Merger Under Modern Law
The two common-law rules reached their results by comparing grade: a misdemeanor merged into a felony, and offenses of equal grade did not merge. American law today has largely moved away from that approach. The general modern rule is that offenses do not merge, so a defendant whose conduct satisfies the elements of several offenses may be convicted of each, subject to a short list of exceptions taught in the rest of this section. The shift follows from the weakness already visible in the grade test. A felony or misdemeanor label is a rough proxy for how much of one offense is contained in another, and a rule built on labels says nothing about whether the two offenses punish the same wrong.
The exceptions that survive share one feature. In each, one offense is wholly contained in another or is a step toward it, so a conviction for both would punish the same wrong twice. Where the offenses are genuinely distinct wrongs, each may stand, and the limits come from double jeopardy and from legislative design instead of from a grade-based common-law rule. That is why the modern exceptions are defined by the relationship between the offenses, and none turns on whether either one is a felony.
The Maryland decision in State v. Hawkins shows the default at work. Hawkins was convicted both of felony murder and of being an accessory after the fact, meaning one who helps a felon after the crime, in the same killing, and the court abrogated the old common-law element that an accessory after the fact could not also be a principal in the substantive felony, so that both verdicts could stand.1 The intermediate appellate court had already concluded that the two offenses simply do not merge, and the high court observed that its required evidence test, the measure of merger it applied, was not met, because each offense demands proof that the other does not.2 The court nonetheless held that no separate sentence could be imposed on the accessory conviction, and it said that this prohibition was not a matter of merger under that test.3 The case therefore shows both halves of the modern picture: distinct offenses ordinarily remain separately convictable, and limits on stacking punishment can arise outside the merger label.
The remaining sections take the exceptions and boundaries one at a time. The first is the merger of solicitation or attempt into the completed crime, followed by the contrast case of conspiracy, which stands apart from the offense it aims at. The Model Penal Code limit on multiple inchoate-crime convictions comes next, then the most important merger-like rule, the merger of lesser included offenses into greater ones, and then the developing rules against multiple convictions for parts of one criminal transaction. The last section gives a boundary test that separates offenses from sentencing factors, and the first section below begins with solicitation and attempt.
Solicitation and Attempt
The first surviving exception to the modern no-merger default covers the two earliest steps toward a crime: asking someone else to commit it, and trying to commit it oneself. Solicitation means urging, requesting, or encouraging another person to commit a crime, and it is punishable as an offense of its own where the jurisdiction makes it one. Attempt means acting with the intent to commit a crime and taking steps toward it that go beyond mere preparation, but stopping short of completion. Offenses of this kind are called inchoate, meaning they are incomplete steps toward a target crime rather than the target crime itself. The merger rule for them has two parts. A defendant who solicited another person to commit a crime cannot be convicted of both the solicitation and the completed crime when the person solicited carries it out, and a defendant who attempted a crime and then completed it cannot be convicted of both the attempt and the completed crime.
This exception is the old misdemeanor-into-felony rule from the first section of this chapter, carried into modern law. At common law, a misdemeanor that formed part of the conduct constituting a felony merged into the felony, so a defendant whose misdemeanor and felony arose from the same act or transaction could not be convicted of both.5 Attempt was a misdemeanor at common law, which made an attempt that ripened into the completed felony a clean instance of that rule: the felony conviction stood and the attempt dropped out. The modern rule keeps that result and rests it on a different footing. It asks whether the inchoate offense was a step toward the very crime that was completed. Grade drops out of the question, so a completed misdemeanor absorbs an attempt or solicitation aimed at it just as a completed felony does.
The reason for the rule lies in how an inchoate offense is defined. The law punishes the solicitor and the attempter before any harm occurs because pursuing a criminal objective is dangerous in itself, and once the objective is reached, the completed crime condemns everything the earlier step contributed. A defendant who asked another person to commit a robbery and then watched the robbery happen has one criminal objective, and a conviction for the robbery already reaches the whole of it. Adding a solicitation conviction would count that objective twice, once as the plan and once as the accomplished fact. The rule also costs public protection nothing, because the defendant remains answerable for the completed crime, which carries the heavier penalty, and the rule removes only the duplicate.
The merger applies only once the target crime is actually completed. Merger works by absorption, and absorption needs a completed offense to do the absorbing. A solicitation that produces no crime, or an attempt that fails, has nothing to fold into, so the inchoate conviction is the only one available and it stands on its own. Dropping it would also leave a defendant who pursued a criminal objective unpunished for the pursuit, which is the gap the inchoate offenses exist to close. The completed crime must also be the one the solicitation or attempt aimed at, since an unrelated completed offense is not the end point of that objective and absorbs nothing.
