OXLEY, Justice.

The University of Iowa Stead Family Children’s Hospital overlooking 

Kinnick Stadium is a proud landmark in Iowa City known nationwide for the 

“Kinnick wave”—a tradition since 2017 where, at the end of the first quarter of 

every home Iowa Hawkeye football game, the nearly 70,000 fans, players, 

coaches, referees, and opponents inside Kinnick Stadium turn to wave at the 

patients and families in the top floors of the Children’s Hospital.1 Although its 

landmark status is now settled, construction of the Children’s Hospital did not 

go smoothly. This case involves one of the construction disputes—at least at the 

periphery—between the University of Iowa and Modern Piping, Inc., the 

mechanical contractor for the project.

The case started with Modern Piping’s attempt to settle some of the parties’ 

construction disputes. Modern Piping wanted to arbitrate some delay disputes; 

the University did not. The University obtained an ex parte temporary injunction 

that prohibited the American Arbitration Association (AAA) from arbitrating specific disputes presented by Modern Piping. Modern Piping intervened and got the 

temporary injunction dissolved. The University appealed, but it was unsuccessful. Meanwhile, the parties arbitrated the original disputes, and the University 

paid Modern Piping over $16 million pursuant to the arbitration award. 

But this appeal is not about arbitration. It is about damages available to 

a party who, like Modern Piping, is enjoined by a court order that is later 

determined to have been wrongfully entered. After the University lost its appeal 

about the validity of the injunction, Modern Piping attempted to recover not only 

the fees and costs it incurred in dissolving the injunction, but also the restitution

it claimed was necessary to avoid unjustly enriching the University for its 

actions. What started as a request for fees and costs, for which Modern Piping 

was eventually awarded just over $21,000, turned into a jury verdict also 

awarding Modern Piping over $12.7 million of the University’s profits in operating 

the Children’s Hospital during its first eight months. 

As explained below, the restitution awarded here is not a proper remedy 

for a claim for wrongful injunction and cannot stand. The judgment is affirmed 

in part and reversed in part. The $21,784.50 award to Modern Piping for fees 

and costs is affirmed, and the $12,784,177.00 award for restitution is reversed.

I.

Modern Piping is a Cedar Rapids construction contractor that entered separate contracts in August and September 2013, respectively, to serve as the mechanical contractor for two large projects on the University campus in Iowa City. 

The first contract involved the construction of the fourteen-story Children’s Hospital adjacent to the University of Iowa Hospitals and Clinics that overlooks Kinnick Stadium. Construction of the Children’s Hospital was an almost $330 million project, and Modern Piping’s mechanical contract accounted for just over 

$28 million. The second contract involved replacing the 1,800-seat Hancher Auditorium following the 2008 flood. Replacement of Hancher was an approximately $176 million project, and Modern Piping’s mechanical contract was over 

$11 million.

Both contracts included “general conditions of the contract” with identical 

arbitration provisions. Under the contract, arbitration of disputes became mandatory once a party referred the dispute to the design professional.

2 On February 

2The “design professional” is the person generally tasked with advising and consulting 

with the owner of the project. He has the authority to interpret the contract documents and make 

recommendations when there is a dispute between the owner and contractor.

27, 2015, Modern Piping filed a claim with the AAA related to what turned into 

approximately $1.6 million worth of claimed delays in the Hancher project. The 

University challenged arbitrability, Modern Piping brought a claim in district 

court to enforce arbitration, and the court ordered the parties to arbitrate on 

February 16, 2016. 

On March 23, Modern Piping filed an amended claim with the AAA seeking 

to add claims related to the Children’s Hospital to the pending Hancher arbitration proceeding. The Children’s Hospital disputes totaled over $8 million and 

similarly related to claimed delays and schedule compression, congestion, and 

out-of-sequence construction. The University refused to consent to arbitrating 

the Children’s Hospital disputes as part of the pending Hancher arbitration.

On April 1, the University filed an ex parte petition in district court against 

the AAA. The only relief it sought was a temporary and permanent injunction 

enjoining the AAA from adding the Children’s Hospital claims to the Hancher 

arbitration proceedings. To support its request for an immediate temporary injunction, the University asserted that being forced to arbitrate a dispute over an 

unrelated project would require it “to direct resources from the completion of the 

time sensitive Children’s Hospital Project to arbitrate a matter not properly before the AAA.” The petition named the AAA as a defendant but not Modern Piping. 

The same day, the district court issued a temporary injunction pursuant to Iowa 

Rule of Civil Procedure 1.1507, which allows entry of an injunction without prior 

notice to the enjoined party. The injunction ordered that the AAA “is temporarily 

enjoined from presenting the dispute over the Children’s Hospital Project to arbitration until further action from the Court.” The AAA answered the petition on 

May 20 but did not otherwise seek to lift the injunction.

Seven months later, Modern Piping filed a motion to intervene and a motion to dissolve the temporary injunction on November 2. Modern Piping was 
5 4/25/2024 3:22:12 PM

allowed to intervene, and on January 10, 2017, the district court dissolved the 

temporary injunction on the basis that the AAA—the only named defendant—

was protected by arbitral immunity as argued by Modern Piping. 

