Rule 37(e): Failure to Make Disclosures or Cooperate in Discovery; Sanctions.
(e) Failure to Preserve Electronically Stored Information.
Absent exceptional circumstances, a court may not impose sanctions under these rules on a party for failing to provide electronically stored information lost as a result of the routine, good faith operation of an electronic information system. If electronically stored information that should have been preserved in the anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it, and it cannot be restored or replaced through additional discovery, the court:
(1) upon finding prejudice to another party from loss of the information, may order measures no greater than necessary to cure the prejudice; or
(2) only upon finding that the party acted with the intent to deprive another party of the information’s use in the litigation may:
(A) presume that the lost information was unfavorable to the party;
(B) instruct the jury that it may or must presume the information was unfavorable to the party; or
(C) dismiss the action or enter a default judgment.
2015 Rules Committee Commentary to Rule 37(e)
Subdivision (e). Present Rule 37(e), adopted in 2006, provides: “Absent exceptional circumstances, a court may not impose sanctions under these rules on a party for failing to provide electronically stored information lost as a result of the routine, good-faith operation of an electronic information system.” This limited rule has not adequately addressed the serious problems resulting from the continued exponential growth in the volume of such information. Federal circuits have established significantly different standards for imposing sanctions or curative measures on parties who fail to preserve electronically stored information. These developments have caused litigants to expend excessive effort and money on preservation in order to avoid the risk of severe sanctions if a court finds they did not do enough.
New Rule 37(e) replaces the 2006 rule. It authorizes and specifies measures a court may employ if information that should have been preserved is lost, and specifies the findings necessary to justify these measures. It therefore forecloses reliance on inherent authority or state law to determine when certain measures should be used. The rule does not affect the validity of an independent tort claim for FEDERAL RULES OF CIVIL PROCEDURE 39 spoliation if state law applies in a case and authorizes the claim.
The new rule applies only to electronically stored information, also the focus of the 2006 rule. It applies only when such information is lost. Because electronically stored information often exists in multiple locations, loss from one source may often be harmless when substitute information can be found elsewhere. The new rule applies only if the lost information should have been preserved in the anticipation or conduct of litigation and the party failed to take reasonable steps to preserve it. Many court decisions hold that potential litigants have a duty to preserve relevant information when litigation is reasonably foreseeable. Rule 37(e) is based on this common-law duty; it does not attempt to create a new duty to preserve. The rule does not apply when information is lost before a duty to preserve arises.
In applying the rule, a court may need to decide whether and when a duty to preserve arose. Courts should consider the extent to which a party was on notice that litigation was likely and that the information would be relevant. A variety of events may alert a party to the prospect of litigation. Often these events provide only limited information about that prospective litigation, however, so that the scope of information that should be preserved may remain uncertain. It is important not to be blinded to this reality by hindsight arising from familiarity with an action as it is actually filed.
Although the rule focuses on the common-law obligation to preserve in the anticipation or conduct of litigation, courts may sometimes consider whether there was an independent requirement that the lost information be preserved. Such requirements arise from many sources — statutes, administrative regulations, an order in another case, or a party’s own information-retention protocols. The court should be sensitive, however, to the fact that such independent preservation requirements may be addressed to a wide variety of concerns unrelated to the current litigation. The fact that a party had an independent obligation to preserve information does not necessarily mean that it had such a duty with respect to the litigation, and the fact that the party failed to observe some other preservation obligation does not itself prove that its efforts to preserve were not reasonable with respect to a particular case.
The duty to preserve may in some instances be triggered or clarified by a court order in the case. Preservation orders may become more common, in part because Rules 16(b)(3)(B)(iii) and 26(f)(3)(C) are amended to encourage discovery plans and orders that address preservation. Once litigation has commenced, if the parties cannot reach agreement about preservation issues, promptly seeking judicial guidance about the extent of reasonable preservation may be important.
The rule applies only if the information was lost because the party failed to take reasonable steps to preserve the information. Due to the ever-increasing volume of electronically stored information and the multitude of devices that generate such information, perfection in preserving all relevant electronically stored information is often impossible. As under the current rule, the routine, good-faith operation of an electronic information system would be a relevant factor for the court to consider in evaluating whether a party failed to take reasonable steps to preserve lost information, although the prospect of litigation may call for reasonable steps to preserve information by intervening in that routine operation. This rule recognizes that “reasonable steps” to preserve suffice; it does not call for perfection. The court should be sensitive to the party’s sophistication with regard to litigation in evaluating preservation efforts; some litigants, particularly individual litigants, may be less familiar with preservation obligations than others who have considerable experience in litigation.
Because the rule calls only for reasonable steps to preserve, it is inapplicable when the loss of information occurs despite the party’s reasonable steps to preserve. For example, the information may not be in the party’s control. Or information the party has preserved may be destroyed by events outside the party’s control — the computer room may be flooded, a “cloud” service may fail, a malign software attack may disrupt a storage system, and so on. Courts may, however, need to assess the extent to which a party knew of and protected against such risks.
