Spoliation of evidence sanctions run from monetary penalties and cost-shifting at the low end to adverse inference jury instructions, exclusion of testimony, and outright dismissal or default judgment at the high end. Which penalty a court chooses turns on two things: how culpable the party was in losing or destroying the evidence, and how badly the loss hurt the other side’s ability to prove its case. For electronically stored information, Federal Rule of Civil Procedure 37(e) sets a two-tier framework that reserves the harshest consequences for parties who acted with intent to deprive the opponent of the evidence.
The Range of Sanctions a Court Can Impose
Judges have a graduated set of tools, and they generally start with the least severe measure that will fix the problem. The spectrum has four rough tiers.
Monetary Sanctions and Cost-Shifting
Financial penalties are the most common consequence and usually the first a court reaches for. When a party’s failure to preserve evidence forces the opponent to file motions or chase down alternative proof, the court typically orders the spoliating party to pay the opponent’s reasonable expenses, including attorney fees. Under Rule 37(a)(5), the court must impose those costs unless the failure was substantially justified or other circumstances make the award unjust.1United States Courts. Federal Rules of Civil Procedure
The real financial pain often comes from forensic recovery. When electronic data is destroyed or lost, the court may order the spoliating party to pay for specialists to image hard drives, recover deleted files, or reconstruct database records. Those investigations routinely cost tens of thousands of dollars and can exceed $100,000 in complex corporate disputes involving multiple devices and systems.
Beyond compensating the other side, a judge can also levy fines payable to the court itself as a deterrent. These penalties target the behavior rather than the opponent’s losses.
Exclusion of Evidence and Testimony
When money alone will not fix the imbalance, courts can prevent the spoliating party from using evidence or testimony tied to what was lost. If you destroy a physical product, the judge may bar your expert from testifying about its condition since the other side had no chance to inspect it. If you wipe a database, the court may prohibit you from offering any records derived from it. Rule 37(b)(2)(A) authorizes these orders.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37
In product liability cases, where the item itself is often the most important piece of evidence, losing the right to present expert analysis on that item can effectively gut a defense.
Adverse Inference Instructions
The adverse inference instruction is probably the most powerful mid-range sanction available. The judge tells the jury it may or must presume the destroyed evidence was unfavorable to the party that lost it. Under Rule 37(e)(2), a court can only give this instruction for electronic evidence after finding that the spoliating party acted with intent to deprive the other side of the information.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37
These instructions come in two forms. A permissive instruction tells jurors they are allowed to infer the missing evidence would have hurt the spoliating party, but leaves the decision to them. A mandatory instruction directs the jury to accept that presumption, though the spoliating party can still offer rebuttal evidence. The mandatory version is far more damaging because it shifts the burden: the spoliating party now has to convince the jury to disregard an assumption the judge has told them to accept.
Dismissal and Default Judgment
Terminating sanctions end the case outright. If a defendant destroys evidence with intent to deprive, the court may enter a default judgment, declaring the plaintiff the winner without a trial. If a plaintiff is the one who destroyed evidence, the court can dismiss the case with prejudice, meaning it cannot be refiled.
Rule 37(e)(2)(C) authorizes dismissal or default judgment for electronically stored information destroyed with intent to deprive. Rule 37(b)(2)(A) provides similar authority when a party disobeys a court order to produce evidence.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 Courts reserve these outcomes for situations where the destruction was deliberate and lesser sanctions cannot repair the damage.
The financial fallout from a terminating sanction goes well beyond legal fees. A default judgment can result in the full amount of damages the plaintiff sought, sometimes millions of dollars, awarded without the defendant ever getting to present a case.
How Judges Decide Which Sanction Applies
Sanctions are not picked at random. The analysis turns on two factors: the culpability of the party that lost the evidence and the prejudice suffered by the other side.
Culpability falls along a spectrum. Simple negligence, such as forgetting to suspend an auto-delete policy, sits at one end. Gross negligence, meaning you knew about the duty and did nothing meaningful to comply, sits in the middle. Intentional bad faith, like directing someone to wipe a server, sits at the far end. The more culpable the conduct, the more severe the available sanctions. Under Rule 37(e), only intentional conduct unlocks the most serious penalties, including adverse inference instructions and case-ending sanctions.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37
Prejudice measures how badly the loss actually hurt the other party’s ability to prove its case. A single lost email in a dispute with thousands of relevant documents causes minimal prejudice. The destruction of an entire category of records central to the opposing party’s claims causes severe prejudice. Under Rule 37(e)(1), the court must find prejudice before imposing even curative measures. Under Rule 37(e)(2), the finding of intent alone can support an inference of prejudice because deliberately destroying evidence implies it was harmful to the spoliator’s case.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37
Courts also weigh proportionality. Rule 26(b)(1) requires discovery obligations to be proportional to the needs of the case, considering the amount in controversy, the parties’ resources, the importance of the issues, and whether the burden of preservation outweighs its likely benefit.3Legal Information Institute. Federal Rules of Civil Procedure Rule 26 A small business in a $50,000 dispute is not expected to preserve data with the same rigor as a Fortune 500 company in a billion-dollar antitrust case. Even when intent is proven, a court is not required to impose the most severe available punishment if lesser measures would be sufficient.
