Compulsory Joinder of Offenses

Compulsory Joinder of Offenses

Section 1.07(1), covered above, governs the end of a single trial. When the prosecutor has charged several offenses out of the same conduct, it limits how many convictions the court may enter. Subsection (2) governs an earlier question, which is whether the prosecutor may spread those offenses across several trials in the first place. The Code's general answer is no. A defendant shall not be subject to separate trials for multiple offenses based on the same conduct or arising from the same criminal episode, if the offenses were known to the appropriate prosecuting officer when the first trial began and are within the jurisdiction of a single court.¹ This is the rule of compulsory joinder, which means that offenses sharing a factual source must be brought together in one proceeding rather than tried in installments.

The text is phrased as a protection for the defendant, but it works as a duty on the prosecutor. The prosecutor decides what to charge and when, and a defendant has no power to gather the state's charges into a single case. The only way to give the defendant freedom from serial trials is therefore to require the prosecutor to bring every qualifying charge together at the outset. The sanction for failing to do so appears later, where § 1.09(1)(b) bars a later prosecution for an offense that should have been tried in the first prosecution.

The duty rests on three reasons that differ in strength. The most basic is the burden on the defendant. A Hawaii court reading its counterpart to the Code, HRS § 701-109(2), described the policy as sparing a defendant the expense and uncertainties of multiple trials based on essentially the same conduct or episode.² The subtler reason concerns incentive. If the state could try related offenses one at a time, a prosecutor who lost the first trial, or who thought the first sentence too light, would have every reason to select another charge from the same conduct and try again, now knowing the defense's strategy. The same court identified that danger, saying the rule is designed to prevent harassment through successive prosecutions where the state is dissatisfied with the punishment previously ordered or has previously failed to convict.³ Requiring all known charges to be tried together removes that opportunity at the source. The third reason is efficiency. Offenses that share time, place, and circumstances will usually draw on the same witnesses and the same evidence, so joinder spares both sides from presenting overlapping proof twice.⁴

Two conditions confine the duty to cases where the prosecutor can realistically comply. A prosecutor cannot join an offense the office does not know about, so knowledge is measured at the moment the first trial begins.⁵ Nor can a prosecutor join offenses that no single court has power to hear together. Section 1.07(3) then adds a release valve. When a defendant is charged with two or more offenses based on the same conduct or episode, the court, on application of either the prosecutor or the defendant, may order any charge tried separately if it is satisfied that justice so requires.⁶ The valve exists because joinder is a means to fairness, and a combined trial can itself become unfair to the defendant. The Hawaii court expressly left room for a defendant to assert a right to separate trials where joinder would be unjust and prejudicial.⁷

The two versions differ only in what the prosecutor knew at the start of the first trial, which shows that the duty attaches to what the office actually knew and not to what it might have discovered. On an exam stem the trap is confusing separate trials with separate convictions. Subsection (1) asks how many convictions may stand after a single trial, while subsection (2) asks whether more than one trial may be held. A prosecutor can satisfy subsection (2) by joining every charge and still face the limits of subsection (1) at judgment, so the two questions are asked separately. The next sections take the pieces of subsection (2) in order: what counts as the same conduct or the same criminal episode, the knowledge and single-court conditions, and the court's power under subsection (3) to order separate trials.

Same Conduct or Episode

The joinder duty in subsection (2) reaches two kinds of related offenses, and the statutory phrase separates them. Offenses based on the same conduct grow out of one act or one set of acts, so the link between the charges is visible on their face. Offenses arising from the same criminal episode may rest on different acts, and that extension is where disputes occur, because the words of subsection (2) do not say what makes an episode single.¹¹ A working test is therefore needed, and the one taught here comes from a state court and not from the Code itself. In State v. Aiu the Hawaii court read HRS § 701-109(2), the state's counterpart to the Code provision, and held that the singleness of a criminal episode turns on whether the alleged conduct was so closely related in time, place, and circumstances that a complete account of one charge cannot be related without referring to details of the other.¹² Because that test is one court's reading of a Code-derived statute, it is a persuasive gloss on the Code's phrase and not the Code's own definition.

The test takes this shape because it follows the reasons for compulsory joinder. When a full account of one charge requires the details of another, the two charges share their witnesses, their setting, and much of their evidence, so a second trial would retell most of the first. The Hawaii court reasoned that offenses occurring at the same time and place and under the same circumstances will probably involve overlapping witnesses and evidence, which makes joinder both fair to the defendant and efficient for the State.¹³ The test also has a practical advantage. It asks how the story of the charges would be told, a question a court can answer from the facts, and it avoids asking how each charge is labeled or what the defendant had in mind.

