A lesser related offense is a criminal offense that is similar to another more serious offense; however, it is not quite the same and it is not quite as severe. Lesser related offenses, in general, have less severe consequences than their more severe counterparts do.
There are many different offenses that can qualify as lesser related offenses.
Often, lesser related offenses are classified that way because they do not meet all of the elements of a more severe offense. For example, a person who robs another person using only intimidation and their hands will be charged with robbery and not armed robbery. However, if a person uses a gun to rob another person, then they will be charged with armed robbery. In this case, robbery would be the lesser related offense to armed robbery.
