HEANEY, Senior Circuit Judge.
In 1982, Mary Lee Orsini was convicted in Pulaski County, Arkansas, Circuit Court, for the capital murder of Alice McArthur. She was sentenced to a term of life imprisonment without parole. Her conviction was affirmed by the Arkansas Supreme Court, Orsini v. State, 281 Ark. 348, 665 S.W.2d 245 (1984), and the United States Supreme Court denied certiorari. Orsini v. Arkansas, 469 U.S. 847, 105 S.Ct. 162, 83 L.Ed.2d 98 (1984). Orsini then petitioned unsuccessfully for state post-conviction relief. Orsini v. State, 287 Ark. 456, 701 S.W.2d 114 (1985).
Orsini subsequently petitioned for a writ of habeas corpus in the United States District Court for the Eastern District of Arkansas. She asserted sixteen separate grounds for relief. A United States magistrate, proceeding with the consent of the parties and pursuant to the congressional grant of authority in 28 U.S.C. § 636(c), entered a final judgment denying Orsini’s petition without an evidentiary hearing. Orsini appeals from the final judgment of the magistrate. She contends on appeal that: (1) she was denied due process when prior inconsistent statements of material witnesses and when the details of special inducements given to “Yankee” Hall, a co-conspirator, to testify against Orsini were withheld by the prosecutor’s office; (2) she was denied her right to a fair trial because the prosecutor permitted the known perjured testimony of three key material witnesses, including that of “Yankee” Hall, to stand unrefuted at trial, released Hall’s close-up confession implicating Orsini a few days before trial, and engaged in other misconduct; (3) she was denied her right to a fair trial as a result of pretrial publicity; and (4) she received ineffective assistance [476]*476of counsel at trial and on direct appeal.1 We initially address, sua sponte, the question of whether the magistrate had jurisdiction to hear and render final judgment on Orsini’s habeas petition.
I. JURISDICTION
The parties concede that statutory authority exists for a magistrate to enter final judgment on a habeas petition with the consent of the parties involved. They do so even though the Federal Magistrates Act has been consistently given a narrow interpretation. See Gomez v. United States, — U.S.-, 109 S.Ct. 2237, 2240, 104 L.Ed.2d 923 (1989); United States v. Trice, 864 F.2d 1421, 1429 (8th Cir.1988). Because this issue involves the subject matter jurisdiction of this Court, an independent determination of this issue is in order. Upon review of the language and history of the Federal Magistrates Act, we believe that Congress intended for magistrates to be authorized to conduct habeas proceedings within the limitations set forth in 28 U.S.C. § 636(c)(1). See Sinclair v. Wainwright, 814 F.2d 1516, 1519 (11th Cir.1987).
Section 636(c)(1) provides, in pertinent part:
(c) Notwithstanding any provision of law to the contrary-—
(1) Upon consent of the parties, a full-time United States magistrate or a part-time United States magistrate who serves as a full-time judicial officer may conduct any or all proceedings in a jury or nonjury civil matter and order the entry of judgment in the case, when specially designated to exercise such jurisdiction by the district court or courts he serves.
28 U.S.C. § 636(c)(1) (1988). Both requisites are met in this case.2
Because habeas proceedings are customarily characterized as civil proceedings, e.g., Hilton v. Braunskill, 481 U.S. 770, 776, 107 S.Ct. 2113, 2118, 95 L.Ed.2d 724 (1987); Stewart v. Bishop, 403 F.2d 674, 677 (8th Cir.1968), the plain language of section 636(c) — even in light of the specific inclusion of habeas petitions in section 636(b)(1)(B) — indicates that magistrates, upon consent of the parties and reference by the district court, have jurisdiction to order entry of judgment in a habeas case.
While an argument can be made that Congress did not intend to authorize magistrates to enter judgments in habeas petitions, we do not believe that it withstands careful scrutiny. In our view, the legislative history confirms the plain meaning of section 636(c). In 1976, in an effort to overrule Wingo v. Wedding, 418 U.S. 461, 94 S.Ct. 2842, 41 L.Ed.2d 879 (1974),3 Con[477]*477gress passed section 636(b)(1)(B), intending the language “notwithstanding any provision of law to the contrary” to “overcome any problem which may be caused by the fact that scattered throughout the code are statutes which refer to ‘the judge’ or ‘the court.’ ” H.R.Rep. No. 1609, 94th Cong., 2d Sess. 9 (1976), reprinted in 1976 U.S. Code Cong. & Admin.News 6162, 6169. In 1979, Congress passed section 636(c) with the same “notwithstanding any provision of law to the contrary” language. Although in this latter instance Congress did not specify its intention, it is fair to assume that Congress intended the same effect by the language in the 1979 Act as Congress did in the 1976 Act.4 Also in 1979, the Supreme Court amended Rule 10 of the Rules Governing Section 2254 Cases in United States District Courts to provide a generic grant of authority: “The duties imposed on the judge of the district court by these rules may be performed by a United States magistrate pursuant to 28 U.S.C. § 636.” In light of this, we believe that Congress intended section 636(c), as the plain language indicates, to authorize magistrates to enter judgments in habeas proceedings on consent of the parties and reference by the district court.
