MAY, Justice. 

Subpoenas are powerful tools. By serving subpoenas, private parties and 

their attorneys can compel free citizens to appear at specified places, give sworn 

testimony, produce documents, and more. But with this power comes 

responsibility. See, e.g., 9A Charles Alan Wright & Arthur R. Miller, Federal 

Practice and Procedure § 2453, at 396 (3d ed. 2008) (“[T]he lawyer’s . . . power to 

issue subpoenas is accompanied by . . . professional responsibility with regard 

to using it appropriately . . . .”). An attorney or party who serves a subpoena 

“must take reasonable steps to avoid imposing undue burden or expense on a 

person subject to the subpoena.” Iowa R. Civ. P. 1.1701(4)(a). “The issuing court 

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.” Id. And “[o]n timely motion, the issuing court must quash or modify a 

subpoena that . . . [s]ubjects a person to undue burden.” Id. r. 1.1701(4)(d)(1)(4). 

In this case, a plaintiff in a Louisiana products-liability suit used Iowa’s 

interstate discovery procedures to serve subpoenas on Dethmers Manufacturing 

Company, an Iowa firm. See Iowa R. Civ. P. 1.1702 (permitting parties to foreign 

proceedings to issue subpoenas in Iowa). Dethmers was not (and is not) a party 

in the Louisiana suit. And Dethmers has no direct interest in the suit. Even so, 

the subpoenas commanded Dethmers to provide twenty-two categories of 

documents and testimony. Many of those categories are extraordinarily broad. 

Fairly read, the subpoenas required Dethmers to produce every document that 

has anything to do with its trailer-coupling business—and then to also provide 
3 

sworn testimony about every facet of that business. Dethmers moved to quash 

the subpoenas. The district court declined. Dethmers appeals. 

We conclude that these subpoenas imposed undue burdens on Dethmers. 

Dethmers’s motion to quash the subpoenas should have been granted. We 

reverse and remand with instructions. 

I. Background Facts and Proceedings. 

On November 22, 2016, Tanika Adams was driving an SUV in Louisiana. 

Adams was pulling a U-Haul trailer. Adams’s SUV was equipped with a hitch 

ball, and the trailer was equipped with a coupler. The coupler attached the trailer 

to the SUV’s hitch ball. 

While Adams was traveling west on Interstate 10, the coupler became 

detached from the hitch ball. So Adams pulled the SUV to the right shoulder. 

But part of the trailer remained in the travel lane. 

Tharun Mittapalli and two friends were also driving west on Interstate 10. 

They pulled over and tried to help Adams. 

Meanwhile, a tractor trailer was also headed west on Interstate 10. It 

struck the U-Haul trailer, the SUV, and the people. Mittapalli was seriously 

injured. His accrued medical expenses exceed $1.2 million. Adams was also 

seriously injured. One of Mittapalli’s friends was killed. 

Mittapalli sued U-Haul and others in Louisiana state court. Mittapalli 

claims that a defect in the coupler caused the detachment. More specifically, 
4 

Mittapalli claims that the coupler was unreasonably dangerous because of a 

design defect.1 

Under Louisiana law, Mittapalli’s unreasonably-dangerous-design claim 

requires proof that “at the time the product left its manufacturer’s control[,] . . . 

[t]here existed an alternative design for the product that was capable of 

preventing the claimant’s damage.” La. Stat. Ann. § 9:2800.56(1) (2017). It also 

requires proof that “at the time the product left its manufacturer’s control[,] . . . 

[t]he likelihood that the product’s design would cause the claimant’s damage and 

the gravity of that damage outweighed the burden on the manufacturer of 

adopting such alternative design and the adverse effect, if any, of such 

alternative design on the utility of the product.” Id. § 9:2800.56(2). 

Mittapalli believes that Dethmers has information that could help him 

meet these requirements. Dethmers designs, manufactures, and sells couplers. 

And although Dethmers did not manufacture the coupler involved in the 

collision,2 Dethmers has sold couplers to U-Haul. Specifically, Mittapalli claims 

that “after the catastrophic incident, U-Haul began to implement the Dethmers 

EZ Latch Coupler (which U-Haul deems the ‘Drop & Tow Automatic Coupler’) 

into their fleet of tow trailers.” And Mittapalli believes that there are important 

differences between (1) the coupler that was involved in the accident and (2) the 

Dethmers-designed EZ Latch Coupler. Specifically, Mittapalli believes that 

Dethmers’s design was (to paraphrase the Louisiana statute) a feasible 

1Mittapalli made other claims, too. But they are not relevant here. 

2Nor does Dethmers have any other involvement in Mittapalli’s Louisiana case.

alternative design that probably would have prevented the detachment and 

subsequent injuries. 

So Mittapalli filed a “Motion for Issuance of a Foreign Subpoena Duces 

Tecum” and a “Motion for Issuance of a Subpoena for Deposition” in Iowa district 

court. The court opened a separate file for each. Mittapalli then served two 

subpoenas on Dethmers: one for documents and one for deposition testimony. 

