Incorrect “Knowingly” Instruction in SIWOC Is Not Reversible Absent Prejudice When Consent Is the Only Disputed Fact

1. Introduction

Green was convicted by a Missoula County jury of sexual intercourse without consent (SIWOC) under § 45-5-503(1), MCA, arising from an early-morning assault alleged by S.D., a 75-year-old longtime family friend who described Green (age 30) as a “surrogate son.” Green testified the sexual intercourse occurred but claimed it was consensual. The State’s proof included S.D.’s detailed account of force and resistance and a SANE examination documenting “significant genital trauma.”

On appeal, Green raised two interrelated issues: (1) ineffective assistance of counsel for failing to request/secure the correct “knowingly” instruction (or object to an incorrect one), and (2) entitlement to plain error review of the instructional error. The core question was whether the conceded instructional mistake warranted relief given the record and the defense theory.

2. Summary of the Opinion

The Supreme Court of Montana affirmed. It acknowledged the trial court gave an incorrect definition of “knowingly” for SIWOC—using the “specific fact/high probability” formulation rather than the “conduct-based” formulation required for SIWOC. Even so, the Court held Green failed to show prejudice:

• Ineffective assistance: Green’s claim failed under the prejudice prong of Strickland v. Washington because, given the jury necessarily credited S.D.’s account of nonconsensual force, the jury necessarily found the mental state required by the proper instruction as well.
• Plain error: For the same reason—no meaningful prejudice and overwhelming evidence establishing the conduct-based mental state—plain error review was not “necessary” to prevent a miscarriage of justice under State v. Trujillo.

3. Analysis

A. Precedents Cited

Standards for IAC and when direct appeal is appropriate.

• State v. Walter — supplied the de novo standard for reviewing ineffective assistance claims (mixed law/fact).
• State v. Secrease (citing State v. Rodriguez) — framed the gateway question whether IAC claims should be heard on direct appeal or reserved for postconviction relief, and recognized that failure to seek the correct “knowingly” instruction can be reviewable directly when “no plausible justification” exists.

Jury-instruction review and prejudice threshold.

• State v. Kirn (citing State v. Dunfee) — stated the general test: whether instructions, as a whole, “fully and fairly” instruct the jury on applicable law.
• Romo v. Shirley — provided the abuse-of-discretion standard for a trial court’s decisions on instructions.
• State v. Bryson (citing State v. Deveraux) — emphasized that even when there is a mistake, reversal requires a showing that the defendant’s substantial rights were “prejudicially affected.” Bryson also supplied the practical sequencing principle: if one Strickland prong fails (often prejudice), the court need not reach the other.

“Knowingly” in SIWOC: conduct-based requirement.

• State v. Hamernick (quoting State v. Azure) — reiterated the obligation to instruct the jury on “knowingly” in the context of the particular crime and held SIWOC is “conduct-based,” requiring an “awareness of conduct” instruction. It relied on State v. Deveraux for the conduct-based characterization.
• State v. Deveraux — anchored the doctrinal point that SIWOC requires the conduct-based mental state definition, not a result-based or fact-knowledge definition.

IAC constitutional framework.

• Whitlow v. State — tied the right to counsel to the Montana and United States Constitutions and adopted the Strickland v. Washington two-part test in Montana practice.
• Strickland v. Washington — provided the governing deficiency-and-prejudice structure and the Court’s instruction to resolve claims on prejudice when dispositive.
• State v. Jefferson — stated the “but for counsel’s errors” probability-of-a-different-result requirement for prejudice.

Plain error limits.

• State v. Long (citing Unified Industries, Inc. v. Easley) — reiterated the general rule against reviewing unpreserved claims.
• State v. Trujillo (citing State v. Dahlin) — supplied the Montana formulation of plain error: discretionary review of unpreserved error only when necessary to avoid a miscarriage of justice, resolve fundamental fairness concerns, or protect the integrity of the process.
• State v. Stratton — confirmed de novo review of whether plain error review should be exercised.
• State v. Mitchell — cautioned plain error is reserved for “extraordinary circumstances.”

B. Legal Reasoning

The Court’s reasoning turned on a tight connection between (i) the nature of SIWOC’s mental-state element and (ii) what factual question the trial actually presented to the jury.

1) The instructional error was real and identifiable.
SIWOC requires proof that the defendant “knowingly has sexual intercourse with another person without consent” (§ 45-5-503(1), MCA). Under § 45-2-101(35), MCA, “knowingly” has three distinct definitions depending on whether the statute focuses on conduct/circumstance, result, or knowledge of a particular fact. Relying on Hamernick and Deveraux, the Court reiterated that SIWOC is “conduct-based,” so the correct instruction is the “awareness of conduct/that the circumstance exists” form.

