*724OPINION
LUTTIG, Circuit Judge:Appellant Ferebe challenges the district court’s denial of his motion to strike and to bar the United States’ Notice of Intention to Seek the Death Penalty (the “Death Notice”) in his trial for the murders of Yolanda Evans and Benjamin Harvey Page, on the grounds that notice was not provided to him a reasonable time before the trial as required by Title 18, section 3593(a) of the United States Code. Ferebe concedes that the district court’s order denying his motion to strike the Death Notice is not a final judgment, and thus is susceptible to our review only if it is a collateral order, subject to review under the standards articulated in Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). See Under Seal v. Under Seal, 326 F.3d 479 (4th Cir.2003) (discussing the collateral order doctrine and its application in the Supreme Court and in the Fourth Circuit). The government contends that the district court’s order was not a collateral order, but that if it was, the Death Notice was provided to Ferebe a reasonable time before trial, because he was not prejudiced by any tardiness in the filing of the Notice.
This case, having been fully briefed in December 2001, has now been presented to, and considered by, two separate panels of our court. Decision of the matter has been made difficult, both for the first panel that heard this case and for our panel, because the issues presented by the appeal — one jurisdictional, one relating to the governing analytical framework, and one involving application of that framework to the facts of the case — are tightly, if not inextricably, interwoven. This interweave, coupled with the diverging opinions of members of our court as to each issue, made attainment of dispositive agreement especially tricky. Today, however, we reach dispositive agreement on the required statutory analysis, and on its implications for the jurisdictional question.
We conclude that the proper analysis that is to be applied in deciding challenges to the timeliness of a filing under the Death Notice statute, 18 U.S.C. § 3593(a), is that of a pre-trial inquiry into the objective reasonableness of that timing. Because of the characteristics of orders decided under this analytical framework, we conclude that district court orders denying motions to strike Death Notices are collateral orders susceptible to our review. We are unable conclusively to determine the merits of this case, however, because the district court, operating under a different, and incorrect, analytical framework, did not make certain findings critical to the merits determination with sufficient clarity that we may rely on them in this case of life and death. Consequently, we vacate the appealed order and remand the case for further proceedings in the trial court.
I.
Ferebe was first indicted on federal drug, gun, and murder charges, along with a co-defendant, in September 1997.1 The murder charges stemmed from the shooting deaths of Yolanda Evans and Benjamin Harvey Page. Presumably because of the heinousness of the act, the prosecution sought authorization from the United States Attorney General to seek the death penalty for the charged murders. The *725Attorney General, in May 1998, authorized the death penalty for one of the two murders, and only against Ferebe. Because Ferebe alone was eligible for the death penalty, the district court severed Ferebe’s trial from that of his co-defendant.
Ferebe’s co-defendant proceeded to trial, was convicted in October 1998, and was sentenced to life imprisonment in 1999. Ferebe’s trial, however, was continued because Ferebe, already serving a life sentence for a conviction in a related case, preferred to wait until his appeal in that case was final before proceeding in this case. In September 1999, this court affirmed Ferebe’s conviction and sentence in that case, and certiorari was denied by the Supreme Court in early 2000. Around June 2000, the prosecution proposed that Ferebe plead guilty to the charges in this ease and, in exchange, receive concurrent life sentences. Ferebe refused the offer in October 2000.
At a December 2000 hearing, the court scheduled Ferebe’s case for trial in September 2001, and concurrently, the prosecution formally withdrew its outstanding and unaccepted plea offer. Upon the district court’s scheduling of the trial at that December 15, 2000 hearing, nine months remained prior to the start of Ferebe’s trial. At that point, the prosecution had not filed a Death Notice to inform Ferebe and the court formally that it intended to seek the death penalty at Ferebe’s trial, as authorized by the Attorney General.2
Ferebe presents some evidence, and the prosecution does not challenge it, that, nation-wide, federal prosecutors file Death Notices, upon authorization by the Attorney General, with an average of 8.4 months remaining before trial. See J.A. at 82. Such filings are necessitated and governed by section 3593(a), which provides that:
If, in a case involving an offense described in section 3591, the attorney for the government believes that the circumstances of the offense are such that a sentence of death is justified under the chapter, the attorney shall, a reasonable time before the trial or before acceptance by the court of a plea of guilty, sign and file with the court, and serve on the defendant, a notice[.]
18 U.S.C. § 3593(a).
On May 28, 2001, with the trial set to begin in five months time, the prosecution asked the Attorney General to reconsider the decision not to authorize the death penalty on Ferebe’s second murder charge. Before the Attorney General responded, Ferebe’s attorney contacted the prosecution on or about June 15, 2001, and informed it that Ferebe wished to enter a guilty plea, in exchange for concurrent life sentences. The prosecution agreed to the terms and entered into an agreement with Ferebe on June 19. The plea agreement, however, was conditioned on approval by the Attorney General, as just a few weeks earlier (June 7) a new Department of Justice (“DOJ”) policy took effect, requiring prosecutors to obtain the Attorney General’s consent prior to consummating plea agreements with death-eligible defendants.
As a consequence of the parties’ conditional plea agreement, the parties and the district court agreed to postpone several scheduled June and July hearings and conferences. These hearings and conferences had been calendared in order for the parties and the court jointly to prepare trial materials such as the jury questionnaires and to address various pre-trial issues that *726needed to be settled prior to the start of trial on September 10.
On July 6, 2001, two months before Fer-ebe’s trial was set to begin, the Attorney General authorized the death penalty against Ferebe for the second murder, as well as the first .(which of course had been authorized in 1998). Twenty days passed after authorization of the death penalty prosecution as to the second murder before the Attorney General responded to the request for approval of the conditional plea agreement. On July 26, now just a month and a half before Ferebe’s capital trial was set to commence, the Assistant Attorney General in charge of DOJ’s Criminal Division informed the prosecution that the plea agreement was unacceptable.
The district court, the prosecution, and the defense attorney met for a conference on July 31, 2001, just over a month before the scheduled start of Ferebe’s trial, to discuss the case and the ramifications of DOJ’s rejection of the conditional plea agreement. At that meeting, defense counsel responded to the plea agreement’s recision by announcing that Ferebe would still plead guilty to the charges in the absence of a plea agreement (because no Death Notice had yet been filed, Ferebe faced a maximum life sentence).