The document subpoena required Dethmers to produce twenty-two categories of 

“documents”—a term that, according to the subpoena, includes “writings, 

drawings, graphs, charts, photographs, phone records, computer generated or 

stored data, electronically stored information, and other data compilations from 

which information can be obtained, translated, if necessary, by [Dethmers] 

through detection devices into reasonably usable form.” The deposition 

subpoena required Dethmers to produce a “duly authorized corporate 

representative” who “must have sufficient knowledge and qualifications to testify 

regarding” the same twenty-two categories. Here are the twenty-two categories, 

verbatim: 

1. The general scope of Dethmer/Demco’s business as it relates to 

the design, development, and manufacturing of trailer coupling

Dethmers responded by moving to quash the subpoenas. Dethmers argued 

that compliance would impose undue burden on Dethmers, require production 

of protected trade secrets and other confidential commercial information, and 

require Dethmers’s employees to serve as unretained experts. Dethmers also 

noted that Mittapalli could obtain the information that he needed from other 

sources, including discovery requests in the Louisiana case, public records, and 
8 

Mittapalli’s own retained expert. As support for its motion, Dethmers filed an 

affidavit of Kevin Ten Haken, Dethmers’s Executive Vice President. Parts of the 

affidavit are reproduced here: 

10. Most of the categories of topics and documents described in the 

applications are addressed to trade secret, proprietary and 

confidential information of Dethmers. The following categories 

seek information which Dethmers keeps in confidence and does 

not allow to be disseminated to persons outside of its business 

operations: 

. . . . [here, the affidavit recited verbatim the text of requests 1–3, 

6–8, and 10–22]. 

11. The trailer parts business is highly competitive and involves 

margins that are easily affected by changes in sales. The 

information described in the categories listed above would, in my 

opinion, provide our competitors with an undue advantage if 

disseminated to them, and could affect our sales of couplers. 

12. To the extent that we can understand what is being asked of us, 

the information in the above categories would require substantial 

expense and man-hours to gather. Gathering this information 

would involve examination of many physical files and computer 

files. Dethmers’ business records are not kept in a way that 

corresponds with these categories. Gathering these records 

would adversely impact Dethmers’ business operations and affect 

Dethmers’ income by devoting man-hours to useless activity 

instead of profitable activity. 

Mittapalli resisted. Dethmers then filed a supplemental affidavit. In it, Ten 

Haken further emphasized the competitive nature of the coupler business and 

the confidential and proprietary nature of much of the information sought. 

At a hearing, the district court received exhibits and heard argument on 

Dethmers’s motions. A few days later, the court issued an order denying 

Dethmers’s motion to quash but directing the parties to “jointly tender a 

proposed” protective order for the court’s consideration. 
9 

Dethmers moved to reconsider. The court again declined to quash the 

subpoenas. This appeal followed. In his appellee’s brief, Mittapalli announced 

that he has now settled with U-Haul. Now, Mittapalli says, the Louisiana case is 

focused on Horizon Global Americas, Inc., who allegedly manufactured the trailer 

coupler that failed. 

II. Analysis. 

Dethmers argues that the district court abused its discretion by refusing 

to quash the subpoenas. We agree. 

A. Standard of Review. Generally speaking, “[w]e review discovery rulings 

for abuse of discretion.” Vaccaro v. Polk County, 983 N.W.2d 54, 57 (Iowa 2022). 

“A ruling based on an erroneous interpretation of a discovery rule can constitute 

an abuse of discretion.” Id. (quoting Mitchell v. City of Cedar Rapids, 926 N.W.2d 

222, 227 (Iowa 2019)). We review the “interpretation of our rules of civil 

procedure for errors at law.” Reis v. Iowa Dist. Ct., 787 N.W.2d 61, 66 

(Iowa 2010). 

B. Jurisdiction. Before reaching the merits, we must consider a 

jurisdictional issue. Generally speaking, civil litigants have a right of appeal only 

from final orders or judgments. Iowa R. App. P. 6.103(1). But see, e.g., id. (noting 

exceptions). An order is “final” if it “conclusively adjudicates all of the rights of 

the parties,” Richers v. Marsh & McLennan Grp. Assocs., 459 N.W.2d 478, 480 

(Iowa 1990), and leaves the district court with “nothing more to do than execute 

that order,” In re M & S Grading, Inc., 526 F.3d 363, 369 (8th Cir. 2008). See In re 

Marriage of Brown, 776 N.W.2d 644, 648 (Iowa 2009) (“It must leave nothing 
10 

more to be done in order to effectuate the court’s disposition of the matter.” 

(quoting Rohrbeck v. Rohrbeck, 566 A.2d 767, 774 (Md. 1989))). Ordinarily, 

discovery orders don’t fit this definition. They don’t resolve all disputes before 

the court. They don’t end the litigation. Rather, in most cases, discovery orders 

are just small steps in a litigation odyssey that cannot end without a trial, 

dispositive motion, or voluntary dismissal. So discovery orders are usually 

considered interlocutory—not final—and they may not be appealed as of right. 

Rather, a “party aggrieved” by a discovery order usually has to apply “for 

permission” to pursue an interlocutory appeal. Iowa R. App. P. 6.104(1); see, e.g.,

Vaccaro, 983 N.W.2d at 56–57 (addressing discovery issues through an 

interlocutory appeal). 

But this case is unusual. Here we are dealing with special actions for 

interstate discovery under Iowa Rules of Civil Procedure 1.1701 and 1.1702. In 

these actions, discovery is not secondary. Rather, in these special actions, 

discovery is the only issue before our courts. More specifically, in these cases, 

the only question is whether and to what extent Dethmers must comply with 

Mittapalli’s subpoenas. The district court resolved this issue by refusing to quash 

the subpoenas. This refusal amounted to a final order. So Dethmers was entitled 

to appeal. 

