(dissenting). In this state, by statute, when a defendant in a criminal case is found not guilty by reason of insanity at the time of an offense, he is committed to a state treatment facility until “. . . he may safely be discharged or released without danger to himself or others. ...” 1 The claim here is that this statute violates both equal protection of the law and due process of law. Analysis of such challenge requires initial analysis of the purpose of such insanity acquittal commitment.
Purpose of commitment. What public purpose is served by such commitment of a defendant found not guilty by reason of insanity? The purpose served is twofold: (1) Protection of the public; and (2) treatment and rehabilitation of the defendant.2 More is involved than treating the sick until well.3 Not only is therapy *626for the defendant involved, but also “. . . proper custodial handling so that the community is protected from individuals who may be dangerous to other persons.” 4 It is this factor of protecting the public safety that places the “. . . emphasis upon confinement until the public safety justifies release . ...” 5 Realizing the twofold objective of the commitment, this court has made clear the “. . . primary importance of the public safety factor involved in the automatic confinement of a defendant acquitted on the grounds of insanity . ...” 6
Status of defendant. When a defendant on a criminal charge has been found not guilty by reason of insanity, what has happened? Our court has said that: “When a mentally ill person engages in offensive conduct made punishable by law, society is faced with the question whether at the time of engaging in the offensive conduct the accused was dominated or affected by the mental illness to so substantial a degree that society cannot, in good conscience, hold him responsible for the conduct as a crime, i.e., punish him. ...” 7 The answer to that question, we have held, is that “. . . [t]he legislature and the judiciary, by making general rules, and the jury by its verdict in a specific case must, in combination, provide the answer. . . .” 8 That answer, measuring the degree of relationship between the mental illness of the defendant and his offensive conduct, is a legal *627and not a medical concept.9 In the case before us, the petitioner asserted such legal defense of insanity and was found not guilty by reason of such insanity. He thus became a member of what has been termed “an exceptional class of people — people who have committed acts forbidden by law, who have obtained verdicts of ‘not guilty by reason of insanity.’ ” 10 It is a class or category that is distinct and different from persons committable in civil commitment proceedings for purpose of treatment only.11 It is a class or category also distinct and different from those who are found incompetent to stand trial in judicial proceedings,12 or those, nearing the end of a *628prison term, for whom civil commitment is sought solely for the purpose of treatment until recovery.13
Provisions for release. It is the . . public safety requirements for his release . . .” '14 along with the “. . . nontreatment factors involved in his commitment . . .” 15 that sharply distinguish the purpose of an insanity acquittal commitment from a civil commitment. The statute governing civil commitment proceedings provides that “. . . the person is committed to a hospital for treatment until recovered . . .” 16 and that “. . . [recovery from mental illness is the sole test for release. ...” 17 In fact, under certain circumstances, a person civilly committed may be released before he is fully recovered from his mental illness.18 It is the dif*629fering statutory provisions concerning release or discharge that help establish the nature and purpose of the commitments involved, and the reasonable basis for distinguishing between them. As we stated in Treglown, it is “. . . [t]his emphasis upon release [in civil commitment proceedings] as soon as recovery or the welfare of the patient permits [that] establishes the nature and purpose of the confinement: treatment for the illness involved.” 19 Not so with the petitioner here, for, as in Treglown, “. . . He was found not guilty by reason of insanity and was committed to the Central State Hospital for the protection of the public and for his rehabilitation and treatment, if possible.” 20 (Emphasis supplied.)
