OPINION
Appeal was allowed to consider a challenge to a jury instruction explaining the verdict of guilty but mentally ill.
By way of essential background, a verdict of guilty but mentally ill is authorized by Section 314 of the Crimes Code, as follows:
(a) General rule. — A person who timely offers a defense of insanity in accordance with the Rules of Criminal Procedure may be found “guilty but mentally ill” at trial if the trier of facts finds, beyond a reasonable doubt, that the person is guilty of an offense, was mentally ill at the time of the commission of the offense and was not legally insane at the time of the commission of the offense.
*347 (c) Definitions. — For the purposes of this section and 42 Pa.C.S. § 9727 (relating to disposition of persons found guilty by mentally ill):
(1) “Mentally ill.” One who as a result of mental disease or defect, lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law.
(2) “Legal insanity.” At the time of the commission of the act, the defendant was laboring under such a defect of reason, from disease of the mind, as not to know the nature and quality of the act he was doing or, if he did know it, that he did not know he was doing what was wrong.
18 Pa.C.S. § 314.
See generally Commonwealth v. Kontaxes,
(a) General Rule. — The mental soundness of an actor engaged in conduct charged to constitute an offense shall only be a defense to the charged offense when the actor proves by a preponderance of the evidence that the actor was legally insane at the time of the commission of the offense.
(b) Definition. — For purposes of this section, the phrase “legally insane” means that, at the time of the commission of the offense, the actor was laboring under such a defect of reason, from disease of the mind, as not to know the nature and quality of the act he was doing or, *348 if the actor did know the quality of the act, that he did not know that what he was doing was wrong.
18 Pa.C.S. § 315. 1
After attacking and repeatedly stabbing his brother’s fiancée while in her bed, Appellant was charged with attempted homicide, aggravated assault, and possession of an instrument of crime. At the ensuing jury trial, Appellant advanced an insanity defense based primarily upon the testimony of a psychiatrist diagnosing psychotic disorder not otherwise specified, see N.T., March 30, 2005, at 87-88, and that of a specialist in environmental medicine to the effect that Appellant suffers from autism, see id. at 34-36. 2 Both experts opined that, although Appellant was capable of understanding that he was stabbing the victim and that such actions could kill her, he was incapable of understanding the wrongfulness of this conduct. See id. at 36, 83, 88-89. On this basis, the defense psychiatrist opined that Appellant was legally insane under an operative definition congruent with Section 315 of the Crimes Code. See id. at 89. In response, the prosecution presented the testimony of a forensic psychiatrist who concurred in the diagnosis of psychotic disorder not otherwise specified, see N.T., March 30, 2005, at 124, 3 but expressed the opinion that Appellant was not legally insane. According to the Commonwealth’s expert, Appellant was, at the time of his offenses, “mentally ill” under the definition set forth in Section 314 of the Crimes Code, because he lacked substantial capacity to conform his conduct to the requirements of the law. See id. at *349 130. Further, relevant direct examination of the Commonwealth’s expert psychiatrist proceeded as follows:
Q Sir, do you disagree with [the defense psychiatrist] at some point?
A Well, you see, we’re both psychiatrists, and we’re clinicians, and we’ve come to the same opinion about the mental state of the diagnosis. Applying that diagnosis to a state of mind — that is a legal test — is where we differ.
[The defense psychiatrist] gives the opinion — and I was listening carefully to him, and he tends to equate knowledge with appreciation. They’re not equated. Knowledge in the test is purely cognitive. That is, does a person know intellectually, does he have the knowledge that what he did was wrong.
[The defense psychiatrist] kept saying he could not appreciate, could not appreciate. Appreciate has a cuhninative or an emotional component that is not cognitive. So when he throws that in there, I get confused because I don’t know if he’s saying he didn’t know what he was doing was wrong or he could not appreciate what he was doing was wrong, and they’re both different.