Of course, we recognize that “[a] ruling is not final when the trial court 

intends to do something further to signify its final adjudication of the case.” In re 

Marriage of McCreary, 276 N.W.2d 399, 400 (Iowa 1979). We also recognize that 

in its initial order denying Dethmers’s motion to quash, the court directed the 
11 

parties to “jointly tender a proposed” protective order for the court’s 

consideration. The resulting protective order could have altered Dethmers’s 

obligations under the subpoenas. In fact, the court noted that “a protective order 

could appropriately mitigate unreasonable expenditures of time and money 

expended for compliance” with the subpoenas. 

But in its ruling on Dethmers’s motion to reconsider, the court 

“suspended” the protective-order requirement “pending disposition of Dethmers’ 

planned appeal.” We read this to mean that once the court denied the motion to 

reconsider, the court did not intend to take any further action. This confirms our 

view that Dethmers appealed from a final order. 

C. Merits. Different provisions of law authorize different kinds of 

subpoenas. For instance, Iowa Code section 11.51 gives the state auditor “power 

to issue subpoenas of all kinds.” Sand v. Doe, 959 N.W.2d 99, 105 (Iowa 2021) 

(quoting Iowa Code § 11.51 (2020)). Other statutes grant subpoena powers to 

various other government actors, such as the ombudsman, Iowa Code § 2C.9 

(2021), and the attorney general, id. § 714.16. 

In this case, we consider subpoenas authorized by Iowa Rules of Civil 

Procedure 1.1701 and 1.1702. These rules provide powerful tools for civil 

litigants. By issuing subpoenas, attorneys in civil cases can require free citizens 

to produce their private documents, testify in depositions, appear at hearings 

and trials, and more. 

As noted, though, rule 1.1701 includes important protections for persons 

subject to subpoenas. Under subsection 4(a), “[a] party or attorney responsible 
12 

for issuing and serving a subpoena must take reasonable steps to avoid imposing 

undue burden or expense on a person subject to the subpoena.” Iowa R. Civ. P. 

1.1701(4)(a) (emphasis added). And subsection 4(d)(1)(4) provides that “[o]n 

timely motion, the issuing court must quash or modify a subpoena that . . . 

[s]ubjects a person to undue burden.” Id. r. 1.1701(4)(d)(1)(4) (emphasis added). 

But how should the court decide whether a subpoena imposes “undue 

burden”? The district court applied a four-factor inquiry described in State ex rel. 

Miller v. Publishers Clearing House, Inc., 633 N.W.2d 732, 738 (Iowa 2001) 

(en banc). We do not believe that authority is especially relevant here. Miller

involved investigative subpoenas issued by the attorney general as an exercise 

of his3 “plenary investigative powers” under our consumer fraud statute, Iowa 

Code section 714.16. Id. at 734–35. Miller does not govern the (very different) 

subpoenas at issue here, which are governed by rule 1.1701, and may be issued 

by any attorney in almost any civil case. 

Instead, we adopt a test that federal courts apply under Federal Rule of 

Civil Procedure 45, on which rule 1.1701 is modeled. Under this test, “[t]o 

determine whether a subpoena presents an undue burden,” the court should 

weigh the following factors: “(1) [the] relevance of the information requested; 

(2) the need of the party for the documents; (3) the breadth of the document 

request; (4) the time period covered by the request; (5) the particularity with 

which the party describes the requested documents; and (6) the burden

104 Fed. Cl. 647, 656 (2012). 

We mention three additional points that courts should bear in mind when 

applying this test. First, we emphasize the need to protect nonparties. See, e.g.,

Rossman v. EN Eng’g, LLC, 467 F. Supp. 3d 586, 590 (N.D. Ill. 2020) (“[C]ourts 

have consistently held that ‘non-party status’ is a significant factor to be 

considered in determining whether the burden imposed by a subpoena is 

undue.”); Whitlow v. Martin, 263 F.R.D. 507, 512 (C.D. Ill. 2009) (“Non-party 

status is a significant factor to be considered in determining whether the burden 

imposed by a subpoena is undue.”). While parties to a lawsuit must accept the 

burden of discovery “as a natural concomitant of modern civil litigation[,] . . . 
14 

[n]on-parties have a different set of expectations.” Cusumano v. Microsoft Corp., 

162 F.3d 708, 717 (1st Cir. 1998). Because they are “strangers” to the dispute—

they have “no dog in [the] fight”—they should not be exposed to the same 

burdens as the parties. Va. Dep’t of Corr. v. Jordan, 921 F.3d 180, 189 (4th Cir. 

2019) (alteration in original) (quoting Cusumano, 162 F.3d at 717); see also id. 

at 194 (noting that nonparties “deserve special solicitude”). “[C]oncern for the 

unwanted burden thrust upon non-parties is a factor entitled to special weight” 

when applying the test. Miscellaneous Docket Matter No. 1 v. Miscellaneous 

Docket Matter No. 2, 197 F.3d 922, 927 (8th Cir. 1999) (quoting Cusumano, 

162 F.3d at 717). 

Second, although the test includes several factors, this does not mean that 

all factors must carry equal weight in every case. One factor (or two) could be 

determinative, depending on the case. For instance, if a subpoena requests 

documents that have no relevance to a litigated issue, the request automatically 

fails. Similarly, if the requesting party fails to show that they need to obtain 

documents or information from a nonparty, the subpoena may be quashed 

entirely. Rossman, 467 F. Supp. 3d at 590 (“A non-party subpoena seeking 

information that is readily available from a party through discovery may be 

quashed as duplicative or cumulative.”); Amini Innovation Corp. v. McFerran 

Home Furnishings, Inc., 300 F.R.D. 406, 410 (C.D. Cal. 2014) (collecting cases 

and noting that “[c]ourts are particularly reluctant to require a non-party to 

provide discovery that can be produced by a party”). So parties who impose 

subpoena obligations on nonparties must be prepared to show that they couldn’t 
15 

have satisfied their needs by other means, such as discovery requests to “one of 

the parties to the litigation.” Jordan, 921 F.3d at 189; see Precourt, 280 F.R.D. 

at 467 (“If the party seeking the information can easily obtain the same 

information without burdening the nonparty, the court will quash the 

subpoena.”). 

