Christopher Dennis and William McCoy filed separate appeals from a judgment of conviction following a jury verdict finding both defendants guilty of conveying homemade knives within the United States Penitentiary at Marion, Illinois, in violation of 18 U.S.C. § 1792. The appeals were consolidated for argument. We affirm the conviction of both defendants.
I. Factual Background
On May 23, 1982 prison officials observed two inmates attempting to climb on to the roof of the north corridor at the federal penitentiary in Marion, Illinois. When the alarm sounded, both inmates dropped to the ground and walked away. As they were leaving the north corridor, each dropped an object from inside his coat to the ground. Officials cleared and searched the area immediately and discovered two homemade knives. They also identified Dennis and McCoy as the two inmates.
II. Contentions on Appeal
Both appellants contend that the district court committed reversible error in denying (1) their request for a recess following voir dire to permit the defendants and their counsel to confer out of the jury’s presence regarding the exercise of peremptory challenges; (2) a motion for mistrial after a government witness testified to an “escape attempt”, and (3) motions for judgment of acquittal. In addition, appellant Dennis contends that he was denied a speedy trial under the Speedy Trial Act of 1974 as amended, 18 U.S.C. § 3161.
*619 III. Request for Recess after Voir Dire
At the conclusion of voir dire, appellants’ counsel requested a recess to confer with their clients out of the jury’s presence about the use of their peremptory challenges. The court denied the request but granted additional time to confer in the courtroom. Appellants contend that they were denied a fair trial “because of the restrictions placed on their ability to confer with counsel concerning the exercise of their peremptory challenges.”
In
United States v. Mackey,
The manner in which peremptory challenges are exercised is within the sound discretion of the trial court, and in the absence of violation of settled principles of criminal law, federal statutes, or constitutional rights of defendant, such discretion is not abused.
Id. at 502. (citations omitted). Appellants fail to point out any settled principle of criminal law, federal statute or constitutional right contravened by the court’s practice in this case. We find no abuse of discretion by the district court. Moreover, appellants have failed to demonstrate that they suffered more than inconvenience in conferring with counsel out of the hearing but in the presence of the jury. Any conceivable error was harmless and not a ground for reversal. Fed.R.Crim.P. 52(a); 28 U.S.C. § 2111.
IV. Motion for Mistrial
Prior to trial the parties agreed that no comments would be made and no testimony elicited concerning the escape attempt since the defendants had not been charged with escape. At no time during its opening statement or closing arguments did the prosecution allude to an attempted escape. On direct examination, however, one government witness mentioned “an escape attempt.” Defendants moved for a mistrial, but the court denied the motion after the government explained that the testimony was inadvertent and sought to caution the witness against returning to the prohibited subject. Defendants objected to these preventive efforts, and the district court “let it go at that.” 1 Apparently, no cautionary instruction was requested or given and no motion to strike was made.
In
United States v. Phillips,
V. Motion for Judgment of Acquittal
At the close of the government’s case and again at the close of all of the evidence, appellants moved for acquittal. The district court denied both motions. Appellants contend “in light of the lack of evidence introduced by the government ... no rational trier of fact could have found proof of guilt beyond a reasonable doubt.”
The standard for appellate review of a motion for judgment of acquittal is the same as the standard applied by the trial court:
The rule has long been established that when ruling on a motion for acquittal the test that the court must use is whether at the time of the motion there was relevant evidence from which the jury could reasonably find [the defendant] guilty beyond a reasonable doubt, viewing the evidence in the light most favorable to the Government ... bearpng] in mind *620 that “it is the exclusive function of the jury to determine the credibility of witnesses, resolve evidentiary conflicts, and draw reasonable inferences.”
United States v. Beck,
VI. Speedy Trial
Appellant Dennis contends that his conviction must be reversed because his trial did not begin within the 70-day period provided under the Speedy Trial Act, 18 U.S.C. § 3161(c)(1). 2 The government offers two responses: (1) Dennis’ trial was timely if we exclude, under 18 U.S.C. § 3161(h)(7), the time necessary to bring McCoy to trial; and (2) Dennis’ trial was also timely if we exclude, under section 3161(h)(1)(F), the time devoted to pretrial motions.
