This is an appeal from a judgment entered in a diversity action for breach of contract and breach of warranties. Plaintiff, Price Brothers Company, a manufacturer of reinforced concrete pipe, brought this suit against Philadelphia Gear Corporation, claiming that machine components produced by the defendant and used in Price Brothers’ pipe wrapping machine failed to perform as represented. After the parties’ presentation of evidence to the bench on the issues of liability and damages and the receipt of testimony of a court-appointed expert, the district court entered judgment for the plaintiff and awarded it $125,864.15. The defendant appeals from the finding of liability and award of damages. Plaintiff cross-appeals, asserting that the damage award is inadequate.
Philadelphia Gear raises a number of issues on this appeal. For reasons that will become apparent below, we address only the question of the propriety of the alleged conduct of the trial judge in sending his law clerk to view the subject matter of this litigation.
Following the entry of judgment, the plaintiff filed a motion to alter or amend the judgment, pursuant to Rule 59(e), Fed. R.Civ.P., accompanied by defense counsel’s sworn statement that the trial judge’s law clerk had traveled to Beacon, New York, prior to trial, and visited the plaintiff’s plant where he observed Price Brothers’ malfunctioning pipe wrapping machine. *446 Defendant asked the court to amend its findings to reflect the visit. The district judge denied the motion without commenting on whether his clerk had, in fact, made the alleged trip. Philadelphia Gear argues here that the trial court’s reliance on evidence outside the record is clearly erroneous.
We believe that, where a suit is to be tried without a jury, sending a law clerk to gather evidence is so destructive of the appearance of impartiality required of a presiding judge that we must remand this ease for an evidentiary hearing to determine the truth of Philadelphia Gear’s allegation.
We recognize that not every ex parte communication to the trial court requires reversal. In
United States v. Green,
Some conduct is so inimical to the fair and impartial administration of justice, however, that the presumption of prejudice arising therefrom is conclusive and requires an automatic reversal. This principle was recently recognized by this Court in
Standard Alliance Industries, Inc. v. Black Clawson Co.,
In a case analogous to the one before us, the Fifth Circuit reversed a jury verdict for the plaintiff where the trial court permitted its law clerk to testify to what he saw at a curiosity-inspired private view of the scene of a slip-and-fall injury.
Kennedy v. Great Atlantic & Pacific Tea Co.,
We have found no case that addresses the precise issue before us. The principle that reverberates throughout the decisions discussed above, however, is that a judge may not direct his law clerk to do that which is prohibited to the judge. Unquestionably, it would be impermissible for a trial judge to deliberately set about gathering facts outside the record of a bench trial over which he was to preside.
The duty to avoid off-the-record contacts that might influence the outcome of the litigation is expressed in Canon 3(A)(4) of the Code of Judicial Conduct for United States Judges, which provides: “A judge should neither initiate nor consider ex parte . . . communications concerning a pending or impending proceeding. .” Canon 3(C)(1)(a) goes even farther and imposes a duty upon a judge to disqualify himself where his “impartiality might reasonably be questioned” because of his “personal knowledge of disputed evidentiary facts concerning the proceedings.” The problem attendant to a judge having personal knowledge of the facts is that he may thereby be transformed into a witness for one party. Where the trial is to a jury, explicit rules provide some protection. If a judge is to preside, he may not testify. Rule 605, Fed.R.Evid.
1
If he is to testify, he may not preside. 28 U.S.C. § 455.
2
A rule that merely prohibits a presiding judge from testifying in open court, however, does not insure that the fact finder will be “free from external causes tending to disturb the exercise of deliberate and unbiased judgment,”
Mattox
v.
United States, supra,
where the trial is to the bench. Whether, in a bench trial, a judge can avoid an involvement destructive of impartiality where he has personal knowledge of material facts in dispute is a question that cannot be answered satisfactorily,
see
Advisory Committee’s Notes, Rule 605, Fed.R.Evid., and, therefore, a judge should recuse himself in such circumstances.
See, e. g., Roberson v. United States,
The present state of the record raises many questions that must be answered pri- or to any further consideration of the other issues raised on this appeal. We do not know whether the clerk actually visited plaintiff’s plant, though Price Brothers Company does not deny the allegations in its brief. Most importantly, we do not know whether the trip, if made, was at the direction of the trial judge; nor does the record disclose the nature of any conversations the law clerk may have had with plaintiff’s employees, the observations he may have made while at the plant, or whether any of the information obtained on the trip was reported to the judge. It further remains to be discovered at what point defense counsel learned of the trip, and from what source; and whether defense counsel expressly or tacitly approved of the procedure.
We remand for an evidentiary hearing and report. We reserve jurisdiction to consider and pass upon the report, and to consider all further issues raised on this appeal, if it is found that the allegation of impropriety is unfounded.
Notes
. Rule 605, Fed.R.Evid., provides: “The judge presiding at the trial may not testify in that trial as a witness. No objection need be made in order to preserve the point.”
. Title 28 U.S.C. § 455 provides, in part: “Any judge of the United States shall disqualify himself in any case in which he . . . is or has been a material witness . . . .”
