Merger After Co-Conspirator Completion
Ines Ibarra and Igor Ito agreed to steal electronics containers from a docked ship and discussed disabling security seals. Igor later used the method to divert multiple containers successfully. The completed theft absorbed the preliminary agreement under the merger doctrine so that Ines faced liability only for the felony theft.
Purpose Requirement in Attempt
Isaiah Ishikawa entered a restricted server area intending to copy trade secrets for a foreign buyer. He accessed files but was stopped before transmission. His specific purpose to aid the buyer distinguished the attempt from otherwise lawful conduct and supported inchoate liability.

United States v. Bailey444 U.S. 394 (1980)
Redacted Confession in Conspiracy Trial
Ilana Isaacs confessed that she and two others planned to assault a rival. At trial the prosecution introduced a redacted version naming only Ilana. The redaction rendered the statement nonsensical for proving the conspiracy because it eliminated reference to the required agreement with confederates.
Gray v. Maryland523 U.S. 185 (1998)
Solicitation Through Informant
Ismael Ibrahim told an undercover officer he would pay to have a witness eliminated. The officer recorded the conversation but never intended to carry out the crime. The inchoate solicitation was complete upon the purposeful request even though the target offense remained unperformed.

Wharton Rule in Gambling Conspiracy
Ivan Ivanov and four others agreed to operate an illegal gambling business requiring more than five participants. The agreement itself supplied the basis for conspiracy liability separate from the completed gambling offenses because the inchoate offense targeted the collective planning stage.

Common questions
Frequently Asked
4
Does the common law merger doctrine prevent separate conviction for conspiracy once the target offense is completed by a co-conspirator?+
Yes. At common law the merger doctrine treats conspiracy as a preliminary misdemeanor that merges into the completed felony when any participant in the agreement finishes the principal offense. The doctrine prevents multiple punishments for what is essentially one criminal transaction progressing from planning to execution.
Supporting sources
Does merger apply when the defendant personally fails in an attempt but a solicited participant later completes the offense?+
Yes. The merger doctrine focuses on completion by any actor connected to the inchoate conduct rather than requiring the defendant to finish the crime. Solicitation creates the link that allows the completed felony to absorb the preliminary charges.
Supporting sources
Is an agreement alone sufficient to complete conspiracy at common law without proof of an overt act?+
Yes. Under the traditional common law definition the agreement itself constitutes the culpable act and the prosecution need not prove any additional overt act.
Supporting sources
Does feigned agreement by one party prevent formation of common law conspiracy?+
Yes. Common law conspiracy requires at least two participants who genuinely share a criminal objective. If one party merely pretends to agree and lacks actual intent the bilateral requirement fails and neither party can be convicted.

Nor, the court noted, is a specific…