We next ask whether section 636(c) comports with Article III of the Constitution. In a non-habeas case, this Court, sitting en banc, held that it does not violate Article III for Congress to delegate case dispositive authority, which is the essence of the judicial power of the United States, to a non-Article III officer. Lehman Bros. Kuhn Loeb v. Clark Oil & Refining, 739 F.2d 1313 (8th Cir.1984). Eleven other circuits accept this view.5 We reasoned that section 636(c) did not violate Article III because Article III courts firmly “control” each magistrate. Id. at 1316. This “control” results from the Judicial Conference participating in decisions regarding the pay, locale, and number of magistrates; the district court retaining the discretion to refer or recall any case from the magistrate; and review by a court of appeals as a matter of right. Id. at 1315-16. Judges Lay, Arnold and Bowman dissented.6
The only circuit to address the constitutionality of section 636(c) in a habeas setting is the Eleventh Circuit in Sinclair v. Wainwright, 814 F.2d at 1519. In that case, Senior Judge J. Smith Henley of the Eighth Circuit, sitting by designation, [478]*478wrote an opinion holding section 636(c) constitutional, even in the habeas setting. Id. He reasoned that the provision was constitutional because consent was required and the district court retained some control over the magistrate. Id.
Orsini asserts that Lehman is not dispos-itive in this case because of the nature of the habeas proceeding. We disagree. Nothing in this Court’s opinion in Lehman indicates that our holding was limited to jurisdiction over civil, non-habeas matters.7 See Lehman, 739 F.2d at 1316; Sinclair, 814 F.2d at 1519. Moreover, Orsini’s arguments fail because none of the arguments relate to- traditional Article III concerns.8 [479]*479Finally, Orsini’s argument that a remand is in order because her consent was uncoun-seled also fails because she did not raise that issue initially to this Court. Therefore, we hold that for purposes of Article III, section 636(c) is constitutional and that the magistrate had subject matter jurisdiction to enter judgment.
II. THE DUE PROCESS AND FAIR TRIAL ISSUES
When one has had an opportunity to thoroughly digest Orsini’s claims that she was denied due process and a fair trial, it becomes clear that the answer turns on several incidents involving “Yankee” Hall’s pretrial statements and his testimony at trial.
“Yankee” Hall was the state’s principal witness. Prior to trial Hall agreed with Sheriff Tommy Robinson and Prosecutor Wilbur “Dub” Bentley that in return for the state accepting his plea of guilty to first degree murder, rather than to capital murder, he would sign a confession detailing all the events surrounding his and Orsi-ni’s involvement in the murder of Alice McArthur. (A person found guilty of capital murder must be sentenced to death or life without parole. A person found guilty of first degree murder is eligible for parole.) Pursuant to a plea agreement, Hall gave and signed a long and detailed confession on August 29, 1982. In that confession Hall stated that he had been hired by Orsini to murder Alice McArthur. He recited that Orsini had been promised $15,000 by William McArthur, Alice’s husband, if she would arrange the murder. Hall declared that he and Orsini attempted to bomb Alice McArthur’s car, that the bomb had exploded, but that Alice McArthur was not injured. Hall stated that Orsini approached him again and stated that William McArthur still wanted his wife killed and had raised the ante to $25,000. Hall and Orsini then worked out a plan to kill Alice McArthur in her home. Hall then stated that he hired Larry McClendon, who was a friend of his from the penitentiary, to be the trigger man. According to Hall, the $25,000 payment was to be split among himself, McClendon, and Orsini.
