Oklahoma Whether Victim Was Capable of Giving Legal Consent is a legal concept in the state of Oklahoma. It is an affirmative defense to a charge of rape in the second degree, or rape in the first degree, when the defendant is accused of having sexual intercourse with a victim who was not capable of giving legal consent due to mental illness or mental incapacity. This defense is commonly referred to as the “Incapacitated Victim Defense” in Oklahoma. There are two types of Oklahoma Whether Victim Was Capable of Giving Legal Consent: 1. Mental Illness: Under this defense, the defendant must prove that the victim was suffering from a mental illness at the time of the alleged offense that caused them to be unable to effectively understand the nature of the act of sexual intercourse or to give legal consent. 2. Mental Incapacity: Under this defense, the defendant must prove that the victim was “unconscious, asleep, drugged, or otherwise mentally incapacitated” at the time of the alleged offense and was therefore unable to effectively understand the nature of the act of sexual intercourse or to give legal consent.
