In 2009, the Committee on Rules of Practice and Procedure of the Judicial Conference of the United States Courts decided to “restyle” the Federal Rules of Evidence. The goal in this project was to make the Rules more user friendly rather than to enact substantive changes. At the end of each section of this casebook, there is a side-by-side comparison between the prior language of each portion of Rule 412 and the language of the new “restyled” Rule. Because the changes were intended to be stylistic only, everything discussed in this chapter should continue to be good law after the “restyled” Rules take effect on December 1, 2011.
