency to stand trial are not necessarily identical to those defining his competency to enter a plea of guilty. (Compare Dusky v. United States (1960) 362 U.S. 402 , 80 S.Ct. 788 , 4 L.Ed.2d 824 , with Kercheval v. United States (1927) 274 U.S. 220 , 47 S.Ct. 582 , 71 L.Ed. 1009 ; see Westbrook v. Arizona (1966) 384 U.S. 150 , 86 S.Ct. 1320 , 16 L.Ed.2d 429 .) To the extent that they differ, the standards of competency to plead guilty are higher than those of competency to stand trial. A defendant is not competent to plead guilty if mental illness has substantially impaired his ability to make a reasoned choice among the alternatives presented to him and to understand the nature of the consequences of his plea. (Cf. Kercheval v. United States, supra; Rees v. Peyton, supra, 384 U.S. 312 , 86 S.Ct. 1505 .) Because there was strong evidence that appellant fell short of these standards to enter a voluntary and understanding plea, acceptance of the plea was a violation of due process. (E. g., United States ex rel. Crosby v. Brierley (3d Cir. 1968) 404 F.2d 790 .)

I would reverse the order denying appellant’s petition for a writ of habeas corpus with directions to issue the writ, unless the state court entered an order setting aside appellant’s guilty plea and according the appellant an opportunity for trial not later than 60 days after our mandate goes down.

. People v. Pennington (1967) 66 Cal.2d 508 , 58 Cal.Rptr. 374 , 426 P.2d 942 .

. “[T]lie situation here was in any event one, as in Dusky v. United States, 362 U.S. 402 , 80 S.Ct. 788 , 4 L.Ed.2d 824 , where elements were involved that were beyond the information of the trial record, as the hearing , held by the District Court clearly demonstrates.” 385 F.2d at 884 .

. Brizendine v. Swenson (W.D.Mo.1969) 302 F.Supp. 1011 , is illustrative of the proper role of a federal habeas court. *1191 There, the state trial court had ordered a psychiatric examination to determine the defendant’s competency to stand trial for murder. Under the applicable state law, such an order had to be based on a finding that there was “reasonable cause” to believe that the defendant was incompetent. An examination was held, and, satisfied by the doctor’s report, the trial judge decided that no hearing was required and that trial could proceed. A conviction resulted. The district court issued a writ of habeas corpus, holding that the trial court’s order of an examination created alone a tona fide doubt of incompetency under Pate .

The court indicated the proper scope of a postconviction court’s inquiry when a psychiatric examination was not ordered:

Accord, United States ex rel. Cole v. Follette (S.D.N.Y.1969) 301 F.Supp. 1137, 1149 .

. Compare United States v. Silva (2d Cir. 1969) 418 F.2d 328 . Silva had informed an F.B.I. agent at the time of his arrest for bank robbery that he would commit suicide rather than stand trial. A few days after his arrival at the Federal House of Detention, he had swallowed several articles of a possibly dangerous character. He was then taken to the prison ward of the psychiatric division at Bellevue Hospital, where X rays were taken and he received some undisclosed treatment. No determination was made there of his mental condition. A few days later he was returned to the House of Detention, where he subsequently made a confession. At a hearing to determine the voluntariness of the confession, the defendant denied making the confession “and also testified that *1192 he had previously undergone treatment at various hospitals for psychiatric disorders, that he had told the prosecutor about having hallucinatory visions, his use of heroin prior to his arrest, and several attempts to commit suicide.” ( 418 F.2d at 329-330 .) The district judge found the confession was voluntary. Silva was convicted. The Second Circuit reversed:

. In pertinent part § 1203.03 provides:

. “This section [§ 1203.03] is intended primarily as a sentencing aid in oases where probation is a possibility. However, in this case even though the trial judge had no intention of granting probation, he felt that the facilities for treatment at Vacaville were superior to those at regular penal institutions and that some good preliminary treatment and diagnosis would aid petitioner’s adjustment to penitentiary life and start him on an earlier road to recovery.”

. Unlike Boykin v. Alabama (1969) 395 U.S. 238 , 89 S.Ct. 1709 , 23 L.Ed.2d 274 , the record here is not silent on the issue of competency. We therefore need not reach the question of Boykin’s retro-activity.
