Grade as the Deciding Variable
The two rules taught so far are halves of one comparison, and this section runs them together as a single decision sequence. The sequence has two variables. The first is whether the offenses arose from the same act or transaction, a filter that removes separate incidents from the doctrine, because offenses that spring from different conduct duplicate nothing. The second is the grade of each offense, meaning its classification as a felony or a misdemeanor, and it is reached only when the first answer is yes.1 Once both answers are in hand, the outcome follows without any further inquiry into how the offenses are defined.
The second step is where the analysis turns, and it is quick by design. A court applying the common-law rule reads the classification each offense already carries and compares the two classifications; it does not line up the elements of one crime against the elements of another. That makes the test easy to run under time pressure, since an exam stem usually supplies both facts outright: whether the episode was single, and which offense is the felony. The same feature makes the test crude, because a label is only a rough stand-in for how much of one offense is contained in another. The element-based lesser-included analysis taught later in this chapter asks a different question, and it should be kept apart from the grade comparison here.
A paired set of facts shows how the variable works, with the first question answered identically in both versions.
Both versions pass the same-transaction filter, so the grade of the second offense is the one variable that moved the result. The outcome can feel backwards, because the harsher conduct produces two convictions and the milder conduct produces one. The explanation lies in what merger removes. A robbery conviction already condemns a slap that formed part of the robbery, so a separate battery conviction would count the same wrong twice. A second felony is not a smaller piece of the first. Two felonies stand as equals, so neither merges and each keeps its own conviction.4
Two errors recur when students run this sequence. Students lose this issue when they merge a felony component into a larger felony because it looks like a smaller piece of the episode, since the misdemeanor-into-felony rule needs a misdemeanor and a felony that is part of another felony's conduct still stands as a separate conviction.5 The opposite error is to notice a felony and a misdemeanor, see that the grades differ, and merge without first checking the transaction. A slap delivered days before the car-taking is a separate episode, so the first step ends the analysis whatever the grades are.
Because the test reads classification rather than definition, it ignores how technical or how different the definitions of two offenses are. Skinner v. Oklahoma, which concerned a sterilization statute and not merger, records that Oklahoma punished larceny and embezzlement of more than twenty dollars as felonies carrying the same fines and imprisonment, even though the line between them turned on when the felonious intent arose.6 Offenses can therefore differ sharply in definition and still share a grade, and for common-law merger it is the shared grade that would count. Outside merger, the felony and misdemeanor label can matter for reasons that depend on a statute's own words: a dissenting Board member in In re Small, an immigration case, reasoned that Congress said so expressly whenever it meant misdemeanors to fall within the aggravated felony category.7 The common-law merger rule needs no such instruction, because it is itself written in terms of grade.
