Most jurisdictions have a number or letter classification system to describe misdemeanors from the most serious to the least serious, but a misdemeanor falling outside of a jurisdiction’s normal classification system is commonly called an unclassified misdemeanor.
An unclassified misdemeanor may refer to the least serious infractions resulting in criminal punishment, or it may refer to a misdemeanor without a specified punishment.
Misdemeanors are generally distinguishable from felonies through the punishments associated with each. Misdemeanors are less serious and typically come with a maximum penalty of less than a year's imprisonment. Felonies are more serious and typically come with a maximum penalty of one year or more of imprisonment.
Misdemeanors are commonly broken down by seriousness with classifications like Class A, Class B, Class C; or Class 1, Class 2, Class 3. These classifications are usually based on the punishments associated with the crime.
Many jurisdictions have unclassified misdemeanors that come with no specified punishment.
