  No. 89-1134
  Summary Calendar.
  United States Court of Appeals, Fifth Circuit.
  March 28, 1990.
  Rehearing Denied April 25, 1990.
  Larry Wayne Samples, Texarkana, Tex., pro se.
  Delonia A. Watson, Asst. U.S. Atty., Marvin Collins, U.S. Atty., Dallas, Tex., for plaintiff-appellee.
  Before CLARK, Chief Judge, WILLIAMS and DUHÉ, Circuit Judges.
  PER CURIAM:
  I.
  A federal grand jury returned a one-count indictment against appellant Larry Wayne Samples charging him with the interstate transport of a stolen aircraft in violation of 18 U.S.C. § 2312. Samples filed a motion acknowledging his desire to plead guilty pursuant to Rule 20 of the Federal Rules of Criminal Procedure. The district court permitted Samples’ retained counsel to withdraw from the case, and appointed new counsel. Samples pled guilty and was sentenced to four years in prison. He did not appeal the conviction.
  Samples filed a pro se motion to vacate his sentence pursuant to 28 U.S.C. § 2255. He contended that his guilty plea was entered involuntarily because of threats to his life and to the safety of his family. He also claimed that his appointed counsel was ineffective. The district court denied his motion. Samples appealed the denial' to this court, which ordered that Samples be given an evidentiary hearing. A hearing was held before a magistrate who recommended that Samples’ motion be denied and his action dismissed. The district court rejected Samples’ objections and adopted the magistrate’s findings. Samples filed the present appeal.
  II.
  A. The Speedy Trial Act
  Samples argues that the trial court erred in denying his request for a speedy hearing. He claims that the Speedy Trial Act, 18 U.S.C. § 3161 (1985), applies to those seeking post-conviction relief, citing Smith v. Hooey, 393 U.S. 374, 89 S.Ct. 575, 21 L.Ed.2d 607 (1969). Section 3161(c)(1) is applicable to the trial of any defendant who is charged with an offense and who pleads not guilty. There is no statutory or constitutional right to the disposition of a § 2255 motion within a specific time. 28 U.S.C. § 1657 requires that courts expedite such actions. This requirement is relative, not specific. No showing was made that the action was delayed beyond the requirements of the court’s docket. Samples’ argument lacks merit.
  B. The Magistrate’s Authority
  Samples contends that the trial court erred in allowing the magistrate to conduct the evidentiary hearing. We disagree. The Federal Magistrate’s Act, 28 U.S.C. § 636(b)(1)(B) (Supp.1989), explicitly provides:
  a judge may also designate a magistrate to conduct hearings, including evidentia-897 F.2d — 7 ry hearings, and to submit to a judge of the court proposed findings of fact and recommendations for the disposition, by a judge of the court, of any motion excepted in subparagraph (A), of applications for posttrial relief made by individuals convicted of criminal offenses and of prisoner petitions challenging conditions of confinement.
  C.Subpoenas
  Samples’ third argument is that the district court erred in restricting his right to subpoena witnesses at the evidentiary hearing. Samples requested subpoenas at government expense for ten named individuals. He indicated in his request that the first seven individuals would testify about the threats directed toward Samples which he claimed led to his guilty plea. He stated that the eighth and ninth witnesses had knowledge of physical evidence of these threats (the broken windshield of his truck). The last witness, Samples’ former attorney, was requested to testify about prior proceedings.
