`AO 88A (Rev. 2/ ) Subpoena to Testify at a Deposition in a Civil Action (Page 3)
`Federal Rule of Civil Procedure 45 (c), (d), (e), and (g) (Effective 12/1/13)
`(c) Place of Compliance.
`(1) For a Trial, Hearing, or Deposition. A subpoena may command a
`person to attend a trial, hearing, or deposition only as follows:
`(A) within 100 miles of where the person resides, is employed, or
`regularly transacts business in person; or
`(B) within the state where the person resides, is employed, or regularly
`transacts business in person, if the person
`(i) is a party or a party’s officer; or
`(ii) is commanded to attend a trial and would not incur substantial
`expense.
`(2) For Other Discovery. A subpoena may command:
`(A) production of documents, electronically stored information, or
`tangible things at a place within 100 miles of where the person resides, is
`employed, or regularly transacts business in person; and
`(B) inspection of premises at the premises to be inspected.
`(d) Protecting a Person Subject to a Subpoena; Enforcement.
`(1) Avoiding Undue Burden or Expense; Sanctions. 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. The court for the district where compliance is required must
`enforce this duty and impose an appropriate sanction—which may include
`lost earnings and reasonable attorney’s fees—on a party or attorney who
`fails to comply.
`(2) Command to Produce Materials or Permit Inspection.
`(A) Appearance Not Required. A person commanded to produce
`documents, electronically stored information, or tangible things, or to
`permit the inspection of premises, need not appear in person at the place of
`production or inspection unless also commanded to appear for a deposition,
`hearing, or trial.
`(B) Objections. A person commanded to produce documents or tangible
`things or to permit inspection may serve on the party or attorney designated
`in the subpoena a written objection to inspecting, copying, testing, or
`sampling any or all of the materials or to inspecting the premises—or to
`producing electronically stored information in the form or forms requested.
`The objection must be served before the earlier of the time specified for
`compliance or 14 days after the subpoena is served. If an objection is made,
`the following rules apply:
`(i) At any time, on notice to the commanded person, the serving party
`may move the court for the district where compliance is required for an
`order compelling production or inspection.
`(ii) These acts may be required only as directed in the order, and the
`order must protect a person who is neither a party nor a party’s officer from
`significant expense resulting from compliance.
`(3) Quashing or Modifying a Subpoena.
`(A) When Required. On timely motion, the court for the district where
`compliance is required must quash or modify a subpoena that:
`(i) fails to allow a reasonable time to comply;
`(ii) requires a person to comply beyond the geographical limits
`specified in Rule 45(c);
`(iii) requires disclosure of privileged or other protected matter, if no
`exception or waiver applies; or
`(iv) subjects a person to undue burden.
`(B) When Permitted. To protect a person subject to or affected by a
`subpoena, the court for the district where compliance is required may, on
`motion, quash or modify the subpoena if it requires:
`(i) disclosing a trade secret or other confidential research, development,
`or commercial information; or
`(ii) disclosing an unretained expert’s opinion or information that does
`not describe specific occurrences in dispute and results from the expert’s
`study that was not requested by a party.
`(C) Specifying Conditions as an Alternative. In the circumstances
`described in Rule 45(d)(3)(B), the court may, instead of quashing or
`modifying a subpoena, order appearance or production under specified
`conditions if the serving party:
`(i) shows a substantial need for the testimony or material that cannot be
`otherwise met without undue hardship; and
`(ii) ensures that the subpoenaed person will be reasonably compensated.
`(e) Duties in Responding to a Subpoena.
`(1) Producing Documents or Electronically Stored Information. These
`procedures apply to producing documents or electronically stored
`information:
`(A) Documents. A person responding to a subpoena to produce documents
`must produce them as they are kept in the ordinary course of business or
`must organize and label them to correspond to the categories in the demand.
`(B) Form for Producing Electronically Stored Information Not Specified.
`If a subpoena does not specify a form for producing electronically stored
`information, the person responding must produce it in a form or forms in
`which it is ordinarily maintained or in a reasonably usable form or forms.
`(C) Electronically Stored Information Produced in Only One Form. The
`person responding need not produce the same electronically stored
`information in more than one form.
`(D) Inaccessible Electronically Stored Information. The person
`responding need not provide discovery of electronically stored information
`from sources that the person identifies as not reasonably accessible because
`of undue burden or cost. On motion to compel discovery or for a protective
`order, the person responding must show that the information is not
`reasonably accessible because of undue burden or cost. If that showing is
`made, the court may nonetheless order discovery from such sources if the
`requesting party shows good cause, considering the limitations of Rule
`26(b)(2)(C). The court may specify conditions for the discovery.
`(2) Claiming Privilege or Protection.
`(A) Information Withheld. A person withholding subpoenaed information
`under a claim that it is privileged or subject to protection as trial-preparation
`material must:
`(i) expressly make the claim; and
`(ii) describe the nature of the withheld documents, communications, or
`tangible things in a manner that, without revealing information itself
`privileged or protected, will enable the parties to assess the claim.
`(B) Information Produced. If information produced in response to a
`subpoena is subject to a claim of privilege or of protection as
`trial-preparation material, the person making the claim may notify any party
`that received the information of the claim and the basis for it. After being
`notified, a party must promptly return, sequester, or destroy the specified
`information and any copies it has; must not use or disclose the information
`until the claim is resolved; must take reasonable steps to retrieve the
`information if the party disclosed it before being notified; and may promptly
`present the information under seal to the court for the district where
`compliance is required for a determination of the claim. The person who
`produced the information must preserve the information until the claim is
`resolved.
`(g) Contempt.
`The court for the district where compliance is required—and also, after a
`motion is transferred, the issuing court—may hold in contempt a person
`who, having been served, fails without adequate excuse to obey the
`subpoena or an order related to it.
`For access to subpoena materials, see Fed. R. Civ. P. 45(a) Committee Note (2013).
