Defining Consent Answer

How is consent defined?

The term “consent” means the affirmative, unambiguous and voluntary agreement to engage in a specific sexual activity during a sexual encounter which can be revoked at any time.

Consent cannot be given by an individual who:

  • is asleep or is mentally or physically incapacitated either through the effect of drugs or alcohol or for any other reason, or
  • is under duress, threat, coercion or force.

Consent cannot be inferred under circumstances in which consent is not clear including, but not limited to:

  • the absence of an individual saying “no” or “stop”, or
  • the existence of a prior or current relationship or sexual activity.

Okla. Stat. tit. 21, § 113.

Does the definition require "freely given consent" or "affirmative consent"?

Yes. The term “consent” means the affirmative, unambiguous and voluntary agreement to engage in a specific sexual activity during a sexual encounter which can be revoked at any time. Okla. Stat. tit. 21, § 113.






Capacity to Consent Answer

At what age is a person able to consent?

16 years old. Okla. Stat. tit. 21, § 1111(A)(1).

Does difference in age between the victim and actor impact the victim's ability to consent?

Yes. A person under the age of 18 may have sex with someone over the age of 14 with his or her consent. Okla. Stat. tit. 21, § 1112.

Does elderly age impact the victim’s ability to consent?

No

Does developmental disability and/or mental incapacity impact the victim’s ability to consent?

Yes. Rape in the first degree includes an act of sexual intercourse involving vaginal or anal penetration where the victim is incapable through mental illness or any other unsoundness of mind, temporary or permanent, of giving legal consent. Okla. Stat. tit. 21, § 1111(A)(2).

Does physical disability, incapacity or helplessness impact the victim’s ability to consent?

Maybe. If a victim is incapacitated, this may classify as being unconscious, which would then qualify as rape (see below). If not, then the answer is no.

Rape is an act of sexual intercourse involving vaginal or anal penetration accomplished with a male or female within or without the bonds of matrimony who may be of the same or the opposite sex as the perpetrator where the victim is at the time unconscious of the nature of the act and this fact is known to the accused. Okla. Stat. tit. 21, § 1111(A)(5).

Does consciousness impact the victim’s ability to consent?

Yes. Rape is an act of sexual intercourse involving vaginal or anal penetration accomplished with a male or female within or without the bonds of matrimony who may be of the same or the opposite sex as the perpetrator where the victim is at the time unconscious of the nature of the act and this fact is known to the accused. Okla. Stat. tit. 21, § 1111(A)(5).

Does intoxication impact the victim’s ability to consent?

Yes. The definition of rape includes an act of sexual intercourse involving vaginal or anal penetration accomplished with a male or female within or without the bonds of matrimony may be of the same or the opposite sex as the perpetrator where: (1) the victim is incapable through mental illness or any other unsoundness of mind, whether temporary or permanent, of giving legal consent; (2) the victim is intoxicated by a narcotic or anesthetic agent, administered by or with the privity of the accused as a means of forcing the victim to submit; or (3) the victim is at the time unconscious of the nature of the act and this fact is known to the accused. Okla. Stat. tit. 21, § 1111(A)(2), (4), (5).

Does the relationship between the victim and actor impact the victim’s ability to consent?

Yes. Rape includes an act of sexual intercourse involving vaginal or anal penetration accomplished with a male or female within or without the bonds of matrimony who may be of the same or the opposite sex as the perpetrator:

  • where the victim is under the legal custody or supervision of a state agency, a federal agency, a county, a municipality or a political subdivision and engages in sexual intercourse with a state, federal, county, municipal or political subdivision employee or an employee of a contractor of the state, the federal government, a county, a municipality or a political subdivision that exercises authority over the victim, or the subcontractor or employee of a subcontractor of the contractor of the state or federal government, a county, a municipality or a political subdivision that exercises authority over the victim. Stat. tit. 21, § 1111(A)(7).

Defenses Answer

Is consent a defense to sex crimes?

Yes. See Denham v. State, 192 P. 241 (1919) (“where sexual intercourse is voluntarily had by an unmarried female within the age of consent, a prosecution for rape cannot be maintained”).

Is voluntary intoxication a defense to sex crimes?

No. See Kitchen v. State, 69 P.2d 411 (Crim. Ct. App. 1937) (“The principle is everywhere recognized that voluntary intoxication is no justification or excuse for crime, and is no excuse for rape”).

No act committed by a person while in a state of voluntary intoxication shall be deemed less criminal by reason of his having been in such condition. Okla. Stat. tit. 21, § 153.