Finally, we emphasize that attorneys and parties must frontload their 

efforts to “avoid imposing undue burden or expense on a person subject to the 

subpoena.” Iowa R. Civ. P. 1.1701(4)(a); see, e.g., Mod. Plastics Corp., 890 F.3d 

at 251 (“[F]ailure narrowly to tailor a subpoena may be a ground for sanctions 

. . . .” (quoting Legal Voice v. Stormans Inc., 738 F.3d 1178, 1185 (9th Cir. 

2013))). It is not enough to say that although a subpoena was obviously too broad 

when it was served, its onerous demands were just a starting point for a future 

negotiation that would likely lead the issuing attorneys to settle for less. We reject 

strategies of this kind. Subpoenas carry the power of the court. See, e.g., 

Fed. R. Civ. P. 45 advisory committee’s note to 1991 amendment (“[D]efiance of 

a subpoena is . . . an act in defiance of a court order and exposes the defiant 

witness to contempt sanctions.”). We must avoid any abuse of that power. To the 

extent practicable, then, subpoenas must be reasonable—they must not be 

unduly burdensome—when they are served. And so, an issuing party must 

properly tailor its subpoenas before they are served. See Jordan, 921 F.3d at 190 

(“A nonparty should not have to do the work of tailoring a subpoena to what the 

requesting party needs; the requesting party should have done that before serving 

it.” (emphasis added)). 
16 

With these principles in mind, we consider the document subpoena that 

Mittapalli served on nonparty Dethmers. We begin by considering the “relevance” 

of the documents requested. Leonard, 38 F.4th at 489; Mod. Plastics Corp., 

890 F.3d at 251. Here we generally agree with the district court that Mittapalli’s 

requests are relevant to the underlying Louisiana litigation. To prove his 

defective-design claim, Mittapalli must show that a safer coupler design was 

available and feasible. Dethmers’s EZ Latch coupler could qualify as a safer 

alternative. And Mittapalli’s subpoena seeks documents and information about 

Dethmers and its design, manufacture, and sale of the EZ Latch coupler. These 

topics are at least minimally relevant to Mittapalli’s defective-design claim.4

But even though Mittapalli can pass the relevance bar, all other factors 

weigh against enforcement of his subpoena. As noted, the requesting party’s 

“need” to obtain documents from the nonparty is an important factor. See 

Jordan, 921 F.3d at 188–90. When we consider what a requesting party “needs,” 

we must “consider what information is available to the requesting party from 

other sources.” Id. at 189. Like the United States Court of Appeals for the Fourth 

Circuit, we think “the requesting party should be able to explain why it cannot 

obtain the same information, or comparable information that would also satisfy 

4In his appellee’s brief, Mittapalli announced that he has now settled with U-Haul. 

Accordingly, Mittapalli now concedes that some of his original requests—particularly, those 

focused on U-Haul—are no longer relevant to the Louisiana case. Our first task, though, is to 

decide whether the district court abused its discretion by refusing to quash the subpoenas. We 

make that determination based on the record that was before the district court. In that record, 

U-Haul is front and center.

its needs, from one of the parties to the litigation—or, in appropriate cases, from 

other [nonparties] that would be more logical targets for the subpoena.” Id.

Mittapalli has not shown need. The record does not show whether 

Mittapalli has obtained—or could have obtained—the same documents and 

information from other sources, such as discovery in the Louisiana case or the 

assistance of retained experts. So Mittapalli has failed to show that he needs to 

impose any burdens on Dethmers, a nonparty. This failure is fatal to Mittapalli’s 

subpoena. 

We recognize that the district court looked at the matter differently. The 

court believed 

Dethmers’ argument that Plaintiff can obtain what he needs 

from U-Haul ignores the adversary relationship inherent between 

opposing litigants and the distinct possibility of lack of full 

disclosure. In a case of this magnitude, Plaintiff should not be 

required to seek the very information he needs to prove his case from 

the user of the product, his opposition [U-Haul], when it is available 

from the presumed neutral designer and manufacturer [Dethmers]. 

We disagree for three reasons. First, we note the district court’s focus on 

the “magnitude” of the case—an apparent reference to the extraordinary 

damages suffered by the plaintiffs in the Louisiana case. We must remember, 

though, that Dethmers is not a party to that case. Dethmers cannot recover—

and it will not be liable for—any damages assessed. So when we consider whether 

a subpoena imposes “undue burden” on Dethmers, the magnitude of the 

damages involved has relatively less importance. 

Second, and relatedly, we disagree with the court’s general approach to 

Dethmers’s nonparty status. In the district court’s view, it was better to impose 
18 

discovery burdens on Dethmers because it is a “presumed neutral” nonparty and 

not an “opposing litigant.” As explained, though, we think the opposite approach 

is better. To the extent practicable, the burdens of discovery should fall on 

parties—not on nonparties like Dethmers. 

