Spoliation of evidence in civil litigation involves the loss, destruction, or alteration of relevant electronic or physical evidence. This article explains preservation duties, Rule 37(e) sanctions, prejudice and intent requirements, key court decisions, and how digital forensics and engineering experts evaluate missing evidence, reconstruction limitations, and Rule 702 reliability.
Spoliation of evidence can affect civil litigation when relevant documents, electronic records, or physical materials are destroyed, altered, or lost before they can be examined. The consequences depend on the governing law, when the duty to preserve arose, how the evidence was lost, and whether the requested remedy requires a finding of prejudice or intent to deprive.
In federal civil litigation, Federal Rule of Civil Procedure 37(e) governs certain failures to preserve electronically stored information (ESI), while other legal standards may apply to physical evidence. Courts may impose corrective measures or sanctions when the applicable requirements are satisfied.
This guide explains when preservation duties arise, how courts evaluate spoliation and sanctions, and how qualified experts assess missing evidence and its effect on technical findings.
In civil litigation, spoliation generally refers to the destruction, material alteration, or failure to preserve relevant evidence when an applicable duty to preserve exists.
Once a preservation duty applies, conduct that may raise spoliation concerns includes:
Deleting relevant emails, text messages, or electronic records.
Disposing of damaged vehicles, machinery, or product components before examination.
Overwriting surveillance footage after a preservation obligation arises.
Altering documents or physical materials that may be relevant to a dispute.
Allowing automated systems to delete information that should have been preserved.
However, missing evidence does not automatically establish sanctionable spoliation. Courts consider the preservation duty, the circumstances of the loss, and the legal requirements for the requested remedy.

Allowing automated systems to delete information that should have been preserved.
However, missing evidence does not automatically establish sanctionable spoliation. Courts consider the preservation duty, the circumstances of the loss, and the legal requirements for the requested remedy.
The duty to preserve evidence generally arises when litigation is pending or reasonably anticipated, including before a lawsuit is filed.
In Silvestri v. General Motors Corp., 271 F.3d 583 (4th Cir. 2001), the Fourth Circuit explained that a party may have a preservation duty when it reasonably should recognize evidence's relevance to anticipated litigation.
Depending on the circumstances, potential triggers include:
An incident that makes litigation reasonably foreseeable.
Receipt of a preservation demand or notice of a potential claim.
Communications indicating that legal action is likely.
An investigation revealing circumstances that make litigation reasonably anticipated.
A pending lawsuit or court preservation order.
The scope of preservation depends on the anticipated dispute and the evidence reasonably understood to be relevant.
For ESI, the 2015 Advisory Committee Notes to Rule 37(e) explain that preservation steps must be reasonable, with proportionality among the factors courts consider. The rule does not require perfect preservation of all potentially available information.
Federal courts distinguish between lost electronically stored information and physical evidence when evaluating spoliation. The governing framework affects the findings necessary for corrective measures or sanctions.
Federal Rule of Civil Procedure 37(e) applies when electronically stored information that should have been preserved in anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it, and the information cannot be restored or replaced through additional discovery.
The rule also limits reliance on inherent authority or state law to impose alternative sanctions for ESI loss within its scope.
Rule 37(e) does not govern the destruction of tangible objects such as vehicles, machinery, or construction components.
Federal courts may address physical evidence spoliation through their inherent authority or other applicable procedural rules. For example, Federal Rule of Civil Procedure 37(b)(2) authorizes sanctions for qualifying failures to comply with discovery orders.
The required findings depend on the jurisdiction and the legal authority governing the dispute. Courts may examine the responsible party's conduct, the importance of the missing evidence, prejudice, and whether a less severe remedy would adequately address the problem.
State court proceedings may involve different procedural rules and spoliation standards.
Courts may impose measures ranging from limited corrective relief to dismissal or default judgment, depending on the governing authority and required findings.
For lost ESI, Rule 37(e) establishes different requirements for curative measures and severe sanctions.
