⚡ 10-Second Rule
When two people agree to commit a crime, the agreement itself is a separate crime.
🧒 ELI-10 Scene
Nora and her brother Theo shake on a plan: sneak downstairs at midnight and eat the birthday cake early. Theo even sets his alarm clock — one small move toward the plan. Dad finds out before midnight. Are they safe because no cake was touched? Nope. In this house, making the pact is its own offense. And here's the scary part for Nora: if Theo also swipes a soda while grabbing the cake, Dad blames Nora too. Teammates own each other's moves.
⚖️ Actual Rule
Conspiracy is an agreement between two or more persons to commit an unlawful act, with the intent to agree and the intent to achieve the unlawful objective. At common law, the agreement alone completed the crime and no overt act was required; the majority of modern statutes add an overt-act element, which any single conspirator may satisfy with even a trivial act — the federal statute, 18 U.S.C. § 371, requires that a conspirator "do any act to effect the object of the conspiracy." The common law takes a bilateral view, requiring at least two genuine parties, so a feigned agreement with an undercover officer creates no conspiracy; the Model Penal Code § 5.03 takes a unilateral view under which one person's genuine agreement suffices (paraphrased). [NJ-VARIANT: flagged for future Eli Explains NJ Law module] Under Pinkerton v. United States, 328 U.S. 640 (1946), each conspirator is liable for co-conspirators' crimes committed in furtherance of the conspiracy and reasonably foreseeable to its members: "the overt act of one partner may be the act of all without any new agreement specifically directed to that act." Withdrawal is no defense to the conspiracy itself, but timely notice of withdrawal to all co-conspirators cuts off liability for their subsequent crimes. Under Wharton's Rule, there is no conspiracy where the offense by definition requires exactly two participants — such as dueling or bigamy — unless more parties than the crime requires join in. Conspiracy never merges into the completed offense, so a defendant may be convicted of both.
ELI-10 translation: the handshake is the crime, and every teammate answers for the team's foreseeable moves.
🔍 Ask These Questions
- Was there a genuine agreement between two or more people to do something unlawful? (Did they truly join a plan, even without saying the words out loud?)
- Did each have intent to agree and intent to achieve the criminal goal? (Did each person actually want the plan to succeed?)
- In a bilateral jurisdiction, were there two real criminals — or was one an undercover officer? (A pretend partner means no true deal at common law.)
- Does the statute require an overt act, and did any conspirator do even a small one? (One teammate's tiny step counts for everyone.)
- Is a co-conspirator's extra crime foreseeable and in furtherance of the plan under Pinkerton? (Would a sensible planner see that crime coming as part of the job?)
- Did anyone withdraw by telling all partners in time? (Quitting loudly stops blame for future crimes, but never erases the original deal.)
- Does Wharton's Rule or the no-merger rule change the count? (Two-person-by-definition crimes can't be conspiracies, and conspiracy stacks on top of the finished crime.)
⚠️ Bar Trap
Exam language: Examiners charge a conspirator with a substantive offense she never discussed, never assisted, and never knew about, inviting the answer that liability requires personal agreement to that crime. Under Pinkerton, personal participation is unnecessary: liability attaches to any co-conspirator's crime that was reasonably foreseeable and in furtherance of the conspiracy. The mirror-image trap is stacking convictions — conspiracy does not merge, so conviction for both conspiracy and the completed offense is proper.
ELI-10: Joining the team means owning the team's predictable plays, even ones you never called. And finishing the crime doesn't swallow the deal — both counts stick.
🧪 Question
Marcus and Lena agreed to burglarize a pharmaceutical warehouse and steal cases of prescription painkillers. Under the plan, Lena would disable the warehouse alarm and Marcus would carry out the cases. The night before the burglary, without telling Lena, Marcus stole a cargo van from a supermarket parking lot so the two would have a vehicle large enough to haul the cases away. Police arrested both before the burglary occurred. Lena is charged with theft of the van in a jurisdiction that follows Pinkerton.
Is Lena guilty of the van theft?
(A) No, because she neither agreed to nor knew about the theft of the van. (B) No, because stealing the van was not the object of the conspiracy. (C) Yes, because the theft was reasonably foreseeable and committed in furtherance of the conspiracy. (D) Yes, because conspirators are strictly liable for every crime any member commits.
Answer: (C). Hauling away cases of stolen drugs predictably requires transport, so acquiring a getaway vehicle is both in furtherance of the burglary scheme and reasonably foreseeable. Under Pinkerton, Marcus's act is attributed to Lena without any new agreement.
💡 Why the Wrong Answers Are Wrong
- (A) demands personal agreement or knowledge, which Pinkerton expressly dispenses with for foreseeable crimes in furtherance of the scheme.
- (B) wrongly limits liability to the conspiracy's target offense; Pinkerton reaches crimes committed to accomplish that target.
- (D) overshoots — Pinkerton liability is bounded by foreseeability and furtherance, not strict liability for anything a partner does.
- ELI-10: The misconception is thinking you only answer for crimes you personally signed up for. Joining the plan signs you up for its predictable side jobs too.