The next day, August 1, 2001, the prosecution filed a Death Notice for both of the murders with which Ferebe was charged. In light of the government’s filing, Ferebe did not, as he announced he would like to do on the prior day, plead guilty. Instead, Ferebe filed a motion to strike and bar the Death Notice as being untimely filed under section 3593(a)’s requirement that such notices be filed a reasonable time before trial. Pursuant to Ferebe’s motion, the district court set a briefing schedule. The court, on September 7, 2001, held a hearing on the matter, and on September 12 issued an oral opinion denying the motion. It is that order to which this current appeal is directed.
II.
As to the threshold jurisdictional issue, we now hold that district court orders denying motions to strike Death Notices as untimely filed are immediately appealable under Cohen and Abney v. United States, 431 U.S. 651, 97 S.Ct. 2034, 52 L.Ed.2d 651 (1977) (Burger, C.J.), as they fully satisfy the three requirements for interlocutory appeal set forth by the Supreme Court. See Under Seal, 326 F.3d at 483. In Abney, the Supreme Court explained that a “final decision,” as referenced in 28 U.S.C. § 1291, is distinct from a “final judgment,” and “[is] to be given a practical rather than a technical construction,” Abney, 431 U.S. at 658, 97 S.Ct. 2034 (citing Cohen). An order is sufficiently collateral to permit interlocutory appeal if it fully disposes of the issue it addresses, rather than leaves the issue “open, unfinished, or inconclusive,” Abney, 431 U.S. at 658, 97 S.Ct. 2034; “resolves an issue completely collateral to the cause of action asserted,” as opposed to being simply “a step toward final disposition of the merits of the ease,” id.; and “involves an important right which would be lost, probably irreparably, if review ... await[s] final judgment.” Id.
Itself unwilling to advance the position accepted by the dissent, the government does not even argue that the district court’s order denying the motion to strike the Death Notice and setting Ferebe’s capital case for trial is inconclusive or that it is intertwined with the underlying merits of the prosecution. Compare post at 750-751 (Niemeyer, J.) (maintaining that the district court’s order is both inconclusive and intertwined with the merits). The government’s tacit concession that these two prongs of the collateral order inquiry *727are satisfied is understandable. There is no question but that the district court’s order fully disposes of the issue to which it is directed. It denied once and for all the motion to strike and scheduled Ferebe’s case for trial, the very event that Ferebe claims entitlement to avoid, absent a reasonable time for preparation between the time of notice and commencement of trial. See Abney, 431 U.S. at 659, 97 S.Ct. 2034 (finding order denying double jeopardy defense to be conclusive because “no further steps [ ] can be taken in the district court to avoid the trial the defendant maintains is barred by the Fifth Amendment’s guarantee”).
The dissent believes differently, that, until “after [the] trial has occurred,” post at 751, the district court’s order “is merely speculative,” because the pendency of trial necessarily “leaves open the question of the potential prejudice to Ferebe of trying a death penalty case with inadequate preparation time,” post at 751. It believes that the reasonableness of the timing of the Death Notice depends entirely upon “the preparation denied or adversely affected [ie., prejudice] by a notice allegedly given late. And ultimately the adverse effect of preparation [ie., again, prejudice] can only be measured by the defense that the defendant presented at trial.” Id. at 748 (emphasis added).
The flaw in this analysis is an underlying misunderstanding of section 3593(a) and the right created thereby. The right requires, as a prophylactic, reasonable notice before trial. And its indisputable purpose is to ensure that the accused will not be required to stand trial for his life without having received adequate notice before that trial that he is to stand trial for capital offense (in addition to ensuring that an accused will not receive the death penalty without having received such notice). That Congress intended to protect the accused from having to endure a capital trial for which he was provided inadequate notice to prepare his defense is plain from the fact that it required the Death Notice be givén a “reasonable time” before the trial, not merely “before” trial.
As a prophylactic statute, one of the chief aims of which is to protect the accused from having to endure a trial for his life for which he was not on reasonable notice, the statute must be interpreted to require an inquiry into the objective reasonableness of the time between issuance of the Death Notice and the trial itself, in light of the particulars of the charged offense and the anticipated nature of the defense.
Section 3593(a) thus understood, it is evident that an analysis of the finality of the denial of a motion to strike a Death Notice under that section that turns wholly upon a post-trial assessment of prejudice to the accused, as does the dissent’s, see post at 748 (“the adverse effect of preparation [ie., prejudice] can only be measured by the defense that the defendant presented at trial”), cannot possibly be correct. For such an analysis substitutes for the statutorily-mandated inquiry into the pretrial, objective reasonableness of the time between issuance of the Death Notice and trial, a quite different, post-trial inquiry into the prejudice suffered by the accused as a result of the timing of the Death Notice — in effect a “harmless error” inquiry. This is to transform what was intended as a prophylactic statute into a mere remedial one, and to deny to the accused the right afforded by the statute, not merely to avoid sufferance of the punishment of death without adequate notice, but to avoid sufferance of trial for capital offense except upon adequate notice. To assure, as the dissent does, that review may be had at a later time (even post-trial) through a renewal of the motion to strike, *728see post at 751, is to provide no assurance whatsoever, because the right guaranteed to the accused by section 3593(a) not to stand trial for capital offense except upon adequate notice, like the right not to be tried twice for the same offense, is denied if it is recognized only after the trial that the accused is assured by section 3593(a) he will not be required to endure.
The district court’s order denying Fer-ebe’s motion to strike the Death Notice equally indisputably resolves an issue collateral to the merits of the prosecution. The question of whether Ferebe received the statutorily-required reasonable notice is entirely separate from the question of his guilt for the murders committed, and its resolution will neither affect nor be affected by resolution of this latter question. See Abney, 431 U.S. at 659-60, 97 S.Ct. 2034 (deciding that order denying double jeopardy defense is collateral because it is “separable from the principal issue at the accused’s impending criminal trial,” “the [motion of the] defendant makes no challenge whatsoever to the merits of the charge,” and "[t]he elements of that claim are completely independent of his guilt or innocence ’’(emphasis added)).