Finally, we note that the district court believed Mittapalli’s needs could not 

be fulfilled through adversarial discovery because of the “distinct possibility of 

lack of full disclosure” by parties to the Louisiana case. But no record evidence 

suggests that any party to the Louisiana lawsuit has violated any discovery 

obligation. And, again, we think it was Mittapalli’s burden to demonstrate his 

need to impose burdens upon a nonparty by showing that party-vs.-party 

discovery could not produce what he is now asking from Dethmers. Jordan, 

921 F.3d at 189. At a minimum, this would require proof that Mittapalli had 

actually sought the subpoenaed documents from parties in the Louisiana case 

and that those parties had failed to produce the documents despite reasonable 

diligence by Mittapalli. Mittapalli has not made this showing here. While the 

record contains some discovery requests that Mittapalli has apparently served 

in the Louisiana case, the record does not show (1) what was produced in 

response, (2) whether the production was inadequate, or (3) what steps Mittapalli 

has taken to cure the inadequacy, e.g., deficiency letters, motions to compel, and 

rulings on those motions. Until Mittapalli has “exhausted [his] efforts” to obtain 

the needed documents through party-vs.-party discovery, he “cannot even begin 

to argue that [he] has a substantial need to obtain the materials from the non-
19 

parties.” Echostar Commc’ns Corp. v. News Corp., 180 F.R.D. 391, 395 (D. Colo. 

1998). 

We acknowledge Mittapalli’s suggestion at oral argument that his expert 

may need documents from Dethmers to form opinions. Again, though, the record 

does not support this view. No expert has filed an affidavit that describes a need 

for particular documents or information within Dethmers’s exclusive control. 

Moreover, as Dethmers points out, its EZ Latch coupler is available for purchase 

in the marketplace. Like Dethmers, we suspect that a qualified engineer would 

be able to purchase an exemplar, study its design, and provide useful opinions 

as to whether Dethmers’s design was a safer, feasible alternative. While we 

understand that this would impose costs on Mittapalli, we again emphasize that 

the burdens of litigation should generally fall on the litigants, not bystanders. 

In short, Mittapalli has failed to show a need for the documents requested. 

In our view, this alone provides an adequate basis to quash Mittapalli’s subpoena 

to nonparty Dethmers. See, e.g., Moon v. SCP Pool Corp., 232 F.R.D. 633, 638 

(C.D. Cal. 2005) (“Since plaintiffs have not shown they have attempted to obtain 

these documents from defendant, the Court finds that, at this time, requiring 

nonparty KSA to produce these documents is an undue burden on nonparty 

KSA.”). 

We could end our discussion here. In the interest of thoroughness, though, 

we note that other relevant factors also weigh against enforcement. Consider, for 

example, the breadth of the requests. Leonard, 38 F.4th at 489. Mittapalli’s very 

first request would have required Dethmers to produce “any and all documents 
20 

. . . relative to . . . [t]he general scope of Dethmer/Demco’s business as it relates 

to the design, development, and manufacturing of trailer coupling devices.” 

Fairly read, this would have obligated Dethmers to produce every document that 

relates in any way to Dethmers’s trailer-coupling business. And that is just the 

first of Mittapalli’s twenty-two requests, many of which are similarly broad. In 

short, Mittapalli’s subpoena was overly broad on its face. This alone could justify 

quashing the subpoena. Wiwa, 392 F.3d at 818 (“A court may find that a 

subpoena presents an undue burden when the subpoena is facially overbroad.”). 

We next consider “the time period covered by” Mittapalli’s requests. 

Leonard, 38 F.4th at 489 (quoting Wiwa, 392 F.3d at 818). Of his twenty-two 

requests, almost all of them lack clear temporal boundaries. Only two of them 

specify a relevant time period—a decade-and-a-half-long period from “January 1, 

2006 to the present.” The temporal breadth of Mittapalli’s requests weighs 

against enforcement. 

Next we consider “the particularity with which” Mittapalli “describe[d] the 

requested documents.” Id. (quoting Wiwa, 392 F.3d at 818). While a few of 

Mittapalli’s requests are particular, many are very general. For instance, request 

#3 demands that Dethmers produce “any and all documents . . . relative to . . . 

[f]acts and circumstances surrounding the design, development, and 

manufacturing of the Demco EZ Latch coupler.” We think Dethmers would 

struggle to know just exactly what this covers and what it does not. This, too, 

weighs against enforcement. 
21 

Finally, we consider the burden imposed on Dethmers. We recall Ten 

Haken’s affidavit testimony that: 

To the extent that we can understand what is being asked of us, the 

information [required by Mittapalli’s subpoenas] would require 

substantial expense and man-hours to gather. Gathering this 

information would involve examination of many physical files and 

computer files. Dethmers’ business records are not kept in a way 

that corresponds with [the subpoenas’] categories. Gathering these 

records would adversely impact Dethmers’ business operations and 

affect Dethmers’ income by devoting man-hours to useless activity 

instead of profitable activity. 

While Ten Haken’s affidavit doesn’t specify a dollar figure, we think it 

provides enough detail to show considerable burden. Indeed, even without the 

benefit of an affidavit, experienced litigators can anticipate that a “large and 

demanding” request like Mittapalli’s would impose substantial financial 

burdens. Jordan, 921 F.3d at 189. 

For all of these reasons, we conclude that the district court should have 

quashed the subpoena for documents. For similar reasons, we also believe that 

the court should have quashed the subpoena for deposition testimony. The same 

undue-burden standards apply to both kinds of subpoenas. Jordan, 921 F.3d at 

193 (“The same undue-burden standard ‘applies to both document and 

testimonial subpoenas.’ ” (quoting Watts v. SEC, 482 F.3d 501, 508 (D.C. Cir. 