Appreciation is not the legal test of insanity in Pennsylvania. So my opinion is that he did know what he was doing and he knew what he was doing was against the law, that it was wrong and he could get in trouble for it.
The other thing that [the defense psychiatrist] said, I think, so well is that Mr. Rabold at the time, at the millisecond, at the time that he did this, felt that he had to do it. It was something he had to do. That has to do with volition. It doesn’t have to do with cognition. So that is not the test of insanity in Pennsylvania, but it is the test of mental illness under a concept in Pennsylvania of guilty but mentally ill.
So I gave the opinion, and I still hold it, that at the time that he stabbed his brother’s fiancée that he lacked substantial capacity to conform his conduct to the require *350 ments of law. That’s the test for mental illness short of insanity.
And because he was mentally ill and because he did what he felt he had to do, he really lacked substantial capacity to control his behavior. But he knew what he was doing, and he knew that it was wrong in my opinion.
N.T., March 30, 2005, at 125-26.
On rebuttal, the defense psychiatrist agreed with the legal framework discussed by the Commonwealth’s expert, differentiating between knowledge and appreciation, and testified to his opinion that Appellant both did not appreciate, and also did not know, what he did was wrong at the time of his actions. See N.T., March 30, 2005, at 140.
After the close of the evidence and closing arguments, the trial court opened its charge by explaining the presumption of innocence and the Commonwealth’s burden of proof beyond a reasonable doubt. See N.T., March 31, 2005, at 37-38 (“[I]t is the Commonwealth that always has the burden of proving each and every element of the crimes charged and that the Defendant is guilty of that crime beyond a reasonable doubt.”). The court proceeded to detail the elements of the substantive offenses charged, highlighting the Commonwealth’s burden of proof beyond a reasonable doubt throughout. See N.T., March 31, 2005, at 41 (“In order to find the defendant guilty of attempted homicide, you must be satisfied that the following three elements have been proven beyond a reasonable doubt ...” (emphasis added)); id. at 42 (same, for aggravated assault).
The trial court then indicated that, because Appellant had asserted an insanity defense, in addition to the ordinary general verdicts of guilty or not guilty, the jury was charged with evaluating the appropriateness of two other potential, special verdicts: “not guilty by reason of legal insanity” and “guilty but mentally ill.” The court proceeded to explain:
The verdict of not guilty by reason of legal insanity labels a [defendant as sick rather than bad. It signifies that in the eyes of the law the person because of mental abnormality at *351 the time of the crime does not deserve to be blamed and treated as a criminal for what he did.
The verdict of guilty but mentally ill labels a [defendant as both bad and sick. It means that in the law’s eyes that person at the time of the crime was not so mentally abnormal as to be relieved from blame and criminal punishment for what he did but that he was abnormal enough to make him a likely candidate for special therapeutic treatment. Legal insanity excuses any crime.... A [defendant has a complete defense to an otherwise criminal act if he was legally insane at the time he committed the act....
N.T., March 31, 2005, at
45-46; accord
Pennsylvania Suggested Standard Criminal Jury Instructions § 5.01A(1), (2);
Commonwealth v. Trill,
Therefore, you can find the Defendant not guilty by reason of legal insanity only if you are satisfied beyond a reasonable doubt that he committed the otherwise criminal act charged and you are also satisfied by a preponderance of the evidence that at the time of the act; first, he had a mental disease or defect at the time of the act; second, that as a result of the disease or defect — and here’s where the insanity defense has an either/or, two prongs — he was incapable of knowing the nature of what he was doing.... So first you must find beyond a reasonable doubt, which is the Commonwealth’s burden, that he committed the crimes *352 charged under those elements I gave you for each of the crimes charged before. If you find that, then the burden shifts, and it’s by a preponderance of the evidence that you find those different prongs of the insanity defense, that you look at those different prongs.
N.T., March 31, 2005, at 47-48; accord Pennsylvania Suggested Standard Criminal Jury Instructions § 5.01A(3).
