Status of the Principal
Subsections (1) through (4) of § 2.06 explain how a defendant becomes accountable for what another person does, but they leave a practical question open: what happens to that accountability when the person who actually performed the conduct is not a convenient defendant? The actor may never be charged, may be convicted of a lesser offense, may hold an immunity, may be legally incapable of committing the offense, or may have been acquitted by a jury. If the accomplice's liability rose and fell with the fortunes of the actor, each of these accidents of procedure or status would free the accomplice as well. The Code closes that gap with two rules, one in subsection (7) and one in subsection (5), and they answer different sides of the problem.
Subsection (7) concerns the position of the person who committed the conduct. An accomplice may be convicted on proof that the offense was committed and that the accomplice took part in it, even though the person claimed to have committed it has not been prosecuted or convicted, has been convicted of a different offense or a different degree of the offense, has an immunity, or has been acquitted.1 Subsection (5) concerns the accomplice's own position. A person who is legally incapable of committing a particular offense personally may still be guilty of it when another commits it by conduct for which the person is legally accountable, unless that result would be inconsistent with the purpose of the provision that creates the incapacity.2
Both rules rest on the same premise about what the prosecution of an accomplice has to prove. Accountability under the Code depends on two things: the conduct that makes up the offense, and the defendant's own complicity in it, measured by the defendant's own purpose and conduct under subsection (3). The result of someone else's trial, and the legal label attached to the actor or to the defendant, supply neither ingredient. The state therefore proves the offense through its own evidence at the accomplice's trial, and a separate courtroom's verdict or a defendant's disqualifying status adds nothing to what must be shown.3 Each rule still leaves complicity itself to be proved, and subsection (5) carries its own limit when the incapacity exists for a reason that liability would defeat. The next two parts take subsection (7) first, because it governs the more common situation of an actor who is unprosecuted, convicted of something else, immune, or acquitted, and then turn to subsection (5) and the accomplice who could not have committed the offense alone.
Unconvicted or Acquitted Principals
Subsection (7) answers a problem that arises whenever the person who performed the conduct is not in the same position as the defendant now on trial. It permits conviction of an accomplice on proof that the offense was committed and that the accomplice took part in it, even though the person claimed to have committed the offense has not been prosecuted or convicted, has been convicted of a different offense or a different degree of the offense, has an immunity to prosecution or conviction, or has been acquitted.4 Each item on that list is a separate way for the actor's legal fortunes to part company from the accomplice's. The subsection speaks to the actor's outcome, and its instruction is that none of the five outcomes decides the accomplice's case by itself.
The reason lies in what § 2.06(1) holds the accomplice responsible for. On the better reading, the word conduct in that subsection means the actor's performance of what the offense definition describes. It does not include the mental state with which the actor performed it, and it does not include the actor's guilt for performing it. The accomplice therefore answers for the actor's conduct together with the accomplice's own culpability.5 That reading fits the Code's concern with each person's individual blameworthiness. It is an interpretation of the text and not a settled holding, and a court that rejected it might require a guilty principal before convicting the accomplice, so the point is best presented as the prevailing reading with the contrary possibility noted.6
Once liability is tied to conduct plus the accomplice's own culpability, the actor's verdict has no work left to do. An acquittal can rest on a ground peculiar to the actor: the actor lacked the required mental state, raised a personal excuse, received immunity in exchange for cooperating, or simply drew a lenient jury. None of those grounds says anything about whether the defendant acted with the purpose of promoting or facilitating the offense, which is the question subsection (3) asks. If the accomplice's liability followed the actor's verdict, a person planning an offense would have a reason to choose as the actor someone with a ready personal defense, and the party who planned and equipped the crime could go free because of the sympathetic circumstances of the party who carried it out. Subsection (7) removes that incentive by making the accomplice's trial turn on the accomplice's own proof. The same reasoning covers the pretending principal: a defendant who assists an actor who cannot be convicted, because the actor lacks a mental state or has a personal excuse, can still be convicted under § 2.06.7
Subsection (7) does not turn accomplice liability into liability for a relationship. The derivative character of that liability survives: the prosecution must prove that someone actually committed the offense, since otherwise there is nothing for the defendant to have assisted, though it need not identify who the principal was.9 Derivative liability is also different from vicarious liability, because the accomplice is blamed only for intentional conduct designed to encourage or help, and never solely because of an association with the actor.10 At the accomplice's trial, then, the state proves two things with its own evidence: that conduct constituting the offense occurred, and that the defendant was an accomplice in it. What subsection (7) removes is the dependence on the actor's verdict, and the proof that the offense happened remains.
The list in subsection (7) includes conviction of a different degree for a further reason, which is how the Code grades. An accomplice is graded according to the conduct committed and the accomplice's own culpability, so the Code readily allows different punishment for the actor and the accomplice.11 A conviction of the actor on a lower degree, resting on a mitigating circumstance personal to the actor, therefore does not cap the grade of an accomplice whose own state of mind and assistance support a higher one. The reverse also holds, since an accomplice whose culpability is lower is graded lower than the actor. In both directions the verdict reached in the other person's case informs the accomplice's grade no more than it determines the accomplice's guilt.
