Attempt and conspiracy

Attempt at the Edge: From Purposeful Step to Merger

Attempt punishes purposeful movement toward a completed offense before the target crime is finished, so the decisive questions are intent, conduct, interruption, and any statutory defense. A defendant ordinarily must intend to commit the target offense, not merely intend to perform the act that happened to be criminal. Thus, accidentally firing a gun at a person cannot be attempted murder, while intentionally firing at a person with an unloaded gun may be attempted murder.

Run the analysis in this order:

  1. Identify the target offense and ask whether it was completed. If completed by the same defendant, prosecute the substantive offense; attempt ordinarily merges into the completed offense and is not a separate conviction. Attempt does not merge into conspiracy.

  2. Ask whether the defendant had the required purpose. Buying burglary tools intending to sell them is not attempted burglary. Buying them intending to break into a particular house may establish the required mental state, even if the burglary never occurs.

  3. Locate the act beyond preparation. Under a substantial-step formulation, the act must strongly corroborate the criminal purpose. Buying ordinary supplies, scouting generally, or merely discussing a plan may remain preparation. Arriving at the intended location with specialized tools, lying in wait for the victim, or taking a substantial step in the planned sequence is stronger evidence. If the supplied statute uses dangerous proximity or another formulation, apply its language.

  4. Test interruption and renunciation. Police arrest, an arriving victim, a locked door, or a decision to postpone generally shows that the crime stopped because circumstances intervened. A statutory abandonment or renunciation defense usually requires complete and voluntary withdrawal before completion. Fear of detection, increased difficulty, or a desire to wait for a better opportunity is not voluntary abandonment. Some statutes additionally require the defendant to thwart the crime; the supplied provision controls.

Impossibility is a frequent near miss. Factual impossibility is ordinarily no defense: the defendant is liable when the intended conduct would have been criminal under the facts as the defendant believed them to be. An unloaded gun, an empty pocket, or a victim who was already dead can fit this principle. Legal impossibility traditionally exists when the facts as the defendant believed them would not constitute a crime at all. A statute that expressly rejects impossibility or covers circumstances as the defendant believed them to be eliminates that defense. Do not call every failed attempt “legal impossibility.”

Conspiracy and Its Reach: Agreement, Withdrawal, and Foreseeable Crimes

Conspiracy analysis begins with the agreement, not with how far participants advanced toward the planned offense. Look for facts such as “agreed,” “planned together,” coded messages confirming a shared objective, division of roles, or coordinated purchases. A completed target crime is unnecessary. Mere presence, knowledge of another person’s plan, or supplying ordinary goods without criminal purpose does not establish agreement.

Ask four questions:

  1. Was there an agreement? It may be express or inferred from coordinated conduct, but the parties must share the unlawful objective. A seller who knows a buyer may misuse a product ordinarily lacks the required agreement.

  2. Did the defendant intend the unlawful objective? The defendant must intend that the target offense be committed. Knowledge that others intend a crime is not enough. A feigning undercover officer can matter under a bilateral statute requiring a genuine agreement of two criminal participants; under a unilateral statute, the defendant’s belief that another agreed may suffice.

  3. Was the required act performed? Many statutes require an overt act in furtherance, which can be lawful and minor, such as buying supplies or renting a vehicle. Any conspirator’s qualifying act may satisfy the requirement. Common-law conspiracy may not require an overt act, so read the supplied provision.

  4. What consequence is being charged? Conspiracy is complete when its statutory elements are satisfied. It generally does not merge into the completed target offense. A defendant may therefore face both conspiracy and the substantive crime, subject to the supplied statute and applicable constitutional limits.

Withdrawal is not the same as denying that a conspiracy ever existed. Withdrawal after agreement ordinarily does not erase the completed conspiracy. It may terminate the defendant’s membership for later consequences if the defendant takes the steps required by governing law, such as communicating withdrawal to every conspirator or making reasonable efforts to prevent the crime. Mere silence, nonattendance, or saying “I changed my mind” may be insufficient.