The dissent comes to the opposite conclusion on this score, as well. But, again, its error is attributable to its errant interpretation of section 3593(a). If one believes, as the dissent does, that section 3593(a) is neither prophylactic in character nor protective of a right not to stand trial except upon adequate notice, and therefore that the timeliness of the Death Notice must be gauged by a post-trial prejudice standard, then its conclusion that the questions of the timeliness of the Death Notice and of the merits of the prosecution are intertwined follows ineluctably. See post at 748 (concluding that “a ‘reasonable’ time must focus on the preparation denied or adversely affected [ie., prejudice] by a notice allegedly given late” and that “the adverse effect of preparation [ie., prejudice] can only be measured by the defense the defendant presented at trial”).
On the dissent’s understanding of section 3593(a), the syllogism that captures the proper analysis of the order’s collateral nature is this: Section 3593(a) does not create an indefeasible right not to stand trial for capital offense except upon reasonable notice. Instead, the statute only ensures that an accused who is convicted and sentenced to death will be afforded a new trial if his conviction and death sentence were the result of an insufficient amount of time within which to prepare for trial. Therefore, whether notice was timely is exclusively a question of whether the conviction and sentence were attributable to an insufficient amount of preparation time, ie., whether actual prejudice was suffered because too little time remained between notice and trial to prepare the death penalty defense. Prejudice, being determined in large part, if not in full, by evaluating whether the accused would have been convicted and sentenced to death absent the alleged error, the questions whether the notice was timely filed and whether the evidence clearly established his guilt are necessarily and inextricably bound up together.
But, of course, the statute is both prophylactic and protective of the right not to be put to trial for capital offense except upon adequate notice. As such, the timeliness of the provided notice, which must be determined pre-trial and objectively, is unquestionably collateral to the question of guilt.
The third and final inquiry under Abney is whether the right allegedly at stake will likely be lost irreparably if immediate review is denied. It is on this prong that the government does pitch its argument, .con*729tending that “Ferebe cannot show irrevocable harm.” Appellant’s Br. at 9-10; see also id. (arguing further that “no rights would be irrevocably lost if he awaits final judgment”). But as to this argument, the government (and the dissent, which accepts the argument) are also wrong, and because of the same misunderstanding of section 3593(a).
The focus in this third prong is not on whether a court can later adjudicate the claim asserted, as the dissent ultimately appears to believe, compare post at 745 (“[T]he order must be effectively unre-viewable on appeal from final judgment.” (emphasis added)), with post at 752 (“Fer-ebe retains the full rights to review and remedy such a violation at the end of the case”). Rather, the focus is on whether the assurances underlying the asserted right will be reneged upon if review is delayed until after trial. See, e.g., Abney, 431 U.S. at 661, 97 S.Ct. 2034 (concluding that this prong was satisfied because rights conferred on the defendant by the Double Jeopardy Clause would be “significantly undermined if appellate review were postponed” since the defendant would lose the assurance of the right that he would not be forced to “endure the personal strain, public embarrassment, and expense of a criminal trial”). Because one of the rights guaranteed by section 3593(a) is that not to be forced to stand trial for one’s life without having received adequate notice of such, it follows, as in Abney with respect to a claim under the Double Jeopardy Clause, that delay in the review of a claimed denial of this right until after the trial itself has taken place is tantamount to countenance of the denial of the right.
On this prong of the analysis, the dissent tilts the playing field, as it were, by moving subtly from the properly framed inquiry — whether the order “remains effectively reviewable upon final judgment,” post at 752—to an entirely different inquiry, namely, whether the order is in fact reviewable post trial, that is, whether, to quote the dissent, Ferebe “retains the full rights to review and remedy [the alleged] violation at the end of the case,” id. at 752 (emphasis added). Says the dissent, “[a]s-suming conviction ... improper notice [can be] vindicated through a new trial.” Id. at 753 (emphasis added).
But, as explained above, and as is plain from Abney and our decision in United States v. Smith, 851 F.2d 706 (4th Cir. 1988) (holding that district court order setting juvenile for trial as an adult constituted an appealable collateral order), the focus of Abney’s third prong is not on whether the question may be reviewed post-trial [i.e., whether Ferebe has a right to post trial review ], it always can be. Rather, the focus is on whether the underlying right will be lost if review is postponed until after trial [ie., has Ferebe lost his section 3593a right, not his right to post-trial review of that underlying right]. Thus the proper question: whether the order is “effectively unreviewable,” not whether it is in fact unreviewable, as the dissent’s conclusion suggests.
Of course, one can only decide whether the underlying right is essentially lost, i.e., whether the order is “effectively unreviewable,” if review is delayed, if one knows what right is protected by the statute. The dissent, tellingly, founds its understanding of the right that is protected by section 3593(a) on a self-contradictory formulation. On the one hand, the dissent states that the section 3593(a) right “is a procedural guarantee that [defendants] will be given adequate time to prepare for a death penalty trial and sentencing.” Post at 37 (emphasis added). On the other hand it states that that guarantee is not a right not to stand trial without that adequate time to prepare for a death penalty *730trial. See post at 747, 748. Having admitted that the section 3593(a) right “guarantees” defendants that they will be given adequate time to prepare for a death penalty trial, the dissent’s subsequent conclusion that the right gives defendants no right not to stand trial without such preparation time is analytically incomprehensible. See infra pp. 731-732 (explaining this subject at greater length).
Since section 3593(a), affirmatively described, creates for defendants not merely the right not to be convicted and sentenced without adequate time to prepare, but also the right not to stand trial for one’s life absent the same, vacature of sentence and remand after trial and sentencing does not protect (nor, for that matter, even remedy the denial of) the right not to be forced to endure a capital trial except upon reasonable notice that one will be required to do so.
Because district court orders denying motions to strike Death Notices under section 3593(a)’s timeliness provision are conclusive, collateral to the merits, and if wrongly decided will irreparably deprive capital defendants of an important right, the appealed order is a reviewable collateral order, and we so hold.