The same Hawaii decision supplies a situation where the claim of a single episode failed. The defendant there argued that his possession of a Mace canister belonged to the same episode as a schoolyard offense, pointing to the arresting officer's first noticing the canister at the schoolyard. The court applied the time, place, and circumstances test and rejected the contention that the offenses occurred concurrently.¹⁵ What separates this situation from the clerk example is how tightly the events are bound together in time, place, and circumstances. In the clerk example both acts fall within one minute at one counter, so each account carries the other. The defendant in Aiu relied on the place where an officer first noticed an object, and that reliance did not persuade the court that the offenses were concurrent.

A second question is whether a shared criminal purpose is enough to make one episode. The Hawaii court said it is not, and its reasoning rests on drafting history. Subsection (2), as first drafted, was considerably broader. The Code's Advisory Committee favored a formulation covering offenses based on a course of conduct having a common criminal purpose or plan, or involving repeated commission of the same kind of offense. The Council viewed that language, and the original wording, as too inclusive, and the final limit to the same conduct or the same criminal episode was designed to meet the Council's view.¹⁶ From that history the court inferred that a single episode is not determined solely by a defendant's singular criminal objective or common purpose or plan.¹⁷

The mechanism behind that choice is that a purpose test has no natural outer edge. A plan can be described at almost any level of generality, such as making money or settling a grudge, so nearly any two offenses by one person could be called parts of one plan. Joinder would then be forced on offenses separated by weeks and miles whose proof has nothing in common, and neither the fairness goal nor the efficiency goal would be served. The court also warned that mere allegations of a defendant's subjective intent are insufficient to require joinder of offenses that are otherwise unrelated.¹⁸ The court acknowledged that evidence of one crime may be admitted at the trial of another to show motive, intent, or a common scheme, but overlap in what may be admitted is a different matter from the closeness in time, place, and circumstances that the episode test requires.¹⁹

The two scenes differ in the facts that bind the offenses together. The clerk offenses are tied by closeness in time and place, and the pharmacy and jewelry store offenses are tied only by what the defendant wanted. On an exam stem the trap is treating a common plan as a single episode. A stem that describes several offenses as parts of one scheme invites the conclusion that joinder is compelled, but the scheme is one fact among others, and the test looks to time, place, and circumstances. The inquiry is easier when the charges rest on the same act, because the same-conduct language then applies and no episode analysis is needed.

Knowledge and Single Court

Subsection (2) does not command joinder of every offense that shares conduct or an episode. It confines the duty to cases where the prosecutor was in a position to comply, through two conditions that sit in the same clause of the text: the offenses must be known to the appropriate prosecuting officer at the time the first trial commences, and they must be within the jurisdiction of a single court.²² The conditions test different things. The first asks what the prosecutor's office knew, and the second asks what the court system permits, so a case can fail either one independently. Both matter because of the sanction behind the duty. The Hawaii statute that tracks the Code bars a later prosecution for any offense that the defendant should have been tried for in the first prosecution under the joinder section, unless the court ordered a separate trial.²³ A duty enforced by a permanent bar has to be one the prosecutor could actually perform, and each condition marks a point where performance would be impossible.

Begin with knowledge. The text measures it at one moment, the commencement of the first trial, and puts the question to the appropriate prosecuting officer, the official who controls the charging decision, so what a victim or bystander knew does not decide the matter.²⁴ The reason for the condition follows from the reason for the duty. Compulsory joinder exists to remove the temptation to split related charges, and that temptation arises only for a prosecutor who knows of the other charge and can choose to hold it back for a second trial. A prosecutor who has never heard of an offense can make no choice about it. Because the sanction for breaching the duty is a bar to later prosecution, stretching the duty to unknown offenses would turn an honest gap in information into permanent immunity for a crime the state never had a chance to bring. It would also deter nothing, since no prosecutor can be discouraged from withholding what the office does not know. The condition therefore separates a prosecutor's choice to split a case from an innocent failure to know of one, and it penalizes only the choice.

Two features of the wording keep the condition precise. The text asks whether the offense was known, which is a different question from whether it has been charged. A prosecutor who knows of a second offense when the first trial begins but would rather try it separately is exactly the prosecutor the rule targets, and the absence of a charging document for the second offense does not release the duty. The moment of measurement matters as well. Knowledge is fixed at the commencement of the first trial, so an offense the office learns of in the middle of that trial, or afterward, falls outside the duty, and the text asks what the office knew rather than what a more energetic investigation might have turned up.²⁵

The second condition concerns the courts and not the prosecutor. Joinder means trying every qualifying offense in one proceeding, and a single proceeding is possible only if some one court has power to hear all of them.²⁸ Where no tribunal has that power, even a prosecutor who knows of every offense and wants to join them cannot do so, and a bar imposed for failing to do the impossible would punish no wrongdoing at all. The condition therefore asks about jurisdiction in the legal sense, meaning whether a court has authority over the offenses, and the next question is how a court's authority is measured.

