¶1Defendant entered pleas of guilty to two counts of statutory sexual assault
¶2Subsequent to the entry of the plea of guilty, and prior to sentence, defendant asserted a number of constitutional challenges to the various provisions of Megan’s Law. Initially, defendant challenged the registration provisions.
¶3*483Defendant likewise challenges the notification provisions of the law.
¶4The issue we address is the constitutionality of section 9794
¶5With respect to the due process provisions of the Fourteenth Amendment of the United States Constitution, it is held in In re Winship, 397 U.S. 358, 90 S .Ct. 1068 (1970) that proof of a criminal charge beyond a reasonable doubt is constitutionally required. Similarly, pursuant to the due process provisions of Article I, Section 9 of the Pennsylvania Constitution, a conviction cannot be sustained except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime charged, the burden upon the Commonwealth. Commonwealth v. McFarland, 252 Pa. Super. 523, 382 A.2d 465 (1977).
¶6*485The reach and thrust of Winshipwas considered in Mullaney v. Wilbur, 421 U.S. 684, 95 S.Ct. 1881 (1975). In that case, the Supreme Court was considering the homicide statute of the State of Maine which provided murder consisted of an intentional killing whereas the homicide could be reduced to manslaughter upon a showing that the defendant acted in the heat of passion on sudden provocation. However, the statute further provided that the burden of proving that the accused acted in the heat of passion on sudden provocation was placed upon the offender. In applying the Winshipstandard, the Supreme Court held that that statute was in violation of the due process provisions of the Fourteenth Amendment of the United States Constitution. In addressing the contention by the State of Maine that the issue of heat of passion on sudden provocation was not an element of the offense, but rather should be treated as an affirmative defense, the Supreme Court stated as follows:
“This analysis fails to recognize that the criminal law of Maine, like that of other jurisdictions, is concerned not only with guilt or innocence in the abstract, but also with the degree of criminal culpability. Maine has chosen to distinguish those who kill in the heat of passion from those who kill in the absence of this factor. Because the former are less ‘blameworth(y),’ State v. Lafferty, 309 A.2d at 671, 673 (concurring opinion), they are subject to substantially less severe penalties. By drawing this distinction, while refusing to require the prosecution to establish beyond a reasonable doubt, the fact upon which it turns, Maine denigrates the interest found critical in Winship.
“The safeguards of due process are not rendered unavailing simply because a determination may already have been reached that would stigmatize the defendant *486and that might lead to a significant impairment of personal liberty. The fact remains that the consequences resulting from a verdict of murder, as compared with a verdict of manslaughter, differ significantly. Indeed, when viewed in terms of the potential difference in restrictions of personal liberty attendant to such conviction, the distinction established by Maine between murder and manslaughter may be of greater importance than the difference between guilt or innocence for many lesser crimes.” 95 S.Ct. at 1889.
¶7In considering the argument of the State of Maine that the distinctions between murder, voluntary manslaughter and involuntary manslaughter, depend solely on intent, the Supreme Court in Mullaneyopines that an offender could be convicted of felonious homicide and sentenced to life imprisonment unless he was able to prove the requisite heat of passion as the polestar of voluntary manslaughter or recklessness as that of involuntary manslaughter. With respect to this observation, the Supreme Court stated as follows:
“Winship is concerned with substance rather than this kind of formalism. The rationale of that case requires an analysis that looks to the ‘operation and effect of the law as applied and enforced by the state,’ St. Louis S.W.R., Co. v. Arkansas, 235 U.S. 350, 362, 35 S.Ct. 99, 102, 59 L.Ed. 265 (1914), and to the interests of both the state and the defendant as effected by the allocation of the burden of proof.” Mullaney v. Wilbur, 95 S.Ct. 1890.
¶8Thus, Mullaney holds the doctrine of Winshipgoes beyond the mere formalism of determining guilt or innocence but also to those matters relevant to the prosecution having a significant impact upon the liberty rights of the accused.