In June 2016—after the temporary injunction was granted in April and 

before it was lifted the following January—the University sought to use and occupy a portion of the Children’s Hospital, although construction was not complete. Partial occupancy was contemplated by section 9.7.1 of the general conditions, which provided that “[t]he Owner may occupy or use any completed or 

partially completed portion of the Work at any stage when such portion is designated by separate agreement with the Contractor.” The contract required the 

parties to assign responsibilities between them for such things as maintenance, 

utilities, damage to the work, and insurance, and it provided that the contractor 

could not unreasonably withhold consent. Modern Piping attempted to reach an 

agreement concerning partial occupancy with the University, but the University 

refused to enter into the separate agreement required by the general conditions. 

The University nonetheless partially occupied certain floors of the Children’s 

Hospital that were substantially complete before the entire construction project 

was completed. The University began preparing and furnishing the facility with 

needed technology, equipment, and other supplies starting in June 2016, which 

in turn allowed the University to start accepting patients in the new facility in 

February 2017, eight months earlier than it otherwise would have absent the 

early use and occupancy. Construction of the Children’s Hospital was completed 

in May 2017.

Back at the AAA, an arbitration panel had been appointed and confirmed 

to arbitrate Modern Piping’s Hancher claims on October 27, 2016. The 

arbitration panel recognized that Modern Piping’s claims related to the Children’s 

Hospital were on hold until the panel received notice on February 1, 2017, that 
6 4/25/2024 3:22:12 PM

the temporary injunction had been dissolved. The panel was then able to proceed 

with respect to both the Hancher and the Children’s Hospital disputes presented 

by Modern Piping in its amended statement of claims. By this time, the 

University had been occupying parts of the Children’s Hospital for several 

months without entering into a separate agreement with Modern Piping, but 

Modern Piping did not submit that breach of contract claim to the Design 

Professional or otherwise attempt to arbitrate with respect to the University’s 

partial occupancy. The panel heard testimony from fifteen witnesses over nine 

days in September 2017 about the delays related to both projects and was 

provided with approximately one thousand exhibits. On March 5, 2018, the 

arbitration panel issued a final award to Modern Piping in the amount of 

$21,493,129.91, plus interest. Of that award, $16,334,135.40 related to claims 

concerning the Children’s Hospital, stemming primarily from significant labor 

inefficiencies outside of Modern Piping’s control and an “inordinate number of 

[design] changes . . . made throughout the project.” In addition, the award 

included prejudgment interest of $930,000, attorney fees and expenses over 

$416,000, and nearly $500,000 in costs and expenses of the arbitration 

proceeding. The arbitration award was confirmed by a district court and affirmed 

on appeal. See Mod. Piping, Inc. v. Bd. of Regents ex rel. Univ. of Iowa, 2019 WL 

1494649, at *2 (Iowa Ct. App. Apr. 3, 2019). Modern Piping filed a satisfaction of 

judgment reflecting full payment of the award on June 13, 2019. 

In the district court case involving the University’s request for an injunction against the AAA, the district court dissolved the temporary injunction on 

January 10, 2017, on the basis of arbitral immunity. On March 17, the AAA 

sought summary judgment to dismiss the University’s petition for a permanent 

injunction on the same basis. The district court granted summary judgment to 

the AAA on April 27, dismissing all of the University’s claims. On May 8, the 
7 4/25/2024 3:22:12 PM

University filed postjudgment motions, and Modern Piping filed a motion for attorney fees and costs incurred in dissolving the temporary injunction. The district court denied the postjudgment motions on May 30 and set Modern Piping’s 

motion for fees and costs for hearing on July 19. The University appealed the 

district court’s summary judgment order on June 15, which the court of appeals 

affirmed on January 9, 2019. Univ. of Iowa v. Am. Arb. Ass’n, 2019 WL 141003, 

at *2 (Iowa Ct. App. Jan. 9, 2019). Modern Piping’s May 8, 2017 motion for fees 

and costs remained pending during the appeal. The University had requested a 

continuance based on a conflict with the scheduled July 19 hearing, and the 

district court granted the continuance without resetting a hearing. Neither party 

asked the court to hear the motion during the pendency of the appeal.

After procedendo issued following the appeal, the district court entered an 

order on March 11, 2019, noting the outstanding motion for fees and costs and 

inviting the parties to identify any remaining issues. Modern Piping filed a motion 

for leave to add a counterclaim, noting its motion for fees and costs was still 

pending and asserting that its “claim for wrongful injunction has now ripened.” 

Modern Piping asserted it was entitled to recover for the harm it suffered while 

the temporary injunction was in place, “including without limitation delays to 

the arbitration, attorneys’ fees and related costs to obtaining the dissolution of 

[the University’s] wrongful injunction, and other damages.” It also made a 

demand for a jury trial.

