Learning Outcomes
This article explains the concept of mens rea (the mental element) in criminal law. It details the different states of mind required for criminal liability, such as intention (direct and indirect/oblique) and recklessness. It also briefly touches upon negligence and strict liability. Understanding these principles is essential for analysing criminal scenarios and identifying the correct offence. This knowledge will enable you to apply the relevant rules to SQE1-style multiple-choice questions concerning criminal liability.
In addition, the article clarifies how juries determine intention and foresight under the Criminal Justice Act 1967, s 8, and shows how the courts treat “maliciously” in offences under the Offences Against the Person Act 1861 (as intention or recklessness). It also explains the interaction between mens rea, transferred malice, and the requirement for coincidence (contemporaneity) of actus reus and mens rea, and highlights the classification of offences into basic intent, specific intent, and ulterior intent for key doctrines such as intoxication.
SQE1 Syllabus
For SQE1, you are required to understand the different mental states that constitute mens rea and how they apply to various offences; you will need to differentiate between intention (direct and indirect) and recklessness, recognise situations involving negligence or strict liability, and appreciate transferred malice and the requirement for coincidence of actus reus and mens rea. Your understanding will be tested through scenario-based questions requiring application of these principles, with a focus on the following syllabus points:
- the meaning of direct intention (aim or purpose)
- the test for indirect (oblique) intention (foresight of virtual certainty)
- the subjective test for recklessness (foresight of risk and unreasonable to take it)
- the distinction between specific and basic intent offences in the context of mens rea
- the principle of transferred malice and its limitations
- the requirement for coincidence of actus reus and mens rea
- the s 8 Criminal Justice Act 1967 approach to drawing inferences of intention or foresight from all the evidence
- how “maliciously” in OAPA 1861 is satisfied by intention or recklessness
- the presumption of mens rea and how courts identify strict liability where statutes are silent.

Introduction
For most criminal offences, the prosecution must prove not only that the defendant (D) committed the prohibited act or caused the prohibited result (actus reus), but also that D possessed a particular state of mind at the time – the mens rea, or ‘guilty mind’. The mens rea required varies depending on the specific offence. Understanding the different types of mens rea is fundamental for determining criminal liability. This article explores the core concepts of intention, recklessness, negligence, strict liability, transferred malice, and the principle of coincidence.
Key Term: Mens Rea
The mental element required for a particular crime. It refers to the state of mind of the defendant at the time of the actus reus, such as intention or recklessness.
Two overarching ideas run through this topic:
- Mens rea is specific to each offence. It is never just “intention” or “recklessness” in the abstract; it is intention or recklessness as to a particular element of the offence (for example, intention to kill for murder, or recklessness as to damage for criminal damage).
- Mens rea is usually assessed subjectively. Juries decide what D actually intended or foresaw by drawing inferences from all the evidence (Criminal Justice Act 1967, s 8). Objective evaluation appears in limited contexts (e.g., negligence, or the “unreasonable to take the risk” limb of recklessness).
Finally, the law recognises a spectrum of culpability. Intention represents the highest level of blameworthiness; recklessness reflects conscious risk-taking; negligence relies on falling below the standard of the reasonable person. Some statutory schemes displace mens rea altogether for specific elements: strict liability.
Intention
Intention represents the highest level of culpability and is the required mens rea for the most serious offences, such as murder. It can be divided into two forms: direct intention and indirect (or oblique) intention.
Direct Intention
This is the most straightforward form of intention. It refers to the situation where the consequence is the defendant’s aim or purpose. If D acts with the specific objective of bringing about the prohibited result, they have direct intention. Motive (the reason behind the action) is generally irrelevant to whether direct intention exists. A person may intend a result they regret or deplore; motive may help a jury understand why D acted but does not change what D intended.
Key Term: Direct Intention
Where the consequence is the defendant's aim, purpose, or desire.
Jurors are not usually given a technical definition: “intention” is a common word and carries its ordinary meaning. Only where intention is disputed or where the case involves foresight of consequences that were not D’s aim will the judge need to give further guidance about indirect (oblique) intention.
Worked Example 1.1
Ahmed wants to damage his neighbour’s prize-winning roses because he is jealous. He waits until nightfall, goes into his neighbour’s garden, and deliberately cuts the heads off all the roses with secateurs. Does Ahmed have direct intention to cause criminal damage?
Answer:
Yes. Ahmed’s aim and purpose was to damage the roses. He deliberately acted to achieve that consequence. Therefore, he possesses direct intention for the mens rea of criminal damage.
Indirect (Oblique) Intention
Sometimes a defendant may argue that the prohibited consequence was not their primary aim, but merely an unintended side-effect of achieving another goal. In such cases, the jury may still find intention if the test for indirect (or oblique) intention is met.
