If a person is guilty of conspiracy, as defined in ORS 161.450, and knows that a person with whom the person conspires to commit a crime has conspired or will conspire with another person or persons to commit the same crime, the person is guilty of conspiring with such other person or persons, whether or not the person knows their identity, to commit such crime. [1971 c.743 §60] 161.460 Renunciation as defense to conspiracy. (1) It is a defense to a charge of conspiracy that the actor, after conspiring to commit a crime, thwarted commission of the crime which was the object of the conspiracy, under circumstances manifesting a complete and voluntary renunciation of the criminal purpose of the actor. Renunciation by one conspirator does not, however, affect the liability of another conspirator who does not join in the renunciation of the conspiratorial objective. (2) The defense of renunciation is an affirmative defense. [1971 c.743 §61] 161.465 Duration of conspiracy. For the purpose of application of ORS 131.125: (1) Conspiracy is a continuing course of conduct which terminates when the crime or crimes which are its object are completed or the agreement that they be committed is abandoned by the defendant and by those with whom the defendant conspired. (2) Abandonment is presumed if neither the defendant nor anyone with whom the defendant conspired does any overt act in pursuance of the conspiracy during the applicable period of limitation.
If an individual abandons the agreement, the conspiracy is terminated as to the individual only if and when the individual advises those with whom the individual conspired of the abandonment or the individual informs the law enforcement authorities of the existence of the conspiracy and of the participation of the individual therein.