III.
Turning to the merits of the appeal, our interpretation of section 3593(a) reveals that the lower court erred by adopting the analytical framework that it did.3 The district court’s analytical approach (also the premise of the dissent’s jurisdictional analysis) — relying on a prejudice inquiry to vindicate the right created by section 3593(a)' — incorrectly substitutes a post-trial, harmless error inquiry for the inquiry into pre-trial, objective reasonableness mandated by the statute.4 And thereby it fails to protect fully the right created by section 3593(a).
We, however, cannot proceed to dispose of Ferebe’s claim under the proper analytical framework because the lower court, having adopted an incorrect analytical framework, did not clearly address certain necessary elements, without which findings a merits determination would not be appropriate. Consequently, we must vacate the district court’s order and remand the case for further proceedings.
A.
1.
As discussed above, Title 18 Section 3593(a)’s plain language guarantees all who are accused of capital offense the right not to stand trial for their lives unless they have been provided notice a reasonable time before trial that in fact they are to stand trial for their lives.
If, in a case involving an offense described in section 3591, the attorney for the government believes that the circumstances of the offense are such that *731a sentence of death is justified under the chapter, the attorney shall, a reasonable time before the trial or before acceptance by the court of a plea of guilty, sign and file with the court, and serve on the defendant, a notice—
18 U.S.C. § 3593(a) (emphasis added).
The district court, in its merits analysis, did not recognize this feature of the right created by section 3593(a). Nor does the dissent, despite its own conclusion that the section 3593(a) right “is a procedural guarantee that [defendants] will be given adequate time to prepare for a death penalty trial and sentencing.” Post at 746 (emphasis added). But (and this is doubtless the reason for the tension between the dissent’s description of the guarantee and its assertion that there is here no right not to stand trial absent the guaranteed preparation time), it is impossible to identify the right established under section 3593(a), which requires that notice be provided to a defendant before trial, without recognizing that the guarantee is that the defendant “will not be tried for his life without having received a lawful Death Notice.” This statutorily-created right not to be tried for a capital sentence without having received reasonable notice can only be effectuated by an interpretation that the statute imposes a prophylactic requirement which, in turn, necessitates a pretrial inquiry into the objective reasonableness of the notice provided.
The dissent’s contrary conclusion well illustrates why only an objective reasonableness analysis, undertaken pre-trial, adequately protects the right created by the statute. For the dissent’s alternative post-trial prejudice analysis requires capital defendants to risk permanent forfeiture of the right that the statute guarantees them, by forcing them to wait until after trial to learn whether the trials they were required to endure were lawful.
In defending its post-trial, prejudice standard, the dissent, as described above, supra pp. 729-730, offers a wholly self-contradictory formulation of the section 3593(a) right, acknowledging that, on the one hand, section 3593(a) creates a guaranteed “ right to ... a reasonable time to prepare for a death penalty trial and sentencing.” Post at 748 n.l. In that vein, it describes the right as “functioning] to inform” the defendant of the fact that his will be a capital trial and of the grounds for that proposed penalty, as “afford [ing] the defendant an opportunity to prepare his defense,” and as “assuring] that the defendant and the court have notice of the penalty to be sought ... and of [the relevant] aggravating factors.” Post at 746.
But, then, as if actually possessed of a different mind, the dissent asserts that though Ferebe has a guaranteed right that he “will be given adequate time to prepare for a death penalty trial and sentencing,” that guarantee is not a right not to stand trial without that adequate time to prepare for a death penalty trial. See post at 748 (“Indeed ... the statute provides no assurance that a capital trial can be denied if the government fails to produce a timely notice [.]”).
What the dissent gives with one hand— the “guarantee” — it takes back with the other — the denial of a right not to stand for capital trial in the absence of lawful notice. Were the dissent to set its “guarantee” in immediate relief to its conclusion that Ferebe has no right not to stand trial for his life in the absence of a lawful Death Notice, it simply could not avoid the conclusion that we reach: that section 3593(a) guarantees defendants that they will not be tried for their lives without lawful notice.
The analytical incomprehensibility of the dissent’s contrary conclusion is not salvaged by its reliance on other procedural *732rights, which it claims show that rights like the section 3593(a) right are not treated as rights not to stand trial. See post at 746, 747 n.l. None of the rules to which the dissent points establish prerequisites for trial as, by the dissent’s own admission, does section 3593(a). Instead, those rules all simply govern admission of evidence and legal arguments at trial, which, by definition, are only violated when at trial on the merits such are unlawfully admitted. And. of course, a flawed indictment, against which the dissent implies there is also no right not to stand trial, see post 748 n.l, is unappealable collaterally because orders denying challenges to indictments fail to qualify as collateral orders under Abney, not because of an absence of a right not to stand trial under a flawed indictment. A flawed indictment under Abney is unappealable collaterally for the simple reason that it is not “separable from the principal issue at the accused’s impending criminal trial,” Abney, 431 U.S. at 659-60, 97 S.Ct. 2034; it goes directly to the “merits of the charge.” Id.
Because an accused is assured by section 3593(a) that, a reasonable time before trial, he will receive adequate notice that he is to be tried for capital offense, and consequently that he will not be required to stand trial for such offense absent that notice, his rights are denied at the point when he proceeds toward trial, or actually to trial, in the absence of a reasonable time between his receipt of the Death Notice and his capital trial. And this is so, regardless of whether he will or will not be, or was or was not, prejudiced by an unreasonably delayed Death Notice.
The dissent’s interpretation — that if, after trial, it appears that the accused was not in any way prejudiced, then a fortiori he was provided reasonable notice — necessarily leads to the untenable conclusion that the statute would be satisfied if notice were given after trial commenced or, for that matter, never given, provided the accused is not prejudiced thereby (for instance, because he proceeded throughout on the assumption that his was a capital trial).
This analytical point lies at the heart of the divide between our opinion and the dissent’s. The dissent addresses this issue in footnote 3 on page-of its opinion. There it reasons as follows:
If notice is given after trial has commenced, the objection would be that notice was given after trial commenced, not a “reasonable time before trial.” Likewise, if notice is never given, the objection would be that notice was never given.
