Exclusion of Witnesses
At the request of a party the court shall order witnesses excluded so that they cannot hear the testimony of other witnesses, and it may make the order of its own motion. This rule does not authorize exclusion of (1) a party who is a natural person, or (2) an officer or employee of a party which is not a natural person designated as its representative by its attorney, or (3) a person whose presence is shown by a party to be essential to the presentation of the partys cause.
Gender-neutralizing amendments were made to this rule in 1987.
Note (Federal Judicial Center)
The rule enacted by the Congress is the rule prescribed by the Supreme Court, amended only by substituting "court," in place of "judge," with conforming pronominal changes.
Advisory Committees Note
The efficacy of excluding or sequestering witnesses has long been recognized as a means of discouraging and exposing fabrication, inaccuracy, and collusion. 6 Wigmore §§1837-1838. The authority of the judge is admitted, the only question being whether the matter is committed to his discretion or one of right. The rule takes the latter position. No time is specified for making the request.
Several categories of persons are excepted. (1) Exclusion of persons who are parties would raise serious problems of confrontation and due process. Under accepted practice they are not subject to exclusion. 6 Wigmore §1841. (2) As the equivalent of the right of a natural-person party to be present, a party which is not a natural person is entitled to have a representative present. Most of the cases have involved allowing a police officer who has been in charge of an investigation to remain in court despite the fact that he will be a witness. United States v. Infanzon, 235 F.2d 318 (2d Cir. 1956); Portomene v. United States, 221 F.2d 582 (5th Cir. 1955); Powell v. United States, 208 F.2d 618 (6th Cir. 1953); Jones v. United States, 252 F. Supp. 781 (W.D. Okl. 1966). Designation of the representative by the attorney rather than by the client may at first glance appear to be an inversion of the attorney-client relationship, but it may be assumed that the attorney will follow the wishes of the client, and the solution is simple and workable. See California Evidence Code §777. (3) The category contemplates such persons as an agent who handled the transaction being litigated or an expert needed to advise counsel in the management of the litigation. See 6 Wigmore §1841, n.4.
Report of Senate Committee on the Judiciary
Many district courts permit government counsel to have an investigative agent at counsel table throughout the trial although the agent is or may be a witness. The practice is permitted as an exception to the rule of exclusion and compares with the situation defense counsel finds himself inhe always has the client with him to consult during the trial. The investigative agents presence may be extremely important to government counsel, especially when the case is complex or involves some specialized subject matter. The agent, too, having lived with the case for a long time, may be able to assist in meeting trial surprises where the best-prepared counsel would otherwise have difficulty. Yet, it would not seem the government could often meet the burden under Rule 615 of showing that the agents presence is essential. Furthermore, it could be dangerous to use the agent as a witness as early in the case as possible, so that he might then help counsel as a nonwitness, since the agents testimony could be needed in rebuttal. Using another, nonwitness agent from the same investigative agency would not generally meet government counsels needs.
This problem is solved if it is clear that investigative agents are within the group specified under the second exception made in the rule, for "an officer or employee of a party which is not a natural person designated as its representative by its attorney." It is our understanding that this was the intention of the House committee. It is certainly this committees construction of the rule.
