Inchoate offence

An inchoate offense, preliminary crime, or inchoate crime is a crime of preparing for or seeking to commit another crime. The most common example of an inchoate offense is "attempt". "Inchoate offense" has been defined as: "Conduct deemed criminal without actual harm being done, provided that the harm that would have occurred is one the law tries to prevent."

Every inchoate crime or offense must have the mens rea of intent or of recklessness, but most typically intent. Absent a specific law, an inchoate offense requires that the defendant have the specific intent to commit the underlying crime. For example, for a defendant to be guilty of the inchoate crime of solicitation of murder, he or she must have intended for a person to die.

Attempt, conspiracy, and solicitation all require mens rea.

On the other hand, RICO merely requires "knowing", that is, recklessness. Facilitation also requires "believing", yet another way of saying reckless.

Intent may be distinguished from recklessness and criminal negligence as a higher mens rea.

Specific intent may be inferred from circumstances. It may be proven by the doctrine of "dangerous proximity", while the Model Penal Code requires a "substantial step in a course of conduct".

The doctrine of merger has been abandoned in many jurisdictions in cases involving a conspiracy, allowing an accused to be convicted of both conspiracy and the principal offense. However, an accused cannot be convicted of either attempt or solicitation and the principal offense.

A number of defences are possible to the charge of an inchoate offense, depending on the jurisdiction and the nature of the offense.

Impossibility is no defence to the crime of attempt where the conditions creating the impossibility are unknown to the actor.

Originally at common law, impossibility was a complete defence; as it was under French law at one point. Indeed, the ruling in Collins's Case L. and C. 471 was that an offender cannot be guilty of an attempt to steal his own umbrella when he mistakenly believes that it belongs to another. Although the "moral guilt" for the attempt and the actual crime were the same, there was a distinction between the harm caused by a theft and the harmlessness of an impossible act. This principle was directly overruled in England with the rulings R v Ring and R v. Brown The example from R v Brown of an attempt to steal from an empty pocket is now a classic example of illustrating the point that impossibility is no defense to the crime of attempt when the conditions creating the impossibility are unknown to the actor. This principle has been codified in the Model Penal Code:
