Punitive damages

Section 668.3(1)'s comparative-fault reduction does not apply to punitive damage awards.

Godbersen v. Miller · filed 1989-04-19(1)

Because the aim of chapter 668 is proportional compensation, not punishment, we see no applicability of section 668.3(1) to punitive damage awards.

Special verdict requirements and consistency

Section 668.3(2) requires the jury to state each claimant’s damages without considering contributory fault and allocate fault percentages, while section 668.3(6) requires the court to ensure the special verdict is consistent with those amounts and percentages before discharging the jury.

Cowan v. Flannery · filed 1990-10-18(2), (6)

A negligence claim for damages resulting from injury to a person is now brought under the provisions of chapter 668 of the Iowa Code; liability in tort — comparative fault. This chapter requires a jury to answer special interrogatories as to the amount of damages each claimant will be entitled to recover if contributory fault is disregarded and the percentage of the total fault allocated to each claimant. Iowa Code § 668.3(2). The court should not discharge the jury until the court has determined the verdict or verdicts are consistent with the total damages and percentage of fault. Iowa Code § 668.3(6).

Section 668.3(6) allows a court to send an undischarged jury back to complete a verdict form it inadvertently left unfinished.

Grodt v. Darling · filed 1991-04-23(6)

Clearly, the jury had, through mere inadvertence, failed to complete the jury form. It simply made a ministerial error of omission. We do not believe that either party seriously challenges the right and duty of the court to order the jury to resume deliberations to correct this problem. See Iowa Code § 668.3(6).

Section 668.3(2) requires jury instructions when the fault of more than one party is at issue; it does not define which actions chapter 668 governs.

Waterloo Savings Bank v. Austin Ex Rel. Austin · filed 1993-01-20(2)

Rather, section 668.3(2) narrowly applies to a court’s duty to instruct the jury when the fault of more than one party is at issue.

Section 668.3(8) requires damages to be itemized by element, and each itemization must be supported by evidence or the plaintiff is entitled to a new trial.

Matthess v. State Farm Mutual Automobile Insurance Co. · filed 1994-09-21(8)

Because of damages itemization, the jury must now tell us what it is awarding for each element of damages. See Iowa Code § 668.3(8) (1989). And each itemization is a special jury finding that must be supported by the evidence. If such finding is not supported by the evidence, the plaintiff is entitled to a new trial.

Section 668.3(8) requires damages to be itemized, with proximate cause determined for each claimed item.

Johnson v. Knoxville Community School District · filed 1997-11-26(8)

Because damages must be itemized in this case, see Iowa Code section 668.3(8), at the new trial the jury should be given verdict forms that properly connect the issue of proximate cause to each item of damage claimed by the plaintiffs.

Recovery barred when claimant is more than 50% at fault

Section 668.3(1) bars a claimant from recovering damages when the claimant’s percentage of fault is more than fifty percent.

Section 668.3 bars recovery when the claimant bears a greater percentage of fault than the defendants combined.

Husker News Co. v. South Ottumwa Savings Bank · filed 1992-03-18

We need not resolve the issue, however, because on this de novo review we find negligence on the part of Husker greatly exceeds the combined negligence on the part of the defendants. Recovery is therefore barred under Iowa Code section 668.3 (contributory negligence a bar to recovery if claimant bears greater percent of fault).

Allocation of fault among released parties

Section 668.3(2)(b) requires the jury to determine the allocation of fault for parties released from liability.

Garren v. First Realty, Ltd. · filed 1992-02-19(2)(b)

In this case, the court was required to instruct the jury to determine allocation of fault for the parties who had been released from liability. Iowa Code § 668.3(2)(b) (1989). Without the admission of proof of the released parties, the trial court could not have instructed the jury and the jury could not have determined the allocation of fault of the released parties. We hold that the evidence was admissible to identify the parties released.

Section 668.3(2) requires a court sitting without a jury to apportion damages among parties at fault, but does not permit assigning a share to a released party whose liability is based only on fraud.

Freeman v. Ernst & Young · filed 1994-05-25(2)

Under chapter 668 the court, if there is no jury, must apportion damages among all “parties” at “fault.” Iowa Code § 668.3(2) (1993). ... Because Freeman could not have recovered from Neenan under a theory classified as “fault” under chapter 668, it was error for the court to assign a percentage of fault to Neenan.

