Which term describes a body of evidence necessary to prove a crime has occurred?

The term that describes a body of evidence necessary to prove that a crime has occurred is "corpus delicti." This Latin phrase translates to "body of the crime" and refers to the essential facts that must be established to demonstrate that a crime has taken place. It requires that there be evidence of both the occurrence of the criminal act and the existence of a criminal law violation. For example, in a homicide case, the corpus delicti would include evidence that a person has died and that it was due to criminal action, demonstrating that a crime is established beyond mere suspicion.

The other terms, while relevant in legal discussions, do not pertain specifically to the concept of proving that a crime occurred in the same way. A jurat refers to an affidavit or sworn statement, prima facie indicates that there is sufficient evidence to support a case unless disproven, and quid pro quo relates to a mutual exchange or barter rather than the evidence required to prove a crime.
