Common Discovery Objections: Privilege, Burden, and Sanctions

Common discovery objections in federal civil litigation fall into a handful of recognized categories: relevance and proportionality, privilege and work product, vagueness or overbreadth, undue burden, inaccessibility of electronically stored information, and improper form. Each has its own standard, and each has to be stated with specificity and raised on time. A boilerplate objection — the kind that lists five grounds in a single line without explaining any of them — is treated by courts the same as no objection at all, which means the right to withhold is gone and sanctions may follow.

Relevance and Proportionality

Every discovery request has to clear two hurdles under Rule 26(b)(1): the information sought must be relevant to a claim or defense, and the request must be proportional to the needs of the case.¹ Discovery relevance is broader than trial relevance. Information doesn’t need to be admissible to be discoverable, as long as it relates to the parties’ claims or defenses.

Proportionality weighs six factors: the importance of the issues at stake, the amount in controversy, the parties’ relative access to the information, each party’s resources, how important the discovery is to resolving the dispute, and whether the burden or expense outweighs the likely benefit.¹ The objecting party carries the burden of showing with specificity why a request fails one of these tests. Writing “this request is not proportional to the needs of the case” accomplishes nothing.

An effective proportionality objection identifies a concrete problem. Retrieving five years of data from a decommissioned system would cost $200,000, the case involves $50,000 in damages, and the same information is available from a more accessible source. That level of detail gives the requesting party something to work with and gives the court a reason to intervene. Vague assertions about burden are where most of these objections fall apart.

Privilege and Work Product

Some information is shielded regardless of how relevant it is. The two most common protections are attorney-client privilege and the work product doctrine, and confusing them is a common mistake with real consequences.

Attorney-Client Privilege

Attorney-client privilege protects confidential communications between a client and their lawyer when the purpose is seeking or providing legal advice. The protection covers in-person conversations, emails, and text messages, as long as the communication was intended to be confidential and made in the context of a legal relationship. The privilege belongs to the client, not the lawyer, and it can be waived — intentionally or accidentally — if the communication is shared with third parties outside that relationship.

Work Product

The work product doctrine is broader. It protects documents and materials prepared by an attorney, or by someone working at the attorney’s direction, in anticipation of litigation.¹ This covers research memos, litigation strategy notes, and witness interview summaries. Unlike attorney-client privilege, work product protection extends to materials created by non-attorneys, so a consultant’s report prepared for litigation qualifies. The protection is strongest for materials reflecting the attorney’s mental impressions and legal theories, which are virtually immune from discovery. Factual work product can sometimes be obtained if the requesting party shows a substantial need and cannot get the equivalent information another way.

Privilege Logs

Claiming privilege isn’t as simple as stamping “privileged” on a response. Rule 26(b)(5)(A) requires the withholding party to expressly claim the protection and describe the withheld materials in enough detail that the opposing side can evaluate the claim without revealing the privileged content itself.¹ In practice this means a privilege log listing the author, recipient, date, general subject matter, and the specific legal basis for each withheld item. A sloppy or incomplete log can result in the court finding the privilege waived.

Clawback Orders

Because large document productions inevitably involve mistakes, parties often seek a court order under Federal Rule of Evidence 502(d) providing that inadvertent disclosure of privileged material does not waive the privilege. These clawback orders let a party retrieve a mistakenly produced document without losing the underlying protection, and the order’s effect extends to other federal and state proceedings.² Private clawback agreements between parties are less powerful, binding only the signatories unless incorporated into a court order.

Protective Orders for Sensitive Business Information

Trade secrets, proprietary formulas, and confidential commercial data can also be shielded from unrestricted disclosure. Under Rule 26(c), a court may issue a protective order for good cause, restricting who can see the material and how it can be used.¹ The available protections range from attorneys’ eyes only designations, to sealed depositions, to prohibitions on inquiry into certain topics. A protective order doesn’t block production; it allows production under controlled conditions, which is often a more realistic outcome than outright refusal.

Vagueness, Overbreadth, and Undue Burden

Some objections target the request itself rather than the information it seeks. A request that is vague, ambiguous, or overbroad lacks the precision needed for a meaningful response. An overbroad request typically fails to limit the scope by time period, subject matter, or the people whose files must be searched. Asking for “all documents related to the company’s finances” with no date range is the classic example.

These objections require more than the label. The responding party has to explain what makes the request unclear and, where possible, suggest how it could be narrowed to reach discoverable material. Under Rule 34(b)(2)(C), an objection to a document request must also state whether any responsive materials are being withheld on the basis of that objection.³ This prevents a party from lodging an objection and then silently withholding documents behind it.

The “unduly burdensome” objection comes up when compliance would require disproportionate time, expense, or disruption — reviewing a decade of records across dozens of custodians, for example. Even when this objection sticks, the responding party still has to produce whatever portion of the request is not objectionable. That reality encourages compromise: narrowing the date range, reducing the number of custodians, or agreeing to keyword-based searches rather than manual review.

Cost-Shifting

When production costs are genuinely excessive, the court can shift some or all of those costs to the requesting party. Courts weigh how narrowly tailored the request is, whether the same information is available from cheaper sources, the total cost relative to the amount in controversy, each party’s resources, and the importance of the issues at stake. Cost-shifting comes up most often with electronically stored information, where restoring archived data or processing large volumes of files can generate significant expense.

Electronically Stored Information

Electronic data creates its own category of objections because the volume, format, and storage methods differ fundamentally from paper documents. Rule 26(b)(2)(B) carves out a specific protection: a party doesn’t have to produce electronically stored information from sources it identifies as not reasonably accessible because of undue burden or cost.¹ Backup tapes, legacy systems, and damaged storage media are common examples. The responding party bears the burden of proving inaccessibility, and even then the court can order production if the requesting party shows good cause.