2007))). And here, the twenty-two categories described in Mittapalli’s deposition 

subpoena are identical to the twenty-two categories described in Mittapalli’s 

document subpoena. As explained, we believe that these demands are facially 

overbroad. 
22 

We note also that special requirements apply when, as here, a subpoena 

requires depositions under rule 1.707(5),5 Iowa’s counterpart to Federal Rule of 

Civil Procedure 30(b)(6). Depositions under rule 1.707(5) impose special burdens 

on the organizations deposed. See 8A Charles Alan Wright et al., Federal Practice 

and Procedure § 2103, at 455 (3d ed. 2010) (noting that “the burdens faced” by 

a corporation responding to a Rule 30(b)(6) deposition “are considerably more 

challenging than with an ordinary deposition”). The organization must designate 

persons “who consent to testify on its behalf.” Iowa R. Civ. P. 1.707(5). The 

designees must testify “to matters known or reasonably available to the 

organization.” Id. Thus, the organization must prepare the designees so that they 

can testify not merely to “matters personally known to [the] designee[s],” but 

rather “to all information reasonably available” to the organization. Fuentes v. 

Classica Cruise Operator Ltd., 32 F.4th 1311, 1321–22 (11th Cir. 2022) (first 

alteration in original) (emphasis added) (quoting Brazos River Auth. v. GE Ionics, 

Inc., 469 F.3d 416, 433 (5th Cir. 2006)); see Edwards v. Scripps Media, Inc., 

331 F.R.D. 116, 121 (E.D. Mich. 2019) (“A Rule 30(b)(6) witness is obligated to 

5Iowa Rule of Civil Procedure 1.707(5) provides:

A notice or subpoena may name as the deponent a public or private corporation 

or a partnership or association or governmental agency and describe with 

reasonable particularity the matters on which examination is requested. In that 

event, the organization so named shall designate one or more officers, directors, 

or managing agents, or other persons who consent to testify on its behalf, and 

may set forth, for each person designated, the matters on which the witness will 

testify. A subpoena shall advise a nonparty organization of its duty to make such 

a designation. The persons so designated shall testify as to matters known or 

reasonably available to the organization. This rule does not preclude taking a 

deposition by any other procedure authorized in the rules in this chapter.
23 

become educated to the extent possible about the identified topics, although 

perfection is not expected.”). 

Preparation like this can be “an onerous and burdensome task.” QBE Ins. 

Corp. v. Jorda Enters., Inc., 277 F.R.D. 676, 689 (S.D. Fla. 2012). It absorbs 

substantial resources, including employees’ time, energy, and focus. Moreover, 

if the organization “cannot identify the outer limits of the areas of inquiry” for 

the deposition, compliant designation may not be feasible. McBride v. 

Medicalodges, Inc., 250 F.R.D. 581, 584 (D. Kan. 2008). 

So, like its federal counterpart, rule 1.707(5) obligates the requesting party 

to “describe with reasonable particularity the matters on which examination is 

requested.” Iowa R. Civ. P. 1.707(5) (emphasis added). We interpret this to mean 

that requests for rule 1.707(5) testimony must be clear and specific about “what 

is called for and what is not.” Woods v. Standard Fire Ins., 589 F. Supp. 3d 675, 

684 (E.D. Ky. 2022) (quoting Alvey v. State Farm Fire & Cas. Co., No. 5:17–CV–

00023–TBR–LLK, 2018 WL 826379, at *7 (W.D. Ky. Feb. 9, 2018)); see also 

Edwards, 331 F.R.D. at 121 (“Some courts construe ‘reasonable particularity’ as 

requiring a notice of deposition under Rule 30(b)(6) to identify topics with 

‘painstaking specificity.’ Plaintiff challenges this construction, but there is no 

dispute that topics must be stated with enough specificity to allow the 

corporation to designate and prepare a representative to testify.” (quoting 

Ga.-Pac. Consumer Prod., LP. v. NCR Corp., No. 1:11–CV–483, 2015 WL 

11236844, at *1 (W.D. Mich. Feb. 23, 2015))). 
24 

Because we have concluded that both subpoenas should be quashed on 

undue-burden grounds, we need not decide whether Mittapalli’s testimonial 

requests met the reasonable-particularity test. Murphy v. Kmart Corp., 

255 F.R.D. 497, 506 (D.S.D. 2009) (noting that the party requesting the 

deposition must meet the reasonable-particularity requirement). As we 

emphasized in our discussion of the undue-burden issue, though, we think that 

many of Mittapalli’s requests were too broad and too general. If Mittapalli elects 

to issue subpoenas to Dethmers in the future, we expect that Mittapalli’s 

demands will be narrow and specific. 

Likewise, because we conclude that this case should be resolved on 

general undue-burden grounds, we need not reach Dethmers’s specific concern 

that Mittapalli’s subpoenas required disclosure of “trade secret[s] or other 

confidential research, development, or commercial information.” See

Iowa R. Civ. P. 1.1701(4)(d)(2)(1) (providing protections against disclosure of “a 

trade secret or other confidential research, development, or commercial 

information”); see also Sioux Pharm, Inc. v. Eagle Lab’ys, Inc., 865 N.W.2d 528, 

538–39 (Iowa 2015) (discussing appropriate measures for the protection of trade 

secrets). Similarly, we need not reach Dethmers’s concern that Mittapalli’s 

subpoenas required disclosure of expert opinions. See Iowa R. Civ. P. 