The leading case is R v Woollin [1999] AC 82. The House of Lords established a two-part test. The jury should be directed that they are not entitled to find the necessary intention unless they feel sure that:
- The result (e.g., death or serious bodily harm) was a virtually certain consequence of the defendant's actions; and
- The defendant realised that the result was a virtually certain consequence of their actions.
If the jury finds both parts are satisfied, they may (but are not required to) find that the defendant intended the result. Foresight of virtual certainty is therefore a powerful piece of evidence from which a jury can infer intention, not a legal equivalence with intention.
Key Term: Indirect (Oblique) Intention
Where the result was not the defendant's primary purpose but was a virtually certain consequence of their actions, and the defendant realised this.
Two guardrails are worth emphasising:
- Oblique intention is only relevant where the offence genuinely requires intention as to a consequence and where that consequence was not D’s aim. If the required mens rea can also be recklessness as to that consequence, then the proper question is usually whether D foresaw a risk (recklessness), rather than whether D foresaw virtual certainty (oblique intention).
- The threshold is high. “Possible,” “likely,” or even “highly probable” consequences are not sufficient; only “virtually certain” will do.
Worked Example 1.2
Ben places a bomb on a cargo aeroplane, timed to explode mid-flight over the sea, with the aim of destroying the cargo for an insurance claim. Ben knows the pilot will inevitably be killed when the bomb explodes, but killing the pilot is not his aim. The bomb explodes, killing the pilot. Does Ben have the mens rea for murder?
Answer:
Ben has direct intention to destroy the cargo (criminal damage). He does not have direct intention to kill the pilot. However, the pilot's death was a virtually certain consequence of the bomb exploding mid-flight. If Ben realised this virtual certainty, the jury may find he had indirect intention to kill, satisfying the mens rea for murder.
Exam Warning
Remember that foresight of virtual certainty is evidence from which a jury may infer intention; it is not intention itself. An SQE question might incorrectly suggest that foresight of virtual certainty automatically equals intention. This is legally incorrect according to Woollin.
Further practical points about intention:
- Jurors must not be directed that they are bound to find intention; they remain the arbiters of fact, drawing inferences under s 8 Criminal Justice Act 1967 from all the evidence.
- Oblique intention is typically litigated in homicide where “intention to kill or cause grievous bodily harm” is the standard. For other offences that require intention to bring about a result, the same Woollin principles guide the jury in rare, borderline cases.
Recklessness
For many offences, it is sufficient for the prosecution to prove that the defendant was reckless, which represents a lower level of culpability than intention. The legal test for recklessness is subjective.
Subjective Recklessness (Cunningham / R v G)
The current test for recklessness was established in R v G and Another [2003] UKHL 50, which overruled the previous objective test from MPC v Caldwell and effectively confirmed the earlier subjective test from R v Cunningham [1957] 2 QB 396.
A defendant acts recklessly with respect to:
- A circumstance – when they are aware of a risk that it exists or will exist; or
- A result – when they are aware of a risk that it will occur;
and - In the circumstances known to them, it was unreasonable to take that risk.
The key element is the defendant's subjective awareness of the risk. It does not matter if the risk would have been obvious to a reasonable person if the defendant genuinely did not foresee it (perhaps due to age or a particular mental state). However, whether it was unreasonable to take the risk is judged largely by an objective yardstick, evaluated against the circumstances as D knew or believed them to be. Everyday activities can involve risk; the question is whether, viewed in context, D’s decision to run the risk was unjustifiable.
Key Term: Recklessness (Subjective)
Where the defendant foresees a risk of the prohibited consequence occurring (or circumstance existing) and unreasonably goes on to take that risk.
Practical consequences of R v G:
- A child or a vulnerable adult who did not, in fact, appreciate a risk cannot be reckless, even if a reasonable adult would have.
- The magnitude of the risk does not have to be high; awareness of any non-trivial risk may suffice. The greater the risk, the easier it will be to find that taking it was unreasonable.
“Maliciously” in OAPA 1861 offences is satisfied by intention or recklessness in the Cunningham sense. Thus, for s 20 (unlawful wounding/GBH), liability attaches where D intended or was reckless as to causing some harm; D need not foresee serious harm.
Worked Example 1.3
Chloe throws a heavy stone off a bridge onto a motorway below, aiming to hit a road sign. She doesn't intend to hit any cars, but she is aware there is a risk that she might. The stone hits a car, smashing the windscreen. Is Chloe reckless as to causing criminal damage?
Answer:
Yes. Chloe was subjectively aware of the risk that throwing the stone might cause damage to a vehicle. It was objectively unreasonable for her to take that risk (as there is no social utility in throwing stones at motorways). Therefore, she possesses the mens rea of recklessness required for criminal damage.
