Mens Rea Law Essay Examples

Explain the meaning of the term 'mens rea'.

Mens rea is the mental element of an offence and each offence has its own level of mental element or state of mind.

Grade: A-C | £0.00.

Mens rea is often stated to be the requirement of a 'guilty mind' before any act or actus reus can properly be considered to be criminal. Mens rea is the mental element of an offence and each offence has its own level of mental element or state of mind. The Crown Prosecution Service, on behalf of the state, must prove that the defendant had the necessary mens rea for the offence charged.

In many cases the necessary state of mind that must be established by the prosecution is intention (this is reserved for the most serious crimes) but it is not always required. On some occasions recklessness or negligence may be sufficient.

Whilst mens rea is required in order to establish criminal liability, it is not necessary to prove that the accused had a motive. Motive is the reason for doing something and is not the same. Motive may be useful earlier in an investigation when trying to establish leads and the reason why someone may have wanted to harm or injure someone, but otherwise it is not relevant to the question of whether the accused committed the actus reus or 'guilty act'.

Nor does mens rea necessarily mean that the accused had an intention to commit a criminal act or that the person charged knew that it was unlawful or against the law. Mens rea is about culpability. The criminal law is about prohibiting behaviour which is unacceptable to society as a whole. It is about protecting society and holding to account perpetrators of offences. The criminal law is concerned with ‘blameworthiness’.

Some offences are more serious than others – the more serious the offence the higher the level of mens rea. As a result serious offences carry a higher level of penalty including custodial sentences. It could be argued therefore that a factor in determining whether an offence is serious or not is the level of mens rea.

Intention is reserved for the serious offences i.e. murder, wounding with intent under S18 of the Offences Against the Person Act 1861and robbery.

These levels can be likened to a pyramid. At the top are the serious offences where intention must be proven. Intention is also known as specific intention. In a great many cases the question of whether the defendant intended to bring about a particular consequence will not pose a problem for the jury and the jury will be able to apply common sense to help them answer the question based upon the evidence. It will only be in a few cases that the trial judge will need to advise the jury about the law in this area.

The modern practice is to try and keep any advice straight forward and free from technical language which might unduly complicate matters. Intention has been defined as 'a decision to bring about, in so far as it lies within the accused's power, (the prohibited consequence), no matter whether the accused desired that consequence of his act or not' (Mohan (1976)).

Mohan was the defendant who responded to the police officer's signal to stop by slowing down but then accelerated towards the officer. The officer moved out of the way and Mohan drove off. Mohan was charged with attempt to cause bodily harm by wanton driving at a constable.

Intent is the main element of an attempt and is the only mens rea of attempts. This form of intention is known as direct intent and arises where the defendant is acting to bring about a certain aim or result and intends to achieve this.

A form of intention known as oblique intent or 'foresight of consequences' can be more problematic for the jury. Oblique intent often arises in cases involving consequences which the defendant may argue were not his intention at all. The issue raised then is 'surely the defendant must have realised that the result would arise'. Defining oblique intent has been a challenge for the courts over the years.

Juries are assisted bySection 8 of theCriminal Justice Act 1967but it still leaves open the matter of whether intention can be inferred or found from the evidence. In Moloney (1985), where the defendanthad shot and killed his stepfather as part of a drunken challenge to see who was the quickest to load and fire a shotgun, it was decided that foresight is not the same as intention but it amounts to evidence from which intention can be inferred.

A series of cases followed (Hancock and Shankland (1986) and R v Nedrick (1986) in which the courts sought to refine their approach.

In R v Hancock and Shankland the two defendants dropped lumps of concrete from a bridge into the path of a taxi taking a strike breaker to work during the miners strike of 1984. The driver of the taxi was killed. The defendants said they had only intended to block the road to prevent the taxi taking the miner to work but they were tried and convicted of murder. They appealed and a verdict of manslaughter was substituted. It was reaffirmed that intention to kill or do GBH on the part of the defendant had to be established.

Lord Scarman felt that the Moloney guidelines were defective and may have misled the jury. He was of the opinion that intention was not to be equated with foresight of consequences, but that intention could be established if there was evidence of foresight and the more likely that it was foreseen, the more likely it is that it was intended. In other words foresight was to be regarded as evidence of intention and not as an alternative form of it.