Peterson v. Pittman · filed 1986-07-23(2)

In the trial of a claim “involving the fault of more than one party,” Iowa Code section 668.3(2) requires that the court or jury make an allocation of fault among each claimant, defendant, third-party defendant, and person who has been released from liability pursuant to section 668.7. ...

Beyer v. Todd · filed 1999-10-13(2)(b)

Party status and fault allocation

Section 668.3(2)(b) permits fault allocation only to claimants, named defendants, third-party defendants, and released persons, so fault cannot be allocated to nonparties.

Selchert v. State · filed 1988-03-16(2)(b)

We have repeatedly interpreted these statutory provisions to preclude allocation of fault to nonparties whether they be unidentified, see Baldwin v. City of Waterloo, 372 N.W.2d 486, 492-93 (Iowa 1985); dismissed prior to trial, see Payne Plumbing & Heating Co. v. Bob McKiness Excavating & Grading, Inc., 382 N.W.2d 156, 159 (Iowa 1986); known parties to an occurrence from whom no relief was sought, see Peterson v. Pittman, 391 N.W.2d 235, 238 (Iowa 1986); or acts of God, see Renze Hybrids Inc. v. Shell Oil Co., 418 N.W.2d 634, 641 (Iowa 1988).

Section 668.3(2)(b) requires the jury to consider a third-party defendant’s fault in the total allocation of causal fault when a contribution claim puts that defendant’s fault toward the claimant in issue.

Here Wal-Mart’s contribution claims against Laubscher and Lobaugh put in issue their fault toward the Kragels. ... The court also erred when it refused to instruct the jury to consider the fault of Laubscher and Lobaugh in the total aggregate of causal fault toward the Kragels.

Section 668.3 permits separate verdict forms to allocate fault for damages before and during an identifiable period of alleged failure to mitigate.

Greenwood v. Mitchell · filed 2001-01-18(3)

We think the inequitable result of the first trial can be avoided upon retrial by the use of separate verdict forms for the period prior to the plaintiffs alleged failure to mitigate and for the period that includes the plaintiffs alleged failure to mitigate. Nothing in the comparative fault statute requires that an allocation of fault be made in one verdict form in cases such as this, where the failure-to-mitigate claim is easily identifiable to a specific time frame.

Scope of fault comparison

Section 668.3(2) allows a jury to allocate fault to a highway worker who failed to exercise reasonable care for his own safety, even though the worker has a different duty of care from an ordinary pedestrian.

Kuta v. Newberg · filed 1999-09-09(2)

Iowa Code section 668.3(2) provides in relevant part: ... This principle does not, of course, totally relieve a highway worker from exercising care for his own safety.

Section 668.3(1) compares fault resulting in death or injury to a person or property, so a claimant’s fault in an enhanced-injury claim is considered when it proximately caused the injuries at issue.

Reed v. Chrysler Corp. · filed 1992-12-23(1)

In cases in which chapter 668 applies, the statutory requirement that fault is to be compared has reference to “fault resulting in death or in injury to person or property.”

Section 668.3 does not require an employer's fault or damages share to be allocated in a third-party tort action when the employer is not a party.

Sorensen v. Morbark Industries, Inc. · filed 1993-10-06(2)(b), (1), and (4)

The court finds that nothing in the statute requires the division of damages into the two pools Morbark suggests. The Sorensens’ employer is simply not a party to the action, and therefore Ch. 668 neither assigns the employer a share of the fault nor a share of the damages award.

Section 668.3(3) requires the factfinder in enhanced injury cases to consider both the nature of each party’s conduct and its relation to the damages when assigning fault percentages; causation alone does not determine the allocation.

Jahn v. Hyundai Motor Co. · filed 2009-10-09(3)

Further, the legislature in Iowa Code section 668.3(3) has expressly stated that “[i]n determining the percentages of fault, the trier of fact shall consider both the nature of the conduct of each party and the extent of the casual relation between the conduct and the damages claimed.” In this language, we conclude that in enhanced injury cases, the legislature has directed that the casual relation between the conduct of a product manufacturer and the resulting damages is one of the two elements to be considered in assigning a percentage of liability, but is not solely determinative as to the allocation of fault.