Next, the trial court developed that a verdict of guilty but mentally ill becomes possible when a defendant offers, but fails to prove, a legal insanity defense. See N.T., March 31, 2005, at 49; accord 18 Pa.C.S. § 314. It instructed:
You may return this verdict if you are satisfied beyond a reasonable doubt that’ the Defendant committed the crime alleged and you are also satisfied by a preponderance of the evidence that ... the Defendant, although not legally insane, was mentally ill at the time of the crime.
Id. at 49-50; accord Pennsylvania Suggested Standard Criminal Jury Instructions § 5.01A(6). The court proceeded to quote Section 314 and explain:
Comparing the definitions of legal insanity and mental illness, we can see that they both require a mental disease or defect which is something more than faulty character, personality, temperament or social adjustment. Their definitions differ, however, with regard to the incapacitating effeetness [sic] for legal insanity on the one hand or mental illness on the other.
Legal insanity requires that the [defendant be incapable either of knowing what he is doing, the physical act itself, or of judging its wrongfulness. Mental illness requires only that the Defendant lack substantial capacity either to appreciate the wrongfulness of what he is doing or to obey the law.
Id. at 50-51; accord Pennsylvania Suggested Standard Criminal Jury Instructions § 5.01A(8).
The trial court also admonished that the jurors should apply the law as instructed and should not concern themselves with what would happen to Appellant if found not guilty, in terms *353 of whether he would be set free or whether he would be confined to a mental hospital for treatment. Nevertheless, it stated:
I will tell you, however, that when a [defendant is found not guilty by reason of insanity, legal insanity, he is subject to an immediate court proceeding to decide whether he should be committed to a mental treatment facility. If committed, his commitment should continue until he is no longer dangerous to others or to himself.
I will also tell you that a [defendant who is found guilty but mentally ill may be given any sentence which may be lawfully imposed on any person convicted of the same crime. However, before imposing sentence, the court must hold a hearing and make findings concerning the [defendant's current mental condition and need for treatment.
The law provides that a [djefendant who is severely mentally disabled and in need of treatment at the time of sentencing shall consistently with available resources be furnished such treatment as is psychiatrically or psychologically indicated for his mental illness. The Mental Health Procedures Act in Pennsylvania dictates where and how he will be treated; for example, whether that will be in a prison setting or in a mental treatment facility.
N.T., March 31, 2005, at 52-53; accord Pennsylvania Suggested Standard Criminal Jury Instructions § 5.01A(10), (11).
The trial court then summarized, as follows:
In order to find the Defendant not guilty by reason of legal insanity, you must be satisfied beyond a reasonable doubt that he committed the otherwise criminal act charged, and you must also be satisfied by a preponderance of the evidence; first, that at the time of the act the Defendant had a mental disease or defect; and, second, that as a result of that disease or defect the Defendant was either incapable of knowing what he was doing, or if he did know, he was incapable of knowing that it was wrong. *354 In order to find the Defendant guilty but mentally ill, you must be satisfied beyond a reasonable doubt that the Defendant is guilty of the crimes charged, and you must also be satisfied by a preponderance of the evidence that the Defendant, although not legally insane, had a mental disease or defect at the time of the crime and as a result of that disease or defect the Defendant lacked substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law.
N.T., March 31, at 53-54; accord Pennsylvania Suggested Standard Criminal Jury Instructions § 5.01A(12).
Appellant’s counsel lodged an objection to the instructions, indicating that, because of their preponderance-based approach to the verdict of guilty but mentally ill, they impermissibly permitted conviction based on a quantum of proof less than beyond a reasonable doubt. See id. at 68.