In Nedrick the defendant poured paraffin through the letterbox of a house causing a fire to start and set fire to the house,the house burnt down and one of the children died. He said he had not intended to murder anyone he had only meant to wake up the owner of the house and frighten her, he was convicted of murder.


On appeal the conviction of murder was overturned and a verdict of manslaughter was substituted. Lord Lane said 'Where the charge is murder and in the rare cases where the simple direction is not enough, the jury should be directed that they are not entitled to infer the necessary intention, unless they feel sure that death or serious bodily harm was a virtual certainty (barring some unforeseen intervention) as a result of the defendant's actions and that the defendant appreciated that such was the case.


Where a man realises that it is for all practical purposes inevitable that his actions will result in death or serious harm, the inference may be irresistible that he intended that result, however little he may have desired or wished it to happen. The decision is one for the jury to be reached upon a consideration of all the evidence.'

This series of cases culminated inR v Woollin (1998) in which the former House of Lords ruled that a jury could find intention where they felt sure that the consequence was a virtual certainty and that the defendant appreciated this. The House preferred to use the word 'find' instead of the word 'infer' used in the previous decision of Nedrick.

The case of Woollin concerned the defendant's act of throwing his very young baby towards a pram some three or four feet away. To many this would appear to be deplorable and wrong – to risk harming the baby in this way. The court had to decide whether this 'obvious risk' was enough, bearing in mind the serious consequences, for the accused to receive a conviction for murder, as the baby had hit a wall and suffered head injuries and died. There was no doubting that the defendant was responsible but the question was whether the defendant realised the risk. Towards the end of his summing up the judge directed the jury that if they were satisfied that the appellant "must have realised and appreciated when he threw that child that there was a substantial risk that he would cause serious injury to it, then it would be open to you to find that he intended to cause injury to the child and you should convict him of murder."

In Woollin the House of Lords approved of the direction in Nedrick but disapproved of the two part questions or test. The direction represents a further development of the concept of oblique intent.

On the second level of the pyramid, so to speak, comes recklessness for less serious offences such as manslaughter, rape, some assaults and criminal damage. Recklessness is the taking of an unjustifiable risk. In other words the defendant realises that there is a risk but decides to go ahead anyway. The test is subjective and was laid down in the case of Cunningham (1957) and became known as Cunningham recklessness. The case of Cunningham concerned a defendant who tore a gas meter from the wall of an empty house in order to steal money contained in the meter. Gas escaped and a woman next door was harmed as a result. He was charged with administering a noxious substance. The issue in the case was the meaning of the term 'maliciously' and it was decided that this could include doing something intentionally or being subjectively reckless.

At one time there were two tests for recklessness under the criminal law and the test to be used depended upon the charge. Subjective recklessness was used for offences against the person and the objective test ( in reality partly objective and partly subjective) was used for other offences such as criminal damage.

This led to obvious criticisms concerning the necessity for two tests and the tests were quite technical. If the objective test was used the the test was based upon what a reasonable person would have done in the circumstances.

However the House of Lords took the opportunity in R vG and another (2003) to decide that the correct approach was to use a subjective test in criminal damage cases and the objective test (laid down in Caldwell 1982) is no longer used.


Negligence is below recklessness in the pyramid of levels of mens rea and is reserved for specific offences such as traffic and driving offences. Negligence, put simply, is failing to meet the standards of a reasonable person. There are some situations where the conduct of the accused is so bad that it amounts to gross negligence. Gross negligence can give rise to gross negligence manslaughter.

In Adomako (1994) it was decided that an anaesthetist was so negligent in failing to notice that an oxygen pipe had become disconnected during an eye operation, that he was convicted of gross negligent manslaughter. The conviction was appealed against but the house of Lords upheld the Court of Appeal and followed the law as stated in Bateman (1925).

Finally, at the bottom of the pyramid, are strict liability offences which are largely regulatory in nature. It is commonly said that strict liability offences may be defined as offences which do not require mens rea. To be more accurate they are offences where mens rea need not be proved for any element of the actus reus.

