Denials of Liability: Intoxication, Automatism, and Insanity Study Notes

Module Overview and Academic Logistics

• Lecture Progression: The module is entering its final stages with three lectures remaining.
  • Week 8: Focuses on "Denials of Liability."
  • Week 9: Focuses on "Defenses properly so-called."
  • Week 10: Consists of a combined revision lecture and a mock exam session.
• House Rules: Students are instructed not to talk during lectures and to keep mobile phones away from their faces to avoid distracting the lecturer and peers.
• Mock Exam Process (Week 10):
  • Content: A mock exam paper consisting of $5$ questions curated from previous exam papers is available on Canvas.
  • Exercise: Students are encouraged to practice these essays under timed conditions.
  • Self-Marking: A self-marking guide will be published after the Week 10 lecture.
  • In-Class Feedback: During the second hour of the Week 10 lecture, the lecturer will live-mark $2$ to $3$ submitted student essays (anonymously if preferred) to provide insight into the marking process and grade boundaries.

Distinguishing Defenses from Denials of Liability

• Technical Legal Meaning: In general parlance and criminal practice, the term "defense" is often used loosely. However, doctrinally, there is a sharp distinction between a defense and a denial of liability.
• Defenses Properly So-Called (Supermeaning Defenses):
  • Definition: These apply when the defendant has committed a crime (the $Actus \, Reus$ ($AR$) and $Mens \, Rea$ ($MR$) are both satisfied).
  • Structure: The crime is committed, but the defendant appeals to a separate set of exculpatory rules.
  • Examples: Self-defense, duress, and necessity.
• Denials of Liability:
  • Definition: These involve the defense arguing that the client simply did not commit the crime because an essential element of the offense is missing.
  • Function: These undermine the elements of the offense itself rather than providing an excuse for a completed crime.
  • Simple Denials: Examples include alibi arguments ("It wasn't me, I was in another country") or arguments of lack of control ("I was asleep").
  • Special Denials: Intoxication, automatism, and insanity are unique because they trigger specific, complex sets of rules once raised.

Constructing Liability through Intoxication

• The Rationale of Prior Fault: As established in the House of Lords case $DPP \, v \, Majewski$, if a person voluntarily consumes a substance that causes them to "cast off the restraints of reason and conscience," they cannot complain if they are held liable for injuries caused in that state. The "prior fault" of becoming intoxicated substitutes for the missing $MR$.
• Basic Application Rules:
  • Intoxicated $MR$ is $MR$: If the defendant acted with the required $MR$ despite being drunk, intoxication is irrelevant to liability.
  • Capacity vs. Reality: Per $Sheehan \, and \, Moore$, the court does not ask if the defendant had the capacity to form $MR$, but simply whether they did form it.
  • Case Example: $Kingston$ (1994): The defendant was drugged by a third party (who intended to blackmail him) and committed indecent assault on a $15 \, year \, old$ boy. Although he was involuntarily intoxicated and lacked usual restraints, the court found he still acted purposefully with $MR$. The House of Lords refused to create a new defense for these circumstances; because $AR$ and $MR$ were present, he was liable.
• Voluntary vs. Involuntary Intoxication:
  • Involuntary: Occurs in cases like drink-spiking. In $Hardie$, the defendant took what he thought was a sedative (Valium) and had an unexpected reaction (arson). No prior fault existed to construct liability.
  • Voluntary: In $Allen$ (1988), the defendant consumed high-strength homemade wine. He claimed he didn't know how strong it was, but the court held it was voluntary because he knew he was consuming an intoxicant.
• The "Dangerous Drug" Category:
  • Legal Definition: A drug is "dangerous" if the law deems that a defendant should know it might lead to unpredictable or dangerous behavior. This is an objective legal test, not a scientific or medical one.
  • Dangerous: Alcohol and most illegal drugs (e.g., LSD in $Lipman$, where the defendant thought he was fighting snakes but killed his partner).
  • Non-Dangerous: Sedatives or medicines (e.g., Valium in $Hardie$, insulin in $Bailey$) are generally non-dangerous unless the defendant has subjective knowledge from prior experience that the drug causes them to lose control.
• Specific vs. Basic Intent Offenses:
  • Specific Intent: Crimes requiring a purposive or ulterior intent (e.g., Murder, Section $18$ wounding, Theft). Voluntary intoxication cannot substitute for missing $MR$; this may lead to an acquittal (or a move to a lesser "basic intent" charge).
  • Basic Intent: Crimes where recklessness is usually sufficient (e.g., Manslaughter, Section $20$, Section $47$, Sexual Assault). Prior fault can substitute for missing $MR$.
  • Case Example: $Heard$ (2007): The defendant rubbed his penis on a police officer's leg while drunk. Because sexual assault was categorized as a basic intent offense, his intoxication did not prevent liability despite the requirement for "intentional" touching.
• Causation and the "Stupidity Defense": Per $Richardson \, v \, Irwin$, the jury must decide if the intoxication caused the lack of $MR$. If a sober person would have made the same mistake (e.g., failing to see the risk of throwing someone off a $12 \, foot$ balcony), the defendant is not liable via intoxication rules.
• Dutch Courage: In $AG \, for \, NI \, v \, Gallagher$, Lord Denning noted that if a person gets drunk specifically to gain the courage to commit a crime, they cannot rely on their subsequent intoxication to deny $MR$, even for specific intent crimes.
• Intoxication and Defenses: Generally, a defendant cannot rely on a mistake caused by voluntary intoxication to satisfy a defense like self-defense.
  • Self-Defense: Must be based on the subjective belief of a sober person.
  • Case Example: $Taj$: The defendant suffered from intoxication-induced psychosis $24 \, hours$ after his last drug use and attacked a man he thought was a terrorist. The court held that this psychosis, being linked to prior intoxication, still fell under intoxication rules, defeating his claim of mistaken self-defense.
  • Outlier: $Jaggard \, v \, Dickinson$: A rare case where an intoxicated mistake was allowed for a statutory defense to criminal damage, though this case is heavily criticized and isolated to its facts.