Post at 750 n.3. This simply cannot be. For, as the dissent itself says, because “Congress [has] not mandate [d] a particular deadline for providing the notice,” post at 746, “the critical determination under § 3593(a) is whether the notice was provided a reasonable time before trial,” post at 746. Having thus explained the section 3593(a) right, any objection raised on the right, whether to late notice before trial, to late notice after trial begins, or to no notice at all, must establish that notice was not provided a reasonable time before trial.
And, under the dissent’s analysis, the reasonable time that notice must be provided before trial could well be never, since the statute provides no “deadline” and prejudice is its sole concern. By way of the dissent’s own contemplation: where a defendant “was able to prepare based on [actual, though not formal] notice,” post at 749, that defendant would suffer no prejudice from lack of a Death Notice, the reasonable amount of notice time the defendant would need to prepare would thus be zero, and the statute would be satisfied.
*733Ultimately, the dissent’s conclusion that the right turns on reasonableness, see post at 746, that reasonableness turns on prejudice, see post at 748, and that prejudice turns on the defendant’s preparation at trial, see id., cannot possibly be understood differently than to require a conclusion that the statute is satisfied in every instance in which there has been no prejudice. For if, as the dissent believes, adequate preparation time is the only concern of the statute and prejudice is the sole determinant of the adequacy of that preparation time, the statute is satisfied upon a finding that the defendant suffered no prejudice, regardless of when notice was given — and even if no notice were ever given.
That under the dissent’s analysis a defendant who objects to the government’s complete failure to provide him a Death Notice, but whose objection is overruled, must undergo trial for his life, conviction, being sentenced to die, and imprisonment on death row before he may appeal the district court’s conclusion that the government’s total failure to provide a Death Notice did not violate section 3593(a) only reinforces the conclusion that no notice could be lawful under the dissent’s analysis and that the dissent’s denial of this result is little more than ipse dixit.
And, were the dissent to suggest that its analysis does not require the conclusion that an order denying a challenge to a death penalty trial for which notice was never given is unappealable collaterally, it would then have to admit that the section 3593(a) right is a right not to stand trial, after all. To do so, however, would require either its forfeiting the entire analysis or relying upon the distinction that section 3593(a) is a right not to stand trial where notice is never given, but is not a right not to stand trial if the notice given is inadequate for the defendant to prepare his defense. As perhaps the dissent senses, such a distinction — that no notice triggers a right not to stand trial, but that late notice does not trigger that same right — -is wholly unconvincing. It fails analytically because both circumstances constitute the same violation — -lack of lawful notice. But also it yields an instinctively unsatisfactory result. It would allow a defendant to bring a collateral appeal if a Death Notice were filed the moment after the judge gavelled the trial’s voir dire to a start, but would not allow such an appeal if that same notice were filed but a moment before the gavel dropped.
That, in the end, these difficulties require the dissent to conclude that defendants who never receive notice that they are to be tried for their life must endure trial, conviction, death sentence, and death row imprisonment before they may appeal the denial of their objection to receiving no notice is but a symptom of the dissent’s analytical error — its denial of the section 3593(a) right’s full import.
The dissent’s analysis also turns in on itself. The multiple factors the dissent goes to length to identify as serving to remedy violations of the statute confirm this. See post at 749. For, under the dissent’s interpretation of section 3593(a), those many factors are actually meaningless. Since ultimately reasonableness is determined by reference to prejudice under the dissent’s analytical framework, those assertedly distinct factors only have relevance insofar as they reveal prejudice.
We cannot embrace an interpretation of section 3593(a) that not only requires a post-trial assessment of prejudice but forbids a pre-trial assessment of the reasonable timeliness of the mandated Death Notice, without at the same time denying to those capital defendants who were provided no Death Notice or a Death Notice an unreasonably short time before their trials, *734the right that is conferred upon them by section 3593(a). Accordingly, we must, and do, adopt the objective assessment of pre-trial reasonableness described fully above.

That a post-trial, actual prejudice standard does not protect the rights created by section 3593(a) is sufficient reason to reject it. But the reasons assumed by the lower court and explained by the dissent in support of such a standard, themselves, also confirm the need for rejection of such a standard.
Both the lower court and the dissent superficially analogize the right created under section 3593(a) to the speedy trial right, and because a post-trial assessment of prejudice is the governing standard in the latter context, they conclude that the same standard should apply under section 3593(a). Upon careful consideration, however, it is plain that this analogy to the speedy trial right does not hold.
To begin with, even a quick comparison of the speedy trial right and the section 3593(a) right reveals that the two are not at all similar in the manners the dissent concludes. The Supreme Court provided a detailed explication of the speedy trial right in Barker v. Wingo, 407 U.S. 514, 92 S.Ct. 2182, 33 L.Ed.2d 101 (1972). There the Court noted that the speedy trial right is unique in that it belongs to both the defendant and society.
The right to a speedy trial is generically different from any of the other rights enshrined in the Constitution for the protection of the accused. In addition to the general concern that all accused persons be treated according to decent and fair procedures, there is a societal interest in providing a speedy trial, which exists separate from, and at times in opposition to, the interests of the accused.
Id. at 519, 92 S.Ct. 2182. See also id. at 519-21, 92 S.Ct. 2182 (noting that several explicit factors create society’s interest in speedy trials, such as the backlog of cases in the courts which, among other things, enables defendants to achieve more attractive plea bargains; the fact that lengthy bond releases allow criminal suspects to commit further crimes; the temptation a lengthy bond release gives to a suspect to jump bond; the detrimental effect delays between trial and arrest have on preservation of evidence and the conduct of fair trials; the detrimental effect a delay in punishment may have on rehabilitation; the deplorable jail conditions that result from overcrowding worsened by those who cannot make bond; the high cost of lengthy pre-trial detention; and the lost wages of pre-trial detainees).
The Court further observed in Barker that violation of the speedy trial right “might work to the accused’s advantage,” id. at 521, 92 S.Ct. 2182, since it belongs to both the defendant and society. It also noted that the right is “a more vague concept than other procedural rights ... [since] [it] cannot definitely [be said] how long is too long in a system where justice is supposed to be swift but deliberate.” Id.