Treating two or more persons as a single party

Section 668.3(2)(b) permits two or more persons, including a released person, to be treated as a single party when allocating fault, which can treat a physician and hospital as one party for vicarious liability.

Biddle v. Sartori Memorial Hospital · filed 1994-06-22(2)(b)

In summary, we believe the district court correctly ruled that Dr. Watts’ settlement with Biddle extinguished any further claim against the hospital on a theory of vicarious liability. The doctor and hospital were properly “treated as a single party” for purposes of the release. Iowa Code § 668.-3(2)(b).

Effect of contributory fault on recovery

Section 668.3(1)(a) generally permits recovery despite a claimant’s contributory fault, reducing damages in proportion to the claimant’s fault unless that fault exceeds the combined fault of the other responsible parties.

McGuire v. Davidson Manufacturing Corp. · filed 2003-04-18(l)(a)

This section makes it clear that rather than barring recovery for a defendant’s negligence when the plaintiff is partially at fault, the Act merely reduced a negligent plaintiffs recovery by the percentage of fault attributed to the plaintiff.

Comparative fault—res ipsa loquitur and claimant fault

Section 668.3(1)(a) permits recovery despite a claimant's fault unless the claimant's fault exceeds the combined fault of the responsible defendants and other specified parties, with damages reduced proportionally; accordingly, a res ipsa loquitur plaintiff need not disprove personal fault to prevail.

McGuire v. Davidson Manufacturing Corp. · filed 2005-02-17(1)(a)

The Act provides: Contributory fault shall not bar recovery in an action by a claimant to recover damages for fault resulting in death or in injury to person or property unless the claimant bears a greater percentage of fault than the combined percentage of fault attributed to the defendants, third-party defendants and persons who have been released . . . , but any damages allowed shall be diminished in proportion to the amount of fault attributable to the claimant. Iowa Code § 668.3(1)(a). ... We find this reasoning sound and believe that when the Iowa Supreme Court addresses the issue it, like many other high courts, will find that in a comparative negligence system, plaintiffs using res ipsa loquitur need not disprove their own fault in order to prevail.

Reduction of consortium damages for the fault of the person providing the basis for the claim

Section 668.3(1)(b) requires consortium damages to be reduced by the percentage of fault attributed to the person whose injury or death provides the basis for the consortium claim.

James B. Wilson, As Administrator Of The Estate Of Lily M. Wilson, Vs. Farm Bureau Mutual Insurance Company · filed 2006-05-12(1)(b)

By reducing the loss of consortium claim by the percentage of fault which the jury attributed to the decedent, the district court did exactly what it was required to do under the law. See Iowa Code § 668.3(1)(b) (any damages for consortium will be reduced by the percentage of fault attributed to the person who provides the basis for the consortium damages); id. § 668.3(4) (the court shall determine the amount of damages payable to each party in accordance with the findings of the court or jury).

Section 668.3(5) requires the court, in a jury trial, to instruct the jury and permit evidence and argument about the effects of its answers to comparative-fault interrogatories; failure to explain the effect of allocating fault to a settling party does not require reversal without prejudice.

Mumm v. Jennie Edmundson Memorial Hospital d/b/a Methodist Jennie Edmundson Hospital, Emergency Physicians of Western Io · filed 2019-03-01(5)

However, Iowa Code section 668.3(5), regarding comparative fault, goes further.

Wickwire, 476 N.W.2d 69, 72–73 (Iowa 1991) (indicating that in a case with a settling defendant, the district court must instruct the jury that the plaintiff’s recovery will be reduced by the percentage of fault attributed to the settling party).

Comparative fault in nuisance damages

Section 668.3(1)(a) permits comparative fault to reduce or bar recovery for property-damage claims, but in a nuisance action it cannot reduce the recovery for diminution in property value because that would be an unconstitutional taking.

