What is Concurrence in law?

Concurrence in criminal law refers to the requirement that the defendant's culpable mental state (mens rea) must coincide with the actus reus at the same time during the commission of a crime.

Detailed Explanation

Concurrence is a fundamental principle in criminal law that ensures that a criminal act (actus reus) and the mental state (mens rea) required for a crime occur simultaneously. This principle serves to establish a direct link between the offender's intentions and their actions, ensuring accountability. For example, if an individual accidentally causes harm without the intent to do so, this lack of mens rea means that the requirement for concurrence is not satisfied, potentially absolving them from criminal liability.

The necessity of concurrence serves as a safeguard against punishing individuals simply for their thoughts or intentions without any corresponding action. Criminal statutes typically require both a prohibited act and a guilty mind for a conviction to proceed, which reinforces the idea that liability should be based on both conduct and state of mind.

To illustrate, consider a case where Person A intends to commit robbery (mens rea) but mistakenly breaks into the wrong house and steals items that do not belong to the intended victim. In this scenario, while Person A’s intention was to commit a crime, the act of stealing from an unintentional target may raise questions about the validity of concurrence, depending on the specific state’s laws regarding mens rea and actus reus.

Issues surrounding concurrence can become complex in multifaceted crimes, particularly in cases involving negligence or recklessness, where defining the exact moment and nature of the mental state in relation to the act can be challenging. Courts often have to dissect the sequence of events to determine whether the requisite concurrence was indeed present at the time of the crime.

Historical Origin

The concept of concurrence has its roots in early common law principles which emphasized the necessity for a link between intent and conduct in determining criminal liability.

  2. 2Mens Rea (guilty mind)
Key Cases

R v. Cunningham

1957

This case established the principle that mens rea requires intent to cause harm, demonstrating the importance of concurrence.

R v. Miller

1983

This case highlighted the necessity of men's rea in conjunction with actus reus in the context of negligence.

State v. Smith

1988

This case reinforced the concept that even if a person intends to commit a crime, absence of actus reus negates liability.

Hypothetical

Defendant B plans to poison a rival but accidentally spills the poison on their own food instead and consumes it. Here, B had the intent (mens rea) to commit a crime but the act (actus reus) did not occur as intended, illustrating the concept of concurrence.

Common Confusions

Confusion: Students often confuse the sequence of actus reus and mens rea, thinking one must come before the other in time.

Clarification: In fact, both must coexist at the time of the defendant’s action.

Confusion: Some believe that a negligent act can substitute for mens rea to establish concurrence.

Clarification: Negligence often does not satisfy the mens rea requirement for most crimes, as it implies a failure to be aware rather than a deliberate intention.

Exam Tip

Focus on clearly defining both actus reus and mens rea in hypothetical scenarios, and be prepared to analyze whether they coincide to establish liability.
