ROSENTHAL, District Judge:
This is the second appeal arising from the failed prosecution of Daniel Chapman, Sean Flanagan, and Herbert Jacobi for securities and investment fraud. We previously upheld the district court's dismissal of the indictment with prejudice as a sanction for the government's failure to meet its disclosure obligations under Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963) and Giglio v. United States, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972). In the previous appeal, we also affirmed the district court's refusal to award the defendants their attorneys' fees and costs under the Hyde Amendment. United States v. Chapman, 524 F.3d 1073, 1089 (9th Cir.2008).
The defendants moved in the district court to reopen under Federal Rule of Civil Procedure 60(b)(3). The motion is based on an internal government memorandum written shortly after the district court dismissed the indictment. The defendants obtained the memorandum after we decided the prior appeal. The district court denied the motion to reopen and this appeal followed. We conclude that the district court did not abuse its discretion in denying the appellants' Rule 60(b)(3) motion and affirm.
Because the parties are familiar with the factual and procedural history, and because our prior opinion sets out the background facts in detail, they are not repeated here. As the district court's rulings and our prior opinion make clear, the government's failures to meet its Brady and Giglio disclosure obligations amounted to flagrant prosecutorial misconduct that merited the sanction of dismissal with prejudice. The failures were revealed during the aborted trial when the government questioned prosecution witnesses about undisclosed prior convictions. The government initially contended that it had produced documents relating to the prior convictions, but, when the district court asked for evidence of such production, the government "abruptly changed course" and stated that "in an abundance of caution rather than find the record of what we turned over, we'll make another copy of everything right now and provide it to the defense counsel immediately." Chapman, 524 F.3d at 1078. The next day, the defendants' counsel alerted the district court that the government had just delivered hundreds of pages of previously undisclosed documents, "some 650 pages [consisting] of rap sheets, plea agreements, cooperation agreements, and other information related to numerous government witnesses, including at least three important witnesses whose testimony was already complete." Id. at 1079. After a hearing, the district court declared a mistrial and dismissed the indictment with prejudice, stating that the government had acted "flagrantly, willfully, and in bad faith" in withholding impeachment documents. Id. at 1080. The district court denied the defendants' motion for fees and costs on the grounds that the defendants were not "prevailing parties" under the Hyde Amendment and there was no basis to conclude that the entire case against the defendants was "vexatious, frivolous, or in bad faith." Id. at 1088-89.
We affirmed both the dismissal and the denial of relief under the Hyde Amendment. We reasoned that although a dismissal with prejudice "materially alters the legal relationship of the parties . . . our cases have also required a prevailing party to have `receive[d] at least some relief on the merits of his claim.'" Id. at 1089 (quoting United States v. Campbell, 291 F.3d 1169, 1172 (9th Cir.2002)). Because the district court "never suggested that this prosecutorial misconduct was relevant to Defendants' guilt or innocence," and the dismissal "was purely intended to sanction the government's flagrant Brady/Giglio and procedural violations and the misrepresentations used to conceal those violations," we found that the defendants had not received relief on the merits and were not "prevailing parties" as required under the Hyde Amendment. Id. In a footnote, we added:
Id. at 1089 n. 6.
The motion for relief under Rule 60(b)(3) at issue in the present appeal is based on a memo the defendants received from the IRS in response to a subpoena duces tecum issued in a separate case. The memorandum was written by J. Wesley Eddy, the Special Agent in Charge for the Las Vegas office of the IRS's Criminal Investigation Division, three days after the district court dismissed the indictment against the defendants (the "Eddy Memo"). The defendants contend that the following language from the Eddy Memo shows that one of the AUSAs intentionally withheld documents covered by Brady or Giglio:
The Eddy Memo also discusses other issues with the prosecution and trial and notes the conclusion by special agents assigned to the case "that the underlying cause of these issues was the failure of the AUSAs to devote sufficient time to trial preparation." The Eddy Memo was sent to the AUSA who was the first-chair lawyer at the trial.