1.1701(4)(d)(2)(2); see also Mason v. Robinson, 340 N.W.2d 236, 237 (Iowa 1983) 

(en banc) (determining that litigants do not “have an absolute right to compel an 

unwilling expert to give an opinion on facts outside the expert’s personal 

knowledge”). As we mentioned in our undue-burden analysis, though, we 
25 

generally expect that parties in products-liability cases will retain their own 

privately-paid experts and, to the extent practicable, rely on those experts to 

fulfill their needs. This, again, is consistent with our view that—to the extent 

practicable—litigants should bear the burdens of litigation. 

Two final notes. First, as mentioned, subsection 4(d)(1)(4) provides that 

“[o]n timely motion, the issuing court must quash or modify a subpoena that . . . 

[s]ubjects a person to undue burden.” Iowa R. Civ. P. 1.1701(4)(d)(1)(4) (emphasis 

added). As a general rule, “modification of a subpoena is . . . preferred to outright 

quashing.” Linder v. Nat’l Sec. Agency, 94 F.3d 693, 698 (D.C. Cir. 1996). As 

explained, though, the record here does not show that Mittapalli cannot fulfill 

his needs through discovery in the Louisiana case, through public information 

sources, or through his own privately-retained experts. At this stage, then, the 

record does not show that Mittapalli needs nonparty Dethmers to produce 

anything. 

We also note that in his appellate brief, Mittapalli has advised this court 

that the nature and scope of the Louisiana litigation has recently changed. After 

the district court entered the orders at issue here, Mittapalli settled with U-Haul, 

who was previously the main defendant. Now, the Louisiana case is focused on 

Horizon Global, who allegedly manufactured the trailer coupler that failed. We 

think these changes are significant. U-Haul was repeatedly mentioned in the 

subpoenas, in the hearing on Dethmers’s motion to quash, and in the orders 

from which Dethmers appeals. Conversely, we do not find Horizon Global 

mentioned in Mittapalli’s subpoenas, in the hearing transcript, or in the district 
26 

court’s orders. Moreover, Mittapalli concedes that his settlement with U-Haul 

has substantially narrowed his needs for documents and information. Given 

these circumstances, we believe that it is more appropriate to simply quash the 

subpoenas before us rather than trying to reform them to fit Mittapalli’s current 

needs, which are not discernable from the record. 

Second, we note that if we had instead chosen to only modify the 

subpoenas and, therefore, to require Dethmers to comply with some of 

Mittapalli’s demands, we would have been obligated to also consider rule 

1.1701(4)(b)(2)(2). It requires that an order compelling compliance with a 

subpoena “must protect a person who is neither a party nor a party’s officer from 

significant expense resulting from compliance.” Iowa R. Civ. P. 1.1701(4)(b)(2)(2). 

But see id. r. 1.1701(4)(d)(1) (requiring the subpoenaed party to make timely 

objection). Like its federal counterpart, the words of this rule 

leave[] no room for doubt that the rule is mandatory. Thus, when 

discovery is ordered against a non-party, the only question before 

the court in considering whether to shift costs is whether the 

subpoena imposes significant expense on the non-party. If so, the 

district court must order the party seeking discovery to bear at least 

enough of the cost of compliance to render the remainder “nonsignificant.” 

Legal Voice, 738 F.3d at 1184; see Leonard, 38 F.4th at 490 n.8 (noting Rule 

45(d)(2)(B)(ii) “requires a district court to shift a nonparty’s cost of complying 

with a subpoena if those costs are significant”); Rhea v. Apache Corp., 

833 F. App’x 186, 190 (10th Cir. 2020) (“An order directing production from a 

non-party over that party’s objection ‘must protect’ that party ‘from significant 

expense resulting from compliance.’ ” (quoting Fed. R. Civ. P. 45(d)(2)(B)(ii))); see 
27 

also In re Am. Nurses Ass’n, 643 F. App’x 310, 314 (4th Cir. 2016) (per curiam) 

(“Although Fed. R. Civ. P. 45 does not explicitly define what constitutes an 

‘expense resulting from compliance,’ we conclude that attorney’s fees incurred 

by the non-party that are necessary to a discovery proceeding under Rule 45 are 

expenses that may be shifted to the discovery-seeking party.”); In re Application 

of Michael Wilson & Partners, Ltd., for Jud. Assistance Pursuant to 28 U.S.C. 1782, 

520 F. App’x 736, 739 (10th Cir. 2013) (“Although Rule 45(c)(2)(B)(ii) protects a 

nonparty subpoena respondent from ‘significant expense,’ expenses, including 

attorney’s fees, must be reasonable.”). 

Because we have elected to quash the subpoenas entirely, however, we are 

not requiring Dethmers to comply with any of Mittapalli’s demands. As a result, 

we need not (1) evaluate the costs of compliance, (2) determine whether those 

costs are “significant,” or (3) decide what portion of those costs must be shifted 

to Mittapalli so that the costs imposed upon Dethmers are rendered 

“non-significant.” Legal Voice, 738 F.3d at 1184. 

III. Conclusion. 

Mittapalli’s subpoenas are overly burdensome on their face. They should 

be quashed. We reverse and remand for entry of an order quashing the 

subpoenas. This opinion does not preclude Mittapalli from issuing different 

subpoenas to Dethmers in the future. 

REVERSED AND REMANDED. 

Waterman, J., files a concurrence, in which Mansfield, J., joins. 
28 

#21–1652, In re Subpoenas Issued to Dethmers Manufacturing 

WATERMAN, Justice (concurring). 