A decision from outside the Code shows the same idea at work, though it is only an analogy. In State v. Truesdell, an Oklahoma court heard the appeal of a mother charged as an accessory after a twelve-year-old son shot her former husband ten times. The trial judge had dismissed the charge on the ground that a juvenile cannot commit a felony and so there was no crime for the mother to have been an accessory to. The appellate court reversed, reasoning that the son's youth went to his legal status and not to the facts of what happened, and that the question was whether the evidence showed a principal guilty of the crime charged, whether or not that principal was ever charged.12 The decision rests on Oklahoma law, under which an accessory after the fact commits a separate offense after the principal crime is complete. The Code likewise handles post-offense helpers through a separate offense rather than through § 2.06, which is why Truesdell illustrates the principle that the actor's legal status does not shield the helper without applying subsection (7) itself.13
The limit on subsection (7) follows from its own premise. The accomplice is accountable for the actor's conduct, so the actor must have engaged in conduct that constitutes the offense or an attempt to commit it. Where the person who was aided never gets that far, no conduct exists to attribute, and the accomplice route closes. The defendant's exposure then moves to the Code's attempt provision, which reaches a person who engages in conduct designed to aid another in a crime, or to conspiracy if the two acted in concert.14
Change one fact and the answer changes. Had Nolan driven the van to the pharmacy and been stopped at the door, Nolan's conduct would amount to an attempt, and Vega's purposeful help would make Vega an accomplice in that attempt, whatever happened to Nolan at trial.
On an exam stem the first error is to treat the principal's acquittal as ending the accomplice's exposure, so that a not-guilty verdict for the actor is read as a not-guilty verdict for the helper. The second error runs the other way and treats subsection (7) as dispensing with proof that the offense occurred, which it does not. The sound analysis separates the questions: first ask whether conduct constituting the offense or an attempt occurred, whoever performed it and however that person fared in court, and then ask whether the defendant was an accomplice in that conduct. A stem that tells you the actor was excused, immune, unprosecuted, or convicted of something else is signaling that the actor's outcome is not the issue, and a stem in which the aided person never acted is signaling that the accomplice route is unavailable.
Legally Incapable Accomplices
Subsection (7) dealt with the legal position of the person who performed the conduct. Subsection (5) turns to the defendant's own position. Some offenses are defined so that only a person with a particular status can commit them as principal, such as a public official, a licensed professional, or a member of some regulated group. A defendant outside that group could never carry out the offense alone, and it is tempting to conclude that this ends the matter. Under the Code it does not. A person who is legally incapable of committing a particular offense personally may still be guilty of it if another person commits it by conduct for which the defendant is legally accountable, unless that liability would be inconsistent with the purpose of the provision establishing the incapacity.16
The default follows from what an accomplice is actually held to account for. The defendant answers for the conduct of the person who performed the offense, because the defendant acted with the purpose of promoting or facilitating it. That conduct is performed by someone who has the required status, so the status element is satisfied at the place where the offense definition needs it. Nothing in the logic of accountability requires the defendant to share the status as well, because the defendant is not charged with performing the act personally. The practical stakes are plain. Offenses limited to a status group are often the ones in which an outsider has the strongest motive to arrange the conduct, as when a private party profits from what an official does. If the outsider's lack of status were a defense, the outsider could solicit, finance, and direct the entire offense and stay beyond the law's reach precisely because the offense could not be committed alone, leaving only the insider exposed.
The exception exists because not every incapacity is a mere description of who performs the act. Some incapacity provisions are written to exempt a group from liability entirely, perhaps because the legislature regards its members as the people the offense is meant to protect, or because it wants them free to deal with the other party and to report wrongdoing without risk of prosecution. If the general accomplice provisions could be read over such an exemption, any exempt person who encouraged or helped the offense in any way could be convicted of the very offense the legislature put beyond reach. A general rule would then undo a specific choice. Subsection (5) prevents that result by yielding when liability would be inconsistent with the purpose of the provision establishing the incapacity.18 The question is therefore why the incapacity exists, and the wording of the incapacity alone does not answer it.
The two scenes share the same structure: a defendant who cannot commit the offense alone, and another person who does commit it. What separates them is the reason for the incapacity. In the first scene the status limit only describes who can perform the act, so the outsider's accountability fills a gap. In the second scene the incapacity is itself the legislature's grant of protection, and accountability would empty it. The next section on statutory exclusions shows the Code reaching a similar result for victims and for persons whose conduct is inevitably incident to the offense.20
On an exam stem the usual mistake is to treat the defendant's lack of the required status as a complete defense, reasoning that an outsider cannot be guilty of an offense only insiders can commit. Subsection (5) rejects that reasoning, but it does not dispense with the proof of complicity. The analysis runs in four steps:
Step four is the only place the exception operates, and it is the step students tend to skip in either direction. A stem that describes a protective or exempting purpose for the incapacity is pointing to the exception. A stem that mentions only that the offense is limited to officials or licensees is pointing to the default.
