No Merger Among Equal Offenses
The merger rule for a misdemeanor and a felony runs in one direction: the lesser grade disappears into the greater. That direction explains the companion rule for offenses that share a grade. At common law, offenses of the same degree did not merge into one another, so separate crimes of the same grade remained distinct and each could independently support its own conviction.1 A parallel statement ties the rule to the single-transaction setting. When the same act, or a series of acts forming a single transaction, satisfied the elements of several felonies (or of several misdemeanors), none of those offenses merged into the others, and the existence of one neither extinguished nor absorbed the others.2 This is the negative image of the rule in the previous section. The first common-law question, whether the offenses arose from the same act or transaction, may be answered yes, and still no merger follows, because the second question, the comparison of grades, finds no hierarchy.
The reason follows from how merger works. Merger operates by absorption: a conviction for the greater offense already condemns every piece of conduct that went into it, so a separate conviction for a lesser component would count the same wrong twice. Absorption needs a greater and a lesser. Two felonies, or two misdemeanors, stand at the same level, so neither can be treated as a component swallowed by the other. Each is also a distinct violation with its own elements and its own protected interest, which means a conviction for one does not condemn what the other punishes. Folding one into the other would let a defendant who committed several equal-grade crimes in a single transaction answer for only one of them, and merger was never meant to produce that result, since it removes only duplicated condemnation.
A sentencing record shows what stacked convictions look like in practice. In Coker v. Georgia, a footnote records that Coker received separate sentences for kidnaping, rape, aggravated assault, and a second rape committed against one victim, and for the rape and the murder of another victim.3 Coker was not a merger decision, and the footnote is useful only as a picture of the result: several serious offenses arising from one course of conduct, each carrying its own conviction and its own sentence instead of collapsing into the most serious one. The same holds on both sides of the felony and misdemeanor line, so long as the grades match.
The comparison with the first rule shows which fact does the work. Only the grade of the second offense needs to change to bring the earlier rule back into play.
Students lose this issue when they stop the analysis after finding a single transaction. A shared transaction opens the inquiry but does not decide it, because the grade comparison determines whether anything can be absorbed. If the grades differ, the lesser offense merges into the greater. If the grades match, nothing merges, and each offense stands on its own. Modern lesser-included-offense analysis, taught later in this chapter, can still limit stacked convictions even among offenses of the same grade, but that limit comes from a different doctrine and leaves the common-law rule stated here unchanged.
