2009 FEDERAL SENTENCING GUIDELINES MANUAL
CHAPTER ONE - PART B - GENERAL APPLICATION PRINCIPLES
§1B1.7. Significance of Commentary
The Commentary that accompanies the guideline sections may serve a number of purposes. First, it may interpret the guideline or explain how it is to be applied. Failure to follow such commentary could constitute an incorrect application of the guidelines, subjecting the sentence to possible reversal on appeal. See 18 U.S.C. § 3742. Second, the commentary may suggest circumstances which, in the view of the Commission, may warrant departure from the guidelines. Such commentary is to be treated as the legal equivalent of a policy statement. Finally, the commentary may provide background information, including factors considered in promulgating the guideline or reasons underlying promulgation of the guideline. As with a policy statement, such commentary may provide guidance in assessing the reasonableness of any departure from the guidelines.