  The magistrate concluded as to the first seven individuals: “[fjrom the representations in the motion it appears that the testimony which these persons are able to give is cumulative.” The magistrate permitted Samples to choose three of the seven, and they were subpoenaed. The magistrate also subpoenaed one of the two witnesses who were to testify about the condition of the vehicle because the testimony of both was also expected to be cumulative. The magistrate did not permit a subpoena to issue as to Samples’ former attorney because there was no indication that this attorney, who was appointed to represent Samples in a subsequently filed case, could testify about Samples’ claims of ineffective assistance of counsel or the involuntary guilty plea. “This Court has generally given district courts wide discretion in determining whether subpoenas should issue under Rule 17(b).” United States v. Ramirez, 765 F.2d 438, 441 (5th Cir.1985), cert. denied, sub nom. Perpignond v. United States, 474 U.S. 1063, 106 S.Ct. 812, 88 L.Ed.2d 786 (1986). The court may exercise its discretion to deny subpoenas “if the Government demonstrates that the indigent’s averments are untrue, or if the requested testimony would be merely cumulative or irrelevant.” United States v. Webster, 750 F.2d 307, 329-30 (5th Cir.1984), cert. denied, 471 U.S. 1106, 105 S.Ct. 2340, 85 L.Ed.2d 855 (1985) (citations omitted.)
  In this case, Samples’ own motion demonstrated the duplicative nature of the proposed testimony. On appeal, Samples complains that a critical witness, Paula Wom-ack, was not subpoenaed, yet Samples did not exercise the opportunity he was given to choose her as one of his three witnesses from that group.
  Samples failed to show how the testimony of his former attorney, John Bass, would be relevant. Samples did not “allege facts that, if true, demonstrate^] ‘the necessity of the requested witness’ testimony.’ ” Webster, 750 F.2d at 329 (quoting United States v. Hegwood, 562 F.2d 946, 952 (5th Cir.1977), cert. denied, 434 U.S. 1079, 98 S.Ct. 1274, 55 L.Ed.2d 787 (1978)). Bass was not involved in Samples’ case until after sentencing. He could not testify about the proceedings in question. The district court acted properly in limiting the number of subpoenas issued on Samples’ behalf.
  D. Counsel
  Samples argues that the magistrate erred when he found that Samples’ court-appointed attorney had provided “imminently sound” advice. First, he states that the attorney, Dudley P. Andrews, was primarily a civil attorney who should not have been appointed in a criminal case. Samples also contends that Andrews advised Samples that he would be charged with contempt of court if he withdrew his guilty plea.
  The Strickland test applies to guilty plea challenges based on ineffective assistance of counsel. Hill v. Lockhart, 474 U.S. 52, 57, 106 S.Ct. 366, 369-70, 88 L.Ed.2d 203 (1985). This test requires the petitioner to demonstrate not only that his lawyer’s conduct was deficient, but also that he was prejudiced by this deficiency. Strickland v. Washington, 466 U.S. 668, 687, 104 S.Ct. 2052, 2064, 80 L.Ed.2d 674 (1984). The petitioner must show that his counsel’s actions “fell below an objective standard of reasonableness,” id. at 688, 104 S.Ct. at 2064, and that a reasonable probability exists that “but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Id. at 694, 104 S.Ct. at 2068. A reviewing court “must judge the reasonableness of counsel’s challenged conduct on the facts of the particular case, viewed as of the time of counsel’s conduct,” id. at 690, 104 S.Ct. at 2066, and must strongly presume that counsel has exercised reasonable professional conduct. Lockhart v. McCotter, 782 F.2d 1275, 1279 (5th Cir.1986), cert. denied, 479 U.S. 1030, 107 S.Ct. 873, 93 L.Ed.2d 827 (1987).
  The evidence presented at the hearing does not show ineffective assistance of counsel. Samples testified at the hearing that he never told Andrews about any of the threats or violent incidences. Andrews also testified that Samples told him that he wanted to withdraw his guilty plea simply because he didn’t want to go to prison. He also stated that he did not recall ever seeing Samples appear in a beaten or injured state. Therefore, Samples did not provide Andrews with any “fair and just reason” for the withdrawal of Samples’ guilty plea under Fed.R.Crim.P. 32(d). Samples’ ineffectiveness claim does not meet the first prong of the Strickland test. Samples also fails to satisfy the second prong of the test because testimony was presented at the evidentiary hearing that Samples had been told by Assistant U.S. Attorney Jo'seph Revesz that he could plead not guilty. Thus, there is no indication of prejudice to Samples. The determination that Samples had no ineffective assistance of counsel claim is supported by the testimony presented at the evidentiary hearing.
