These cross-appeals require us to wend our way through a maze of unusual facts and subtly nuanced legal issues. After exploring a little-charted frontier of tort law, we reverse the district court’s direction of judgment notwithstanding the verdict and reinstate the jury’s award on the plaintiffs claim for negligent infliction of emotional distress. In all other respects, we affirm the rulings of the lower court.
I. BACKGROUND
This litigation arises out of the tragic demise of James Blinzler, husband of the plaintiff Gloria Blinzler. The course of events leading to James Blinzler’s death began on November 13, 1992, when the Blinzlers checked into a Somerset, New Jersey, hotel operated by the defendant Marriott International, Inc. (Marriott). Shortly after 8:30 p.m. the decedent, relaxing in his room, experienced difficulty in breathing. Sensing danger, he ingested nitroglycerin (he had suffered heart attacks before) while his wife called the hotel PBX operator and requested an ambulance. The operator received the SOS no later than 8:35 p.m. and agreed to honor it. She promptly told the hotel’s security officer and the manager on duty about the medical emergency. Though the defendant steadfastly maintains that the operator also called an ambulance then and there, the record, read hospitably to the verdict,
see Cumpiano v. Banco Santander P.R.,
When the paramedics arrived on the scene, they could not locate a pulse and discovered that the decedent’s airway was blocked. Re- *1151 suscitative efforts restored the decedent’s heart to a normal rhythm and he was transported celeritously to a nearby hospital. Doctors diagnosed the heart attack as a “very small myocardial infarction.” Nevertheless, the brain damage resulting from a prolonged period of asystole without cardiopulmonary resuscitation led to James Blin-zler’s death three days later.
II. PROCEEDINGS BELOW, ISSUES ON APPEAL, AND RULES OF DECISION
Invoking diversity jurisdiction, 28 U.S.C. § 1332 (1994), the plaintiff sued Marriott in Rhode Island’s federal district court for wrongful death (count 1), loss of consortium (count 2), and negligent infliction of emotional distress (count 3). She alleged in substance that the hotel failed to summon an ambulance in a timely fashion and that this carelessness proximately caused both her own damages and her husband’s death. The jury agreed, awarding $200,000 for wrongful death, $50,000 for loss of consortium, and $200,000 for emotional distress. Addressing a variety of post-trial motions, the district judge upheld the verdict, on the first two counts, but granted judgment for the defendant on the third count. Both sides appeal.
The cross-appeals raise several issues. Two are in the forefront. The centerpiece of the defendant’s appeal is the assertion that the evidence did not forge a causal link between the failure promptly to summon an ambulance and the ensuing death. In contrast, the plaintiffs appeal hinges on the district court’s extirpation of the jury verdict on her claim for negligent infliction of emotional distress. Because the defendant’s contention that the plaintiff failed as a matter of law to prove causation involves an across-the-board challenge to the jury verdict as a whole, we deal first with that issue. We then mull the plaintiffs contention that the lower court erroneously forecast emergent New Jersey law on bystander liability and therefore erred in setting aside the verdict on count 3. Finally, we address the defendant’s remaining assignments of error.
Under the principles of
Erie R.R. Co. v. Tompkins,
In its barest essence, borrowing state law demands nothing more than interpreting and applying the rules of substantive law enunciated by the state’s highest judicial authority, or, on questions to which that tribunal has not responded, making an informed prophecy of what the court would do in the same situation.
1
See Moores v. Greenberg,
III. CAUSATION
The defendant challenges the entire verdict on the basis that the plaintiff provided insufficient evidence from which a reasonable jury could conclude that the belated call constituted a proximate cause of the ensuing death. Under New Jersey law the plaintiff bears the burden of proving that the defendant’s conduct comprised “a substantial factor in producing the harm” of which the plaintiff complains.
Francis v. United Jersey Bank,
One species of omission that occurs from time to time involves the generic charge that, had the defendant done some particular act, the plaintiff (or, as here, the plaintiff’s decedent) would have had a better chance to ward off threatened harm. In these so-called “loss of chance” cases New Jersey law instructs that the plaintiff can carry her burden by showing a “substantial possibility” that the harm would have been averted had the defendant acted in a non-negligent manner.
