​KembaraXtra-Case Law-Broome v Perkins (1987) QBD - Automatism

​Key Legal Principle: This case clarifies the stringent requirements for successfully invoking the defense of automatism, particularly when actions are not wholly involuntary.
Facts of the Case:

• Defendant (D): Charged with driving without due care and attention.
• Driving Behavior: D drove erratically for five to six miles along a familiar route.
• D's Claim: D, a diabetic, asserted he was experiencing hypoglycemia during the driving period and had no memory after the initial moments of his journey.

Court's Decision (Held):

• D should have been convicted.

Reasoning of the Court:

• For the defense of automatism to apply, the defendant's actions must be completely involuntary.
• If, at any point during the erratic driving, D's actions were voluntary, or if D's mind occasionally exerted some control over their limbs, then the actions were not purely automatic.
• Therefore, D was not entitled to the defense of automatism.

Key Takeaways for Study:

• Automatism Defined: A state where the defendant performs physical acts without conscious thought or control, often due to an external factor or internal physical condition (like hypoglycemia in this case).
• Strict Application: The courts apply the defense of automatism very strictly.
• Partial Control is Insufficient: Even fleeting moments of conscious control or voluntariness negate the defense of automatism. The actions must be wholly involuntary for the defense to succeed.
• Burden of Proof: While the prosecution must prove the actus reus and mens rea, the defense usually bears the evidential burden of raising the issue of automatism.
• Relevance to "Driving Without Due Care": This case highlights that even if a medical condition contributes to erratic driving, if there's any demonstrable level of conscious control or voluntary action, the defendant can still be held liable for offenses requiring a lower mental element, like "due care and attention."

​KembaraXtra-Case Law-Burgess (1991) CA - Automatism and Insanity

Key Legal Issue: Distinguishing between non-insane automatism and insanity, particularly in the context of sleepwalking involving violence.
Facts of the Case:

• The defendant (D) attacked his friend.
• D claimed he was sleepwalking at the time and acting unconsciously.
• D sought acquittal based on non-insane automatism.

Trial Court Outcome:

• The jury returned a verdict of not guilty by reason of insanity.

Appeal and Ruling:

• D appealed the verdict.
• Held: The Court of Appeal upheld the trial court's decision.
• Reasoning:
  • Regardless of the specific cause, D's somnambulism (sleepwalking) was deemed an internal cause.
  • An internal cause, by legal definition, constitutes a disease of the mind.
  • Therefore, the verdict of not guilty by reason of insanity was deemed appropriate.
  • The court acknowledged that medical experts may not classify sleepwalking as a "mental disorder" and that sleep itself is normal.
  • However, the court emphasized that sleepwalking, particularly when it involves violence, is not normal behavior.
  • Such an abnormal state arising from an internal factor is considered a disease of the mind for legal purposes.

Key Takeaways for Study:

1. Automatism vs. Insanity: This case highlights the crucial distinction between non-insane automatism and insanity. While both involve a lack of conscious control, the legal distinction hinges on the origin of the involuntary act.
2. Internal vs. External Cause:
   • Internal Cause: Leads to a finding of insanity (e.g., a "disease of the mind" as defined by law). Burgess established that even if medically normal, an internal condition causing unconscious violence falls under "disease of the mind."
   • External Cause: Leads to non-insane automatism (e.g., a blow to the head, a sudden unexpected illness caused by an external event).
3. "Disease of the Mind" - Legal Definition: The legal definition of "disease of the mind" is not strictly tied to medical classifications of mental illness. An internal condition that causes a defect of reason, leading to involuntary actions, can be considered a "disease of the mind" in law.
4. Sleepwalking and Violence: Burgess specifically addresses sleepwalking, ruling that when it involves violence, it is an abnormal manifestation of an internal condition, thus constituting a "disease of the mind."
5. Burden of Proof: In cases of automatism, the defense typically bears the evidential burden to raise the issue. Once raised, the prosecution must disprove it beyond a reasonable doubt. However, if the court finds the automatism to be a result of a "disease of the mind," the defense carries the burden of proving insanity on the balance of probabilities.

​KembaraXtra-Case Law- R v Windle (1952) - M'Naghten Rules and "Legally Wrong"

​This study guide focuses on the key legal principle established in the case of R v Windle (1952), specifically concerning the interpretation of "wrong" within the M'Naghten Rules for the defence of insanity.