  E. Cross-examination
  Samples contends that the magistrate erred by restricting the cross-examination of Melissa Murphy, the appellant’s ex-wife. He claims that the magistrate treated Murphy with “kid gloves,” and that this prevented the disclosure of impeaching information. He claims that she has a drug habit and that she was intimately involved with federal marshals.
  Murphy, however, was questioned about her involvement with federal marshals. She denied ever dating a marshal. The magistrate did not permit questions regarding Murphy’s alleged drug-related arrests. This was appropriate under Fed. R.Evid. 608(a), which provides:
  “[t]he credibility of a witness may be attacked or supported by evidence in the form of opinion or reputation, but subject to these limitations: (1) the evidence may refer only to character for truthfulness or untruthfulness, and (2) evidence of truthful character is admissible only after the character of the witness for truthfulness has been attacked by opinion or reputation evidence or otherwise.”
  The magistrate permitted questions about Murphy’s drug use on particular instances, such as on the dates that she appeared for the July 1985 arraignment and the August 1985 sentencing. As the magistrate pointed out, general questions relating to drug use would be irrelevant.
  F. The Hearing
  Samples contends that the hearing was “artificially conducted and predetermined.” He further accuses the trial court of “throwing handicap weights on the government’s side of the balancing scale.” He specifically contends that the magistrate erred in allowing assistant U.S. attorney Joseph Revesz to remain in the courtroom despite Samples’ invocation of Federal Rule of Evidence 615. He also claims: “the trial court continually interrupted the hearing while questions were being posed, or answers were being given.” He claims that this was done to cause a change in the direction of the testimony or to prevent the clear presentation of the facts.
  The trial court’s decision of who will be sequestered can be reversed only upon a clear showing of abuse of discretion. United States v. Alvarado, 647 F.2d 537, 540 (5th Cir.1981). The determination that Revesz fell within the second exemption to Rule 615, which applies to “an officer or employee of a party which is not a natural person designated as its representative by its attorney,” was within the discretion of the magistrate. See United States v. Nix, 601 F.2d 214, 215 (5th Cir.), cert. denied, 444 U.S. 937, 100 S.Ct. 287, 62 L.Ed.2d 196 (1979); Portomene v. United States, 221 F.2d 582 (5th Cir.1955).
  Samples’ accusation that the hearing was biased is without merit. Samples was given a full opportunity to present his issues. The transcript of the proceeding covers 383 pages. The trier of fact in a federal forum is not confined to a silent or passive role. It is common practice for a judge or magistrate to ask questions of a witness for clarification. As the government points out in its brief, this Court has expressly stated that the trial judge “may comment on the evidence, may question witnesses and elicit facts not yet adduced or clarify those previously presented.” Moore v. United States, 598 F.2d 439, 442 (5th Cir.1979).
  Samples argues that his court-appointed attorney at the evidentiary hearing, Robert Hyder, provided ineffective assistance of counsel by failing to interview Samples and his witnesses prior to the evidentiary hearing. This claim does not pass Strickland muster. The transcript of the hearing reflects that Hider had adequate knowledge of Samples’ case. Hider’s performance was not deficient, as he made pertinent objections, thoroughly examined the witnesses, and displayed competence in developing facts within the limits of the Federal Rules of Evidence. Moreover, Samples’ assertion that attorney Hider was unprepared finds no support in the transcript of the evidentiary hearing. Hider’s questions reflected a clear understanding of what Samples was trying to establish. This claim is frivolous.
  G. Findings
  Samples maintains that the trial court erred in refusing to credit the unimpeached testimony of his witnesses. Samples complains that he presented witnesses who testified that they had seen Samples being beaten or had seen Samples’ damaged vehicle. He also argues that his son testified that he had heard attorney Dudley Andrews tell Samples that he could not revoke the Rule 20 motion acknowledging his desire to plead guilty.