The proposed counterclaim alleged that Modern Piping had filed a demand 

for arbitration with the AAA on March 23, 2016, for claims involving the 

Children’s Hospital project that it had referred to the Design Professional, and 

the University refused to participate in arbitration. It alleged that the district 

court temporarily enjoined the AAA from arbitrating those claims with the 

pending Hancher arbitration. It also alleged that after the temporary injunction 
8 4/25/2024 3:22:12 PM

was dissolved on January 10, 2017, the parties proceeded with the arbitration 

on all claims that had been referred to the Design Professional, resulting in an 

award to Modern Piping of $21,493,129.91 plus interest. It then alleged that 

“Modern Piping was harmed by the wrongful ex parte injunction [the University] 

obtained for the time period between April 1, 2016, through January 10, 2017, 

resulting in damages, delays to the arbitration, attorneys’ fees and related costs 

to obtaining the dissolution of [the University’s] wrongful injunction, and other 

damages.” Modern Piping sought damages “including without limitation 

compensatory, consequential, and restitutionary . . . damages[,] attorneys’ fees 

and expenses that it incurred . . . , interest, court costs, and any other relief that 

is just and appropriate.”

Over the University’s resistance, the district court allowed Modern Piping 

to add the counterclaim. The district court recognized that a ruling on Modern 

Piping’s motion for fees and costs was still outstanding and that some 

jurisdictions allow a claim for wrongful injunction to be asserted within the 

injunction suit itself. The district court acknowledged the University’s argument 

that Modern Piping’s claim was a tort claim analogous to a claim for abuse of 

process precluded by immunity under Iowa Code § 669.14(4) (2019), 

characterizing Modern Piping’s counterclaim as one “for damages pertaining to 

delay in arbitration based on a wrongful injunction consistent with an abuse of 

process theory.” Nonetheless, it concluded “that Modern Piping should be 

allowed to bring this claim, to the extent it is an actual counterclaim, in order to 

resolve the costs, attorney fees and damages resulting directly from the 

injunction sought and then dissolved by the [University] in this case.”

The University subsequently filed a motion for partial summary judgment

with respect to the appropriate measure of damages for Modern Piping’s wrongful 

injunction counterclaim. The University sought a ruling that Modern Piping’s 
9 4/25/2024 3:22:12 PM

requests for consequential and restitutionary damages were beyond the scope of 

damages allowed in a claim for wrongful injunction. In its resistance to summary 

judgment, Modern Piping argued that as a legal matter restitution is a proper 

remedy for a wrongful injunction. And it argued that as a factual matter the 

University’s temporary injunction prevented Modern Piping not only from 

arbitrating the Children’s Hospital disputes it had submitted for arbitration, but 

also from litigating any of its contractual rights related to the Children’s Hospital 

during the pendency of the temporary injunction for risk of waiving its ability to 

arbitrate such claims, causing Modern Piping to suffer substantial damages. The 

substantial damages identified by Modern Piping included those stemming from 

its alleged inability to enforce other contractual rights. Specifically, Modern 

Piping asserted that the University took advantage of the temporary injunction 

by breaching the partial use and occupancy provision of the general conditions 

of the parties’ contract to open the Children’s Hospital before construction was 

complete without entering the separate agreement required by the general 

conditions. Modern Piping argued that the University had been unjustly enriched 

and that Modern Piping was entitled to restitution in the form of disgorgement 

of the University’s profits earned from the early occupancy. 

The district court denied the University’s motion for summary judgment, 

concluding that the jury should be allowed “to consider Modern Piping’s allegations that imposition of the injunction delayed Modern Piping’s ability to enforce 

its contractual rights, as well as its ability to litigate its disputes with the state.” 

The University also consistently challenged Modern Piping’s wrongful 

injunction claim as the functional equivalent of a claim for abuse of process, 

from which the state is immune under Iowa Code § 669.14(4). In rejecting the 

University’s postdiscovery motion to dismiss on the basis of sovereign immunity, 

the district court concluded that a wrongful injunction claim is not functionally 
10 4/25/2024 3:22:12 PM

equivalent to abuse of process because the claims have different intent elements: 

“[T]here is no requisite mental state to be considered in a wrongful injunction 

claim, whereas an abuse of process claim focuses on a defendant’s purpose in 

bringing an action.” 

Modern Piping’s claim for wrongful injunction was tried to a jury in 

October 2022. During the three-day trial, Modern Piping’s evidence focused 

almost exclusively on the University’s partial occupancy of the Children’s 

Hospital. Its senior executive project manager and minority owner, Mike Shive, 

testified about the additional work required of Modern Piping from the 

University’s early occupation of the Children’s Hospital. To that end, much of 

Shive’s testimony focused on the University’s bad faith in refusing to negotiate a 

partial occupancy agreement with Modern Piping. Shive testified that his 

University counterparts, including electrical and mechanical project manager 

Jason Miller, refused to even discuss the partial occupancy matter with him. 

Modern Piping introduced emails from University officials identifying the 

temporary injunction as “good news,” that “[i]t would take a hearing in Johnson 

County Court to change this order,” and “it is imperative that Heery, the Design 

Professional, not accept nor analyze any claims submitted by Modern Piping.”