There are very few examples of common law offences which can properly be considered to be strict liability offences. They are extremely rare but public nuisance and criminal libel are two better known examples. Statutory offences are much more common, even so there are a number of presumptions which exist which help the courts decide whether the offence in question is a strict liability offence.

There is, for example, a presumption that mens rea is required in order for a person to be convicted of a criminal offence. Most law students will remember the case of Sweet v Parsley (1970) which concerned the question of whether mere knowledge could lead to criminal liability involving premises used for the taking of prohibited drugs. The courts decided that in view of the serious consequences for the individual if convicted and the fact that the offence was criminal in nature, mens rea was required for the offence.

It can be seen the concept of mens rea may be different depending upon the nature of the offence. It covers several levels of culpability depending upon the seriousness of the offence and these have been likened to the levels of a pyramid. The more serious levels, such as intention, being reserved for serious offences such as murder where, because of the gravity of the consequences i.e. life imprisonment for murder, the level of mens rea needed to be proved is higher. With manslaughter the consequence, that is the death of the victim, may be the same, but the mens rea may be lower and only require recklessness or negligence.

Law school is… different, and so is the approach to answering problem based questions. The IRAC method will help you structure your exams and essays, so forget everything you currently know about answering questions and take a read!

What does IRAC mean?

  • Issue: identify the issue.
  • Rule: state the rule/law.
  • Analysis: discuss the law in respect to the facts.
  • Conclusion: provide your conclusion.


Don’t be deceived – it’s harder than it looks

It looks pretty simple, right? Don’t get me wrong, the idea behind IRAC is as simple as things can get – the difficulty is in the execution.

An easy way to explain IRAC is to talk about the things that are most likely to trip you up when using it.

Don’t write an introduction

We are taught during high school and most university courses to rehash the facts or situation as part of an introduction for any answer we give.

At law school, a problem based question simply doesn’t need one. Instead, just write down the issue as a question or a statement. For example: “the issue in this situation is whether plaintiff’s title to the property is indefeasible.” That’s it – now move on to the rule section.

I remember writing a short introduction in a problem based assignment (which I thought was different to an exam, for some unknown reason) even when the lecturer told us not to! In my defence it was early on in my first year (fine – second half of my first year).

A problem that many law students face is failing to adapt to the academic environment of law school. It takes time to reverse old habits and realise that an introduction is no longer necessary.

Don’t pad your answer

Answers in law school should be concise and relevant – the IRAC method will assist, but you still need to consider everything you write down and query whether its relevant. Fluff and padding will not help your marks and will not make up for the fact that you don’t know what you’re talking about. Save the extra words for those 7,500 and 10,000 word essays!

Being concise is particularly important in exams when you have time limits to separate students into into credit, distinction and high distinction categories. Expressed bluntly, you can’t bullshit your way through a legal question.

This is enforced by lecturers by imposing low word limits. A 3,000 word assignment might sound like a lot before you start but most people will find themselves at the end scrambling to delete words.

Word limits are also used to identify students who understand the most important concepts and reward them for it. You will always get the most marks if you:

  • can identify the key issues (relevance); and
  • are able to thoroughly consider the issues for each (being concise).

This might mean you need remove any discussion of minor ancillary issues, even if what you wrote is correct.

For example, a 30 mark essay capped at 1500 words might in fact have 40 marks available, depending on what your response is. This generally gives the lecturers some scope when marking papers. However, you would need to write far more than 1500 words to discuss all the issues to get all those marks, which is obviously not allowed.

Write on point and with precision and you will increase your chances to score full marks.

Don’t revisit your answer in your conclusion

Don’t rewrite your answer in your conclusion section. Your conclusion is essentially a “yes” or “no” response to the issue (eg “the plaintiff’s title to the property is not indefeasible”). Similar to the issue section, limit it to one sentence and spend your effort on the far more important analysis section – this is where all the marks lie.

Be flexible with the rule and analysis sections, and structure your answer to help the reader

The ideal question to answer is one where the various issues you need to discus and explain are entirely separate from one another and your structure is literally: issue; rule; analysis; and conclusion (perhaps repeated three or four times). You might get a few of these in an exam, but unfortunately, they are not in abundance!

