OPINION OF THE COURT
Appellant Alfonzo Coward was convicted for violating 18 U.S.C. § 922(g)(1) (2001), possession of a firearm by a felon. His appeal raises two issues: (1) whether the District Court erred in denying his motion to suppress on the ground that the government faded to present at the suppression hearing essential evidence of reasonable suspicion to justify the stop of Coward’s vehicle, and (2) whether § 922(g)(1) is a constitutional exercise of Congress’ Commerce Clause powers. This court recently decided the latter issue in
United States v. Singletary,
I.
BACKGROUND
At the pretrial suppression hearing, Philadelphia Police Lieutenant Michael Chitwood testified that on the evening of September 23, 1998, he and his partner, Terrence Sweeney, were patrolling the
Almost immediately after hearing this call, Officers Chitwood and Sweeney saw the vehicle and pulled it over. Chitwood testified that prior to, approaching the vehicle, he saw the driver reach for the glove compartment and duck down under the passenger seat before returning to an upright position. When the officers approached the car, the - driver, later identified as Coward, stated, “It’s not mine.” App. at 61. Chitwood then observed a nine-millimeter weapon on the floor of the passenger’s side. 1 ‘
Chitwood’s testimony was the only evidence offered by the government at the suppression hearing to support the legality of the stop. The government did not present the testimony of the officer who requested the stop by radio nor any evidence demonstrating the reason for the request to stop Coward’s vehicle.
The defense argued that all evidence arising out of the stop of Coward’s vehicle should be suppressed for lack of reasonable suspicion to justify the stop. In response, the government argued that it “was a lawful stop ... [b]ased on the radio call.” App. at 97. The government argued that the “ ‘fellow officer rule’ ... kind of imputes the knowledge of the transmitting officer to the receiving officer, whether it is actually transmitted or not.” App. at 98. The government advised the District Court both in its memorandum and at the oral argument that there was authority in the Ninth Circuit’s decision in
United States v. Robinson,
Following the arguments of the government and counsel for Coward, the District Court at the pretrial hearing on January 4, 2001, denied the motion to suppress, noting that it was sufficient that Chitwood reasonably relied on the radio request. App. at 101 (stating that Chitwood’s testimony demonstrated “ample reasonable suspicion, indeed fear, on the part of ... Chitwood thatfled] to the search”). In an amendment to the order to suppress filed the same day, the District Court added that the burden was on the defendant to show that there was no reasonable suspicion behind the police radio request. The court stated:
The question then becomes who has the burden of showing that there was no reasonable suspicion behind the police radio request. It seems to us that the Government, having prima facie shown the reasonableness of Sergeant Chit-wood’s behavior, should not have to take on the added burden of looking behind the request from police radio. Since the defendant has as much access to thisproof as the Government, it seems to us not excessive to place the burden of such proof upon the party claiming that the radio dispatch was illegitimate. As there is not a scintilla of evidence in this record regarding such illegitimacy, we will not infer it retrospectively absent some basis for doing so.
App. at 27. On February 26, 2001, the defense moved to reconsider that order and on March 5, 2001, the District Court denied that motion reiterating the reasons given in the January 4, 2001 Order. App. at 124.
Thereafter, evidence derived from the stop of Coward’s vehicle was admitted at the jury trial. On June 13, 2001, Coward was found guilty of being a felon in possession of a firearm that had traveled in interstate commerce in violation of 18 U.S.C. § 922(g)(1) and was sentenced to sixty-eight months imprisonment and three years of supervised release. Coward moved for a judgment of acquittal pursuant to Federal Rule of Criminal Procedure 29(c) on the Commerce Clause issue. The District Court denied his motion.
United States v. Coward,
II.
DISCUSSION
A.
Suppression of Evidence
We review the District Court’s denial of the motion to suppress for clear error as to the underlying factual findings and we exercise plenary review over questions of law.
United States v. Perez,
1. Proof of Reasonable Suspicion
The government concedes, as it must, that it did not meet its burden of proof in establishing that the stop of Coward’s car was based on reasonable suspicion. Br. of Government at 4. The government further acknowledges that the District Court incorrectly shifted'the burden of proof to the defendant on this issue.
Under the applicable law, the government was required to present evidence at the suppression hearing of the requesting police officer’s reasonable suspicion. In
Whiteley v. Warden,
The Supreme Court reached a similar result in
United States v. Hensley,
[W]hen evidence is uncovered during a search incident to an arrest in reliance merely on a flyer or bulletin, its admissibility turns on whether the officers who issued the flyer possessed probable cause to make the arrest. It does not turn on whether those relying on the flyer were themselves aware of the specific facts which led their colleagues to seek their assistance.
Id.
at 231,
In addition, the District Court erred in holding the burden was on the defense to prove reasonable suspicion. Once a defendant has challenged the admissibility of such evidence, the government must bear the burden of proving the existence of reasonable suspicion.
See Florida v. Royer,
The parties do not dispute that the evidence offered in the District Court was insufficient or that the burden of proving reasonable suspicion should have been on the government. The only question before us is the appropriate resolution. Coward requests that we reverse the denial of his motion to suppress and order a new trial at which all evidence derived from the stop of his vehicle will be suppressed. The government requests that we remand the case to allow the District Court to decide whether the government should be given an opportunity to introduce new evidence on the issue of reasonable suspicion.
2. Reopening the Suppression Hearing
The question of whether the government may augment the record at a suppression hearing after a remand following the conviction of the defendant is analogous to the question of whether the government may reopen its case after resting.