Another factor in evaluating the reasonableness of preservation efforts is proportionality. The court should be sensitive to party resources; aggressive preservation efforts can be extremely costly, and parties (including governmental parties) may have limited staff and resources to devote to those efforts. A party may act reasonably by choosing a less costly form of information preservation, if it is substantially as effective as more costly forms. It is important that counsel become familiar with their clients’ information systems and digital data — including social media — to address these issues. A party urging that preservation requests are disproportionate may need to provide specifics about these matters in order to enable meaningful discussion of the appropriate preservation regime.
When a party fails to take reasonable steps to preserve electronically stored information that should have been preserved in the anticipation or conduct of litigation, and the information is lost as a result, Rule 37(e) directs that the initial focus should be on whether the lost information can be restored or replaced through additional discovery. Nothing in the rule limits the court’s powers under Rules 16 and 26 to authorize additional discovery. Orders under Rule 26(b)(2)(B) regarding discovery from sources that would ordinarily be considered inaccessible or under Rule 26(c)(1)(B) on allocation of expenses may be pertinent to solving such problems. If the information is restored or replaced, no further measures should be taken. At the same time, it is important to emphasize that efforts to restore or replace lost information through discovery should be proportional to the apparent importance of the lost information to claims or defenses in the litigation. For example, substantial measures should not be employed to restore or replace information that is marginally relevant or duplicative.
Subdivision (e)(1). This subdivision applies only if information should have been preserved in the anticipation or conduct of litigation, a party failed to take reasonable steps to preserve the information, information was lost as a result, and the information could not be restored or replaced by additional discovery. In addition, a court may resort to (e)(1) measures only “upon finding prejudice to another party from loss of the information.” An evaluation of prejudice from the loss of information necessarily includes an evaluation of the information’s importance in the litigation.
The rule does not place a burden of proving or disproving prejudice on one party or the other. Determining the content of lost information may be a difficult task in some cases, and placing the burden of proving prejudice on the party that did not lose the information may be unfair. In other situations, however, the content of the lost information may be fairly evident, the information may appear to be unimportant, or the abundance of preserved information may appear sufficient to meet the needs of all parties. Requiring the party seeking curative measures to prove prejudice may be reasonable in such situations. The rule leaves judges with discretion to determine how best to assess prejudice in particular cases.
Once a finding of prejudice is made, the court is authorized to employ measures “no greater than necessary to cure the prejudice.” The range of such measures is quite broad if they are necessary for this purpose. There is no all-purpose hierarchy of the severity of various measures; the severity of given measures must be calibrated in terms of their effect on the particular case. But authority to order measures no greater than necessary to cure prejudice does not require the court to adopt measures to cure every possible prejudicial effect. Much is entrusted to the court’s discretion.
In an appropriate case, it may be that serious measures are necessary to cure prejudice found by the court, such as forbidding the party that failed to preserve information from putting on certain evidence, permitting the parties to present evidence and argument to the jury regarding the loss of information, or giving the jury instructions to assist in its evaluation of such evidence or argument, other than instructions to which subdivision (e)(2) applies. Care must be taken, however, to ensure that curative measures under subdivision (e)(1) do not have the effect of measures that are permitted under subdivision (e)(2) only on a finding of intent to deprive another party of the lost information’s use in the litigation. An example of an inappropriate (e)(1) measure might be an order striking pleadings related to, or precluding a party from offering any evidence in support of, the central or only claim or defense in the case. On the other hand, it may be appropriate to exclude a specific item of evidence to offset prejudice caused by failure to preserve other evidence that might contradict the excluded item of evidence.
Subdivision (e)(2). This subdivision authorizes courts to use specified and very severe measures to address or deter failures to preserve electronically stored information, but only on finding that the party that lost the information acted with the intent to deprive another party of the information’s use in the litigation. It is designed to provide a uniform standard in federal court for use of these serious measures when addressing failure to preserve electronically stored information. It rejects cases such as Residential Funding Corp. v. DeGeorge Financial Corp., 306 F.3d 99 (2d Cir. 2002), that authorize the giving of adverse-inference instructions on a finding of negligence or gross negligence.
Adverse-inference instructions were developed on the premise that a party’s intentional loss or destruction of evidence to prevent its use in litigation gives rise to a reasonable inference that the evidence was unfavorable to the party responsible for loss or destruction of the evidence. Negligent or even grossly negligent behavior does not logically support that inference. Information lost through negligence may have been favorable to either party, including the party that lost it, and inferring that it was unfavorable to that party may tip the balance at trial in ways the lost information never would have. The better rule for the negligent or grossly negligent loss of electronically stored information is to preserve a broad range of measures to cure prejudice caused by its loss, but to limit the most severe measures to instances of intentional loss or destruction.