The section 3593(a) right differs from the speedy trial right in every one of these respects. Unlike the speedy trial safeguards, section 3593(a) does not protect any societal interest of the kind referenced by the Court in Barker. To the contrary, this right to notice, like “the other rights enshrined in the Constitution for the protection of the accused,” id., provides a guarantee only to the criminal defendant. Relatedly, it is not even arguable that the enforcement of this right might work to Ferebe’s advantage if the government *735tries him for his life without providing a lawful Death Notice. Nor is it arguable that the section 3593(a) right suffers from the vagueness problem that inheres in rights that simultaneously protect multiple opposing interests.
These differences in characteristics are of no small moment, because it was on the basis of these characteristics that the Supreme Court held that a post-trial prejudice analysis must be applied to speedy trial right claims. See Barker, 407 U.S. at 530, 92 S.Ct. 2182 (reasoning that a balancing test is necessary for proper vindication of the speedy trial right because the right belongs to both the defendant and the society, because violations of the right can benefit the defendant, and because the right is vague by virtue of its belonging to both; and further reasoning that a prejudice inquiry is a necessary part of that balancing test).
Equally unfounded is the dissent’s reliance on United States v. MacDonald, 435 U.S. 850, 98 S.Ct. 1547, 56 L.Ed.2d 18 (1978), which, still by way of analogy to the speedy trial right, it maintains also dictates use of a post-trial prejudice standard to evaluate claims under section 3593(a). MacDonald’s, principal holding was that speedy trial claims can only be evaluated post-trial, and so are not collaterally ap-pealable. The Court based this holding on the fact that Barker governed such claims, and that Barker required a prejudice determination. The Court straightforwardly reasoned that since prejudice could not be determined until post-trial, pre-trial speedy trial claims were speculative, inconclusive, and tied to the merits, and thus were undeserving of Cohen collateral ap-pealability. Insofar as MacDonald simply relied upon Barker’s, prejudice analysis governing the professedly-unique speedy trial right, MacDonald is as inapplicable as is Barker itself.
Not only is MacDonald’s central analysis as inapplicable here as Barker’s for the reasons stated, but MacDonald’s alternative rationale for decision points up a further difference between the speedy trial right and the section 3593(a) right. MacDonald concluded that speedy trial right claims are not collaterally appealable also because the speedy trial right is not a right not to stand trial, thus making post-trial adjudication sufficient for vindication of the right.
Unlike the protection afforded by the Double Jeopardy Clause, the Speedy Trial Clause does not, either on its face or according to the decisions of this Court, encompass a “right not to be tried”.... It is the delay before trial, not the trial itself, that offends. ... If the factors outlined in Barker v. Wingo, combine to deprive an accused of his rights to a speedy trial, that loss, by definition, occurs before trial. Proceeding with the trial does not cause or compound the deprivation already suffered.
MacDonald, 435 U.S. at 861, 98 S.Ct. 1547 (emphasis added). In contrast, section 3593(a), provides defendants a right not to be tried without valid notice. See supra Part II.A.1. And proceeding with the trial most certainly compounds the deprivation.
Finally, the dissent justifies application of a post-trial, prejudice inquiry under section 3593(a) on the ground that the statute might appear to necessitate knowledge of the actual date that trial commences. See, e.g., post at 740-741, 749-750. But even if one were required to know the date that trial actually starts, it does not follow that a posi-trial inquiry is mandated, much less the post-trial prejudice inquiry that the dissent would adopt. That the trial commencement date would have to be known (if that is the case) would require at most that the adjudication of the timeliness of a *736contested Death Notice not occur until the instant the trial actually starts.
3.
Insofar as different, but analogous, rights and their required analyses are instructive, the section 3593(a) right closely resembles the constitutional right not to be tried twice for the same offence, as our discussion of MacDonald confirms. Violations of the latter the Supreme Court has of course never analyzed under a prejudice framework.
Additionally, there is also a powerful analogy between charging instruments (i.e., indictments) and Death Notices. Both protect the fundamental fairness of proceedings at which criminal defendants are called upon to defend themselves. Both serve to set defendants on notice so that they can adequately prepare to defend themselves. Defendants have a right to receive both prior to trial. And violation by the government of those rights, if properly objected to, will invalidate the attendant proceedings. As with Double Jeopardy rights, the Supreme Court has never suggested that where a defendant objects to the unlawfulness of a charging instrument the lawfulness of the charging instrument should be evaluated under a prejudice framework.5
4.
In the final analysis, what must be borne in mind is that the interpretation of 18 U.S.C. § 3593(a) turns not at all on the implications of that interpretation for the separate question of appealability under 28 U.S.C. § 1291, even though the appealability under section 1291 turns dramatically on the interpretation of section 3593(a). It is the complete independence of the interpretive question from the appealability question that the dissent fails to appreciate.
If one understands that these are and must be separate and independent inquiries, then it is clear that whether there is prejudice cannot possibly be determinative of whether the right protected by section 3593(a) was violated. Prejudice in the sense intended by one who would assert that such is determinative of whether a statute has been violated (like the dissent), is akin to harmless error. And, of course, the harmlessness of an error is determined (and necessarily so) only after an antecedent conclusion that there was in fact an error committed. To inform resolution of the question of whether the statute has been violated by a prejudice inquiry is, pure and simple, to confuse the question of harmlessness with the question of violation.
Congress spoke quite clearly in section 3593(a): The government “shall, a reasonable time before the trial or before acceptance by the court of a plea of guilty, sign and file with the court, and serve on the defendant, a [Death Notice].” Because adoption of a post-trial, actual prejudice standard would not fully protect this right created under the statute; because there is no basis on which to analogize between the speedy trial right and this right; and because the Supreme Court has never sug*737gested use of a prejudice inquiry to vindicate those rights that are most analogous to the right found in section 3593(a), we conclude that there is no basis for applying a post-trial, prejudice standard when a violation of section 3593(a) is alleged.
B.
