Discovery Proportionality Requirements Under Rule 26

Under Federal Rule of Civil Procedure 26(b)(1), the discovery proportionality requirements under Rule 26 mean that a request must be both relevant to a claim or defense and proportional to the needs of the case, measured against six factors the court weighs together. Relevance alone is no longer enough. Since the 2015 amendments moved proportionality into the core definition of what is discoverable, every request, response, and objection has to be built with those six factors in mind.¹

The Six Factors a Court Weighs

The factors are not a checklist where any single item controls. Courts weigh them collectively and tailor the analysis to the case in front of them.

Importance of the issues at stake: Cases involving constitutional rights, public safety, or widespread harm carry more weight than a routine contract dispute. Broad discovery is easier to justify when the outcome affects people beyond the two parties.
Amount in controversy: A $50,000 production cost looks very different in a $10 million antitrust case than in a $75,000 breach-of-contract dispute. Courts compare projected cost against the realistic value of the claims.
Relative access to relevant information: When one side holds nearly all the documents, courts account for that imbalance. A defendant sitting on internal records cannot easily call the search too burdensome when the plaintiff has no alternative way to get them.
The parties’ resources: A multinational corporation and a solo plaintiff do not have the same capacity to absorb discovery costs. This factor prevents wealthier litigants from burying opponents under production demands.
Importance of the discovery in resolving the issues: Requests aimed at information that could actually change the outcome get more deference than requests aimed at peripheral or cumulative material.
Whether the burden or expense outweighs the likely benefit: The catch-all balancing factor. Even relevant information can be denied or narrowed when the cost and disruption exceed what the requesting party stands to gain.

A high-stakes case with a large amount in controversy can justify expensive discovery that would be flatly disproportionate in a smaller dispute. There is no fixed formula.¹

Who Has to Prove What

The 2015 Advisory Committee Notes are explicit: moving proportionality into the scope definition does not saddle the requesting party with the burden of addressing every proportionality consideration up front. It also does not let the responding party refuse discovery with a boilerplate objection that the request “is not proportional.” Both sides share responsibility.¹

In practice, the split works like this. The requesting party must show the information is relevant to a claim or defense. Once relevance is established, the objector has to give specific, concrete reasons why the request is disproportionate. “Overly broad” and “unduly burdensome” without supporting detail get rejected. That is why burden affidavits and cost estimates carry so much of the weight in real proportionality fights.

What a Real Proportionality Objection Contains

An objection without evidence to back it up is worse than useless. It signals to the court that the objector has not done the work. Effective challenges are built on documentation prepared before anything is filed.

Burden Affidavits and Cost Estimates

A burden affidavit is a signed declaration laying out the specific hardship of compliance. It identifies the data systems that would need to be searched, the estimated volume of data in those systems, the number of custodians involved, the hourly rates of the technical staff who would collect and review the material, and the projected total cost. Granular detail moves the needle; general assertions do not.

Legal teams also map key custodians, meaning the specific employees or individuals whose emails and files are most likely to hold relevant material. Matching custodians to data sources gives the court a factual basis for narrowing requests instead of arguing in the abstract. Forensic collection adds cost on top of review. Professional forensic services commonly charge $250 to $350 per hour, with per-device fees often running higher for computers and mobile devices.

Privilege Logs

Any document withheld on privilege grounds has to be logged. A privilege log identifies each withheld document by date, author, recipients, general subject matter, present location, and the specific privilege claimed. The point is to give the requesting party enough information to evaluate the claim without exposing the protected content.²

In large productions, privilege logging is one of the most expensive parts of discovery. Contract attorneys performing document review typically charge $25 to $45 per hour, and the sheer volume of documents means the total often dwarfs other discovery costs. That expense is one of the concrete numbers a burden affidavit can put in front of the judge.

Response Deadlines and the Boilerplate Trap

A party served with a document request under Rule 34 has 30 days to respond in writing. If the request was delivered before the Rule 26(f) conference, the clock runs 30 days from that conference instead.³

The response has to address each request individually. For each item, the party either agrees to produce or states specific grounds for objecting, and each objection must state whether any responsive materials are being withheld on that basis. Boilerplate objections copied across every response are exactly what courts penalize. Missing the deadline or failing to state objections with specificity risks waiving those objections entirely.³

How Proportionality Disputes Get Resolved

Meet and Confer

Before filing any discovery motion, the parties must engage in a good-faith meet-and-confer discussion. It is not optional. Motions to compel and motions for protective orders both require a certification that the moving party tried to work things out first, and a motion without that certification can be denied on that basis alone.⁴

The conversation works best when both sides come with specifics. The requesting party explains why the information matters to its claims. The responding party presents cost estimates and burden analysis. Compromises reached here — narrowing date ranges, reducing custodians, agreeing to phased searches — save both sides the expense and unpredictability of a contested motion.