Renunciation can be a statutory defense to conspiracy when it is complete and voluntary and when the statute requires the defendant to thwart the conspiracy’s success. Withdrawal motivated by fear of arrest or by the plan becoming inconvenient is ordinarily not voluntary. Impossibility usually does not defeat conspiracy when the parties agreed to pursue conduct they believed to be criminal. The narrow Wharton’s rule exception may apply when the target offense necessarily requires concerted participation by the same number of people as the alleged conspiracy; additional participants or a statute displacing the rule can change the result.

Coconspirator liability for substantive crimes is a separate inquiry from proving the conspiracy. Under the traditional rule, a conspirator may be liable for another conspirator’s substantive offense when the offense:

  • occurs while the defendant remains a member of the conspiracy;
  • is committed in furtherance of the conspiracy’s objective; and
  • is reasonably foreseeable from the agreement.

The rule does not make a conspirator liable for every crime committed by a confederate. A planned robbery can support liability for the robbery, and perhaps a foreseeable use of force, but an unexpected personal vendetta or an unrelated crime falls outside the agreement’s foreseeable scope. Effective withdrawal before the later offense can also cut off this derivative liability, even though it does not undo the conspiracy already formed.

Supplied Text in Action: One Withdrawal That Does Not Work

Assume the supplied provision provides:

Attempt. A person commits attempt if, with purpose of committing an offense, the person takes a substantial step strongly corroborative of that purpose. It is no defense that the offense could not be completed because an attendant circumstance was as the person believed it to be. Renunciation is a defense only if the person completely and voluntarily abandoned the criminal effort before its completion; abandonment motivated by increased difficulty or risk of detection is not voluntary.

Conspiracy. A person commits conspiracy if the person agrees with another that one or more of them will commit an offense and intends that the offense be committed, and any conspirator performs an overt act in furtherance. Withdrawal is not a defense to conspiracy, but a conspirator who, before the substantive offense, completely and voluntarily withdraws by informing every other conspirator and makes reasonable effort to prevent it is not liable under the next paragraph for that later offense.

Coconspirator offenses. A conspirator is liable for another conspirator’s substantive offense if committed during the conspiracy, in furtherance of its objective, and reasonably foreseeable from the agreement. This liability does not include an offense committed after effective withdrawal.

Mara and Sol agree to rob a pharmacy, with Mara entering the pharmacy and Sol serving as lookout.

Mara obtains a fake employee badge and a handgun for the robbery.

Sol later learns that police patrols have increased and tells no one except Mara, “I am out; this is too risky.”

Sol does not contact the police, warn the pharmacy, or otherwise try to prevent the robbery.

Mara and Tessa, who has joined the plan, rob the pharmacy. Tessa unexpectedly shoots a guard who resists.

Practice

Under the supplied provision, what is the best conclusion about Sol’s liability?

Pressure-Test Questions: Three Distinctions Under Time

Practice

Rina intended to burglarize a closed store. She bought gloves, drove to the store, and placed a pry bar against the rear door before police arrested her; she never entered or damaged the door. Is Rina guilty of attempted burglary?

Owen and Pia agree to steal a shipment, and Pia rents a van for the plan. Owen later tells Pia that he wants nothing more to do with it, but the shipment is stolen the next day. Which statement is most accurate?

Jules and Kira agree to rob a store, and Kira supplies a floor plan while remaining in the conspiracy. Jules commits the planned robbery, then unexpectedly shoots a resisting bystander for a personal reason unrelated to the plan. The shooting was not discussed and was not reasonably foreseeable. What is the best conclusion?

High-Yield Points - ⚡ Biggest Takeaways

Attempt requires purposeful conduct beyond preparation; a completed target offense absorbs the attempt. Conspiracy turns on agreement, intent, and any required overt act, not completion of the planned crime. Coconspirator liability reaches only foreseeable offenses in furtherance while membership continues.