Dalarna Farms Vs. Access Energy Coop. · filed 2010-12-23(1)(a)

Section 668.3(1)(a) provides contributory fault may act as a bar to recovery ―in an action . . . to recover damages for fault resulting in . . . injury to . . . property.‖ Id. § 668.3(1)(a). ... Dalarna‘s recovery for other elements of damage, if any, caused by any nuisance found by the fact finder to have been caused by Access Energy shall be reduced in proportion to Dalarna‘s causal fault, if any. ... However, we further conclude that to avoid an unconstitutional taking, comparative fault principles may not be applied to reduce a plaintiff‘s recovery for the diminution in value of his or her property caused by the nuisance.

Apportionment of aggregate fault

Partners argues—without citation to any authority—that more than fifty percent contributory negligence on the plaintiff’s part bars any recovery, not just monetary damages. But the language of the provision does not state contributory negligence shall bar recovery. By its terms it applies “in an action by a claimant to recover damages.” Iowa Code § 668.3(1)(a) (emphasis added). ... Similarly, the goal of injunctive relief is to avoid future harm, not to provide compensation. ... We are not convinced A.D. is barred from equitable relief by its contributory negligence.

Section 668.3 permits the jury to apportion any percentage of comparative fault, and the comparative-fault issue should be submitted when substantial evidence could support finding the plaintiff even one percent at fault.

Tamra Bradley and Scott Bradley v. Timothy Tietz and Carol Tietz · filed 2024-12-04(1)

And comparative fault allows the jury to apportion any percentage of fault between the parties. Iowa Code § 668.3(1)–(3). ... And that video—showing Bradley’s general rate of speed, the weather conditions, the time leading to the crash, and the visibility of Tietz’s truck—contains sufficient evidence for a reasonable jury to find Bradley negligent and partially at fault for the collision.

Section 668.3(1)(b) bars a plaintiff’s recovery when the plaintiff’s contributory fault is greater in percentage than the combined fault attributable to the defendant.

Kleckner v. United States · filed 2019-07-19(1)(b)

Even if some percentage of fault could be attributed to Mr. Smith for failing to maintain a proper lookout, failure to yield or any of the other specifications of negligence set forth in Plaintiffs’ complaint, I nevertheless conclude that Mr. Kleckner’s own negligence is at least 51% of all fault that may have contributed to the collision. In other words, Mr. Kleckner’s contributory fault is “greater in percentage than the combined percentage of fault attributable to” Defendant. Iowa Code §668.3(1)(b). Therefore, Mr. Kleckner’s contributory fault bars Plaintiffs’ recovery. Id.

Subsection 668.3(2)(b) treats a vicariously liable vehicle owner and the negligent driver as one party for comparative-fault purposes.

Section 668.3(2) applies when fault is established and multiple parties are involved in the same claim, requiring allocation of fault among the specified parties; it does not authorize comparing medical-provider fault with the fault of a released original tortfeasor when the claims are separate.

Ellie T. Shimp, Zach Shimp and Kerri Shimp v. Timothy A. Gibbons, M.D., Chad H. Boyer, P.A.-C., Jared A. Knowles, P.A.-C · filed 2025-11-13(2)

Chapter 668 applies when fault is established and when there are multiple parties to the same claim. Iowa Code § 668.3(2); Schwennen v. Abell, 430 N.W.2d 98, 102 (Iowa 1988). That is not the case here.

Section 668.3(1)(a)’s comparative-fault bar applies to negligence claims, but comparative fault is unavailable as a defense to intentional torts such as assault and battery.

Sandra K. Mormann, Individually and as Administrator of The Estate of Augustin G. Mormann, and Daniel J. Mormann, Indivi · filed 2025-11-21(1)(a)

A jury finding that Mormann was more than fifty percent at fault would have barred his recovery for negligence. Iowa Code § 668.3(1)(a) (2021). But the comparative fault defense against torts included in Iowa’s Comparative Fault Act is not available against intentional torts such as assault and battery.

Section 668.3(2)(b) requires fault to be allocated among specified persons and permits the court to treat two or more persons as a single party.