Both Dennis and McCoy were indicted by a grand jury on January 20, 1983 and joined for trial. Dennis’ 70-day limit began to run on January 26 when he was arraigned before the United States Magistrate, who scheduled his trial for March 7. McCoy could not be arraigned immediately because he had been transported out of the district on a preceding writ of habeas corpus ad prosequendum for prosecution on a different charge in federal court in Kansas. In the meantime, Dennis filed pretrial motions on February 15, and the court ruled on them at a pretrial conference on February 28. On March 3 the government moved to continue Dennis’ trial. The court granted the motion on March 29, 1983 and set a new trial date.
McCoy was finally arraigned on April 15, and on May 4 Dennis-unsuccessfully moved to dismiss the indictment for failure to accord him a- speedy trial. McCoy then moved to continue the trial, and the court granted McCoy’s motion on May 11. Again Dennis moved to dismiss on speedy trial grounds on May 16. The court denied the motion on June 11, finding the delay was not unreasonable and was excludable under section 3161(h)(7) because Dennis had not moved to sever his case from that of his codefendant McCoy. Trial finally began on June 20.
18 U.S.C. § 3161(h)(7) excludes from the time within which trial must begin “[a] reasonable period of delay when the defendant is joined for trial with a codefendant as to whom the time for trial has not run and no motion for severance has been granted.” It is well established under this section that the excludable delay of one defendant may be ascribed to all codefendants in the same case, absent severance. See
United States v. Campbell,
In determining whether the delay was reasonable we are guided by the purpose Congress intended to serve when it enacted section 3161(h)(7). As the court observed in
United States v. Novak,
The purpose of the provision is to make sure that [the Senate Bill] does not alter the present rules of severance of code-fendants by forcing the government to prosecute the first defendant separately or to be subject to a speedy trial dismissal motion under section 3162.
S.Rep. No. 1021, 93d Cong., 1st Sess. 38 (1974) (quoted in
United States v. Novak,
Whether the delay was reasonable will depend on the facts of each case. There is no doubt that the delay was reasonable here: McCoy was in custody and his whereabouts known at all times; while the government did not know precisely when McCoy could be produced, there was never any doubt that he would be produced; the delay was necessary to insure a joint trial; the 144-day delay preceding Dennis’s trial was not “presumptively prejudicial” under the terms of
Barker v. Wingo,
Finally, we note that whatever formula we use to compute the excluded time will not alter our conclusion. The Guidelines to the Administration of the Speedy Trial Act, produced by the Judicial Conference of the United States, suggest starting and ending dates for the exclusion under section 3161(h)(7):
Starting date. The day following the day that would otherwise have been the last day for commencement of trial for the particular defendant.
Ending date. Subject to the “reasonableness” limitation, the latest permissible date for commencement of the trial of any codefendant with whom the defendant is joined for trial. Alternatively, if earlier, the date on which the defendant’s joinder ends because serverance is granted, the codefendant pleads guilty, or other reasons.
Guidelines at 52.
If we were to follow the
Guidelines,
the last day for Dennis’ trial would have been April 20.
3
Taking April 21 as the starting
*622
date, there is no question that the trial on June 20 was well within the excluded time under section 3161(h)(7). We decline, however, to select a single formula for computing the excluded time because, as other courts have observed, the purposes of the Speedy Trial Act may be undermined by rigid adherence to one formula. See
United States v. Novak,
The convictions of both defendants are
Affirmed.
Notes
. After government counsel proposed that he be permitted to caution the witness against any further reference to the escape attempt, the court said: "Let the record show that you [Government Counsel] made the offer and that the Defendants objected to it so that clears the record. You tried to straighten out and avoid errors and the Defendants objected to that so we will let it go at that."
. 18 U.S.C. § 3161(c)(1) provides: “In any case in which a plea of not guilty is entered, the trial of a defendant charged in an information or indictment with the commission of an offense shall commence within seventy days from the filing date (and making public) of the information or indictment, or from the date the defendant has appeared before a judicial officer of the court in which such charge is pending, whichever date last occurs____”
. This computation excludes 14 days devoted to Dennis’ pretrial motions under section 3161(h)(1)(E) and (G). We need not decide whether additional periods, including proceedings on the government’s motion to continue, Dennis’ motions to dismiss, and McCoy’s subse *622 quent motions, are excludable under other subsections of section 3161.