Hall stated that the plan was to have him and McClendon gain entry into the McAr-thur home by posing as flower delivery men. He stated that Orsini furnished the gun, a clip board, and a florist sign to lend reality to the flower delivery scheme. Or-sini stole the murder weapon from a man she had been dating for several weeks, Dr. C.H. Wulz. On July 2, 1982, the date set for the murder, Hall picked up the flowers. Hall and McClendon then drove to the Mc-Arthur home in a car with the florist sign in the window. McClendon rang the doorbell. When the door was opened by Alice McArthur, McClendon entered the home and shot and killed her. Hall later threw the gun, sign, and clipboard into the river. Neither Hall nor McClendon was paid for the murder.
Hall was arrested on July 5, 1982, and McClendon was arrested on July 6, 1982. On July 4, 1982, Hall gave an oral statement to Little Rock police officers indicating that he barely knew Orsini and that she knew nothing of the murder. He added that he had not talked to her since the murder. Hall’s July 4th statement was not given to Orsini before or during the trial. Orsini obtained it through the Arkansas Freedom of Information Act.
On September 2, 1982, Hall’s August 29th confession was leaked to the Arkansas Democrat, a major Arkansas daily newspaper. With the release of the confession to the newspaper, a publicly aired controversy between Prosecutor Bentley and Sheriff Robinson broke out, and stories about the murder were in the newspaper for several days. The thrust of the controversy between Bentley and Robinson was that Robinson wanted William McArthur to be indicted and tried, but Bentley argued that there was insufficient evidence upon which to base an indictment of McArthur.9 Hall’s [480]*480August 29th confession was not introduced at trial. He testified, however, and his testimony was consistent with his confession.
We now relate Orsini’s contention on appeal to the factual situation just described. Her first contention, that prior inconsistent statements were suppressed, relates primarily to the July 4th statement that Hall gave to the police to the effect that he did not know Orsini well and that she knew nothing about the murder. Her second contention, that the details of the special inducements given to witnesses in return for their testimony were withheld by the state, relates primarily to her assertion that Robinson told Hall that when he was elected governor, he would commute Hall’s life sentence and that Hall would be released after only a few years. Orsini’s third contention, that the prosecutor permitted the perjured testimony of three key material witnesses to stand unrefuted at trial, again relates primarily to inconsistencies between Hall’s July 4th and August 29th statements.10 She hypothesizes that Hall’s July 4th statement was true and that the August 29th confession and trial testimony were the result of the special inducement offered by Robinson.
The magistrate, assuming the truth of Orsini’s allegations, found that the withheld statements were not material and refused to grant the petitioner habeas relief. He did so on the basis of United States v. Bagley, 473 U.S. 667, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985). In that case the Supreme Court held that evidence in nondisclosure cases is material only if “there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.” Id. at 682, 105 S.Ct. at 3383. A “reasonable probability” is a probability sufficient to undermine confidence in the outcome. Id. This court followed the Bag-ley standard in United States v. Peltier, 800 F.2d 772 (8th Cir.1986).
This case is one in which we cannot say that the evidence other than Hall’s statement was so strong that the jury would have convicted Orsini had Hall’s statement been suppressed. There can be little doubt that his detailed statement was a major factor in the jury’s verdict of guilty. The question thus becomes whether Hall’s credibility, which was subject to question because of his past convictions and life style, would have been weakened by the withheld evidence to the point that the jury probably would have rejected his testimony implicating Orsini. In light of all the evidence presented at trial, we do not believe that it would have been.
(1) Dr. Wulz testified at trial. He conceded that he had a close and intimate relationship with Orsini over a period of several weeks. He stated that the gun used to kill Alice McArthur was his, that the bullets used in the gun were identical to bullets that he had purchased several years ago, and that five bullets were missing from the box of bullets that he kept in his home. He further testified that Orsini had access to his home. No evidence was presented tending to show that either Hall or McClendon had similar access, that the home had been broken into, or that the weapon was stolen by a prowler. This unrefuted evidence powerfully supported Hall’s testimony that Orsini recruited him to kill Alice McArthur.
(2) Two witnesses, Carl Wilson and Tammy Oaks, testified that Orsini accompanied Hall to Wilson’s home the day they picked up the explosives used to bomb Alice McAr-thur’s car. This evidence supports Hall’s testimony that he and Orsini had planned to murder Alice McArthur for a long period of time.
(3) At least two witnesses testified that Orsini called the McArthur home several times on the day of the murder. The government’s theory was that the calls were made to determine whether Alice Mc-Arthur was at home. This evidence lends [481]*481weight to Hall’s testimony that Orsini was the organizer and facilitator of the murder.