Hake v. Manchester Township,
Under these authorities, the question here reduces to whether the evidence, viewed in the light most congenial to the plaintiff, supports a finding that the defendant’s failure promptly to call an ambulance negated a substantial possibility that James Blinzler would have survived. We think that this question warrants an affirmative answer.
The plaintiff submitted evidence that she beseeched the defendant to summon help at 8:35 p.m.; that an ambulance crew was available and free to respond at that time; and that the defendant agreed to place the call but then neglected to do so. The defendant actually made the call at 8:49 p.m. (some fourteen minutes later) and the ambulance reached the scene at 9:02 p.m. (an elapsed time of thirteen minutes). The juxy heard opinion evidence from a renowned cardiologist that serious brain damage (and, hence, death) would have been forestalled had the paramedics reached the premises ten minutes earlier. On this record, we believe that a reasonable jury could conclude that the defendant’s omission negated a substantial possibility that the rescue efforts would have succeeded. Put another way, a reasonable jury could find (as this jury apparently did) that the ambulance likely would have arrived fourteen minutes earlier had it been summoned immediately; that the course of treatment would have been accelerated by a like amount of time; and that, but for Marriott’s negligence James Blinzler would have survived.
The defendant tries to parry this thrust in two ways. One initiative involves assembling a string of cases (mostly of hoary origin) in which courts have rejected plaintiffs’ claims of negligence for failure to rescue.
See, e.g., Foss v. Pacific Tel. & Tel. Co.,
This second point is aptly illustrated by the one entry in Marriott’s string citation that does not involve a burning building:
Hardy v. Southwestern Bell Tel. Co.,
Hardy,
fairly read, confirms the distinction between proof of causation in loss of chance cases under the traditional test (to which Oklahoma adheres in cases not involving medical malpractice) and under more modem standards that focus instead on whether a defendant’s conduct has significantly increased particular risks. As we have explained, New Jersey’s “substantial possibility” standard applies to loss of chance cases in general,
3
and it is at a minimum as liberal as the “increased risk” standard endorsed by section 323 of the Restatement.
See Olah,
Marriott’s second attempt to scuttle the finding of causation features its lament that, the plaintiff did not prove that the same traffic conditions which were extant at and after 8:49 p.m. were also extant at and after 8:35 p.m. This lament can scarcely be taken seriously. Juries have the power to draw reasonable inferences from established facts. It is well within a jury’s ordinary competence to conclude that traffic conditions for an emergency vehicle do not change dramatically in a fourteen minute period that is well outside rush hour.
The defendant’s suggestion that a highway accident, or a diluvian tempest, or some other freak occurrence, later abated, might have delayed the ambulance if it began its run at 8:35 p.m. rather than at 8:49 p.m. is equally jejune. It is the plaintiffs burden to prove her ease by a preponderance of the evidence, not beyond all conceivable doubt. In the absence of some reason to suspect changed conditions — and there is no evidence of any actual change here — the jury’s inference that the ambulance would have arrived in roughly the same elapsed portal-to-portal time is unimpugnable.
See Levesque v. Anchor Motor Freight, Inc.,

IV. BYSTANDER LIABILITY
The most vexing issue in this case involves the plaintiffs claim of negligent infliction of emotional distress. This claim is based on the injury that she experienced while watching her husband suffer as the beleaguered couple awaited the ambulance’s overdue arrival. We start this segment of our analysis with a discussion of the doctrine of bystander liability as it has evolved in New Jersey, then shift our attention to an open question that the district court found to be dispositive, and, finally, apply the doctrine as we understand it to the idiosyncratic facts of this case.
A. General Principles of Bystander Liability.
American courts first recognized bystander liability in the landmark case of
Dillon v. Legg,
Twelve years later, New Jersey embraced bystander liability in
Portee v. Jaffee,
In an effort to furnish a condign remedy for deserving injuries while at the same time avoiding “speculative results or punitive liability,”
Portee,
These four elements serve a critical function in keeping bystander liability within reasonable bounds. First, they furnish a set of guideposts that help to identify and define a range of claims that are presumptively valid while excluding other claims that society simply cannot afford to honor.