On an exam stem, the deciding fact is usually a single sentence about what happened after the solicitation or attempt. Students lose this issue when they merge the inchoate offense without confirming that the target crime was actually completed. The opposite error is to let a solicitation or attempt conviction stand beside the completed crime because the elements of the two offenses differ. Differing elements do not control here, since the inchoate offense is a step toward the completed one and the two count a single objective. The same answer should also not be carried over to conspiracy, which is inchoate as well but is treated differently, as the next section shows.
Conspiracy Stands Apart
Conspiracy is the third of the familiar inchoate offenses, and the merger rule that governs the other two does not reach it. A conspiracy is an agreement between two or more people to commit a crime, and that agreement is what the law punishes. Solicitation and attempt, as the previous section showed, drop out once the target crime is completed. Conspiracy stays in: a defendant whose agreement ripened into the completed offense may be convicted of the conspiracy and of the completed crime, so robbery and conspiracy to commit robbery can each support a conviction.7
The difference follows from what each offense punishes. A solicitation or an attempt is a step along a path that one actor is walking toward the completed crime. When the path reaches its end, the completed offense condemns everything the step contributed, and a second conviction would count a single objective twice.8 Conspiracy punishes something else: the agreement itself, which is finished at the moment the participants commit themselves to the plan and so exists before anyone carries out the substantive offense. Because the agreement is complete on its own terms, it is not a smaller piece of the completed crime, and the robbery does not absorb it. The robbery conviction answers for the taking, and the conspiracy conviction answers for the agreement to take, which is a different wrong with its own place in time. Two convictions therefore do not count one wrong twice.
That reasoning also explains why the question that controlled the previous section, whether the target crime was actually completed, has no bearing here. An agreement is punishable whether or not the crime follows, and when the crime does follow, the agreement keeps its separate conviction. A single fact pattern can show both treatments side by side.
The second scene isolates the contrast. Two inchoate offenses aimed at the same completed robbery receive opposite treatment, because the attempt is a stage of the robbery and the agreement is a wrong of its own.
On an exam stem, the pull is to file every inchoate offense under one merger rule. Students lose this issue when they carry the attempt-and-solicitation answer over to conspiracy, merging the agreement into the robbery because the agreement led to it. The opposite instinct, withholding the conspiracy conviction because the offenses overlap in what they aim at, makes the same mistake from the other direction, since overlap in objective is the very feature that causes attempt and solicitation to merge and has no such effect on conspiracy. One further limit applies when a defendant faces more than one inchoate conviction aimed at the same target crime, and the next section takes it up.
Multiple Inchoate Crimes
The previous section showed that conspiracy keeps its own conviction beside the completed crime. A different problem arises when no crime is completed and the prosecution charges several inchoate offenses (solicitation, attempt, and conspiracy) that all point at the same target. The Model Penal Code limits this: a defendant may not be convicted of more than one inchoate offense for conduct designed to culminate in the same crime (Model Penal Code § 5.05(3)). The standard example is a conspiracy to commit burglary followed by an attempt at that burglary. The agreement and the attempt are different offenses with different elements, yet both aim at one burglary, so only one conviction can stand. This is a Model Penal Code rule rather than a universal common-law one, and a jurisdiction that has not adopted it may treat the two charges differently.
The common-law grade comparison from earlier in this chapter would not produce this result. Offenses of the same grade did not merge into one another at common law, so a grade test leaves each of them free to support a conviction.10 The Model Penal Code limit asks a different question. It looks at what the conduct was designed to accomplish and whether several inchoate offenses share that one objective.
The reason follows from what inchoate offenses punish. The law punishes the agreement and the attempt before any harm occurs because pursuing a criminal objective is dangerous in itself. When two or three inchoate offenses are aimed at the same crime, they are successive stages of one pursuit, and a conviction for each would count that pursuit more than once. This differs from the conspiracy that survives beside a completed robbery, where the robbery is a separate, realized wrong. Here nothing was completed, so a second inchoate conviction adds only a second label for the same effort, and the limit removes the duplicate.
On an exam stem, the deciding fact is whether the inchoate offenses share a target. Students lose this issue by stacking convictions for conspiracy and attempt when the facts show one intended crime, or by applying the limit to offenses aimed at different crimes. The rule also does not replace the earlier ones: once a target crime is actually completed, the rules on solicitation, attempt, and conspiracy from the previous two sections govern. The next section takes up the most widely applied merger-like rule, which concerns offenses that are wholly contained in other offenses.