After due deliberation, the jury returned a verdict of guilty but mentally ill on the charges of attempted homicide and aggravated assault and guilty on the charge of possession of an instrument of crime. The trial court conducted a hearing pursuant to the Mental Health Procedures Act, 50 Pa.C.S. §§ 7101-7116, to determine Appellant’s mental health status, see 42 Pa.C.S. § 9727(a), and sentenced Appellant to fourteen to twenty-eight years’ imprisonment, with directions to the Department of Corrections to afford psychiatric and psychological evaluations, as well as any recommended treatment. Appellant filed timely post-sentence motions arguing, inter alia, that the statutes defining legal insanity and the verdict of guilty but mentally ill are unconstitutional and that the jury instructions impermissibly allowed the jury to convict based upon a standard below proof beyond a reasonable doubt, as well as raising sufficiency- and weight-of-the-evidence challenges.
In addressing Appellant’s challenges, the trial court emphasized that, under its instructions, proof beyond a reasonable doubt of all elements of the substantive offenses was a prereq
*355
uisite to the jurors’ consideration of the status of guilty but mentally ill.
4
The court then conducted a detailed review of the evidence presented by the Commonwealth at trial, including the victim’s eyewitness testimony, and concluded that all elements of all substantive offenses involved were established beyond a reasonable doubt.
See id.
at 5-8. In terms of its articulation to the jurors of the insanity and guilty-but-mentally-ill verdicts, the trial court emphasized that its charge conformed to the standard jury instructions, as well as the pertinent decisional law.

at 21-24 (citing

Addressing Appellant’s sufficiency-of-the-evidence claim, the court reasoned that the evidence in toto (expert and lay, including that of the victim, Appellant’s brother, and responding police officers) supported the conclusion that Appellant lacked the substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law, but that he nevertheless was not laboring under a defect of reason such that he was unable to know the nature and quality of his actions.

Commonwealth v. Foster,
The Superior Court affirmed in a published, panel decision.
See Commonwealth v. Rabold,
Concerning Appellant’s sufficiency claim, the panel characterized his argument as asserting that a finding of guilty but mentally ill negates the
mens rea
required for conviction of homicide and aggravated assault.
See id.
at 859. The Superior Court panel found this claim contrary to the logic of
Commonwealth v. Santiago,
[T]he legislature has determined that persons classified as guilty but mentally ill either lack the capacity to appreciate *357 the wrongfulness of their conduct or are unable to conform their conduct to the requirements of the law. However, the General Assembly determined that this classification of individuals is capable of possessing the requisite mens rea for the attachment of criminal responsibility. In other words, those individuals who have been found guilty but mentally ill are both “sick” and “bad” (i.e., criminally responsible).
Rabold,
As to the weight-of-the-evidence claim, the panel referenced the limited appellate standard of review,
see Rabold,
Presently, Appellant develops that the Pennsylvania General Assembly, as well as a number of other legislative bodies in other states, authorized verdicts of guilty but mentally ill in response to public outrage surrounding John Hinckley’s not-guilty-by-reason-of-insanity acquittal after his attempt to assassinate President Ronald Reagan.
Accord Trill,
Appellant posits that, where a defendant asserts an insanity defense, the essential inquiry must be as follows:
1. Whether the Defendant has proven by a preponderance of the evidence that he was insane at the time he committed the criminal offense.
2. If the defendant fails to prove by a preponderance of the evidence that he was legally insane at the time he committed the criminal offense, the jury must then decide whether the Commonwealth proved beyond a reasonable doubt that the defendant was sane at the time he committed the offense which in turn would result in a verdict of guilty, or the Commonwealth must prove beyond a reasonable doubt that the defendant was mentally ill at the time he committed the offense.
Brief for Appellant at 18. Finally, Appellant takes issue with the sick-and-bad rubric employed in the trial court’s charge, contending that it inappropriately injected character matters into the jurors’ calculus. He highlights his policy perspective of emphasizing compassionate care and treatment for mentally ill offenders versus the imposition of penal measures.

