22-4A-4. Renunciation of criminal intent--Requirements.
No person may be convicted of criminal solicitation if, under circumstances manifesting a voluntary and complete renunciation of the defendant's criminal intent, the defendant:
(1)Notified the person solicited of his or her renunciation; and
(2)Gave timely and adequate warning to the law enforcement authorities or otherwise made a substantial effort to prevent the commission of the criminal conduct solicited.
The burden of injecting this issue is on the defendant, but this does not shift the burden of proof.
