Corpus delicti

In Western law, corpus delicti (Latin for 'body of the crime'; pl. corpora delicti), is the principle that a crime must be proven to have occurred before a person could be convicted of having committed that crime. For example, a person cannot be tried for larceny unless it can be proven that property has been stolen. Likewise in order for a person to be tried for arson, it must be proven that a criminal act resulted in the burning of a property. Black's Law Dictionary (6th ed.) defines "corpus delicti" as: "the fact of a crime having been actually committed". In common law systems, the concept has its outgrowth in several principles. Many jurisdictions hold as a legal rule that a defendant's out-of-court confession alone, is insufficient evidence to prove the defendant's guilt beyond reasonable doubt. A corollary to this rule is that an accused cannot be convicted solely upon the testimony of an accomplice. Some jurisdictions also hold that without first showing independent corroboration that a crime has occurred, the prosecution may not introduce evidence of the defendant's statement.