Most questions, will have overlapping issues and this is where structure becomes very important. For written essays and assignments you will have time to plan this out properly. In exams, it will come down to practice, so make sure you run through as many practice exams as you can to find out the best structure for any particular question (exam topics are frequently repeated so you can figure out what will be on your exam early).

The IRAC method is not for all types of questions

You might have already picked it up, but the IRAC method works best with problem based questions. If you’ve got a “discuss the the advantages and disadvantages of indefeasibility in property law” kind of question, then first of all I feel genuinely sorry for you, and secondly, you will need to find another way to answer this question.

IRAC answer examples

It’s easier to explain this method if by looking at an example IRAC answer. The below examples are very brief and don’t go into much caselaw detail, but they should suffice for a general example.

I have chosen the first one from criminal law because this is usually taught early on in most degrees. The second is in a different post on exam scripts, and is from a key area in contract law.

The words in [square brackets] or in italics are to indicate [structure] or are just general commentary and would not be included in your answer.

Criminal law IRAC example – Murder/manslaughter

[Exam heading] Murder

[Exam heading] Issue

  • Did D commit murder?
  • Can prosecution charge D with murder?

[Exam heading] Law and Analysis

  • [Exam heading] (a) Mens Rea
    • (State the law)
    • (This is the analysis) In this situation,  [there is insufficient evidence of intention]
  • [Exam heading] (b) Actus reus
    • (State the law)
    • (This is the analysis) Here, it is clear that D’s actions were voluntary, and that the act caused the death of V.
    • (Still the analysis) It could be argued that [act] was actually [something else], and therefore should not be considered voluntary. This was argued in [key case], however here, [the other important factor in key case] was not present, which means that any argument from D that actus reus is not made out is unlikely.
    • (I can’t remember much of crim, but usually an exam question will have a factual scenario that plays on the facts of a key case. For example, in this question there might be something in the facts which requires you to discuss how the “voluntary” act is similar or different to a voluntary act in the key case. Refer to it and make a conclusion. If the chief examiner is particularly cruel, they will blend a factual scenario from two key cases, and you will need to refer to both and make a call on what is more applicable.)

[Exam heading] Conclusion

  • D unlikely to be charged with murder. While there is sufficient evidence for actus reus, there is no mens rea.

(You will now want to determine whether D can be charged with a lesser office based on a different mens rea. To make the best use of time, refer back to what you have already written in the murder section.

Just as a warning – only refer back to things in the same answer. Sometimes, different questions in an exam booklet will be marked by different people. They might not have time to skip back to a different question to find something you have written.)

[Exam heading] MANSLAUGHTER

[Exam heading] Issue

  • Can D be charged with manslaughter?

[Exam heading] Law and Analysis

  • [Exam heading] (a) Mens rea
    • The mens rea for manslaughter is… (as I said above, it’s been a looooong time since I studied criminal law. I have no idea what elements should go here. Recklessness?? Also, surely law students learn that this is the “fault element” now?)
    • In this situation… (apply facts)
  • [Exam heading] (b) Actus reus
    • The elements for manslaughter are the same as for murder. These have been discussed above and are present in this situation.

[Exam heading] Conclusion

  • D is likely to be charged with manslaughter as fault and external elements are all present.

(Part of your job is to make life easy for the marker. That’s the great thing about IRAC – it provides an ideal structure to frame your answer around. However, when you don’t need to write much then the structure can feel very forced. If you think your answer is going to look a bit stupid, just put everything in the one paragraph, but make sure you stick to the IRAC structure. See the below paragraph for an example.)

[Alternative manslaughter IRAC section]

(Issue) As murder is unlikely to be found, an alternative charge of manslaughter should be considered. (The following is law and analysis for actus reus) The actus reas for manslaughter is identical to murder, and is therefore present, as discussed above. (Next up, law and analysis for mens rea) However, the mens rea is different. The mens rea for manslaughter is…. [state law, discuss]. (Conclusion) Therefore, it is likely/unlikely that D will be charged with manslaughter.

Contract law IRAC example – termination of contracts

In my post on exam scripts you will find an IRAC example for termination of contracts. It’s from one of my old exam scripts and is a little more detailed than the above example for criminal law.
