The Oklahoma Sentencing Modernization Act of 2024 (OSMA24) classifies virtually every crime defined in Oklahoma law, including hundreds of arcane, obsolete, and rarely or never prosecuted crimes, within a sweeping system of sentencing reform. But the sprawling, 107-page original bill and its amendatory cohort HB 2104 (712 pages of amendments adding classification language to every known criminal offense) are unwieldy as a practical guide to their own requirements, and some of the penalty provisions are crafted from complex cross-references to other sections.
The OSMA24 creates 17 new sections of law in Title 21, Oklahoma Statutes, to be codified as Sections 20A through 20P. The new system classifies all felonies by severity “and other factors.” Class Y contains a single crime, first degree murder, in all of its statutory forms including malice aforethought, felony murder, child abuse murder, law enforcement officer murders, drug distribution murders, and so on.
Section 20C defines Class A1 felonies (~15 crimes); Section 20D defines Class A2 felonies (~21 crimes); Section 20E defines Class A3 felonies (~21 crimes); Section 20F defines Class B1 felonies (~45 crimes); Section 20G defines Class B1 felonies (~22 crimes); Section 20H defines Class B3 felonies (~47 crimes); Section 20I defines Class B4 felonies (~75 crimes); Section 20J defines Class B5 felonies (~36 crimes); Section 20K defines Class B6 felonies (~14 crimes); Section 20L defines Class C1 felonies (~24 crimes); Section 20M defines Class C2 felonies (~158 crimes); Section 20N defines Class D1 felonies (~351 crimes); Section 20O defines Class D2 felonies (~21 crimes); Section 20P defines Class D3 felonies (~217 crimes).
This site’s treatment of the OSMA24 dispenses with the many offenses rarely prosecuted–but a complete index is included–and focuses instead on those commonly prosecuted crimes already studied in this book, hopefully in a way that allows quick reference by counsel and the courts. For historical perspective, I have retained the pre-OSMA24 sentencing ranges for crimes included in prior editions of the book.
Each crime considered in this book now bears its OSMA24 Classification and a hyperlink to a quick reference page containing unenhanced and enhanced ranges for that specific offense class. Remember that Classes Y, A1 through A3, and B1 through B6 felonies will continue to be punishable by currently existing penalties and fines, as are all misdemeanors. After OSMA24’s effective date of January 1, 2026, Classes C1-C3 and D1-D3 felonies, with some exceptions, will be punishable as set forth here.
Good luck!