See Dunphy,
642
*1155
A.2d at 377 (noting that the elements of bystander liability “structure the kind of ‘particularized foreseeability
5
that ensures that the class is winnowed ... and that limitless liability is avoided”). Second — and relatedly — they combine to define narrowly the emotional interest that the law protects.
See Carey,
The common thread that runs through these cases is that emotional anguish is a natural, perhaps omnipresent, reaction whenever one is forced to watch a loved one suffer, and therefore should not be compen-sable in the absence of special circumstances. In an effort to hold the line, New Jersey law decrees that bystanders may recover in tort only' for the particularly exquisite anguish that occurs when they personally observe trauma strike a loved one like a bolt from the blue.
See Frame,
B. The Fork in the Road.
The issue before us is whether the plaintiff’s asserted injury falls within the narrow range of bystander liability claims that are actionable under New Jersey law. The district court decided that it did not. The court relied primarily on a series of bystander liability/medical malpractice cases in which the New Jersey Supreme Court placed a gloss on its earlier decisions and indicated that a plaintiff must witness the actual act of malpractice and appreciate its effect on the patient in order to bring herself within the class of persons entitled to recover.
See Carey,
Here, concededly, Mrs. Blinzler cannot satisfy this added requirement; she neither “witnessed” the negligence (which comprised the hotel operator’s failure immediately to call an ambulance and which occurred six floors beneath the Blinzlers’ room) nor fully appreciated at the time that the negligence was hindering needed assistance (indeed, the defendant’s misrepresentations, if believed, concealed the very fact of the negligence). Thus, to decide this case we must determine whether the Gendek-Carey-Frame gloss applies only to bystander liability/medical malpractice claims (as the plaintiff contends) or whether it applies to all bystander liability claims (as the defendant contends and as the lower court concluded). Although the answer to the question is by no means free from doubt, we think that the district court took the wrong fork in the road.
As an initial matter, the New Jersey Supreme Court has never imposed the added requirement that a plaintiff witness the negligent act and contemporaneously connect it to the injury of a loved one in any case outside the medical malpractice context, and the mal
*1156
practice cases in which the requirement has been imposed strongly suggest that it is restricted to that milieu.
See Gendek,
We note, too, that the added requirement designed by the New Jersey Supreme Court for use in connection with bystander liability/medical malpractice claims is grounded in a set of policy considerations that do not seem to apply to other bystander liability claims. For one thing, the unique emotional interest that fuels the doctrine of bystander liability is unaffected in most cases of medical malpractice for the harm caused by, say, misdiagnosis usually does not manifest itself until days, weeks, months, or years have elapsed, and even then, the misdiagnosis rarely culminates in a single spontaneous and shocking event.
See Frame,
For another thing, the added requirement applicable to bystander liability in the medical malpractice context reflects societal concerns about the impact of expanded liability on the delivery of health care.
See Gendek,
The language of the New Jersey cases and the distinctive nature of the policy considerations that underlie the added requirement mark the genesis of our belief that, when the opportunity arises, the New Jersey Supreme Court will not engraft this health-care-specific requirement upon the body of cases that lie beyond the medical malpractice arena. New Jersey has already expressed its view of general public policy concerns with respect to expanded liability for run-of-the-mine accidents by conferring a right of recovery on bystanders and defining the elements of the tort.
See Dunphy,
C. Applying the Principles.
Once we put the added requirement to one side, the only question that remains open under this rubric is whether the jury lacked evidence satisfactory to support a finding that the plaintiffs injury fell within the standard parameters of bystander liability that obtain in New Jersey vis-a-vis suits arising outside the medical malpractice context. We think the evidence sufficed. Intimate relationship and third-party injury (i.e., a spouse’s death) are not in dispute, and the record contains adequate proof of severe emotional distress. The seminal New Jersey case suggests that, in addition to these three elements, a plaintiff need only show that she “observ[ed] the death ... while it oc-eur[red].”
Portee,
We appreciate that things are not always what they seem and that it may be overly simplistic to say that in New Jersey firsthand observation of a suddenly inflicted injury to a loved one invariably gives rise to the unique emotional interest that underlies bystander liability. Arguably, it is not merely the observation of the injury but the perception that it is accidental or otherwise unwarranted that threatens a “plaintiffs basic emotional security,”
Portee,
Everyone is subject to injury, disease, and death. Common experience teaches that the injury or death of one member of a family often produces severe emotional distress in another family member. A threshold problem is separating the grief that attends that distress when no one is at fault from the added stress attributable to the fact that the injury or death was produced by the negligent act of another.