Format is another frequent battleground. A party that objects to producing electronic files in the format the requesting party wants must state the objection with specificity and identify the alternative format it intends to use.³ This matters because metadata embedded in electronic files can reveal editing history, authorship, and timestamps that a flat PDF would strip away. Metadata can also contain privileged or irrelevant information, giving the producing party a legitimate reason to object to a native-format production. Format objections not raised within 30 days of service risk being waived.

Objections During Depositions

Deposition objections operate under different rules than written discovery, and misunderstanding the difference gets attorneys in trouble constantly. During a deposition, objections must be stated concisely, in a nonargumentative and nonsuggestive manner, and the deponent still answers the question.⁴ The objection is preserved on the record for the court to rule on later. There is no judge present to sustain or overrule anything in real time.

An attorney may instruct a deponent not to answer only in three narrow situations: to preserve a privilege, to enforce a limitation the court has already ordered, or to suspend the deposition and file a motion to terminate it because the examination is being conducted in bad faith or in a way that unreasonably annoys or embarrasses the deponent.⁴ Outside those three situations, instructing a witness not to answer is improper and can result in sanctions. Speaking objections — lengthy, coaching objections that signal the “right” answer to the deponent — carry the same risk.

Requests for Admissions

Requests for admissions under Rule 36 carry a consequence no other discovery tool matches: if you don’t respond within 30 days, the matter is automatically deemed admitted.⁵ No warning, no grace period. A deemed admission is treated as conclusively established for the case unless the court later grants a motion to withdraw it, which requires showing that withdrawal would help resolve the case on its merits and would not unfairly prejudice the requesting party. Litigants who miss this deadline sometimes find core facts of the case locked against them.

When you do respond, a denial must fairly address the substance of the request. If you cannot truthfully admit or deny, you must explain in detail why, and you can only claim insufficient knowledge if you have made a reasonable inquiry and still lack enough information. Objections must state their grounds, and a party cannot object solely because the request presents a genuine issue for trial.⁵ The requesting party can challenge a weak answer or objection by motion, and the court can order the matter deemed admitted if the response doesn’t comply.

Third-Party Subpoenas

Discovery doesn’t only target the parties to the lawsuit. Under Rule 45, a party can subpoena documents, electronic records, or testimony from non-parties. A non-party who receives a subpoena to produce documents may serve a written objection before the earlier of the compliance deadline or 14 days after the subpoena is served.⁶ Once a timely objection is served, the requesting party must obtain a court order before the non-party is required to produce anything.

Non-parties get somewhat more protection than the actual litigants. Courts recognize that third parties have no stake in the outcome and shouldn’t bear significant costs to advance someone else’s case. When a subpoena imposes an undue burden, the court can quash it entirely or shift the production costs to the party that issued it. The same proportionality and relevance standards apply, but courts tend to apply them more protectively when the burden falls on someone who did not choose to be involved.

Deadlines, Specificity, and Waiver

The procedural rules are unforgiving. Miss a deadline or state an objection too vaguely, and you lose the right to assert it.

Response Deadlines

The default deadline for responding to interrogatories, requests for production, and requests for admissions is 30 days from the date of service.⁷³ The parties can agree to a different timeline, or the court can set one. State courts often have their own deadlines, ranging from roughly 20 to 45 days depending on the jurisdiction and the method of service. Any objection not raised within the applicable deadline is waived, though courts have limited discretion to excuse a late objection for good cause.

Specificity

Every objection must state its grounds with specificity. For interrogatories, Rule 33(b)(4) makes this explicit and treats any unstated ground as waived.⁷ Rule 34 imposes the same requirement for document requests, with the added obligation to state whether responsive materials are being withheld.³ Writing “objection: overbroad, vague, and unduly burdensome” on every response is functionally the same as not objecting at all. The objection should identify the specific deficiency and, where relevant, what the responding party is willing to provide.

Interrogatory Limits

Rule 33 caps interrogatories at 25 per party, including discrete subparts, unless the court grants leave for more or the parties agree otherwise.⁷ This cap often drives objections about whether a compound question counts as one interrogatory or several. A question asking a party to identify every communication, its date, participants, and subject matter is realistically four subparts, not one.

Meet and Confer

Before filing a motion to compel, the moving party must certify that it attempted in good faith to resolve the dispute without court involvement.⁸ Some courts require an actual conversation; a letter or email exchange alone doesn’t satisfy the obligation. Filing without this certification is grounds for denial, and the process itself resolves a surprising number of disputes when both sides approach it honestly.

Sanctions for Improper Objections

Discovery objections carry financial risk for both sides. When a court grants a motion to compel, Rule 37(a)(5) requires the losing party, or the attorney who advised the meritless objection, to pay the other side’s reasonable expenses, including attorney’s fees, unless the objection was substantially justified or special circumstances make the award unjust.⁸ The same rule works in reverse: if the motion is denied, the party that filed it can be ordered to pay the other side’s costs in opposing it.

The stakes escalate when a party disobeys a court order compelling discovery. At that point the court’s toolbox expands to include:

Adverse inference, treating disputed facts as established in the requesting party’s favor.
Evidentiary bars prohibiting the disobedient party from supporting or opposing certain claims or introducing certain evidence.
Striking parts or all of the offending party’s complaint or answer.
Default judgment or dismissal, ending the case against the non-complying party.
Contempt of court.

Courts can also inform the jury about a party’s failure to comply, which is the kind of instruction no litigant wants a jury to hear.