Equal protection of law. The petitioner’s contention is that only by some equivalent of civil commitment proceedings could he constitutionally be committed to a state treatment facility following his insanity acquittal. It is without merit. The equal protection clause disapproves only irrational and arbitrary classifications.21 Equal protection of the law . . does not require that all persons be dealt with identically, but it does require that a distinction made have some relevance to the purpose for which the classification is made. . . .” 22 The difference in procedures for civil commitment and the insanity acquittal commitment are warranted by the *630obvious differences in the primary purpose of the commitments involved. Exactly as this court concluded in the Schopf Case on the precise point involved, the writer would conclude that: “. . . The classification made by the legislature in the instant situation between civil commitment and criminal commitment is neither irrational nor arbitrary, and, in fact, is perfectly reasonable. . . .”23 As was appropriately said in Schopf, . . Concern for the general safety of the community requires at least this much. . . .” 24
Counsel for petitioner disagrees, apparently viewing the United States Supreme Court decision in the Jackson Case 25 as washing away the foundation of our court’s holding in Schopf on the equal protection issue. Neither the facts nor the holding in Jackson warrant any such conclusion. In Jackson, the high court dealt with incompetency to stand trial. The petitioner there was a mentally defective deaf mute,26 committed to a mental hospital “. . . solely on account of this incapacity to proceed to trial . . . .” 27 He was there confined for three and one-half years, and medical testimony was that he never would be able to proceed to trial.28 Under these *631circumstances,29 the high court held that the mere filing of criminal charges, no more, did not warrant confining the petitioner for “. . . more than the reasonable period of time necessary to determine whether there is a substantial probability that he will attain that capacity [to proceed to trial] in the foreseeable future. . . .” 30 The commitment statute there involved required a showing of dangerousness, and the court held that “. . . the pending criminal charges are insufficient to establish it, and no other supporting evidence was introduced. . . .” 31 Jackson is to be distinguished from Schopf and the case before us by the purpose of the commitments involved and the status of the petitioners involved, as well as by the absence in the Jackson situation of the public safety factor.
In Jackson, the opinion cites the Baxstrom holding that “. . . a state prisoner civilly committed at the end of his prison sentence . . . was denied equal protection when he was deprived of a jury trial that the State made generally available to all other persons civilly committed. . . .” 32 In Baxstrom, the court said that “. . . there is no conceivable basis for distinguishing the commitment of a person who is nearing the end of a penal term from all other civil commitments.” 33 Then, in Jaek-*632son, the court commented that: “. . . The Baxstrom principle also has been extended to commitment following an insanity acquittal . . . 34 This brief observation of lower court extensions of the Baxstrom holding is not to be ballooned into a high court mandate against automatic commitment in insanity acquittal situations. Such informational comment does not delineate in any manner the nature or extent of the extension made by lower courts nor does it mandate that their example be followed.
Reluctance to escalate a mention into a proscription is strengthened by reference to the three cases cited. In one, the Bolton Case,35 an earlier case, Ragsdale v. Overholser36 justifying immediate commitment in insanity acquittal cases to protect the public, is considered overruled.37 In a second case cited, the Lally Case,38 the same Ragsdale v. Overholser decision is cited, followed and its reasoning termed “sound.” 39 In the third case, the Cameron Case,40 the proposition that one acquitted by reason of insanity “. . . presumably constitutes a greater danger to the public than those civilly committed . . .” 41 is stated to be the basis for congressional adoption of the *633statute involved, and eases are cited in which such justification “. . . has found expression . . 42 with Ragsdale v. Overholser included. Ragsdale v. Overholser holds those who have obtained verdicts of not guilty by reason of insanity to be “an exceptional class of people” treated differently from persons who have not committed offenses or obtained verdicts of not guilty by reason of insanity.43
Due process of law. The “. . . nontreatment factors involved in his commitment . . 44 and the “. . . public safety requirements for his release . . 45 are relevant to petitioner’s claim that commitment following insanity acquittal denied due process. They are a reminder that the petitioner was found not guilty of the commission of a criminal offense solely on his asserted defense of being insane at the time of commission of the offense.46 It is such nontreatment factors and such public safety requirements for release that establish the basis and need for what in Schopf was termed “. . . proper custodial handling so that the community is protected from individuals who may be dangerous to other persons.” 47 In the Lally Case,48 heretofore discussed, the emphasis *634upon the need to protect the public is evident in the, court’s refusing1 to declare unconstitutional a New York State statute providing for automatic commitment following an insanity acquittal verdict. In refusing to strike down the statute, the court said: “. . . We see no reason why a man who has himself asserted that he was insane at the time the crime was committed and has convinced the jury thereof should not in his own interest and for the protection of the public be forthwith committed for detention, examination and report as to his sanity.” 49 (Emphasis supplied.)
In Lally, in upholding the constitutionality of the statute providing for automatic commitment of defendants found not guilty by reason of insanity,50 the court placed emphasis upon the opportunity provided the persons committed to “. . . challenge the validity of his continued detention . . . .” 51 It noted that, under its insanity acquittal law, as under ours, the person committed “. . . may make, to the court by which he was committed, an application for his release or discharge . . . .” 52 It noted that, under their statute, as is the case under ours, the person committed can at any time “. . . ask for a hearing as to his present condition. . . .” 53 It noted that the petitioner before it did not ask for such a hearing, just as the petitioner in the case before us has not, but instead “. . . stood on his contention that his original and continued detention was *635illegal because of the alleged unconstitutionality of the statute.” 54 In Lally, the state appellate court did read. into the statutory provisions for such applications and hearings “. . . a provision for a jury trial of these issues, if appellant so requests. . . .” 55 The petitioner in the case before us already has such right to jury trial on application for re-examination.56 (In fact, he already has had three such re-examination hearings.) In rejecting the due-process challenge to the Wisconsin law, we give weight to the right to petition for re-examination of status and mental condition that is afforded to persons committed following insanity acquittals.