(4) A short time after the murder occurred, Orsini prepared a handwritten script for a proposed telephone conversation between her and Larry Burge. Pursuant to the script, Burge called Orsini at her home. Orsini knew her phone was tapped by authorities. In that conversation, she indicated that she had been tipped off that a man named Larry McClendon had killed Alice McArthur. She did not implicate Hall personally, but stated that McClendon had an accomplice, referring to the accomplice as a “white man who ran with McClendon.” This evidence supports Hall’s testimony that Orsini concocted the plan to murder Alice McArthur.
(5) Hall knew details of the Orsini home. This information tended to support his statement that he had been in Orsini’s home on six occasions prior to the murder and that he had been intimate with Orsini.
In sum, we believe that in light of this evidence, the jury would have found Hall’s testimony and August 29th statement credible even if Orsini had been able to impeach Hall’s testimony with the July 4th statement and the deal between Hall and Sheriff Robinson.
Orsini argues that Wilson’s testimony is also suspect because the prosecution failed to disclose that Wilson had given an earlier statement to federal authorities in which he stated that he was unable to identify Orsini from a photograph as the woman who accompanied Hall to Wilson’s farm when Hall picked up the explosives. She also contends that Wilson had been given immunity from prosecution and that fact was not made known to her or her counsel before trial. Although Wilson’s prior failure to identify Orsini from the photograph may have had an impact on the jury, any such impact would have been weakened by the identification of Orsini by an independent witness who was also present at the Wilson farm. Moreover, Orsini’s statement that she did not know that Wilson had been given immunity is simply not supported by the record.
Orsini argues that Burge’s testimony is also subject to question because he gave a statement prior to trial which contradicted his trial testimony and because he was given immunity from prosecution. Neither fact, she alleges, was revealed to the defense. There is no merit to her first assertion. The pretrial statement simply was not exculpatory in nature. In it, Burge admitted that he made a call to Orsini’s home in an attempt to recreate an anonymous call Orsini had allegedly received regarding the murder of Alice McArthur. We have more concern with respect to the failure of the state to reveal to Orsini that Burge was testifying under a grant of immunity, but the taped telephone conversation sufficiently buttressed his testimony.
In summary, the record reveals that the state withheld exculpatory information from Orsini and that it had no excuse for the withholding. Were the standard one which permitted reversal for the repeated withholdings, Orsini would prevail. The Bagley test, however, requires that we determine whether the withheld information probably would have caused the jury to reach a different result. Here, we do not believe that it would have.
III. PRETRIAL PUBLICITY
Orsini also contends that she was denied her constitutional right to a fair trial as a result of pretrial publicity generated by the state and that the trial court erred by denying her motion for a change of venue. In particular, she points to the intentional release of Hall’s August 29th statement. While we cannot be certain whether the prosecutor’s office or the sheriff’s office released Hall’s statement, our review of the record indicates that it probably was the sheriff’s office. It also appears that the purpose of this release was to pressure the prosecutor’s office to indict William McArthur, the victim’s husband and Orsi-ni’s attorney at the time of the murder. The underlying purpose, however, is irrelevant. The impact on Orsini of the pretrial publicity is the same.
Because this case involved violence, politics, and sex, it generated tremendous [482]*482publicity. The magistrate found that the facts of this case were “more highly publicized than any other criminal trial in recent Arkansas history.” Orsini v. Wallace, No. 86-585, slip op. at 38 (E.D.Ark. Sept. 16, 1988). The determinative inquiry is not, however, the amount of publicity but rather the effect that the publicity had on prospective jurors. See, e.g., Clark v. Wood, 823 F.2d 1241, 1244 (8th Cir.1987). An appellate court reviewing for error asks whether the jurors can, despite the publicity, lay aside their impressions and opinions and render a verdict, in all fairness, based on the evidence presented at trial. See Murphy v. Florida, 421 U.S. 794, 800, 95 S.Ct. 2031, 2036, 44 L.Ed.2d 589 (1975); Clark v. Wood, 823 F.2d at 1244.
Orsini raised these contentions on direct appeal to the Arkansas Supreme Court. That court rejected them. Orsini v. State, 665 S.W.2d at 250-51 (citing Singleton v. State, 274 Ark. 126, 623 S.W.2d 180 (1981); Conley v. State, 270 Ark. 886, 607 S.W.2d 328 (1980)). The magistrate agreed. Orsini v. Wallace, No. 86-585, slip op. at 38-40 nn. 40-41 (E.D.Ark. Sept. 16, 1988).