Rhonda Baldwin, as of the Estate of Garrett O. Baldwin v. Central Iowa Hospital Corp., d/b/a Iowa Methodist Medical Cent · filed 2026-05-22(2)(b)

The preemption rule is also consistent with the Iowa Comparative Fault Act. The Iowa Comparative Fault Act requires the trier of fact to determine “[t]he percentage of the total fault allocated to each claimant, defendant, third-party defendant, [and] person who has been released from liability.” Iowa Code § 668.3(2)(b) (2022). Under the preemption rule, the employer’s vicarious liability already captures the full measure of its employee’s fault; the employer has already acknowledged its liability “for one hundred percent of the damages attributable to the employee’s negligence.” Ferrer, 390 P.3d at 845. Under the Iowa Comparative Fault Act, “[T]he court may determine that two or more persons are to be treated as a single party.” Iowa Code § 668.3(2)(b). An employer who is vicariously liable for its employee’s negligence is treated as a single unit with the employee for purposes of joint and several liability. Biddle, 518 N.W.2d at 798–99 (explaining that under Iowa’s joint and several liability scheme, the employer and employee are treated as one unit when the employer is vicariously liable). Because the employer and the employee are treated as a single unit, the employer already bears the full percentage of fault allocated to the employee. There is no separate “employer fault” to allocate because the employer’s liability is coextensive with the employee’s. Adding a negligent retention claim does not create a new source of fault to be allocated. It merely introduces a second path to the same liability that the employer has already assumed. “All roads lead to Rome in a case such as this.” Bogdanski, 408 P.3d at 1162.

Section 668.3 requires fault percentages to be attributed only to parties, so an unjoined medical provider cannot receive a comparative-fault allocation.

Lee v. Small · filed 2011-11-22

This is so, because no hospital or medical provider is a “party” to this action within the meaning of Iowa Code § 668.2 to whom fault can be attributed under Iowa Code § 668.3.

Section 668.3(1)(6) bars a plaintiff from recovering when the plaintiff’s fault exceeds fifty percent of the total fault.

Todd A. Mulhern, Individually and as Representative of the Estate of Elizabeth M. Von Linden v. Catholic Health Initiati · filed 2011-06-24(1)(6)

Significantly for present purposes, the Iowa legislature adopted a modified system of comparative fault under which a plaintiff found over fifty percent at fault was barred from recovery.

Section 668.3(2) does not limit chapter 668 to claims involving the fault of more than one party; the chapter applies when statutory fault is at issue even if only one party is allegedly at fault.

Graber v. City of Ankeny · filed 2000-09-07(2)

We must reject the plaintiffs argument because it is based upon a faulty premise. This court held in Waterloo Savings Bank v. Austin, 494 N.W.2d 715, 717 (Iowa 1998), that the legislature did not intend by the language used in section 668.3(2) to restrict the application of chapter 668 to claims involving the fault of more than one party. We concluded that chapter 668 applied to any suit in which “fault,” as defined by section 668.1, was at issue, regardless of the number of parties allegedly at fault.

Section 668.3 would bar recovery when the claimant’s fault exceeds the defendants’ combined fault, but the court held that it did not govern this case based on its filing date.

Collier v. General Inns Corp. · filed 1988-08-24

Since this case was not filed before July 1, 1984, it is not governed by Iowa Code section 668.3 (1987), which would, in this case, require that plaintiff be barred from recovery, since “the claimant bears a greater percentage of fault than the combined percentage of fault attributed to the defend-ants_”

Section 668.3(1) reduces or bars recovery based on a claimant’s share of fault, but its comparative fault defense does not apply to dram shop actions.

Slager v. HWA Corp. · filed 1989-01-25(1)

Under Iowa Code section 668.3(1), recovery is diminished in proportion to the amount of fault attributable to the claimant. Recovery, however, is barred if the claimant bears a greater percentage of fault than that attributed to defendants, third-party defendants, and released persons. ... After applying appropriate principles of statutory construction, we conclude the legislature did not intend to afford a comparative fault defense to a dram shop action.

Acts of God

Section 668.3(3) limits percentage-of-fault allocation to parties, so an act of God cannot be assigned a share of fault.

Renze Hybrids, Inc. v. Shell Oil Co. · filed 1988-02-23(3)

The trier of fact under the chapter is only to determine the percentage of fault of each party. Iowa Code § 668.3(3). The legislature did not put acts of God into this statute, and it is not for us to do so.

Loss of consortium claims
