Discovery abuse covers a range of tactics a party or lawyer uses to twist the pretrial evidence-exchange process — hiding what they should turn over, giving answers that don’t answer, drowning the other side in demands, or steering witnesses through a deposition. Common examples of discovery abuse include destroying documents, offering evasive or boilerplate responses, serving excessive requests designed to run up costs, and coaching witnesses through improper deposition objections. Courts have broad power to punish this conduct, from ordering the offender to pay the other side’s fees all the way to dismissing the case.
Destroying or Hiding Evidence
The most serious form of discovery abuse is spoliation: destroying, altering, or concealing evidence the other side needs. The duty to preserve relevant materials starts as soon as litigation is filed or reasonably anticipated, and it binds both sides.1Bloomberg Law. Litigation, Overview – Duty to Preserve: Discovery Federal courts describe spoliation as the destruction or significant alteration of evidence, or the failure to preserve it, for use in pending or foreseeable litigation.2United States Courts. Preservation and Spoliation Revisitedp>
What it looks like in practice: a company sued over a defective product deletes internal emails discussing known flaws. An employer facing a discrimination claim alters personnel files. A party to a business dispute shreds financial records. Once evidence is gone, the other side can never fully recover it, and the destruction itself suggests the material was damaging.
When litigation becomes reasonably foreseeable, a party is expected to pause routine document-destruction policies and issue a “litigation hold” so relevant materials are preserved.3U.S. District Court for the District of Nebraska. Litigation Holds: Ten Tips in Ten Minutes The trigger doesn’t have to be a filed complaint. A demand letter, a regulatory inquiry, or a contentious termination can be enough. Courts ask whether the party knew or should have known a lawsuit was on the horizon.1Bloomberg Law. Litigation, Overview – Duty to Preserve: Discovery
Lost Electronic Evidence
Most spoliation disputes today involve electronically stored information: emails, texts, database records, cloud files. Federal Rule of Civil Procedure 37(e) sets up a two-tier framework when electronic evidence is lost because a party failed to take reasonable steps to preserve it and it can’t be restored through other discovery.4Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
If the loss was negligent and caused the other side prejudice, the court can order measures “no greater than necessary” to cure the harm, such as additional depositions or expert reconstruction. If the party acted with intent to deprive the other side of the evidence, the court can presume the lost information was unfavorable, instruct the jury to draw that conclusion, or dismiss the case outright. That is where an auto-delete policy left running after a preservation duty has kicked in becomes dangerous. To a judge reviewing the timeline, it can look a lot like intentional destruction.
False, Evasive, or Boilerplate Responses
A party doesn’t need to destroy anything to abuse discovery. Giving false, misleading, or deliberately incomplete answers is equally improper and arguably more common. A witness lying under oath at deposition is the obvious version. The quieter versions are harder to catch and just as harmful.
One frequent maneuver is the document-dump non-answer: asked to identify people with knowledge of a key event, a party points to thousands of pages of unorganized files instead of naming anyone. Another is hiding behind boilerplate objections — stamping every request with “vague and ambiguous” or “overly broad” and providing no substantive response. Both force the other side to spend time and money filing motions to get a straight answer, which is often the whole point.
In federal court, the attorney who signs discovery responses is personally on the hook. Under Rule 26(g), the signature certifies that the response is consistent with the rules, is not filed for an improper purpose like harassment or delay, and is proportional to the case.5Bloomberg Law. Litigation Overview – Rule 26(g) Reasonable Inquiry Certification: Discovery That signature represents that the lawyer conducted a reasonable inquiry before signing. When a court finds the certification was baseless, the attorney can be sanctioned personally.
Excessive or Harassing Requests
Abuse doesn’t only come from the side withholding information. The requesting side can weaponize discovery too, by burying the opponent in so many demands that compliance becomes unbearable and settlement starts to look cheaper than the fight.
