Matthew McQuillen and Elizabeth McQuillen, individually and as limited co-guardians and co-conservators of Margaret G. McQuillen,

Appellees,

vs.

West Side Transport, Inc., and Clifford Charles Takes, Appellants.

Appeal from the Iowa District Court for Linn County, Justin Lightfoot, judge.

A semitrailer driver and his employer appeal from a jury verdict in favor of an injured motorist. The motorist moves to dismiss the appeal on the basis of an alleged settlement agreement. Motion to Dismiss Appeal Denied; District Court Judgment Affirmed.

May, J., delivered the opinion of the court, in which all justices joined.

Mark E. Weinhardt (argued), Danielle M. Shelton, and Jason R. Smith of Weinhardt & Lantz, P.C., Des Moines, and Kevin M. Reynolds and Richard J. Kirschman of Whitfield & Eddy, PLC, Des Moines, for appellants.

Matthew G. Novak (argued) and Bradley J. Kaspar of Pickens, Barnes & Abernathy, Cedar Rapids, and Joel T. Andreesen of Rodriguez & Associates, Bakersfield, California, for appellees.

May, Justice.

Margaret McQuillen suffered great harm when her passenger vehicle collided with a semitrailer pulled by a truck tractor. Margaret’s family (the McQuillens) brought this suit against the truck driver and his employer, a trucking company (the defendants). Following trial, the jury found that (1) the defendants had been negligent but so had Margaret, (2) fault should be assigned 73% to the defendants and 27% to Margaret, and (3) Margaret’s damages were $35,793,475. Based on these findings, the district court entered judgment in the McQuillens’ favor for $26,129,236.80.

In this appeal, the defendants argue that errors in the closing arguments require a new trial. The McQuillens disagree. The McQuillens have also moved to dismiss this appeal based on an alleged settlement agreement.

We deny the McQuillens’ motion and reach the merits. But we find no abuse of discretion in the district court’s handling of closing arguments. So we affirm.

I. Background.

A. The Accident. It became quite foggy near Anamosa on the afternoon of March 19, 2020. Margaret McQuillen was driving southbound on Highway 151. There was evidence that Margaret may not have had her headlights on. There was also evidence, which we will discuss more below, that Margaret may have been using her phone.

Meanwhile, Clifford Takes was driving an eighteen-wheel semitrailer northbound on Highway 151. Takes made an unprotected left turn, crossing in front of the southbound lane, to turn off Highway 151 and onto a side street, where he planned to park. “Unprotected” means there was no stoplight or other

traffic device that would stop the oncoming southbound traffic. This means that the southbound traffic—including Margaret—had the right-of-way.

Margaret’s southbound car collided with the side of the semitrailer. This was an “underriding” collision, which means that Margaret’s car slid underneath the semitrailer. The car’s “greenhouse”—the roof, pillars, windshield, and side windows—was basically sheared off.

The state patrol investigated the accident. This led to a citation against Takes for failing to yield upon a left-hand turn. Takes pleaded guilty to the citation.

B. Margaret’s Injuries. The collision caused extraordinary harm to Margaret. Her breathing and pulse had stopped before the ambulance arrived. She was finally resuscitated at the hospital, but only after prolonged CPR. A physician said she had been medically dead. Her injuries included severe traumatic brain injuries, lacerations, and fractures, including about one hundred fractures to her skull. She underwent lengthy brain injury rehabilitation. There is evidence that she will experience permanent neurological deficiencies.

C. This Lawsuit. In 2022, Margaret’s parents brought this lawsuit against Takes as well as West Side Transport, Inc., which employed Takes.1 The McQuillens alleged that Takes was negligent in several ways and that his negligence caused the accident. They also alleged that West Side was vicariously liable for Takes’s negligence. And they asserted direct claims against West Side based on its own alleged negligence.

1The petition also brought a products liability claim against Wabash National Corporation, the designer and manufacturer of the semitrailer. Those claims were dismissed before trial and are not relevant to our analysis.

West Side and Takes answered the petition. They both denied the McQuillens’ claims. They also alleged that Margaret’s negligence contributed to the accident.

D. Trial. Trial commenced on May 28, 2024. The jury heard seven days of evidence. On June 7, the court read the instructions to the jury, the parties made their closing arguments, and the case was submitted. As will be discussed more below, there were some objections during closing arguments. There were also some requests for mistrial, which the court denied.

Concerning the jury instructions: after much discussion with counsel, the court ultimately concluded that only some of the McQuillens’ claims should be submitted to the jury. For starters, the court declined to submit any of the claims of direct negligence by West Side. This left only claims of negligence by Takes, for which West Side would also be vicariously liable. As for these claims, the court submitted three specifications of negligence, namely:

a. Failing to yield the right-of-way upon a left turn; or b. Failure to maintain a proper lookout; or

c. Failure to discontinue operation of a vehicle under hazardous conditions.

As for Margaret’s alleged contributory fault, the court submitted two specifications of negligence:

a. Driving her vehicle without having the vehicle’s headlights illuminated when fog conditions reduced visibility to 500 feet or less; or

b. Failing to maintain a proper lookout . . . .

E. The Verdict. The jury found the defendants 73% at fault and Margaret 27% at fault. The jury found Margaret suffered damages of $35,793,475,

including several kinds of future damages, such as future medical expenses exceeding $10 million.

Based on this verdict, the district court entered judgment in the McQuillens’ favor for $26,129,236.80. The defendants then unsuccessfully moved for a new trial or for judgment notwithstanding the verdict. This appeal follows.

II. Arguments on Appeal.

The defendants argue that we should reverse and remand for new trial for three reasons. First, the defendants contend that the McQuillens engaged in improper closing argument by suggesting that the jury should treat a particular rebuttal witness as an expert. Second, the defendants complain that the McQuillens engaged in improper closing argument by suggesting that the jury could find the defendants negligent on grounds other than those described in the specifications. Finally, the defendants claim that the district court wrongly prevented them from arguing that future damages must be reduced to present value.

The McQuillens disagree with all of these arguments. In addition, the McQuillens claim that because the parties have settled, the appeal is moot.

III. Mootness Issue.

We start by considering the McQuillens’ mootness claim. An appeal can become moot if any opinion we might issue would lack any “force or effect in the underlying controversy.” State v. Hightower, 8 N.W.3d 527, 544 (Iowa 2024) (quoting Belin v. Reynolds, 989 N.W.2d 166, 171 (Iowa 2023)). For instance, if the parties have settled the dispute on which an appeal is based, that settlement can leave the appeal moot. See, e.g., State ex rel. Dobbs v. Burche, 729 N.W.2d 431, 435 (Iowa 2007). In those cases, we usually won’t decide the appeal

(although there are exceptions). Cf. Hightower, 8 N.W.3d at 544–45 (discussing the public-importance exception).