Id.
at 677. And while the
Portee
elements have not yet been formally modified in this respect,
5
we think it is not unlikely that New Jersey will move in this direction.
Cf. Thing,
1. The evidence here clearly satisfies the
Portee
requirements simpliciter. The plaintiff witnessed a sudden and shocking event when she watched her husband of forty-two years undergo excruciating chest pain, vomit, struggle to catch his breath, asphyxiate, lose consciousness, and ultimately die. Because she “witness[ed] the victim when the injury [was] inflicted,”
Frame,
2. The law of the case doctrine eliminates any potential problem as to the precise dimensions of
Portee.
At trial’s end, the district court charged the jury that “the plaintiff must be present at the scene of the event
*1158
and be aware that the victim is being injured.” The defendant’s counsel objected generally to the court’s decision to instruct the jury at all on count 3 (asseverating that New Jersey law requires the plaintiff actually to witness the negligent act) but he did not object in any other, more specific respect to the district court’s formulation of the basic elements of the tort. Thus, even if New Jersey might in an appropriate ease impose some intermediate limitation going beyond
Portee
but stopping short of mandating that the plaintiff witness the negligent act, the defense formulated no such intermediate position at the jury-instruction stage. In other words, the content of the instruction stands as the law of the case with respect to the unembellished contours of a cause of action for bystander liability.
See Quinones-Pacheco v. American Airlines, Inc.,
Even if we assume
arguendo
that the New Jersey Supreme Court would augment the elements of a non-medieal-malpractiee cause of action for bystander liability along the lines exemplified by
Thing,
the verdict might well be sustainable. From the evidence adduced at trial, the jury rationally could find that during the incident proper the plaintiff
twice
asked the manager whether the ambulance had been called. Though she was (erroneously) assured that the call had been made punctually, she asked the manager yet again at the hospital (receiving the same misinformation), and then checked with the hotel three days later (after her husband had perished). This type of evidence arguably could support an illation that the plaintiff suspected all along that a delay attributable to the defendant was causing injury to her husband. Watching the event while suspecting that her husband’s suffering was being unnecessarily prolonged and worrying that prospects for his rescue were diminishing would appear to be the kind of distinct emotional harm for which bystander liability would lie under the premise of
Thing. See, e.g., Bloom v. DuBois Regional Med. Ctr.,
V. OTHER ISSUES
The defendant raises a salmagundi of other issues in connection with its appeal. None of its asseverations is persuasive. Only three warrant discussion.
A. The Evidentiary Rulings.
The defendant argues that it is entitled to a new trial because the district court erred in certain evidentiary rulings. Its chief complaint concerns the admission of evidence relating to the destruction of the so-called Xeta report (a printout that catalogues all outgoing calls from the hotel’s PBX operator) for November 13, 1992. The defendant destroyed this telephone log approximately thirty days after the incident. Had the report been preserved, it would have pinpointed the very moment that the operator first placed the call for emergency assistance.
During the trial, the plaintiff sought to show that the defendant had destroyed this evidence. The defendant objected, contending that it discarded the Xeta report in the ordinary course of business, pursuant to established practice, and not as part of an effort to inter unfavorable evidence. The district court overruled the objection and permitted the plaintiff to introduce evidence at trial of the existence and subsequent destruction of the Xeta report, leaving the defendant’s explanation to the jury. We review the district court’s rulings admitting or excluding evidence for abuse of discretion.
See Veranda Beach Club Ltd. Partnership v. Western Sur. Co.,
When a document relevant to an issue in a case is destroyed, the trier of fact sometimes may infer that the party who obliterated it did so out of a realization that the contents were unfavorable.
See Nationwide Check Corp. v. Forest Hills Distributors, Inc.,
In this case, the defendant contends that there was no direct evidence to show that it discarded the Xeta report for any ulterior reason. This is true as far as it goes — but it does not go very far. The proponent of a “missing document” inference need not offer direct evidence of a coverup to set the stage for the adverse inference. Circumstantial evidence will suffice.
