This report assesses the continuing impact on the federal sentencing system of the Supreme Court's 2005 opinion in United States v. Booker, which rendered the sentencing guidelines advisory. Part A of the report discusses the history of the federal sentencing guidelines and the post-Booker sentencing and appellate processes. It also reports the results of statistical analyses of federal sentencing data spanning a broad time frame, from October 1995 through September 2011, and provides recommendations for strengthening the federal sentencing guidelines system. Parts B through F contain more detailed descriptions of appellate court decisions, additional charts, tables, and graphs depicting sentencing data, and a description of other stakeholders' proposals for sentencing reform. Appendices to Parts B through F include additional data and tables, summaries of relevant public hearings, and a summary of the Commission's 2010 survey of district judges.