Another email discussed Miller’s view that “Modern [Piping] . . . should be put 

out of business with the way they handled this project.” On cross-examination,

Shive admitted that the temporary injunction itself did not prevent the parties 

from entering into a partial occupancy agreement.

Modern Piping also presented testimony from a legal expert who opined 

about the injunction’s wrongfulness and the harm caused to Modern Piping as 

a result. Much of the legal expert’s testimony concerned the University’s 

motivation for seeking the injunction, which he opined was the University’s

desire to move into the unfinished Children’s Hospital without having to first 
11 4/25/2024 3:22:12 PM

arbitrate a partial occupancy agreement. This improper purpose for obtaining 

the temporary injunction laid the foundation for his professional opinions that 

the temporary injunction was wrongful, the injunctive order empowered the 

University to partially occupy the unfinished Children’s Hospital, and the early 

occupancy prevented Modern Piping from arbitrating the partial occupancy 

dispute like it normally would have done, causing lost contract damages to 

Modern Piping and benefiting the University. Similar to Shive’s testimony, the 

legal expert testified on cross-examination that the temporary injunction did not 

preclude the parties from entering an agreement on the partial occupancy issue 

and that Modern Piping could have submitted the early occupation issue to 

arbitration after the temporary injunction was dissolved in January 2017, but it 

was not required to do so. 

Modern Piping’s economic expert testified that the University received an 

additional profit of $12,784,177 because it was able to accept patients eight 

months earlier than if it had not partially occupied the Children’s Hospital. He 

also testified that had the parties negotiated an agreement for partial occupancy 

pursuant to the general conditions, then Modern Piping would have submitted a 

bid for $2,502,068, which he characterized as the additional risk associated with 

completing its work while the University was partially occupying the Children’s 

Hospital. 

Prior to and during trial, the University raised numerous objections to evidence concerning its improper purpose in obtaining the injunction, which it argued was not relevant to establishing the injunction’s wrongfulness and effectively allowed Modern Piping to try its wrongful injunction claim as an abuse of 

process claim against the state. The district court rejected the University’s arguments based on its understanding that “the purpose, if it’s improper, of the injunction is relevant to that finding of wrongfulness.” 
12 4/25/2024 3:22:12 PM

Also over the University’s objection, the district court instructed the jury 

on Modern Piping’s wrongful injunction claim using an unjust enrichment theory 

premised on providing restitution to Modern Piping based on the benefit it conferred on the University from the wrongful injunction to avoid unjustly enriching 

the University. The jury found for Modern Piping, concluding that the University 

was “unjustly enriched due to the wrongful injunction” in the amount of 

$12,784,177 and that “the reasonable and necessary costs, expenses, and attorney’s fees expended by Modern Piping to dissolve the wrongful injunction” totaled 

$21,784.50.

II.

The University appealed, and we retained the appeal. The University raises 

a number of issues on appeal, but we believe only two issues need to be addressed in resolving the appeal.

A.

Because a district court’s actions beyond its jurisdiction are void, see 

Wederath v. Brant, 287 N.W.2d 591, 595 (Iowa 1980) (en banc) (“The effect of 

action taken by a court without jurisdiction of the subject matter is that the 

action is void.”), we first address the University’s jurisdictional argument. The 

University challenges the district court’s jurisdiction to proceed with Modern 

Piping’s wrongful injunction counterclaim following the court of appeals opinion 

affirming dismissal of its claims in the underlying case. As a general matter, a 

district court lacks authority to decide new issues raised following affirmance of 

a final order. See Franzen v. Deere & Co., 409 N.W.2d 672, 675 (Iowa 1987) (en 

banc) (holding that defendant’s “application to impose rule 80(a) sanctions, filed 

. . . after we affirmed the final judgment of the district court . . . , was filed too 

late to give the district court authority to consider it”). But Modern Piping’s 

motion for fees and costs was filed before the appeal was taken, and the district 
13 4/25/2024 3:22:12 PM

court allowed Modern Piping to add the counterclaim under the theory that it 

was seeking ancillary relief, essentially the same relief Modern Piping had 

requested in the pending motion for fees and costs. Motions for fees and costs 

are ancillary, and a district court’s authority to rule on such motions is an 

exception to the tenet that a notice of appeal divests the district court of 

jurisdiction over the case. See State v. Mallett, 677 N.W.2d 775, 776–77 (Iowa 

2004) (“Generally, an appeal divests a district court of jurisdiction . . . . However, 

a district court maintains jurisdiction over disputes between the parties that are 

merely collateral to the issues on appeal.”).

Modern Piping’s motion for costs and fees had been continued and was 

still pending when the case returned to the district court following the appeal, 

and that motion’s continuance supported the district court’s conclusion that 

Modern Piping’s postappeal pleading merely built on the pending motion. As the 

district court recognized, courts vary on treating wrongful injunction damages 

as ancillary to the underlying case or as a separate cause of action. See, e.g., 42 

Am. Jur. 2d Injunctions § 317, at 925–26 (2020) (discussing cases). While Modern 

Piping’s claim for what started out as a request for ancillary relief morphed over 

time, the district court was not without jurisdiction over the claim. 