A common pitfall is to conflate what D foresaw (subjective) with what they ought to have foreseen (objective). “Ought to have foreseen” is not the test for recklessness (save where a statute expressly provides otherwise). The correct focus is what D actually appreciated at the time.
A further but related issue is classification:
- Basic intent offences are those that can be committed intentionally or recklessly (e.g., criminal damage, s 20 OAPA, assault and battery).
- Specific intent offences are those where only intention will suffice (e.g., murder, theft, robbery, s 18 OAPA, attempted crimes).
- Ulterior intent offences require proof of an “extra” mental element beyond the actus reus (e.g., aggravated criminal damage requires intention or recklessness as to endangering life by the damage; burglary s 9(1)(a) requires entry as a trespasser with intent to steal, inflict GBH, or cause criminal damage).
This classification matters for doctrines such as intoxication and attempts.
Negligence
Negligence generally plays a limited role in defining mens rea for criminal offences, though it is relevant for some, such as gross negligence manslaughter (see separate materials). It involves falling below the standard of care expected of a reasonable person in the same situation. Unlike recklessness, it does not require the defendant to have foreseen any risk; the focus is on what the reasonable person would have foreseen or done.
Negligence is thus “inadvertent” fault, whereas recklessness is “advertent” risk-taking. Because negligence can criminalise blameless mistakes, it is typically confined to regulatory or driving offences and the special context of gross negligence manslaughter.
Worked Example 1.4
During a community bonfire, Priya stacks dry wood too close to a boundary fence. She fails to check wind conditions before lighting it. Embers drift and scorch the neighbour’s garden furniture. She did not turn her mind to any risk. Is Priya reckless or negligent?
Answer:
On these facts, Priya did not actually foresee a risk; she failed to think about it. This points away from recklessness (which requires subjective foresight) and towards negligence. Whether she is criminally liable depends on the offence charged: many damage offences require intention or recklessness and would not be made out by mere negligence, but regulatory offences might be.
Strict Liability
Some offences, known as strict liability offences, do not require any mens rea at all regarding one or more elements of the actus reus. Liability is imposed simply upon proof that the defendant committed the prohibited act. These are often regulatory offences (e.g., certain road traffic offences like driving over the prescribed alcohol limit, or licensing and environmental controls). The justification is usually public protection and ease of enforcement.
The starting point remains a strong presumption that mens rea is required. Where a statute is silent, courts examine its purpose and context. Key features often considered include whether the offence is “truly criminal,” whether it concerns public safety, and whether strict liability would be effective to secure compliance.
Defences based on mistake are generally unavailable for strict liability elements, although in some statutory schemes honest mistake about consent can operate as a lawful excuse (e.g., s 5(2)(a) Criminal Damage Act 1971). Where a statute is silent on mens rea, courts can and do read in a fault element unless strict liability is clearly or by necessary implication intended.
Worked Example 1.5
A shopkeeper sells an age-restricted product believing, on an honest but careless glance at a forged ID, that the customer is old enough. The statute imposes liability on proof of sale to a person under the age without any express mental element for that fact. Is the shopkeeper liable?
Answer:
If the statute creates strict liability for the age element, the shopkeeper’s honest mistake will not excuse the sale unless the statutory scheme provides a due diligence defence. Where Parliament has imposed strict liability to protect the public (e.g., children), the court will ordinarily give effect to that, subject to any express statutory defences.
Transferred Malice
Sometimes a defendant aims to commit a crime against one target (person or property) but, by mistake, harms another target instead. The doctrine of transferred malice allows the defendant's mens rea (the 'malice') intended for the original target to be transferred to the actual victim or property harmed.
Key Term: Transferred Malice
A legal doctrine where the mens rea directed towards one person or object can be transferred to the actual person or object harmed, provided the actus reus committed is the same type of crime as that intended.
In R v Latimer (1886) 17 QBD 359, D aimed a blow with a belt at one person in a pub but accidentally struck another person (V). His intention to strike the first person was transferred to V, making him liable for the battery against V.
However, the doctrine has limits. Malice cannot be transferred between different types of offences. In R v Pembliton (1874) LR 2 CCR 119, D threw a stone intending to hit people but missed and broke a window. His intention to cause harm to people could not be transferred to the property damage, so he was not guilty of criminal damage based on transferred malice (though he might have been reckless).
Thus, transfer works “person-to-person” or “property-to-property” when the offence type matches, but not “person-to-property” or vice versa. Nor is there any “double transfer” or generalised transfer (e.g., through an intermediate non-personal target). Where mens rea includes recklessness, the doctrine is often unnecessary because D may be reckless as to the harm that in fact occurred.
Worked Example 1.6
Lena fires a shot at X intending to cause GBH, but misses and shatters a nearby café window. Can her intent transfer to criminal damage?
