Decision framework
When a discovery dispute is worth handing to a neutral.
Knowing when to use a discovery neutral comes down to six fights that account for most of the time and money lost in modern discovery. For each, here is what the fight looks like, why motion practice is slow, what a neutral does instead, and the procedural vehicle that gets you there.
The six disputes
Six recurring fights account for most of the cost.
When a case turns on how the technology actually works, the motion calendar is the slow path. These are the disputes worth handing to a technically fluent neutral.
ESI protocol fights
Format, scope, custodians, and metadata disputes that keep production from starting.
Spoliation of evidence
Servers, mobile devices, and cloud accounts said to be lost, wiped, or altered.
TAR & search-term protocols
Disagreements over predictive coding, validation, and search-term lists.
Privilege review disputes
Log volume, methodology, and clawback fights across hundreds of thousands of documents.
Forensic inspection protocols
Protocols governing access to and imaging of an opposing party's systems.
Cross-border discovery
U.S. discovery obligations against GDPR and Hague-Convention limits on moving data.
The fights in detail
What each fight looks like — and what a neutral does.
For every dispute: the fight, why motion practice is slow, what a neutral does instead, and the procedural vehicle that gets you there.
01 — ESI protocol fights
Format, scope, custodians, date ranges, deduplication, and metadata fields — the parties cannot agree on the rules of production, so production never starts.
- The fight
- Each side proposes an ESI protocol; the disagreements are technical, the stakes are framed as precedent, and neither side will move first.
- Why motion practice is slow
- The court schedules briefing on a question that is really an engineering negotiation. Months pass before a judge with a full docket reaches a protocol the parties could have settled in a session.
- What a neutral does
- Convenes the parties, pressure-tests each proposal against how the systems actually work, and produces a workable protocol — by agreement where possible, by recommendation or order where not.

02 — Spoliation of evidence
Servers, mobile devices, cloud accounts, collaboration tools, and even biometric timekeeping data are said to be lost, wiped, or altered — and one side wants sanctions.
- The fight
- An allegation that ESI was not preserved, escalating toward a sanctions or adverse-inference motion that can swing the case.
- Why motion practice is slow
- Resolving it requires reconstructing what happened on the systems — retention settings, sync behavior, deletion logs — which courts rarely have time or technical footing to do on a paper record.
- What a neutral does
- Examines the forensic facts, separates genuine loss from ordinary system behavior, and frames a proportionate record for the court — often defusing the sanctions fight before it consumes the case.

03 — TAR and search-term protocols
Disputes over predictive coding, training, validation, recall and precision targets, and search-term lists — methodology fights dressed up as discovery motions.
- The fight
- One side challenges the other's use of technology-assisted review or proposed search terms as inadequate, opaque, or overbroad.
- Why motion practice is slow
- The dispute turns on statistics and information-retrieval methods that resist resolution by competing declarations and a hearing.
- What a neutral does
- Sets a defensible validation protocol, mediates the recall and sampling questions, and gives the parties a methodology they can both live with instead of relitigating it at every production.

04 — Privilege review disputes
Log volume, review methodology, claw-back, and the eternal fight over whether a privilege call was right — multiplied across hundreds of thousands of documents.
- The fight
- Challenges to privilege designations, the adequacy of a log, or the review process that produced it, frequently with in-camera review demanded.
- Why motion practice is slow
- Document-by-document review is exactly what a busy court cannot do at scale; the dispute stalls production for everyone.
- What a neutral does
- Reviews sampled or contested entries, sets a consistent standard, and resolves the calls — relieving the court of an unmanageable in-camera burden.

- FRCP 53 · CCP §§ 638–639
05 — Forensic inspection protocols
One party needs access to the other's systems or devices — and the protocol governing how that access happens is itself the dispute.
- The fight
- Demands to image devices or inspect systems collide with privacy, trade-secret, and proportionality objections.
- Why motion practice is slow
- The court is asked to design a technical access protocol it has neither the time nor the tooling to draft and supervise.
- What a neutral does
- Designs and supervises an inspection protocol — scope, tooling, chain of custody, and what the requesting party may and may not see — and serves as the neutral who actually runs it.

06 — Cross-border discovery
U.S. discovery obligations collide with foreign data-protection regimes — the GDPR, national blocking statutes, and the Hague Evidence Convention — when the ESI lives abroad.
- The fight
- Whether and how a party must produce ESI held overseas when foreign law restricts the transfer, and which regime controls the conflict.
- Why motion practice is slow
- The conflict-of-laws and comity analysis is fact-intensive and turns on how the data is actually stored and moved — questions a crowded docket rarely resolves quickly.
- What a neutral does
- Maps the data flows and structures a proportionate, staged production that respects both U.S. obligations and foreign-law constraints — mediating the transfer-mechanism fight before it stalls the case.

Procedural vehicles
The same fight can be routed three ways.
The right vehicle depends on the forum and what the parties will stipulate to.
Special Master under FRCP 53
In federal court, the court may appoint a Special Master to address pretrial matters — including discovery — that cannot be effectively and timely addressed by the judge. The order defines the master's duties, standard of review, and compensation.
Discovery referee under CCP §§ 638–639
In California, a court may appoint a discovery referee by the parties' agreement (§ 638) or, in defined circumstances, on its own motion (§ 639). The referee hears and determines the referred discovery disputes.
Forensic neutral & ESI mediator (stipulation)
Outside any appointment, parties can simply stipulate to a forensic neutral or ESI mediator — including within an arbitration — to design protocols or mediate the protocol fight before it hardens into a motion.
