Comprehensive Study Guide to Criminal Defences: Intoxication and Self-Defence

Overview of Criminal Defences

When a defendant (D) is charged with a criminal offence, they have two primary options: plead guilty and admit liability, or plead not guilty and contest liability.
Challenging a charge when pleading not guilty can be achieved via three methods: * Challenging the factual basis of the charge (e.g., arguing that the facts are not as the prosecution alleges). * Arguing that one or more elements of the Actus Reus ( $AR$ ) have not been proven by the prosecution. * Arguing that one or more elements of the Mens Rea ( $MR$ ) have not been proven by the prosecution.
Defences are categorized as: * General Defences: Can be pleaded in relation to any crime. * Specific Defences: Can only be pleaded in relation to certain crimes. * Complete Defences: Result in an acquittal. * Partial Defences: Result in a conviction for a lesser offence.

The Nature and Impact of Intoxication

The criminal justice system acknowledges that intoxicants (alcohol and narcotics) alter behavior and states of mind.
Evidence and court reports demonstrate a high correlation between intoxication and criminal activity.
According to the Office for National Statistics ( $ONS$ ), intoxication is a factor in approximately $39\,\%$ of all violent crimes in England and $49\,\%$ in Wales.
Intoxication contributes significantly to public disorder and anti-social behavior across various communities.
In criminal law, a prerequisite for liability is typically foresight of the risk that an act or omission will produce the prohibited consequence.
Theoretically, if foresight is lacking due to intoxication, criminal liability should not follow; however, the law restricts this to prevent an excessive number of defendants from avoiding liability based on high levels of consumption.
Ashworth and Horder ( $2016$ ) observed that the "logic" of the standard doctrines of $AR$ and $MR$ has been subordinated to considerations of "social defence."
Where intoxication induces a state of automatism, the law treats the case as one of intoxication (the cause) rather than automatism (the effect).
For policy reasons, voluntary intoxication is not a defense per se; rather, D can argue that their condition prevented them from forming the requisite $MR$ .

Voluntary Intoxication and the Majewski Distinction

The landmark decision in DPP v Majewski [1977] AC 443 (HL) established the primary rules for intoxication: * Crimes are divided into "offences of specific intent" and "offences of basic intent." * Intoxication is allowed as a "defence" (a denial of fault) for specific intent offences (e.g., Theft, Section $18$ Wounding with Intent). * Intoxication is not a defense for basic intent crimes.
In Majewski, D attacked several people and police officers while voluntarily intoxicated. He argued he could not form $MR$ . The House of Lords held that his recklessness in consuming the intoxicants was sufficient to substitute for the $MR$ of basic intent offences.
R v Taj (2018) reaffirmed long-standing principles: * Self-induced intoxication is not a defense to criminal responsibility. * The principle is founded on the rationale of recklessness, pragmatism, and policy (the need to keep violence under control). * The law would be in contempt if self-induced intoxication excused responsibility; criminal behavior resulting from drugs/drink is a serious menace to society.
The term "specific intent" was first used in DPP v Beard (1920), though it was not initially intended to carry its current weight.

Specific vs. Basic Intent Crimes: Definitions and Classifications

General (Basic) Intent: The intent to commit an act without necessarily intending to achieve a specific result.
Specific Intent: The intent to commit an act and achieve a specific, further result.
Specific Intent Criteria: * Offences that can only be committed intentionally (where recklessness does not suffice). * Offences requiring an "ulterior intent" (intent going beyond the prohibited act). * Examples: Murder; Section $18$ Wounding/GBH with intent; Arson/Criminal Damage with intent to endanger life.
Basic Intent Criteria: * Examples: Common assault; Section $47$ Assault occasioning actual bodily harm ( $ABH$ ); Manslaughter; Assault on a police officer in the execution of duty; Section $20$ Wounding/GBH; Taking a conveyance without authority; Arson/Criminal Damage; Arson/Criminal Damage being reckless as to whether life is endangered; Sexual Assault. * Note: Sexual assault is basic intent notwithstanding that "intentional" touching is a required element.