Brief for Appellant at 5 (quoting
Trill,
Appellant’s amicus, the Pennsylvania Association of Criminal Defense Lawyers, also contends that Pennsylvania’s unique statutory scheme, and jury instructions utilized by our trial judges, affords no meaningful guidance between the alternatives of not guilty by reason of insanity and guilty but mentally ill. Amicus notes that the American Bar Association, the American Psychiatric Association, and the National Mental Health Association Commission on the Insanity Defense have all declared their opposition to statutes authorizing verdicts of guilty but mentally ill in general. See, e.g., ABA Criminal Justice Mental Health Standards, 7-610, 393-94, Commentary (1988) (indicating that such a verdict “is not a proper verdict at all” and adds a conceptually unjustifiable element to the criminal justice system). Amicus develops that the legal standard embodied in Section 314 to determine the appropriateness of a verdict of guilty but mentally ill derives directly from a proposed legal standard for insanity advocated by the American Law Institute in its Model Penal Code, Model Penal Code § 4.01 (1985). See Brief for Amicus at 11 (asserting that “no other state employs such a scheme— relying on the American Law Institute’s test of insanity, itself an exculpatory test, for its inculpatory [guilty-but-mentally-ill] verdict, and relying on the alternative but mutually inclu *361 sive M’Naughten (M’Naghten) test as its test for legal insanity”). Further, amicus suggests that the distinctions between the tests are subtle and confusing to laypersons. See Brief for Amicus at 11 (“In the hands of a lay jury, ... the difference between guilt and innocence hangs on the ephemeral distinction between what it means to be capable of ‘appreciating’ that one’s act was wrong and ‘knowing’ it was wrong.”); id. at 12-13 (quoting Pa. Legislative Journal, House 1640 (Sep. 21,1982) (reflecting the comment of a legislator that “[Section 314] is an attempt to get around the existing law by deceiving the jury. It will create enormous problems for a jury.”)).
Amicus quotes a common pleas judge and commentator as follows:
Both judges and juries face a Herculean task in distinguishing the differences between the legal definitions of insanity and mental illness ... Any criminal trial judge who has attempted to explain the legal definitions of insanity and mental illness can relate the quizzical looks given by juries when the legal definitions are read to them. Almost by magic, these quizzical looks disappear and the proverbial “light bulb comes on” when the judge explains the import of their verdict. Suddenly, jurors understand that they are being asked to decide whether the Defendant should go free or face incarceration once his mental health treatment ends. In the parlance of the Superior Court, juries decide whether a “sick” person is also “bad” enough to warrant the punishment of jail.
Brief for Amicus at 13 (quoting Bradford H. Charles,
Pennsylvania’s Definitions of Insanity and Mental Illness: A Distinction With a
Difference?, 12 Temp. Pol. & Civ. Rts. L. Rev. 265, 271-72 (2003));
see also id.
at 265, 272 (expressing the sentiment that “[i]n Pennsylvania, the distinction between the definition of mental illness and insanity is merely semantic” and consequently juries “are left to make ‘ends-oriented’ decisions”).
Amicus
also contends that the “sick” versus “bad” terminology utilized by the trial court strips defendants of the presumption of innocence by inappropriately directing jurors to focus on the defendant’s character rather than the
*362
nature of the defendant’s “sickness” and its relationship to his conduct.
See generally Old Chief v. United States,
The Commonwealth for its part, references the strong presumption of constitutionality attending legislative enactments and the burden upon any challenger to demonstrate that the statute is “clearly, palpably and plainly unconstitutional.”
Commonwealth v. Burnsworth,
Appellant’s challenges to the statutory scheme governing verdicts of not guilty by reason of insanity and guilty but mentally ill present matters of law, over which our review is plenary.
At the outset, we agree with Appellant and
amicus
that the matter of deciding who, among the mentally ill, should bear criminal culpability for their acts, and who should not, is a difficult task, as is the fashioning of a workable definition for legal insanity as a condition relieving one who has committed a crime from criminal responsibility.