B.

This appeal turns on the scope of the damages an enjoined party is allowed 

to recover when it turns out that the injunction should not have been issued. In 

addition to the attorney fees and costs incurred in obtaining dissolution of the 

temporary injunction, Modern Piping also claimed that it was entitled to restitution from the University for the benefit the University received when it wrongfully 

obtained the temporary injunction. Modern Piping’s logic goes like this: Restitution is an appropriate remedy for a wrongful injunction; restitution is a form of 
14 4/25/2024 3:22:12 PM

damages for unjust enrichment; and unjust enrichment allows for the disgorgement of the enriched party’s profits. The University argues on appeal (as it did 

throughout the district court proceedings) that the type of unjust enrichment

Modern Piping sought and obtained is not available for the wrongful injunction 

at issue in this case.

The law has long been “settled in this state that, when an injunction is the 

only relief sought and the temporary writ issued therein is dissolved on final 

hearing, recovery by the defendant may be had for the reasonable and necessary 

costs, expenses, and attorney fees expended in procuring such dissolution.” 

Chrisman v. Schmickle, 230 N.W. 550, 551 (Iowa 1930); see also Burnett v. N. M. 

Stark & Co., 136 N.W. 670 (Iowa 1912) (“It is well settled that where an injunction 

is the sole relief sought, and a temporary writ is executed and afterwards 

dissolved, then the defendant in such injunction suit is entitled to recover upon 

the injunction bond his necessary costs and expenses in obtaining such 

dissolution including attorney fees.”); Weierhauser v. Cole, 109 N.W. 301, 302 

(Iowa 1906) (“Under the circumstances, where injunction is the sole relief sought, 

we have often held that its dissolution, either by interlocutory order or upon the 

final hearing, entitles the party enjoined to recover his attorney’s fees in resisting 

the writ.”). The parties do not dispute that the attorney fees and costs Modern 

Piping incurred in successfully getting the temporary injunction dissolved are 

proper damages for the wrongful injunction. Indeed, the University did not 

appeal from the $21,784.50 verdict awarded by the jury for those costs and fees.

The issue is whether Modern Piping is entitled to additional damages, which 

requires us to consider what types of damages are available for a wrongful 

injunction beyond the costs and fees incurred in getting the injunction dissolved.

Courts have generally recognized two distinct causes of action for a 

wrongful injunction: “one upon bond ordinarily filed to obtain a temporary 
15 4/25/2024 3:22:12 PM

restraining order or injunction, and the other for malicious prosecution.” 43A 

C.J.S. Injunctions § 498, at 544 (2014) (“[T]he two actions differ in the kind of 

wrong that must be shown to establish liability and in the amount of recovery.”). 

Regarding the first type of action, the general rule requires that the injunction 

was either wrongful in its inception or that it continued owing to some wrong on 

the part of the plaintiff in order to recover damages. See id. § 502, at 547. 

Although courts retain equitable discretion in determining the amount, only 

those damages actually sustained because of the injunction should be allowed. 

See id. § 515, at 561–62. In contrast, punitive or other excess damages based on 

a wrongful injunction are limited to actions for malicious prosecution or abuse 

of process, both of which require additional proof of an enjoining party’s

malicious intent or improper purpose in obtaining the temporary injunction. See 

id. § 515, at 562; see also Wilson v. Hayes, 464 N.W.2d 250, 260–61, 266 (Iowa 

1990) (en banc) (involving claims for malicious prosecution and abuse of process

and discussing both as a cause of action). Our caselaw addressing wrongful 

injunction claims is consistent with these general principles of law. 

In addition to costs and fees for obtaining the dissolution of a wrongful

injunction, we have recognized that “damages that were the natural and 

proximate result of the wrongful injunctions” could be recovered in a claim 

against an injunction bond. City of Corning v. Iowa–Neb. Light & Power Co., 282 

N.W. 791, 794 (Iowa 1938). In City of Corning v. Iowa–Nebraska Light & Power 

Co., the defendant had previously obtained a temporary injunction to prevent 

the City of Corning from constructing a competing municipal light and power 

plant. Id. at 792. The injunction was soon dissolved, and the city successfully 

defended Iowa–Nebraska’s challenge to the dissolution on appeal. Id. at 792–93.

However, the temporary injunction and bonded appeal stays prevented the city 

from moving forward with its construction efforts for nearly a year. Id. The city 
16 4/25/2024 3:22:12 PM

sued on the bonds, and Iowa–Nebraska claimed the city’s damages should be 

limited to those incurred only while the injunction and appeal stay were in place. 

Id. at 794. Our court held that the city “was entitled to compensation for damages 

that were the natural and proximate result of the wrongful injunctions and was 

not necessarily limited to a recovery of damages while the injunctions were in 

force if the damages flowing directly from the injunctions continued for a period 

of time beyond the date of their dissolution.” Id. We adopted “[t]he measure of 

damages in a case of this kind” from a leading treatise: “In determining the 

amount of damages to be allowed upon the dissolution of an injunction 

restraining one from exercising acts of ownership over his real property, . . . the 

defendant [is] entitled to such damages as are the necessary and proximate 

result of such deprivation.” Id. (emphasis added and omitted) (quoting 2 

James L. High, A Treatise on the Law of Injunctions § 1673 (4th ed. 1905)

[hereinafter High, Injunctions]). Where the injunctions directly precluded the city 

from building its power plant, the profits it would have earned from the power 

plant were “the necessary and proximate result of such deprivation.” Id.

