Merger of Offenses Law and Legal Definition

Merger of offenses refers to the common law doctrine that if a misdemeanor is an ingredient of a felony, the misdemeanor is an integral part of the felony and prosecution should be only for the felony.

It also refers to embracing of one offense, necessarily involved in another, in the latter offense, for the purposes of determining the penalty upon conviction on a plea of guilty. For example, robbery involving both assault and larceny.
