Example of the Substantial Capacity Test

17 February, 2016 - 11:05

Loreen has been diagnosed with psychosis and spent most of her life in a mental hospital. While at the mental hospital, Loreen made friends with many of the patients and health-care personnel. From time to time, Loreen would play jokes on these friends. Most of these “jokes” consisted of putting her antidepressants into their food. Loreen was always reprimanded and often sternly punished for these escapades. After her release from the mental hospital at age twenty-one, Loreen falls in love with Aidan, a man who works in a bookstore near her apartment. Loreen decides to make Aidan fall in love with her by feeding him a magic potion, which she concocts out of a mixture of her antidepressants. Loreen buys a book from Aidan and casually asks if he would like her to buy him a coffee. Aidan shrugs and says, “Sure, but I don’t have a break for another two hours.” Loreen offers to bring him the coffee. Before bringing the drink to Aidan, she puts her “magic potion” in it. While Aidan is sipping the coffee, Loreen declares her love for him. She then states, “I know I shouldn’t have, but I put a love potion in your coffee. I hope it doesn’t hurt you.” Aidan becomes seriously ill after drinking the coffee and is hospitalized.

Loreen claims she is not guilty for battering Aidan by reason of insanity. If Loreen is in a jurisdiction that recognizes the substantial capacity test, she may be successful with her claim. Loreen has a mental disease or defect, psychosis. Loreen’s statement to Aidan indicates that she lacks the substantiacapacity to appreciate the criminality of her conduct. Note that if Loreen were in a M’Naghten jurisdiction, her statement “I know I shouldn’t have” could prove her awareness that her conduct was wrong, defeating her claim. In addition, Loreen’s behavior at the mental hospital indicates that she lacks the substantial capacity to conform or control her conduct. Even after a lifetime of being punished over and over for mixing her meds together and putting them in other people’s food or drink, Loreen still does it. Lastly, in a substantial capacity jurisdiction, testimony from Loreen’s friends at the mental hospital may be admissible to support her claim of insanity, and her lack of ability to “appreciate” the criminality of her conduct.