The person committed following an insanity acquittal verdict may petition the court for re-examination of his mental condition and a determination of whether he may safely be released without danger to himself or others at any time after such commitment. As was said in Schopf, . . the prisoner adjudicated not guilty by reason of insanity can initiate proceedings to be reexamined and perhaps released the moment he arrives at the Central State Hospital. . . 57 The person found not guilty by reason of insanity and consequently committed is “. . . sent to Central State Hospital, but with the right to petition for an examination the minute he arrives. . . .” 58 As Schopf puts it, . . When he petitions for the examination, he gets it.” 59 This aspect of the Wisconsin insanity acquittal commitment law pro*636vides adequate process to the petitioner here, and others in his same category. So, exactly as Sehopf concluded in precisely the same situation, the writer would hold the procedures legislatively provided in this state to he “. . . constitutionally adequate to satisfy the requirements of due process . . . .” 60
Finding of dangerousness. This dissenting opinion has stressed what this court has termed “. . . [t]he primary importance of the public safety factor involved in the automatic confinement of a defendant acquitted on the grounds of insanity . . . .” 61 The importance of this public protection factor is also emphasized in the reference in Jackson v. Indiana to a federal statute, 18 USC 4247, applicable on its face to convicted criminals whose federal sentences are about to expire and by judicial interpretation to defendants incompetent to stand trial. This statute “. . . permits commitment if the prisoner is (1) ‘insane or mentally incompetent’ and (2) ‘will probably endanger the safety of the officers, the property, or other interests of the United States. . . .’”62 The Jackson decision notes that a person committed under this section “. . . must be released when he no longer is ‘dangerous.’ ” 63 It notes that, in Greenwood,64 it had upheld even a pretrial commitment under this statute of a defendant who had met all three conditions, but had done so only because “. . . the District Court had in fact . . . found specifically that Greenwood would be *637dangerous if not committed . . .” 65 and, accordingly, “. . . Greenwood was entitled to release when no longer dangerous . . . .” 66 While the high court is discussing here a commitment of a defendant found incompetent to stand trial, it clearly states that the Greewwood commitment was sustained “. . . only upon the finding of dangerousness. . . .” 67
In the case of an insanity acquittal commitment, the writer would hold the element of dangerousness to others to be supplied by the fact of an acquittal solely on the basis of insanity, with the public entitled by that fact alone to commitment with the right of immediate re-examination assured the person committed and confinement and treatment mandated until the person committed “. . . may safely be discharged or released without danger to himself or others. . . 68 However, the writer sees the statute strengthened against future challenge by the majority’s requiring that the same jury which finds a defendant not guilty by reason of insanity at the time of the offense also answers whether or not the defendant, at the time of the verdict, is insane or dangerous to himself or others. If the jury that found the defendant insane at the time of omission of the offense were to find such defendant sane and no danger to himself or others at the time of verdict, the dual basis for and purpose to be served by commitment to a treatment facility would be specifically negatived. If the jury found that such insanity-acquitted defendant was either presently insane or dangerous to himself or others, not much would be added except the buttressing of the statute against a possible constitutional challenge based on some expansion and extension of what was said in the Green*638wood Case. However, certainty is the goal of the judicial process, and particularly so in the criminal field. So the writer accepts as a proper and prudent procedural requirement under the insanity acquittal statute the majority requirement that the jury, if it finds the defendant not guilty by reason of insanity, also be required to answer whether or not it finds that such defendant, at the time of the verdict, is either insane or presents a danger to himself or others.
This long enough journey ends with the writer concluding: (1) The Wisconsin insanity commitment law does not deny either equal protection or due process of law; and (2) the added requirement that, where a jury finds a defendant not guilty by reason of insanity, it also determine whether such defendant is insane or dangerous to himself or others at the time of the verdict is a proper and prudent procedural requirement.

It directs confinement until society is reassured that reccurence of insanity or mental irrespon*626sibility will not result in acts which but for insanity or mental irresponsibility would be crimes.”
