Quashing or Modifying Subpoenas
Everything this chapter has taught so far enlarges the defendant's reach: the Sixth Amendment right to the government's help in compelling witnesses, the trial subpoena the clerk issues, the contempt power that backs it, and the document subpoena that reaches papers and objects. Rule 17(c)(2) is the counterweight. It provides that, on motion made promptly, the court may quash or modify the subpoena if compliance would be unreasonable or oppressive.1 The rule therefore has two conditions, a prompt motion and unreasonable or oppressive compliance, and two remedies. To quash a subpoena is to cancel it, so that nothing remains to be obeyed, while to modify it is to rewrite its terms and leave a narrower command in force.
The rule exists because a subpoena is a court order drafted by an interested party. The clerk issues a blank subpoena to the party who asks for it, and that party fills in the name, the time, the place, and the list of items, so the party decides what the recipient must do.2 The drafter bears none of the cost of compliance, the recipient bears all of it, and the order carries the court's authority and the contempt power described earlier in this chapter. A system built that way needs a point at which a judge can correct a demand that overreaches. The subpoena stays under the court's supervision for that reason, and as the Court noted in United States v. Calandra, the court may quash or modify a subpoena on motion if compliance would be unreasonable or oppressive.3
The rule has to be read against the constitutional weight on the other side. In Taylor v. Illinois the Court called the accused's right to present witnesses one of the most fundamental rights there is and an essential attribute of the adversary system itself, and it quoted the statement in United States v. Nixon that compulsory process must be available for evidence needed by either the prosecution or the defense.4 The same opinion added that the Compulsory Process Clause gives the accused an effective weapon that cannot be used irresponsibly.5 Taylor involved a discovery sanction rather than a subpoena, but its balance carries over: a defendant may demand evidence, and a witness need not submit to a demand that is abusive. Because the court can modify as well as quash, it can honor both interests at once by trimming a subpoena to what is legitimately needed, which keeps the defendant's access to the evidence and relieves the witness of the excess.
The rule appears in the paragraph governing subpoenas for documents, and its words on their face speak to a subpoena for papers and objects. Federal courts have nonetheless entertained motions to quash subpoenas that command testimony, apparently on the assumption that unreasonable or oppressive compliance is not a problem peculiar to documents.6 The two conditions of the rule are taken in turn below, beginning with the timing of the motion.
Promptness of the Motion
The first condition appears in the rule's opening words: the motion must be made promptly.7 The text sets no number of days, so promptness is measured against the schedule the subpoena itself creates, meaning the time between service and the date the witness must appear or produce, and the trial calendar behind that date. A motion filed soon after service, with ample time left before compliance is due, is prompt on any reading. A motion held until the return date or the day of trial is not, however strong its grounds.
The condition does two jobs. The functional one is that the judge needs time to decide. A court ruling in advance can hear the witness and the party who issued the subpoena, and the party can respond by agreeing to narrower terms or by serving a corrected subpoena, all before anyone has to comply. The incentive reason is subtler. An objection costs nothing to hold back, and a reluctant witness who waits until the last moment forces the court to choose between postponing the trial and enforcing a demand it has not examined. The party who issued the subpoena pays for either choice, because a defendant's access to evidence is worth little if the evidence arrives too late to be used. Requiring promptness removes the advantage of waiting.
Promptness also protects the witness. When the objection is presented by a motion in the district court, the witness gets a ruling before compliance is due, and a witness who loses the motion must comply or risk contempt.8 In the grand jury setting, an order rejecting the objection is ordinarily not itself appealable, and review comes only through an appeal from a contempt order.9 A witness who skips the motion gives up the chance to have the demand corrected in advance and faces the contempt power directly.
Two features keep this condition in proportion. Promptness is a condition of the rule's grant of power and does not by itself earn relief: a motion filed the day after service still fails if compliance would be neither unreasonable nor oppressive, which is the subject of the next section. In the other direction, a strong objection raised late does not satisfy the first condition, because the rule's power attaches to motions made promptly.