Case Name: R v Windle (1952)
Core Legal Issue: Interpretation of the term "wrong" in the M'Naghten Rules.
Facts of the Case:

• Defendant (D): Killed his wife by administering an overdose of aspirin.
• Wife's Condition: Had a history of mental illness and frequently discussed suicide.
• Defendant's Defence: Claimed insanity, specifically a form of "communicative insanity" known as "Jolie à deux." This condition, D argued, arose from prolonged care for his mentally ill wife, leading to his own mental illness.
• Defendant's Argument for Insanity: D contended that, due to his mental state, he did not know his actions were legally wrong at the time.

Key Legal Principle Established (The "Held" Decision):
The court unequivocally held that for a defence of insanity under the M'Naghten Rules, the defendant must not have known that their actions were legally wrong.
Crucial Clarification from Lord Goddard CJ:

• "Wrong" means "contrary to the law."
• It is not sufficient for the defendant to merely believe their actions were "morally wrong."
• The court explicitly stated: "there is no doubt that, in the M'Naghten Rules, 'wrong' means contrary to the law, and not 'wrong according to the opinion of one man'."

Implications for Understanding the M'Naghten Rules:

• Strict Interpretation: Windle demonstrates a strict, objective interpretation of "wrong" within the M'Naghten Rules.
• Focus on Legality, Not Morality: The M'Naghten Rules are concerned with the defendant's understanding of the legal consequences of their actions, not their personal moral judgment.
• High Bar for Insanity Defence: This ruling makes it more challenging to establish an insanity defence, as the defendant must prove they lacked knowledge of the illegality of their actions, rather than just their immorality. Even if a defendant believes their actions are morally justified, if they know those actions are against the law, the insanity defence (on this point) will fail.

How to Study This Case:

1. Memorize the Core Principle: "Wrong" in M'Naghten = "legally wrong."
2. Understand the Distinction: Clearly differentiate between "leg

​KembaraXtra-Case Law-Case: Sodeman (1936)
Key Concept: This case is a crucial illustration of how the M'Naghten Rules, while primarily focused on knowledge, can potentially incorporate the concept of "irresistible impulse" when directly linked to a disease of the mind.

I. Case Summary

• Facts:
  • The defendant (D) abducted the victim (V), strangled her, bound her, and stuffed clothing into her mouth, leaving her for dead.
  • V died from suffocation.
  • D had a history of three similar murders.
• Defense: Insanity.
• Medical Evidence: Adduced to support that D suffered from "irresistible impulses" compelling him to commit these acts.

II. Legal Ruling (Held)

• The court ruled that under the M'Naghten Rules, if a person knew they were doing wrong, but were forced to commit the act by an 'irresistible impulse' that stemmed from a disease of the mind, then the defense of insanity could be relied upon.

III. Analysis and Key Takeaways for Study

1. M'Naghten Rules Foundation: Recall that the core of the M'Naghten Rules states that for an insanity defense to succeed, it must be clearly proved that, at the time of the committing of the act, the party accused was laboring under such a defect of reason, from disease of the mind, as not to know the nature and quality of the act he was doing; or, if he did know it, that he did not know he was doing what was wrong.
2. Irresistible Impulse - A Nuance:
   • Sodeman introduces a critical nuance: while the M'Naghten Rules primarily focus on cognitive (knowing) capacity, Sodeman suggests that an "irresistible impulse" can qualify if and only if it directly results from a "disease of the mind" and compels the act despite the defendant's knowledge of its wrongfulness.
   • This implies that the "irresistible impulse" itself is seen as a manifestation of the "disease of the mind" that effectively overrides the capacity to refrain from the act, even if the wrongfulness is intellectually understood.
3. Connection to "Disease of the Mind": Emphasize that the irresistible impulse is not a standalone defense. It must be a direct consequence of a recognized "disease of the mind." Without this link, the impulse alone would likely not be sufficient for an insanity defense under M'Naghten.
4. Limits and Interpretations:
   • This ruling can be seen as an expansive interpretation of the M'Naghten Rules, acknowledging a volitional (willpower) component alongside the cognitive one, but strictly within the existing framework.
   • It's important to note that the term "irresist

​KembaraXtra-Case Law- Bratty v Attorney General for Northern Ireland (1961)

​This case is a foundational legal precedent in the areas of insanity and automatism within criminal law.
I. Case Background:

• Defendant: Bratty
• Action: Killed a girl by strangulation in his car.
• Defendant's Claim: Suffered from psychomotor epilepsy at the time, arguing he was unaware of his actions.
• Trial Court Outcome:
  • Trial judge refused to allow the defense of insanity to be presented to the jury.
  • Jury convicted Bratty of murder.