Yet the jury received a different definition (Jury Instruction No. 12): “aware of a high probability of the fact’s existence,” i.e., the “particular fact” variant in § 45-2-101(35), MCA. The Court treated that mismatch as clear error under existing SIWOC instruction caselaw.

2) The error did not prejudice this defendant on this record.
Even when counsel fails to secure the proper instruction, Green still had to show prejudice under Strickland v. Washington and State v. Jefferson. The Court concluded he could not, because the verdict—given the way the case was tried—necessarily reflected findings that satisfied the correct conduct-based mental state anyway.

• Green’s defense was not “I did not understand what I was doing” or “I accidentally crossed a consent boundary”; it was “she verbally consented.”
• S.D.’s testimony, if believed, described prolonged resistance, force, and statements by Green (“been planning this for a long time”), making it essentially impossible to reconcile with Green lacking awareness that the intercourse was occurring without consent.
• Thus, by convicting, the jury necessarily accepted S.D.’s account and rejected Green’s “yes”/consent account, which in turn necessarily established the “awareness of conduct” mental state required for SIWOC.

The Court distinguished State v. Hamernick on precisely this axis: in Hamernick, the victim initially consented to some contact, and the disputed issue was whether the defendant “knowingly” crossed into nonconsensual intercourse; the wrong instruction there directly “eroded” the defense. Here, the dispute was binary—consent versus force—and the jury’s acceptance of force made the mental-state question functionally noncontroversial.

3) No plain error review because no fundamental-fairness crisis.
For plain error, the Court applied State v. Trujillo: the appellant must “firmly convince” the Court an unpreserved error implicates a fundamental right and that review is necessary to prevent a miscarriage of justice or protect judicial integrity. Because the Court found the error non-prejudicial for IAC purposes and saw “overwhelming evidence” supporting the conduct-based mental state, it held Green failed that burden and denied plain error review.

C. Impact

Because the decision is expressly noncitable and nonprecedential, its formal impact is limited. Practically, it illustrates several recurring dynamics in Montana SIWOC litigation:

• Instructional accuracy remains mandatory in principle but relief remains prejudice-driven in practice. Even clear deviation from the required SIWOC “knowingly” instruction may not yield reversal if the factual findings implicit in the verdict necessarily satisfy the correct standard.
• Defense theory selection matters for prejudice. A “consent actually occurred” theory may make mental-state instruction errors less likely to be outcome-determinative than a “mistaken belief / boundary-crossing” or “initial consent then withdrawal” theory (as illustrated by the Court’s contrast to State v. Hamernick).
• Plain error is not a backstop for routine instructional mistakes. The Court again signaled (through Trujillo, Mitchell) that plain error remains exceptional and closely tied to concrete unfairness, not merely legal incorrectness.
• Trial counsel risk management. Despite the affirmance, the Court’s acknowledgement of “clear” error underscores that SIWOC cases require careful alignment with § 45-2-101(35), MCA and the conduct-based instruction mandated by Hamernick/Deveraux.

4. Complex Concepts Simplified

• SIWOC (“sexual intercourse without consent”): A felony under § 45-5-503(1), MCA. The State must prove intercourse occurred and the other person did not consent, and that the defendant acted with the required mental state.
• “Knowingly” has multiple statutory meanings: Under § 45-2-101(35), MCA, “knowingly” changes depending on what the crime focuses on:
  • Conduct-based: aware of one’s conduct / that the circumstance exists.
  • Result-based: aware it is highly probable one’s conduct will cause a result.
  • Particular fact: aware of a high probability a specific fact exists.
  For SIWOC, Montana cases say the correct one is conduct-based.
• Ineffective assistance of counsel (IAC): Under Strickland v. Washington, the defendant must show (1) deficient performance and (2) prejudice—i.e., a reasonable probability the outcome would have been different absent the error.
• Plain error review: A discretionary appellate safety valve for unpreserved issues, used only when needed to avert a manifest miscarriage of justice or protect the integrity/fairness of the process (State v. Trujillo).
• Prejudice versus “the court made a legal mistake”: Appellate relief typically requires more than showing the instruction was wrong; it requires showing the wrong instruction likely affected the verdict.

5. Conclusion

State v. P. Green applies established Montana law to hold that a concededly incorrect SIWOC “knowingly” instruction does not warrant reversal—either through ineffective assistance or plain error—when the trial’s decisive question is consent and the jury’s guilty verdict necessarily reflects acceptance of evidence showing the defendant’s awareness of nonconsensual conduct under the correct conduct-based standard. While nonprecedential, the decision reinforces a practical message: SIWOC instruction errors are evaluated through the lens of prejudice, and the defense theory and factual posture will often determine whether an error is outcome-determinative.