(emphasis omitted) (quoting High, Injunctions § 1673).

The recovery of damages when a party wrongfully obtains an injunction is

analogous to the recovery of money paid or property transferred in compliance 

with a judgment that is reversed on appeal. See Schwennen v. Abell, 471 N.W.2d 

880, 884 (Iowa 1991) (“adopt[ing] the Restatement rule for voluntary payment 

cases involving reversed judgments” where a defendant paid a judgment to avoid 

accruing additional interest pending appeal). In that context, “[a] person who has 

conferred a benefit upon another in compliance with a judgment, or whose property has been taken thereunder, is entitled to restitution if the judgment is reversed or set aside . . . .” Id. at 883 (quoting Restatement (First) of Restitution:

Quasi Conts. & Constructive Trs. § 74, at 302–03 (Am. L. Inst. 1937)).
17 4/25/2024 3:22:12 PM

Modern Piping relies on the related provision from the updated 

Restatement (Third) of Restitution and Unjust Enrichment to argue it is entitled 

to restitution because the injunction was reversed. Section 18 of Restatement 

(Third) provides: “A transfer or taking of property, in compliance with or 

otherwise in consequence of a judgment that is subsequently reversed or 

avoided, gives the disadvantaged party a claim in restitution as necessary to 

avoid unjust enrichment.” 1 Restatement (Third) of Restitution & Unjust 

Enrichment § 18, at 244 (Am. L. Inst. 2011) [hereinafter Restatement (Third)].

From there, Modern Piping argues that it was entitled to seek disgorgement of 

the University’s profits by quoting from State ex rel. Palmer v. Unisys Corp., where 

we said: “Restitution measures the remedy by the gain obtained by the defendant

. . . and seeks disgorgement of that gain.” 637 N.W.2d 142, 153 (Iowa 2001). But 

stringing together quotes from cases involving restitution in different contexts

does not support Modern Piping’s position.

Restitution takes many forms. See, e.g., Unisys, 637 N.W.2d at 156 (“Subrogation, like contribution and indemnity, is a separate form of restitution.”). As 

stated in the Restatement (Third) sections that Modern Piping relies on: “The 

usual consequence of a liability in restitution is that the defendant must restore 

the benefit in question or its traceable product, or else pay money in the amount 

necessary to eliminate unjust enrichment.” Restatement (Third) § 1 cmt. a, at 3. 

“Conversely, there are cases in which the remedy for unjust enrichment gives 

the plaintiff something—typically, the defendant’s wrongful gain—that the plaintiff did not previously possess.” Id. § 1 cmt. a, at 3–4. In acknowledging that 

restitution is essentially the law of unjust enrichment, the Restatement (Third)

notes this is merely a “term of art,” and the substantive portion of restitutionary 

law “is concerned with identifying those forms of enrichment that the law treats 

as ‘unjust’ for purposes of imposing liability.” Id. § 1 cmt. b, at 4.

But “[t]he concept of unjust enrichment is not a judicial remedy to correct 

perceived injustices, unfairness, or inequities in a broad sense. Rather, the doctrine involves a ‘narrower set of circumstances giving rise to what might more 

appropriately be called unjustified enrichment.’ ” Livingood v. City of Des Moines, 

991 N.W.2d 733, 749 (Iowa 2023) (quoting Restatement (Third) § 1 cmt. b, at 4).

Both parties rely on Unisys, where we expounded on the doctrine of unjust enrichment “as a basis for restitution.” 637 N.W.2d at 154. While we “recognize[d 

that] unjust enrichment is a broad principle with few limitations,” id. at 155, we 

also said it was critical to understand “the true nature of the claim” underlying 

a claim for unjust enrichment, id. at 156. 

In Unisys, the claim was “actually one for equitable subrogation.” Id. at 

156. The state had contracted with Unisys to calculate the capitation rate the 

state used to pay health maintenance organizations (HMOs), including Heritage, 

to provide services under the Medicaid program. Id. at 147–48. Unisys made a 

mistake in its calculations that resulted in overpayments to the HMOs to the 

tune of $15 million in 1994 and $17.5 million in 1995. Id. at 148. The state sued 

Unisys for breach of contract, and Unisys brought a third-party claim for unjust 

enrichment against Heritage (and other HMOs) on the basis that Heritage should 

not be allowed to retain the overpayments—even though the state did not seek

recoupment from Heritage. Id. at 147, 149. In considering Unisys’s claim for unjust enrichment, we considered whether restitution was equitable by applying 

rules of subrogation—when one party is “compelled to pay a debt that ought to 

have been paid by another.” Id. at 156 (quoting Am. Sur. Co. of N.Y. v. Bethlehem 

Nat’l Bank of Bethlehem, 314 U.S. 314, 317 (1941)). In that context, we concluded Unisys should be allowed to pursue a claim for unjust enrichment against 

Heritage to the extent Unisys made payment to the state on its breach of contract 
19 4/25/2024 3:22:12 PM

claim and that payment would satisfy Heritage’s obligation to pay restitution to 

the state in the amount Heritage had been overpaid. Id. at 156–57.