Key Case Law in Voluntary Intoxication

R v Lipman [1970]: * D took LSD and had a "trip." He struck his girlfriend and stuffed bed sheets in her mouth, suffocating her. He claimed he was unaware of his actions. * The Court of Appeal ( $CA$ ) upheld a conviction for manslaughter (Basic Intent). * Self-induced automatism from a dangerous drug is treated as voluntary intoxication. * The court applied the test from R v Church: whether a sober and reasonable person would foresee a risk. A sober person could foresee that taking drugs carries a risk of harm; thus, taking them is considered grossly negligent and reckless.
Attorney General for NI v Gallagher [1963] (The "Dutch Courage" Rule): * D, described as an aggressive psychopath, bought a bottle of whiskey and a knife with the intent to kill his wife. He drank the whiskey to give himself "Dutch courage" and then carried out the murder. * Ruling: If a person forms the intention to kill and drinks to bolster themselves, they cannot rely on intoxication to deny $MR$ .
R v Heard [2007]: * D assaulted a police officer and committed sexual assault. Sexual assault was held to be a basic intent crime. * The court noted there is no "universally logical test" for distinguishing between crimes; categorization is policy-driven and decided on an offence-by-offence basis.

Criticisms of the Law on Voluntary Intoxication

Violation of Legal Principles: The current law contravenes the maxim actus non facit reum nisi mens sit rea (an act does not make a person guilty unless their mind is also guilty).
Substitution of Recklessness: The Majewski rule assumes that "recklessness" in the ordinary sense (unreasonable conduct/carelessness) is a valid substitute for "recklessness" in the legal sense (subjective awareness or foresight of a specific risk).
The Coincidence Principle: AR and MR should coincide. The recklessness in becoming intoxicated usually occurs much earlier than the commission of the offence.
Burden of Proof: The rule is contrary to Section 8 of the Criminal Justice Act 1967, which states that intent or foresight should be decided by reference to all evidence. Note that Section $8$ specifically does not apply to intoxication cases.
Illogical Distinction: Lord Salmon conceded the specific/basic intent distinction is illogical. The Court of Appeal in R v Wood (1981) also questioned the concepts.
Sexual Offences Paradox: Under Section 3 of the Sexual Offences Act 2003, the $MR$ for sexual assault involves intentional touching (Specific Intent characteristic) and a lack of reasonable belief in consent (Basic Intent characteristic). This creates confusion regarding the categorization of rape and sexual assault.

Involuntary Intoxication: Principles and Core Cases

Involuntary intoxication includes: * Non-volitional consumption (having a drink spiked). * Use of prescription medication in accordance with medical instructions. * Volitional consumption of a "non-dangerous" drug, provided D was not reckless.
R v Hardie [1985]: * D took Valium prescribed for his girlfriend to calm down. Instead, it had an adverse effect, and he set a fire. * Conviction quashed: The court held that taking a sedative (non-dangerous drug) was not inherently reckless. D could not appreciate the risks to property or persons.
Pearson’s Case: Park. J stated that voluntary drunkenness is no excuse, but if a party is made drunk by "stratagem" or the "fraud of another," they are not responsible.
R v Kingston [1995]: * D, who had paedophiliac tendencies, was drugged without his knowledge by a third party. He then performed sexual acts on an unconscious boy. * Ruling: Despite being involuntarily intoxicated, D was held liable because he still formed the requisite $MR$ (the intent was present alongside the intoxication). "A drunken intent is still an intent."
Sheehan and Moore [1975] (The Sheehan Direction): Confirms that intent formed while intoxicated constitutes valid intent for criminal liability.
R v Campeanu [2020]: For a Sheehan direction, there must be sufficient evidence that D claims they failed to form intent due to the state of intoxication.
R v Allen [1998]: If D voluntarily consumes alcohol that happens to be stronger than realized, this remains voluntary intoxication.