Notwithstanding the dissent’s fundamental disagreement with the court over the proper interpretation of section 3593(a), the first three factors it identifies as informing the inquiry into the reasonableness of the timing of the notice can, roughly, be legitimately encompassed within the objective inquiry that is mandated by the statute. See post at 748-749. To these, at least a fourth must be added. And consideration of still other factors is not foreclosed. To judge an accused’s challenge to the reasonable timeliness of a Death Notice requires evaluation of, among other factors that may appear relevant, (1) the nature of the charges presented in the indictment; (2) the nature of the aggravating factors provided in the Death Notice; (3) the period of time remaining before trial, measured at the instant the Death Notice was filed and irrespective of the filing’s effects;6 and, in addition, (4) the status of discovery in the proceedings. It should be determined on the basis of these factors whether sufficient time exists following notice and before trial for a defendant to prepare his death defense.
C.
In this case, the district court analyzed Ferebe’s section 3593(a) claims under a speedy trial act-type prejudice analysis. See supra note 3. This, as made clear by the above analysis, was error. We, however, cannot simply conduct the merits analysis ourselves to correct the error. For, as a consequence of the district court’s adoption of the incorrect analytical framework, its decision did not sufficiently address necessary elements of the section 3593(a) analysis and thus did not produce certain findings indispensable to our review of the order. As a consequence, we must vacate the challenged order and remand the case to allow the district court to adjudicate the matter under the proper analytical framework.
1.
One of the essential elements that a proper analysis of a motion to strike a Death Notice for violation of section 3593(a)’s timeliness requirement must clearly address is the period of time that remains before trial, as of the moment of the Death Notice’s filing, and irrespective of that filing. See supra p. 736 (the third of the four non-exclusive factors we set *738out for determining the pre-trial objective reasonableness of the timing of a Death Notice). By logical necessity, of course, before a court can assess the objective reasonableness of this interval (i.e., the interval between the Death Notice’s filing and trial), it must first quantify the interval. See supra note 6. If no date of trial is identifiable, then the interval between the date of filing and that yet unknown and unidentified date cannot be measured. And if the interval cannot be measured, then the court cannot reach conclusions, as the statute requires, about the objective reasonableness of that interval.
Here, we are unable to address this third element — the time remaining between the Death Notice’s filing and trial— with respect to Ferebe’s section 3593(a) claim.7 The record does not clearly reveal whether, at the instant the Death Notice was filed, a date existed on which Ferebe’s trial was set to begin. We can discern that a trial date of September 10 had been set by the district court in December of the preceding year and that that trial date was never cancelled on the record by the court. That suggests that a trial date was set. But, the court’s words, recorded at the September 7, 2001 hearing on Ferebe’s motion to strike the Death Notice (the “Motion Argument”) and in its September 12, 2001 oral opinion denying the motion (the “Order”), cast doubt on whether that date in fact remained fixed.
The district court, noting that the parties postponed their June and July pretrial hearings and conferences after the conditional plea agreement was reached in June 2001, suggested that the postponements had the practical effect of cancelling the September 10 trial date. The court’s comments, however, do not establish that the trial start date was cancelled in advance of the Death Notice’s filing and irrespective of it.
In particular, the district court said as follows from the bench:
I think that in looking at issues in both criminal trials and civil trials, you start with the schedule. And the schedule is a reality. It can be worked with in some cases. But if there are notice and other requirements, you start with when is the trial date, where were the notices filed, and you don’t always assume that the trial date is flexible and can be moved.... [T]his trial has to be postponed in any event because once I was advised that Mr. Ferebe had changed his mind or that’s the way things were looking and that the case was going to be worked out, resolved by a plea, the other things got set in and hearing dates that we had scheduled for June and July were taken off the table. So they’ve all not been met and the most crucial one being working up the questionnaire for the jury. I’ve been advised by the jury section that that takes at least six to eight weeks. So that when the jury questionnaire selection dates all slipped, that meant that we were no longer looking at a September trial date. We’re looking at something at least six to eight weeks beyond that.
J.A. at 161 (Motion Argument) (emphasis added). And:
By the time [the Attorney General] made its [July 26] decision [rejecting the conditional plea agreement], the September 10 trial date was irretrievably lost. For one thing, I set in other matters for September tenth.
*739Second, neither counsel for the defense nor counsel for the government, as of the date of the turndown in late July 2001 would have been ready for a trial starting on September the 10th.
But the most crucial aspect as of the late July time period was that we had no jury questionnaire appropriate to a death penalty case. The timetable for drafting, investigating, and approving such a questionnaire from which to pick a qualified death penalty jury, that timetable had slipped because of the decision by the court and counsel to stop work, to stay our oars and see what would happen in Washington.
I have been advised by the jury section that it takes at least eight weeks to go through the process of mailing the death penalty questionnaire, retrieving the responses, reviewing the responses with court and counsel, and bringing into court the qualified jury.
This case must, accordingly, be rescheduled, and any possible prejudice to Mr. Ferebe with respect to the guilt phase or the sentencing phase will be cured by the additional time that defense counsel will have to prepare their case [.]
J.A. at 214-15 (Order) (emphasis added).
The court’s words at the Motion Argument are susceptible to two different interpretations. The court says that the trial was no longer scheduled to start September 10 “when the jury questionnaire selection dates all slipped,” pointing to the parties’ pre-Death Notice conduct as having voided the September 10 trial date as a practical matter. But, the court also indicates, at the same time, that the Death Notice’s filing was itself the but for reason for finding the September 10 trial date to have been practically voided. Thus, the court noted the requirements of proceeding with a capital trial (the result of the Death Notice’s filing) as the hurdles to keeping the September 10 trial date. The former statement supports the conclusion that there was no set trial date at the moment the Death Notice was filed, while the latter supports the conclusion that the September 10 date was set at that moment, but that the court voided it in order to accommodate the capital trial called for by the prosecution’s delinquent Death Notice.
The Order’s language and analysis is not any more precise. The Order says that the “most crucial” factor necessitating a re-scheduling of the trial was the time it would take to construct the jury questionnaire and that that period would be at least eight weeks. This, of course, adds weight to the second interpretation we offer above of the court’s Motion Argument comments. It, too, implies that the trial remained set for September 10, but that the court thought it necessary to re-schedule it in order to accommodate a capital trial.