Practice Questions: Attempt and conspiracy

  1. 1. Using only the supplied file and legal resources, prepare an advisory letter explaining which charges the prosecution may retry. Address when jeopardy attached, the effect of the defense-requested mistrial, whether the prosecutor's conduct triggers the intent-to-provoke limitation, and the consequences of the firearm acquittal and robbery deadlock. Give realistic advice about the strength of a motion to bar retrial and identify the most useful remaining investigation concerning the prosecutor's intent. Do not use outside law.

    • 2. Using only the supplied file and legal resources, prepare an advisory client letter evaluating the prosecution's murder theory, Jordan's self-defense argument, the causation issue, and the proposed manslaughter resolution. Explain the principal risks in plain language and recommend a negotiation position without predicting a certain verdict.

              • 7. Police arrested a driver on probable cause for leaving the scene of a collision. At the station, an officer placed the driver in an interview room and said, without giving warnings, “The damaged car contained a child’s backpack.” The driver remained silent. Twenty minutes later, while transporting the driver to a detention facility, two officers discussed between themselves that the injured child might die without information about what happened. The officers knew the driver could hear them but had not planned the conversation to obtain a response. The driver interrupted and said, “I was looking at my phone when I hit the car.” The prosecution seeks to use the statement in its case-in-chief. The driver has not alleged coercion. Is the court likely to suppress the statement?

                • A. Yes, because any statement made after an unwarned custodial remark is excluded from the prosecution’s case-in-chief.
                • B. Yes, because the officers should have known that discussing the injured child was reasonably likely to elicit an incriminating response.
                • C. No, because the officers’ conversation was not interrogation and the driver volunteered the statement.
                • D. No, because warnings are required only after formal criminal charges have been filed.
                Show answer

                Answer: C. No, because the officers’ conversation was not interrogation and the driver volunteered the statement.

                No, because the officers’ conversation was not interrogation and the driver volunteered the statement. - Miranda bars unwarned statements made during custodial interrogation, including its functional equivalent, but not volunteered statements. - As in Rhode Island v. Innis, the officers spoke to each other rather than questioning the driver, and the facts do not show they should have known their conversation was reasonably likely to elicit his interruption. Yes, because any statement made after an unwarned custodial remark is excluded from the prosecution’s case-in-chief. - The officer’s earlier remark about the child’s backpack drew no response from the driver. - That remark does not automatically exclude a later, volunteered statement; the driver has not alleged coercion. Yes, because the officers should have known that discussing the injured child was reasonably likely to elicit an incriminating response. - The reasonably likely to elicit standard can apply even when officers speak to each other within a suspect’s hearing. - Here, their unplanned conversation, without a stated reason to expect the driver to respond, does not establish the functional equivalent of questioning. No, because warnings are required only after formal criminal charges have been filed. - Miranda warnings are required before custodial interrogation, regardless of whether formal charges have been filed. - The statement is admissible because it was volunteered, not because the driver had yet to be charged.

              • 8. During an argument, a man intentionally stabbed another person in the abdomen, intending to kill him. The victim was taken to a hospital, where a physician negligently failed to diagnose internal bleeding that ordinarily would have been detected and treated. The victim died from the combined effects of the wound and the untreated bleeding. A medical expert concluded that the victim would have survived with competent treatment, but the physician's negligence was not extraordinary or intentionally harmful. The prosecutor is considering a murder charge against the attacker. Which of the following is the strongest conclusion regarding causation?

                • A. The original attacker is liable for murder because the stabbing remained an actual and proximate cause of the victim's death.
                • B. The original attacker is liable only for attempted murder because negligent medical treatment necessarily breaks the causal chain.
                • C. The original attacker is liable only for manslaughter because the physician, rather than the attacker, performed the act immediately preceding death.
                • D. The original attacker is not liable for homicide unless the prosecution proves that the physician's treatment complied with professional standards.
                Show answer

                Answer: A. The original attacker is liable for murder because the stabbing remained an actual and proximate cause of the victim's death.

