v.
FRANK N. ABBOTT, Appellant.
No. 8638-7-II.

*331 PETRIE, J.[*]
Defendant, Frank N. Abbott, Jr., appeals an order of revocation of probation and judgment and sentence of confinement for a maximum term of 20 years for the crime of statutory rape in the first degree, RCW 9A.44.070, entered after the trial court denied defendant's motion to withdraw his previously entered plea of guilty. On appeal, he assigns error to the trial court's denial of his motion to withdraw his plea of guilty. His theory is that, because he had never been advised as to the mens rea necessary to prove the crime charged, his plea of guilty was invalid on due process grounds. We find no error and affirm the judgment and sentence.
Defendant's argument on appeal appears to have two separate and distinct facets: (1) the Legislature "failed to establish a mens rea for the crime of statutory rape in the first-degree," RCW 9A.44.070; and (2) defendant was not advised of every essential element of the crime charged, citing State v. Holsworth, 93 Wn.2d 148, 607 P.2d 845 (1980).
Defendant's first contention is absolutely correct. The Legislature, in defining the crime of first degree statutory rape, did not set forth a degree of culpability as an element of the crime.[1] At the time defendant's plea of guilty was accepted, he told the court that he engaged in sexual intercourse with a female less than 11 years of age and that he was over the age of 13 years. Those are all the facts necessitated by the Legislature to establish the crime charged. He contends, however, that at least the element of "knowledge" must be an implied element of statutory rape. We do *332 not agree.
[1] A statute may punish conduct alone, without making any specific degree of culpability an element of the crime. State v. Cleppe, 96 Wn.2d 373, 635 P.2d 435, cert. denied, 456 U.S. 1006 (1981); State v. Stroh, 91 Wn.2d 580, 588 P.2d 1182, 8 A.L.R.4th 760 (1979). When the Legislature fails to specify a given degree of culpability to constitute the activity deemed punishable as a crime, the courts may sometimes find that the statute contains an implied element of specific intent or guilty knowledge before the perpetrator can be said to have committed the crime. State v. Stroh, supra. But the courts will not find an implied element in the face of a legislative intent to the contrary. State v. Cleppe, supra.
[2] In the case at bench, we find no legislative intent to warrant imposition by implication that the perpetrator had to either know that facts which define the offense existed at the time the activity occurred or that he had knowledge of information which would lead a reasonable man to believe that those facts existed. Indeed, we find a contrary intent. RCW 9A.44.030, which provides a statutory defense to the crime charged, expressly provides that, except under specified circumstances which must be proved by defendant under a preponderance of the evidence standard, "it is no defense that the perpetrator did not know the victim's age, or that the perpetrator believed the victim to be older".[2] Thus, lack of knowledge of one of the three statutory elements of the crime, i.e., the victim's age, was expressly deemed not even a defense to the crime charged (except for limited circumstances not pertinent herein). It is patently *333 frivolous to hold, by implication, that an element of the crime is that the accused must have knowledge that he is over the age of 13.
The only other statutory element of the crime charged is the commission of an act of "sexual intercourse with another person." Presumably, defendant's contention is that the Legislature impliedly imposed upon the State the burden to prove that he "knowingly" engaged in sexual intercourse[3] with another person.
Here, we must distinguish between a person's knowledge of which specific acts have been defined by the Legislature as constituting "sexual intercourse" and a person's ability or capacity  at the time he commits those acts  to know that he is in fact performing those acts. Were we to hold that the State has the burden to prove that an accused had knowledge of which specific act or acts have been defined as "sexual intercourse," we would have to say that the State must prove that an accused has precise knowledge of the law. We cannot and do not hold that the Legislature impliedly imposed that burden upon the State. Were we to hold that the State must prove that an accused had the mental capacity or ability to know that he was in fact performing the acts specified, we would be converting a defense burden into a prosecutorial burden. In the absence of a statutory mandate to that effect we refuse to find such a transposition of burdens by implication.
In short, the Legislature has imposed strict criminal liability upon those persons over age 13 who engage in acts of sexual intercourse with persons younger than themselves by *334 2 or more years. The legislative intent is clear. The Legislature has chosen a specific means to combat the social evil of carnal abuse or exploitation of children by persons more than 2 years older than themselves. We will not impose any additional burdens upon the State than those mandated by statute.
Defendant directs our attention to State v. Miller, 30 Wn. App. 443, 635 P.2d 160 (1981), review denied, 96 Wn.2d 1026 (1982), in which the court held that the crime of indecent liberties[4] is a lesser included offense of the crime of statutory rape in the second degree.[5] He contends that, because indecent liberties requires the State to prove that an accused "knowingly causes another person ... to have sexual contact with him or another", necessarily the court in Miller held that the knowledge element is present by implication in the crime of statutory rape. Such a conclusion may be warranted, but the Miller court did not expressly so hold. To the extent that Miller may be so interpreted, we decline to follow it.
The record reveals that defendant was aware of, and told the court that he had performed, all the elements of the crime of first degree statutory rape. There was no basis for the trial court to have granted his motion to withdraw his *335 plea of guilty.
Judgment affirmed.