II. House of Lords Ruling (Key Holdings):

1. Interchangeability of Defenses: If the defense of insanity is rejected by the jury, the defendant is entitled to raise the defense of automatism as an alternative.
2. Evidentiary Requirement for Automatism: For automatism to be a viable defense, proper evidence must be presented to establish that the defendant was acting under non-insane automatism.

III. Definition of "Involuntary Act" (Lord Denning's Definition):
Lord Denning provided a crucial definition of an "involuntary act" in the context of criminal law:

• "No act is punishable if it is done involuntarily..."
• An "involuntary act" means an act:
  • Done by the muscles without any control by the mind: Examples include:
    • A spasm
    • A reflex action
    • A convulsion
  • Done by a person who is not conscious of what he is doing: Examples include:
    • An act done whilst suffering from concussion
    • An act done whilst sleepwalking

IV. What an "Involuntary Act" is NOT:
Lord Denning also clarified what does not constitute an involuntary act:

• An act is not involuntary simply because:
  • A person does not remember doing it.
  • The defendant could not control their impulse to do it.

V. Study Points & Implications:

• Distinction between Insanity and Automatism: This case highlights the crucial distinction between these two defenses. While both involve a lack of conscious control, insanity stems from a "disease of the mind," whereas automatism can arise from external factors or internal conditions not classified as a "disease of the mind."
• Burden of Proof: The ruling emphasizes the need for "proper evidence" to establish automatism, indicating that this is not an easy defense to prove.
• Consciousness as a Core Element: Lord Denning's definition strongly links involuntariness to a lack of conscious control over one's actions

KembaraXtra-Case Law- Bingham (1991) Case Summary

​Case Name: Bingham (1991) CAKey Legal Concepts:

• Automatism: A state where a person acts without conscious thought or control. It can be a complete defense if it negates the mens rea (guilty mind) of an offense.
• Mens Rea: The "guilty mind" or criminal intent required for most crimes.
• Insanity (M'Naghten Rules): A legal defense where a defendant is not criminally responsible due to a mental disease or defect at the time of the offense.
• Hypoglycemia: A medical condition characterized by abnormally low blood sugar.

Factual Background:

• Defendant (D): Charged with theft of a can of coke and sandwiches from a shop.
• Defense Claim: D, a diabetic, stated that at the time of leaving the shop without paying, he was suffering from hypoglycemia and was unaware of his actions.
• Trial Judge's Ruling: Refused to allow the defense of automatism to be considered by the jury.

Court of Appeal (CA) Decision:

• Holding: The Court of Appeal found that hypoglycemia is not caused by the disease of diabetes itself, but by its treatment (e.g., too much insulin or insufficient food to counterbalance insulin).
• Legal Implication for Insanity: In most cases, hypoglycemia arising from treatment would not lead to the defense of insanity (as it's not considered a "disease of the mind" for M'Naghten purposes in this context).
• Legal Implication for Automatism and Mens Rea: Hypoglycemia arising from treatment could potentially lead to an acquittal on the basis that D lacked mens rea and was acting under automatism. This means the defendant's actions were involuntary and without the required criminal intent.

Core Takeaway for Study:The case of Bingham (1991) is crucial for understanding the distinction between automatism and insanity, particularly in situations involving medical conditions. While the disease itself (diabetes) might be internal, the effect of its treatment (hypoglycemia) can be considered an external factor for the purposes of automatism if it leads to involuntary actions and a lack of mens rea. This allows for the automatism defense to be raised where an insanity defense might not apply.