                The original attacker is liable for murder because the stabbing remained an actual and proximate cause of the victim's death. - The stabbing was an actual cause of death: without the wound, there would have been no wound-related bleeding to leave untreated. - Ordinary negligent treatment of the wound does not supersede the stabbing as a cause, and the attacker acted with intent to kill. The original attacker is liable only for attempted murder because negligent medical treatment necessarily breaks the causal chain. - Negligent treatment does not necessarily break the causal chain when the original wound remains a cause of death. - The expert’s view that competent treatment would have saved the victim does not erase the stabbing’s role in the death that occurred. The original attacker is liable only for manslaughter because the physician, rather than the attacker, performed the act immediately preceding death. - Causation does not depend on who acted last; the wound and untreated bleeding combined to cause death. - The attacker’s intent to kill supports murder rather than reducing the offense to manslaughter because of the physician’s later negligence. The original attacker is not liable for homicide unless the prosecution proves that the physician's treatment complied with professional standards. - The prosecution must prove the stabbing actually and proximately caused death, not that the physician provided competent care. - The physician’s negligent failure to diagnose bleeding does not preclude homicide liability when the stabbing remained a cause of death.

              Flashcards: Attempt and conspiracy

              1. 1. What crimes may an accomplice be liable for beyond the crime he intended to facilitate?

                Show answer

                Under the majority/natural-and-probable-consequences approach, an accomplice is liable for the target crime and for other crimes committed by the principal that are reasonably foreseeable consequences of the aided conduct. The minority approach limits liability to crimes the accomplice intended to facilitate.

              2. 2. What are the majority-law elements of criminal attempt?

                Show answer

                Attempt requires intent to commit the target crime plus a substantial step toward its commission that strongly corroborates the criminal purpose. Mere preparation is insufficient.

              3. 3. Under the supplied rule, what is the primary distinction between accomplice liability and accessory after the offense, regarding timing and mental state?

                Show answer

                Accomplice liability applies to purposeful assistance given before or during the offense. Accessory after the offense applies to knowing, purposeful assistance given after completion of a felony, with the purpose of helping the offender avoid legal consequences.

              4. 4. What is the majority rule on factual versus legal impossibility as a defense to attempt?

                Show answer

                Factual impossibility is generally not a defense: a person may be guilty when the intended crime could not be completed because of circumstances unknown to the person. Legal impossibility is a defense when the intended conduct, even if completed as intended, would not be criminal.

              5. 5. Under the majority rule, when can abandonment or renunciation defeat attempt liability?

                Show answer

                At common law, abandonment after the defendant has completed the acts required for attempt is generally no defense. Under the modern majority of statutes, abandonment may be a defense only if the defendant completely and voluntarily renounces the criminal purpose before the crime is completed.

              6. 6. What is the Pinkerton rule for a conspirator’s liability for another conspirator’s substantive crime?

                Show answer

                Under the majority rule, a conspirator is liable for a substantive offense committed by a co-conspirator if it was committed in furtherance of the conspiracy and was a reasonably foreseeable consequence of it. The conspirator need not personally participate in or know of the specific offense.

              7. 7. What are the elements of being an accessory after the fact?

                Show answer

                An accessory after the fact, a separate offense from the underlying crime, knowingly assists the offender after the crime is completed with the purpose of helping the offender avoid arrest, trial, conviction, or punishment. The accessory must know that the offender committed a felony or, under some statutes, another specified serious offense.

              8. 8. What are the elements of accomplice liability under the majority rule?

                Show answer

                The defendant must intentionally aid, encourage, or facilitate the principal’s crime, with intent to assist and intent that the crime be committed. Mere presence, knowledge, or failure to intervene generally is not enough.

              9. 9. What is the majority rule for liability for an unsuccessful solicitation?

                Show answer

                Solicitation requires asking, encouraging, or commanding another person to commit a crime, with intent that the person commit it. The crime is complete when the request is made, even if the other person refuses.