Lesser Included Offenses
The previous section ended with inchoate offenses aimed at one target crime. The rule taught here covers a different relationship, in which one offense sits wholly inside another, and it is the most widely applied of the merger-like rules in modern law. A lesser included offense is an offense whose elements are all elements of a greater offense, so the greater offense cannot be proved without proving the lesser one along the way.12 The lesser offense is said to merge into the greater: a defendant placed in jeopardy for either offense may not later be retried for the other, and may not be convicted of both. The label merger is incidental here, because the constitutional bar on double jeopardy requires the result whatever name is attached to it.
This rule differs from the comparison taught earlier in this chapter. Common-law merger looked at grade: a misdemeanor merged into a felony arising from the same act or transaction, and offenses of equal grade did not merge into one another.13 The lesser-included rule compares elements instead, setting the definition of one offense against the definition of the other. Grade and the label the legislature gave the crime drop out of that comparison, and two charges that rest on a single act can still stand apart if each requires proof the other does not.
The rule rests on what elements accomplish at a trial. When every element of the lesser offense is also an element of the greater, a guilty verdict on the greater necessarily finds each fact the lesser requires. A second conviction for the lesser would then punish the defendant again for facts already found, and a second prosecution would make the defendant answer again for proof the state has already offered. The double jeopardy bar forbids exactly that, which gives the rule constitutional force beyond any common-law preference. The converse follows from the same reasoning: when each offense requires proof of a fact the other does not, neither is contained in the other, and a conviction on each answers for a different proved fact, so both may stand.
The comparison is an old one. The dissent in Grady v. Corbin, surveying English and early American practice, recounts that under the older pleading rules an acquittal on a charge made of fewer circumstances, A and B, also acquitted the defendant of a narrower charge made of A, B, and C, because a person innocent of the smaller charge cannot be guilty of the larger. Charges made of A, B, C and of A, D, E shared only a common circumstance, so an acquittal on one did not reach the other.14 The same dissent treats an English case's statement that evidence of one offense would not support an indictment for the other as the equivalent of the later formula that "each provision requires proof of a fact which the other does not."15
The two possession scenes differ in a single fact, the identity of the second charge, and that fact moves the answer because it changes what each offense requires. In the first scene the lesser offense demands nothing the greater lacks. In the second, each offense demands something the other lacks, so shared conduct by itself does not trigger the bar.
In Brown v. Ohio a defendant was convicted of operating a vehicle without the owner's consent and was then charged with stealing the same vehicle in the same incident. Operating without consent is a lesser included offense of theft, so the first conviction barred the theft prosecution. Brown teaches two things relevant here. The order of prosecution does not matter, since jeopardy on the lesser offense bars the greater just as jeopardy on the greater bars the lesser. And a prosecutor cannot avoid the rule by splitting an included offense and its greater offense across two separate trials. The full test for what counts as the same offense belongs to the double jeopardy readings, and Brown is used here only for those two points.
A greater offense can also contain another crime because the statute defines it that way. A felony-murder statute makes a killing in the course of a felony murder without separate proof of malice, so the felony becomes a fact the prosecution must prove to win the murder conviction. The Georgia statute reproduced in the footnotes to Gregg v. Georgia provides that a person commits murder when a death is caused in the commission of a felony, "irrespective of malice."16 In State v. Sims the West Virginia court read its statute, which reaches deaths in the commission of or attempt to commit arson, rape, robbery, or burglary, to require no malice, premeditation, or intent to kill, in keeping with the common-law rule.17 A dissent in People v. Howard describes the doctrine in the same terms for a death caused during an inherently dangerous felony, as one that absolves the prosecution from proving malice.18
Because the felony stands in for malice, it is an element of the murder, and the underlying felony is therefore a lesser included offense of the felony murder. Harris v. Oklahoma shows the consequence. The defendant was convicted of felony murder because an accomplice killed a clerk during an armed robbery, and the state then prosecuted the defendant for the armed robbery itself. The robbery was the underlying felony, so it was included in the felony murder and the later prosecution was barred.