Unreasonable or Oppressive Compliance
The second condition is that compliance would be unreasonable or oppressive.11 The rule's word is or, so a demand need only be one or the other, and the focus falls on compliance, meaning what obeying the subpoena as written would require of the person who must obey it. The two words give a court two angles. Unreasonableness asks whether the demand is fairly tied to a legitimate need and no wider than that need, while oppressiveness asks how heavily the demand falls on the recipient. In United States v. R. Enterprises, a grand jury case, the Court observed that what is reasonable depends on context, so both words are applied to the facts of the particular subpoena rather than by formula.12
Breadth is the commonest sign of trouble. In United States v. Dionisio the Court recognized that the Fourth Amendment protects against a grand jury subpoena duces tecum that is too sweeping in its terms to be regarded as reasonable.13 In Trump v. Vance the Court noted that a subpoena recipient may generally challenge the subpoena on grounds permitted by state law, which usually include bad faith and undue burden or breadth.14 The same passage says that a court should use its inherent authority to quash or modify a subpoena if necessary to prevent the harm the recipient has shown, which ties the remedy to the problem and no further.15
Ordinary burden falls short of the standard. The Court has described the duty to give evidence as one that may be burdensome and even embarrassing, and it has held that the witness's personal interest must yield to the public's interest in full disclosure.16 Time and convenience are usually fixable without excusing compliance, since in Dionisio the Court quoted with approval the observation that if the time for appearance is inconvenient, this can generally be altered.17 The dividing line therefore runs between the cost every recipient bears in obeying a legitimate subpoena and a burden out of proportion to any legitimate need.
Once both conditions are satisfied, the rule says the court may quash or modify, which leaves both the decision to act and the choice of remedy to the judge. In United States v. Nixon the Court described enforcement of a pretrial subpoena duces tecum as resting in the sound discretion of the trial court, because necessity often turns on factual determinations, and it said an appellate court ordinarily will not disturb the trial court's finding absent arbitrariness or lack of record support.18 Within that discretion, the constitutional weight of the defendant's interest supports narrowing a subpoena before canceling it, because a modified subpoena keeps the evidence flowing while removing the excess. Quashing is the fitting remedy when no narrowing would cure the defect, as when the evidence shows the subpoena was issued in bad faith to harass the witness.
Students over-read this rule when they treat inconvenience as oppression. A witness who would prefer another week, or who finds the testimony unpleasant, has described the ordinary burden of a subpoena, and the rule is aimed at demands that overreach or crush.
Promptness of the Motion
The first condition appears in the rule's opening words, which let the court act only on a motion "made promptly."20 Neither those words nor the rest of the rule says how many days the recipient has, so promptness has to be judged against the schedule the subpoena itself creates. That schedule runs from the moment of service to the date the witness must appear or produce, and the trial calendar stands behind that date. A recipient who objects soon after being served, with time still left before compliance is due, has moved promptly on any sensible reading. A recipient who holds the objection until the return date, or until after failing to appear, has not.
The condition does two jobs, and each explains what promptness looks like in practice. The functional job is to give the court time to rule. The judge may need to hear from the witness and from the party who issued the subpoena, and that party may respond by agreeing to narrower terms, serving a corrected subpoena, or looking for the evidence another way. Every one of those adjustments is available only while trial does not yet depend on the evidence. The incentive job is subtler. An objection costs nothing to hold back, and a recipient who waits gains leverage, because a late objection leaves the court choosing between disrupting the trial and enforcing a subpoena that might have been repaired earlier. Tying the court's power to a prompt motion removes any reward for waiting, and it protects the party who issued the subpoena, whose access to evidence means little if the dispute over it surfaces only when the evidence is needed.
Two cautions keep this condition in proportion. The rule gives no deadline, so an answer that recites a fixed number of days after service has added something the text does not contain. The rule also does not announce a specific consequence for a late motion, and the safest statement is that the court may treat such a motion as failing the rule's condition. In the other direction, promptness is only the first condition and earns no relief by itself, because a motion filed the day after service still fails unless compliance would be unreasonable or oppressive, which is the subject of the next section. Students lose points here when they let the strength of the objection stand in for its timing, since a strong objection raised late still has not been made promptly.
Unreasonable or Oppressive Compliance
Once a motion has been made promptly, the court turns to the second condition of Rule 17(c)(2), which allows it to quash or modify the subpoena "if compliance would be unreasonable or oppressive."22 The rule joins the two words with or, so a demand that meets either one opens the court's power to act. The inquiry focuses on compliance, meaning what obeying the subpoena as written would require of the person who must obey it. Unreasonableness asks whether the demand is tied to a legitimate need and drawn no wider than that need. Oppressiveness asks how heavily the demand presses on the one who must comply, and the two can come apart, because a request can be entirely relevant and still be crushing to meet. The sections below take each word in turn, then the line between ordinary burden and the kind the rule addresses, and finally the choice of remedy.