The answer turns on what a court is able to hear, and the place where such offenses are usually filed does not decide it. In State v. Aiu the Hawaii Supreme Court noted that misdemeanors are normally tried in the district court unless the trial is by jury, a fact that might suggest the misdemeanor and felony charges before it belonged in different courts. The court explained that all of the charged offenses could nevertheless have been tried together in the circuit court, because that court had jurisdiction over every criminal offense cognizable under state law, no statute or rule kept it from hearing misdemeanors joined with a felony, and the procedural rules then in force permitted such joinder.²⁹ The Hawaii legislature drew on the Code's drafts and commentary when it enacted these provisions, and the court read them consistently with the Code's structure, so the reasoning shows how the Code's single-court language operates, though it remains one state's reading.³⁰

The reason to measure by power rather than by routine is an incentive reason. The prosecutor decides where each charge is filed. If the everyday assignment of misdemeanors to a lower court were enough to defeat the condition, a prosecutor could file the misdemeanor there and the felony in the higher court, point to the two courtrooms, and obtain the separate trials the duty is meant to forbid. Measuring by power closes that route, so a court that can lawfully hear all the charges satisfies the condition even when the state's usual practice would have divided them. The condition fails only when the structure of the courts leaves no single tribunal able to take every offense.

Joinder therefore cannot reach across sovereigns, because each government's courts hear only its own offenses. How a prosecution by one government affects a later prosecution by another is a separate question, and the later chapter on prosecution in another jurisdiction takes it up.

On an exam stem the trap is assuming that different usual courts mean no single court. A stem that mentions a misdemeanor docket and a felony docket does not end the inquiry. The question is whether one court has power to hear every offense, and the facts must supply a reason it does not, such as a charge reserved to another sovereign's courts. The same caution applies to knowledge: a stem reporting that no charge had yet been filed for the second offense says nothing about whether the prosecutor knew of it. Failing either condition ends only the joinder duty and the bar that depends on it. The Hawaii counterpart to the Code's separate bar for an offense based on the same conduct is framed on different terms and contains neither a knowledge condition nor a single-court condition, so whether a later prosecution is barred on that ground is a question for the same-conduct rule that comes later.³²

Court-Ordered Separate Trials

Subsection (2) forbids separate trials for offenses that share conduct or an episode, but it makes that command subject to subsection (3).³⁴ Subsection (3) supplies the release valve. When a defendant is charged with two or more offenses based on the same conduct or arising from the same criminal episode, the court, on application of the prosecuting attorney or of the defendant, may order any such charge to be tried separately if it is satisfied that justice so requires.³⁵ The text allocates three separate decisions. Either side may start the process by applying, the court alone decides, and the standard for deciding is justice, so the court looks at whether a joint trial would be fair rather than at which side would like a second trial.

The exception exists because the duty to join and the fairness it serves can pull apart. Joinder protects the defendant from the expense and uncertainty of repeated trials, and it spares both sides from presenting the same evidence twice.³⁶ Yet a joint trial is sometimes the unfair option. Evidence that is proper on one charge may sway a jury unfairly on another, and a large number of charges and witnesses may swell a trial past what jurors can sort out. The Hawaii court that adopted the closeness-in-time, place, and circumstances test took care to say that its holding does not preclude a defendant from asserting a right to separate trials where joinder of the offenses would be unjust and prejudicial.³⁷ Either party may apply because each sees a different part of the problem: the defendant is positioned to spot prejudice to the defense, and the prosecutor is positioned to spot a presentation that would confuse the jury.

Placing the decision with the court does subtler work. The duty of compulsory joinder exists to remove the temptation of a prosecutor who knows of related charges and could hold one back for a second trial. If that same prosecutor could declare a charge separate on the prosecutor's own say-so, the duty would become a suggestion, because anyone wanting a second trial would only need to announce that the charge was being tried apart. Requiring an application and a judicial finding puts a decision-maker with no stake in the outcome between the prosecutor and the second trial. The word may also leaves the ruling to the court's discretion, so an application that fails to persuade produces no severance and the joint trial goes forward. The order itself becomes the record that the split was approved, and that record matters later: the bar in § 1.09(1)(b) for offenses that should have been joined carves out the case in which the court ordered a separate trial, a point the chapter returns to when it reaches former prosecution for a different offense.

The two scenes share the same charges and the same worry about prejudice. The fact that moved the answer is whether a court examined that worry and ordered separation. On an exam stem the trap is treating the prosecutor's own decision to split the case as a severance. A stem that says the prosecutor chose to try the offenses one at a time, or that the defendant did not object to the order of trials, describes no order, and subsection (3) is satisfied only by a court's finding that justice requires separation. The same stem may instead describe an application that the court granted, and then the later trial is authorized and the joinder duty gives way.
