Defendant Luis Carbone appeals from the district court’s denial of his motions for post-conviction relief under Fed.R.Crim.P. 33 and 28 U.S.C. § 2255. Carbone was convicted by a jury of conspiracy with intent to distribute cocaine in violation of 21 U.S.C. § 846, aiding and abetting in the possession of half a kilogram of cocaine with intent to distribute it, and aiding and abetting in the distribution of half a kilogram of cocaine in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2. The conviction was affirmed by this Court in
United States v. Carbone,
In addition to arguing that the district court erred in denying his request for a new trial on the basis of newly discovered evidence and an alleged “unauthorized evi-dentiary finding” by this Court, defendant argues that the court should at least have held an evidentiary hearing before ruling on the motions. Given that we are not persuaded by defendant’s arguments, we affirm.
First, defendant argues that a new trial is in order because newly discovered evidence establishes that he was deprived of effective assistance of counsel in violation of the sixth amendment of the United States Constitution. Defendant contends that his attorney did not pursue viable defenses available to Carbone because of a conflict of loyalties in his representation. He claims that his attorney abandoned an in-depth cross-examination of Jose Rios, a government informant, due to an earlier agreement the attorney had entered into with the government involving Rios’ role in another drug prosecution case. There is no indication in the record, however, that the alleged conflict of interest adversely affected defense counsel’s performance in cross-examining Rios, nor was the alleged conflict an active conflict- of interest.
See Cuyler v. Sullivan,
We find no abuse of discretion in the district court’s determination that defendant is not entitled to a new trial on the basis of ineffective assistance of counsel. Carbone has been unable to show that his attorney’s performance in cross-examining Rios fell below an objective standard of reasonableness. The transcript indicates that such cross-examination was vigorous and was well within the range of competence required of defense counsel in criminal cases. Furthermore, defendant is unable to establish by a long shot that there is a reasonable probability that but for the alleged ineffective assistance the outcome of the trial would have been different. As this Court explained in the earlier affirmance, “[t]he evidence against defendant was overwhelming; he was convicted by the words out of his own mouth.”
*1502 Second, defendant also argues that a new trial should be granted based on newly discovered evidence uncovering the alleged perjury of Burgos Colon, one of the government’s key witnesses at trial. Car-bone alleges that there is substantial evidence that Burgos lied when he testified that he sold half a kilogram of cocaine to Carbone. According to defendant, Burgos told a fellow inmate at the Commonwealth Penitentiary at Rio Piedras that he had never entered into a drug transaction with defendant. Defendant has also provided this Court with a supplemental offer of proof regarding the alleged perjury of Bur-gos at trial on the subject of his plea agreement which provided for his testifying against Carbone. For purposes of this appeal, we allow the defendant’s related motion to supplement the record. We conclude, however, that the district court’s denial of defendant’s request for a new trial should not be disturbed.
Given that defendant has alleged that Burgos’ testimony implicating defendant in the drug transaction was perjured, the applicable analysis is arguably the test described in
Larrison v. United States,
Defendant’s supplemental offer of proof regarding Burgos’ alleged perjury at trial as to the nature of his plea agreement raises an issue of impeachment evidence. Though impeachment evidence may be significant in a close case, this was by no means a close case. Such evidence is deemed to be immaterial at this juncture and cannot serve as grounds for a new trial under Fed.R.Crim.P. 33.
Third, defendant argues that it was error for the district court not to conduct an evidentiary hearing before ruling on the post-conviction motions. A hearing is not necessary in cases where a § 2255 motion “(1) is inadequate on its face, or (2) although facially adequate, is conclusively refuted as to the alleged facts by the files and records of the case.”
Moran v. Hogan,
Fourth, Carbone challenges this Court’s earlier review of the audibility of the tape recordings submitted at trial as an “unauthorized evidentiary finding” by an appellate court. Defendant argues that he is entitled to a new trial on this basis. Without addressing the issue of whether defendant can properly raise such a challenge at this juncture, we fail to see any merit in defendant’s argument. This Court played all of the tapes at the time of defendant’s earlier appeal and concluded “that none of them were so inaudible or unintelligible as to make them more misleading than helpful.”
Accordingly, the district court’s judgment is affirmed.
Notes
. We note that at the time of Carbone’s initial appeal this Court mentioned the possibility of his filing a new motion in the district court "accompanied by a statement from Noriega that he is willing to testify and an offer of proof covering the subject matter of his testimony.”