Answer:
No. The intended offence (against the person) and the offence committed (criminal damage) are different. Transferred malice does not apply across different offence types. However, if Lena foresaw a risk that property might be damaged and unreasonably took that risk, she could be liable for criminal damage on a recklessness basis.
An additional point arises where the intended victim is A and the act injures B who is an unintended victim, and where both completed and inchoate liability might follow. D may be guilty of the completed offence against B and, simultaneously, attempt against A (e.g., attempt to murder A while actually murdering B). But where a foetus later born alive dies from injuries inflicted in utero, the courts have declined to apply transferred malice to create murder via a “double transfer” (see Attorney General’s Reference (No 3 of 1994)).
Coincidence of Actus Reus and Mens Rea (Contemporaneity)
A fundamental principle is that the actus reus and mens rea must coincide in time. The defendant must possess the required guilty mind at the precise moment they commit the guilty act.
However, the courts have developed ways to establish coincidence even when the actus reus and mens rea do not perfectly align chronologically:
-
Continuing Act: If the actus reus can be regarded as a continuing act, it is sufficient if the defendant forms the mens rea at some point while the act is ongoing. In Fagan v MPC [1969] 1 QB 439, D accidentally drove onto a police officer's foot (no mens rea at this point) but then deliberately refused to move the car (mens rea formed). The court held the driving onto the foot and remaining there was a continuing act, and liability for battery arose when the mens rea was formed during that continuing act.
-
Single Transaction: A series of acts may be treated by the court as part of a single transaction. If the defendant has the required mens rea at some point during that transaction, even if not at the exact moment the actus reus is completed, coincidence can be established. In Thabo Meli v R [1954] 1 WLR 228, the defendants attacked V intending to kill him. Believing him dead, they rolled his body off a cliff to fake an accident. V survived the initial attack but died of exposure later. The Privy Council held that the attack and disposal of the body were part of one transaction, and the initial intention to kill covered the entire sequence of events, leading to a murder conviction.
In omissions cases, where D creates a dangerous situation, mens rea can coincide with the actus reus by regarding the failure to act as part of an ongoing actus reus. In R v Miller [1983] 2 AC 161, D accidentally started a fire in a house but did nothing to extinguish it or call for help. His failure to act after becoming aware of the danger was enough when coupled with the earlier creation of the risk.
Key Term: Contemporaneity (Coincidence)
The principle that the actus reus (guilty act) and mens rea (guilty mind) must occur at the same time for criminal liability to be established.
Worked Example 1.7
Nadia reverses and unknowingly traps a cyclist’s foot under her car tyre. Moments later she learns what she has done. Annoyed about being late, she decides to wait several minutes before moving the car. Is there coincidence of mens rea and actus reus for battery?
Answer:
Yes. Initially there was no mens rea. Once Nadia realised and chose to remain, the application of force became a continuing act to which her mens rea attached (as in Fagan). Coincidence is established during the continuing application of force.
Additional practical points on contemporaneity
- The continuing act and single transaction devices ensure that culpable conduct is not immunised by artificial fragmentation of events.
- The devices do not dispense with proof of mens rea; rather, they recognise that the culpable mental state can be “joined” in time with conduct when the conduct is continuing or forms part of one composite sequence.
Additional applied issues and links
Although not separate headings in this article, two recurring ideas help situate mens rea in problem questions.
- The s 8 Criminal Justice Act 1967 direction: juries must not be told to presume that D intended or foresaw the natural consequences of their acts. Instead, they should decide intention or foresight by reference to all the evidence, drawing such inferences as appear proper.
- The impact of intoxication: for specific intent offences, voluntary intoxication may prevent the formation of the required intention; for basic intent offences, voluntary intoxication is not a defence because recklessness as to becoming intoxicated substitutes for the required mens rea. This explains why classifying an offence as specific or basic intent is critical.
Key Point Checklist
This article has covered the following key knowledge points:
- Mens rea refers to the mental element required for a crime.
- Direct intention is the defendant's aim or purpose.
- Indirect (oblique) intention involves foresight of a virtually certain consequence (R v Woollin).
- Recklessness requires subjective foresight of an unjustified risk (R v G).
- “Maliciously” in the OAPA 1861 is satisfied by intention or recklessness.
- Negligence involves falling below the standard of a reasonable person and is distinct from advertent risk-taking.
- Strict liability offences require no mens rea for at least one element of the actus reus; the presumption of mens rea can be displaced in limited contexts.
- Transferred malice allows mens rea to be transferred between similar offences but not different types of offences, and no “double transfer.”
- The actus reus and mens rea must generally coincide in time (contemporaneity), but the continuing act and single transaction doctrines can establish coincidence where they do not perfectly align.
- Classification matters: basic intent (intent or recklessness), specific intent (intent only), and ulterior intent (extra mental element) influence analysis, especially for intoxication and attempts.
