Attempt - The Question of Impossibility

The Question of Impossibility

See People v. Lee Kong, State v. Mitchell, United States v. Thomas, James v. United States (2007), Impossibility defense

There is a distinction between "factual impossibility" and "legal impossibility". Factual impossibility is rarely a defense. A standard policing strategy is the use of an agent provocateur to offer temptation to suspected criminals. In some countries, evidence resulting from entrapment is inadmissible. Nevertheless, undercover police officers do sell real or fake contraband such as illegal drugs or guns, as a means of exposing criminal activity. Some consider the use of fake material as a slightly safer way to catch criminals, rather than risk the real contraband falling into the wrong hands. But if there is no actual contraband and the actus reus of the full offense is "possession" of prohibited materials, there can be no criminal possession. Can there be an attempt to possess when, in the circumstances, it was impossible to follow through to commit the full offense? The answer is that mistakes of fact are almost never a defense, as in People v. Lee Kong, and State v. Mitchell, for example.

England and Wales

Section 1(2) of the Criminal Attempts Act 1981 applies the Act even though the facts are such that the commission of the offence is impossible so long as, under section 1(3), the defendant believes that he is about to break the law and intends to commit the relevant full offence. This reverses the House of Lords' decision in Haughton v Smith, which had held it to be a good defence if the intended crime was factually or legally incapable of fulfillment. This change in the law avoids any problem in an early arrest because, once in police custody, it is extraordinarily difficult to commit the full offence. Further, both the incompetent criminal who fails because the means adopted are inadequate (e.g. intends to poison a victim but the amount administered is harmless, or makes a false statement that does not deceive the intended victim) and the unlucky thief who find the pocket or purse empty, can now be convicted.