See generally Clark v. Arizona,
[I]t is clear that no particular formulation has evolved into a baseline for due process, and that the insanity rule, like the conceptualization of criminal offenses, is substantially open to state choice. Indeed, the legitimacy of such choice is the more obvious when one considers the interplay of legal concepts of mental illness or deficiency required for an insanity defense, with the medical concepts of mental abnormality that influence the expert opinion testimony by psychologists and psychiatrists commonly introduced to support or contest insanity claims. For medical definitions devised to justify treatment, like legal ones devised to excuse from conventional criminal responsibility, are subject to flux and disagreement. See infra at 2732-2733; cf. Leland,343 U.S. at 800-801 ,72 S.Ct. 1002 ,96 L.Ed. 1302 (no due process violation for adopting the M’Naghten standard rather than the irresistible-impulse test because scientific knowledge does not require otherwise and choice of test is a matter of policy). There being such fodder for reasonable debate about what the cognate legal and medical tests should be, due process imposes no single canonical formulation of legal insanity.

This is the constitutional framework in which we resolve this case, and we do so with the recognition that the political branch, and not the courts, serves primarily to determine public policy in Pennsylvania.
See Commonwealth ex rel. Pa. Attorney General v. Griffin,
A substantial portion of the difficulties touched upon in Appellant’s and
amicus’s
briefs proceed from the conceptual overlap, and distinction, between rebutting the Commonwealth’s evidence concerning criminal intent as an element of the offense, and contesting the defendant’s moral culpability via an insanity defense. In this regard, on the one hand, the United States Supreme Court has rejected the notion that
mens rea
and insanity, as currently understood, are entirely distinct, so that mental-disease and capacity evidence relevant to insanity is simply irrelevant to
mens rea. Clark,
Although the matter of distinguishing the intent element of crimes from the insanity defense and guilty-but-mentally-ill verdict may entail some subtlety, this appeal is more straightforward than the present briefs portray, because Appellant’s trial objection was very limited. In the first instance, Appellant did not oppose the overall conceptual framework by which the jury was required to determine whether the Commonwealth met its burden of proof with respect to each element of the offenses; was then to proceed to determine whether Appellant met his burden of proof connected with the insanity defense; and if not, was to consider the appropriateness of a verdict of guilty but mentally ill. Indeed, Appellant proposed that very framework in his requested points for charge, derived from standard jury instructions. See Motion for Binding Instructions and Defendant’s Points for Charge ¶ 15. At trial, Appellant also did not assert *367 that the permissibility of the verdict was the result of some improper legislative purpose or criticize the definitions of insanity and mental illness as confusing and unworkable as he and his amicus do now; rather, Appellant proposed those very definitions. See id. 12 Finally, Appellant did not oppose the sick-and-bad rubric embodied in the trial court’s jury instructions (and as also suggested in the standard jury charge); instead, and again, he proposed those instructions verbatim. see id. ¶ 14. 13
The sole contest initiated by Appellant at trial to the jury charge was limited to his assertion that the burden in connection with a guilty-but-mentally-ill verdict must be assigned to the Commonwealth on proof beyond a reasonable doubt.

Robinson,
On the limited issue that is preserved, we agree with the reasoning of the trial court and the Superior Court that the “preponderant evidence” approach taken in Sohmer does not remove the burden from the Commonwealth of establishing each element of a substantive criminal offense beyond a reasonable doubt. As those courts developed, the trial court’s charge repeatedly and consistently placed that pivotal burden with the Commonwealth, and its satisfaction was a prerequisite to the jury’s consideration of the insanity defense and the guilty-but-mentally-ill alternative. In the terms of the Illinois Supreme Court:
jurors’ consideration of these issues [of commission of the offense, insanity, and mental illness] is carefully channeled. Under the [guilty-but-mentally-ill] statutory scheme, the jury does not consider mental illness until it has first decided the defendant’s claim of insanity. Thus, the jury does not determine insanity and mental illness simultaneously. The jury must consider first whether the defendant committed the acts forming the basis for the charged offense, next whether the defendant was insane, and finally whether the defendant was mentally ill. We believe that the sequence in which these issues are resolved by the jury further demonstrates that the defense in a [guilty-but-mentally-ill] case does not have the burden of establishing conflicting propositions at the same time.
*370
Lantz,
Appellant references no federal constitutional authority to support the proposition that the Legislature was required to assign the burden of proof under Section 314 to the Commonwealth, or that it must be satisfied beyond a reasonable doubt. Moreover, Appellant’s references to civil commitment schemes are inapposite, because the referenced schemes subsume the confinement of persons who have never been found to have engaged in conduct meeting the substantive elements of a criminal offense. See, e.g., 50 P.S. § 7304(f).
We understand that the guilty-but-mentally-ill instructions inject into juror deliberations a matter which is not determinative of the defendant’s criminal responsibility or culpability, but rather goes to an aspect of his post-verdict disposition.
Accord Sohmer,
*371 Finally, we agree with Appellant and amicus that there remain real and serious issues concerning the treatment of mentally ill offenders within the criminal justice system. Nevertheless, when viewed both in terms of the limited role ascribed to the courts in such affairs and the narrow scope of the matter properly presented in this appeal, it is clear that this is not the appropriate vehicle to support a broad-based reexamination of the Pennsylvania scheme for determining criminal culpability, insanity, and mental illness.
The order of the Superior Court is affirmed.
Notes
. The statutory definition of insanity codifies the common-law M'Naghten approach. See M'Naghten’s Case, 8 Eng. Rep. 718 (1843); accord 18 Pa.C.S. § 314(d) ("Nothing in this section shall be deemed to repeal or otherwise abrogate the common law defense of insanity (M'Naghten's Rule) in effect in this Commonwealth on the effective date of this section.”). The standard sometimes is referred to as the "right-and-wrong" test. See 21 Am.Jur.2d Criminal Law § 53 (2008).
. Appellant also presented evidence of a long-term history of learning and adjustment disabilities and intervention. See N.T., March 30, 2005, at 31.
. The Commonwealth's expert did not comment on the diagnosis of autism.
. See Commonwealth v. Rabold, No. 389 Crim.2003, slip op. at 5 (C.P. Monroe Apr. 21, 2006) (“In order to sustain the jury’s verdict under the [statutes governing criminal homicide, attempt, and aggravated assault], the Commonwealth must have proven to the jury beyond a reasonable doubt each and every element of the offenses and then, and only then, defense counsel must have proven by a preponderance of the evidence that Defendant was mentally ill during the commission of the offenses.”); id. at 23-24 (“The jury could not consider Defendant’s mental state at the time of the commission of the crime to determine if he was legally insane or mentally ill without first making the determination that he was guilty of the elements of the crimes beyond a reasonable doubt.”).
. The court also declined to disturb the guilty verdict relative to the offense of possession of an instrument of crime, although it perceived some inconsistency with the guilty-but-mentally-ill verdicts. In this regard, it explained that inconsistent verdicts are valid, so long as the evidence is sufficient to support the convictions that the jury has returned.

. See Brief for Appellant at 13 ("Where as here, a sentence of imprisonment becomes the factual reality of a verdict of guilty but mentally ill, a level of proof beyond a reasonable doubt must be assigned to the fact-finder, otherwise Pennsylvania becomes a state of penal incarceration on a standard of proof of less than reasonable doubt in violation of defendant's right to a fair trial under the Fourteenth Amendment Due [P]rocess Clause of the United States Constitution.''); see also id. ("To allow Rabold, or any other defendant so situated, to be found guilty but mentally ill by a preponderance of the evidence is to incarcerate mentally ill individuals on an evidentiary standard less than that which is allowed in civil commitment hearings for those adjudged with mental illness.”).
. Although Appellant utilizes the term "discriminatory,” he does not specifically set forth an equal protection challenge to Section 314. Rather, his constitutional challenge is framed in terms of the entitlement to a fair trial under due process norms.