That the September 10 trial date continued in force at the moment the Death Notice was filed is further suggested by the fact that the district court had in August issued a written query to Ferebe inquiring whether he “would be ready to go to trial on September 10, 2001,” see J.A. at 206 (the Order). Ferebe responded that he “would be ready to go forward with trial on September 10, 2001[,] provided that the trial was a non-death penalty trial.” Id. The query suggests that the court may have had in mind that the September 10 trial date remained in force as late as mid-August.
But, at the same time, the conclusion that the trial was set for September 10 at the moment the Death Notice was filed is undercut by the court’s assertion that the trial date “was irretrievably lost” as a result of the postponement of the June and *740July hearing dates. Id. at 214. This statement directly contradicts our preceding observations and suggests instead that the trial date was lost as a practical matter prior to the Death Notice’s filing and irrespective of whether the death penalty would be under consideration at trial.8
These varied aspects of the district court’s oral statements and the posture of the case make unknowable for us whether at the moment of the Death Notice’s filing, and irrespective of the procedural effect of trying a capital case (which up until that point the trial was not), Ferebe’s trial was set for September 10, for an equivalent date, or for no date at all.
Because we cannot determine whether, at the time of the Death Notice’s filing, a date existed on which Ferebe’s trial was set to start, we cannot complete an evaluation of the merits of Ferebe’s claim. A court necessarily errs where it rules on a motion to strike a Death Notice under section 3593(a)’s timeliness requirement but no trial date is set, or no trial has begun. As explained above, without a date from which to measure the amount of time remaining from the filing to trial, a court cannot reach conclusions as to the objective reasonableness of that yet unknown and unidentified interval.
Thus, we must remand the case to allow the district court to address the motion again, this time under the proper analytical framework and with an eye towards deciding these unaddressed, yet indispensable, factual issues.9
2.
Having determined that the district court applied an incorrect prejudice analysis in its initial adjudication of Ferebe’s motion to strike the Death Notice, and having determined that remand is necessary so as to develop the record further, we vacate the district court’s order denying Ferebe’s motion and remand to that court for further proceedings.
CONCLUSION
The judgment of the district court is vacated and the case is remanded with instructions to proceed consistent with the opinion herein.
VACATED AND REMANDED
. More precisely, Ferebe and his co-defendant were indicted under four provisions of Title 18 of the United States Code: section 924(j)(l) (firearms murder during or in relation to drug trafficking crime); section 924(c) (use and carrying of firearms during and in relation to drug trafficking crime); section 841(a) (conspiracy to distribute cocaine and marijuana); and section 2 (aiding and abetting).
. At this point in the chronology, Ferebe's indictment was more than four years old and the Attorney General’s authorization of the death penalty was more than three and a half-years old.
. The district court, in deciding to deny Fer-ebe's motion to strike the Death Notice, adopted the reasoning of the district court for the District of Puerto Rico, which, like the dissent here, concluded that challenges to Death Notices brought under section 3593(a)'s timeliness provisionought be evaluated under the analytical framework applied to Speedy Trial Act claims. See United States v. Colon-Miranda, 985 F.Supp. 31 (D.P.R.1997) (Death Notice struck for being filed two weeks before trial, though a rescinded version was first filed three months before trial). Said the district court here, “the most important factor is prejudice to Mr. Ferebe.” See J.A. at 211.
. Though the lower court did not claim that its analysis necessitates a posi-trial adjudication of motions to strike Death Notices, the logic of the lower court’s prejudice-based analytical framework, as Judge Niemeyer well explains, unavoidably leads to such a result.
. Not only do the similarities between indictments and Death Notices confirm that prejudice should not be used to analyze violations of the latter, but their differences are consistent with our earlier conclusion that district court orders on Death Notice challenges are collaterally appealable. District court orders upholding challenged indictments are, of course, not collaterally appealable. This is so because indictments are necessarily bound up with the merits of the case. Death Notices, on the other hand, remain separate from the merits question of a defendant's guilt since their “charging” elements only pertain to sentencing.
. To quantify this interval, a court naturally must have reference to two dates: the first, obviously, being the date the Death Notice is filed, and the second, obviously, being the trial date. Less obvious is that the scheduled trial date may constitute the trial date for purposes of analysis under section 3593(a) because of the prophylactic nature of the statutory right.
This latter conclusion is necessitated by the twin facts that the right guarded by section 3593(a) is violated at the time that a defendant is required to proceed to trial for his life with insufficient time to prepare, see supra pp. 731-732, and that, like all rights, with the exception of the unique, speedy trial act right, see supra pp. 733-734, violation of the section 3593(a) right may be vindicated by objection at the moment of the violation. The only other possible analytical framework for vindicating, the section 3593(a) right, one based on an after-the-fact review for prejudice, would allow notice never to be given and the notice requirement still to be satisfied. The statutory language simply does not countenance such a result. And so, we must prefer the pre-trial objective reasonableness analysis, which by its character, for purposes of pretrial Death Notice challenges, references the set trial date as the date of trial.
. Because the district court relied on a prejudice analysis to decide the motion, it did not analyze this element, and, as the discussion below makes clear, its peripheral discussions regarding the time trial was or was not set to begin and the time remaining before trial lack the precision and exactness necessary to the analysis.
. Similarly ambiguous are the district court's subsequent comments that "any possible prejudice to Mr. Ferebe will be cured by the additional time that defense counsel will have to prepare their case[,]” J.A. at 215, as these comments also beg the question of whether . that "additional time" was a result of the fact that the trial date was truly lost (and not lost because of the Death Notice filing), or if it was instead a result of the delay in the trial occasioned by the Death Notice's delinquent filing (i.e., the delays occasioned by the unique requirements of a capital trial, caused by litigation over Ferebe’s objection to the Death Notice, or created by the court to provide additional time for Ferebe to prepare).
. As should be evident from our discussion herein, district courts cannot decide challenges to Death Notices brought under section 3593(a)’s timeliness requirement until they have before them the requisite factual elements. Where they do otherwise, they err.