See, e.g., Brown & Williamson Tobacco Corp. v. Jacobson,
We do not believe that the district court abused its considerable discretion in deciding that the totality of the circumstances here rendered such an inference plausible. A reasonable factfinder could easily conclude that Marriott was on notice all along that the Xeta report for November 13, 1992 was relevant to likely litigation. Although no suit had yet been begun when the defendant destroyed the document, it knew of both James Blinzler’s death and the plaintiffs persistent attempts — including at least one attempt after Blinzler died — to discover when the call for emergency aid had been placed. This knowledge gave the defendant ample reason to preserve the report in anticipation of a legal action. When the evidence indicates that a party is aware of circumstances that are likely to give rise to future litigation and yet destroys potentially relevant records without particularized inquiry, a factfinder may reasonably infer that the party probably did so because the records would harm its case.
See Vodusek v. Bayliner Marine Corp.,
The, defendant also chastises the court for admitting evidence of another missing record. The security officer’s log for November 13, 1992 could not be located, and the judge permitted evidence of that fact to go to the jury. Once again, the ruling camiot be faulted. The defendant had no good explanation for the missing log, and the jury was entitled to infer that the defendant destroyed it in bad faith.
To cinch matters, these two pieces of evidence had a synergistic effect. We think it would be proper for a reasonable factfinder to conclude that the unavailability of two important documents, both of which bore upon the timing of the call for emergency assistance, was something more than a coincidence. The veteran district judge, after hearing all the evidence limning these mysterious disappearances, put it bluntly in the course of ruling on post-trial motions:
I will tell you now that the Xeta Report raises a compelling inference in my mind that personnel at the Marriott Hotel did destroy that record willfully, along with the security officer’s daily log of that date. The inference is compelling that the Marriott Hotel was hiding the delay of the telephone operator in making this telephone call.
This is a harsh assessment — but it is based on a firsthand appraisal of the testimony and it is one that a rational jury easily could draw on the record.
B. The Motion to Reopen.
After the plaintiff rested, the defendant moved for a directed verdict under Fed.R.Civ.P. 50(a). After hearing arguments, the district court permitted the plaintiff to reopen her ease in order to offer certain addi *1160 tional evidence on the issue of causation. 6 The defendant assigns error to this ruling. There is none.
The Federal Rules of Evidence give the district court broad discretion in ordering the proof.
See
Fed.R.Evid. 611. This discretion extends to granting or denying motions to reopen,
see Zenith Radio Corp. v. Hazeltine Research, Inc.,
A trial court’s decision to reopen is premised upon criteria that are flexible and fact-specific, but fairness is the key criterion.
See Rivera-Flores,
Here, the additional evidence that the plaintiff sought to introduce was noncumulative. It had significant probative value on an essential element in the plaintiffs case, helping to connect the defendant’s negligence to the injuries claimed. See supra note 6. There is no sign that the plaintiff withheld the proof as a strategic matter. To the contrary, the record shows quite clearly that she attempted to streamline her case in chief and offered the incremental evidence only after the judge expressed reservations about the state of the proof on the issue of causation. 7
Notwithstanding these circumstances, the defendant insists that permitting the plaintiff to reopen worked substantial prejudice because the defense hoped all along that the plaintiff would fail to prove causation. This is disappointment rather than cognizable prejudice. The evidence taken after reopening consisted of only two witnesses and created no unfair surprise. The added testimony simply fleshed out the plaintiffs basic theory of liability — that the time saved by a prompt call might well have led to James Blinzler’s survival. Moreover, allowing the plaintiff to reopen did not perceptibly delay the trial and did not occasion any interruption of the defense case. In any event, the district court prudently offered the defendant a continuance so that it might regroup and better rebut the additional evidence. By declining the court’s offer, the defendant confirmed the absence of unfair prejudice.
