What is Mens Rea and Actus Reus

Does every wrong in the society come under the definition of Crime? The answer is no. Not every wrong is a crime. To prove a crime, there are so many things that need to be considered.  One of the most important things is Actus Reus and Mens Rea. Actus Reus means guilty action and Mens Rea means guilty intention. If a person does something wrong in society or does something of criminal nature, a lawyer needs to prove that person’s Actus Reus and Mens Rea in court. If any of these two things are missing then that person won’t be considered guilty. It is not always the same. There are few exceptions to this but in maximum cases, both of these two things need to be proved.  In this blog, we will talk about Actus Reus and Mens Rea.

Actus Reus and Mens Rea

Both the term is very old and is based on the Latin Maxim, “actus non facit reum nisi mens sit reawhich means an act does not make the actor guilty unless his mind is guilty too.

In short, actus reus means guilty action and mens rea means guilty intention. To understand these two terms properly, let’s see an example:

Suppose, a woman was beating a man with a broom. Due to grievous hurt, that man died. In this case, the court will see two scenarios. First, whether that woman had any guilty intention and whether the action was wrong or not. Now, hitting with a broom is of course wrong and death due to beating is wrong as well. So, here we can say that Actus Reus is present.

But to understand this scenario clearly, let’s assume that man was abducting a child. To save that child, that woman beat that man. Here, that woman didn’t have any bad intention. In this case, the act done by the woman won’t be called as Crime, or that woman won’t be called a criminal.

So, in order to call a person criminal or to call an activity as crime, the first thing to look upon is whether the act done by that particular person is wrong and second, with full intention the act was done.

Here is an in depth analysis of the two term

Mens Rea

  1. Definition:
    • Latin for “guilty mind,” it refers to the mental state or intention of the accused at the time the crime was committed.
  2. Focus:
    • Centrally focuses on the defendant’s state of mind, emphasizing the mental element of criminal liability.
  3. Categories:
    • Includes intention (purpose), knowledge (knowing), recklessness, and negligence. Different crimes may require different levels of mental culpability.
  4. Subjectivity:
    • Involves a subjective analysis of the accused’s mental state at the time of the offense.
  5. Voluntariness:
    • Pertains to the intentional mindset of the accused. It is about what the accused knew or intended when committing the crime.
  6. Flexibility:
    • Allows for flexibility in assessing culpability based on the accused’s mental state.

Actus Reus:

  1. Definition:
    • Latin for “guilty act,” it refers to the physical act or conduct that constitutes a criminal offense.
  2. Focus:
    • Focuses on the observable, external actions that constitute the prohibited act.
  3. Voluntariness:
    • Requires a voluntary, willed action. Involuntary actions or those performed under duress may not constitute criminal liability.
  4. Causation:
    • Requires a causal relationship between the defendant’s actions and the prohibited consequence.
  5. External Element:
    • Is an external, concrete element that can be proven through evidence. It is the physical manifestation of criminal behavior.
  6. Flexibility:
    • Is less flexible and more objectively determined. It is concerned with the tangible, observable actions of the accused.

If Mens Rea is Present and Actus Reus is Absent, Will that be called as Crime?

If only mens rea is present and actus reus is absent then it won’t be called as a crime. Action is very important to be called as crime. Until and unless there is any guilty action, there won’t be any crime.

Mens Rea when not required

As we already said, there exception to the general rule. Here are the cases, where mens rea in not required

  1. Ignorance of Law: Ignorance of law is no excuse. It won’t a defense that a person didn’t know about a law and that’s why he did it.
  2. Public Nuisance: Public nuisance is another ground where mens rea is not required.
  3. Public Interest: Cases which are not criminal in nature but are prohibited in the interest of public at large. For example: Company and consumer relation. A company’s intention is not to provide bad service to consumer but to good services. Where a company supplies defective pieces then it is company’s liability.
  4. Strict Liability Offence: In case of strict liability, mens rea won’t be required as it was established in the case Rylands vs Fletcher (1868)

Relationship Between Mens Rea and Actus Reus:

  1. Criminal Liability:
    • Both mens rea and actus reus are essential components for establishing criminal liability. A crime typically requires the presence of both elements.
  2. Concurrence:
    • There must be concurrence between the accused’s mental state (mens rea) and the physical act (actus reus) for a crime to occur.
  3. Exception:
    • Some offenses, such as strict liability crimes, may not require proof of mens rea. Here, the focus is solely on the prohibited act, and the defendant’s mental state is not a relevant factor.
  4. Degrees of Culpability:
    • The combination of mens rea and actus reus allows the legal system to differentiate between degrees of culpability, providing a nuanced approach to criminal responsibility.

In conclusion, mens rea and actus reus work together to establish criminal liability, recognizing that both the mental state of the accused and the physical act are integral to the commission of a crime. While mens rea delves into the realm of intention and mindset, actus reus focuses on the observable, external actions that constitute a criminal offense. The interaction between these two elements forms the basis of a comprehensive framework for evaluating criminal responsibility.