The Two-Tier Framework for Electronic Evidence
Rule 37(e) is the centerpiece of sanctions law for electronically stored information. Before any sanctions come into play, the court must first find that the party failed to take reasonable steps to preserve the data and that the lost information cannot be recovered through other discovery. Perfection is not the standard. Courts evaluate preservation efforts based on what was reasonable given the party’s resources, sophistication, and the proportionality of the burden to the case.
If those threshold conditions are met, the court moves to one of two tracks. Under Rule 37(e)(1), when the opposing party has been harmed by the loss but the spoliating party did not act with intent to deprive, the court can order measures “no greater than necessary to cure the prejudice,” such as additional depositions, reopened discovery, or monetary penalties to cover the cost of recovering data through alternative means. Under Rule 37(e)(2), only when a court finds the party intentionally destroyed evidence to keep the other side from using it can it impose the harshest sanctions: a presumption that the lost information was unfavorable, an adverse inference instruction to the jury, dismissal of the case, or a default judgment.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37
A company that negligently lets an auto-delete policy wipe relevant emails faces a very different consequence than one whose IT director manually purges a server during active litigation. The intent line is where sanctions move from corrective to punitive.
Physical Evidence Is Handled Differently
Rule 37(e) only applies to electronically stored information. When physical or tangible evidence is destroyed, courts rely on their inherent authority to address the spoliation.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37 The two-tier intent framework does not automatically govern those cases, and some courts have imposed adverse inference instructions for the loss of tangible items without requiring proof of intent to deprive.
The Supreme Court has recognized that federal courts possess inherent authority to manage litigation abuses, but has cautioned that the power should be exercised with restraint and should generally defer to existing rules when those rules are adequate. In practice, courts handling physical evidence spoliation have more discretion but less predictability. In a product liability or personal injury case where a physical object is central to the dispute, the preservation stakes are particularly high because there is no duplicate copy to recover.
When the Duty to Preserve Starts
The obligation to preserve evidence does not start when you receive a lawsuit. It kicks in the moment you reasonably anticipate that litigation could happen. That could be when you receive a demand letter, learn about a regulatory investigation, witness a serious workplace accident, or hear about a potential claim from a business partner. Once that threshold is crossed, you need to stop any routine destruction of relevant documents, emails, text messages, and physical items.
Several concrete events commonly trigger the duty: receiving a complaint or legal notice, getting a preservation letter from opposing counsel, learning of a government investigation, or taking internal steps like hiring an attorney or preparing an incident report. The duty extends to electronically stored information, which courts treat with particular scrutiny because digital data is easy to delete and hard to recover once gone.2Legal Information Institute. Federal Rules of Civil Procedure Rule 37
If you wait until a complaint lands on your desk to think about preservation, you are already late. The clock that courts measure against started earlier.
Criminal Exposure for Destroying Evidence
Spoliation is not only a civil problem. Destroying evidence can be a federal crime carrying serious prison time, especially when a government investigation is involved.
Under 18 U.S.C. § 1519, anyone who knowingly destroys, alters, or falsifies records with the intent to obstruct a federal investigation or bankruptcy proceeding faces up to 20 years in prison, a fine, or both.4Office of the Law Revision Counsel. 18 USC 1519 – Destruction, Alteration, or Falsification of Records in Federal Investigations and Bankruptcy The statute is broad. It covers any record, document, or tangible object and does not require a pending proceeding; contemplation of a federal matter is enough.
A separate statute, 18 U.S.C. § 1512(c), targets anyone who corruptly destroys or conceals a record or object with the intent to impair its use in an official proceeding. The penalty is the same: up to 20 years imprisonment.5Office of the Law Revision Counsel. 18 USC 1512 – Tampering With a Witness, Victim, or an Informant Section 1512(b) extends the same penalty to anyone who persuades or intimidates another person into destroying evidence or withholding it from a proceeding.
Criminal prosecution for evidence destruction is not common in ordinary civil litigation, but it becomes a real risk when the underlying dispute involves regulatory investigations, securities fraud, healthcare fraud, or any matter touching a federal agency.
Consequences for Attorneys
Lawyers face their own layer of liability. ABA Model Rule 3.4(a) prohibits an attorney from unlawfully destroying or concealing material with potential evidentiary value, and bars lawyers from advising or helping anyone else do so.6American Bar Association. Model Rules of Professional Conduct Rule 3.4 – Fairness to Opposing Party and Counsel Every state has adopted some version of this rule, and violations can result in suspension or disbarment.
An attorney who tells a client to delete emails, shred documents, or “clean up” files after learning that litigation is foreseeable is not just risking sanctions in the case. They are risking their license. Counsel is also expected to implement and monitor a litigation hold once the duty to preserve attaches, which means issuing written hold notices, identifying the specific types of data to be preserved, suspending automatic deletion policies, and following up to confirm compliance.
Separate Lawsuits for Spoliation
Beyond sanctions within an existing lawsuit, a minority of states allow a separate lawsuit against the party that destroyed evidence. About 14 states have recognized some form of an independent spoliation tort, while the majority of states that have considered the question have declined to create one. Where recognized, these claims can target both parties to the original litigation and third parties who destroyed evidence. The elements and availability vary significantly by jurisdiction. In states that do not recognize the independent tort, the only recourse for spoliation is through sanctions in the underlying case.