See United States v. Diaz-Villafane,
C. The Emotional Distress Award.
Where, as here, a federal court sets aside a jury’s verdict and directs the entry of judgment as a matter of law, the court must also rule conditionally on any concomitant motion for a new trial. See Fed.R.Civ.P. 50(c). In this instance the district court held that, if it had erred in granting judgment as a matter of law on count 3, then the jury’s award of damages for emotional distress should stand. The defendant assails this contingent ruling and argues for either a new trial or a remitti-tur on count 3. In its most cogent aspect, the argument is based on the premise that the scanty physical symptoms exhibited by the plaintiff simply do not justify an award of $200,000 in damages.
Federal law governs the question of whether the trial court should order a remittitur in a diversity case.
See Donovan v. Penn Shipping Co.,
An award of damages will not be deemed unreasonably high or low as long as it comports with some “rational appraisal or estimate of the damages that could be based on the evidence before the jury.”
Milone,
Here, viewing the evidence of damages in the light most amiable to the plaintiff,
see Toucet v. Maritime Overseas Corp.,
Of course, the task of valuing noneconomic losses in tort eases is an imprecise exercise. There is no one “correct” sum, but, rather, a range of acceptable awards. In many instances the spread between the high and low
*1162
ends of the range will be great. The choice within the range — which by its nature requires the decisionmaker to translate intangibles (such as pain and suffering) into quantifiable dollars and cents — is a choice largely within the jury’s ken.
See Correa,
VI. CONCLUSION
We need go no further. The record adequately supports the jury’s conclusion that the defendant’s inexplicable delay in calling an ambulance constituted a proximate cause of James Blinzler’s death and negligently inflicted both emotional distress and a loss of consortium on his wife (now his widow). Finding, as we do, that the law of New Jersey permits this multifaceted conclusion to remain fully intact, that the defendant’s several challenges to evidentiary and case-management rulings are meriüess, and that the damages awarded are not grossly excessive, we reinstate the jury verdict in its entirety. As a necessary corollary, we vacate the district court’s entry of judgment for the defendant on count 3.
Affirmed in part and reversed in part. Costs in favor of the plaintiff.
Notes
. Indeed, this kind of predictive approach is among our conceptions of law itself. See Oliver Wendell Holmes, The Path of the Law, 10 Harv. L.Rev. 457, 461 (1897) ("The prophecies of what the courts will do in fact, and nothing more pretentious, are what I mean by law.").
. It is commonly thought that the "substantial possibility” standard is more lenient than a standard that requires a plaintiff to prove it is more likely than not that a defendant’s failure to act constituted a substantial factor in bringing about the victim’s injury or death. See. W. Page Keeton et al., Prosser & Keeton on Torts § 41, at 44 (Supp.1988).
. Like Oklahoma, New Jersey has explicitly adopted section 323 of the Restatement for use in loss of chance cases involving medical malpractice.
See Scafidi v. Seiler,
. New Jersey is not alone in its reluctance blindly to follow Dillon's lead.
See, e.g., D’Ambra v. United States,
. In Portee, the question was not raised squarely. There the plaintiff (the victim’s mother) arrived at the scene after her son became trapped in an elevator. She did not witness either the initial entrapment or the act of negligence (faulty maintenance) that caused the accident. It was quite clear, however, that the mother knew immediately that her child’s injuries had an unnatural cause and stemmed from the elevator's accidental collapse.
. The supplemental evidence consisted of testimony from two witnesses. The first, plaintiff's medical expert, simply clarified and confirmed his earlier testimony that James Blinzler would have survived had the ambulance arrived ten minutes earlier. The second witness (an employee of the ambulance service) testified that the ambulance service had a unit ready, available, and on call at 8:35 p.m. on November 13, 1992.
. This is consistent with the method of the Civil Rules. Rule 50(a) exists in part to afford the responding party "an opportunity to cure any deficiency in that party’s proof that may have been overlooked until called to the party’s attention by a late motion for judgment.” Fed.R.Civ.P. 50, advisory committee’s note (1991 amendment). In other words, Rule 50(a) should be construed “to avoid tactical victories at the expense of substantive interests.” Moore, supra, ¶ 50.08, at 50-89 The district court echoed this sentiment when it granted the motion to reopen, stating: "I allow the plaintiff to reopen because I want the truth. I want the facts. I want to achieve a just result in this case....”
. At one time New Jersey courts did require proof of "substantial bodily injury or sickness” in all emotional distress cases.
See, e.g., Caputzal v. The Lindsay Co.,