The standard does not explain itself, and the yardstick for it depends on the setting. In United States v. R. Enterprises the Court observed that what is reasonable depends on context, and it described United States v. Nixon as having defined reasonableness for a subpoena used in a jury trial.23 Nixon required the party seeking pretrial production to show that the material is evidentiary and relevant, that it cannot reasonably be obtained sooner by diligence, that advance inspection is needed to prepare for trial without delay, and that the request is made in good faith and is no fishing expedition.24 R. Enterprises then held that this trial standard does not govern grand jury subpoenas, because a grand jury often cannot know in advance which offense it will charge or what will prove relevant.25 The grand jury decisions discussed next therefore illustrate what makes a demand unreasonable by analogy, and they do not supply the test for a trial subpoena.
Breadth is the commonest sign of an unreasonable demand. In Hale v. Henkel the Court held that a grand jury subpoena duces tecum was too sweeping to be reasonable under the Fourth Amendment, because it demanded all of a corporation's contracts and correspondence with six other companies, along with reports, accounts, and letters from many more, reaching back to the corporation's founding, without naming a single particular contract.26 United States v. Calandra likewise recognized that the grand jury's subpoena power has limits, that a sweeping subpoena duces tecum will be disallowed, and that judicial supervision is exercised to prevent the wrong before it occurs.27 Lower federal courts applying the overbreadth standard ask whether the subpoena commands only things relevant to the inquiry, describes them with reasonable particularity, and reaches back over only a reasonable period of time.28 The Hale subpoena shows each failure at once, since it named no particular document, covered a wide field of companies, and set no limit in time.
Oppressiveness is a separate ground, and it matters most when the request itself is legitimate. A demand may be relevant and still oppressive because of the cost and disruption of collecting and handing over large quantities of documents, and the usual response is to require narrowing by time period or category of documents.29 Courts have also treated as oppressive demands that would chill confidential relationships serving the public interest, such as a subpoena that would have required a wire-transfer company to identify customers who made large transfers, or one that would have required a police department to produce internal-investigation statements given under a promise of confidentiality.30 Justice Stevens, concurring in R. Enterprises, described the rule as a balance between the burden of compliance and the interest in obtaining the material, so that a heavier burden calls for a stronger showing of probable relevance.31 That concurrence arose in a grand jury case, but its weighing explains why the rule has two words: one measures the demand against the need, and the other measures what the demand costs.
Not every burden qualifies. The Court has acknowledged that the duty to give evidence may be burdensome and even embarrassing, and it has held that the witness's personal interest must yield to the public's interest in full disclosure.32 The reason follows from what a subpoena is. Every subpoena costs its recipient some time and effort, so if cost alone were enough, every subpoena could be defeated, and the accused's compulsory process would fail exactly when evidence was needed. In Taylor v. Illinois the Court quoted the statement in Nixon that compulsory process must be available for evidence needed by either the prosecution or the defense, and it called the right to present witnesses one of the most fundamental an accused has.33 The rule therefore reaches only burdens out of proportion to any legitimate need, and it leaves the ordinary cost of obeying a proper subpoena in place.
When a condition is met, the rule says the court may quash or modify, which leaves both the decision to act and the choice of remedy to the judge. In Nixon the Court described enforcement of a pretrial subpoena duces tecum as resting in the sound discretion of the trial court, because necessity often turns on factual determinations, and it said an appellate court ordinarily will not disturb that finding absent arbitrariness or lack of record support.34 Within that discretion, modification is the natural first remedy for a subpoena that is overbroad but partly legitimate, because quashing would throw away the demand that is proper, while narrowing its scope, time, or place removes only the excess. Quashing fits when no narrowing could cure the defect, as when the demand serves no legitimate purpose at all. R. Enterprises made a similar point in the grand jury setting, noting that grand juries may not conduct arbitrary fishing expeditions or select targets out of malice or an intent to harass.35
Students most often go wrong by treating ordinary inconvenience as oppression and by assuming that quashing is the only remedy. On facts like the twenty-year subpoena, the answer is modification. On facts like the single designated contract, the answer is no relief at all.