​KembaraXtra-Case Law-Quick (1973) CA: Automatism vs. Insanity in Diabetic Episodes

​Case Summary:

• Defendant (D): A nurse.
• Offence: Assaulting a patient.
• D's Claim: Amnesia regarding the assault due to a diabetic episode.
• Contributing Factors to Episode:
  • Took insulin (prescribed).
  • Did not eat sufficient food.
  • Consumed significant amounts of whisky and rum.
• Initial Plea: Not Guilty, based on automatism.
• Trial Judge's Ruling: Only the defence of insanity was permissible.
• D's Action: Changed plea to Guilty, then appealed.

Key Legal Issue:
When a diabetic experiences a state of impaired consciousness leading to an offence, is the appropriate defence automatism or insanity? This hinges on whether the cause is an "external factor" or a "disease of the mind."
Court of Appeal (CA) Ruling:

• D was suffering from a mental abnormality caused by hypoglycaemia.
• Crucial Distinction: The hypoglycaemia was not caused by the internal factor of his diabetes itself.
• External Factor: The CA determined the cause was D's use of insulin prescribed by his doctor. This was considered an external factor.
• Resulting Defence: Since the cause was an external factor, it led to a "bodily disorder" and not a "disease of the mind." Therefore, automatism was the appropriate defence.
• Appeal Outcome: Appeal was allowed.

Important Legal Principle (per Lawton LJ):
The court highlighted crucial limitations to the defence of automatism, particularly in cases of self-induced or foreseeable incapacity:

• Self-Induced Incapacity: A state of incapacity that is self-induced will generally not excuse the defendant.
• Reasonably Foreseeable Incapacity: Incapacity that could have been reasonably foreseen as a result of an action or omission will also not excuse.

Examples of Foreseeable Incapacity (from Lawton LJ):

• Taking alcohol against medical advice after using certain prescribed drugs.
• Failing to have regular meals while taking insulin.

Study Notes & Key Takeaways:

1. Automatism vs. Insanity: This case provides a critical distinction.
   • Automatism: An act done by the muscles without any control by the mind, or an act done by a person who is not conscious of what he is doing. Requires an external factor causing a "bodily disorder."
   • Insanity (M'Naghten Rules): A "disease of the mind" leading to a defect of reason, preventing the defendant from knowing the nature and quality of the act, or that it was wrong. Requires an internal factor.
2. Diabetic Episodes:
   • Hypoglycaemia (low blood sugar): If caused by external factors (e.g., incorrect insulin dosage, failure to eat after taking insulin), it can lead to automatism.
   • Hyperglycaemia (high blood sugar): Typically seen as an internal factor (due to the inherent disease process) and may lead to a defence of insanity. (Though this was not the issue in Quick, it's a useful contrast).
3. The "External Factor" Argument in Quick: The prescribed insulin itself was viewed as an external intervention that, when combined with insufficient food, led to the hypoglycaemic state. This is a subtle but crucial point.
4. Limitations to Automatism: The pronouncements by Lawton LJ are vital. Even if an external factor causes the automatism, the defence can be negated if the incapacity was:
   • Self-induced (e.g., intentionally causing the state).
   • Reasonably foreseeable (e.g., knowing the risks of combining alcohol with medication or skipping meals while on insulin).
5. Application to Quick: While the appeal was allowed based on the external factor, Lawton LJ's comments suggest that if D had foreseen the risk of his actions (taking insulin, not eating, drinking alcohol), the defence might have failed. The specific circumstances of foreseeability would be crucial in future cases.

To Study Effectively:

• Understand the core difference between automatism and insanity.
• Focus on the "external vs. internal factor" distinction.
• Memorize the examples provided by Lawton LJ regarding self-induced/foreseeable incapacity.
• Consider how a scenario similar to Quick but with clearer evidence of foreseeability might be decided.

KembaraXtra-Case Law- T (1990) CC - Automatism Defence
I. Case Background

• Defendant (D): Arrested and charged with armed robbery.
• Co-defendants: Two men.
• D's State on Arrest:
  • Passive and indifferent.
  • Limited recollection of preceding events.

II. Subsequent Revelations & Diagnosis

• Prior Trauma: D had been raped three days before her arrest.
• Psychiatric Diagnosis:
  • Post-traumatic stress disorder (PTSD).
  • Dissociative state.
  • Offence committed during a psychogenic fugue.
  • Not acting with a conscious mind or will.

