Sentencing Guidelines Manual
The District of Columbia Sentencing and Criminal Code Revision Commission published the 2010 edition of the Voluntary Sentencing Guidelines Manual, which replaces the 2008 Practice Manual. The 2010 Voluntary Sentencing Guidelines Manual should be used for all pleas or verdicts on and after May 3, 2010, unless the parties agree to use the version in effect at the time of sentencing. The substantive changes to this edition of the Voluntary Sentencing Guidelines Manual are listed in Appendix J.