United States v. Vastola,
Our decision in
Kithcart II
provides our most recent analysis of this issue. In
United States v. Kithcart,
In
Kithcart II,
we set forth a number of factors that a court must consider in deciding whether to permit reopening. We stated that “[w]hen faced with a motion to reopen, the district court’s primary focus should be on whether the party opposing reopening would be prejudiced if reopening is permitted.”
If [the motion to reopen] comes at a stage in the proceedings where the opposing party will have an opportunity to respond and attempt to rebut the evidence introduced after reopening, it is not nearly as likely to be prejudicial as when reopening is granted after all parties have rested, or even after the case has been submitted to the jury. Where, as in this case, reopening is permitted after the government has rested its case in chief, but before the defendant has presented any evidence, it is unlikely that prejudice sufficient to establish an abuse of discretion can be established.
The Blankenship court offered further guidelines for courts to use in deciding whether to reopen a proceeding:
In exercising its discretion, the court must consider the timeliness of the motion, the character of the testimony, and the effect of the granting of the motion. The party moving to reopen should provide a reasonable explanation for failure to present the evidence in its case-in-chief. The evidence proffered should be relevant, admissible, technically adequate, and helpful to the jury in ascertaining the guilt or innocence of the accused. The belated receipt of such testimony should not imbue the evidence with distorted importance, prejudice the opposing party’s case, or preclude an adversary from having an adequate opportunity to meet the additional evidence offered.
Id.
(quoting
United States v. Thetford,
In
Kithcart II,
we placed emphasis on the need for an adequate explanation of the failure to present the relevant evidence earlier. “In order to properly exercise its discretion the district court must evaluate that explanation and determine if it is both reasonable, and adequate to explain why the government initially failed to introduce evidence that may have been essential to meeting its burden of proof.”
Kithcart II,
We have made clear that the “ ‘party moving to reopen should provide a reasonable explanation for failure to present the evidence [initially].’ ”
Kithcart II,
Unlike in
Kithcart II
where the government offered no explanation for its failure to present the evidence, the government in this case offers two justifications for its failure to produce evidence that would have satisfied its burden of proof: (1) a mistake due to the “relative inexperience” of the prosecutor, and (2) the acquiescence of the judge. The government proffers no evidence of its assertion that the prosecutor was indeed inexperienced, stating that such proof would be provided on remand. We note that the prosecutor’s “inexperience” did not prevent the government from selecting her to handle the obligations of a criminal trial and, indeed, she secured Coward’s conviction. Moreover, there is testimony at the suppression hearing suggesting that the prosecutor was familiar with the controlling precedent on this issue. App. at 98-99 (discussing applicability of
Hensley
and
Berg).
In fact, at the suppression hearing the prosecutor quoted from
United States v. Robinson,
A district court may consider the purpose for reopening. In
Blankenship,
the court stated, “[r]eopening is often permitted to supply some technical requirement such as the location of a crime — needed to establish venue — or to supply some detail overlooked by inadvertence.”
We refrain from expressing our view as to whether the government has provided a reasonable and adequate explanation for its failure to present evidence that the requesting officer had reasonable suspicion to justify the stop, because we believe the District Court is the appropriate body to weigh the government’s arguments and evidence in favor of reopening. In
Vastola,
we remanded the determina
For the reasons articulated, we will remand to the District Court to evaluate the government’s request to reopen the suppression hearing in light of the considerations expressed herein.
B.
Validity of Section 922(g)
In Coward’s 'brief, he argued that possession of a firearm that has previously traveled in interstate commerce does not have a substantial relation to and/or impact on interstate commerce and thus falls outside of Congress’ authority under the Commerce Clause, U.S. Const., art. I, § 8, cl. 3. On that basis, Coward argued that 18 U.S.C. § 922(g)
3
was not constitutionally applied to him. However, his brief was written without the benefit of this court’s recent decision in
United States v. Singletary,
In
Singletary,
we examined this precise issue in detail and held that “proof ... that the gun had traveled in interstate commerce, at some time in the past, was sufficient to satisfy the interstate commerce element” of the statute.
Id.
at 205. Taking note of our prior decision in
United States v. Gateward,
Despite the rejection of identical constitutional challenges in Singletary, Coward maintains that Singletary did not address his challenges based on statutory construction and thus has no preclusive effect over those challenges. Reply Br. at 5-6. Coward argues that the term “possess in or affecting interstate commerce” in § 922(g) cannot include the intrastate possession of a gun that once traveled in interstate commerce because to do so would violate three principles of statutory construction: (1) the rule of lenity and strict construction of criminal statutes; (2) the necessity to construe statutes to give meaning to each phrase and render no phrase superfluous; and (3) the rule that statutes be construed to avoid grave constitutional questions. Br. of Appellant at 23-31.
Although
Singletary
does not directly address these rules of statutory construc
III.
CONCLUSION
For the reasons stated herein, we will remand this case to the District Court to decide, in its discretion, whether to allow the government to present additional evidence in opposition to the suppression motion. In so considering, the District Court must consider the factors articulated above, including whether or not the government has an adequate and reasonable explanation for its failure to present the evidence initially and whether the presentation of additional evidence will prejudice the defendant.
Notes
. Coward disputes these facts, specifically whether he reached in the car and whether he made any statement to the officers, but these factual disputes are not relevant to the issues on appeal.
. Although the government noted that under Robinson, "the officer who issues a Wanted Bulletin must have a reasonable suspicion sufficient to justify a stop,” App. at 96, it did not advise the court of the government’s necessity to produce such evidence.
. 18 U.S.C. § 922(g) reads in part:
(g) It shall be unlawful for any person— (1) who has been convicted in any court of, a crime punishable by imprisonment for a term exceeding one year; ts ship or transport, in interstate or foreign commerce, or possess in or affecting commerce, any firearm or ammunition; or to receive any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.