. Appellant does not invoke the corollary provision of the Pennsylvania Constitution. See Pa. Const, art. 1 § 9.
. The sufficiency-of-the-evidence argument presented in Appellant's brief rests on the premise that the finding of mental illness under Section 314 versus insanity under Section 315 must be based on proof beyond a reasonable doubt. See Brief for Appellant at 30 ("[WJhere as here two expert witnesses agree in psychiatric diagnosis and disagree on upon [sic] the ultimate issue of fact, there is at the very least, the reasonable likelihood that when comparing the two witnesses['] testimony, the evidentiary standard that must be used to impose criminal liability e.g., finding of mental illness under 18 Pa.C.S.A. § 315 must be proof beyond a reasonable doubt with the burden resting upon the Commonwealth."). His weight-of-the-evidence challenge rests on the proposition that the jury instruction "shocks the conscience," because it so confused the jurors that they would not properly weigh the evidence before them. See id. at 31-32. Since it is apparent that these arguments are integrally dependent upon the success of Appellant's challenges to the statutory framework and jury charge, they need not be addressed separately here.
. For example, Appellant’s perspective on the required inquiry is that, where there is a failed insanity defense, the Commonwealth must prove beyond a reasonable doubt that the defendant is sane in order to maintain a verdict of guilt.
See
Brief for Appellant at 18. Appellant references no authority for this proposition, which is contrary to Pennsylvania's statutory scheme and would undermine the presumption of sanity.
See Sohmer,
. Parenthetically, this Court reached a different conclusion under Article I, Section 9 of the Pennsylvania Constitution in
Commonwealth v. Walzack,
. The distinction between "knowledge” and "appreciation” of wrongfulness forming a basis of the distinction between the common-law and Model Penal Code standards for insanity, which was referenced at Appellant's trial by the Commonwealth's expert, has been discussed in various judicial decisions.
See, e.g., United States v. Meader,
. While, because the matter is unpreserved, the present appeal does not call for us to approve or disapprove the sick-and-bad terminology, we observe that it was used in this case, as it was in Trill, as an illustration of more conceptual descriptions of the not-guilty-by-reason-of-insanity and guilty-but-mentally-ill verdicts. Moreover, as directed by the trial court, the jurors were to assess whether the Commonwealth met its burden to prove beyond a reasonable doubt that Appellant committed the substantive offenses before the jurors ever were to consider the sick-and-bad distinction. In such circumstances, the danger that the jurors would take the references, not as they were intended, but as an invitation to determine Appellant's guilt or innocence by reference to his general character is far more remote than the arguments suggest.
. A federal court also made this point in the following terms:
The state has a legitimate interest in having juries decide cases according to the law. The legislature could well have believed that many defendants were being found not guilty by reason of insanity even though they did not satisfy the legal standard for the defense. The difficulty is that lay juries are presented with complicated and to some extent conflicting notions of what renders a person "insane" in legal, psychiatric, and common sense terms. The [guilly-but-mentally-ill] statutes are designed to insure that the jury applies the legal definition of insanity, by underscoring that a person might be “mentally ill” in clinical terms, "crazy” in common sense terms, yet not legally insane.
We believe it is beyond question that the state could instruct a jury that it cannot acquit on the basis of insanity unless the legal test for insanity has been met. We see no additional objection which can be raised because the state chooses to formalize these instructions by providing a separate verdict form.
United States ex rel. Weismiller v. Lane,
. Parenthetically, to our review, with the exception of one intermediate appellate court decision which was reversed on appeal, the verdict has been universally upheld.
See generally Trill,
. To the degree that there is a concern that a jury may be influenced to render a guilty-but-mentally-ill verdict believing that it carries a more lenient sentence, those concerns were mitigated in this case by the trial court’s use of the standard jury instruction describing a defendant’s disposition upon verdicts of not guilty by reason of insanity or guilty but mentally ill.