Rule 37(e)(1) permits measures to address prejudice caused by lost ESI when the rule's threshold requirements are satisfied.
The court must find prejudice to another party, and the measures ordered cannot exceed what is necessary to cure that prejudice.
Courts may authorize additional discovery under other applicable procedural rules to investigate or replace missing information. When Rule 37(e)(1) applies, appropriate curative measures may include permitting evidence and argument concerning the loss.
Such measures cannot be used to impose the adverse-presumption sanctions reserved for Rule 37(e)(2).
Rule 37(e)(2) permits more serious consequences only when the court finds that a party acted with the intent to deprive another party of the information's use in litigation.
The authorized measures include:
Presuming that the lost information was unfavorable to the responsible party.
Instructing the jury that it may or must presume the information was unfavorable.
Dismissing the action or entering default judgment.
Negligence or gross negligence alone does not satisfy the intent requirement.
Once the rule's threshold conditions and intent requirement are established, Rule 37(e)(2) does not require a separate finding of prejudice. Nevertheless, severe sanctions remain discretionary rather than automatic.
In Silvestri v. General Motors Corp., 271 F.3d 583 (4th Cir. 2001), the plaintiff alleged that the vehicle's failure to deploy its airbag during a collision reflected a product defect.
Although the plaintiff did not own the vehicle, his representatives had access to it and anticipated litigation against General Motors. The vehicle was subsequently repaired by another party without General Motors receiving timely notice or an opportunity to inspect its original post-accident condition.
In those exceptional circumstances, the Fourth Circuit affirmed dismissal because the loss caused extraordinary prejudice to General Motors' defense and lesser sanctions could not adequately address it.
In Skanska USA Civil Southeast, Inc. v. Bagelheads, Inc., 75 F.4th 1290 (11th Cir. 2023), the United States Court of Appeals for the Eleventh Circuit addressed sanctions involving lost cellphone data following Hurricane Sally.
Although the company had issued litigation hold instructions, relevant cellphone information from several custodians was destroyed or became unavailable.
The district court found that Skanska intended to deprive opposing parties of the information and imposed sanctions under Rule 37(e)(2). The Eleventh Circuit affirmed, concluding that the bad-faith finding was not clearly erroneous, even though gross negligence was another plausible interpretation of the record.
The Eleventh Circuit also held that the intent-to-deprive requirement under Rule 37(e)(2) is equivalent to the bad-faith standard used in its other spoliation decisions.
The case demonstrates that issuing a litigation hold does not, by itself, establish that reasonable preservation steps were implemented. Whether a failure supports an inference of intentional deprivation depends on the particular record.
Spoliation can affect a party's ability to establish or challenge disputed facts, depending on the importance of the missing evidence and whether reliable alternatives remain available.
Missing evidence may prevent attorneys and experts from testing alternative explanations, evaluating a product defect, reconstructing an accident, or verifying disputed communications.
Disposing of a failed mechanical component, for example, may prevent metallurgical testing that could help assess fatigue, corrosion, or manufacturing-related conditions.
Such limitations may become relevant when courts evaluate prejudice and determine appropriate remedies.
When original evidence is missing, experts may need to rely on photographs, maintenance records, or other available information, potentially limiting the factual foundation for their opinions.
This does not automatically make their opinions inadmissible, but it may restrict the conclusions they can reliably support.
Spoliation disputes may require additional document production, forensic examinations, depositions, motion practice, or evidentiary hearings.
These proceedings can increase costs and complicate litigation, particularly when parties disagree about whether information was permanently lost or remains recoverable.
Qualified experts may assess how evidence was preserved, altered, or lost and what reliable information remains available. Their technical findings can inform the court, which applies the governing legal standards and determines what sanctions, if any, are warranted.
Digital forensics experts may examine deleted emails, mobile device data, electronic documents, cloud records, databases, or system logs.
Their work may involve:
Examining file metadata, timestamps, and deletion histories.
Reviewing access logs, retention policies, and backup systems.
Identifying potentially recoverable files or communications.
Comparing available forensic copies with preserved records.
