Other Roles of the Overt Act
The preceding sections treat the overt act as the step that completes a conspiracy wherever a statute or the Model Penal Code demands one. The act also raises a question about its own legal status, and the answer explains why it turns up in places that have nothing to do with completion. Statutes that require an overt act typically say that one must be proved, and most can be read two ways: the act may be a part of the offense itself, or it may be only an element of proof, a piece of evidence that the agreement exists and is operating. A few statutes make the choice in their text, but most leave it open.1 The Supreme Court currently regards the act as evidence of the offense, although that has not always been the rule.2
The evidence reading fits what the act is for. The Supreme Court explained in Yates v. United States that the function of the overt act is simply to manifest "that the conspiracy is at work," so that the plan is neither a project resting solely in the minds of the conspirators nor a fully completed operation no longer in existence.3 An act that shows the conspiracy at work gives additional proof that the agreement is real and that the parties mean to carry it out. For that reason the requirement is often described as more procedural than substantive, even in the jurisdictions that impose it.4 Because the act operates as proof, the choice between element and evidence rarely changes the outcome of a case. The label matters in only three settings:
- the statute of limitations;
- jurisdiction or venue;
- whether the jury must be unanimous about which act was committed.5
The unanimity setting shows how little the label controls. In federal prosecutions under the general conspiracy statute, 18 U.S.C. § 371, an overt act must be proved. In United States v. Kozeny the Second Circuit held that the government must prove at least one overt act because it is an element of the crime, yet the jury need not agree on which act it was, since the identity of the particular act is a "brute fact" and not itself an element.6 The court relied on Richardson v. United States, which allows jurors to differ over the underlying brute facts that make up an element so long as they agree that the element is established.7 The Fifth and Seventh Circuits support that position, while decisions in the Eighth and Ninth Circuits are less certain.8 So even a court that calls the act an element does not carry the label to the point of demanding agreement on a single act.
The label also does not decide whether the crime is complete. Calling the act evidence makes it no less necessary, because most states with an overt-act statute require that an act in furtherance of the plan be proved, and the federal statute does so as well.9 The trap on an exam stem is reading "evidence" to mean "unnecessary". Where the jurisdiction requires an overt act, the prosecution must prove one. The element-versus-evidence debate affects only the side questions listed above.
Because the act is the visible sign that a conspiracy is active, lawmakers use it as a convenient anchor for procedural questions about where and when a conspiracy exists. Two such uses appear in the Model Penal Code. The first limits the places in which a conspiracy may be charged, and the second concerns how long a conspiracy lasts and how a participant leaves it. The next two sections treat them as brief bridges to topics that other readings cover in full.
Venue Under the MPC
The overt act has one more job in the Model Penal Code, and it has nothing to do with whether the conspiracy is complete. Venue is the question of which county may host the prosecution, and § 5.03(4)(b)(i) answers it for conspiracy with two connecting points. No defendant may be charged in any county other than one in which he entered into the conspiracy or one in which an overt act pursuant to the conspiracy was done by him or by a person with whom he conspired.11 The clause sits in the subsection on joint prosecutions of conspirators, which also contains rules on severance and on the use of one defendant's acts and declarations against another, but those belong to the treatment of joinder and are not taken up here.12
The rule needs two anchors because an agreement has no physical location the way a battery does, so the law must say where a conspiracy happened. The Code picks the two places where the conspiracy demonstrably existed: the county where the defendant joined it, and the county where the plan showed itself through an act. Confining venue to those places keeps a defendant from being tried in a county that has no connection to the plan. The act that counts need not be the defendant's own. Conspirators act for one another, so an act by one partner in carrying the common plan forward is treated as the act of all, and the same attribution that completes the offense under an overt-act statute also widens the places where it may be tried.13 A defendant who never left County A can therefore be charged in County B because a partner bought equipment there.
The venue clause also does not ask whether the act was needed for liability. It looks only to whether an overt act pursuant to the conspiracy was done in the county.14 For a conspiracy to commit a first- or second-degree felony, where the agreement alone completes the offense, an act that happens to occur is surplus for liability yet still supplies venue where it was done. With no act at all, only the county of agreement remains.
Students lose points here by reading venue as available wherever the planned crime was aimed. Under the Code's text a county qualifies only through one of the two connections, an agreement entered into there or an overt act done there by the defendant or a co-conspirator, and the target of the plan, the victim's home, and the defendant's residence supply no basis unless one of those connections is also present.
Duration and Abandonment
The venue clause uses the overt act to say where a conspiracy may be charged, and the duration clause uses the same act to say how long a conspiracy lasts. Section 5.03(7)(a) treats conspiracy as a continuing course of conduct that terminates in one of two ways: the crimes that are its object are committed, or the agreement that they be committed is abandoned by the defendant and by those with whom he conspired.16 The provision is written for purposes of § 1.06(4), the Code's rule on limitation periods, so the question it answers is practical: when does the clock for prosecuting a conspiracy start to run?17 The continuing-course definition follows from how partners in crime behave. So long as the partnership continues, the partners act for one another in carrying it forward, which means the conspiracy does not end simply because the original agreement lies in the past.18 The word and in the abandonment clause carries the same logic. One member's private change of heart leaves the enterprise running, so the conspiracy ends by abandonment only when the defendant and every person he conspired with have given it up.
Abandonment is a state of mind, and a state of mind is hard to prove from the outside. Section 5.03(7)(b) therefore ties it to something observable: abandonment is presumed if neither the defendant nor anyone with whom he conspired does any overt act in pursuance of the conspiracy during the applicable period of limitation.19 Here the overt act serves as a marker of a living conspiracy. An act in pursuance of the plan shows that the plan is still being worked, and a silence as long as the limitation period is treated as evidence that the plan has died. Without that presumption, a conspiracy that never formally ended would never stop, and the limitation clock for it would never start. With the presumption, the conspiracy's lifespan follows activity that can be shown in court.
The text of the presumption has several features that decide how it works. The act may come from anyone in the conspiracy, because the provision asks whether the defendant or anyone with whom he conspired did an overt act, so the attribution rule that lets one partner's act count for all also lets one partner's act keep the whole enterprise alive.20 The act need not be large, since the standard is any overt act in pursuance of the plan, and, as the earlier discussion of what counts showed, a step as ordinary as buying supplies or making a call is enough to show that the plan is still being worked.21 The silence must also cover the entire period of limitation, so a quiet stretch shorter than that period raises no presumption at all. Finally, the provision does not depend on the grade of the object. A conspiracy to commit a first- or second-degree felony needs no overt act for liability under § 5.03(5), yet the overt act still measures whether that conspiracy remains alive.22
Students lose points on this provision by reading the presumption as a rule about completion. Whether the conspiracy offense has been committed is settled by the agreement, together with an overt act where § 5.03(5) requires one.23 Section 5.03(7) asks a later question about a conspiracy that already exists: is it still running, or is it treated as over for purposes of the limitation period?24 A long silence therefore does not undo a conspiracy that was already formed. It signals that the plan has died, and the clock is treated accordingly. The presumption is not an individual defense either. At common law there is no abandonment defense at all, because the crime is complete with the agreement and no later act can exonerate the actors.25 The Code's separate renunciation defense in § 5.03(6) belongs to a defendant who thwarts the conspiracy, and it is a different inquiry from whether anyone did an overt act.26 How a single member ends his own liability is the subject of the withdrawal discussion, and the duration clause does not answer it.
