The Code Commissioner is authorized to add all crimes and offenses enacted by the General Assembly to §§ 16-1-90 and 16-1-100 of the 1976 Code. However, the crimes and offenses must be added to the appropriate category as established by § 16-1-20(A). If the term of imprisonment for a crime or offense does not fit into one of the six established felony categories or one of the three established misdemeanor categories, it must be placed on the list of exempt offenses contained in § 16-1-10(D). The purpose of this provision is to allow the Code Commissioner to place crimes and offenses in the appropriate category as established by the General Assembly without requiring each act which affects crimes and offenses to specifically reference § 16-1-90 or 16-1-100. The Code Commissioner is prohibited from changing the designation by the General Assembly of any crime or offense from felony to misdemeanor or from misdemeanor to felony and is likewise prohibited from changing the number of years of any sentence set by the General Assembly.