  The trier of fact need not credit any witness’ testimony, even if unimpeached. “An appellate court is in no position to weigh conflicting evidence and inferences or to determine the credibility of witnesses; that function is within the province of the finder of fact.” Strauch v. Gates Rubber Co., 879 F.2d 1282, 1285 (5th Cir.1989), cert. denied, — U.S. -, 110 S.Ct. 841, 107 L.Ed.2d 836 (1990) (citing Boeing v. Shipman, 411 F.2d 365, 374 (5th Cir.1969) (en banc).
  Melissa Murphy provided conflicting and damaging testimony at the hearing. She testified that Samples requested that she testify that she had been threatened and that Samples had been threatened and beaten. She further testified that Samples had never exhibited any signs of a beating. She stated that the windshield of the truck was broken at the time she and Samples had purchased it.
  The magistrate apparently credited her testimony instead of that provided by other witnesses, several of whom were immediate family members of Samples. His choice between conflicting testimony is not subject to reweighing on this appeal.
  III.
  The judgment of the district court is AFFIRMED.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  In some cases there is some confusion over who should be listed as the appellant and who as the respondent. This confusion is primarily the result of the presence of multiple docket numbers consolidated into a single appeal that is disposed of by a single opinion. Most frequently, this occurs when there are cross appeals and/or when one litigant sued (or was sued by) multiple litigants that were originally filed in district court as separate actions. The coding rule followed in such cases should be to go strictly by the designation provided in the title of the case. The first person listed in the title as the appellant should be coded as the appellant even if they subsequently appeared in a second docket number as the respondent and regardless of who was characterized as the appellant in the opinion.
  To clarify the coding conventions, consider the following hypothetical case in which the US Justice Department sues a labor union to strike down a racially discriminatory seniority system and the corporation (siding with the position of its union) simultaneously sues the government to get an injunction to block enforcement of the relevant civil rights law. From a district court decision that consolidated the two suits and declared the seniority system illegal but refused to impose financial penalties on the union, the corporation appeals and the government and union file cross appeals from the decision in the suit brought by the government. Assume the case was listed in the Federal Reporter as follows:
  United States of America,
  Plaintiff, Appellant
  v
  International Brotherhood of Widget Workers,AFL-CIO
  Defendant, Appellee.
  International Brotherhood of Widget Workers,AFL-CIO
  Defendants, Cross-appellants
  v
  United States of America.
  Widgets, Inc. & Susan Kuersten Sheehan, President & Chairman
  of the Board
  Plaintiff, Appellants,
  v
  United States of America,
  Defendant, Appellee.
  This case should be coded as follows:Appellant = United States, Respondents = International Brotherhood of Widget Workers Widgets, Inc., Total number of appellants = 1, Number of appellants that fall into the category "the federal government, its agencies, and officials" = 1, Total number of respondents = 3, Number of respondents that fall into the category "private business and its executives" = 2, Number of respondents that fall into the category "groups and associations" = 1.
  Note that if an individual is listed by name, but their appearance in the case is as a government official, then they should be counted as a government rather than as a private person. For example, in the case "Billy Jones & Alfredo Ruiz v Joe Smith" where Smith is a state prisoner who brought a civil rights suit against two of the wardens in the prison (Jones & Ruiz), the following values should be coded: number of appellants that fall into the category "natural persons" =0 and number that fall into the category "state governments, their agencies, and officials" =2. A similar logic should be applied to businesses and associations. Officers of a company or association whose role in the case is as a representative of their company or association should be coded as being a business or association rather than as a natural person. However, employees of a business or a government who are suing their employer should be coded as natural persons. Likewise, employees who are charged with criminal conduct for action that was contrary to the company policies should be considered natural persons.
  If the title of a case listed a corporation by name and then listed the names of two individuals that the opinion indicated were top officers of the same corporation as the appellants, then the number of appellants should be coded as three and all three were coded as a business (with the identical detailed code). Similar logic should be applied when government officials or officers of an association were listed by name.
  Your specific task is to determine the total number of appellants in the case that fall into the category "private business and its executives". If the total number cannot be determined (e.g., if the appellant is listed as "Smith, et. al." and the opinion does not specify who is included in the "et.al."), then answer 99.