Similar reasons apply to limiting the court’s authority to presume or infer that the lost information was unfavorable to the party who lost it when ruling on a pretrial motion or presiding at a bench trial. Subdivision (e)(2) limits the ability of courts to draw adverse inferences based on the loss of information in these circumstances, permitting them only when a court finds that the information was lost with the intent to prevent its use in litigation.
Subdivision (e)(2) applies to jury instructions that permit or require the jury to presume or infer that lost information was unfavorable to the party that lost it. Thus, it covers any instruction that directs or permits the jury to infer from the loss of information that it was in fact unfavorable to the party that lost it. The subdivision does not apply to jury instructions that do not involve such an inference. For example, subdivision (e)(2) would not prohibit a court from allowing the parties to present evidence to the jury concerning the loss and likely relevance of information and instructing the jury that it may consider that evidence, along with all the other evidence in the case, in making its decision. These measures, which would not involve instructing a jury it may draw an adverse inference from loss of information, would be available under subdivision (e)(1) if no greater than necessary to cure prejudice. In addition, subdivision (e)(2) does not limit the discretion of courts to give traditional missing evidence instructions based on a party’s failure to present evidence it has in its possession at the time of trial.
Subdivision (e)(2) requires a finding that the party acted with the intent to deprive another party of the information’s use in the litigation. This finding may be made by the court when ruling on a pretrial motion, when presiding at a bench trial, or when deciding whether to give an adverse inference instruction at trial. If a court were to conclude that the intent finding should be made by a jury, the court’s instruction should make clear that the jury may infer from the loss of the information that it was unfavorable to the party that lost it only if the jury first finds that the party acted with the intent to deprive another party of the information’s use in the litigation. If the jury does not make this finding, it may not infer from the loss that the information was unfavorable to the party that lost it.
Subdivision (e)(2) does not include a requirement that the court find prejudice to the party deprived of the information. This is because the finding of intent required by the subdivision can support not only an inference that the lost information was unfavorable to the party that intentionally destroyed it, but also an inference that the opposing party was prejudiced by the loss of information that would have favored its position. Subdivision (e)(2) does not require any further finding of prejudice.
Courts should exercise caution, however, in using the measures specified in (e)(2). Finding an intent to deprive another party of the lost information’s use in the litigation does not require a court to adopt any of the measures listed in subdivision (e)(2). The remedy should fit the wrong, and the severe measures authorized by this subdivision should not be used when the information lost was relatively unimportant or lesser measures such as those specified in subdivision (e)(1) would be sufficient to redress the loss.
2006 Rules Committee Commentary to Rule 37(e) (originally (f))
Subdivision (f). Subdivision (f) is new. It focuses on a distinctive feature of computer operations, the routine alteration and deletion of information that attends ordinary use. Many steps essential to computer operation may alter or destroy information, for reasons that have nothing to do with how that information might relate to litigation. As a result, the ordinary operation of computer systems creates a risk that a party may lose potentially discoverable information without culpable conduct on its part. Under Rule 37(f), absent exceptional circumstances, sanctions cannot be imposed for loss of electronically stored information resulting from the routine, good-faith operation of an electronic information system.
Rule 37(f) applies only to information lost due to the “routine operation of an electronic information system” — the ways in which such systems are generally designed, programmed, and implemented to meet the party’s technical and business needs. The “routine operation” of computer systems includes the alteration and overwriting of information, often without the operator’s specific direction or awareness, a feature with no direct counterpart in hard-copy documents. Such features are essential to the operation of electronic information systems.
Rule 37(f) applies to information lost due to the routine operation of an information system only if the operation was in good faith. Good faith in the routine operation of an information system may involve a party’s intervention to modify or suspend certain features of that routine operation to prevent the loss of information, if that information is subject to a preservation obligation. A preservation obligation may arise from many sources, including common law, statutes, regulations, or a court order in the case. The good faith requirement of Rule 37(f) means that a party is not permitted to exploit the routine operation of an information system to thwart discovery obligations by allowing that operation to continue in order to destroy specific stored information that it is required to preserve. When a party is under a duty to preserve information because of pending or reasonably anticipated litigation, intervention in the routine operation of an information system is one aspect of what is often called a “litigation hold.” Among the factors that bear on a party’s good faith in the routine operation of an information system are the steps the party took to comply with a court order in the case or party agreement requiring preservation of specific electronically stored information.
Whether good faith would call for steps to prevent the loss of information on sources that the party believes are not reasonably accessible under Rule 26(b)(2) depends on the circumstances of each case. One factor is whether the party reasonably believes that the information on such sources is likely to be discoverable and not available from reasonably accessible sources.
The protection provided by Rule 37(f) applies only to sanctions “under these rules.” It does not affect other sources of authority to impose sanctions or rules of professional responsibility.
This rule restricts the imposition of “sanctions.” It does not prevent a court from making the kinds of adjustments frequently used in managing discovery if a party is unable to provide relevant responsive information. For example, a court could order the responding party to produce an additional witness for deposition, respond to additional interrogatories, or make similar attempts to provide substitutes or alternatives for some or all of the lost information.
