Withdrawal as a defense to conspiracy is a type of legal defense used in criminal law. It is a defense where a defendant seeks to prove they withdrew from a conspiracy before any criminal activity took place, and thus are not guilty of any criminal activity in the conspiracy. There are two types of withdrawal as a defense to conspiracy: affirmative withdrawal and implied withdrawal. Affirmative withdrawal requires the defendant to prove that they took affirmative steps to remove themselves from the conspiracy and notify other conspirators that they are no longer participating. Implied withdrawal requires the defendant to prove that their behavior indicated that they had withdrawn from the conspiracy, even if they did not take explicit steps to withdraw from the conspiracy.