Federal rules push back. A party is limited to 25 written interrogatories, including subparts, unless the court orders otherwise.6Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties Creative attorneys can still push. In a simple contract dispute, a party might demand twenty years of financial records, personnel files for employees with no role in the transaction, and communications with every vendor the company has ever used.
The test is proportionality. Discovery must be proportional to the needs of the case, taking into account what’s at stake, the amount in controversy, each party’s relative access to the information, and whether the burden of producing it outweighs the likely benefit. A party facing disproportionate demands can seek a protective order to narrow them. Many discovery fights end there, with a judge drawing the line between legitimate fact-finding and tactical harassment.
Improper Deposition Conduct
Depositions are a frequent stage for attorney misconduct. The rules require objections to be stated concisely, without argument, and without suggesting an answer to the witness.7Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination Some attorneys treat that requirement as a suggestion.
The classic abuse is the speaking objection. Instead of “Objection, form,” the attorney launches into a paragraph: “Objection, the question is misleading, assumes facts not in evidence, and the witness has already explained that she wasn’t present for that meeting.” That isn’t really an objection. It’s coaching — telling the witness what to say, or more often what not to say.
Another common violation is instructing a witness not to answer. The rules allow that in only three situations: to protect a legal privilege, to enforce a court-imposed limitation on the deposition, or to allow the attorney to seek a court order terminating the examination.7Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination Silencing a witness because a question seems irrelevant or unfavorable is not on that list. When it happens anyway, the other side often has to suspend the deposition, take the fight to the judge, and come back later. That delay is exactly what makes the tactic effective.
Courts can sanction anyone who “impedes, delays, or frustrates the fair examination of the deponent,” including the reasonable expenses and fees the other side incurred.7Legal Information Institute. Federal Rules of Civil Procedure Rule 30 – Depositions by Oral Examination
What to Do If You’re on the Receiving End
You typically can’t skip straight to a sanctions motion. Federal Rule 37 requires any motion to compel discovery to include a certification that the moving party tried in good faith to resolve the dispute without court involvement.4Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Many state courts have the same requirement. Skipping it can get your motion denied, and the court won’t award you expenses if you filed without trying to work things out.
In practice, that means sending a detailed letter or email to opposing counsel spelling out what’s deficient about their responses and giving a reasonable deadline to cure. Keep a record of every communication. If the other side ignores you or refuses to comply, that correspondence is your evidence when you file the motion. A perfunctory phone call the morning of filing won’t cut it.
If the motion is granted and the other side still refuses to comply with the court’s order, the stakes change. At that point you’re no longer in a discovery dispute. You’re dealing with defiance of a court order, which opens the door to the full range of sanctions.
Sanctions Courts Can Impose
Rule 37 gives federal courts a graduated toolkit, and most state courts have parallel provisions.4Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Severity tracks how willful the conduct was and how much harm it caused.
- Monetary sanctions. The most common penalty. The court orders the abusive party or their attorney to pay the reasonable expenses, including fees, that the misconduct caused.
- Evidentiary sanctions. The court bars the offender from using certain evidence or from supporting or opposing specific claims and defenses.
- Established facts. The court orders that certain facts be treated as proven for the case, matching the harmed party’s version.
- Adverse inference instructions. In spoliation cases, the court tells the jury it may or must presume the destroyed evidence was unfavorable to the party that destroyed it.8Judicature. Rule 37(e) – The New Law of Electronic Spoliation
- Striking pleadings, dismissal, or default judgment. The nuclear options. Courts reserve these for the worst misconduct: repeated defiance of court orders, intentional destruction of critical evidence, or a pattern of bad faith that makes a fair trial impossible.
There is also an automatic consequence for failing to disclose information required under the rules: the party generally cannot use the undisclosed witness or evidence at trial, at a hearing, or on a motion.4Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions A key expert you never disclosed, or a document you hid, may be permanently off-limits. Discovery obligations are not optional, and courts have both the tools and the willingness to enforce them.