Evaluating the completeness and integrity of recovered information.
Assessing whether routine system operations contributed to data loss.
The National Institute of Standards and Technology provides foundational digital forensic guidance through Guide to Integrating Forensic Techniques into Incident Response (Special Publication 800-86, 2006) and Guidelines on Mobile Device Forensics (Special Publication 800-101 Revision 1, 2014).
NIST also addresses cloud-specific forensic considerations in NIST Cloud Computing Forensic Reference Architecture (Special Publication 800-201, 2024), which describes a reference architecture for supporting forensic readiness in cloud computing environments.
These publications provide technical guidance but do not establish legal standards for spoliation sanctions.
Engineering experts may evaluate destroyed or altered products, construction materials, machinery, vehicles, or other physical evidence.
Depending on their qualifications, they may:
Review inspection photographs, reports, and available physical remains.
Examine maintenance, repair, and testing records.
Assess whether modifications affected critical evidence.
Evaluate available measurements and potential reconstruction methods.
Explain which technical questions can still be addressed reliably.
For example, an accident reconstruction expert may evaluate scene photographs, vehicle data, and witness accounts when an original vehicle is unavailable.
However, reconstruction from secondary materials may not provide the same information as direct examination of the original evidence.
Expert opinions concerning missing evidence remain subject to applicable admissibility requirements.
Under Federal Rule of Evidence 702, the proponent must show that the rule's requirements are more likely than not satisfied. The expert must be qualified, and the testimony must help the judge or jury understand the evidence or decide a disputed fact. The opinion must be based on sufficient facts or data, use reliable principles and methods, and reflect a reliable application of those methods to the facts of the case.
Federal Rule of Evidence 901 may also apply when recovered documents or electronic records require authentication.
Experts should identify the materials examined, methods used, remaining uncertainties, and limitations caused by unavailable evidence. Technical findings can inform the court's analysis without determining whether a legal preservation duty was violated.
Identify preservation duties early. Determine when litigation became reasonably anticipated and what evidence may be relevant.
Implement appropriate litigation holds. Notify relevant custodians and address routine deletion or disposal practices.
Document evidence handling. Record collection, transfers, inspections, storage conditions, and material changes.
Coordinate physical inspections. Consider appropriate notice and inspection opportunities before significant alteration, repair, or destructive testing.
Evaluate alternative evidence sources. Determine whether missing information remains available through backups, other custodians, or preserved records.
Seek court guidance when necessary. Address disputed preservation or testing procedures through appropriate motions or court orders.
Under Federal Rule of Civil Procedure 34, a party may request inspection, copying, testing, or sampling of specified documents, electronically stored information, and tangible things. These requests are subject to the applicable scope of discovery and generally concern materials within the responding party's possession, custody, or control.
Can a party be sanctioned for evidence destroyed before a lawsuit was filed?
Yes, depending on the governing law and circumstances. A duty to preserve may arise before filing when litigation is reasonably anticipated. Courts must still make the findings required for the type of evidence and remedy sought.
Does restoring deleted electronic evidence prevent spoliation sanctions?
Rule 37(e) measures are unavailable when the lost information has been restored or replaced through additional discovery. Courts may need to assess whether the recovery is sufficiently complete.
Can routine data deletion lead to spoliation sanctions?
Yes, in appropriate circumstances. Automated deletion does not necessarily excuse the loss of ESI after a preservation duty arises. Courts evaluate whether reasonable steps were taken to protect information that should have been retained.
Can expert witnesses determine whether evidence was intentionally destroyed?
Experts may identify technical indicators of deletion, alteration, or loss, but those findings do not necessarily establish intent. The court evaluates the evidence and determines whether the applicable legal standard for intentional deprivation is satisfied.
What should attorneys do when critical physical evidence is no longer available?
Attorneys should identify remaining photographs, inspection records, measurements, testing results, and relevant witnesses. Qualified experts may assess whether those materials support reliable reconstruction or technical analysis and explain which conclusions remain uncertain.