¶9At first blush, one might conclude that Patterson v. New York, 432 U.S. 197, 97 S.Ct. 2319 (1977) rep*487resented a step back from Mullaney. The court in Patterson, of course, acknowledged the viability of Winship. In addressing the holding of Mullaney, it recognized that the Supreme Court had held that the burden of proof could not constitutionally be placed on the defendant proving by a preponderance of the evidence that the killing had occurred in the heat of passion on sudden provocation as was the law of Maine. The court in Pattersonfurther recognized that the chief justice and Mr. Justice Rhenquist in Mullaney concurred in the result and called attention to the fact that the court did not call into question the holding in Leland v. Oregon, 343 U.S. 790, 72 S.Ct. 1002 (1952) holding that it was not a violation of due process principles to impose the burden upon a criminally accused of proving insanity as a defense to the crime. The court in Pattersonwas considering a New York conviction in which the burden was placed consistent with the law of the State of New York upon the defendant of proving affirmative defense. Thus, Pattersonstands for the proposition that it is not a violation of the Fourteenth Amendment to place the burden of proof of affirmative defenses by a preponderance of the evidence upon the defendant so long as it is understood that all elements of the criminal charge must be proven by the prosecution beyond a reasonable doubt. Significantly, that is likewise the law of Pennsylvania with respect to the due process provisions of Article I, Section 9 of the Pennsylvania Constitution. See Commonwealth v. Stawinsky, 234 Pa. Super. 308, 339 A.2d 91 (1975); Commonwealth v. McFarland, supra,and Commonwealth v. Hilbert, 476 Pa. 288, 382 A.2d 724 (1978). In fact, the due process rights as contained in the Fourteenth Amendment of *488the United States Constitution and Article I, Section 9 of the Pennsylvania Constitution are essentially coextensive. Commonwealth v. Clutter, 419 Pa. Super. 275, 615 A.2d 362 (1992), allocatur denied, 535 Pa. 644, 633 A.2d 149 (1993).
¶10Bearing these principles in mind, the question is then reduced to whether the designation as a sexually violent predator as created by this statute and the mandatory sentencing consequences thereof, fall within the reach of Winshipand Mullaney. We believe that they do. Winshipinvolved a proceeding against a juvenile, and the question was whether the juvenile, in a proceeding for delinquency, was entitled to the due process protections of the Fourteenth Amendment of the United States Constitution placing the burden upon the prosecution of proof beyond a reasonable doubt. The court therein held, that in view of the extreme consequences of incarceration which could result from a finding of delinquency, due process did so require. Similarly, Mullaney reached the same conclusion regarding the extremity of the result where the burden of proof was thrust upon the defendant regarding proof of matters which would constitute, not an affirmative defense, but rather the elements of a lesser offense. Pattersondoes not detract from either of those cases. Under the scheme devised by the legislature in Megan’s Law, the effect of the determination of whether the defendant is a sexually violent predator is extreme. Upon such a finding, as previously noted, on a first offense, the mandated maximum sentence is life imprisonment, and the mandated sentence on the second offense is life imprisonment. Although many of the predicate offenses are felonies of the first degree for which the maximum *489sentence could be 20 years, with respect to prostitution, one of the predicate offenses, a felony of the third degree, the maximum sentence is seven years.
¶11We have no difficulty in determining that this sentencing structure constitutes punishment as the sanction as applied to the individual serves the goals of punishment. Those goals are that punishment serves the twin aims of retribution and deterrence. Retribution and deterrence are not legitimate nonpunitive governmental objectives. U.S. v. Halper, 490 U.S. 435, 109 S.Ct. 1892 (1989). See also, Austin v. United States, 509 U.S. 602, 113 S.Ct. 2801(1993)\Department of Revenue v. Kurth Ranch, 511 U.S. 767, 114 S.Ct. 1937 (1994) and California Department of Corrections v. Morales, 514 U.S. 499, 115 S.Ct. 1597 (1995) which shifted the focus of the law’s purpose to its effect and establishing that the appropriate punishment analysis is flexible and context dependent. These cases were synthesized in Pennsylvania in terms of an ex post facto analysis in Commonwealth v. Gaffney, supra,adopting the analysis of the Third Circuit as the law of Pennsylvania and providing that a measure is punishment if (1) the legislature’s actual purpose is punishment, (2) if the objective purpose is punishment, or (3) if the effect of the statute is so harsh that as a matter of degree it constitutes punishment.
¶12*490A review of the legislative findings and declaration of policy by the legislature in enacting this legislation is instructive. Subsection (a) deals with the legislative findings and declares as a matter of legislative finding essentially that the public for its own protection has a right to be informed of the fact that a sexually violent predator has been released and where he will reside so that appropriate actions for the protection of the community can be taken. Subsection (b) of that section contains the declaration of policy as follows:
¶13“It is hereby declared to be the intention of the General Assembly to protect the safety and general welfare of the people of this Commonwealth by providing for registration and community notification regarding sexually violent predators who are about to be released from custody and will live in or near their neighborhood. It is further declared to be the policy of this Commonwealth to require the exchange of relevant information about sexually violent predators among public agencies and officials and to authorize the release of necessary and relevant information about sexually violent predators to members of the general public as a means of assuring public protection and shall not be construed as punitive.”
¶14Obviously, these legislative findings and declaration of policy address the public notification sections and provisions of this legislation but make no mention of the mandatory sentencing provisions of persons determined to be violent sexual predators. A declaration that these provisions shall not be construed as punitive, aside from the fact that it is self-serving, address only the legislative findings and the declaration of policy all relating to notification but not to mandatory sentencing. It is abundantly clear that this sentencing scheme is punitive aimed at retribution and deterrence, at least *491to the extent that a life sentence would deter this offender from again offending.
¶15McMillan v. Pennsylvania, 477 U.S. 79, 106 S.Ct. 2411 (1986) is somewhat instructive although not directly on point. In that case, the Supreme Court was considering the constitutionality of the Pennsylvania Mandatory Sentencing Law,
“It operates solely to limit the sentencing court’s discretion in selecting a penalty within the range already available to it without the special finding of visible possession of a firearm. Section 9712 ‘ups the ante’ for the defendant only by raising to five years the minimum sentence which may be imposed within the statutory plan. The statute gives no impression of having been tailored to permit the visible possession finding to be a tail which wags the dog of the substantive offense. ” McMillan v. Pennsylvania, 106 S.Ct. at 2417. (emphasis added)
¶16Megan’s Law not only shifts the burden to the defendant but imposes a burden of proof of clear and convincing evidence,
¶17Lastly, the court in McMillancited and distinguished Specht v. Patterson, 386 U.S. 605, 87 S.Ct. 1209 (1967) in which the Colorado scheme of sentencing at issue *493provided conviction of a sexual offense otherwise carrying a maximum penalty of 10 years exposed a defendant to an indefinite term to and including life imprisonment if the sentencing judge made a post-trial finding that the defendant posed “a threat of bodily harm to members of the public, or is an habitual offender and mentally ill.” The court in Spechtas acknowledged by McMillan, required that for such finding, due process principles apply. We believe that they likewise apply here including the due process principle, at the very least, placing the burden of proof upon the Commonwealth.
¶18Defendant also challenges the definition of sexual violent predator as contained in section 9792 of the Act.

Verniero, 119 F.3d 1077 (3d Cir. 1997) wherein the Third Circuit held that the notification provisions of the New Jersey law did not violate the ex post facto or double jeopardy clauses of the United States Constitution. However, that court held that the due process clause would be violated by any notification that occurred without a prior opportunity to challenge the registrant’s classification and notification plan in a hearing at which the prosecutor has the burden of persuasion and must prove his or her case by clear and convincing evidence.

These United States Supreme Court decisions as well as Artway, of course, construe those statutes in terms of due process, double jeopardy, and ex post facto considerations under the United States Constitution. However, the Pennsylvania Constitution with respect to these concepts is co-extensive with the United States Constitution. See Commonwealth v. Gaffney, supra,and Commonwealth v. Mattis, 454 Pa. Super. 605, 686 A. 2d 408 (1996), allocatur denied, 547 Pa. 752, 692 A.2d 564 (1997).