A greater offense can contain lesser ones because it is a compound of them. A concurring opinion in People v. Anderson notes that the common law defined robbery as larceny from the person by open and violent assault, and it reasons that if robbery combines theft and assault, proof of a robbery requires proof of every element of each.19 On that view, theft of the property taken in the robbery is a lesser included offense of the robbery, and the two cannot both support convictions. The label lesser included also appears in a separate setting, jury instructions on whether a jury may consider a lesser offense, as in the Florida proceedings recounted in Spaziano v. Florida, where a claim under Beck v. Alabama on that subject was found inapposite.20 That dispute concerns what the jury may consider and has no bearing on whether two convictions can coexist.
On an exam stem, the pull is to stop at the shared facts. Two charges can rest on one act, as the possession charges do, and both still stand when each requires an element the other lacks. The question that decides the issue is whether every element of one offense is an element of the other. Students also err by importing the grade comparison from common-law merger, which asks about misdemeanors and felonies and has no role in this element comparison.
Same-Transaction Limits
The lesser-included rule from the previous section compares the definitions of two offenses and asks whether one sits wholly inside the other. A separate group of limits, still developing, asks a different question: whether the offenses were parts of one criminal transaction. At common law that question was only an entry condition, since a misdemeanor merged into a felony only when both arose from the same act or transaction and the two differed in grade.22 The modern limits make the transaction the whole test and leave grade out of it. Some legislatures impose the limit by statute, and some courts reach a similar result by adopting a merger or double jeopardy rule of their own. Because the reach of these limits varies from one jurisdiction to the next, this section describes the trend and the counterpoint to it without stating a single rule that every jurisdiction follows.
Minnesota's statute is a useful model of the statutory route. Section 609.035, subdivision 1, prohibits the imposition of multiple sentences for offenses committed as part of a single behavioral incident.23 The statute works at sentencing, which shows that a same-transaction limit can attach to the punishment a defendant receives rather than to the number of verdicts returned. It also carries listed exceptions. A defendant who commits a felon-in-possession-of-a-firearm offense, fleeing a police officer, criminal sexual conduct, or arson may be convicted and sentenced for other offenses arising from the same behavioral incident, and separate charging statutes for methamphetamine-related crimes involving children or vulnerable adults, burglary, and kidnapping likewise permit sentences for multiple offenses from one incident.24
The reasons for the limit and for its exceptions can both be read off the structure of the statute. A single episode can usually be described under several criminal statutes, so a prosecutor who charges every description can multiply convictions and punishment without any increase in the wrong actually done. Tying the cap to the transaction holds the total near the level of what happened. Because the cap is the legislature's own creation, the legislature can also decide where it does not apply, and the list of exceptions shows it doing so for offenses it judged to deserve punishment of their own.
Courts have reached a similar place without a statute. In State v. Hawkins the jury convicted the defendant of felony murder and of being an accessory after the fact in the same murder.25 The common-law element that an accessory after the fact may not also be a principal in the felony would have made those two verdicts inconsistent, so the Maryland court abrogated that element and allowed both convictions to stand.26 That change exposed a principal to a second conviction for one course of crime, and the court answered by barring a separate sentence on the accessory conviction: only one judgment may be entered, on the substantive felony as the greater offense.27 The court said this bar is not merger under the required-evidence test, which compares the proof each offense demands, because the two offenses do not merge under that test. The bar rests instead on the same rationale that forbids separate sentences for merged offenses, a matter of public policy and fundamental fairness.28 The accessory conviction is not erased. If the murder judgment is later reversed for insufficient evidence, the defendant still stands convicted as an accessory and may be sentenced on that charge, up to the five-year maximum.29
The element comparison from the last section would have left both Hawkins convictions and both sentences in place. The same-transaction idea reaches that overlap because it asks about fairness to a defendant who committed one course of crime, and it does not depend on one offense being contained in the other.
The counterpoint is that these limits yield to a clear legislative choice. A legislature defines offenses and fixes their punishments, so when it clearly authorizes separate punishments for a single act, imposing them does not violate the double jeopardy bar.30 The exceptions in the Minnesota statute are the working form of that authority. The idea that one act does not automatically make one offense is also old. The dissent in Grady v. Corbin recounts that in State v. Sonnerkalb an early South Carolina court allowed a second prosecution based on the same sale, reasoning that one physical act can be two offenses when each requires proof of a fact the other does not.31
The two scenes differ in one fact, whether the legislature addressed cumulative punishment, and that fact decides the outcome because the limit and its exceptions come from the same source. A same-transaction bar caps punishment at what one episode deserves, and a specific authorization marks the offenses the legislature chose to punish separately. Since the doctrine is still developing, an answer has to identify which source of law governs before it counts convictions.