In the district court, the defendants urged the Eddy Memo as the basis of their Rule 60(b)(3) motion to reopen the Hyde Amendment fee and cost request. The defendants argued that the Eddy Memo showed that the United States had committed a fraud on the court by defending its failures to disclose as unintentional. The defendants also argued that they should be "deemed a prevailing party" because, in light of the Eddy Memo, the dismissal of the indictment was a "judgment on the merits" for the purpose of the Hyde Amendment claim.
After a hearing, the district court denied the defendants' motion. The district court found that the Eddy Memo simply reaffirmed its prior conclusion about the nature and extent of the prosecutorial misconduct.
Rule 60(b)(3) allows a court, "on motion and just terms," to relieve a party. . . from a final judgment . . . for the following reasons: fraud (whether previously called intrinsic or extrinsic), misrepresentation, or misconduct by an opposing party."
The district court acted within its discretion in finding that the Eddy Memo did not show fraud on the court or provide a basis to reopen the case to allow discovery into that issue. Contrary to the defendants' argument, the Eddy Memo is not a revelation of new information about the discovery misconduct during the trial or about the government's subsequent statements about that misconduct. The district court gave what it described as the "Reader's Digest Version" of the Eddy Memo: "This hasn't been turned over, what are we going to do? And [one of the AUSAs] says, we'll handle it on direct." The Eddy Memo shows that one AUSA involved in the case made an intentional decision to delay disclosing certain impeachment information to the defendants, and that other AUSAs disagreed.
The government's statements in the briefs and argument presented in the prior appeal similarly reflected the mix of what the district court described as "not unintentional," "not innocent," and "negligent, sloppy" discovery misconduct in the failed prosecution. This circuit's precedent contemplates a higher level of culpability than that found by the district court found and reflected by the record of the prior appeal. See Latshaw v. Trainer Wortham & Co., 452 F.3d 1097, 1104 (9th Cir.2006) (describing fraud on the court as "`fraud perpetrated by officers of the court'" that prevents the "`judicial machinery'" from "`perform[ing] ... its impartial task of adjudging cases that are presented for adjudication'" (quoting Alexander v. Robertson, 882 F.2d 421, 424 (9th Cir.1989))).
Both parties discuss our decision in Dixon v. Commissioner, 316 F.3d 1041 (9th Cir.2003). In Dixon, tax test-case petitioners entered into secret settlement agreements with opposing IRS counsel before trial in the Tax Court. Before and during trial, the IRS attorneys deceived the court to prevent it from learning about the agreements. Because these test-case petitioners had already settled their claims and had no stake in the outcome, the trial was a "charade fraught with concealed motives, hidden payments, and false testimony." Id. at 1047. When the test-case petitioners attempted to enforce their secret agreements, senior IRS officials became aware of the scheme and informed the court. We overturned the lower court's finding that there was no fraud on the court because no party was prejudiced by the fraud. Noting that "[p]rejudice is not an element of fraud on the court," we emphasized that the IRS attorneys' conduct "was clearly designed to defile the court itself" and "violated the rights of the test case petitioners and the more than 1,300 taxpayers who agreed to be bound by the outcome of the Tax Court proceeding." Id. at 1046-47.
Dixon does not support the defendants' argument that the district court abused its discretion in finding no fraud on the court. The Eddy Memo confirms what the district court already knew when it first denied the defendants' motion for fees and costs under the Hyde Amendment—that the government had affirmatively misrepresented its compliance with its disclosure obligations, both before and after the misconduct was revealed. But as the district court found at that time, and found again in response to the motion now on appeal, the misrepresentations did not "ris[e] to the level of a fraud on the court," amount to a "clear attempt to defile the court," or cause "a charade fraught with concealed" motives. Dixon, 316 F.3d at 1047. Denying the motion on that basis was consistent with our precedents and within the district court's discretion.
The defendants' argument that the Eddy Memo entitles them to reopen the Hyde Amendment issue because it shows that they were prevailing parties is similarly unavailing. Because the Eddy Memo reinforces the earlier determination made by the district court and upheld on appeal, the Memo does not provide a basis to find that the dismissal as a sanction for prosecutorial misconduct made the defendants prevailing parties under the Hyde Amendment. The defendants emphasize that footnote 6 to our decision in Chapman noted that "[i]f documents were intentionally
