Proportionality in ESI Discovery: Scoping Requests Sensibly

Proportionality is one of the most invoked and least specific words in discovery disputes. Since the 2015 amendments it sits inside the definition of scope in Federal Rule of Civil Procedure 26(b)(1), which means every ESI request and every objection is supposed to be measured against the needs of the case, not relevance alone. Saying the word, though, does very little; the side with facts about the data usually carries the argument.

This guide translates the six factors into questions your team can answer, lists the levers that make an ESI request proportionate, shows how to object without boilerplate, and explains how to build a burden record as the case moves. It works from both sides of the table, because many firms draft and respond in the same month.

What does proportionality mean under Rule 26(b)(1)?

Discovery must concern nonprivileged matter relevant to a claim or defense and proportional to the needs of the case. The rule lists six considerations:

1. The importance of the issues at stake in the action
2. The amount in controversy
3. The parties’ relative access to relevant information
4. The parties’ resources
5. The importance of the discovery in resolving the issues
6. Whether the burden or expense of the proposed discovery outweighs its likely benefit

Information within that scope need not be admissible to be discoverable. The 2015 advisory committee note adds two points worth knowing: the change does not place on the requesting party the burden of addressing every factor, and it does not authorize boilerplate objections that discovery is not proportional.

Two companion provisions matter. Rule 26(b)(2)(C) requires the court to limit discovery that is unreasonably cumulative or duplicative, obtainable from a more convenient source, or outside Rule 26(b)(1). And under Rule 26(g)(1)(B)(iii), signing a discovery request certifies that it is not unreasonable or unduly burdensome given the needs of the case. Many states have adopted similar language; some still use older formulations of scope, so confirm which standard governs your matter.

The six factors, translated into questions your team can answer

Each factor becomes useful once it is tied to a fact you can prove. This is the working version for case teams:

How do you make an ESI request proportionate?

Narrow along the dimensions that cut volume without cutting relevance. The common levers:

• Custodians: the people who actually communicated about the issue, starting with the key few
• Dates: ranges tied to the events in the pleadings
• Sources: the phone and primary email account before archives and backups
• Participants: message threads between named people rather than whole devices
• Search terms: tested against real data, with hit counts shared before anyone commits
• Phasing: first-tier sources now, with a checkpoint before the next tier
• Sampling: review a sample to estimate value before ordering a full review
• “Documents sufficient to show”: for background facts that need proof, not every record
• Stipulations and admissions: in place of document discovery for undisputed facts

The narrowed version is easier to defend, faster to answer and more likely to produce something usable. Our guide to requests for production of text messages applies the same approach to message discovery.

How do you object on proportionality grounds without boilerplate?

Tie the objection to specific facts about the data and the case, say what you will produce instead, and state whether anything is withheld. Rule 34(b)(2)(B) requires grounds stated with specificity, and Rule 34(b)(2)(C) requires saying whether responsive materials are being withheld on the basis of the objection.

For sources that are not reasonably accessible because of undue burden or cost, such as deleted data recoverable only by forensic tools, Rule 26(b)(2)(B) lets the responding party identify the sources rather than search them. On a motion, that party must show the inaccessibility, and the court may still order discovery for good cause with conditions. Rule 26(c)(1)(B) also allows protective orders that allocate expenses.

Answering a proportionality objection from the requesting side

When your request draws a proportionality objection, the most effective reply is usually as specific as the objection should have been. Identify the allegation the source bears on and explain why this source is the best or only place the information lives. Point out any imbalance in access, for example when the other side holds the only copy of the records. Then offer something concrete: a shorter date range, named participants, tested terms, a phased first look or a sample. Putting a reasonable narrowing proposal in writing frames the dispute well if it reaches the court.

How does proportionality play out in family and small-dollar matters?

A low amount in controversy does not automatically make discovery disproportionate. Nonmonetary stakes and unequal access to information can weigh heavily.

• Custody matters: the child’s welfare makes the issues important, but discovery into a parent’s entire digital life is rarely proportionate. Narrow requests to conduct bearing on parenting, and protect children’s information. Family courts often apply their own discovery limits; see our discovery in divorce cases workflow.
• Housing and consumer matters: the dollar amount may be small while one side holds all of the records, such as maintenance logs or account histories. Relative access matters here.
• Resource gaps: an individual facing an organization may have limited ability to absorb costs, and the rule invites courts to consider that.
• Safety concerns: real abuse occurs, and discovery should not become a tool for harassment in either direction. Protective orders can limit the use and dissemination of sensitive information.

How do you build a proportionality record as you go?

Gather the facts while the work happens, not when the motion is due.

1. Map volumes. Record item counts and date spans for every source when it is collected.
2. Run hit reports. For proposed terms, record total and unique hits by term and by source.
3. Time a sample. Review a sample and track the actual time, so estimates come from this matter.
4. Price it in writing. Get any vendor quotes or internal cost estimates documented.
5. Confirm proposals in letters. Summarize each offer and counteroffer after the ESI meet-and-confer.
6. Keep declaration-ready notes. Note who did each measurement and how, so the record can be sworn to later.

Full-text search across ingested items, as in Evidence Helper, makes it practical to test proposed terms against what your client actually holds before you negotiate them.

What mistakes undercut a proportionality position?

• Identical objections pasted under every request
• Objecting, then producing without saying what was withheld
• Burden claims with no volumes, hit counts or time estimates
• Refusing to propose any alternative scope
• Requesting “all ESI” and narrowing only after a motion
• Ignoring that the other side has no other way to get the information

How hard to press a proportionality argument is a strategic decision for the attorney on the matter, and courts weigh these factors case by case, so teams working in an unfamiliar court should confirm local practice with counsel licensed in that jurisdiction.