On an exam stem, students lose this issue when they announce a uniform rule against multiple convictions for one transaction, because the doctrine is statutory in some places, judge-made in others, and absent in the rest. The opposite error treats one act as one offense in every case, which ignores both the element comparison and the legislature's power to authorize cumulative punishment. The next section supplies a boundary test for the whole topic, separating an offense that is compared with other offenses from a fact that only limits a sentencing court's discretion.
Offense Versus Sentencing Factor
Every rule in this chapter compares offenses. Common-law merger asked whether a misdemeanor had merged into a felony arising from the same act or transaction.33 The lesser-included rule compares the elements of two crimes, and the same-transaction limits count convictions that rest on one episode. Each inquiry therefore has a prerequisite that is easy to overlook: two offenses must be on the table. A sentencing factor is a fact the court weighs after conviction to choose a penalty within a range the conviction already authorizes, and such a fact is not an offense at all. Merger and double jeopardy exist to keep a defendant from being convicted or punished twice for the same offense. A sentencing factor adds no second conviction to the first, so there is no duplicate for either doctrine to remove, and the comparison has nothing to operate on.
McMillan v. Pennsylvania shows a fact on the sentencing side of that line. Pennsylvania's statute raised the minimum sentence to five years for a defendant convicted of one of several listed felonies, among them third-degree murder, robbery, and aggravated assault, when the sentencing judge found that the defendant had visibly possessed a firearm. The provision became applicable only after the defendant had been duly convicted of the crime for which punishment was to be imposed, and the listed felonies already carried maximums of twenty years for first-degree felonies and ten years for second-degree felonies.34 The Court found that the provision neither altered the maximum penalty for the crime committed nor created a separate offense calling for a separate penalty, because it operated solely to limit the sentencing court's discretion within the range already available.35 The firearm finding sits inside one conviction and moves only the floor of an existing range. That leaves a single offense, so there is nothing for merger or the double jeopardy bar to act on.
The contrasting kind of statute attaches greater or additional punishment to the added fact. McMillan itself pointed to 18 U.S.C. § 2113(d), which provides separate and greater punishment for bank robberies accomplished through the use of a dangerous weapon or device, as the kind of provision under which a claim that the fact is really an element would have more appeal.36 What separates the two statutes is what the added fact does to the defendant's exposure. In Pennsylvania the firearm finding left the ceiling where it was. Under § 2113(d) the weapon exposes the defendant to a separate and greater penalty, which is how a legislature ordinarily marks off a graded offense. Once a statute makes the weapon the feature that distinguishes the graver crime, the weapon is an element of that crime, and if the graver crime contains every element of the plain robbery, the plain robbery becomes a candidate lesser included offense under the analysis from the previous section.
The two statutes differ in one respect, whether the added fact defines a crime with its own penalty, and that single fact decides whether there is anything to compare. Some statutes sit close enough to the line that the classification itself is contested. Under 8 U.S.C. § 1326, a deported alien who reenters faces a two-year maximum, and subsection (b)(2) raises the maximum to twenty years if the alien had been convicted of an aggravated felony.37 In Almendarez-Torres v. United States, as Justice Scalia's dissent describes it, the Court held that subsection (b)(2) is a sentencing enhancement for the offense in subsection (a) and not a separate offense.38 The dissent would have read (b)(2) as a separate offense that includes the violation in subsection (a) and adds the element of a prior aggravated felony conviction.39 That is the dissent's view and not the Court's holding, but it shows the threshold from both directions. If (b)(2) is an offense, subsection (a) is its lesser included offense and the earlier rules apply, and if it is an enhancement, there is one offense and they do not. The dissent also rejects the idea that a fact becomes a sentencing factor merely because judges tend to sentence higher when it is present, since judges would also sentence higher for a crime committed with a firearm or in the course of another felony, yet armed robbery and felony murder are separate crimes.40 The constitutional question the case raises, whether such a fact must be charged and proved to a jury, belongs elsewhere. Here the case matters only because it shows that classification comes first and depends on how the legislature wrote the statute.
Stems on this point usually describe a statute that adds a firearm, a prior conviction, or a similar fact and then ask whether the defendant can be convicted of both. Students lose the issue when they run an element comparison on a fact that only moves the sentencing range, because the comparison presupposes two offenses and a sentencing factor supplies only one. The opposite error is to wave off any added fact as mere sentencing when the statute attaches a separate and greater penalty to it. A statute of that kind resembles the graded offense in § 2113(d), and the comparison rules then apply.
