    Study Notes

    Insanity

    • Definition: A complete defense to criminal liability where the defendant lacks the understanding of the nature and quality of their actions or that the actions were wrong, requiring a specific mental state at the time of the crime.
    • M'Naghten Rules: The primary insanity test, where a defendant is deemed insane if, at the time of the act, they experienced a defect of reason from a disease of the mind, not knowing the nature and quality of the act or, if they knew it, that it was wrong.
    • Disease of the mind: Crucial, a temporary problem like stress or temporary psychosis isn't enough; the condition must be genuine and relatively enduring.
    • Burden of Proof: The defendant must prove they met the criteria on the balance of probabilities (lower threshold than beyond reasonable doubt).
    • Outcome: A successful insanity plea doesn't lead to immediate release; detention in a mental health facility under the Mental Health Act until safe release is possible.

    Automatism

    • Definition: An act committed without conscious control of the mind, an involuntary action.
    • Types:
      • Insane Automatism: An involuntary act caused by a recognized mental illness, treated as an insanity defense.
      • Non-insane Automatism: Involuntary actions resulting from external factors (e.g., concussion, sleepwalking, drug/alcohol reaction). A complete defense if the defendant wasn't negligent or reckless in causing the involuntary act.
    • Key Distinction: The cause of the automatism differentiates insane and non-insane automatism, with mental illness leading to insanity and external factors leading to non-insane automatism.
    • Examples of external factors: Concussion, sleepwalking, or a reaction to drugs or alcohol.
    • Burden of Proof: The defendant must generally prove involuntary actions on the balance of probabilities.
    • Proof of the involuntary act: The defendant needs to demonstrate the lack of control over their actions.

    Intoxication

    • Voluntary Intoxication: Knowingly consuming substances like alcohol or drugs; generally not a defense to a criminal act.
    • Exceptions: Extreme voluntary intoxication can sometimes negate specific intent, impacting the mental capacity to commit certain crimes.
    • Involuntary Intoxication: Consuming substances without knowledge or consent (e.g., spiked drinks), treated similarly to automatism—generally a possible defense for involuntary actions.
    • Specific and Basic Intent:
      • Specific Intent Crimes: Require a particular mental state (e.g., murder, theft); voluntary intoxication can make a defendant incapable of forming the necessary intent.
      • Basic Intent Crimes: Require recklessness or negligence (e.g., assault); voluntary intoxication is not typically a defense.
    • Evidence and Burden of Proof: The defendant needs to provide evidence to the court regarding how intoxication affected their responsibility for the act.