Self-Defence, Public Defence, and Private Defence

There is a common law right to defend oneself, others, or one's property.
Force can be used to prevent a crime or to apprehend an offender legally.
Section 3(1) of the Criminal Law Act 1967: Allows the use of such force as is "reasonable in the circumstances" in the prevention of crime or in effecting or assisting in a lawful arrest.
Section 76 of the Criminal Justice and Immigration Act 2008: Provides the statutory basis for self-defence, clarifying areas like "householder cases" and the protection of self/others/property.
The Test for Self-Defence: * Must be for a specified purpose. * Necessity: Subjective test. Did the D honestly believe force was necessary based on their assessment of the situation? (Satisfied even if others would disagree). * Reasonableness: Objective evaluation. Was the amount of force used reasonable based on the facts as the D believed them to be?

The Tests for Self-Defence: Necessity and Reasonableness

Lord Morris in R v Palmer [1971]: Stated that a person being attacked cannot "weigh to a nicety" the exact measure of necessary defensive action. Evidence of "honest and instinctive" action in a moment of anguish is potent evidence of reasonableness.
Mistake: D may be mistaken about the need for force, but the defense is still available if the belief was honest.
Pre-emptive Strike: A person can act before being struck if they believe it is necessary.
Duty to Retreat: There is no formal duty to retreat before using force.
Exclusions: The defense fails if D deliberately provoked the victim, acted out of revenge, or was the initial aggressor without an honest belief in the need for self-defence.

Key Case Law in Self-Defence

R v Palmer [1971]: D stole ganja and was chased by men with sticks/stones. D fired shots, killing one. Ruling: Excessive force in self-defence does not allow for a verdict of manslaughter.
R v Martin (Anthony) [2001]: D shot two burglars at his farmhouse, killing one. D had a personality disorder. The case resulted in manslaughter with diminished responsibility rather than a full self-defence acquittal.
R v Clegg [1995]: A soldier in Northern Ireland fired at a car at a checkpoint. The final bullet was fired as the car drove away. Held: This was excessive and unreasonable force; the murder conviction was upheld.
R v Renouf [1986]: D forced a car off the road after being assaulted by its occupants. The $CA$ held this could be considered force used to assist in a lawful arrest; reasonableness was a matter for the jury.
R v Williams (Gladstone) [1987]: D struck a man he thought was attacking a youth. In reality, the man was arresting the youth for mugging. D's conviction for $ABH$ was quashed because he had a genuine belief a crime was being committed.
Beckford v R [1988]: Reaffirmed that a defendant is entitled to use reasonable force based on the perceived situation.
R v Bird [1985]: D wounded a victim, claiming self-defence. The $CA$ ruled that while demonstrating an unwillingness to fight is good evidence of reasonableness, D does not necessarily have to withdraw or temporize to act lawfully.
Constraint on Statutory Defence: A person cannot rely on the Statutory Defence (prevention of crime) if the perpetrator is below the age of criminal responsibility (doli incapax), insane, or in a state of automatism. In such cases, D must rely on Common Law self-defence.

Self-Defence and the Role of Intoxication

If D pleads self-defence based on a mistake regarding the situation, and that mistake was induced by voluntary intoxication, the defence fails.
R v O’Grady [1987]: D caused serious injuries while intoxicated and claimed self-defence. Ruling: A defendant cannot rely on a mistake of fact induced by voluntary intoxication for the purposes of self-defence.
R v Hatton [2005]: D (a manic-depressive on Lithium) drank excessively and killed a friend with a sledgehammer, mistakenly thinking he was being attacked with a stick. Ruling: A drunken mistake cannot be relied upon for self-defence.
Logical Outcome: An intoxicated D who kills might escape a murder conviction if they lacked $MR$ (reducing it to manslaughter), but they cannot use their intoxicated mistake to ground a self-defence claim.

Special Provisions: Householder Cases

Section 43 of the Crime and Courts Act 2013 (amending s. $76$ CJIA $2008$ ) introduced specific standards for "householder cases."
In these instances, disproportionate force may sometimes be used against an intruder.
The defense is only negated in householder cases if the force used is grossly disproportionate.