The Doctrine of Automatism: Voluntariness and Control

• Definition: Automatism describes a state where the defendant's body acts without the control of the mind (spasms, reflexes, convulsions). It is a denial of the requirement for a voluntary act.
• Legal Threshold: The loss of control must be total.
  • Case Example: $Broome \, v \, Perkins$: A diabetic driver who retained some minimal ability to react to stimuli was not in a state of automatism.
  • Case Example: $AG \, Ref \, (No \, 2 \, of \, 1992)$: "Driving without awareness" (a dissociated state) was held not to be automatism because there was not a total destruction of voluntary control.
  • Case Example: $Coley \, (2013)$: The defendant attacked neighbors with a Rambo knife while lurching in a dissociated state. Because he performed complex actions (dressing in camouflage, traveling to the house), it was not a legal state of involuntariness.
• Internal vs. External Cause Distinction:
  • External Cause: (e.g., a blow to the head causing concussion). Leads to Simple Automatism and an unqualified acquittal.
  • Internal Cause: (e.g., epilepsy, sleepwalking, or a blood clot). Leads to Insanity and a qualified acquittal (special verdict).
  • Case Example: $Sullivan$: An epileptic seizure was ruled an "internal cause," meaning the defendant had to plead insanity rather than automatism.
  • Case Example: $Burgess$: Sleepwalking is categorized as insanity because the cause is internal to the defendant's mind/body.
• Psychological Blow: In $T \, (1990)$, a woman claimed she was in a state of automatism caused by the "psychological blow" of being raped $3 \, days$ earlier. While the possibility was left to the jury, the legal grounds for such claims have shrunk due to the strict "total loss of control" requirement.
• Prior Fault in Automatism: Per $Quick$, if the state of automatism was brought about by the defendant's own fault (e.g., a diabetic taking insulin but failing to eat), liability can be constructed for basic intent offenses, provided the defendant subjectively foresaw the risk of becoming automatic.

Insanity and the McNaughton Rules

• Two Applications:
  1. Unfitness to Plead: A procedural issue where the defendant cannot understand the charges or participate in a trial (leads to disposal/treatment).
  2. Insanity at the Time of Offending: Using the condition to deny liability or as a defense.
• The Qualified Acquittal: The verdict is "Not Guilty by Reason of Insanity." Unlike a simple acquittal, this allows the court to order hospital treatment, supervision, or absolute discharge.
• The McNaughton Rules (1843): Derived from the Prime Minister's secretary's killing, these require:
  1. Defect of Reason: More than mere absent-mindedness ($Clarke$).
  2. Disease of the Mind: An internal cause that can be permanent, transient, or intermittent ($Sullivan$, $Kemp$).
  3. Nature and Quality of the Act: The defendant did not know what they were doing (e.g., thinking a throat is a loaf of bread in $Stephen's \, Digest$). This is interpreted strictly; if the defendant understands the basic physical nature of their act, they fail this limb ($Harris$, $Keal$).
  4. Knowledge of Wrongfulness: If the defendant knew the nature of the act, they must show they did not know it was wrong.
• Legal vs. Moral Wrong: In English law, "wrong" means legally wrong.
  • Case Example: $Windle \, (1952)$: The defendant gave his wife $100$ aspirins. Upon arrest, he said, "I suppose I shall be hanged for this." This demonstrated he knew his act was legally wrong, defeating the insanity defense despite his mental illness.
  • Case Example: $Johnson \, (2007)$: Confirmed that understanding legal wrongness precludes the insanity defense, even if the defendant suffers from paranoid schizophrenia.
• Recent Strictness:
  • $Keal \, (2022)$: The court held that even with command delusions (believing one is possessed by the devil), the defense fails if the defendant understands they are harming someone and that harming people is wrong.
  • Dual Test Potential: In $Keal \, and \, Taj$, the court suggested that knowing either the legal or moral wrongness independently might be enough to undermine the defense entirely.
