Which term refers to the guilty act in a crime?

The term that refers to the guilty act in a crime is actus reus. This concept is fundamental in criminal law as it encompasses the physical act or conduct that constitutes a criminal offense. In order for an individual to be found guilty of a crime, there must typically be a demonstration of this guilty act, aligned with the principles of law.

Actus reus can include a wide range of behaviors, from a physical action (such as theft or assault) to failure to act in certain circumstances where a legal duty is imposed (such as in cases of neglect). This term highlights the necessity of a tangible action or omission that leads to criminal liability.

The other terms, while related to the legal framework of criminal justice, do not specifically denote the guilty act. Mens rea, for instance, refers to the mental state or intent of the person committing the crime, which is essential for differentiating between various levels of culpability. Due process pertains to the legal procedures that must be followed to ensure fair treatment under the law, and criminal intent relates to the intention behind a person's actions when committing a crime. Thus, actus reus is the correct term that specifically identifies the conduct involved in committing a crime.
