Begin with the governing doctrine
Discovery exchanges nonprivileged information relevant to claims or defenses and proportional to case needs. Proportionality considers stakes, amount, access, resources, importance, and burden versus likely benefit; discoverability is not identical to admissibility. Privilege, work product, protective orders, supplementation, preservation, electronically stored information, and sanctions use separate rules. A subpoena commands a nonparty or party witness under Rule Forty-Five and carries issuing, service, geographic, objection, burden, compliance, and enforcement protections.
Pin discovery scope
The official rule limits discovery to nonprivileged, relevant, proportional matter. Verbatim official-source text: “Parties may obtain discovery regarding any nonprivileged matter that is relevant to any party's claim or defense and proportional to the needs of the case, considering” Source: Fed. R. Civ. P. 26(b)(1); https://www.uscourts.gov/sites/default/files/document/federal-rules-of-civil-procedure.pdf; official-source fixture (not neochart).
Pin proportionality factors
The official text supplies the proportionality considerations rather than a generic burden label. Verbatim official-source text: “the importance of the issues at stake in the action, the amount in controversy, the parties' relative access to relevant information, the parties' resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit.” Source: Fed. R. Civ. P. 26(b)(1); https://www.uscourts.gov/sites/default/files/document/federal-rules-of-civil-procedure.pdf; official-source fixture (not neochart).
Pin subpoena burden protection
The official rule requires reasonable steps to avoid undue burden or expense on a subpoenaed person. Verbatim official-source text: “A party or attorney responsible for issuing and serving a subpoena must take reasonable steps to avoid imposing undue burden or expense on a person subject to the subpoena.” Source: Fed. R. Civ. P. 45(d)(1); https://www.uscourts.gov/sites/default/files/document/federal-rules-of-civil-procedure.pdf; official-source fixture (not neochart).
Pin the synthetic fact pattern
A synthetic request seeks five years of messages, databases, model versions, logs, and devices from a party and a nonparty. The subpoena packet records court, command, notice, server, recipient, fees, place, form, objections, production, burden evidence, and preservation events.
Work the application
The request first enters privilege, relevance, and claim-or-defense scope, then each proportionality factor. The model does not decide proportionality by document count alone. ESI stages preserve sources, search terms, review, production form, metadata, and loss. The subpoena path separately verifies issuance, notice, service, place of compliance, tender, undue burden, objections, motions, and enforcement, ending in human review.
Read the populated procedure record
The folded subpoena packet contains request text, custodians, systems, date ranges, privilege log, proportionality facts, ESI workflow, subpoena form, service, fees, geography, objections, production, burden, sanctions predicates, and handoff rows. The rendered record contains 14 populated rows.

Read the complete record
The complete record keeps sources, stated facts, and questions for review separate. Authority records: NeoChart and official-source fixtures. Fed. R. Civ. P. 26(b)(1) source 1: Pin discovery scope. Fed. R. Civ. P. 26(b)(1) source 2: Pin proportionality factors. Fed. R. Civ. P. 45(d)(1) source 3: Pin subpoena burden protection. Synthetic facts: Classroom facts only. Request: Party requests five years of messages, databases, models, logs, and devices. Custodians: Party and nonparty witnesses have different systems and burdens. Subpoena: Issuing court, command, service, place of compliance, fees, notice, objections, and production are recorded. Application trace: Elements, stages, and unknowns. Scope: Privilege, relevance, claim or defense, proportionality, and protective orders are separate. ESI: Preservation, collection, processing, search, review, production, form, metadata, and loss need a protocol. Nonparty: Rule Forty-Five issuing, service, place, burden, objection, motion, and enforcement fields apply. Sanctions: Duty, control, loss, reasonable steps, prejudice, intent, notice, and remedy require source-specific proof.
Narrow summary
Discovery scope, proportionality, privilege, ESI, and subpoena protection are distinct records; preserve evidence and challenge burdens through the governing rule.
