Important
- Actus reus and mens rea – The legal system requires two foundational elements for criminal guilt to be established: a wrongful deed (actus reus) and criminal intent (mens rea).
- Dispositions over sentences – Individuals found Not Criminally Responsible on Account of Mental Disorder (NCRMD) receive a disposition overseen by a Review Board rather than a fixed sentence, which the professor explicitly stressed as a critical takeaway to remember.
- Separation of Fitness and Criminal Responsibility – A defendant’s mental state at the time of the trial (fitness) and their mental state at the time of the offense (criminal responsibility) are legally separate issues that have no direct implications on each other.
- Rarity of NCRMD – Only about 1% of annual adult criminal cases raise the NCRMD defense, debunking the common misconception that it is a frequently used legal loophole to avoid prison.
- Voluntary Intoxication and Automatism – Following recent Supreme Court rulings, extreme voluntary intoxication can theoretically be used for an automatism defense if it completely removes mens rea, but alcohol alone will almost never reach this extremely high legal bar.
Core Concepts
- Fitness to Stand Trial: An assessment of whether a defendant, due to a mental disorder, is unable to understand the nature or object of the proceedings, understand the possible consequences, or communicate with counsel.
- Criminal Responsibility (NCRMD): A legal defense arguing that the defendant possessed a mental disorder at the time of the offense that made them incapable of appreciating the nature and quality of the act or knowing that it was wrong.
- Review Boards: Legal bodies consisting of lawyers, psychiatrists, psychologists, and laypersons mandated to oversee the care, dispositions, and potential release of defendants found unfit or NCRMD.
- Dispositions: The specific outcomes for individuals found NCRMD, which include an absolute discharge (if they pose no significant threat to the public), a conditional discharge (release into the community with specific rules), or a detention order (held in a secure psychiatric facility).
- Automatism: Unconscious, involuntary behavior where the person committing the act is completely unaware of what they are doing; it can be classified as non-mental-disorder (resulting in a not guilty verdict) or mental-disorder (resulting in an NCRMD verdict).
- Mental Health Courts: Specialty courts designed to divert defendants with serious mental illnesses out of the traditional criminal justice system and into community-based treatments, typically utilized for minor to moderately serious offenses.
- Psychosis: A cluster of symptoms—including hallucinations, delusions, and disorganized thinking—often resulting from serious mental illnesses like schizophrenia, which is frequently evaluated during forensic assessments.
- Forensic Stigma: Negative public perceptions, biases, and fears regarding forensic psychiatric patients, which are heavily influenced by the sensationalized media reporting of rare, highly violent cases.
Theories and Frameworks
- Criminalization Hypothesis: A perspective suggesting that the deinstitutionalization of psychiatric patients, combined with a failure to provide adequate community mental health services, has led to arrest and incarceration becoming the default response for people with mental illness.
- Criminogenic Risk Perspective: A framework proposing that individuals with serious mental illnesses are overrepresented in the justice system because they experience higher rates of generalized criminogenic risk factors (e.g., unemployment, unstable housing, lack of education, substance use) rather than solely because of their psychiatric symptoms.
- McNaughton Standard: The historical legal framework for insanity derived from 19th-century British law, which established that a defendant must suffer from a disease of the mind that prevents them from knowing the nature of their act or understanding that it was wrong.
Notable Individuals
- Daniel McNaughton: Attempted to assassinate the British Prime Minister in 1843 but killed his secretary instead; his subsequent acquittal due to his mental status shaped modern criminal responsibility laws.
- James Hadfield: Attempted to assassinate King George III in 1800 and was acquitted due to a brain injury, prompting the creation of the early Criminal Lunatics Act.
- Kenneth Parks: A Canadian man who successfully utilized the non-mental-disorder automatism defense after driving 23 kilometers to his in-laws’ house and killing his mother-in-law while sleepwalking.
- Jeffrey Arenburg: A man experiencing paranoid schizophrenia who shot Ottawa sportscaster Brian Smith, representing a high-profile local case often associated with the NCRMD defense.
- Matthew Brown: A defendant in a recent Supreme Court of Canada case who successfully argued that extreme intoxication from magic mushrooms placed him in a state of automatism lacking mens rea.
- Vincent Li: A man who killed a passenger on a Greyhound bus during a state of psychosis, representing a highly sensationalized case that heavily influenced public stigma and legislative changes regarding NCRMD.
- Scott Starson: A physics researcher with bipolar disorder whose case went to the Supreme Court of Canada regarding his competency to make treatment decisions and refuse psychiatric medication.