Under 28 U.S.C. § 2254(d)(8), federal court review of state court findings of fact is limited. The trial court held an eviden-tiary hearing. At this hearing, Orsini and the state presented evidence on whether Orsini could receive a fair trial in Pulaski County. After hearing all the evidence, the trial court concluded that Orsini could receive a fair trial.11 Our review of the change of venue hearing indicates that the trial court’s decision not to change venue is fairly supported by the record. Furthermore, Orsini presents no new evidence or theories different from those presented to the Arkansas Supreme Court and the magistrate. Both held that Orsini’s right to a fair trial was not infringed by publicity. We accept that decision, albeit with some reluctance.
IV. INEFFECTIVE ASSISTANCE OF COUNSEL
Orsini contends that her counsel at trial and on direct appeal provided ineffective assistance. Her specific allegations are that counsel at trial did not object to the introduction of evidence concerning the bombing of the victim’s car; failed to identify Winston Talley, who would have testified that Orsini was not with Hall when Hall was at Carl Wilson’s home; failed to discover Hall’s inconsistent statements to Terry Wolf and Dennis Montgomery that Orsini was not involved in the murder; failed to obtain information regarding Prosecutor Bentley’s visit to the Arkansas Repertory Theatre to confirm Dr. Wulz’ testimony that Orsini was with him the night Alice McArthur’s car was bombed; failed to object to Prosecutor Bentley’s presence in the courtroom even though he had assigned the case to another prosecutor; failed to object to the testimony of Gail Endleman, who testified that a woman was trying to locate the victim on the day of the murder; failed to obtain a copy of the police report containing contrary information prepared by the North Little Rock Police Department; failed to interview police officers regarding a “hit list” on which Orsini’s name appeared; failed to obtain the statements of Robin Hall, Susie Peoples, and Norita Carreras that Orsini did not frequent bars with Hall; failed to obtain information regarding the special deal between Hall and Sheriff Robinson; failed to interview Dr. Wulz and Lynn Frazier regarding the performance at the theater; failed to elicit evidence regarding the immunity of Larry Burge; failed to ask Phoebe Pinkston specific questions regarding a conversation between Orsini and the victim; and were generally unprepared. She also alleges that her post-trial counsel was ineffective because he attempted to sell privileged information to a local tele[483]*483vision station, allowed personal problems to interfere with his duties to Orsini, lied to her, did not consult with her about certain decisions, failed to seek disqualification of two Arkansas Supreme Court Justices, misinformed her about the procedure for raising on appeal the issue of recanted trial testimony, and failed to obtain inconsistent statements of Hall and Carl Wilson.
Orsini raised many, if not all, of these allegations at her proceeding for post-conviction relief, pursuant to A.R.Cr.P. Rule 37. The Arkansas Supreme Court denied her request for an evidentiary hearing. Orsini v. State, 287 Ark. 456, 701 S.W.2d 114, 119 (1985). It found no merit to any of her claims. Id. “None of the many points raised by the petitioner would void her conviction. Petitioner has also failed to establish that her counsel at trial or on appeal were ineffective.” Id.
The magistrate reached and denied each of these allegations individually. Orsini v. Wallace, No. 86-585, slip op. at 44-58 (E.D. Ark. Sept. 16, 1988). In concluding, the magistrate found that her counsel at trial and on direct appeal were not ineffective. Id. at 58.
Our review of the record indicates that Orsini’s counsel were not ineffective for the reasons stated in the magistrate’s opinion. In each of her allegations, Orsini fails to demonstrate the path or direction that “reasonable” counsel would have taken. Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 2064, 80 L.Ed.2d 674 (1984). While she alleges which path she would have taken, she fails to give any explanation as to why “reasonable” counsel would have taken the same path. Thus, she does not overcome the presumption of reasonableness given to tactical decisions of counsel. Furthermore, we believe that she has not shown the requisite prejudice. See id. She has failed to assert any evidence or theory upon which we could find that conduct of her counsel undermined confidence in the outcome of her trial, sentencing, or appeal. See Chambers v. Armontrout, 907 F.2d 825, 832-33 (8th Cir.1990).
V. CONCLUSION
The magistrate’s denial of Orsini’s petition for habeas relief is affirmed. Because the evidence wrongly withheld by the state would not have been “material” in light of the standard set forth in Bagley, she was not denied due process. Likewise, pretrial publicity did not deny Orsini’s right to a fair trial, and she did not receive ineffective assistance of counsel. Finally, the magistrate had jurisdiction to enter final judgment in Orsini’s habeas petition.