Motions to Compel and Protective Orders

When the meet and confer fails, the requesting party can file a motion to compel under Rule 37(a), including the certification of good-faith conferral.⁵ The responding party can instead file for a protective order under Rule 26(c), asking the court to limit, restructure, or prohibit the discovery. Protective orders take many forms: forbidding certain inquiries, prescribing a different method, restricting who may view produced materials, or allocating expenses to the requesting party.¹

The judge sets a hearing where both sides present their evidence, the burden affidavits, and their arguments on the six factors. The court then narrows scope, imposes conditions, shifts costs, or orders full production.

Cost-Shifting for Production

Separate from any expenses tied to the motion itself, Rule 26(c)(1)(B) lets a protective order specify how production expenses are allocated, including requiring the requesting party to bear part or all of the cost. This comes up most often with electronically stored information that is not reasonably accessible due to undue burden or cost, such as backup tapes, legacy systems, or decommissioned databases. A court may order discovery from those sources if the requesting party shows good cause, but it can condition the order on the requesting party paying for retrieval. The 2015 Advisory Committee Notes caution that production cost-shifting should not become routine; the default remains that a responding party pays its own production costs.¹

Fee-Shifting on the Motion Itself

This is where proportionality fights get expensive in ways parties do not anticipate. Under Rule 37(a)(5), if a motion to compel is granted, or if the requested discovery is turned over after the motion is filed, the court must order the losing side to pay the winner’s reasonable expenses of bringing the motion, including attorney fees. The payment is mandatory unless the objection was substantially justified or special circumstances make the award unjust.⁵

The same rule cuts the other way. If the motion is denied, the court must require the movant to pay the opposing party’s expenses in fighting it, again unless the motion was substantially justified. When a motion is granted in part and denied in part, the court can apportion expenses between the sides.⁵ This fee-shifting mechanism is the main reason experienced attorneys take meet-and-confer seriously. Losing a discovery motion means paying for both sides’ lawyers.

Rule 26(g): Personal Exposure for the Signing Attorney

Every discovery request, response, and objection must be signed by the attorney of record. That signature is not a formality. Under Rule 26(g), signing certifies that the paper is consistent with the rules, is not interposed for an improper purpose such as delay or harassment, and is neither unreasonable nor unduly burdensome given the needs of the case.¹

If the court determines that a certification violated this standard without substantial justification, it must impose an appropriate sanction on the signer, the party, or both. The sanction is mandatory. Its form is left to the judge. Attorneys who send out shotgun requests or reflexively object to everything are personally at risk, which is precisely what the rule was designed to force them to think about before they sign.

What Sits Alongside Proportionality

Preservation and Spoliation

The duty to preserve evidence starts before any discovery request is served. Once a party reasonably anticipates litigation, it must suspend routine document destruction and issue a litigation hold. Triggering events include receiving a demand letter, learning of a government investigation, or internal discussions about potential claims.⁶

When electronically stored information is lost because a party failed to preserve it, Rule 37(e) sets two tiers. If the loss prejudices another party and no lesser measure can cure the harm, the court may order measures no greater than necessary to address the prejudice, such as allowing additional discovery or instructing the jury about the loss. The severe sanctions — presuming the lost information was unfavorable, giving an adverse-inference instruction, dismissing the case, or entering default — are reserved for a finding that the party acted with the intent to deprive the other side of the evidence. That harsher tier does not require a separate showing of prejudice.⁵

Disobeying a Discovery Order

Ignoring a court’s discovery order is one of the fastest ways to lose a case without a trial. Rule 37(b)(2) authorizes escalating sanctions when a party fails to obey: treating disputed facts as established against the disobedient party, prohibiting them from introducing designated evidence, striking pleadings, dismissing the action, entering default judgment, or holding the party in contempt. On top of any of those, the court must require the noncompliant party or its attorney to pay the reasonable expenses, including attorney fees, caused by the failure to comply, unless the failure was substantially justified or an expense award would be unjust.⁵
