An individual may be culpable of solicitation if he or she encourages another to commit a particular offense. Solicitation is a specific intent crime in the United States. The solicited individual need only attempt to complete the crime for solicitation to exist.
There is one primary defense to solicitation:
- Renunciation - In order to use this defense, the defendant must 1) renounce intent for principal to commit crime and 2) discourage or otherwise stop principal from completing crime,
Example: A person is guilty of solicitation if:
- his purpose is to promote or facilitate the commission of a substantive offense; and
- with such purpose, he commands, encourages or requests another person to engage in conduct that would constitute the crime, an attempt to commit it, or would establish the other person's complicity in its commission or attempted commission.
