¶ 1 Nephi Joseph Kemper appeals his conviction for sexual assault, a class 2 felony in violation of Arizona Revised Statutes (“A.R.S.”) section 13-1406. We conclude the jury was improperly instructed about an element of the offense, even though the jury instruction tracked the Recommended Arizona Juiy Instruction (“RAJI”) regarding sexual assault. The erroneous instruction, coupled with the prejudice we discuss in a memorandum decision filed July 12, 2011, requires that we vacate Kemper’s conviction and remand for a new trial.
DISCUSSION
¶ 2 A jury found Kemper guilty of sexual assault in violation of A.R.S. § 13-1406(A). That statute provides:
A person commits sexual assault by intentionally or knowingly engaging in sexual intercourse or oral sexual contact with any person without consent of such person.
¶ 3 Kemper assigns error to the final jury instruction regarding sexual assault, which reads:
The crime of sexual assault requires proof that the defendant:
1. Intentionally or knowingly engaged in sexual intercourse or oral sexual contact with another person; and
2. Engaged in the act without the consent of the other person.
The trial court defined “knowingly” and “intentionally” for the jury. It did not, however, instruct jurors regarding the mens rea applicable to the “without consent” element of the charged offense.
¶ 4 Although the final instruction tracked RAJI 14.06.01, the State concedes that it “erroneously omitted reference to the mens rea element governing the ‘without consent’ element.” Because Kemper did not object to the instruction below, he has the burden of demonstrating both fundamental error and ensuing prejudice. State v. Henderson,
¶ 5 The final instruction correctly advised jurors that Kemper must have intentionally or knowingly engaged in sexual intercourse or oral sexual contact with the victim. It did not, however, properly instruct on the mens rea applicable to the consent element of the crime. Cf. State v. Witwer,
¶ 6 The challenged instruction constituted fundamental error. See Henderson,
CONCLUSION
¶ 7 Based on the improper jury instruction, and for the reasons stated in our accompanying memorandum decision, we vacate Kem-per’s conviction and remand for a new trial.
Notes
. In the companion memorandum decision, we outline the facts underlying the sexual assault charge. Those facts are not relevant to the narrow legal issue addressed in this opinion.
. The superior court was not asked to instruct jurors about the “without consent” definition contained in A.R.S. 13-1401(5). Whether such an instruction would have cured the deficiency in the sexual assault RAJI is a question we need not decide. Standing alone, the RAJI was clearly inadequate and legally erroneous.