We believe Modern Piping led the district court astray when it convinced 

the court that its claim for wrongful injunction entitled it to recover restitution 

in the form of a broad-reaching unjust enrichment claim, and restitution should 

be measured as the disgorgement of the benefit provided to the University. As in 

Unisys, it is critical that we consider the “true nature of the claim,” id. at 156,

that Modern Piping is making against the University. 

The type of restitution addressed in wrongful injunction claims, like the 

restitution available when a judgment is reversed on appeal, is limited to restoring the enjoined party to that which it lost as a direct result of the injunction. In 

the context of a reversed judgment, the Restatement (Third) recognizes restitution as a proper remedy to the extent of “[a] transfer or taking of property, in 

compliance with or otherwise in consequence of a judgment that is subsequently 

reversed or avoided.” Restatement (Third) § 18, at 244. Thus, when the defendant 

in Schwennen v. Abell paid a money judgment to avoid accruing additional interest, he was entitled to have the money he had paid restored to him when the 

judgment was reversed on appeal—a manner of restitution. See 471 N.W.2d at 

883–84. In Arkadelphia Milling Co. v. St. Louis Southwestern Ry., the United 

States Supreme Court similarly explained that a party “is entitled, in the event 

of a reversal, to be restored by his adversary to that which he has lost thereby.” 

249 U.S. 134, 145–46 (1919). So when rail carriers were allowed to charge excess 

rates during the time that an injunction precluded the Railroad Commission of 

Arkansas from enforcing its commission rates, requiring the carriers to repay the 

excess charges was “a typical case for the application of the principle of restitution.” Id. In this context, restitution restores the parties to the status quo that 

existed prior to entry of the injunction.

Modern Piping argues that—the language of the Restatement (Third)

notwithstanding—disgorging the benefit provided to the enjoining party is also a 

proper remedy for a wrongful injunction. There are instances where courts 

recognize this type of restitutionary remedy for a wrongful injunction, but those 

are tightly circumscribed. One instance is when the enjoining party obtains a 

benefit by competing with the enjoined party. For example, when “a preliminary 

injunction [is] issued to protect a patent that is eventually declared invalid, [the 

injunction] provid[es] the plaintiff with an unwarranted monopoly status during 

the litigation.” Ofer Grosskopf & Barak Medina, Remedies for Wrongfully-Issued 

Preliminary Injunctions: The Case for Disgorgement of Profits, 32 Seattle U. L. Rev.

903, 912 (2009) [hereinafter Grosskopf & Medina]; see also Fleer Corp. v. Topps 

Chewing Gum, Inc., 539 A.2d 1060, 1063 (Del. 1988) (“Because of the injunction 

issued by the District Court, Fleer was able to legally appropriate Topps’ property 

rights and market baseball trading cards, an action which would have clearly 

infringed on Topps’ exclusive rights except for the District Court’s order.”).

Modern Piping’s attempt to reach the University’s profits from operating the 

Children’s Hospital turns this theory on its head. Under no set of circumstances 

would a mechanical contractor be entitled to the profits of the business 

occupying the building it is constructing. 

Another instance “involves benefits generated by enjoining the use of the 

defendant’s powers, such as tax collection, or enforcement of price or wage 

control.” Grosskopf & Medina, 32 Seattle U. L. Rev. at 912 (footnote omitted). 

Arkadelphia is an example of this type of restitution. See 249 U.S. 134. The rail 

carriers were only able to extract the excessive charges from their customers 

because the commission was enjoined from enforcing its commission rates. Id. 

at 145–46. Other regulatory cases follow suit. See, e.g., Panhandle E. Pipe Line 

Co. v. Fed. Power Comm’n, 154 F.2d 909, 912 (8th Cir. 1946) (holding that a
21 4/25/2024 3:22:12 PM

pipeline, which overcharged for natural gas while its challenge to the Federal 

Power Commission’s reduced-rate order was on appeal, was required to 

reimburse customers for overpayments and to also pay the expense of 

distributing the overpayments); see also Middlewest Motor Freight Bureau v. 

United States, 433 F.2d 212, 228 (8th Cir. 1970) (describing the Panhandle 

Eastern Pipeline Co. v. Federal Power Commission decision as “consistent with 

the general principle that a party who obtains a benefit from an improperly 

issued injunction has the duty to restore that benefit to those who have been 

injured by the injunction”).