III. Legal Arguments

• Defence: D pleaded automatism.
• Prosecution's Contention:
  • D recalled some events surrounding the crime.
  • Exercised partial control (e.g., using a weapon).

IV. Court's Holding and Rationale

• Novelty of the Case: First instance where rape was the 'external' event causing mental malfunction.
• Sufficiency of Triggering Event:
  • A rape would have a severe effect on any young woman.
  • Therefore, rape would suffice as the external triggering condition.
• Nature of Mental Malfunction:
  • Malfunction due to post-traumatic stress disorder (PTSD).
  • NOT a disease of the mind (crucial for automatism vs. insanity).
• Degree of Control:
  • Acknowledged only partial loss of control throughout the incident.
  • However, D acted "as if she were in a dream."
• Conclusion: The defence of automatism could rightly be put before the jury.

​KembaraXtra-Case Law-Marison (1996) CA - Study Notes on Automatism Defence

​I. Case Summary

• Defendant (D): Diabetic, prone to hypoglycaemic episodes causing loss of consciousness without warning.
• Incident: D's car veered into oncoming traffic, colliding with another car and killing the driver.
• Charge: Causing death by dangerous driving.
• Trial Judge's Ruling: D was aware of the risk of an episode while driving.
• D's Appeal Ground: Judge's ruling was incorrect.

II. Court of Appeal (CA) Holding

• Automatism Defence:
  • D did become an automaton at the time of the accident.
  • However, D could not use automatism as a defence.
• Rationale for Denying Automatism:
  • D was in a dangerously defective state due to his diabetes prior to the accident.
  • D had already committed the offence of dangerous driving before the accident occurred (i.e., by driving while knowing of the foreseeable risk).
  • The hypoglycaemic episode was reasonably foreseeable.
• Conclusion: The trial judge's ruling was correct.

III. Key Legal Principles & Concepts

• Automatism: A state where an individual acts without conscious control. Can be a defence if truly involuntary and not self-induced/foreseeable.
• Dangerous Driving: Driving in a manner that falls far below the standard expected of a competent and careful driver and which it would be obvious to a competent and careful driver that driving in that way would be dangerous.
• Foreseeability of Risk: A crucial element in determining culpability, particularly when a medical condition might lead to dangerous behaviour. If a risk is foreseeable, an individual may be deemed responsible for taking precautions or avoiding activities that could lead to harm.
• Prior Fault / Self-Induced Automatism (Implicit): Although not explicitly stated as "self-induced automatism," the judgment hinges on D's prior knowledge and the foreseeability of the episode, which effectively negates the defence because D was culpable for putting himself in that position.

​KembaraXtra-Case Law- R v Bailey (1983) CA - Self-Induced Automatism
​I. Case Summary

• Parties: D (diabetic) vs. V (victim)
• Facts:
  • D, a diabetic, took insulin and sugar water but ate nothing.
  • Subsequently, D assaulted V.
  • D claimed to have acted in a state of automatism caused by hypoglycaemia.
  • D told police he hit V to "teach him a lesson" for associating with his ex-girlfriend.
• Charge: Wounding V.
• Plea: Not guilty, arguing automatism.

II. Legal Principles & Holding

• Self-Induced Automatism as a Defence:
  • General Rule: Self-induced automatism can provide a defence to a basic intent crime.
  • Exception: This defence is not available if automatism is caused by intoxication.
• Recklessness & Jury's Role:
  • The jury must determine if D's conduct was "sufficiently reckless".
  • This assessment should consider D's knowledge of the likely results of his actions.
• Specific Application to Diabetics:
  • There is no conclusive presumption that it is reckless for a person (e.g., a diabetic) to fail to take food after a dose of insulin.
  • The jury must still evaluate the specific circumstances and D's knowledge.

III. Key Takeaways

• Distinction: Crucial distinction between self-induced automatism from illness/medical condition vs. intoxication.
• Basic Intent: Automatism (non-intoxication) is a potential defence for basic intent crimes.
• Subjective Recklessness: The defendant's knowledge of the potential consequences of their actions is paramount in determining recklessness for self-induced automatism.
• No Automatic Recklessness: The failure to mitigate a known medical condition leading to automatism does not automatically equate to recklessness; it's a matter for the jury.
