This revision is made to conform the rule to changes made by the Judicial Improvements Act of 1990.

Committee Notes on Rules—2000 Amendment

The language of Rule 101 has been amended, and definitions have been added, as part of the general restyling of the Evidence Rules to make them more easily understood and to make style and terminology consistent throughout the rules. These changes are intended to be stylistic only. There is no intent to change any result in any ruling on evidence admissibility.

The Style Project

The Evidence Rules are the fourth set of national procedural rules to be restyled. The restyled Rules of Appellate Procedure took effect in 1998. The restyled Rules of Criminal Procedure took effect in 2002. The restyled Rules of Civil Procedure took effect in 2007. The restyled Rules of Evidence apply the same general drafting guidelines and principles used in restyling the Appellate, Criminal, and Civil Rules.

1. General Guidelines

Guidance in drafting, usage, and style was provided by Bryan Garner, Guidelines for Drafting and Editing Court Rules, Administrative Office of the United States Courts (1969) and Bryan Garner, A Dictionary of Modern Legal Usage (2d ed. 1995). See also Joseph Kimble, Guiding Principles for Restyling the Civil Rules, in Preliminary Draft of Proposed Style Revision of the Federal Rules of Civil Procedure, at page x (Feb. 2005) (available at; Joseph Kimble, Lessons in Drafting from the New Federal Rules of Civil Procedure , 12 Scribes J. Legal Writing __ (2008-2009).

2. Formatting Changes

Many of the changes in the restyled Evidence Rules result from using format to achieve clearer presentations. The rules are broken down into constituent parts, using progressively indented subparagraphs with headings and substituting vertical for horizontal lists. “Hanging indents” are used throughout. These formatting changes make the structure of the rules graphic and make the restyled rules easier to read and understand even when the words are not changed. Rules 103, 404(b), 606(b), and 612 illustrate the benefits of formatting changes.

3. Changes to Reduce Inconsistent, Ambiguous, Redundant, Repetitive, or Archaic Words

The restyled rules reduce the use of inconsistent terms that say the same thing in different ways. Because different words are presumed to have different meanings, such inconsistencies can result in confusion. The restyled rules reduce inconsistencies by using the same words to express the same meaning. For example, consistent expression is achieved by not switching between “accused” and “defendant” or between “party opponent” and “opposing party” or between the various formulations of civil and criminal action/case/proceeding.

The restyled rules minimize the use of inherently ambiguous words. For example, the word “shall” can mean “must,” “may,” or something else, depending on context. The potential for confusion is exacerbated by the fact the word “shall” is no longer generally used in spoken or clearly written English. The restyled rules replace “shall” with “must,” “may,” or “should,” depending on which one the context and established interpretation make correct in each rule.

The restyled rules minimize the use of redundant “intensifiers.” These are expressions that attempt to add emphasis, but instead state the obvious and create negative implications for other rules. The absence of intensifiers in the restyled rules does not change their substantive meaning. See, e.g., Rule 104(c) (omitting “in all cases”); Rule 602 (omitting “but need not”); Rule 611(b) (omitting “in the exercise of discretion”).

The restyled rules also remove words and concepts that are outdated or redundant.

4. Rule Numbers

The restyled rules keep the same numbers to minimize the effect on research. Subdivisions have been rearranged within some rules to achieve greater clarity and simplicity.

5. No Substantive Change

The Committee made special efforts to reject any purported style improvement that might result in a substantive change in the application of a rule. The Committee considered a change to be “substantive” if any of the following conditions were met:

a. Under the existing practice in any circuit, the change could lead to a different result on a question of admissibility (e.g., a change that requires a court to provide either a less or more stringent standard in evaluating the admissibility of particular evidence);

b. Under the existing practice in any circuit, it could lead to a change in the procedure by which an admissibility decision is made (e.g., a change in the time in which an objection must be made, or a change in whether a court must hold a hearing on an admissibility question);

c. It alters the structure of a rule in a way that may alter the approach that courts and litigants have used to think about, and argue about, questions of admissibility (e.g., merging Rules 104(a) and 104(b) into a single subdivision); or

d. It changes a “sacred phrase” — phrases that have become so familiar in practice that to alter them would be unduly disruptive. Examples in the Evidence Rules include “unfair prejudice” and “truth of the matter asserted.”