In the context of wrongful injunctions, “[r]estitution is available almost 

exclusively in cases in which a sum of money or a specific property had been 

transferred from the defendant to the plaintiff on the basis of the preliminary 

injunction; thus, only ‘restitution in kind’ or ‘money had and received’ is 

available.” Grosskopf & Medina, 32 Seattle U. L. Rev. at 910 & n.32 (citing cases 

and describing “the remedy of restitution for wrongfully-issued preliminary 

injunctions [as] very limited”); see also St. Louis Sw. Ry. of Tex. v. Consol. Fuel 

Co., 260 F. 638, 640 (8th Cir. 1919) (holding, in a case where a preliminary 

injunction required the defendant to supply coal to the plaintiff: “It would be a 

grave reproach to the administration of justice if, when a court has wrongfully 

taken the property of one party and given it to another, it should be powerless to 

make restitution. The law is otherwise.”); Dan B. Dobbs, Should Security be 

Required as a Pre-Condition to Provisional Injunctive Relief?, 52 N.C. L. Rev. 1091, 

1141–42 (1974) (arguing that caselaw “may suggest not only that restitution will 

be denied unless the plaintiff’s gains are traceable to and identifiable with the 

defendant’s losses, but also that the gains must be directly traceable”). “Indeed, 

all thirty-two illustrations given by the Reporters of the Restatement of 

Restitution are cases in which ‘money has been paid’ or ‘property has been 
22 4/25/2024 3:22:12 PM

transferred.’ ” Grosskopf & Medina, 32 Seattle U. L. Rev. at 910. This limited 

application is reinforced by section 18 of the Restatement (Third), which 

recognizes that restitution applies only to “[a] transfer or taking of property, in 

compliance with or otherwise in consequence of a judgment.” Restatement 

(Third) § 18, at 244 (emphasis added). 

Focusing on “the true nature of the claim” sought by Modern Piping, 

Unisys, 637 N.W.2d at 156, restitution in the context of a wrongful injunction 

requires a direct correlation between the matter being enjoined and the claimed 

harm. See Bryant v. Mattel, Inc., 2010 WL 11463865, at *8 (C.D. Cal. Oct. 5,

2010) (“None of the case law on this issue allows a wrongfully enjoined party to 

recover all ‘unjust enrichment’ caused by the injunction. Most of the cases instead limit recovery to amounts compelled to be transferred by the injunction 

itself.”). That direct correlation is lacking here. Modern Piping argues that the 

University used the temporary injunction to take partial occupancy of the Children’s Hospital without entering into the separate agreement with Modern Piping 

required by the general conditions. But the temporary injunction addressed only 

those claims Modern Piping had already submitted for arbitration, which did not 

include the partial occupancy issue. The injunction precluded the AAA (and by 

default Modern Piping) from arbitrating the claims Modern Piping had submitted 

for arbitration related to the Children’s Hospital project in the same proceedings 

Modern Piping was arbitrating its Hancher claims. Nothing more, nothing less. 

The temporary injunction did not transfer or take any of Modern Piping’s arbitration claims from it. The injunction merely delayed the timing of the arbitration 

proceedings. Indeed, the AAA arbitrated all the claims Modern Piping had submitted for arbitration beginning in March 2017, once the temporary injunction 

was dissolved. Arguably, the interest accrued during the time period the arbitration claims were delayed would have a direct correlation to the injunction, but 
23 4/25/2024 3:22:12 PM

the amount awarded by the AAA included prejudgment interest that covered that 

loss. The temporary injunction made no mention of any other breach of contract 

claims that Modern Piping might have against the University but had not submitted for arbitration. Rather, the terms of the temporary injunction related only 

to the arbitration claims.

Modern Piping tries to create a direct correlation between the partial occupancy and the injunction by characterizing the University’s refusal to enter a 

partial occupancy agreement as taking Modern Piping’s property right to exclude 

all others. But Modern Piping misstates its “property” right with respect to the 

Children’s Hospital in making this argument. Modern Piping had a contractual 

right to additional compensation for the University’s partial occupancy, not a 

property right to exclude the University. The University owned the building, and 

Modern Piping was the mechanical contractor, one of several contractors working to construct the Children’s Hospital. This is not the type of situation at issue 

in City of Corning where the owner was prevented by a wrongful injunction from 

constructing a competing power plant and lost out on the profits it would have 

earned from using its own property but for the injunction. See 282 N.W. at 792–

93.

As the Restatement (Third) comments explain, “If there has been no transfer in consequence of the judgment that is later set aside, there is naturally no 

issue of restitution.” Restatement (Third) § 18 cmt. a, at 244–45. Here, Modern 

Piping’s partial occupancy breach of contract claim was not “taken” from Modern 

Piping by the temporary injunction enjoining arbitration proceedings with respect to entirely different claims.

III.

The district court erred in allowing Modern Piping to pursue the restitutionary damages it sought as part of its wrongful injunction claim. The judgment 
24 4/25/2024 3:22:12 PM

is reversed to the extent it awards Modern Piping $12,784,177 as restitution for 

unjust enrichment. The judgment awarding Modern Piping $21,784.50 for its 

costs and fees in getting the temporary injunction dissolved is affirmed. The case 

is remanded for entry of an order consistent with this directive.

AFFIRMED IN PART, REVERSED IN PART, AND REMANDED.