I join the court’s opinion in full. I write separately to comment on the lack 

of a good-faith effort by counsel to resolve this dispute without court 

intervention. The full court doesn’t discuss the issue because it wasn’t raised by 

the parties to this appeal or addressed by the district court. Fair enough. But 

this Louisiana case has consumed considerable court time in our state and will 

consume more on remand. In my view, most discovery disputes can and should 

be resolved by counsel without court intervention. Our rules of civil procedure 

generally require lawyers to make a good-faith personal effort to resolve or 

narrow discovery disputes before filing a motion with the court. That didn’t 

happen in this case. 

I agree that the original subpoena was overbroad and unduly burdensome. 

Mittapalli’s counsel, not surprisingly, declined to “bid against himself” and 

narrow the subpoena when Dethmers’s attorney refused to negotiate at all. 

Dethmers’s attorney, at our podium, gave his reason: U-Haul, a key customer 

and defendant in the Louisiana case, would look askance at any “cooperation” 

with Mittapalli’s lawyer. How did that go for Dethmers? The district court ordered 

Dethmers to comply with the original subpoena in full. Dethmers’s recalcitrance 

led to this appeal at its expense and a Pyrrhic victory in our court with Mittapalli 

free after remand to seek a narrower subpoena. 

Perhaps if Dethmers’s attorney had picked up the phone, all of this time 

and trouble could have been avoided by a discussion with Mittapalli’s lawyer. 
29 

Perhaps discussions would have been fruitless. We don’t know because 

Dethmers’s lawyer didn’t try. One expects that at least their discussions would 

have further narrowed the dispute before taking up Iowa court time. In my view, 

counsel shouldn’t stonewall and punt the full dispute to the court for business 

reasons when our rules require good-faith negotiations. 

As the lead opinion recognizes, this subpoena in aid of the Louisiana action 

is governed by Iowa Rule of Civil Procedure 1.1702, entitled “Uniform interstate 

depositions and discovery.” Motions to quash filed by the responding party 

(Dethmers) “must comply with the rules or statutes of this state” and “[i]n 

addition, the provisions of [Iowa Rule of Civil Procedure] 1.517 apply to motions 

brought under this rule.” Iowa R. Civ. P. 1.1702(6). Rule 1.517 in turn provides: 

Motions relating to discovery. No motion relating to depositions, 

discovery, or discovery sanctions may be filed with the clerk or 

considered by the court unless the motion alleges that the movant 

has in good faith personally spoken with or attempted to speak with 

other affected parties in an effort to resolve the dispute without court 

action. The certification must identify the date and time of any 

conference or attempts to confer. 

Id. r. 1.517(5); see also Carter v. Carter, 957 N.W.2d 623, 634–35 (Iowa 2021) 

(noting obligation of plaintiffs’ counsel to discuss scope of subpoena with 

nonparty recipient); Hearn v. Iowa Dist. Ct., No. 10–1383, 2011 WL 3480985, 

at *7 (Iowa Ct. App. Aug. 10, 2011) (noting responding party’s failure to comply 

with the good-faith requirement and stating that “[t]he expense in time and 

resources devoted to ongoing discovery disputes involving court intervention by 

all parties to this litigation is unacceptable”). 
30 

The district court could have simply denied Dethmers’s motion to quash 

based on its failure to comply with our rules requiring that Dethmers certify it 

made a good-faith effort to speak with Mittapalli’s counsel to “resolve the dispute 

without court action.” Iowa Rs. Civ. P. 1.517(5), 1.1702(6). That might have 

prompted productive discussions. 

Some federal courts have held that the “meet and confer” requirement does 

not apply to a nonparty’s motion to quash a subpoena. See, e.g., Housemaster 

SPV LLC v. Burke, No. 21–13411 (MAS), 2022 WL 17904254, at *7 (D.N.J. 

Dec. 23, 2022) (holding that Federal Rule of Civil Procedure 45, regarding 

subpoenas, governed rather than Local Rule 37.1, which requires good-faith 

effort, and stating that “courts have dispensed with requiring a party and 

non-party to meet and confer prior to filing a motion under Rule 45” and citing 

cases). Federal cases aren’t binding on our interpretation of the Iowa rules. In 

any event, other federal cases extol the value of the good-faith effort requirement: 

The primary purpose of requiring a meet and confer before 

filing a motion is not to lessen the Court’s workload—although that 

is often a pleasant result. Genuine, good-faith efforts by the parties 

to resolve their disputes before seeking Court intervention often 

result in greater control over the outcome, acceptable compromise, 

and/or appreciably narrowed issues, thereby saving the litigants 

unnecessary expense. Thus, it is the policy of this Court—and a 

requirement under the Local Rules—to have the parties meet and 

discuss discovery disputes before seeking Court intervention. 

Sheehan Pipe Line Constr. Co. v. Liberty Mut. Ins., No. 04–CV–891–JOE–PJC, 

2005 WL 8174999, at *2 (N.D. Okla. Nov. 9, 2005); see also FTC v. Mytel Int’l 

Inc., No. CV 87–7259 GHK (SSx), 2015 WL 13938260, at *2 (C.D. Cal. Oct. 19, 
31 

2015) (denying defendants’ motion to quash a subpoena issued to nonparty 

financial institutions because parties failed to meet and confer in good faith).

Regardless, the better practice is for lawyers to try to resolve discovery 

disputes over nonparty subpoenas before going into court on a motion to quash 

the subpoena (or to enforce it). We expect that of Iowa lawyers. 

Mansfield, J., joins this concurrence.
